Commercial sealant in Upstreet, done properly
Hotel bathrooms take hard daily use and constant cleaning, so sealant there has a hard life. Rooms are resealed in batches, keeping most rooms available, with a cure time for each room so housekeeping know when to release it. If you have black, stained silicone in guest bathrooms and water marks on ceilings under bathrooms, we can put it right.
In a village or hamlet like Upstreet, commercial work is more likely to be a pub, a farm shop, holiday lets or a village hall than an office block. They all have washrooms, kitchens and service openings that need the right sealant.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

What affects the cost of commercial sealant
For a quick quote, just ask. What matters most is:
- How much old sealant there is and how hard it is to remove
- The number of rooms or windows
- Access and height
- Which sealant suits the joint
Combining jobs into one visit normally makes better use of the time than several visits. You’ll get one clear quote for the whole job.
What we need to know
You don’t need to know the technical terms. It helps if you can tell us:
- Any access issues, like height or stairs
- Where the job is, and your postcode
- Pictures of the joints, sent by email
- If it’s domestic, commercial or a hotel
Getting a quote is simple: tell us what needs doing and where. A few pictures by email make the job easier to understand, and we’ll come back to you with a quote.
Why deal with it now?
In a building with rooms above rooms, a failed shower seal can soon show on a ceiling below. That means a second room out of use and a repair to pay for. A reseal now avoids that. Around Upstreet, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

How long do rooms need to be out of use?
Generally after around 24 hours. Each room is handed back with the cure time for the product used.
Do you offer different sealant colours?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before we start.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Is commercial work guaranteed?
Yes, with our 12-month guarantee. Regular gentle cleaning and working extraction help the sealant last.
What does commercial sealant cost?
Size, access and the old material all affect the cost. Ask us for a quote and we will talk you through it.
Can the hotel stay open while you work?
Yes. Rooms are done a few at a time, so only a few are out of use at once. Each room comes back with its cure time for housekeeping.

From a single let to a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
What commercial sealant looks like in Upstreet
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
If you look after a church, hall or community building such as Church of St Mary the Virgin, its kitchen and washroom sealant needs looking after like anywhere else. For site and facilities teams at buildings such as Chislet Church of England Primary School, busy washrooms and kitchens can be resealed in phases so they stay open.

Advice
When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Poor ventilation that keeps bringing mould back
- Cracked trays or baths rather than failed joints
- Leaking pipework, valves or wastes (a plumber’s job)
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.
Surfaces we seal
- Office washrooms & kitchens
- Student & care accommodation
- Welfare facilities
- Hotel bathrooms
- Rental portfolios
- Retail & leisure sites
When to call us in Upstreet
In office kitchens and tea points, joints are wet and wiped all day, and grease and cleaning sprays break down sealant. Worktop and sink joints are often the first to go.
People usually contact us when they notice one of these:
- Water marks on ceilings under bathrooms
- Sealant failing again soon after quick repairs
- Too many rooms to reseal without closing the building
- Joints that need doing before an inspection or audit
For landlords with property near Sturry station, several rental properties can be resealed on one programme.
