Extensions- 4 Nov 2023
Overall me and my husband are very satisfied with the workmanship and with the final result of our my fake cladded garage door with the new aluminium framed window. The original garage was converted into a habitable room 7 years ago with only a rooflight to bring light into the room, which is now my husband's office and this new window will make a lot of difference therefore we are very happy with the finished work. The work was done very quickly, the builders turned up on time and they were very efficient and helpful, they took particular care when installing the composite slatted panels to the marine plywood. The main contractor Pawel Speiwak also came on site to inspect the works during construction. The quote was also very competetive, a good value for money. I would definetely use them again for any future work in my house and recommend them to other people.

Freddie, Kaz and Dan are a great team. I felt they were friendly and professional throughout. Any slight niggles were discussed and solutions found, quickly and professionally. They were respectful and went out of their way to get on with all the neighbours. Over all I would say they are a team of very nice people, who care about what they do and take pride in achieving the result their clients are after.

Bathroom Fitting- 2 Mar 2026
I can’t recommend him highly enough, in just three days, he identified and resolved my bathroom leak that could easily have become a much bigger issue. He took the time to thoroughly investigate where the water was coming from, clearly explained his findings and advised on the most sensible next steps before carrying out the work. From start to finish, his work ethic was exceptional. He arrived promptly at 8am every day and worked through until 6:00pm without a single complaint, no matter how demanding or time-consuming the job became. His efficiency was impressive but what stood out even more was the quality of the finish - the bathroom now looks brand new again. Professional, hardworking and meticulous in his standards, he delivered outstanding results in a very short timeframe. I wouldn’t hesitate to use him again or recommend him to anyone needing reliable, high-quality building work

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

An extension builder in Waltham Forest 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 Waltham Forest 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 Waltham Forest?

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