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- 6 Jun 2021
I requested quotes from 10+ builders, regardless of their price I already knew I was going with KHbuilder as instantly they seemed genuine & trustworthy! Hasan never changed his price during the project which is a fear many have during a build, he has a great team, friendly and always courteous. His workmanship is very good, therefore he is now also doing my patio and garage, he has great suggestions and contacts which has saved us money. His attention to detail and reliability really does shine through, our neighbor is now also doing the exact same 4 meter extension with a new kitchen move, the fibre glass roof and the bifolds all starting to take shape and look fantastic, just search for KHBuilder on instagram where they have posted the progress so far of all the work being done! We will genuinely miss all the guys being around. A very rare find in the building trade!! Thanks KH Builder...

What to ask a Addlestone extension builder before hiring?

What qualifications and experience do you have as an extension builder in Addlestone?

An extension builder in Addlestone 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 Addlestone 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 Addlestone?

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 Addlestone 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 Addlestone 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.
