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- 12 Apr 2025
We met many different builders before making our decision to go with Balti property services. The deciding factor was Jason's clear knowledge and eye for detail. Their price reasonable and they are willing to negotiate to help fit your budget. They managed to get the job completed within the time agreed to a very high standard. The team of workers are very competent and friendly, they turn up on time and leave the property safe when they leave ate the end of each day. I am a project manager for high end Audio-Visual installs, so you have to be good to impress me, but this company did, so it's a 5 star from me.

Handyman- 6 Jan 2026
Firstly, I havent used mybuilder in years, and I hired Zaim hoping for a good job on our dining chairs. I can safely say I was very suprised. He did an excellent job. From the moment we talked he had great communication, he was timely and said he would call 30 mins before arrival which he did, he spent time fixing the legs of the chairs as if he were doing the work in his own home. He is also not afraid of letting you watch him work, he has nothing to hide and is genuinely a nice person. He wants to do a good job and doesn't leave until the room is in the condition it was in before he came, he even hoovered up afterwards. Zaim was professional, calm and knowledgeable. Some people do a rush job, but you could see he wanted to do a job that was good, even redoing work because he wasn't happy with it. A solid job. Would certainly recommend.
