Extensions- 29 Sep 2025
Our job started out as a small kitchen extension and shower/utility room but grew to also include fitting of a new kitchen, new kitchen ceiling, new double glazed windows to back of house, new garden wall approximately 50ft long and 5ft high and insulation to two internal bedroom walls. Rob and his team are extremely versatile and very approachable. I would certainly recommend them and we are hoping to have some more double glazing work done in the near future.

What to ask a Blackwood extension builder before hiring?

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

An extension builder in Blackwood 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 Blackwood 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 Blackwood?

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 Blackwood extension builder’s ability to deliver a result that meets your expectations.
