How we handle commercial sealant in Allen's Green
In a hotel, office or washroom, failed sealant is more than an eyesore. 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 office washrooms & kitchens, retail & leisure sites and hotel bathrooms, and the jobs we see most are too many rooms to reseal without closing the building and washroom sealant that looks dirty however often it’s cleaned.
For a small place like Allen's Green, the journey and timings are agreed in advance, so it can be fitted around guests, clients or events where possible.
Whatever the size of the job, it’s backed by our 12-month guarantee in Allen's Green and across Hertfordshire.

Keeping the joints in good condition
So the new joints stay in good condition:
- Act on lifting sealant before it leaks
- Ask cleaners to go gently on the silicone
- Encourage users to squeegee shower walls
- Keep extractor fans working and serviced
Make it easy for staff to flag a failing joint. A small gap caught quickly is a short fix, and if anything looks wrong, just ring 0345 464 0079 or send us an email.
Planned resealing is easier to manage than emergency repairs. We can fit the work around bookings, shifts and opening hours, instead of rooms closing without warning.

Your questions about commercial sealant in Allen's Green
Can you help a landlord with a rental near Sawbridgeworth station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Allen's Green within the area you cover?
Yes, Allen's Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you guarantee commercial jobs?
Yes. Our 12-month guarantee covers commercial work too.
How long does the job take?
It depends on the size of the job, but most jobs take a few hours for a single washroom, longer for a whole building. We will give you a better idea when we quote.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can you take on a whole building?
Yes. Larger jobs are planned as a room-by-room or floor-by-floor programme, so only part of the building is affected at once.
Will you leave a mess?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Is out-of-hours working possible?
Often, yes. Let us know when the building is quietest, and we’ll plan the work around them.
What sealant work can’t fix
To be straight with you, there are a few things sealant will not fix:
- Faulty shower valves and leaking traps
- Poor ventilation that keeps bringing mould back
- Damaged sanitaryware that needs replacing
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Quotes for commercial sealant in Allen's Green
There’s no set price list. The quote depends on:
- The size of the job
- The old material and how stubborn it is
- The type of sealant required
- Working hours on commercial sites
No two jobs are quite the same, so we quote each one individually. 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.
Asking for a quote
Photos by email are helpful but not essential. Please mention:
- How we’d reach the joints
- The rough size of the job
- What’s wrong with the joints now
- Whether it’s a home or a business
Call for a quick quote, or email us if that’s easier. Tell us about the joints that need doing and we will talk you through the work and give you a clear quote.
Different surfaces, different methods
Student & care accommodation
In care settings, we agree the order and timings with staff, and staff are told when each bathroom can be used.
Office washrooms & kitchens
Office washrooms and tea points are used all day, so the work can be arranged for quieter times. We reseal around basins, urinals, worktops and sinks.
Leave it or put it right?
Guests and staff judge a building by its bathrooms. Black sealant makes a clean room look dirty, and scrubbing will not fix it. New sealant does. In a small place like Allen's Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
