Bathroom Fitting- 8 Jan 2025
Venice construction did an excellent job installing a new shower cubicle in our bathroom, removing the bath and completely re tiling 3 walls. Veselin is extremely competent , pleasant and very hard working. I was astonished by his ability to restore the toilet every night so that we did not have to come downstairs. I am delighted with our new bathroom and the quality of the workmanship. Many, many thanks.

I’m so happy with the work that was done by Jon and the team at JMR. You’d never even know my garage was a garage before with the amazing work they did.

Thank you Jason! What a nice job! I would thoroughly recommend Jason to anybody. He is polite, professional, tidy, and very talented. I was looking for a tradesperson who offered exceptional attention to detail as things like doors and skirtings you have to look at forevermore, and i think i found him. Jason wasn't quite my cheapest quote (there wasn't much in it), but he came across well when i met him, and I'm glad i did go with him. I'll be asking Jason back to help with other jobs i have. Thanks!!

John from His & Hers construction did a very good job on our rear patio. It needed two sections of older, large porcelain tiles taking up and then new tiles putting down to match in with the rest of the patio.

Extensions- 28 Sep 2021
There were positives and negatives to the delivery of this job. More positives than negatives. The job took far longer than expected due to shortages and delays in obtaining materials, some bad weather and builders spending time on other jobs instead of concentrating on the ours. However, the job was generally done to a very reasonable standard and was more than satisfactory. My only concern was the site, especially indoors, was not left clean and tidy at the end of each day.

Extensions- 15 Apr 2021
So delighted with the finished room, Jay had some great ideas and could visualise how it would look, which exceeded my expectations. Jay and Rhys are both highly skilled and very good at what they do, in particular the plastering and finished render looks fantastic. These works have transformed the outside area for me and with the patio laid to a high specification too I can’t wait to start using the garden again. Jay added steps and a low level wall that I hadn’t considered for the path and patio and this was so great to see as I hadn’t anticipated these elements looking so good. Thank you Jay and Rhys, really pleased with how it all came together. (I have also asked for some further works to be done based on my experience so far)

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

An extension builder in Whitstable 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 Whitstable?

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