Landscaping- 4 Oct 2024
One word to define this 'company' COWBOY builders. Numerous issues one after another. Had to get 2nd/3rd opinion on their work to make sure I wasn't being fobbed off. Conducted loads of research which meant left being uneasy especially as a large chunk of payment was made after only 1 day of work when in fact payment was due end of completion. 1- Underestimating material costs 2- Slabs off the walkway coming loose within 2 months of being put down 3- Ignoring attempts of rectifying the flawed job 4- walkway was meant to be clear of grass and strictly shingles but grass/weed still appearing. 5- Forgot to state ground levels would be raised then creating a lie saying I had been told 6- denying and ignoring the obvious Wouldn't trust the reviews being left here and definitely wouldn't use or recommend them to anyone. Have decided to give up on trying to get them to fix their shoddy job and find someone else to fix their mess Correction - you was aware & agreed with mat delivery

HOSSBER LIMITED

Extension Builder in West Brompton
I started working in construction sites as cleaner back in 2005 and then joined a company that was carrying out commercial renovation for licenced premises, listed buildings and offices and then moved to other companies that were carrying out domestic works, such as loft conversions, extension, renovation and everything in between. I would like to think of our company as a 1 stop shop to all your construction needs, from planning to costing, from project managing to building and delivering.

Kitchen Fitting- 31 Jul 2019
To say Nick is just a kitchen fitter isn’t doing his work justice, he’s a fantastic project manager and craftsmen as well. When we first met Nick he took 2 hours of his time running through all the options which was when we realised we were actually quite clueless! Although we hadn’t hired him at this point his advice was invaluable. We assumed this would mean Nick’s professionalism would mean he would be very expensive, this was not the case and he was actually a little cheaper than the other parties who quoted. Once Nick started it became apparent that he and his assistant Chow to great pride in their work and worked hard to get the job finished as quickly as possible to the highest standard. They left the site spotless at the end of each day. The result is a fantastic kitchen and flooring which we are extremely happy with. We are already thinking about the next renovation piece in our home and would love to use Nick again. Thanks Nick! Niall & Hannah
