Damp Proofing- 12 Jan 2016
Tony and his team were superb. They assessed the work, drew up clear plans so I understood what the job entailed and completed the interior work to a very high standard. Every day they swept and mopped to reduce my workload and for the first time in my experience of builders, every last scrap of rubble was removed. A very happy customer; cannot recommend them highly enough.

What to ask a Mountain Ash extension builder before hiring?

Before hiring an extension builder in Mountain Ash or extension building company in Mountain Ash, 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 Mountain Ash?

An extension builder in Mountain Ash 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?

What experience do you have with similar extensions in Mountain Ash?

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