Bricklaying- 12 Nov 2016
Dear Brian I have tried to contact you on several occasions to complete the job. I really do not wish to leave negative reviews all over the Internet. Will you get in touch? Just ignoring the situation will not go away as I am now in receipt of your insurance documents and want to resolve amicably. I put you on notice to get in touch within 7 days. If I do not hear back I'm afraid I will have to start the legal processes as you give me no other option. I hope to hear from you within the allotted timeframe and do hope we can avoid litigation in this circumstance. Thank you. Dawn

Extensions- 26 Sep 2022
Excellent work with the garden office/gym. Finished really nicely and exactly what we were looking for. Took quite a while but well worth the wait. We requested a labour quote and worked with Alf on a receipts basis for material and other costs. This worked out perfectly for us both. Alf's initial estimate of the materials cost was virtually spot on, which is very impressive given the inflation rate for building materials. Thanks again for all your hard work!

Fletcher and his team did a 5 metre extension on my kitchen, installed a new kitchen, new doors and new floorboards throughout the downstairs. All members of his team were absolutely outstanding. The workmanship looked extremely professional and it turned out so much better than I expected. If there was ever a problem, it was never a case of ‘we can’t do that’ there was always a solution and I never felt stressed as I knew that whatever cropped up, they dealt with it. They were all so friendly and I felt at ease with them all the time. When I went to work, I left them to their own devices and they always locked up perfectly for me. I can’t recommend them enough and I will certainly have them back when I need more work completing.

Kitchen Fitting- 11 Oct 2018
Mohsen went above and beyond with our kitchen face lift. He did exactly as asked, to a very professional standard. Mohsen is very hard working, has high standards and was reliable.

What to ask a Lewisham extension builder before hiring?

Before hiring an extension builder in Lewisham or extension building company in Lewisham, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Lewisham 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 Lewisham 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 Lewisham?

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

How long will the extension take to complete?

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.

Do you offer a guarantee for your work? Most Lewisham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
