Painting & Decorating- 14 Feb 2023
Edwart is polite, gave a competitive quote and got started straight away. He provided the materials and the workmanship is good enough. He and his team worked hard and stopped smoking in the house after I asked them not to.

Repointing- 10 Jun 2026
I tend to only leave a review if it’s someone/something that should be avoided or something outstanding. In this case I can’t recommend DW Brickwork enough and only wished I came across their services a few years back. This was a brick re-pointing job, but DW Brickwork were professional, attentive and excellent at communicating. Due to the weather the job took an extra day but the job was complete and carried out at every stage like it mattered. So this will be a contact I’ll have in my phone for the future. Highly recommend!

What to ask a Bexley extension builder before hiring?

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

An extension builder in Bexley 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 Bexley 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 Bexley?

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

How long will the extension take to complete?

Extension project timelines can vary depending on size, complexity, and weather. A typical single-storey extension might take around 8 - 12 weeks. Request a detailed schedule so you know what to expect and when key milestones will be reached.

Do you offer a guarantee for your work? Most Bexley extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
