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 project was to construct a 15m2 extension to our rear lounge on the ground floor plus a 4m2 extension to the bathroom on the first floor. This involved foundations, walls and roof tiling in addition to the installation of a 5m long RSJ to support the first floor bedroom. Jamie was selected because of his recent training and apparent enthusiasm. He planned and carried out the work very well. Problems when encountered were discussed and resolved with professionalism and enthusiasm. The resulting work has been completed to a high standard and I am well satisfied with the result. The time taken was as planned, he worked on a daily rate which was to my budget. Jamie' strengths are a good basic knowledge of the building regulations, good communication skills with other workers, suppliers and inspectors and excellent basic brick laying skills with a eye for dimensional regularity and excellent final appearance. I would strongly recommend this young and enthusiastic tradesman for any similar project work involving use of his excellent bricklaying skills.

Extensions- 14 Nov 2017
Darren and his team have been fantastic from day one. He's the builder you always hope that you get and that you will forevermore be recommending him to friends and family. Not only has he completed all the building work we've requested but he was so kind, considerate and tidy while doing it. He stays in touch, explains everything he'll be doing in detail and charges a very reasonable day rate - especially for the quality of work he provides. He's also available at short notice (or was for us) when we had an emergency situation with a neighbours home. I just can't recommend him highly enough. The only thing I fear is that he'll become so busy from me recommending him that he won't have time to come back and do some additional building work we now want!

He was very accommodating, helping to find solutions to make jobs work, and always to the highest standard. He left the garden beautifully tidy at the end of each working day. He has transformed my garden and I can't praise him enough. He is friendly and interesting to talk to and I will absolutely recommend him to anybody.

Guttering- 9 May 2018
Absolutely fantastic job. Worked like a trooper in all weathers. Nothing was too much Trouble and the work has been finished to a very high standard. Cleared up after himself each evening and worked through into the evenings often. Even the rain did not put him off and carried on working soaked through. If you are looking for a true expert for finlock guttering removal or replacement. Jason Shaw is your man. We had all concrete guttering around the bungalow removed and also removed from inside the conservatory. He made sure all openings were securely covered , taped up so we had no dust in rest of the house. We can highly recommend him .

Extensions- 17 Jan 2023
I engaged HJ Developments in September 2022 and as we have never had any major building work done before we were nervous about engaging and committing to spending a significant amount of money with people we didn't know. I went through MyBuilder.com and had 3 quotes HJ were not the cheapest but I really liked the way Harry communicated with us and nothing seemed a problem for him, and we asked him to return a couple of times to discuss various aspects and we also went to see a previous extension he had done and spoke with the owners about how they felt the job had gone so we eventually engaged him for the work. The team always arrived on time, were very tidy in their work and came in on budget, and have done an amazing job. Like with all big jobs, there were changes throughout (instigated usually by me) but there was never a problem, only a solution with costs discussed along the way so we knew where we were with the budget and could make a decision to accept the changes or not and we couldn't be happier with the end result. If you want a reliable, skilled team who will help and advise and be a joy to be around while they are working in your home, then you won't go wrong with Harry, Henry, and the team.
