Painting & Decorating- 24 Feb 2020
Quite literally the worst tradesman I have ever worked within 25 years as a property developer! He came and quoted to paint my house (a good price I must say), little did I know that this meant he would spray everything that he can see, not prepare the surfaces by sanding them down or protects things. This included door handles, hinges, radiators, alarms sensors, tiles and my own furniture and cooking utensils. First time I confronted him about this he said that we would clean everything, and we agreed to carry own. However, it became apparent that we was doing the same as previously discussed. have paid hi 66% of what was agreed, I quickly realised that the damaged he has caused was going to cost me far more and I told him to leave. The next day he turned up at my house with his wife demanding the balance which I refused to give him, they were both shouting outside my house, threatening to call the police. I eventually agreed to pay the 50% of what was left, just so that they would leave. However, even once he had confirmed writing his acceptance of this, he walks over to me and threatened me one final time, saying that he will take me to court etc, there is god and he will see to me! I advise to stay away from this person, better to pay a little more and work with professionals who don't agree with one thing and do another. He paints using a spray, which means you can not touch anything up and he quite literally paints everything he sees!!

UKPC Construction is by far the best company I have ever worked with, and I highly recommend them to anyone. Their team is not only courteous and professional but also a breeze to work with. They expertly helped me transform my jungle-like garden, and although I'm writing this review after some time, I'm now looking forward to discussing the extension project they initially designed with me. A big thank you to UKPCC, and I wholeheartedly endorse their services to everyone.

Bricklaying- 25 Feb 2021
My Mum is soo pleased with the completed job, Tommy has made good of a previous bad job by somebody that I hired off of this site. He was polite, quick to respond and due to the weather he wouldn’t start the job as it would’ve be in vain. We would thoroughly recommend him to the point my Mum has also booked him to do her front pathway.

Painting & Decorating- 6 Apr 2026
I had a very positive experience working with Konstantinos. He is personable, reliable, professional and excellent at co-operating throughout the process. He repainted my entire flat/walls/ceilings to a high standard (and sanded down) he also helped address a few additional repairs along the way. The finish is clean, fresh, and has completely transformed the space. He was thorough and ensured everything was completed properly and on time. I particularly appreciated his attention to detail and his proactive approach in taking care of things I hadn’t even noticed. I would happily recommend Konstantinos and would work with him again in the future! Thank you

What qualifications and experience do you have as an extension builder in East Grinstead?

An extension builder in East Grinstead should have a strong track record with similar projects and relevant building qualifications or trade memberships, such as the Federation of Master Builders (FMB) or TrustMark.

What experience do you have with similar extensions in East Grinstead?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the East Grinstead extension builder’s ability to deliver a result that meets your expectations.
