Commercial sealant in Brunswick Park
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 worktop sealant that has shrunk and stained and water marks on ceilings under bathrooms, we can put it right, whatever the surface.
London blocks of flats carry pipes and cables through walls and floors in their common parts and service risers. For managing agents and building owners in Brunswick Park, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or send us an email.

What commercial sealant looks like in Brunswick Park
Many London buildings have tight access and loading restrictions, and out-of-hours working is possible to arrange. London has hard water, which leaves limescale on sealant, grout and taps.
If you look after a building such as St Andrew the Apostle Greek Orthodox School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours. If you look after a church, hall or community building such as Oakleigh Community Church, any kitchen and washrooms need the same sealant care as any other building.

Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why it’s worth doing now in Brunswick Park
Before an inspection, audit or busy season, sealant is easy to overlook. Booking it in good time leaves room for the cure time before the visit, without a last-minute rush. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

What information do you need?

Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in.
Do the sealants smell?
Some sealants have a smell while they cure, but it fades. Opening a window helps.
Is the work guaranteed?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we’ll sort it.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Log resealing so you know what’s due
- Use mild cleaners on sealant, not bleach or abrasives
- Give housekeeping the cure time for every room
- Check the joints during routine room inspections
Include sealant in routine room inspections. 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. Dealing with the joint early stops that spread.
When to call us in Brunswick Park
A rushed reseal between guests rarely lasts. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
These are the problems we are asked about most:
- Large numbers of bathrooms needing the same work
- Split sealant where wet room floors meet walls
- Sealant failing again soon after quick repairs
- Water marks on ceilings under bathrooms
Rented homes near New Southgate station change hands often, and we can quote for one property or a whole portfolio of rentals.
What your quote should include
- Which sealant they’ll use, and why
- What insurance they hold
- Which colour the sealant will be
- What guarantee comes with the work
The process
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to several days, depending on the number of rooms in most cases. In Brunswick Park, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Joints are dried, then resealed and tooled neatly.
- Housekeeping or site staff are told when each area can be used.
Preparing for the visit
- Let us know about stairs, lifts or work at height
