Painting & Decorating- 11 Sep 2022
I cannot rate these guys highly enough. They worked long hours for seven days in a row to complete this job while making themselves as unobstructive as possible. Their attention to detail is impeccable and the quality of the work is outstanding. Their pricing was very competitive. They were so helpful in all aspects including moving, and returning furniture, as well as performing other small jobs which had not been previously requested. They cleaned up afterwards, leaving the property cleaner than when they had arrived. I am happy to highly recommend them.

Bricklaying- 20 Aug 2025
Michael was hired to build a set of tiered retaining walls and steps in my garden. He was a pleasure to deal with whilst costing the job, gave a fair price and provided a detailed quote. In terms of getting the job done, Michael and Conor were superb. They were there when expected, they went above and beyond on multiple occasions when issues were discovered (not with their work), and at no point did they take the easy route. Rather, the attention to detail and consideration they put into how I wanted everything was exceptional and the communication throughout was faultless. I would confidently recommend MPE to anyone and will certainly be using their services again myself. The final bill was also exactly as quoted, and the standard of work was spot on. All round excellent.

What to ask a Crowthorne extension builder before hiring?

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

An extension builder in Crowthorne 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 Crowthorne 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 Crowthorne?

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 Crowthorne extension builder’s ability to deliver a result that meets your expectations.
