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
