How we handle commercial sealant in Astwick
Landlords and agents with several properties can have bathrooms and kitchens resealed between tenancies. We can quote for several properties at once to keep things simple. We work on student & care accommodation, hotel bathrooms and rental portfolios, and the jobs we see most are sealant failing again soon after quick repairs and too many rooms to reseal without closing the building.
For a small place like Astwick, the journey and timings are agreed in advance, so the job can fit around bookings, guests or opening times where possible.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What happens if it’s left?
Sealant work is quick by the room: the job takes as long as the scope needs, from one welfare room to a full building. After that, each area needs its cure time before use, so the programme is planned around cure times. Older cottages and farmhouses around Astwick can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

How the visit works

All told, the work takes as long as the scope needs, from one welfare room to a full building.

- The first visit is a look round the site to agree the scope.
- We agree when we will work, with early or out-of-hours slots where they can be arranged.
- Areas are protected and the failed sealant removed.
- Once dry, every joint is resealed and tooled.
- We let your team know the cure time for every area.

Related advice
DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Commercial buildings in Astwick
Hard water is the norm across most of the South East, 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 St Mary's CofE Academy Stotfold? Then busy washrooms and kitchens can be resealed in phases so they stay open. Community buildings like Church of Saint Guthlac are part of the picture too: any kitchen and washrooms need the same sealant care as any other building.

What affects the cost of commercial sealant
We don’t publish a price list. The quote depends on:
- Any mould that needs treating
- The number and length of the joints
- When we can work, for business premises
- The product the joint needs
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What to tell us for a quote
What to tell us when you ask for a quote:
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
- Where the job is, and your postcode
- A few pictures by email, if you can
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Honest limits
New sealant can’t fix everything, and we will tell you before we start. It will not solve:
- Failed tanking or loose tiles behind the sealant
- A broken extractor fan behind the mould problem
- Cracked trays or baths rather than failed joints
If you are not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

How long do rooms need to be out of use?
It depends on the product, but around 24 hours is typical. Housekeeping get the cure time for each room.
Is it OK to seal over old sealant?
No. New silicone will not bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Do you offer different sealant colours?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
When to call us in Astwick
Quick fixes come back quickly. Sealing over old silicone, sealing wet joints or using the wrong product all lead to the same thing: another reseal before long.
People generally contact us when they notice one of these:
- Silicone laid over old silicone by a previous contractor
- Tired sealant ahead of a health and safety audit
- Split sealant around staff kitchen worktops and sinks
