Plumbing- 15 Nov 2025
Incompetent company. They were contracted to put a new shower cubicle in one bathroom and regrout and make good and regrout in another bathroom. This company are completely incompetent. We had to take out all of the grouting that they did as it was so poor and all of the sealant. It was clear that they had no experience of fitting bathrooms or tiling at all. They did not even seal the sides of the shower unit against the walls, so water would be able to run right out of the shower cubicle. They did not connect the waste pipe and water came straight through the ceiling. I would not recommend this company to do any work.

An excellent job received. Matthew put in a real shift during the day and the work was completed to an excellent standard. After several years and several builders our leaks seem to be repaired. Would highly recommend.

Extensions- 4 Jan 2026
I hired Amrit based on positive reviews, but my experience was extremely poor. The work showed all the signs of a cowboy builder. I’m sharing this to help others avoid the stress, delays, and financial risk I went through. 1: No Respect for Contract or Deadlines Contract deadline was 15th September, which he completely missed. Despite delays, he demanded money almost daily. When I referred him to the payment and work schedule he signed, his response was: “I didn’t read it, I just signed it.” 2: Dangerous and Unprofessional Working Practices Brought in unqualified workers, many of whom could not speak basic English. He ignored safety standards throughout the project and wanted to use the same unqualified workers for gas work, which is extremely dangerous. When I objected, his response was: “Don’t worry, you will get a new house if it blows up as you have insurance.” 3: Work failed multiple building control inspections. He eventually refused to cooperate with the building inspector.

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!

Cocis Construction Group done the full interior painting of our 5 bedroom house and we are really happy with the result. The team was polite and worked very hard every day. They kept things clean and finished everything on time like they said they would. The paint finish looks great and the whole house feels fresh again. Would definitely recommend them if you need painting done.

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.
