Commercial sealant in Charlton
Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. We work through rooms in batches, keeping most rooms available, with a cure time for each room so housekeeping know when to release it. We work on welfare facilities, retail & leisure sites and office washrooms & kitchens, and common reasons people get in touch are sealant failing again soon after quick repairs and washrooms that need sorting before an inspection.
Across London, offices, shops, hotels, student halls and blocks of flats all need sealant work from time to time, whether that’s washroom resealing or fire-rated sealant around service openings. Out-of-hours working can be arranged where a building in Charlton cannot close.
Big or small, it’s backed by our one-year guarantee.

When something else is needed
A few problems are outside what sealant work can do:
- A shower tray, bath or basin that is cracked or broken
- Certifying fire stopping or building compliance

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work starts. Most jobs take a few hours per area, with larger sites planned over several visits. In a London area like Charlton, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by looking at the rooms and agreeing what’s needed.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.
How to prepare
- Move anything stored near the joints
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Charlton questions
Can you help a landlord with a rental near Charlton station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Can parking be tricky for a visit in Charlton?
In much of London, parking needs planning: a visitor permit or a bay close to the door helps a lot, so mention what’s available when you book.
How much does commercial sealant cost in Charlton?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Which products do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Can you match the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Does someone need to be in?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
Do you work in Charlton?
Yes, we do. Our applicators work in Charlton.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Do you need commercial sealant in Charlton?
Plenty of commercial bathrooms have no window at all, and where extraction is poor, damp hangs around. Mould then takes hold in the silicone.
Common reasons people contact us include:
- Washroom sealant that looks dirty however often it’s cleaned
- Joints that need doing before an inspection or audit
- Large numbers of bathrooms needing the same work
- Split sealant around staff kitchen worktops and sinks
If you look after a building such as Thorntree Primary School, sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.
Questions to ask before you book
- Whether they’re fully insured
- Whether you can choose the colour
- What product goes in the joint
- How the surfaces are prepared before sealing
Looking after it afterwards
To keep the joints looking good and working properly:
- Include the silicone on your room checklists
- Plan resealing around quiet periods
- Log resealing so you know what’s due
- Check extract fans are actually running
A squeegee in each shower is a simple help: walls and trays dry faster, and so does the sealant.
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.
