Conversions - General- 17 Apr 2026
A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Two rooms in one day. The work was done to a high standard and everything fit as it should. He left the job tidy and neat, when I walked into the room, it was if the floor had laid itself. We also hired him to install a double glazed window for us, again work done excellently and no less left

Extensions- 19 Sep 2009
A really positive experience. Rupert built a side-return extension to our kitchen, and renovated our back garden. We were lucky to find Rupert. He was reliable, honest, competent, and good value. He has a good instinct for what will look good, and clear views on what won't, so you can trust him to build something you'll like, and to do it well. He is also good company.

Tiling- 10 May 2019
As per the previous reviewer I don't usually hire tradesmen when there is only limited feedback, but given the glowing report I took the risk. And it proved to be a great decision. Astrit was great - clear communication, arrived when he said he would, sought our opinions on the key decisions and gave some great advice, before ultimately doing a great job for a reasonable price. A pleasure to deal with and will hire again for any future tiling work. Thanks Astrit.

Extensions- 23 Dec 2022
ELB Construction completed some major garden works for me and constructed a garden office. It was a big piece of work with a lot of earth moving, significant foundations and a lot of brickwork. The ELB team, specifically Jimmy the site manager, were fantastic, always giving me the right advice about things I was not knowledgeable about, always focussed on a quality finish and flexible when we had some challenges with our neighbours. The finish is great, communication was always open and honest and they were very competitively priced. My brother in law is in corporate construction and was specifically very impressed with the quality of the brickwork that Jimmy and the team produced. Thank you to the whole team!

Extensions- 9 Feb 2019
I had the pleasure of working with Habib on the renovation of my house. My review of his work during renovation: 1- He has done excellent job in rewiring the house. he segmented each floor and kitchen and put them on separate ring, he expanded consumer box for future growth as well as installing wired smoke and security alarms 2,3 - He fitted pipe and installed unvented cylinder system with water softener perfectly including multiple heating control zones which I can control each floor individually (I love it). 4- he built a beautiful and prefect extension in garden, he considered all building regulations such as structural integrity, fire safety, energy efficiency, damp proofing, ventilation and other key aspects that ensure a building is safe. In addition to above he has very good personality and he is approachable to discuss changes or add new tasks to job (unlike some builders whom don’t like it). Throughout the course of the renovation, Habib was a consummate professional. He was accurate in his initial assessment of the scale and cost of my project. Good work takes time to complete. Patience is required when you work with a perfectionist. Although my project took time to complete, I have a wonderful outcome and a work of art now. I can recommend him highly and without reservation. Thank you, Habib, At the end I would like to thank Jake for his part and hard-working during renovation of my house. Hamid

What qualifications and experience do you have as an extension builder in Mortlake?

An extension builder in Mortlake should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Mortlake?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Mortlake extension builder’s ability to deliver a result that meets your expectations.
