Driveways (Paved & Loose)- 22 Oct 2025
Gent was quick to provide an accurate estimate and to start the job. He was polite and helpful throughout the 5 days it took (we ended up extending the driveway, not only repairing it) and worked very hard. He took care and made sure every detail was right regardless of how time consuming that was. It felt like he was working in his own house! I will definitely work with him again (I have already booked him for the next job) and would recommend to anyone.

Landscaping- 14 May 2026
So happy with our revamped back garden and so impressed with Peter, George and Tommy, who worked so hard through some pretty dodgy weather. Peters quote was very competitive and made a mockery of some extortionate quotes I was given. He and his team were able to start the job promptly. They removed old turf and slabs, extended an old patio and built a new one. The job was completed by returfing the remaining grass area. They completed the work quickly and produced a quality end product. Peter was very flexible and dealt with us changing our minds 3 or 4 times in a very calm manner. They worked incredibly hard but made sure that they left everywhere clean and tidy each day. We thoroughly recommend their work and wouldn't hesitate to use them again

FANTASTIC service, will definitely use Lucian and his team again. They were quick to respond, quoted straight away, could start quickly and did a fantastic job. We totally trusted the team, they were respectful with our house and after discussing the final snag list with us they left everything immaculate. We have many other refurbishment jobs to do to our house and will use this team again. Hard-working, polite, super responsive and they have left a really quality finish. We are delighted. Would highly recommend! Thank you Lucian and team!

Bricklaying- 24 Jul 2025
I recently hired Louis to build a new fence outside my home, and I couldn’t be more delighted with the results. From the moment he arrived, he was the epitome of professionalism—punctual, polite, and incredibly courteous. The quality of the brickwork is outstanding. Each brick is perfectly placed, the lines are crisp, and the finish is flawless. It’s clear Louis takes great pride in his craft, and his attention to detail is second to none. The fence has genuinely transformed the exterior of my house and added a real touch of elegance. Beyond the technical skills, Louis was a pleasure to have around—well mannered, respectful, and always happy to answer questions. He kept the area tidy, worked diligently, and made sure I was satisfied every step of the way. Highly recommended for anyone looking for top-notch bricklaying with a friendly face and a professional attitude. I’ll definitely be calling on Louis again for future projects!

Restoration & Refurbishment- 3 Apr 2016
Vidas and his team did a fantastic job with our property refurb project and I can't recommend him highly enough. He completely stripped out property back to brick and rebuilt if from the ground up. We had some quite particular requirements requiring the removal and creation of new partition walls and Vidas was able to accommodate and direct us in how we could address each requirement. We are very happy with the finish and have had many compliments from other tradesmen on the quality of the work. We did have some minor snagging after the project was complete but Vidas was very accommodating in coming back to rectify these issues. I would highly recommend Vidas and look forward to using him again in any future projects.

Extensions- 8 Apr 2023
I cannot thank Lee, Iain and Karl enough for their work on my mothers house which was left in an atrocious way from a cowboy builder who did an extension for her. These guys from the start to finish were wonderful. They helped us through a very difficult situation and completed the work required to a fantastic standard including a very complex roof re-structuring, including even replacing the main ridge beam and even getting in a steel beam, that should have been in place from day 1 of the build, after everything was completed without any problems. Got everything up to regs for us and worked through undoing basically a terrible and challenging build to get it right and safe without any issues or inconvenience to us. Always polite, cheerful, finding solutions, making sure we were all happy with every stage, honest, reliable, completed work in deadlines they set and communication was excellent. Very reasonable on prices and honest guys. I will not hesitate to use them again and I wish we had found them in the first place! Highly recommend, you are in safe hands with Maynard builders! It’s hard clearly to find trustworthy building companies but these guys are amazing and value their customers to the very end. Thank you so much Lee, Iain, Karl, Jamie and the whole team. All the best!

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

An extension builder in Plumstead 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 Plumstead 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 Plumstead?

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