An excellent job from start to finish. FORTIS were flexible with the garden design, created a new patio seating area and paths, improved the drainage, weeded horrendously overgrown shrub beds, levelled and returfed the lawn and created new flower beds. Also, while working on the garden, Peter and his team created me a new cloakroom from scratch, improved the storage and electrics in the garage and installed a fire door between the house and the garage. All this was achieved to a highly professional standard and I am delighted with the results. Peter is knowledgeable, adaptable and an excellent communicator. He and Sean were always where they said they would be, on time, and with a friendly laugh and a smile. Materials and other members of the team (electricians, gardeners, decorators, etc.) appeared when needed, as if by magic - so I know Peter's project management is good. I cannot recommend FORTIS C&M highly enough. Indeed I've already asked them to quote for three more jobs! I must remember to get in more biscuits though, eh Sean?!

Chris and his team completed a large ground floor extension to our 1930s bungalow, along with internal modifications. Chris was reliable and kept us informed about the progress of the build at all times. He was polite, helpful, trustworthy and a tidy worker. Living on site during the build it was really important to have good people around and everyone Chris bought to site also did a great job. We are really pleased with the end result and would recommend Chris for any building works! Would happily use him again.

Extensions- 28 Apr 2021
Our house has an extension at the back, built by previous owners as a Laundry Room. It was very badly constructed, draughty, rain came through the roof, the doors didn’t fit properly, and it had never been completely finished. We’d had several repairs done but decided in the end that the best thing would be to have it virtually demolished and rebuilt. Colin was one of the first to respond and came the next day to quote. I was happy with his suggestions for the replacement walls, doors, windows and roof, and the cost was in the region that I had anticipated. Work began a couple of weeks later. Simon and Jad worked particularly hard on the walls, windows, doors and ceiling joists; Mark did a good job on the EPDM roof covering, and Sam plastered the walls expertly, while Duncan did all the finishing touches, such as trims. There were a few delays and occasionally unexpected problems arose, but Colin was quickly able to say how they could be solved. The result is that we now have a much smarter Laundry Room…and we assume it is watertight!

Bricklaying- 30 Aug 2022
I feel compelled to write a raving review, having used many tradesmen in the past and been somewhat dissatisfied and disappointed due to incompetences followed up with ridiculous excuses. H.M.Brickwork have restored my faith in builders. The team of men were professional throughout, they took exceptional consideration for my garden when gaining access to the work site which is awkward at best. The team have the right mind set and attitude, they work cleanly and efficiently. I have no problem in recommending H. M. Brickwork. A Coombes, Loxfield House, Buxted.

What experience do you have with similar extensions in Hailsham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Hailsham extension builder’s ability to deliver a result that meets your expectations.
