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.

Extensions- 31 Oct 2020
This man gave me a good quote for an extension; much needed for my disabled husband. I needed a wet room and bedroom to accommodate his needs. To my horror (and expense) I discovered that he had no experience whatsoever. He was keen and polite but did not know that he was required to speak to building control. His response when I asked him was ‘oh yes’ tell him he is welcome to see what I have done. He had no idea how to read plans and kept blaming the architect for his lack of understanding. Given the hash he was making my benefactor appointed a site manager. He would not allow this. I moved out for a month (at great expense) with my disabled husband so that he could continue the build. Through this time I had no contact except from the building inspector who told me to get him off the job because he didn’t know what he was doing. The site was on a hill and no consideration had been given for a potential landslide which potentially could kill us. He was asked to leave the site given his ineptitude but his was after he managed to afford a new van out of us. 18 months on and at great expense I may just be moving in to my extension. The toll it has taken on me and my husband is catastrophic. He presents as a very nice man and actually did a lovely job on plastering over the damage he had created in my kitchen. I am sure, from other reviews, that he is an excellent plasterer however, should he answer your request on a build, don’t do it. Any of this is untrue H?

He dug the footings for the Conservatory & the retaining Wall, for the Patio. He did all the brick & block work, internal plastering & painting. He also built a purpose made conservatory, which included altering the roof to a small hip & two valleys. I am a retired builder & carpenter and was very satisfied with his work.

Handyman- 8 Mar 2022
Simon did a great job of fitting our loft ladder and as a result we gave him the job of fitting our new kitchen. After getting a quote fro a leading Kitchen Company, Simon said we can do it cheaper and better. We gave him the go ahead. True to his work he and his team Dave and Alistair sourced the kitchen including appliances and carried out the work. The kitchen took some time as we had to wait for a back order of some of the items. I can honestly say the project turned out well. We now have a brad new fully fitted Kitchen for less than originally quoted. The work was to an very high standard, The team made sure everything was clean and tidy at the end of each day. My wife and I will never use any other builders in the future. We have already earmarked them for decorating the whole hose and fit a new staircase. They are adept at Plastering, plumbing, painting, floor laying, Blind fitting and assembling units all to the best possible standard. I would never go to anyone else for work.If you want a good professional job then look no further than Simon Hudson and his team.

Milen, initially came as I had a leak in my ensuit where the tiles had lost their grout. He was very honest in giving me advice, and regrouted at a very reasonable price. He then came a month later to remove the tiles in the shower and replace the plaster protection board, then retiled. He purchased all the products and gave me advice on the most valuable sustainable tiles. The work was carried out a to very high level, I would most definitely hire Milen in the future, and highly recommend him.

We hired them to do a couple of specific jobs and ended up keeping them for the whole project giving them a great deal more to do. We will keep using them on other projects and we have no hesitation in recommending them. Regardless of the size of the project, they will rise to the challenge.
