Extensions- 18 Jan 2023
We highly recommend THG building solutions, they have built a double story extension for us, and from start to finish they were always on time, polite and professional on every aspect. Most importantly they delivered what was promised according to the initial budget and on time! No delays or surprises, just honest and reliable service. We have been approached by several neighbors to comment on how beautiful the extension looks and how quickly it was all done! Overall we’re very happy and glad that we chose Charles and his team as our builders.

Hi, I have been lucky enough to have a family who have a well established building company and I've learnt a great deal from them. I have also been a foreman on a site, building nursing homes so i gained alot of experience through that. I am a very clean, tidy worker and I always make sure the job is exactly as the customer wants it.

Bricklaying- 24 Aug 2016
Nick has been an absolute pleasure to work with. He was always very polite, his work was neat and tidy and very considerate of others around him. He took the hassle out of building/renovation and even helped out with organising things once his job had finished. He originally came to quote on possible subsidance, which ended up not being subsidence at all and instead did some internal renovation for me by bricking up some doors and knocking through walls. I can definitely recommend Nick and will get him to do some work for me in the future.

Replaced a rotten external single door. The existing door frame was reused, as per request. This frame wasn't perfectly square which Alex had to compensate for. Alex arrived on time and completed the work without any unresolved issues, taking all offcuts and old door away for disposal.

Simon was polite, efficient and very tidy. He listened to what I wanted (which was a little unusual), asked questions at each stage to make sure he was doing exactly what I wanted, advised when he thought an idea wouldn’t work and gave his own suggestions, communicated well with all the other tradesmen involved, got them all to do their bit in a timely fashion and worked very hard. I am getting him back to do another job imminently!

Extensions- 13 May 2026
Agim completed a ground floor extension for me in 2025 and I would not hesitate to recommend him for similar work. The quality of the work was excellent and the team worked tirelessly for months to ensure it was completed on time and for a reasonable price. Agim was able to adapt quickly when any unforeseen problems occurred, always clearly communicating possible solutions to help keep the project moving. Having people in your home can be difficult but Agim is very respectful and considerate, making sure to put our needs first. The results are fantastic and Agim continues to help snag any minor issues that come up. I couldn’t be happier with how things went, testament to his professionalism. Thanks Agim for all your help on this project.

What to ask a Dorking extension builder before hiring?

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

An extension builder in Dorking 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 Dorking 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 Dorking?

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 Dorking 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 Dorking 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.
