Extensions- 16 Oct 2019
Not trust worthy, does not follow the contract, he pulled out in middle of my work in house three times. Never finished on time. Promised to come back and finish The fence and the toilet never come back despite numerous phone calls. I have leaking toilets in the wall big pigments of dampness on the wall paper on the wall adjacent to toilet. Promise to do the roof tiles then he said I cannot do it. Fitted the kitchen units wrong and did not connect the sink overflow pipe to the macerate ( leaking water under sink. Flooring tiles not even still have prominent corners . Front driveway is cracked as he promised to dig and put concrete but last minute changed his mind and put only cement and new slaps. Water pipe outside house is leaking . The stairs carpet and the wooden stairs not painted rightly and the carpet is not fixed right it is out. I paid him all the money left only 150 pounds but never come back to paint fence, summer house finishing and loft ladder. Brought materials and his workers and brought bills never saw some of it. Taken some materials in his van and never discussed this issue. Work meant 6 weeks and now 8 months and still not finished. Do not hire him he and his workers are not up to standards. Will love one from builder. Com come and see the unfinished and damaged in my house.

Groundwork & Foundations- 2 Dec 2025
Working with Sebastian and Jonny was an absolute pleasure from start to finish. From day one, it was clear they and their team take genuine pride in their work and it shows in what they do. The entire team was incredibly courteous and professional, and as we have a mid terraced house they did their best keeping the hallway clean and dust free throughout the project. The quality of their work speaks for itself, and their attention to detail made the whole experience stress-free. I would highly recommend them without hesitation and would absolutely work with them again.

We are a southwest London Based loft and kitchen extension specialist. Our working area is very small with 90% of our jobs in Wandsworth and any work outside this area is never more than a mile or two away. With over 15 years experience in this area we know inside and out how these properties were built so when it comes to structural alterations you couldn't be in safer hands.

Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Bathroom Fitting- 2 May 2024
I have employed DL Construction to install a new kitchen and bathroom. They are still working in my house but so far their attitude towards their task and helpfulness have been exceptional. I can not comment about the final product yet but I am sure everything would be finished to a high standard. Nothing seems to be a problem for Javi. He always says 'yes please' and I think that is his middle name. I couldn't have asked for better. Well done (so far) Javi and everyone in DL Construction.
