"My name is Joan. I am an elderly widow and I needed some maintenance work done on my home. I found Precision
Building in the yellow pages and called John Rafferty. I could not have found a more helpful and knowledgeable person to assist me. He guided me through the process with patience and kindness. Precision Building completed a variety of work from concrete underpins, footings, stormwater pipes, ceiling replacement etc.. I was particularly pleased to see the pride the workers showed in their work. I cannot recommend Precision Building highly enough."

"After discovering damp issues in our newly purchased home, we contacted Precision Building. John promptly came to inspect the house and was able to formulate a plan to correct the issues. Carl and his team always arrived when promised and worked till all tasks were completed to a high standard. Precision Building showed honesty, professionalism and took pride in their work. They kept us updated daily on their progress and treated our home with respect. John, Carl and their team fixed our drainage problems and we have no hesitation in recommending Precision Building."

"It has been a pleasure to deal with John and the team at Precision Building for my drainage works. From the first site meeting with John, I was extremely impressed by his knowledge, his customer service and dedication to his clients. The works were performed at a very high standard but also extremely quickly to minimise disruptions. Nothing was too much trouble for John and he was more than happy to go the extra mile to ensure I was informed with the progress of the works. I would not hesitate to recommend John and the team to my friends, family or anyone else needing expert advice and quality building, drainage, foundation or pier work done."

"We contacted at Precision Building for advice with respect to a number of modifications/corrections to our house. Precision Building provided clear, sound advice with respect to the necessary work. Part of this work was reviewed and approved by our insurance company. All modifications to our new bathroom, pier replacement, floor levelling and moisture management issues were effective, completed within a clear time-frame and done to our complete satisfaction. At all stages of the work there was clear communication between us and John our Precision Building representative. Our specific requirements were always kept in mind and we were grateful for their many suggestions, guidance, and ability to fulfil these requirements. All aspects of the work were professionally conducted, without exception. This work required a variety of trade people and we were impressed with their communication; advice; quality of work; attention to detail and daily post-work clean-up; also their courtesy and consideration of our privacy in the midst of renovations Subsequent follow-up/advice is equally noteworthy. On the basis of our personal experience we are pleased to recommend Precision Building to prospective customers."

"I had the pleasure of working with Precision Building when initially replacing the piers and concrete foundations at my parent's weatherboard cottage in Warners Bay. Dealing with John, I felt at all times that the focus was on the best outcome for us as a family, and he was incredibly generous with his time and knowledge. The experience and workmanship was simply exceptional, so when there were other things to be done. We went straight back to them. On the whole it was the sort of experience with tradespeople that you can hope for, but seldom receive. An absolute pleasure. Cheers."

"Bob and I decided to have our Laundry converted into a bathroom / laundry. We contacted "Precision Building" for advice on design, layout etc. We contacted three companies and John was the most knowledgeable and passionate by far.
He also organises the entire team of tradesman which made us feel comfortable that we would not have to chase the different tradesmen who do the job. Our new bathroom was soon forthcoming with expert advice and service. The work commenced within a few days and carried out by expert tradesmen, to all our satisfaction. We were more than happy with the work and communication during this process. "Now our once drab laundry was turned a luxury bathroom/toilet/laundry area, which we are proud to show our relations and friends the overall luxury transformation."

"We were in need of some pier work for our older home in a tight time frame. My husband found John at Precision Building who came to our rescue. He quoted a reasonable price quickly and started the job promptly with no fuss. He was obviously skilled and experienced and knew what he was doing. John set up what was needed, did the initial work himself and his co-workers carried out the rest. Really hard working and exceedingly polite gentlemen. They communicated all the way, were there when they said they would be and did what they said they would. The job was completed within the tight time frame we had, within quote and we could not have been happier. We'd recommend John and his team to anyone needing pier work without hesitation. We wish Precision Building all the best and thank you for the job you did for us."

"We contracted Precision Building in August 2016 for concrete underpinning and stabilisation on our home Our initial contact was with John who arrived promptly at the agreed time, was courteous and attentive to our concerns and was thorough in his inspection. He gave us an initial diagnosis of our problem which was later confirmed by Carl. The agreed work was begun some 6 weeks after the initial meeting by Precision Building's competent team who always arrived at 8am each day, were polite and hard working and kept us informed of the progress of the work being performed. The after project follow up was exemplary with John arriving at three agreed times to monitor the remediation work which was done extensively and thoroughly. So satisfied with the work done by Precision Building that we again contracted them to perform further work on our home in November 2017. The same professional, timely and thorough service was provided. The work site was left neat and tidy and returned to its original condition. The underpinning service provided by Precision Building comes with our highest recommendation. All of the expectations a home owner requires were met promptly and expertly by Carl, John and their team."

