Commercial sealant for homes and businesses in Erith
Mouldy or split sealant in a commercial building causes more than a bad impression. Cleaners struggle with it, water gets through it and people notice it. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on retail & leisure sites, student & care accommodation and welfare facilities, and the jobs we see most are tired sealant ahead of a health and safety audit and shower leaks reaching the floor below.
Commercial work in London comes with its own logistics: loading restrictions, building rules and tight access. For a building in Erith, we agree timings and access before anything starts.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Why act early in Erith
A leaking shower in a hotel room or flat above can damage the ceiling below. That means a second room out of use and a repair to pay for. Resealing first is the smaller job. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

The process
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. Expect the work to take a morning for a small washroom, and a planned programme for bigger sites. In Erith, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- Tell us the rooms, hours and site rules, and we’ll plan the programme.
- Tell us what paperwork your site needs, and we confirm what we can supply before any work starts.
- 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.
How to prepare
- Tell us if parking is tricky
- Clear items away from the joints we’re working on
- Mention any sign-in or site rules at work premises

Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
For anyone letting property in or around Erith, several properties can be quoted together. Send us the addresses and the work at each, and photos by email help.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Encourage users to squeegee shower walls
- Schedule work around occupancy
- Keep strong chemicals and scourers off the joints
- Check extract fans are actually running
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix.
Rooms out of use cost a hotel or landlord money. Catching faults early means they can be put right in a short window, before they become leaks that take the room out of use.
What affects the cost of commercial sealant
Every job gets its own quote. This is what makes a difference:
- Any mould that needs treating
- Access and height
- The number and length of the joints
- Any working-time requirements on site
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.
What we need to know
When you contact us, it’s useful to know:

Common problems we fix in Erith
Larger buildings move, and stud walls move more than solid ones. Joints between different materials take the strain and eventually tear.
Look out for these signs:
- Sealant failing again soon after quick repairs
- Too many rooms to reseal without closing the building
- Split sealant around staff kitchen worktops and sinks
- Tired sealant ahead of a health and safety audit
For buildings such as Christ Church, any kitchen and washrooms need the same sealant care as any other building.

FAQs for Erith
Is parking a problem for a job in Erith?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
I let a flat near Erith station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just ring 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
How long do rooms need to be out of use?
Usually after around 24 hours. Each room is handed back with the cure time for the product used.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
What sealant 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.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Will there be a smell?
Possibly a little. Any smell clears as the sealant cures.
Can I do it myself?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What commercial sealant looks like in Erith
Commercial buildings in London often have strict access rules and limited loading, and out-of-hours working is possible to arrange. London has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
