Commercial & hotel sealant in New Malden, Greater London
Professional commercial sealant in and around New Malden, with old sealant always removed completely and a 12-month guarantee.
- Too many rooms to reseal without closing the building
- Leaking joints in shower rooms and changing areas
- Water marks on ceilings under bathrooms
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Commercial sealant in New Malden, done properly
In showers and washrooms we use anti-fungal sanitary silicone, with a food-safe sealant by kitchen sinks where needed. We use sealants from Arbo and Everbuild, applied by ARBOMaster approved applicators. We work on student & care accommodation, rental portfolios and office washrooms & kitchens, and common reasons people get in touch are silicone laid over old silicone by a previous contractor and leaks from showers into rooms or ceilings below.
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 New Malden, that can mean fire-rated sealant around service openings as well as resealing in shared washrooms and kitchens.
Each job carries a 12-month guarantee, whatever its size.

What happens on the day
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job usually takes a few hours per room, so whole buildings are phased, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in New Malden. A visitor permit or a nearby bay makes the visit run more smoothly.
- The first visit is a look round the site to agree the scope.
- We agree when we’ll work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks

Quotes for commercial sealant in New Malden
You’ll get a clear quote before any work starts. It takes into account:
- The type of sealant required
- The old material and how stubborn it is
- Access and height
- Any mould that needs treating
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

When you contact us, these details help:
- The problem you’ve noticed
- The type of property

Work for landlords, hotels and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Leave it or put it right?
Refitting a washroom is a big, disruptive project. When the fittings are sound, renewing the sealant brings it back with far less upheaval. We’ll tell you if we find anything that needs another trade. In a flat in New Malden, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and send you a clear quote before work begins.

Common questions in New Malden
Can you help a landlord with a rental near New Malden station?
Yes. We work for landlords and agents as well as homeowners. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Do you cover New Malden for commercial sealant?
Yes. We work across London and the South East, and New Malden is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear quote.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can you match the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours for many products, and we will agree it with you first.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Are you an approved applicator?
Yes. We’re approved under the ARBOMaster scheme.
Do I have to be there?
That depends on where the joints are. Inside work needs someone to give us access.
Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Check the joints during routine room inspections
- Book larger programmes for quieter times of year
- Act on lifting sealant before it leaks
- Ask cleaners to go gently on the silicone
Ask staff to report splits or lifting sealant early. Catching one split early can save a leak later.
Mould in shared washrooms gets noticed and talked about. Left long enough, it spreads through the bead, and only replacement fixes it.
Do you need commercial sealant in New Malden?
Staff kitchens and food areas see constant splashing and wiping, and grease and cleaning sprays break down sealant. The worktop and sink edges usually fail first.
People generally contact us when they notice something like this:
- Washroom sealant that looks dirty however often it’s cleaned
- Shower leaks reaching the floor below
- Leaking joints in shower rooms and changing areas
- Rental bathrooms that need resealing between tenants
Schools such as Christ Church New Malden CofE Primary School are buildings too, and washroom and kitchen sealant can be programmed around term times or opening hours.
