Jason came quickly after speaking over the phone, after the leak got worse he got the scaffolding up quicker than we originally agreed. He didn't ask for a deposit and kept me updated throughout, cleaned up before he left. Would highly recommend.

Landscaping- 1 Dec 2020
Arron and his business partner Mark were extremely professional in their approach, their work was "spot on". Customer Service was important to them and was delivered to a high standard. They were flexible too and willingly did those little extras that always seem to crop up. We'd not come across them before so were delighted with the above. Of course we would recommend them.

Tony is possibly the best option you have. He is genuine, trustworthy, a man of his word and prices competitively. Even if he isn't the cheapest quote you get you should still try to employ him as he won't let you down. He's been doing this sort of thing since he was a young lad, and even though he's still relatively young in the scheme of things do not be fooled, he knows his stuff. It has been an absolute pleasure having Tony do our extension, and I am very happy to have anyone over who wants to take a look to discuss the quality of his work before proceeding with him. And no, this is not a plant! I am just a very happy customer.

What can I say. This man understands customers and all aspects of building work. Has completed two phases of work to a really high standard. This included fitting a new kitchen and bathroom, plastering and plenty of carpentry. Steve is clear on pricing and gives customers a plan. Any additional work and costing are agreed before he proceeds. Steve offers vision and ideas and helps you understand where you might be making a poor decision. Hes punctual and reliable. Overall has helped us transform our rundown bungalow into a modern family home. Cant praise or thank him enough.

Handyman- 14 Jul 2018
Would not recommend. Grouping poor & cracking, tiles not flush causing build up of grime. Cases not fixed properly. Chipped window sill. Flooring starting to move. Didn't want to leave feedback but 2 years on and we are having to have things replaced. Don't want to ask them back as getting them to replace our bath they broke was drama enough. A lot of money spent on this project we'd of never expected to have to touch it for years. Very disappointing
