Why choose Bristol Sealants?
Customers choose Bristol Sealants because we are reliable, flexible and take genuine pride in our work. We understand the importance of clean finishes, meeting deadlines and keeping projects running smoothly, whether it is a small domestic job or a large commercial project.
The business is run by Ashley Zampella and built on years of hands-on experience across the construction industry. That background means we know how the right preparation and the right product make the difference between a finish that lasts and one that fails.
We work to a tidy edge every time, colour match where possible, and remove and replace old or failed sealant properly rather than patching over it. We are fully insured for all work we carry out.
From a single bathroom to a full site package, we aim to deliver the same high standard every time: reliable, easy to deal with and finished to a professional standard across Bristol and the South West.

Do you colour match sealants?

Why should I replace old sealant?
Old or damaged sealant can lead to water damage, draughts, mould and an untidy finish. Replacing it helps protect surfaces and keeps everything looking clean and professional.
