New extension, kitchen, shower room, flooring, fiber glass roof, roof light, new electrics, plumbing, boiler installation, removal of chimney, rear patio, soakaway, painting and decorating Satnam has exceeded our expectations in carrying out the complete job to our satisfaction within the agreed time to a very high standard. We are extremely pleased with his work. Satnam helped us select good quality products from suppliers for much less cost than if we were to source them ourselves. He was honest, courteous, professional, flexible, open to changes and made suggestions to improve the overall look. He even passed on his builders' discounts to us. We highly recommend this ambitious young builder who has excelled in the trade. We wish Satnam and his team the very best.

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 Woolwich extension builder before hiring?

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

An extension builder in Woolwich 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 Woolwich 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 Woolwich?

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 Woolwich 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 Woolwich 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.
