Extensions- 28 Oct 2018
We appointed HWB to carry out a full refurbishment on our house, this involved re-gutting the interior and building an extension and loft conversion plus some landscaping in the garden. We spoke to many builders but finally appointed HWB based on their previous projects and professionalism. Appointing builders for any work is always difficult however we are delighted that we went with HWB. Throughout the project they have demonstrated high levels of professionalism, were very organised and worked to very high standards. They were collaborative throughout the whole project and kept us informed at every stage. As the project developed there were some changes made and HWB were flexible and open to new instructions made by us, as well as giving us valuable advice. Farag, Ayoub and the HWB team were always available to answer any questions and provided us with constant feedback on progress as well as identify new solutions to aid the development. They have a great team of workers who work to a high standard and are supervised throughout the project. We made the right decision going with HWB Construction and have no hesitation in recommending them.

Extensions- 13 Dec 2021
GARDEN ROOM - instead of extending the conservatory, we decided to build a garden room instead. Ionut took the lead with the design and structure, and I’m over the moon with the results. A great experience from start to finish - Ionut was a pleasure to deal - friendly, professional and courteous. Would highly recommend.

Extensions- 30 Dec 2021
Its been a pleasure having Albi and his team build our extenstion. Excellent job done (we had a 32 sq m extension for a new kitchen/dining room and the build was seamless). Good workmanship and genuinely easy to interact with. Albi kept to the timelines, offered good suggestions and delivered excellently. Albi and his team are reliable and provided a competitive fair price. They would be here early (7.30 - 5) 6 days a week and were a genuine pleasure to deal with. They were neat (even covering our drive with mdf panels to protect it from rubble) and then pressure washing it clean at the end. Works included Foundations Construction work Skylights Roof structure and roofing Windows/Bi fold door Exterior render Insulation Woodwork - doors, architraves, skirting Plumbing Electrics Plastering Paint Flooring (wood & tile) Tiling Installing kitchen

Insulation- 14 Feb 2023
I placed an add in mybuilder.com to have my house fully insulated and received many replies including one from Sergiu. After meeting him I felt he was the best placed person to carry out the work as he was the most knowledgeable and seemed to know all about the various types of insulation and which one I needed for my home. He fully explained the procedure from start to finish was always on time and tidied up at the end of each day.His work is second to none and the price was very very competitive in fact much less then the big companies were asking.I am extremely happy with the job and the standard of finish. Sergiu is very police professional and trustworthy and I would have no hesitation in recommending him to anyone on here to carry out work in your home.

Bricklaying- 19 Apr 2016
We have always found it a problem trying to match the correct tradesman to any work we have needed doing, so much so that many jobs have been left undone. You either end up with a personality clash, or just plain bad workmanship, well not this time. The entire process was a joy from start to finish, from the initial quoting process, to the completion and the standard of work was exemplary. Nothing seemed to be a problem for them and they were very pleasant to have around. We are busy drawing up a fresh list of jobs we need doing and would certainly thoroughly recommend them. If you have had any bad experiences in the past, give them a try, you will be very satisfied.

Bathroom Fitting- 20 Jan 2023
We highly recommend Mario & his team. They fitted a new kitchen & bathroom to a really high standard within a short, timeframe. They work hard, are friendly, professional & honest, my neighbour even commented on how considerate they were! Upon first meeting Mario we were impressed by how organised he was. He arrived on time with the description we’d posted on my builder & went through it methodically. We had A LOT of questions! He answered all of them & didn’t rush us. We received a competitive quote within a day as promised. It included everything we discussed & he quickly answered our follow up questions. We wanted an accurate idea of the cost of electrical work & Mario arranged for his electrician to come & inspect/quote before we’d appointed Mario the job. Our kitchen & bathroom is complicated, with lots of difficult angles. Damp, unlevel floor, unlevel windows, a low ceiling were uncovered in the bathroom. Mario did well to identify solutions, giving us expert advice. Pipes were neatly chased into the wall. Underfloor heating & LVT, tiling, grouting & painting all done to a very professional finish. He kept us informed of progress, checked our preferences & was patient when we had supply delays, finding ways to ensure the job finished on time enabling us to move from our temporary accommodation back home in time for Christmas. He promptly fixed some minor issues after the job finished. We highly recommend Mario & would use him again.

Restoration & Refurbishment- 8 Jun 2020
Kamil and his tiler have been excellent. He was able to do the work at short notice, he always turned up on time and stuck to his quote. The quality of the work is excellent with special mention of the tiling which would probably win a competition! Kamil remedied minor problems that occurred as the work was in progress ensuring that the completed work was first rate. I will certainly use Kamil again and have no hesitation in recommending him to others.
