Bricklaying- 28 Jan 2025
I recently hired A1&PM to carry out structural repairs on my house, including replacing window lintels and providing complex temporary works to support the structure during the repairs. They also patched plaster, skimmed a wall, rendered, and repointed an external wall. From start to finish, the team was professional and reliable, turning up on time with all the necessary tools and materials. Protecting carpets and covering furniture. Their knowledge and expertise were evident throughout, and they completed the work exactly as promised. The pricing was very competitive, and the quality of the work exceeded my expectations. I was initially sceptical due to some past review, but my experience couldn't have been better. I would definitely use their services again and wouldn't hesitate to recommend them to others. Fantastic work—thank you!

Extensions- 8 Mar 2026
We had a fantastic experience with Xtend London Ltd and couldn’t be happier with the work carried out. The whole project was handled very professionally from start to finish. The team worked at a great pace without ever compromising on quality, and the price was very fair for the standard of work delivered. Throughout the process they gave us really helpful advice and guidance, which made everything much easier and ensured the best decisions were made along the way. Communication was also excellent – whenever the team wasn’t on site, messages and questions were answered very quickly. A special thank you to Lucas, Dean, Eldi and the rest of the team for all their hard work and dedication. It’s clear they take a lot of pride in what they do. We would absolutely recommend Xtend London Ltd to anyone looking for a reliable and professional building company, and we would definitely use them again in the future.

Restoration & Refurbishment- 16 May 2021
TLC have completed the first phase of the project which has involved a complete renovation and upgrade of the kitchen, bathroom, and rear garden area. A new contemporary staircase has also been fitted. The work has been completed well ahead of schedule, and this is testament to the planning and coordination skills provided by TLC. All of the work has been completed to a very high standard, and a great deal of care has been taken to ensure the minimum disruption to the local residents. We are extremely grateful for the advice and support provided to us leading up to the restoration work and whilst the restoration was underway, and we are absolutely delighted with the final results. Our house has been transformed into a contemporary family home. Many thanks to Bradley, Paul, and the rest of the team at TLC.

What a great experience we had with Louis. He is honest and gets the job done efficiently with great attention to detail. He did such a good job with our terrace. We had some problems that really needed a professional solution and Louis planned and executed it brilliantly. Instead of looking for excuses for things that could be a problem Louis had a great solution for everything we came across and was positive the whole time. Would highly recommend Louis, we already have him booked in for more jobs.

Restoration & Refurbishment- 3 Jun 2021
Enrico pulled in a great team to refurbish my bathroom. It wasn't a straighforward suite swap out as I added a window, switched from an electric to plumbed shower, properly plumbed in the sink and changed the orientation of the shower and bath. Enrico took all of the stress out of ordering and receiving all the different elements, he added in some great suggestions of final touches and kept close to all aspects of the project until I was fully satisfied with clear timings and payment plan etc. on top. It's an old house and there were curve balls from time to time but Enrico and the team took them in their stride and made it a great experience. I'm totally thrilled with the end result.

I looked at 5 quotes and was so happy to have chosen Elvis and his highly experienced team. They did an excellent job of building a new 11sq meter garden rear extension. This was a bit complicated project because it’s a listed house. Elvis and his team were hardworking, always responsive and came up with great solutions when necessary. I am very pleased with the high quality end result. I would use them again and can't recommend them enough! Great job done
