Commercial sealant in Crockham Hill, done properly
We fit the work around your building. We can work room by room, floor by floor or in batches, and out-of-hours work or early starts can be arranged. Common call-outs are for washroom sealant that looks dirty however often it’s cleaned and large numbers of bathrooms needing the same work, across welfare facilities, rental portfolios and retail & leisure sites.
Somewhere as small as Crockham Hill, commercial jobs tend to be pubs, holiday lets, farm buildings or halls rather than offices. They all have washrooms, kitchens and service openings that need the right sealant.
All our work comes with a 12-month guarantee, wherever you are in Kent.

How to look after the new joints
So the new joints stay in good condition:
- Keep strong chemicals and scourers off the joints
- Don’t leave a failed joint until the next refurbishment
- Leave squeegees in busy showers
- Report broken fans quickly
Extract fans need to work. In internal bathrooms, a weak or broken fan lets moisture linger, and that’s what keeps mould away.
In a commercial building, a leak can quickly spread beyond one room: through floors, into ceilings and across into corridors. Dealing with the joint early stops that spread.
Questions from Crockham Hill
I let a flat near Edenbridge station. Can you help?
Yes. We work for landlords and letting agents as well as householders, and several properties can be quoted together. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you cover smaller places like Crockham Hill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you take on large, multi-room jobs?
Yes. We’ll walk the site, agree the scope and the order, and give you one clear quote.
Where are you based?
Mr Mastic is based in Crawley. Our applicators cover Crockham Hill, along with the rest of our area.
How much does commercial sealant cost in Crockham Hill?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.
What should I tell you?
A short description and the location. If we need more, we will ask.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Is there any odour?
There can be a smell while the sealant cures, but it fades. Ventilation helps.
For landlords and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Do you need commercial sealant in Crockham Hill?
In an accessible wet room, water spreads across the floor every use, so the joints at floor level are under water often. A failed joint there can soon let water into the floor or walls.
Common reasons people contact us include:
- Joints that need doing before an inspection or audit
- Leaks from showers into rooms or ceilings below
- Failed joints in office kitchens and tea points
- Silicone laid over old silicone by a previous contractor
For buildings such as Holy Trinity Church, halls and community kitchens see heavy use, and their sealant shows it.
What your quote should include
- What insurance they hold
- The length of the guarantee
- Whether they seal over old material or remove it
- What the cure time is
Honest limits
A few problems are outside what sealant work can do:
- Failed tanking or loose tiles behind the sealant
- Extraction that is not working, which needs an electrician or ventilation contractor
- A shower tray, bath or basin that’s cracked or broken
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a single washroom, longer for a whole building. Somewhere as small as Crockham Hill, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- The first visit is a look round the site to agree the scope.
- Working hours are agreed, including early starts or out-of-hours work where it can be arranged.
- Each area is protected and stripped of old sealant.
- Once dry, every joint is resealed and tooled.
- Housekeeping or site staff are told when each area can be used.

Leave it or put it right?
Sealant work is quick by the room: it takes a few hours per area, with larger sites planned over several visits. After that, each area needs its cure time before use, so planning the order matters more than the hours on site. In a small place like Crockham Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.
