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!!

Groundwork & Foundations- 22 May 2026
John did a fantastic job with the groundworks for our new 150sqm block driveway. He priced keenly, started quickly and was on-site consistently every day for the week. Really skilled with the digger, good at dealing with the neighbours and always fun to talk to. Some aspects of the job changed based on what the dig uncovered, but he was pragmatic and ultimately left me feeling that he just really wanted to do a good job as if it was his own. Highly recommended - 10/10.

What to ask a Windlesham extension builder before hiring?

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

An extension builder in Windlesham 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.

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Windlesham?

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 Windlesham extension builder’s ability to deliver a result that meets your expectations.

Do you offer a guarantee for your work? Most Windlesham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
