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.

Architecture- 4 Jun 2026
I recently worked with this structural calculation engineer for a project that required precise drawings, and I couldn’t be happier with the outcome. The calculations were spot-on, and the drawings were clear and detailed, making the process seamless with my builders. Not only was the quality top-notch, but the pricing was fair and transparent. Communication was excellent throughout, and they delivered on time. Highly recommended!

Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

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

An extension builder in Walthamstow 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?

Your Walthamstow extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Walthamstow?

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 Walthamstow extension builder’s ability to deliver a result that meets your expectations.

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.
