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.

Bricklaying- 5 Oct 2018
Thank you Patrick the job was completed professionally and on time. Patrick's work went above and beyond my expectations of how excellent the rebuild of a wall and installation of a window would look when completed. Patrick and his team arrived on time. I was kept informed of progress each day and Patrick and his team worked constantly throughout the day. They tidied up each day and on completion of the job. Patrick is very skilful and has great vision of how the work he does should look when finished. I would invite Patrick and his team to complete any future jobs as he is reliable, trustworthy and have restored my faith in the building trade after other no so nice experiences. Thanks once again for an excellent job, I am so pleased with the service received.

I have been in the building trade since 1981 and have developed my skills to incorporate carpentry, plastering, drainage and bricklaying. I enjoy all aspects of the building trade from groundwork to finish, I especially like cutting a roof as this is an enjoyable phase of the build. I am a clean and tidy worker and a perfectionist and this is reflected in my high standard of work. I also pride myself on my good working relationships with clients.

Having purchased our new build property thru Kingsleigh Homes Ltd, we would like to say how happy and impressed we are with Shawn and his work colleagues on producing an absolute stunning house. After initial contact with Shawn and going thru the plans and ideas we felt confident and reassured by Shawn’s knowledge and expertise. Nothing was too much trouble when we changed our minds about certain specifications during the build. It was very easy to approach him and get things done. Everything was done with high spec and professionally. Shawn’s and Kingsleigh Homes work speaks for itself. Very high standards created by him. Very pleased with the end product.
