Do extension builders near me need insurance?

While it isn’t a legal requirement, most builders carry public liability insurance to cover accidental damage or injury during work. Always ask to see proof of insurance before agreeing to a project.

Do local extension builders offer guarantees on their work?

Yes, many local home extension builders in your area should provide a guarantee covering their workmanship for a set period, often lasting several months to a few years depending on the project size. Always check what the guarantee covers before work begins.

What should I ask before hiring an extension builder?

Ask about previous work, project timelines, cost estimates, and payment terms. It’s also wise to discuss materials, planning permissions, and how any unforeseen issues will be handled. You can easily view examples of previous projects of extension builders near you on MyBuilder.

How much deposit should I pay for an extension project?

Deposits usually range from 10% to 20% of the total cost. Make sure the payment schedule, scope of work, and conditions are clearly written into a contract before the extension project starts.

The work was completed efficiently and to our expectations, they also cleaned up throughout the project. We have no hesitation in recommending L.A.

Harry McSweeney Building Contractors completed a kitchen extension for us this year. The planning was brilliant, we felt all our wishes were taken into account and included. The communication throughout the build was great. And the finish was more than we could have hoped for. I now love my kitchen family space!

Kitchen Fitting- 27 Apr 2019
Our experience with sonny was great. He was very professional including giving a detailed broken down quote and was always quick to communicate. Once the job started he was on time everyday, he tidied up after himself and he got the job done to a high standard. As the build happened he was flexible with changing things that we wanted to change and to help with solutions when things needed to be done differently. He was always very friendly and happy to answer questions and pick up items we needed for the build. I would definitely recommend Sonny and I would use him again in the future.

I got a good feeling as soon as I met Darren from Keystone. Sometimes, I find builders and tradespeople difficult to talk to but Darren was super friendly and chatty, as we went through my plans. Darren's input was really helpful and he and his team got the work done quickly and efficiently; also couldn't believe how tidy they were, thought there was going to be mess everywhere! Amazing job, at a really good price and great communication throughout...can't recommend highly enough.

Extensions- 3 Oct 2022
The Guys were great, excellent work, put the hours in to get the job done, 99% of the work is done they're just coming back to install the windows once they've been manufactured. But the rest of the work, I can't fault it having had a terrible experience whilst building the house a few years ago these guys went above and beyond, and proved there are good builders around. Great attention to detail and skilled. Would happily recommend them and use them again on future building projects.

High and Wide converted our double garage into a home gym with artificial grass and ground work. As soon as we spoke to Will over zoom we felt confident with our project. We were over seas so building the trust and relationship was so important for us to be able to go ahead with High and Wide. Wills knowledge and expertise were second to none and he answered all our questions with detail and explanations. His construction knowledge is excellent and nothing so too much effort. I would highly recommend High and Wide to anyone planning a project!

Plastering- 2 Feb 2020
Joe was great from start to finish. He did an amazing job plastering the ceilings and walls in our house. They look great. He also built a stud wall to separate our living room which is excellent. He was always on time and stayed to finish the job. He was flexible when we had extra plumbing and electrical work which meant extra work chasing in wires etc. I can't recommend Joe highly enough. Thanks for all your hard work!

Went through my apprenticeship with a company called John Dennis. After my 4 year apprenticeship i stayed with john dennis for a further 5 years, within this 9 years at john dennis i done the lot from new builds, renovation and extensions. Done work from private to council work 1st fix, 2nd fix. After 9 years went onto the new build, doing everything from kits, roughing out the houses and doing the 2nd fix. I have recently started up my own company and cover every aspect a joinery.

Craig was fantastic and professional. He completed the job both very quickly and to a very high standard. He took a terrible sketch that I made on a piece of paper and turned it into a fantastic fitted bookcase in a very awkward space with sloped ceilings. I would highly recommend.

Morgan did a great job building the deck around our garden office. He's very polite and hard working, and even with small challenges during the course of his work, he managed to deliver the project in time and with highest standards. Left the area super tidy and ready for us to enjoy our new deck. Definitely recommend.

Graham replaced the windows at the front of my property. Four windows in total. The quality of work was superb with a close attention to the finishing off. The work area was kept very clean at all times. The job from start to Finnish was excellent. Completed on time and at the price quoted. Graham’s strengths were everything I would of expected from a trades man. Turned up on time from start to Finnish. Kept me informed of the process till the end. Was a very friendly chap. And I have already recommended him to 2 other friends for work of which he as all ready completed installation of 1 job.
