Extensions- 17 Aug 2020
Justin did a great job on our small extension and kitchen knock through. He saved our backs after our original builder had let us down and was able to take on the project quickly for us. We heard back from him almost immediately after coming to look at the job and work started soon after. Justin and Craig worked very hard to get the work done and despite our old wonky house throwing in some extra challenges along they way (thanks Victorian builders!), the job was done within the timescale and for a good price. Justin kept us in the loop throughout the project, making sure we were happy with everything and communication was great. We were able to discuss any questions we had and Justin even gave us advice on other parts of our house renovations that we are undertaking ourselves. Justin and Craig were very reliable and showed up when they said they would. They are also probably the most respectful tradesmen we've ever encountered! Always being careful to tidy up after themselves and going above and beyond to keep disruption and mess to a minimum. We would not hesitate to recommend Justin or use his services again in future!

Decking- 6 Sep 2020
I am very pleased with the quality of work Gordon completed on my composite decking. He was here for three days and worked tirelessly through a very rainy afternoon. I found his communication to be excellent, keeping me up to date on materials ordered and a timescale for work to be completed. Professional, honest and friendly. I’d definitely recommend him to friends and family.

I employed Evans Contracts to build a pair of semi detached 3 bed 2 bath houses. Although a tight build they coped well and produced two very high quality finished houses. Bad weather slowed the project a little. Budget a little over but there was additional work done ie landscaping and tiling that was not in the original price. Alan is a good communicator that knows his trade inside and out. Highly recommended.

What to ask a Bristol extension builder before hiring?

What qualifications and experience do you have as an extension builder in Bristol?

An extension builder in Bristol should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

Will my home extension meet all building regulations and planning requirements?

Your Bristol extension builder should ensure the project complies with Building Regulations and, where necessary, handle or assist with planning permissions. Ask how they manage building control inspections and what documentation you’ll receive once the project is complete.

What experience do you have with similar extensions in Bristol?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Bristol extension builder’s ability to deliver a result that meets your expectations.

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Bristol extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
