Bathroom Fitting- 30 May 2022
Mohammed Huda and his builder were professional and quick to attend our job –– recommend! The communication was fast and professional. Mohammed provided a detailed quote (our job had to go through insurance) that is fair and transparent. The builder who came around, Jafa, was very respectful to our things. We were able to trust him from the get-go and had a peace of mind when he was working. He works incredibly hard and is methodical in his process (e.g. painting ceiling first, then walls, so to avoid splatter unevenness). They responded to our requests quickly and fixed things we weren't 100% happy with. The team finished the job ahead of time, and gave us tips for refurbishing in the future. Very happy and highly recommend!

Extensions- 7 Feb 2020
I had installpro put an extension on my kitchen by knocking a lean-to and extending into that space, also completed insulation and roofing on the new extension and existing roof, this involved building new external walls, damp course membranes, plastering, new cast iron radiators were plumbed in, new electrical circuits and sockets, tiling, skirting, painting, new sash window fitted, new guttering and fascia and even a fitted kitchen bench was made from scaffold boards, which came out really nice. Marek was very professional and everything was done in a timely manner, no waiting around once things were agreed on. Always early every morning and working full days, even one of his team worked a Saturday to stay on the timeline. The quality of the work was very good, I was impressed with the roofing, proper insulation was used throughout, at the side of the roof behind the fascia too and new lead flashing was finished properly. The team that worked here were very clean, always using proper dust sheets and cleaning up at the end of each day. At the end of the job, final touch ups were made after consultation, to make sure I was happy with everything and then Marek saw that a proper cleanup happened and everything was completed on time and on budget as outlined at the beginning. I can recommend Installpro, and I will use them again for future work on my property.

Restoration & Refurbishment- 21 Apr 2023
Marius accomplished a difficult work for my property. We had a heavy leak difficult to identify which required a couple of investigations. He finally gave me the price figure and estimated time to do the work and he managed to do it in a successful way all the way through. He changed all electric work under the stairs, completely replaced new joists, plywood and engineering floor on top. He changed the damaged staircase, solve the leak problem without causing big damage. Thank you for your business. Will definitely hire again for my loft conversion. Would highly recommend!!! Thank you for your business!
