Conversions - General- 12 Aug 2022
I hired HM construction for installing a built in cupboard in a bedroom to my specification. The team was able to knock down an internal wall, make good another wall and install an excellent built in cupboard. I am very happy with the outcome, it’s a highly professional job that has transformed the bedroom. Of the back of this I asked the team to install a porcelain tile patio, new turf and convert an outside shed into an Office space. They completed the work in just over 3 weeks again to an excellent finish and very reasonably priced. They ensured the site remained and clean at all times and kept me informed throughout the process. Very trustworthy and highly recommended constructors.

Conversions - General- 7 Nov 2016
External Works and Repairs on Large House for Freeholder We had hired Chiro to complete External Works and Repairs on the Exterior of a building that comprised 2 flats on behalf of the Freeholder. From the outset Octavian and his crew were very professional to deal with in terms of negotiating the price, start date and the works to be completed. The project involved repairing brickwork, roof tiles, ridge tiles, parapet walls, pointing, facia, plaster work, fixing windows/sills and finally sanding and painting etc and required a comprehensive repair of the exterior of the building. Much of the work was quite intricate and required careful repair of damaged areas and often coming up with creative solutions to get a good finish. The workmanship and attention to detail was very impressive and even involved them doing online research to find an alternative to old ridge tiles that were no longer available. Any issues or additional requests that arose were favourably received and dealt with immediately. The project started and was completed on the agreed dates and the site was left clean and looking well. Overall I would highly recommend Octavian and his crew to other clients.

Almed and his team came over to see the two bungalows and gave me a quote and was more reasonable than other quotes I had previously. Almed started the job and stated exactly what he was going to do from the beginning to the end of the job. He is a very professional and knowledgeable person and he and his team did a outstanding plastering job on my two bungalows and I’m very happy with the job and will highly recommend him for future projects.

Isaac did a wonderful job converting our old conservatory into a wet room and storage. He takes pride in his work, is very considerate, went above and beyond his duty to help us and accommodate us. He is very reliable, trustworthy and I would recommend him to anyone. Thank you so much Isaac for treating our home as yours but more than that thank you for coming especially to help my husband when he had fallen on your day off.
