Extension Builder in Upper Walthamstow
I have had the privilege of working on a 260-year-old Grade Listed building in Islington, London, under the close supervision of conservation inspectors. This project required a careful balance of tradition and innovation — I combined the use of modern machinery externally with traditional, delicate methods internally to ensure the building remained completely scratch-free. My experience has given me a deep respect for heritage projects as well as the skills to deliver high-quality results on modern refurbishments.

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.

Bathroom Fitting- 7 Jul 2026
This guy don’t know what he doing. Didn’t know the job and no proper knowledge about the work. When he couldn’t do it sold us to another crook. The other person didn’t do work properly and left the bathroom unfunctional after three months. Very bad experience and they took more money when they buy materials. Its disaster

Bricklaying- 16 Dec 2021
I'm very pleased with the repair that Jack carried out on my garden wall. Even though it was a small job he took the time to do it properly and ensured the bricks that had fallen down were put back straight. It started raining a little on the day causing the cement to run. Jack returned a couple of days later to tidy it up like he said he would. On inspecting the wall today I noticed that the cement on the bricks on the inside of the wall did not look as neat as how it looks on the outside of the wall. Maybe the rain caused the cement to run too much, I don't know. Overall I am pleased though and I've asked Jack to quote for another job.
