I cannot recommend this company highly enough. Tudor & Darius did a brilliant job re-decorating my 2 bed flat, moving furniture around as needed without any fuss. They work quickly and meticulously neatly & cleanly. Tudor gave good advice on what type of paint to use on my woodwork, I didn't want it to look too shiny so chose eggshell. Whilst here they also sanded and re-hung my front door to prevent it from sticking. I would definitely use them again.
We have been working at this trade for over 15 years. My company and works people hold a number of different NVQ qualifications such as electrical, engineering, railway engineer, civil engineering.

We hired Cani Building Services to replace the front stairs and pathway of our Victorian home with granite pavers in the spring of 2025. When evaluating the builders it was important to us that we found somebody who was professional, reliable, and detail-oriented. Durim offered a competitive quote and promptly started work. ?He completed our job to a high level of quality within a week’s time, and we are very pleased with the outcome. We would absolutely recommend his services to others!

Fired him for appalling work, no-shows and delays; see his other bad reviews. He's a middle man; does not do any work; got others to do it like a plumber, then a tiler the next day; slow work made worse when someone messed up or did not show up. Ali only shows to deliver materials or check work. Quick to reply when wanting the job. Slow/no response once job starts thinking you wont cancel. Materials I paid not returned; take every receipt and check you keep/use every item as he will even for wipes/tape

My name it’s Cris. I am a person with many qualities in handyman.What a handyman means? A handyman, also known as a handyperson or handyworker, is a person skilled at a wide range of repairs, typically around the home. These tasks include trade skills, repair work, maintenance work, are both interior and exterior, and are sometimes described as "side work", "odd jobs" or "fix-up tasks". For me a handyman means the person who helps the people who are in need or not having the necessary training for that thing and at the same time the one who later gives a smile to the people's face. For this, please contact me in any need you have

Initial service was great. But grass that was laid hasn’t last a year with a lot of patches and bits that have died. I watered and cut the grass regularly as I trusted but the grass just hasn’t lasted. Unfortunately, after several requests for help, Christian hasn’t been very responsive and showing no signs of helping.

James Butler also trades as CGS Landscapes. He paved my driveway with poor quality slabs in September 2024 blaming the manufacturer and not himself. More broken slabs has been replaced by him 3 times in 6 months. He has refused to respond to my calls. He texted back calling me. STUPID when I texted him to say I will report him to RatedPeople and the authorities. More slabs broke 2 days ago. Sent him the picture. He simply texted back: MOVED TO DEVON NO LONGER WORKING. Please don’t hire James Butler.

I'd highly recommend John. He managed our expectations well from the start - turned up on time to quote, delivered a quote the next day as promised, provided references when we asked for them (who backed up that he's a good builder), found a space in his schedule quickly to fit our job in, did it quickly, efficiently and leaving no mess afterwards. And charged us a reasonable amount for the work. Couldn't speak more highly of him, and will definitely ask him to quote on our extension when we progress with the planning.
