Extensions- 8 Nov 2024
After much deliberation, I picked Daron and his crew for our job. From start he was very flexible, honest and accommodating. We quickly understood each other. His crew showed up when agreed and hit the ground running. The shell for our side extension was up in 4 weeks, quicker than expected. Quality of work was really good. As I am now taking over to finish the job, I also really appreciated that both Daron and his guys were more than happy to discuss next steps, or how to do some of the things. Also, if I get stuck I know I will be able to give them a ring and get them booked in to complete some of the items. It was a real pleasure working with them all, and should I have another job come up, I will not hesitate to call them again.

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!

What to ask a Crowthorne extension builder before hiring?

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

An extension builder in Crowthorne 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 Crowthorne 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 Crowthorne?

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 Crowthorne 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 Crowthorne 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.