"Dear John and Carl. Many thanks to you and the team for the hard work and expertise which helped with our renovation. We appreciated your open, honest and friendly advice all along the way. Chris and I continue to marvel at your multi-disciplinary team of expert tradesmen and the professional approach. With your help we have added to the value of our house and will continue to use your team again when we purchase another property. They say you can't turn a pig's ear into a silk purse, but together we came close."

"Selecting a contractor feels like a lottery, you hear so many horror stories but based on my experience I would have no hesitation in recommending the team at Precision Building. My second level would flood intermittently in heavy rain and I needed help as the issue was getting worse. I knew that this was going to be major works and an expense I didn't want to face. I called John from Precision Building and he came out to the house, investigated the problem and talked through what would be needed to fix the issue. He explained the works and I learnt more about my drainage and house from him than I had in all the time I lived there! My experience with Precision Building has been very positive, from beginning to end all the team have been friendly and competent. John always returned my calls, answered any questions and he continued to communicate well throughout the job. The trades team showed up when promised, had a great attitude, did quality work and they also cleaned up better than I expected. This gave me great confidence and reduced my stress but I also waited several months before writing this testimonial as I wanted the weather to test out the works. I am happy to say that I can finally relax every time I hear rain now. Thank you and great job."

"I would highly recommend John and the team from Precision Building for any drainage work to be completed. John's passion and knowledge for what he does is second to none and we felt very comfortable working from our very first meeting. John is very easy to get along with and that filters down to his team. The team were professional, efficient, accommodating to our needs and the after sales service was a pleasant surprise in an industry that does not always accommodate this. A big thanks to John and the team for a job well done!"

"If you need a job done, just get John Rafferty from Precision Building to come and look at it - then give you a quote -there is no need to ask anyone else! Seriously, John is the friendliest and most honest guy you will meet. We trusted him totally with the work we needed doing both under our house and on the roof. Then we met Carl - it was he and his young offsider Nathan who came each day and replaced the main beams under our house. These guys did that without ripping up the floor and worked in a space only a few feet high!!! And guess what, they didn't so much as break a tile on the kitchen floor or put any cracks in the walls - these guys know what they are doing!!! John, Carl and the team from Precision Building are true professionals. Actually we think John is a perfectionist (Carl probably is too). Before the job was done, John took pictures and a video of the damage under the house and on the roof. Then John explained the job to us and gave us the quote. We did not go to another company as we knew instantly that he knew what he was talking about. During the job, Carl kept coming in and making sure the floor was stable etc. Then after the job, once again it was followed up with pictures and a video of the finished work. We couldn't be happier with what PRECISION BUILDING did for us and would fully recommend their work to anyone.
Give Johnny a call...we did...and now we live in a very stable house - with a roof that won't leak!!!!"

"We can't recommend John, Tyler, Nathan and the team highly enough. Always cheerful and easy to get along with, they also tell it like is and offer solutions without just pointing out problems. The quality and efficiency of the work was great, and the results have been as promised. John and the team went above and beyond to ensure we were kept informed throughout the process, and they happily put up with endless questions from an inquisitive five-year old boy. We'll definitely use them again for other projects."

"Precision Building piers are a company I have gladly recommended to my friends. They were the only company (out of eight) to return my call, John provided great advice on work to carry out prior to repacking to provide a lasting final result. Cannot fault them at all, an approach of progressively lifting the house over a few weeks rather than rush the job provided me with a lot of confidence. All in all, only company I will recommend to my friends and family."

"It has been a pleasure to deal with John and the team at Precision Building for my drainage works. From the first site meeting with John, I was extremely impressed by his knowledge, his customer service and dedication to his clients. The works were performed at a very high standard but also extremely quickly to minimise disruptions to the tenant living at our rental property. Nothing was too much trouble for John and he was more than happy to go the extra mile to ensure I was informed with the progress of the works. I would not hesitate to recommend John and the team to my friends, family or anyone else needing expert advice and quality work done."

