Extension Builder in Brentwood
I am an experienced builder providing both handyman services and larger building works. My background includes loft conversions, extensions, and full property renovations, with hands-on experience from strip-out and structural work through to plasterboarding and finishing. I currently work within a construction team delivering a wide range of internal and external building projects, which gives me strong practical knowledge across multiple trades. Alongside larger jobs, I also take on general home repairs and maintenance, including furniture assembly, TV mounting, door and lock repairs, plumbing fixture replacements, sealing, and other household tasks. I’m happy to help with both small jobs and more time-consuming projects. I am reliable, tidy, and focused on delivering quality workmanship. For bigger jobs, I can arrange additional skilled help if needed to complete the work efficiently and to a high standard.

Extensions- 18 Sep 2019
To start off with the job went reasonably well - we were happy with the workers and the progress. but when we neared completion the work slowed up we waited 3 months for a response from Jordan. we had an issue where his plasterer hid the plumbing access in the wall. - This cost us £500 to sort and re-decorate so we came to an agreement that this was fine and at the time i presumed that Jordan was going to sort out the building control. so we then chased and chased but obviously since he had his money he wasn't interested he answered the phone and hung up. so we called building control and there are 2 small bits to fix which are all due to his work not being up to scratch. obviously i will be paying out for this - so please be careful when using him and dont pay him until you have all of the documents as he will not resolve any issues after being paid. i have had 2 previous building projects and this was by far the worst experience going. avoid dont use him thanks

What to ask a Brentwood extension builder before hiring?

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

An extension builder in Brentwood 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 Brentwood 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 Brentwood?

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 Brentwood 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 Brentwood 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.
