Reviews
Trustindex verifies that the original source of the review is Google. Mark and his Team completed 2 projects for us 1) Removed and Replaced a 50 metre Boundary Wall 2) Complicated Site Clearance. Mark demonstrated excellent Management skills when planning and organizing the Projects. Marks Team are extremely polite and professional and were very responsive in dealing with issues that came up. As I sometimes work abroad, i needed someone i could trust to deal with all aspects of the Projects when i was away. We were very happy with the quality of the work and would recommend Mark and his Team to anyone.Posted on Neil O KEEFFETrustindex verifies that the original source of the review is Google. I was delighted to retain the services of Mark Dunne and his team from Capital Construction. After contacting some other companies, I was impressed with Mark's friendly communication from the very start and his value for money advice on design and building tradeoffs to achieve our goals while controlling the budget. His honest and fair approach to the project resulted in his company winning our business. He informed me of everything and took my approval on everything, giving me control of all the decision-making while advising me and navigating me from his expert point of view, as I did not have much experience in this area. This was my first home renovation project, and I'm delighted I hired Capital Construction as they took care of everything from start to finish, including meeting us at showrooms and arranging samples from trade suppliers for approval. Their design process was amazing also. They worked weekends and whatever it took to deliver the project on time. I have recommended Capital Construction to many of my work colleagues and continue to do so. Thanks again, Mark and all the team at Capital Construction, for your quality work. Wishing you continued success in 2026 and beyond AymanPosted on A ElgammalTrustindex verifies that the original source of the review is Google. We recently had the downstairs of our home renovated and transformed with Capital Construction, and we honestly couldn’t be happier with the entire experience. From day one, Mark was genuine, honest, and deeply invested in bringing our vision to life. It truly felt like a partnership — we weren’t just clients, we felt like part of their team. The whole crew was an absolute pleasure to work with. The work site was kept extremely clean and organized throughout the project, and the communication was always clear and consistent. We received daily updates from Mark, and they stuck to the agreed timeline without compromise. The team's passion and friendliness really stood out — not just with us, but with our neighbors and even our kids, who were always welcomed safely on site! It made the whole process smooth and enjoyable. A special thanks to Dean and Damien for all their hard work and attention to detail. The finished result is beyond what we imagined, and we’re so grateful to the entire team for making it happen. We highly recommend Capital Construction to anyone looking for honest, professional, and genuinely passionate builders. It’s rare to find a team that’s this easy to work with and this committed to your vision. Our house has been transformed into the most wonderful home and we are truly grateful.Posted on Linda LanaganTrustindex verifies that the original source of the review is Google. I had the pleasure of working with Mark and his team on a full renovation of my house from A–Z, and I couldn’t be happier with the results. They handled everything with professionalism, attention to detail, and great communication throughout the process. Not only was the cost very reasonable compared to other quotes I received, but Mark also went above and beyond by surprising me with a TV as a gift — such a thoughtful gesture! What really stands out is their after-work support. Even once the main renovation was completed, Mark and his team were responsive and willing to help with additional requests or adjustments. That kind of commitment is rare to find. I highly recommend Mark and his team to anyone looking for reliable, skilled, and customer-focused renovation experts.Posted on Fred radTrustindex verifies that the original source of the review is Google. I came accross Mark Dunne and Capital Construction after a number of negative experiences with builders with regard to quotes, returning calls and a general interest in my project. Mark and his team of builders, electricians, plumbers and other trades worked efficiently to transform my tired old house into a new build entirely. Mark was full of ideas and suggestions that vastly improved my original vision. It was not easy to work around an owner with 2 dogs but Marks team did so with good cheer. I never felt abandoned at any stage as inevitable problems occurred , as old radiators, pipework, re-wiring took place. Mark and his team were always on hand to offer advice or to fix the problem on hand. It was great to work with a company that has the client at the centre. Mark was more than understanding when my bathroom and kitchen tiles went out of stock and was more than willing to accommodate my desire to wait due to unsuitable alternatives. I would have no hesitation in recommending Mark and his team for your project or new build. Further photos to follow and a video is available on Facebook. Regards David LowePosted on Spiritual FeetTrustindex verifies that the original source of the review is Google. I’m delighted to highly recommend Capital Construction! When I bought my charming cottage last year, it needed a full renovation. After doing my research, I reached out to Mark at Capital Construction along with a few other builders. From our first conversation, I felt confident working with him. He even suggested I visit one of his current projects, which was amazing and gave me so much reassurance that he could deliver great results. Mark and his team worked wonders, transforming my cottage into a beautiful, cosy home for my little family. They handled everything—from a full strip-out and tackling rising damp to rewiring, replumbing with a new combi boiler, plastering, fitting new doors, installing a gorgeous bathroom, and laying stunning herringbone vinyl flooring, which I had dreamed of for so long. Their craftsmanship is truly exceptional, and the final result exceeded all my expectations. What impressed me most was Mark’s fair pricing and his commitment to staying within my budget without compromising on quality. Renovations can be daunting, but his professionalism and clear communication made the entire process stress-free. I always felt informed and confident that I was getting the best possible value for my investment. If you’re looking for a skilled, trustworthy builder who delivers outstanding results while respecting your budget, look no further than Mark and his team at Capital Construction!Posted on Paola BeasTrustindex verifies that the original source of the review is Google. We couldn’t have done it without you and your team! That’s exactly the message I sent to Mark when we were reaching the end of the full renovation they did in our house. Big project, with many moving pieces, and changes along the way. The Capital Construction team made it all happen, fast, with quality, adding and coordinating as many resources as needed, helping us make decisions on anything from insulation to flooring to roofing to painting to… you name it! We’re very happy with the results and how our renovated house looks, and we will certainly reach out to Mark and team for any future needs.Posted on Mauricio OdovaineTrustindex verifies that the original source of the review is Google. We used Capital Construction to upgrade our floors by installing an insulated concrete screed and new engineered wood flooring. The whole process was very straightforward and hassle free. Mark and his team were great to deal with and very helpful. Mark guided us through the whole process and gave some great advice. Absolutely delighted with how it all turned out and would highly recommend 👍👍👍Posted on Niamh O'SheaTrustindex verifies that the original source of the review is Google. Couldn't recommend Capital highly enough. Mark and his team made everything as simple and straightforward as possible and provided lots of advice along the way. Delighted with the end result. Cheers MarkPosted on John CarrollTrustindex verifies that the original source of the review is Google. Mark and his team converted a bathroom into a home office for us. They are such neat workers.
