Restoration & Refurbishment- 2 Oct 2024
I just wanna express honest with you I met up with Mr John on two occasions and I told him everything I want confirmed we confirmed the price he sent us a spreadsheet but later on confirmed a figure once that was done he said send pictures. I’ll get the items for you and will get everything done for you in a time which was originally 2weeks . Then 2 month and half later he ignore my calls very unprofessional and has outstanding task he left and still not even correct , I am not able to go in to all the details but I tell you for free how I’ve been treated for the last few weeks mentally draining and for example he said let’s get his electrician because he needs the person doing the work side-by-side and if I’m honest, they’ve done nonsense because the media where the plug is is not correctly positioned in fact, the TV does not go in properly as they positioned it in the wrong place they didn’t check where the TV was meant to go initially I have to sort this out myself.

Hard Flooring- 23 Feb 2020
Andrei provides great communication and very professional service. He was very flexible and worked extremely hard to get all the work done in the shortest time possible, but he did not compromise on quality. He worked very efficiently and considering all the work he had to do, he still left the house clean and tidy. The attention to detail was second to none. I’m extremely happy with my new flooring and would definitely recommend.

Kitchen Fitting- 3 Jun 2026
We recently used ANM Efficient Solutions for a range of renovation works, including installing and tiling our kitchen, laying a wood floor, and fitting both internal and external oak doors. Max and his team were professional, hardworking, and committed to delivering a high-quality finish throughout the project. As with any renovation, a few challenges arose along the way, but the team approached every issue positively and found effective solutions without cutting corners. What stood out most was their determination to see the job through properly. They didn't stop until all the work was completed to a high standard and we were completely happy with the result.

CJ was excellent from start to finish. He’s reliable, punctual, and a true one-man band who took care of everything himself.

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.
