Washroom sealing for businesses in Dorchester
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
After the work
Keep the joints in good shape with a few simple steps:
- Avoid scourers and harsh descalers on silicone
- Mention any site permits or estates rules at quote stage
- Include joints in routine washroom inspections
- Don’t leave an open joint at a basin or tray
Any failure in our workmanship within the 12-month guarantee is ours to put right. After that, a routine look catches failing joints early.
Inspectors look at whether kitchen surfaces can be kept clean. Resealing sinks, worktops and splashbacks before an inspection is a simple step.
How we handle washroom sealing in Dorchester
Accessible WCs, showers and changing areas have their own pinch points: wet-floor edges, tray perimeters, basin tops and the line where flooring meets the wall. An open joint there lets water track under flooring or behind wall panels so they get particular attention. If you’re dealing with shower tray joints that have opened up and failed sealant in a tea point or staff kitchen, we can put it right. Searching for sealant specialists in Dorchester?

Should maintenance staff do it?
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

How the job changes by surface
Showers and trays
Shower trays move under foot and are wet all day. Tray perimeters are a frequent source of leaks.
Wet-room floors and floor-to-wall joints
Wet floors are common in accessible showers and changing rooms so the edges are checked carefully.

Your questions answered
Can you take on a job at a hospital such as Littlemore Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do hotels near Dorchester have to close for sealant work?
Almost never. The work is phased so most rooms stay available. Tell us your quiet periods and access windows and we’ll plan around them.
What happens if old sealant might contain asbestos?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. Work pauses if suspect material is found, until it has been tested.
Do you take on small jobs?
Whatever the size, the process is the same: send details, get a fixed quote, we seal, guaranteed.
How long does a job like this take?
We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.
How do I request a quote?
The quote form is the simplest route, though you can also call 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.
How soon can a washroom be used after resealing?
The silicone needs time to cure before water reaches it. Phasing is planned with the cure time in mind so there are always rooms open.
