Commercial buildings in Richmond upon Thames
Richmond upon Thames has hotels and guest accommodation in and around it. Hotel work can be planned room by room, with out-of-hours working where needed. London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in.
Rented homes near Richmond station change hands often, and several rental properties can be resealed on one programme. If you look after a church, hall or community building such as Holy Trinity Richmond, any kitchen and washrooms need the same sealant care as any other building.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

What else we do in Richmond upon Thames
Common problems we fix in Richmond upon Thames
Commercial bathrooms get far more use than domestic ones, and they’re cleaned with strong products every day. So the silicone ages faster than it would at home.
The problems people generally mention when they call include:
- Tired sealant ahead of a health and safety audit
- Split sealant around staff kitchen worktops and sinks
- Failed floor-level joints in accessible wet rooms
- Washroom sealant that looks dirty however often it’s cleaned
Managing a site like Marshgate Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

Different surfaces, different methods
Student & care accommodation
Care homes need careful planning around residents, with each bathroom handed back with its cure time.
Office washrooms & kitchens
In staff kitchens, we degrease joints before resealing, with a food-safe product beside sinks where needed.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Schedule work around occupancy
- Leave squeegees in busy showers
- Log resealing so you know what’s due
- Add sealant to your planned maintenance checks
Add sealant checks to your planned maintenance. Checking joints alongside other room checks catches failures before they leak.
In a commercial building, a leak can quickly spread beyond one room: into ceilings below, walls next door and service voids. Early resealing keeps it from getting that far.
