Advice
Why it’s worth doing now in Fratton
A tired-looking washroom doesn’t always need a refurbishment. Where tiles, panels and fittings are sound, new sealant may be enough to put it right for now. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.
What a job costs comes down to the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.

Fratton: questions and answers
Could you schedule work at a campus like University of Portsmouth for the vacation?
Yes. Education sites typically want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Is Fratton too far out for you?
Not at all. Fratton is within our area. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.
How do you deal with asbestos in old sealant?
The duty to manage asbestos sits with the building’s dutyholder, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.
Do you phase washroom resealing?
We phase it so there are always facilities open. One washroom, one bank of cubicles or one changing room is done at a time. Tell us your site hours and access windows and we’ll plan around them.
Do you do washroom sealing in healthcare settings?
Yes. Your infection-control rules, estates requirements and permits are followed, and phase the work so areas keep facilities.
Do you offer coloured sealant?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We’ll confirm the colours available for the specified product.
Will you come and look before quoting?
Photos, drawings or a schedule are often enough to quote. If the job needs a look first, we will arrange a visit.
What else we do in Fratton
Maintenance after handover
Regular inspection catches problems early. In particular:
- Keep washrooms out of use until we say the sealant has cured
- Note failing joints building by building
- Don’t leave an open joint at a basin or tray
- Mention any site permits or estates rules at quote stage
We hand each area back once the silicone has had the cure time the product needs. We will tell you when the wet areas can be used, and it helps if signs stay up until then.
Mould in a joint spreads along the bead and into nearby grout and users notice. Replacing it early keeps the job to a reseal.
Different surfaces, different methods
Basins and vanity tops
Basin joints get wet every time someone washes their hands, so the joint to the wall and around each bowl fails early. They are resealed with anti-mould sanitary silicone.
Showers and trays
A tray flexes every time it’s used and is constantly wet. Tray joints are where many washroom leaks start.
Commercial clients in Fratton
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Fratton. Several sites can go on one quote, so there’s one set of paperwork to deal with.
When it isn’t the sealant
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water from plumbing, not from a joint
- Vanity carcasses that have swollen
- Fittings that move too much to hold a bead
Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly before you book.

Sanitary sealant for Fratton buildings
