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.

Extensions- 28 Sep 2018
Johnny was very nice to deal with. When there were problems they were quick to find ways to rectify them. They started at short notice& finished on time which I was very impressive. We got a no. of quotes,Johnny was middle of the range but with a better level of service than others. Johnny was very open about when things might cost more &gave us the option if we wanted to proceed. A few things to note: -this was our 1st experience of any building work &we should have remembered they are builders, not designers -we both work long hours &so most days didn't see the team to get an update or brief them. This meant a few things were missed or miscommunicated - while most of the team were lovely the electrician used was horrible to deal with. He got very cross about requested changes, didn't deliver everything requested &just did silly things like putting in a light switch with 2buttons where there was only one Light or hanging lights incredibly low when we had given measurements of where we wanted them - we got Johnny's team to build some extra storage for us which on the whole was fine but some things weren't centred or for example the wine rack they built was wonky Overall, it was a good experience and we would recommend them but would suggest be home to oversee the work more than once a week (must be true of any building work!) and get your own electrician. Very happy to talk to people and give references-the house looks great now.

Windows & Doors (uPVC & Metal)- 25 Apr 2026
We found Marian from CM Fixing after the suppliers recommended fitter proved unresponsive and we are so pleased we did. We have found dealing with Marian an absolute pleasure - really responsive communication, excellent price and he has done a fantastic job for us today. They arrived promptly at 8am and fitted our new doors with no fuss and lots of care and it’s all looking amazing. I would recommend Marian and his team to anyone considering an installation.
