Carpets & Lino- 13 Sep 2026
Couldn’t recommend this guy enough! He was incredibly helpful, professional and went above and beyond to help us when we were in a bit of a difficult situation. He genuinely saved us from what could have been a massive issue and we’re so grateful for his help. Really friendly, knowledgeable and clearly takes pride in his work. It’s rare to come across someone who cares that much about helping their customers. Would 100% recommend and will definitely be using him again in the future. Thanks again!

We hired Bawa to install new fencing, and he did a fantastic job from start to finish. You can immediately tell he’s an all-rounder who understands construction very well. The work was carried out efficiently and to a high standard. Bawa has a great attitude, is very hard-working, and clearly takes pride in what he does. Communication was easy throughout, and the whole process felt smooth and professional. It was a real pleasure having Bawa work for us, and I wouldn’t hesitate to recommend him.

Extensions- 15 Jun 2026
We hired Mac to complete a single storey extension which involved digging foundations, removing internal walls and installing a number of RSJs. Mac completed all of the work ahead of the tight schedule that we asked for as we had our first baby in the way. His workmanship was high quality throughout the project, he was dedicated and did not have multiple jobs on the go at once unlike other builders. we couldn’t be happier with the result and would hire Mac again for any future work. Mac was very friendly and approachable through the project and always had time to listen to our requests and even gave me some tips on other DIY projected had going simultaneously! I have no negative words to say about him.

Bathroom Fitting- 5 Nov 2019
I met up with Peter, told him what needed doing and he provided a detailed quote within days. I handed over a set off keys and basically left him and his team to get on with it! This was a time restricted job, he purchased all the material and provided all the receipts. I returned a week later to find the job completed to the highest standard surpassing my expectations. I will definitely be working with Peter again in the future and I would highly recommend him.

What to ask a Cranleigh extension builder before hiring?

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

An extension builder in Cranleigh 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 Cranleigh 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 Cranleigh?

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 Cranleigh 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 Cranleigh 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.
