Landscaping- 4 Jun 2021
The works were to remove entirely all the aggressive bamboo rhizomes/roots and growth from a small, confined rear garden area ca 4m x 2m which had encroached from a neighbour, and replace with topsoil. Branden carefully scoped the work on site, and devised a safe working plan/method to reduce/eliminate risk damage could occur to the neighbour's ageing, delicate fence asset, or to the property's sensitive garden facias/walls. The works were carried out over two days on his recommendation to eliminate the risks. Branden always communicated clearly as required with myself and the owner of the property, was price very competitive and good value for money, and Branden and his co-worker worked efficiently and carefully at this awkward job. Many thanks. SDG.

Loft Conversion- 1 Nov 2024
Andy and his team have been faultless on our project. Communication has been exceptional, keeping us updated throughout. As with any project, timelines can move around, but Andy ensured we were always fully up to speed of what was coming next, with a a view of what would be coming down the line. We couldn't be more happy with the work that has been completed. Andy has a great attention to detail and a very high standard of workmanship along with an exemplary work ethic. Finding a good honest builder can often be a challenge, but i have no hesitation in recommending Andy and his team. A pleasure to be a client of his.

Landscaping- 12 Jul 2026
We are really pleased with the work Bob did in our garden. He was reliable, hardworking and easy to deal with throughout the project. He always left the site neat and tidy at the end of the day. Working from a design we had prepared, with guidance from us along the way, Bob built the garden walls using reclaimed bricks. He also laid the patio, path and terraced area with porcelain tiles. The design wasn't straightforward, with several curved walls and a winding path, but he took great care setting out, he has a real talent with the brickwork. The finished walls look fantastic and have completely changed the feel of the garden. We're very happy with the end result and wouldn't hesitate to recommend Bob to anyone looking for a reliable, skilled builder.

What to ask a Avon extension builder before hiring?

Before hiring an extension builder in Avon or extension building company in Avon, 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 Avon?

An extension builder in Avon 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 Avon 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 Avon?

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 Avon 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 Avon 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.

If you still have questions about the professional you are looking to hire, we have a full detailed guide on hiring the right builder here.
