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

Extensions- 7 Mar 2026
Viktor is an excellent builder. He understands the needs of a complex job and mine was a huge renovation project. A side return and extension and full refurbishment of the house including the installation of 3 bathrooms, Kitchen, cupboards and much much more. It’s not quite finished yet but the house is transformed and the work was done incredibly fast, far faster than I had anticipated. I moved out for the duration but I was back in the house within 4 months. The language barrier made things a little harder than they might have been but we got by. If you have someone to project manage the job alongside Viktor I would suggest that but if you want someone who is really very good at his trade and runs a tight team I would recommend Mhilli Construction for your job.

Andy and his team did a fantastic job. Our neighbours were very uncooperative and restricted noisy working hours quite severely but Andy was very accomodating. He is very easy to talk to and happy to discuss ideas you may have concerning the build. I would definately reccommend him. We are delighted by the extension and will definately use Andy again in the future. Thanks!
