About our commercial sealant in Longworth
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. Our applicators renew sealant across washrooms, welfare areas, kitchens and guest bathrooms. We work on hotel bathrooms, student & care accommodation and welfare facilities, and people most often call us about failed joints in office kitchens and tea points and black, stained silicone in guest bathrooms.
For a small place like Longworth, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we are fully insured.
Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Log resealing so you know what’s due
- Pass on the cure time to whoever cleans the rooms
- Plan resealing around quiet periods
- Check extract fans are actually running
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.
A room that cannot be let or used is lost income. Small sealant faults caught early can be fixed between bookings or tenancies, instead of turning into a leak that closes the room.
How it works
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. Surfaces next to the work are protected before any work begins. The work normally takes as long as the scope needs, from one welfare room to a full building. In a small place like Longworth, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- In each room, the old bead comes out and the joint is cleaned and treated.
- We reseal with the right product for each joint.
- Rooms are handed back in order, each with its cure time.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

What sealant work cannot fix
Before you book, it’s worth knowing the limits:
- Poor ventilation that keeps bringing mould back
- Water coming from plumbing rather than sealant
- Cracked trays or baths rather than failed joints
Not sure which it is? You can phone 0345 464 0079 or send us an email and we will tell you honestly before you book.

What happens if it’s left?
Patching the worst rooms as complaints come in is hard to manage. A planned programme works through every room, with less disruption and one clear quote. Around Longworth, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

Common questions in Longworth
Do you cover Longworth for commercial sealant?
Yes. We work across London and the South East, and Longworth is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Is commercial sealant in Longworth guaranteed?
All our work, in Longworth and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
How soon can a room be used after resealing?
It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.
Can the hotel stay open while you work?
Yes. We agree the room order and times with your managers, and each room is handed back with a cure time.
Do I need to be at home?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you take on a whole building?
Yes. Our team has more than 20 years’ experience, and large programmes are planned around how the building is used.
What affects the quote in Longworth
You will get a clear quote before we start. It’s based on:
- When we can work, for business premises
- How many areas need sealing
- Whether the work is at height
- The amount of work
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
To make quoting easier, let us know:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- The problem you’ve noticed
- The rough size of the job
Call for a quick quote, or email us if that is easier. Describe what needs sealing and we will explain what’s involved before giving you a price.
What commercial sealant looks like in Longworth
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Managing a site like Longworth Primary School? Then sealant in washrooms, kitchens and changing areas can be renewed around term times or opening hours.

When to call us in Longworth

- Failed joints in office kitchens and tea points
- Washroom sealant that looks dirty however often it’s cleaned
- Failed floor-level joints in accessible wet rooms
- Mouldy bathrooms flagged at a tenancy check
