Landscaping- 12 Jan 2021
Brady and the lads did a fantastic job building me a fully insulated rendered block garden room. I went for Ellis Phillip because both Brady and Andrew are genuinely decent and trustworthy guys. They were tidy from the onset and even covered my whole driveway in a layer of board and plastic sheet before the job started to prevent and damage and mess. Good quality of work and finish. Brady uses the same teams (eg plasterers, electrician, etc) for his jobs and they all work well together and communicate all aspects of the job with each other which helps alot. Nothing was too much trouble - we made numerous last minute changes throughout the job and he was happy to accommodate them. Job finished in a decent time scale. We're extremely pleased with the finished result and would definitely use again and recommend to friends and family.

Excellent Builder I would highly recommend Louis. He was very polite, professional and really cracked on with the job from the start. He worked hard and did his absolute best to fix the poor and unfinished work left by the previous builder. His attention to detail and attitude were excellent, and I really appreciate the effort he put in. Great job, Louis!

What to ask a Amersham extension builder before hiring?

Before hiring an extension builder in Amersham or extension building company in Amersham, 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 Amersham?

An extension builder in Amersham 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 Amersham 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 Amersham?

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 Amersham 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 Amersham 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.
