A great experience. Work was completed quickly and to a good standard with an unexpected extra (sorting out the electrics for a light in the crawl space). Most tidy builders I have ever employed. Quick responses and good communication. I'd happily use Prime Contractors again

Extensions- 16 May 2017
Initially apprehensive about using mybuilder, we found David easy going, clear and concise from the offset. The work carried out was to a high standard and any changes or questions that arose he was all to happy to answer. We found him to be pro-active in his approach, open and honest with how much items cost and sensible when agreeing monthly valuations. Both of us work in the construction industry and it is enjoyable and a breath of fresh air when you get to work with people as straight forward a David. We hope to do work with him again and would be happy to talk with anyone who is considering taking him on for additional work. Many thanks, Rob and Brom

Bricklaying- 19 Feb 2026
The work involved with the job was explained in plain language beforehand. All preparatory tasks such as dismantelling the old structure and clearing the site of rubble took place. The timescale for the job was kept to and the start and finish dates were kept to. I was impressed with the work carried out and will use the firm again when i need building work done.

Extensions- 4 Dec 2023
Happy with the quality of work and team was very friendly, everyday leaving the house livable for me and my wife while work was ongoing. Sohail offered good advice throughout the project and ended with shell completed after 8 weeks. Definitely reccomend getting a digger for excavation as we started building walls after 6 days, very fast! There were some minor delays as there are multiple projects going on in parallel, fitting in with timelines which is understandable as the team is very experienced and in high demand. Snag fixes were done promptly and all work signed off with building control. I would happily work with Sohail & team again, they have left the job with another satisfied customer - I think they turned out to be the best people to do the job, highly reccomend!

What to ask a Surrey extension builder before hiring?

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

An extension builder in Surrey 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 Surrey 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 Surrey?

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 Surrey 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 Surrey 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.
