Conservatories- 14 Sep 2026
Had Bristol home improvements round to replace an old lean to conservatory. Jason came round to go through our options and then sent over a quote. We had a few more questions so he offered to come back to go through it with us again. Had excellent communication throughout the whole process. The work was completed in a week and the 2 men who done it were very polite and kept us informed of what was going on the whole time. They tidied everything up behind them and left no mess. The new conservatory looks lovely and has been completed to a very high standard. I would happily use them again in the future.

Extensions- 21 Jul 2021
Top Tip - Engage Andy to do your work! We were delighted with the work Andy and his team completed on this new extension. Andy was on site throughout the build. His and his teams experience with this sort of work ensured that there was always a solution for minor problems and the advice they offered on light/space/design was invaluable. Despite the general increase in costs and shortage of materials during this pandemic, Andy brought the whole project in on time and within the original budget. His team worked well together, were polite and friendly and ensured that they understood the requirements and level of finish we were trying to achieve. In short - on time, on budget and a quality job. Can't recommend him strongly enough.

What to ask a Coleford extension builder before hiring?

Before hiring an extension builder in Coleford or extension building company in Coleford, ask a few key questions to make sure you’re choosing the right professional for your home extension project.

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

An extension builder in Coleford 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 Coleford 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 Coleford?

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 Coleford 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 Coleford 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.
