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- 27 Mar 2023
I’ve been left with the whole back of my house open and exposed to the elements. The builders have just packed up and gone. I’m getting no response from the builder Stuart. I don’t believe my house is structurally sound as the acrow props have been removed when the work hasn’t been finished.

Groundwork & Foundations- 6 Mar 2021
Harry and his team attended a trenching job for me today. Upon arrival his expertise was instantly apparent. He offered advice on how to complete the job correctly and his lads worked hard. We employ many sub contractors and is hard to find one who is punctual, attentive and knowledgeable. Harry and his team are all of the above and i will be using him again for future projects. I would not hesitate to recommend him and his team to anyone !!

Firoj and his team renovated a bathroom for me in March 2015. He gave me a fixed cost for his labour and what turned out to be a very accurate estimated cost for all the parts/materials at the outset. He also gave me a completion time of 9 days with 1 extra day for 'spillovers' and 'unforseen delays'. He finished the job at exactly 9 days and still came around on the 10th day to see how everything was working. The quality of his work was excellent, to say the least. He attention to detail was admirable, as was his commitment to delivering a finished product that would last several years. This focus on detail and longevity is something that really sets Firoj apart from other builders, who often see such jobs as just another task to be completed before moving onto the next job. I have no hesitation in recommending him. Several months later my bathroom still looks great and everything works.
