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.

Restoration & Refurbishment- 19 Aug 2024
Albo Dream Ltd - this company is an absolute disaster. Lack of skills and experience, very sloppy work, unable to independently solve problems that arise during the job. They don't care about securing the worksite to avoid damage, which exposed us to additional costs, and after finishing the work, they don't clean up after themselves, leaving a mess. They didn't complete the renovation despite promising to do so and being paid for it. If you don't want to have major problems, steer clear of this company.

Electrical- 23 May 2019
C Hanlon have just completed the full rewire of the property and I am more than delighted with the quality of workmanship. Mark came out and surveyed / priced the job last week and whilst it was not the cheapest quote that I had, I progressed based on the fact that they were a local company who were able to start immediately and complete it quickly to a high standard. The job took only 2 days to complete and John, the Electrical Manager kept me fully informed throughout. I would have no hesitation on using C Hanlon again or recommending them to friends or family.

Insulation- 2 Mar 2022
Jonny is excellent, a real pleasure to deal with, intelligent and very capable. The work was just as l had hoped, good quality, thpight through, efficiently carried out and reasonably priced. I am only sorry l have not had the chance to met him, as l was never on site. But there will be more work to be done, and l will certainly ask him first. My daughter was on site and was impressed by his thoroughness and extensively researched investigations befote he gave us areport and a quote, all very helpful for me 150 miles away. He understood our aims and was very sympathetic and helpful, and even recommended an EPC assessor to complete the project, which has been a total success.

We employed Steve and his colleagues to do a extension above our garage plus extend the back of the house and build an Orangerie. The quality of work was excellent and I certainly have no complaints. It was slightly over schedule but bad weather paid a part in that at the early stages. However, the amount we paid at completion was exactly what we had been quoted at the start. It is a 4 man team and all of them are very polite and helpful and very willing to do anything extra that I asked. What I particularly liked was that there was usually 2 or 3 of them on site at any one time and not a day passed when there wasn't at least one. I know from friends who have had other builders in that this seems to be rare. When planning for our project we were very worried about choosing the builders due to so many horror stories. Steve provided me with 4 references, who I phoned and all of them had nothing but positives to say. As an added bonus of all the quotes we received they were the cheapest!! I would strongly recommend them and already have to my friends.

Bathroom Fitting- 3 Nov 2017
Couldn't be happier with our new bathrooms. Jack was the perfect choice for our project and helped us make our plans even better by providing honest and professional advice. The team he recommended are also second to none and they have worked tirelessly to achieve superior results to our expectations. The project was clearly mapped out for us so we understood in what order what was happening, and when we met a challenge, Jack provided a variety of options that we could chose from. Would definitely recommend Jack for your project.

Barratt Building and Joinery is a sole trader and has been going for the last 4 years. Prior to this we used to sub-contract for a number of different builders in the Cheshire area. We decided to set up our own business so we could offer our services to a personal level rather than just sub contractor. No job is too big or too small. We undertake anything from extensions to small guttering jobs or even smaller detail jobs such as changing locks.
