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.

Conversions - General- 9 Sep 2023
A great team of professionals! They were always on time, and tidied up impeccably at the end of every day. They suggested alternative ideas to mine which proved to be useful and they worked to their quote and within the timeframe. I wouldn’t hesitate in recommending Willex.

Sean did a full refurbishment on our house. He is the most organised and customer friendly builder I have ever used. From start to finish there was a plan of action and then a great group of qualified tradesman to execute. Like every refurbishment, we asked for changes and he always made us feel like the extras were no problem. I have no hesitation in recommending CG Carpentry. They are now our go to builders and in our next move he will be the first person I call.

Restoration & Refurbishment- 26 Jun 2022
Tommy was a wonderful perfectionist and has done beautiful work in our stairway and hallway which had needed refurbishment for a very long time. It feels brand new. The flooring is perfect both in the hall and staircase, and the walls are now perfectly smooth and painted immaculately. Friendly and accommodating, we will be hiring again for more jobs in the future, undoubtedly. Thank you.

Extensions- 14 Nov 2017
Quotation provided was within our budget. Works schedule provided to ensure clear list of work that would be completed by the builder and what needs to be supplied by ourselves. Approx timescale of 3 months work for completion. Workman were very punctual and all hardworking. At each stage of the renovation any additional works required were agreed before proceeding. Due to the condition of our internal walls we needed to agree additional work to replace them. Builder agreed to plaster board plus labour, which was as expected. All jobs at each stage were organised by the builder and at no stage were there any hold ups. There were some issues with the double glazing firm used but again A1 builders organised replacements and communicated with all parties to ensure the project completed on time. At any stage if something didn't look right from our original request we were consulted before proceeding. Example was we had originally requested two velux window in our extension but before cutting out we were advised that 3 would look better and let in more light. We are so glad we chose this option because A1 builders were correct. We also requested A1 builders to fit our Kitchen and tile our floor which again was in addition but we we agreed on a price before work started. All work was carried out to a high standard and exceeded our expectations. All workmen used by A1 builders were hard working and left work areas tidy before leaving the premises. Our house is now a home.

Kitchen Fitting- 12 Nov 2022
I am so happy with the work and professionalism of Tom and James. I had queried several companies and decided to work with G2 brothers based on how open and honest they were on the first visit for estimation of work. We discussed the work I wanted done, which was to replace the cabinets in the kitchen. We also discussed the budget I had and what the overall look I was going for. Throughout the whole project we discussed options, impacts and agreed together on next steps. They were a pleasure to work with, I will definitely use their services again. Great work!!!

Myself and my partner had a positive experience with Justin and the team, the three directors initially came out to our house and assessed the job, we immediately had a good feeling. We subsequently received the quotation not too long after and together we made some tweaks before giving them the go-ahead. Communication was good throughout the project even with material delays and unexpected issues with the build, we also added some extra works throughout the project which was accommodated and costs discussed. The project did run over slightly but that was due to the latter. The guys were a pleasure to have on site as well as any subcontractors that were used. We are really happy with the finished project. The extension has made our space into a now useable family home, we love it!

Carpentry- 8 Nov 2019
Lee and team did a great job. Lee assisted me with selecting doors and furniture at a great price much cheaper than I had seen online. They completed the job quickly and with minimal disruption all refuse cleaned up. Very pleased with the doors would not hesitate to use again and would highly recommend Lee to others.