"During the storms of 2014 my house in Warners Bay was flooded due to previous shoddy renovation workmanship where a room had been added under my house however appropriate drainage was apparently considered not important. Whilst my insurance company covered the cost to replace damaged carpet & belongings, they also left me the ultimatum; carry out repairs to rectify the drainage or next time I won’t be covered. After contacting several companies to gain quotations (of which some never bothered to turn up) I found the team at Precision Building Services to be the most professional & knowledgeable towards providing the solution to my issue. After engaging their services, the work was carried out with speed & professionalism. Whilst they had to dig up my front yard, their assistance in reshaping to assist in drainage away from the house & rejuvenating my once lush garden beds was greatly appreciated. I would highly recommend the team at Precision Building Services to carry out rectification works of this kind."

"Both Stephan and I, have been worried about movement under our house for a few years. Steph had lacked up and pack our piers himself but they continued to sink, causing cracks in various rooms throughout our house. When we saw the add for Precision Building in the local Newcastle " The Post" Newspaper. Advertising that "if your house is moving, sinking or cracking up, that we should give John a call" so we did. We also called another company and left our details but they never returned our call. When we called precision building we left a message and John then got back to us and arranged a convenient time to pop around to have look. After John had completed his inspection of our piers, we all sat down together and he went over everything in details and gave us his honest opinion of what we had to do. He showed us pictures and then gave us the price for the work required. John was very professional and we felt totally at ease with him, in that he new what he was talking about, and my husband and i both felt that we could trust John. He didn't try to sell us anything we didn't need and he made us feel very comfortable in dealing with him to fix up our piers and structural wall. During the process of the job, they never at any time, did anything without explaining the task clearly to us. They were so friendly and professional and their work is top class. The little bits of advice in dealing with storm water getting under our home was invaluable and is working a treat in dealing with the long term water problems. Carl and John and the team are professionals and are very passionate about what they do and clearly care a lot for their clients. But most of all, we loved their honesty and dedication to do things properly. We would highly recommend Precision Building to anyone who needs any type of building services and we would definitely use them again."

"Excellent work, good customer relations - professional follow up. I have no hesitation recommending Precision Building, they were easy to work with, the Team are friendly and professional. They did quality work, cleanup and followed up until I was satisfied. They did extensive drainage work and followed up after big rain to see that the job was tested. Really excellent."

"Great job. Great service. We are part of a Strata so the decision was always going to be drawn out however John was very patient and good at explaining his solution for our problem (repair/replace piers and level under the flooring). Price was competitive. Turned up multiple times to answer our ongoing queries, job was completed within the given time frame with no unexpected additional costs. Our committee was very impressed and now seeking advice/quotes for our next large job. Very knowledgeable and professional. Would highly recommend."

"John advised us on which piers needed replacing and provided feedback regarding the work to be undertaken. We had large sandstone piers that had to be removed and replaced. All work proceeded smoothly and without any dramas. The quote was accurate and he returned to check on any movement. Highly recommended."

"Precision Building recently completed some much needed work to address drainage and rising damp issues, as well as replacing some old concrete piers. John and the team answered all my concerns with patience and understanding. All the work progressed smoothly, with each step explained. The boys were punctual and polite and ensured that the site was tidy and safe at the end of each day and obviously took pride in their work. I am very happy with the results and quality of the work, which had added to the value and safety of my home. I have no hesitation in recommending Precision Building for any work and would definitely use them again for any future work."

"Quality work. Problems fixed. I had significant problems with failing retaining walls, poor (non-existent) drainage and structural damage (caused by the lack of drainage). Precision Building did an excellent job of reviewing the problems, suggesting a solution and completing the works.
The team were all professional and friendly, and rightfully are clearly very proud of their high quality of workmanship. I would not hesitate to recommend Precision Building to a friend. I will be hiring them again for further works."

"We would highly recommend the Precision Building team. From start to finish we were very impressed with our retaining wall. John explained every aspect of the job and regularly checked in regarding the jobs progress. Both Nathan's were great builders and took pride in their work. The team ensured that the job was completed to high standards and attention to detail was great. We are very happy with our retailing wall and will definitely be using for future projects."

