Extensions- 6 Aug 2020
I’ve lost count of how many times we’ve said how lucky we were that we chose Bryan and his team to build our kitchen extension. The team went above and beyond to ensure as little disruption as possible, as we remained living at home whilst the work took place. During this difficult time, Bryan did everything possible to source the materials required to finish our build before our baby arrived and some how he managed it! His team were really friendly and the family miss having them around. They always tidied up after themselves before leaving too. What we thought was going to be a stressful time was in-fact the opposite. Bryan managed the whole process, kept us updated throughout and made sure the build remained on budget. The level of finish is of the highest standard, better than we could have imagined and I can’t recommend Concept enough. We will undoubtedly be using them again for work in the future. Thanks again to Bryan and his Team.

What to ask a Dunmow extension builder before hiring?

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

An extension builder in Dunmow 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 Dunmow 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 Dunmow?

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