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.

Extensions- 17 May 2018
Julian is a genuine person and a highly recommended builder.The price he quotes is the price you pay, the timescale he gives you is spot on , weather permitting.His pricing is very competitive without compromising on quality. Thanks to Julian and his team I now have a well built, beautiful double garage along with a new dormer in one of the bedrooms carried out as an extra job by other members of his team. I would use this builder again and would highly recommend Julian to everyone that needs a honest, reliable and experienced builder.

What to ask a Cirencester extension builder before hiring?

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

An extension builder in Cirencester 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 Cirencester 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 Cirencester?

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 Cirencester 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 Cirencester 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.
