Craig got in touch quickly, gave me a rough estimate over the phone and answered all my questions. Surveyor arrived on time, gave instant quote. Price was good. Michael and (another) Craig turned up to do the job on the day, time given. Good, tidy job. Can't fault anything, from start to finish!! Would recommend!

George and his team are experienced builders, replaced my front door with a custom frame/sidelights and raising the floor level in the hallway quite quickly - in fact, they were the only who came next day, gave a quote straightaway and were ready to start in just couple of days. They also had all the necessary tools and materials, were ready to buy something additional quickly on the day - if further adjustments were required to fit everything as I asked. Thanks a lot for your help, guys!

Highly recommend. These guys did a fantastic job of constructing our pergola and decking. Very hardworking and reliable. The job was completed in the time frame agreed and to a very high standard. We would 100% use them again.

We engaged Stuart and his team in 2023 to help remodel our garage into a suitable office space and gym. In all, it has cost us an additional £4.5k to rectify the issues Stuart and his team made from a poorly fitted garage door which voided the manufacturer's warranty, poorly rendered exterior, numerous snagging issues and unfinished work. I would not recommend.

Hired paul to reconfigure my kitchen. He did not complete the job and walked out after 3 weeks leaving numerous jobs unfinished. Many things they did have had to be redone, the finish was shoddy and I don't think he knows what a right angle is. Would obviously not recommend, other tradesmen that have seen his workmanship have told me to report him to trading standards. He left me with a half finished job, saying he was not able to achieve the level of finish I was looking for.

Jason and his partner fitter a new bathroom for me, including all new plasterboard etc as water had gotten behind the old tiles. They tiled the floor and walls for us also. The bathroom looks brilliant couldn’t be happier, more than happy to trust them when not at the property and to top it all off when they were finished I went out to my garage so that I could take all of the rubbish to the tip and they had beat me to it. Will be hiring again for my second bathroom shortly!

AVOID AT ALL COSTS I can't recommend Tom. Previously TH&Jones Ltd he has changed the company name. He has left us with an extension that doesn't meet building regulations and needs to be taken down. Our house unsalable. I have an independent report to support it. Insufficient foundation, no damp course, insufficient insulation, incorrect installation of roof. He said he would rectify if we paid for 'things unquoted' but failed to show exactly what. We haven't heard from him in months. Stay away!!

Hired this tradesperson all went well for a short time - his team walked out on him and he could not get the appropriate trades to complete various stages of the build - after complaining about the constant delays he stated he would not come back and is now in breech of his contract- due to his inability to obtain the relevant tradespeople his plumbing “expertise” has now caused a leak underneath our newly fitted kitchen floor! Which we are having to pay to repair! Disgraceful!
