Erick demonstrates remarkable thoroughness, reliability, and trustworthiness. His keen attention to detail is exceptional, and he leads a highly efficient team that promptly meets all demands and tasks. He successfully refurbished my entire house in Northampton, adhering to the projected timeline without any delays or setbacks. Throughout the project, he never dismissed any of my requests and fulfilled them all effortlessly. Erick is always easily accessible, promptly responding to calls and messages. I have enthusiastically recommended him to several of my friends, all of whom are immensely satisfied and grateful for his services. Furthermore, his pricing is fair and reasonable, leaving me extremely pleased with the quality of his work.

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.

Carpentry- 7 Sep 2021
The cladding was due to start yesterday, Monday 6th of September. In the weekend, I was told they would come do a site visit on Monday instead of starting the job. They came on site yesterday morning and nothing was said about any issues. They said they would start the next day, Tuesday. I got a call at the end of the afternoon (around 5 pm) yesterday to be told suddenly that there are many problems; not levelled portions of frame (which can be easily rectified), no toilet on site (which they knew about - they knew also that the public toilet is only 50 m away), access problems which they also knew about ect... Suddenly a multitude of problems arised! They wanted more money. It is very obvious that they found another job somewhere. I would classify this sort of behaviour simply as not honest. Also expensive- I was quoted £4000 to clad a tiny first-floor(38 m2) . The overall cladding would be 75 m2 in total. Disappointing.

Extensions- 15 Aug 2018
100% RECOMMENDED Michelle and her partner measured up and competitively quoted within a short space of time. She was then very patient and supportive when unforeseen planning issues popped up and set the start date back by quite some time. Once building started, all questions were promptly answered by either the site manager or Michelle, both being available at all times. I was away for the duration of most of the job and it was very reassuring to know that I was leaving it all in capable and honest hands. The workers were very proficient and tidied up after themselves at end of each day. They also put in some very long hours at times to hasten the work. I was also impressed by the handling of unexpected problems during the building (mainly invasive tree stumps!). I am absolutely thrilled with the end result. High quality workmanship and a beautiful building which I am sure will last many years. I would certainly recommend them without a doubt.

I highly recommend William Haykal. We hired him to renovate our entire 2 bedroom, 2 bathrooms flat, he’s done the job in just 19 days and the end result is simply stunning. His attention to details, craftsmanship, and professionalism exceeded my expectations. From the initial consultation to the final touches, he made the process seamless and delivered outstanding results. I couldn't be happier with his work!

Extensions- 12 Jul 2021
Great company. Came round on a Sunday to look at the job and quote and were so totally honest, they told us they didn't think anything was required! They left a quote if we wanted them to take up the floor and explore further what we thought the issue was but said, in their opinion, nothing was required. How refreshingly honest. Great guys, great experience, thank you so much
