Extensions- 21 Dec 2017
Dishonest from the start. Every excuse in the builders handbook (and new ones). Lazy (they like to work 10-1 and never a full week). Never finished the 2 month project after 6 months - walked away

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

An extension builder in Coulsdon 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.

What experience do you have with similar extensions in Coulsdon?

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