I have used LKK Builders on two of my projects, and I couldn’t be happier with their work. The most recent one was a full three-bedroom house refurbishment, which included fitting a brand new kitchen, installing a new bathroom, complete rewiring, replastering and painting the entire house, and laying new flooring and carpets throughout. LKK Builders got everything sorted, including arranging the electrician for the full house rewiring and a gas safety engineer to check all gas appliances and service the boiler. All materials were on site on time, and there were absolutely no delays. Communication was always quick and clear, and the team were very professional and friendly throughout. The whole project ran seamlessly from start to finish, and I will definitely continue using LKK Builders for future projects. Highly recommended!

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

An extension builder in Harwich 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.

Your Harwich 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 Harwich?

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