Kitchen Fitting- 9 Jul 2026
I hired Blend for a light house renovation. It started off really well then towards the end he ghosted me. No reason given. He didn’t answer phone calls or texts. There was no fight or disagreement. There is no decent reason why he shouldn’t communicate with a client. You can simply just say you have another job or you are not interested any longer. You don’t ask a client to buy stuff knowing you are not going to show up. It is an unacceptable and unprofessional behaviour. Because of this it’s cost me time that I can’t get back. But I guess it is what it is. I had to find another builder to complete the job. Some of which was not done properly. For example: my kitchen sink was leaking both inside and out. Had to buy a new toilet as something was broken while he was refitting it and etc. Pros: Blend is a nice and easy person to deal with. He is generally a nice guy. Tiling ✅ Cons: Finishing is not so great. could be a lot better. I also found patches and over paint on doors and others.

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.
