Very few tradesmen can engage in a detailed, professional and friendly manner. They took out an old kitchen and replaced it with a new one - which the helped source at below market cost saving us in excess of £5000. Right from conception to finish, there was full transparency of the costs and crucially at the end, no cost overruns. Definitely five stars and will reengage again for other building/renovation works I have planned.

Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.

Extensions- 3 Oct 2022
I gave him the opportunity as I was desperate to find someone fast,and didn’t have much success on here.Soon as he accepted,he was already asking for cash beforehand to get materials.I thought you know what,his company details are online,what can go wrong so I did.As his team started the job, they told me I needed to have 2 fences erected as they were badly damaged and deteriorating.I thought heck,why not,might aswell do it now so I gave him again, the opportunity to make some extra business with us.Again,was asked for some pre payment to get the materials,all in cash.All was finished within 2days of the weekend.Fence looked fine,but the roof just looked like a cowboy job.I didn’t complain,as it was done fast,with all the stress with opening a new business,it was one less headache out of the way.After 1 day of rain,the roof was already leaking,like absolutely everywhere.Called him, and he got someone to come by a few days after to fill in more silicone.(Very suspect job again).I thought fine, aslong he’s responding and trying to fix the situation.Fast forward few days later, bearing in mind the shop isn’t open and I’m not always there when it’s raining,it rained again and it was leaking in some areas again.Whatsapped him which is how we normally communicated,called him,read my messages but no reply. Now he has blocked me.Seriously, how he knows I’m opening a business soon this is how he wants to treat his customers. Simply give me back my money or fix the problem, simple!

Job was to convert existing garage into a home office and retain storage space too. Very impressed from start to finish, and would thoroughly recommend (already have to family and friends!). Communication was great, helped to talk through our initial idea and made some recommendations which we took up and made it even better. Flexible to work around our commitments at home, and all elements of the job delivered to a high standard. Would certainly use again when we have another project to do. Thanks.
