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!

Dmitry

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.

I would definitely recommend! Really hard working, genuine people with a very fair quote. Brilliant communication throughout. Couldn't fault anything they did and the finished room is brilliant. I will be using them again without a doubt and recommending them to anyone having work done. Even the neighbours commented about how dedicated and committed they were. 10/10 from us!

So glad I chose Plaster Master for my garage conversion. I could not fault their work. Tom informed me of each stage of the work. I was asked to check each phase to ensure it was to my liking and I was. If you are thinking of having work done use this company as they are absolutely fantastic. I will use them again without blinking an eye.

They also did little extra touches to make it just right. Thanks guys. Really appreciate it. I would highly recommend them.

Alex has completely refurbished my bathroom and i am thrilled with the result. Alex is very skilled and his work is excellent. He takes pride in what he does, and his attention to, and the care he takes with the smallest details, are not seen so often these days. Alex is obliging and helpfull with advice, and will consult his customer on details. He gets on with the job and does not mind staying late until he's finished what he is doing and cleans up before he leaves. He is a very pleasant man.

We are very happy we went with 1Horizon. We wanted to do some of the internal work ourselves and they were the only ones we spoke to who agreed to this. They were happy to work with us on our quote to get what we needed. Aiden and his team were friendly, honest and reliable throughout and the standard of work provided by all trades was excellent. I would have no hesitation in recommending to others.

Placed advert Thursday. Contacted same day by Mike with a view to coming out and quoting next day. Came on time priced the job on Friday and arranged to start work on the Tuesday. Mike worked with his son Silas. What a really nice pair. Genuine, polite and got on with the job even though I asked for a few tweaks along the way. Both very old school and worked at their own pace - happy with work carried out and will use them again. Reasonable price too.

This was just a quote for a loft conversion which was already there, I needed to know if it was up to current day regulations. this tradesman went out on the same day and was very efficient. He e-mail me the next morning with a run down of the repairs and costings. I would definitely rate him.

I was very satisfied with the results of VFurb's external renovation and decoration work, which took 3 weeks in total, extended due to rain. Dragos worked six days a week to keep me informed of progress, answered all my questions, and identified practical solutions to unforeseen problems, supported by detailed costings . He was always present to supervise his team of 2-4 workers, and personally completed the most complex roofing, piping and guttering jobs himself to a high standard.
