Commercial sealant in Winchelsea
In a hotel, office or washroom, failed sealant is more than an eyesore. It’s a cleaning problem, a leak risk and something guests and staff notice. We reseal bathrooms, washrooms, welfare areas and kitchens so they look cared for again. If you’re dealing with sealant failing again soon after quick repairs and joints that need doing before an inspection or audit, we can put it right, on rental portfolios, retail & leisure sites and student & care accommodation alike.
If you have holiday lets, a converted barn used for business or a community building near Winchelsea, the washrooms, kitchens and any fire-rated joints need the same care as a big site.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The job generally takes anything from a few hours to several days, depending on the number of rooms. In a small place like Winchelsea, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Plan for the work area to be out of bounds to pets and children
- Tell us if parking is tricky

We won’t take on work that won’t last, so these are the limits:
- Failed tanking or loose tiles behind the sealant
- Fire risk assessments or certification
- Water coming from plumbing rather than sealant
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.

Why deal with it now?
A quick bead over the old sealant might get a room back in use today, but it will not bond, and it lifts again soon. One proper reseal beats several quick ones. In a small place like Winchelsea, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What it costs depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before we start, so you know where you stand.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Leave squeegees in busy showers
- Add sealant to your planned maintenance checks
- Keep extractor fans working and serviced
- Log resealing so you know what’s due
Include sealant in routine room inspections. Checking joints alongside other room checks catches failures before they leak.
Watch for the warning signs: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
Commercial buildings in Winchelsea
For seaside hotels, guest houses and holiday lets around Winchelsea, busy months put washrooms and kitchens under pressure, so it’s worth checking the sealant before the busiest weeks. Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
For site and facilities teams at buildings such as St Thomas' Church of England Aided Primary School, washroom and kitchen sealant can be programmed around term times or opening hours. Letting a property close to Winchelsea station? Then several rental properties can be resealed on one programme. For buildings such as The Parish Church of St Thomas the Martyr, its kitchen and washroom sealant needs looking after like anywhere else.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What affects the quote in Winchelsea
We quote each job individually. This is what makes a difference:
- The product the joint needs
- The old material and how stubborn it is
- Mould in or behind the old joints
- Whether the work is at height
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
