I couldn’t be happier with the work done on our partition wall! From start to finish, he was reliable, professional, and clearly takes pride in what he does. He treated our home with respect, kept everything tidy, and communicated well throughout the process. The finished result is exactly what we asked for—neat, solid, and completed to a really high standard. It’s not always easy to find someone you can fully trust with work in your home, but he absolutely delivered. I genuinely cannot recommend him high

We were very impressed with Dan’s attention to detail, standard of workmanship and care taken. We were happy with the original installation but it is a tribute to Dan that he identified an issue and came back to do more work until he was satisfied it was just right. Dan kept us informed of progress and was very pleasant to deal with. When we had an issue with planning permission Dan provided detailed drawings of the sash window specifications. No hesitation in recommending. Windows look lovely.

I'm a mobile Locksmith based in Ashford, Middlesex. I work in the following postcodes TW and KT but that doesn't mean that if you're in London or surrounding area you are too far. I also do some handyman jobs in between or if I'm in a certain area or the customer requests it. I take pride in the work that I do, so a job will never be done just to be done, it's either working as it should or it doesn't. Best regards
