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.

Windows & Doors (Wooden)- 30 Jun 2015
Jonathan has a very professional approach to his work, ensuring everything we required was quoted for in detail. He recognised we wanted good quality windows for a good price and we are very happy with the standard he provided. Needless to say this was at a very good price as well. During construction he fitted everything perfectly, kept to the agreed provision dates and ties, was very tidy and with very pleasant disposition. I have no doubts or qualms about using him again. PS he does like a coffee now and again; milk with no sugar and no biscuits. I always believe in keeping workers well watered!

Extensions- 15 May 2017
Rob and Richard were fabulous! Always punctual, always kept me informed as to what was happening, gave me great advice when decisions needed to be made, were really organised and brought in very good sub-contractors where needed and dealt with all people involved in the build, kept the site tidy and safe at the end of each day, the work was completed to very high standards and well within the time frame agreed. I would highly recommend RSJ Builders and really love my new kitchen extension.

Bathroom Fitting- 18 Feb 2026
Excellent work from Mike and his team. They kept me informed throughout with regular progress updates and pictures, which I really appreciated. They pay close attention to detail and do the job right rather than cutting corners. As a landlord, I was able to stay completely hands-off and let them get on with it. No chasing for updates or wondering if they'd show up – they were reliable and professional throughout. They started early each day, put in a full day's work, and left everything neat and clean. Would recommend and use them again in future.

Extensions- 29 Jan 2015
PM Building epitomise what a modern day, professional building firm should aspire to be. Transparent pricing, a friendly team working 6, sometimes 7 days a week to get the job done quickly, an eye for detail and very high standard of final finish. All comms and the overall work is run through Bart, who answers to phone, text or email quickly and frequently outside normal working hours. This is ideal if you work during the day and cannot be around to oversee things directly. We also got PM Building to make us a bespoke kitchen, again very high quality and millimetre perfect. If I had to find some negatives, they are not the cheapest company you could find, but there again you get what you pay for; also, we developed a few issues with some retaining walls in the garden, however, they returned when I contacted them long after the work had finished and fixed them! All in all, an excellent, honest and professional company to deal with. I would, and have, recommended them to friends...nuff said.
