Your questions about commercial sealant in Wilmington
Do you cover smaller places like Wilmington?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Berwick (Sussex) station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Can I add another job to the visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you provide RAMS?
Tell us what your site asks contractors for. We will confirm what we can provide alongside the quote.
Can new sealant go over the old?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. It all has to come out first.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Wilmington.
Can you reseal every bathroom in a hotel?
Yes, we can. Larger jobs are planned as a room-by-room or floor-by-floor programme, keeping most of it in use.
Can you work around guests in a hotel?
Yes, in most cases. Each visit covers an agreed batch of rooms.
Commercial sealant for homes and businesses in Wilmington
Mouldy or split sealant in a commercial building causes more than a bad impression. It’s a cleaning problem, a leak risk and something guests and staff notice. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on rental portfolios, student & care accommodation and welfare facilities, and common reasons people get in touch are failed joints in office kitchens and tea points and tired sealant in let properties.
Work in a small place like Wilmington is planned ahead, journey included, so it can be fitted around guests, customers or events where possible.
We stand behind the work with a 12-month guarantee, so you’re not left on your own once the job is done.

How to look after the new joints
Looking after new joints is easy:
- Keep strong chemicals and scourers off the joints
- Add sealant to your planned maintenance checks
- Log resealing so you know what’s due
- Give housekeeping the cure time for every room
A squeegee in each shower is a simple help: less water sits on the joints between uses.
Signs to look for: black spots in the silicone, corners lifting, staining on the ceiling below or a musty smell. Any of these means the joints need attention.
Leave it or put it right?
Refitting a washroom is a big, disruptive project. If the fittings are in good order, new sealant is often all it needs. We’ll tell you if we find anything that needs another trade. Where a wall is exposed, as many are in small places like Wilmington, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, phone 0345 464 0079 or send us an email for an honest opinion and a quote.

For landlords and businesses

Letting agents and landlords in Wilmington can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Commercial buildings in Wilmington
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as St Mary and St Peter's Church, halls and community kitchens see heavy use, and their sealant shows it. If you look after a building such as Willingdon Community School, busy washrooms and kitchens can be resealed in phases so they stay open. If you let a flat or house near Berwick (Sussex) station, we can quote for one property or a whole portfolio of rentals.

How the job changes by surface
Welfare facilities
Before a health and safety visit or audit, tired sealant is easy to sort. Tell us your deadline and we’ll plan the work and cure time around it.
Office washrooms & kitchens
A row of basins on a vanity top has a long joint that collects water. It’s cut out, cleaned and resealed in one neat line.
The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes as long as the scope needs, from one welfare room to a full building. Somewhere as small as Wilmington, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Tell us the rooms, hours and site rules, and we will plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- We reseal with the right product for each joint.
- Each finished area is checked with you and given a cure time.
Before we arrive
- Mention if the joints have been sealed before
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in
