I hired John to do my Outbuilding Shell only. The work included demolishing existing structure, foundations, Block and Beam, EPDM roofing, Cavity Block works and Soakway. All aforesaid works were carried to highest standards and I am very pleased with works. John is friendly, reliable and trustworthy. I would use his services again and recommend him to others.

Extensions- 31 Jul 2015
Kamil and team have been an absolute joy and a pleasure to work with during the construction of our kitchen extension. They are incredibly hard working, every morning 7.30am starts and when needed working weekends as well. Every little extra we have asked for has been no problem at all, solutions have been found to everything. Not only have they built the extension but made sensible and welcome suggestions to how things could be done differently for a better effect -e.g the lighting, sockets, boiler set up. All work is completed to the highest standards and cleaned up afterwards. I would have no hesitation in recommending them to anyone, we have already employed them to overhaul the shower and heating in the rest of the house later in the year. 5 STARS

What to ask a Waltham Forest extension builder before hiring?

Before hiring an extension builder in Waltham Forest or extension building company in Waltham Forest, 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 Waltham Forest?

An extension builder in Waltham Forest 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 Waltham Forest 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 Waltham Forest?

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 Waltham Forest 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 Waltham Forest 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
