Extensions- 5 Oct 2020
Billy, Darren & the team have just finished the single side and rear extension & refurb works on my house, and they've done a brilliant job! From the start, quotations we're received promptly and competitively priced. Communication for commencement of works (during COVID-19) was always going to be uncertain but, Billy dealt with this really well and scheduled the work in as soon as was achievable. From the first day on site it was clear the team have worked with each other for years and are willing to put the extra time in to get the build done quickly, but correctly. Communication throughout build was processed well and the guys are on hand to respond to queries and questions at all times. We had a delay in the project which was unforeseen, but we sat down and came to an agreement and the extra work was carried out quickly and the project was wrapped up in really good time. I wouldn't hesitate in recommending Innovation for any building or decoration work to friends and family as the end result of our place is stunning! Special shout out to Jordan, Fog, Florin (wood work wizard) & Joy for their hard work throughout. Thank you Innovation!

His work ethic and workmanship was superb - he did everything we asked him to do - and more - within a pre agreed price which he completely adhered to. I cannot praise Rhys highly enough and would recommend him to anyone. He is highly professional in his approach and also very personable and friendly!

RMD Replaced three bathrooms, cloak, en-suite and family. The work was planned so that disruption was kept to a minimum and we were give practical advice throughout as we made the detailed decisions during fitting. The work, including cabinet making, was excellent and carried out with an eye for detail. Alex has a 'belt and braces' approach so everything was fitted to last even if it required additional work and preparation. It was all done to budget too and the pricing was fair, open and honest. RMD proved to be great quality, trustworthy, a pleasure to work with and we wouldn't hesitate to recommend them.

Extensions- 5 Feb 2019
We found Lee to be enthusiastic, reliable and approachable during the execution of our project. He was keen to deliver a project that was an overall success for us. His attention to detail with selecting matching bricks meant the extension blended seamlessly into the original build. The invoicing of stage payments was easy to understand and in line with our agreed terms. Lee came forward with a number of suggestions which significantly improved the project. We would recommend Lee for similar projects and wish Durrant Construction every success in the future.

John Burke Carpentry
Rating: 5 out of 5
Extension Builder in Windlesham
Hi there, I hope you're well. My name is John and I ve been in the building trade for 20 years. I'm a qualified master carpenter, and there isn't much left I haven't done. Im a bathroom fitter as well, so plumbing, tiling, plastering, is all second nature to me. I ve done jobs in every trade, when I was an apprentice all those years ago, that's how my boss at the time worked. Knowledge is power as they say. I based in Bracknell, and I can travel up to an hour from there. So as far as Dorking to the east, and the same distance in the other directions. As I said, in my 20 years of working in the trade, I ve done nearly everything there is, I'm a friendly guy and happy to answer any questions. I won't be the cheapest, but I LL be one of the best. I look forward to hearing from you. John

Groundwork & Foundations- 28 Feb 2024
We hired Nicholls construction for a large extension which was a 6 month project in total. We had an overall positive experience with them very friendly and helpful. Dan and his team were on hand to explain complicated issues that arose due to our structural issues and provide solutions. Whilst we stayed living on site they took care to not cause much disturbance by building temporary walls. In terms of budget we feel they were very fair with sticking to the agreed fixed quote and happy to sign a contract. We are satisfied with the outcome and would definitely recommend them.

Conversions - General- 25 Apr 2023
This was work to a commercial unit. Jason and his team were absolutely excellent. Sensible pricing and started and completed the work as he'd promised. Removed all rubbish and left it clear and tidy. He organised an electrician and plumber and found a sensible solution for a damp problem that was uncovered during the works. Highly recommended...and nice people to deal with too.

What to ask a Windlesham extension builder before hiring?

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

An extension builder in Windlesham 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 Windlesham 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 Windlesham?

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 Windlesham 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 Windlesham 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.
