Cathy & Stephen Bone

"We would just like to say a big thank you to you, and your team of employees for providing an outstanding service in the recent renovation of our home. Admittingly we were very apprehensive to start extending our home as we were concerned about how the house would look when completed and also concerned about disruption. A visit from Keystone immediately resolved these issues as time was spent explaining the entire process of the build in Layman’s terms (for the first time renovator), and we were made to feel confident and at ease and comfortable with your knowledge and explanations provided to both of us.

We are also highly impressed with the professionalism and courtesy your team provided to us. Their knowledge and support made our decision making processes much easier. All the tradesman involved in the renovation process were prompt, courteous and very meticulous in their work. The finished result has exceeded our expectations. We wanted our home to look like it was a new home and the finished result speaks for itself.

Once again thank you for your patience and dedication in building our now new home that we are extremely pleased with. I would have no hesitation in using keystone or recommending keystone to other individuals looking to do a similar renovation."

Reginald Moodley- Penrith NSW

"I am so very glad we chose Keystone to do our first floor addition and then to subsequently build a new property from scratch for my son. Their workmanship is second to none that I have seen and the service and tradespeople they used were fantastic. We were kept informed at all stages of the project and were very happy with the outcome. I recommend you consider Ralph and Stephen for your next project as they are men of high integrity and I know you will not be disappointed with their service, advice or workmanship."

Tracey, Jason, Liam & Mackenzie Brown

"Thank you so much for all your dedicated hard work and especially your consideration to our family during the renovation of our home. It’s the little things that your team does that make all the difference and helps the very uncomfortable experience of having your home renovated a little easier. Ralph, you have always been very easy to work with. Anything that we have asked for you have sorted out. We are so happy with our new home and are very grateful for the fantastic job that you did. You should be very proud of your work and the team that you have working for you.

I was warned by lots of friends that when you renovate it’s an awful experience to have people in your home... This was not the case with your team. They were always considerate of our privacy and we actually enjoyed having them around. Likewise with the contractors that you use. They became such a big part of our lives, it took a while to get used to not having them around! We would not hesitate to recommend Keystone to anyone in need of a builder. Thank you again."

Troy, Deanne, Christian and Lexie Worsley – Erskine Park

"To all the team at Keystone,

A very big (and very belated) thank you for the wonderful job you all did on our house. It’s just like a new home and suits our bigger family perfectly and as for the timing it was just perfect.

Thank you once again we will happily recommend you to family and friends."

Neil Moodley – Glenmore Park

"My wife and I had a home built in Glenmore Park about 4 years ago. We were quite particular about what we wanted and the features. Keystone Home Additions were always willing and accommodating to incorporate these changes and additions and would give us good advice along the way on points we had not considered. The staff was very friendly and kept our premises spotless and clean. Nothing was too difficult or out of there way. I will definitely use Keystone Home Additions for my next building project."

Chris and Jim – Harrington Park

"Many thanks for building our first floor addition. The end result is spectacular and well beyond our expectations.

The whole process was professional, on time and on budget. The tradesmen were all brilliant and meticulous.

Thankyou for the great communication between the Keystone team and ourselves, as you were always available to answer any questions straight away which was much appreciated and made our build a pleasant and stress-free one.

We would not hesitate to recommend Keystone Home Additions, and in fact, we already have had many enquiries regarding the build and were only too happy to pass on Keystone’s details. Once again many thanks."



"To Ralph and your team a big “thank you”! You’ve exceeded our expectations and made our dream reality. You can be very proud of your work and the team you have.
To everyone who is reading this with intention to build a first floor addition, your search should end here. You’ve found the right team for your project.
Like a lot of people we heard so many “horror stories” about living through a renovation/ addition. We took a long time to research and meet with different builders until we finally arrived at Keystone Building Services. Their honesty, integrity and professionalism made us feel comfortable right from the first meeting and once our decision was made they did not disappoint. Ralph and his entire team have an amazing work ethic, are very polite, considerate, helpful and patient and even Keystone’s subcontractors were very reliable and professional. Our first floor was finished in what felt no time at all and I literally lived through it every day as I was a stay at home mum with a small baby at the time. They worked every day with minimal disruptions to our lives and before leaving they always made sure the work site was cleaned up. Whether it was outside or at a later stage inside. With every day we could see progress. Ralph and his team were always patient and accommodated all our wishes and changes along the way. We could not have been happier with the result and the service we received."

Dee, Chris, Patrick & Carah
