“I engaged DMC Building for my home renovation in 2021 whilst in the height of Covid and continual lockdowns. They created a fully self contained loft in an existing roof space. At all times the Site Manager Joel Glassman was polite and efficient and was in constant contact with me during the build keeping me informed of what was happening. The DMC team kept all subcontractors on schedule during difficult circumstances and my job was complete in a timely manner. They offered valuable suggestions throughout the job and were open to making changes along the way. I am very happy with the result and now live happily in my renovated home.”

“From the first meeting with Doug I was confident that we had chosen the right builder. It also helped that Doug came recommended by a friend of mine. I am sure that there are cheaper builders out there but you would not receive the same service, professionalism and quality finish as we ended up with.

My wife and I thoroughly recommend DMC Building.”

– Mark Todman

“Throughout the process foreman Joel kept us informed with regular updates and we appreciated his expert advice. This job was carried out very professionally and the team were polite and respectful at all times. I have no hesitation in recommending them to anyone considering a renovation.”

– Ian Clement

“The team at DMC were a pleasure to deal with. They were professional, organised, polite, turned up when they said they would and their quality of work was exceptional. We would highly recommend them.”

My wife and I engaged DMC Building to build our garage and family room extension.
The end result is everything we had hoped it would be.

Doug from DMC helped us with the design and finishes and we are thrilled with the end result. The assistance he gave us in designing the stairs and joinery made all the difference. Their attention to detail transformed a fairly simple room into something very special. We highly recommend DMC to anyone looking to do an extension or renovation.

– Greg Schultz

Another thing we really liked about how Doug approached the project is that nothing was a problem, everything had a solution.

We chose Doug without hesitation and so the project began. Joel is what I would call a Doug’s right hand man, he is the guy that makes things happen. If it wasn’t for Joel’s tireless attention to detail it would have been a very expensive exercise.

They are truly unique in their approach, very trustworthy and hard working. I would not hesitate to recommend them to anyone with the highest regard. Thank you DMC, you made our dream come true.

We had Doug, Joel and their team completely renovate our 1950’s weatherboard house. Their teams were incredibly helpful and professional, we had an incredible working relationship. We are two people who’d never done anything like this before, we felt like we were helped along the way. Every step of the way they explained what was happening and what would be needed from us. They were very much apart of ensuring our vision for our family home coming to life.

Not just throughout the build but also the aftercare. Anything that needed a little adjustment after moving back in, they’ve been attentive and helpful.

We’d absolutely recommended DMC. Building for anyone looking for quality, professional and affordable builders.

Kate Torta

From the start DMC placed a huge emphasis on quality and recognising the importance of the finer details of the build. They didn’t disappoint.

There was a daily proactive focus on delivery and the site was very professionally managed by Joel.

They delivered a significant project to tight timescales, to a high standard and I am extremely happy that we chose them.

Highly recommend DMC as a company and the integrity that they demonstrated in all interactions.

Thank-you Doug, Joel and Matt.

Mark McAdam

Doug, Joel, Ben and Hayden really are the dream team. They made our ideas a reality and took care of every detail. They turned our attic space into a fabulous first floor master suite. The quality of the finish is outstanding. Thank you DMC.

Natalie O’Brien

Doug, Joel and their amazing team renovated our home at the start of covid. They were professional meticulous and respectful during obviously a very uncertain time. They happily addressed all our concerns, and provided a before, during and after service that has been fantastic and we are thrilled with our beautiful home.

Varda Goodman

We engaged DMC Builders to renovate our home in Mosman after being referred to them by a drafting company. We are truly grateful for the recommendation and want to pass this onto to anyone considering their service.

Doug and Joel along with their team were a pleasure to deal with, facilitating a quality renovation and making the transition of our home a very simple and straight forward process.
The project management of our build was second to none, from the very beginning to the end. Joel was brilliant to communicate with and was always there to answer any questions and assist with important decisions.

DMC Builders have an exceptionally talented, meticulous and obliging team of trades. They moved at a rapid pace from the first day on the job and finished the project well within the expected time frame.

We are thrilled with the result and would highly recommend DMC Builders for the professionalism and workmanship.

Lidia Killeen

Doug, Joel and the team at DMC have been outstanding in completing the renovation and first floor additions to our family home in Drummoyne.

From helping us to get DA approval through to completion of the project the team were outstanding.

They were extremely professional and well organised throughout and the exceptional project management skills meant the project was well organised from day 1 to handover.

Not only did they finish the job earlier than the contracted date, they managed to do so during a supply chain crisis and had us in for Xmas as promised.

I would definitely recommend DMC for anyone wanting high quality, trustworthy, professional and well organised builders.

Greg Hannan


DMC were very professional and having a foreman on site everyday meant that things were kept to schedule and to a high standard. If there was ever a problem, Joel and Peter were on the phone immediately to offer solutions and to get our input. They worked with us throughout, the process was smooth and transparent and we are delighted with the end result. They’re a team of really nice people and it was a great experience all round. Thank you Doug, Joel, Peter and Amanda.
Trevor and Vivian

Doug, Joel and their team were fantastic to deal with from go to woah, and instrumental in turning our vision to reality.

I can highly recommend them.