"I would highly recommend Precision Building to anyone for renovation work. From the first time John came to my home, he relaxed me about the idea of renovating my bathroom, toilet, and laundry. John was very friendly and seemed very passionate about his work and accommodating to ensure that every detail was completed to my liking. John created a great design that has made the whole area seem much bigger, and I love my new bathroom/laundry. Carl and the workers were always courteous and unobtrusive to have in my home. I have employed Precision Building to renovate this year further."

"I would highly recommend Precision Building to anyone who requires any building work attended. From the moment of contact to the completed job. They were professional, prompt and their workmanship was of the highest quality. Working with them made the whole process very easy especially for a single woman. All the team and tradespeople they use were happy to explain anything in a language I could understand and kept me informed throughout the many jobs. The work required included bathrooms, verandas, retaining walls and concreting around the entire property including driveway and pool fencing. No job was too big or too small for them. The team of Carl, John, Nathan, Nathan and Chad were always polite and approachable. They were very understanding to minimise the disruptions to my neighbours. John is an asset when it comes to shopping for the tiles and accessories for the bathroom by accompanying you to ensure you have enough tiles and appropriate fixtures. All the tradespeople e.g. painter, roofer, concreter, tiler, electrician and plaster etc contributed to the highest quality completed project."

"Precision Building have recently completed some drainage work around the perimeter of my house due to too much moisture getting into the subfloor. John, Nathan, and the team were very friendly, easy to speak with, communicated every step of the way and ensured I understood the work that was being completed. There was never an awkward moment. The owner was even onsite at times to ensure the best outcome was being achieved. The end result is fantastic, tidier than expected, and finished sooner than anticipated. All that's left for me is to laugh at the rain when it can no longer reach beneath my house. Honestly 100% recommend these guys! One of the workers was even nice enough to bring my bins before I could lol. Thank you again."

"We recently had a lot of work done at our property and we are so so happy with the outcome but the whole process as well!

Can not recommend them highly enough and so grateful we found them!"

"I was in need of a drainage solution to deal with surface water running along my home's piers. From the initial meeting to the final inspection, I could not have been more impressed with the professionalism and attention to detail shown by John and the entire crew. Everything was explained in exacting detail and I was kept informed of the progress along the way. Very happy with the provided solution and the quality of the work. You'll be in good hands with these guys."

"Great work by the Precision team. We engaged them to help with drainage/water damage issues on our +100 year old house in Lambton. John was excellent to work with throughout the project, and Nathan, Nathan & Will did a very tidy job in a quick timeframe, despite some difficult root systems right beside the house that they needed to navigate. We would happily recommend them, and have done so already."

"I recently used Precision Builders, particularly John Rafferty and his team, for a complicated foundation issue and couldn't have been happier. The team thought outside the box, and were very straight forward with tough conversations, while also understanding and accounting for budgetary issues. I really appreciated the human aspect of this company and have already scheduled them for the next project."

Marion Shepherd

"In 2022, the team at Precision Building completed a sizable job at my property, that was performed above and beyond any service I have ever experienced before, commencing from the very first visit for a quote. The site was located on a difficult bend on a major road, which the team handled in an extremely safe and courteous way to passing public and adjacent properties. The project's scope consisted of planning, engineering, site excavation, structural underpinning and extensive drainage remediation & installation, construction of retaining walls, installation of an expansive driveway/ parking spaces. The project was undertaken in clear stages that were communicated to us at every step. There were points where the builders gave me the option to alter the plan for a better outcome, and I am very glad I was given the option because the result was far superior to what we had initially imagined. The end of project clean-up was thorough, and the later check-in was very thoughtful, I could tell the team were so proud of their work. I can't recommend Precision Building highly enough. We have further work to complete on our property and will be enlisting their services without a doubt."

"We were returning customers of Precision Building and recently completed our home renovations with them. A few years ago, they replaced our old pillars and roof. This time they handled a full kitchen renovation, added a new upstairs bathroom, replaced old windows, and more. It was a big project and took some time, but we’re very pleased with the result. Carl, John and his team were always professional, respectful, and clearly experienced. Carl also works with highly recommended tilers, electricians, cabinet makers, plumbers, and other tradespeople—all of whom delivered detailed, high-quality work. We would confidently recommend Carl’s team to anyone. We’ll definitely reach out to them again for future projects."

With no expectations I reached out to John regarding next steps on a project that had come to a halt, and John was happily able to get us back on track with his attention to detail and depth of experience.
