What affects the quote in Crouch
There’s no set price list. The quote depends on:
- The product the joint needs
- Any working-time requirements on site
- The amount of work
- Whether old sealant or filler has to be cut out
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What we need to know
To help us quote quickly, let us know:
- What’s wrong with the joints now
- Photos by email, if that’s easy
- Roughly how big the job is
- Whether it’s a home or a business
Getting a quote is simple: let us know what needs doing and where. A few photos by email make the job easier to understand, and we’ll take it from there.
Fire rated sealant in Crouch, done properly
Until it’s heated, intumescent sealant behaves like an ordinary sealant; then it swells to help close the gap. The right product depends on the gap size, the substrate and what passes through. We work on service penetrations, door frames and flats & HMOs, and people most often call us about door frames with gaps between frame and wall and ordinary sealant used where a fire-rated product was needed.
For a small place like Crouch, the journey and timings are agreed in advance, so it can be fitted around guests, customers or events where possible.
The work is guaranteed for twelve months. If something isn’t right with it in that time, tell us and we will put it right.

What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, carry out the job and tidy away. It generally takes from a few hours to a few days, depending on the number of gaps and the access. In a small place like Crouch, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we work through your list or survey, measuring each gap and checking what it’s formed in.
- Anything that isn’t fit for the job comes out, and the gap is cleaned.
- Backing or fill is fitted where the product’s tested detail calls for it.
- Fire-rated or intumescent sealant is applied to the right depth and tooled.
- Locations and products are noted so you have them on file.
Before we arrive
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Store the list of sealed gaps with your building paperwork
- Take photos of fire stopping before ceilings or boxing go back
- Tell trades working in the building that fire seals must be put back
- Plan fire stopping into any work that goes through walls or floors
Do not drill through or remove a fire seal without putting it back properly. If you need new services through a sealed wall, plan the fire stopping as part of the job.
If a fire risk assessment has flagged a gap, do not leave it for the next one. Have it sealed, then keep the record so you can show it was dealt with.

Workplaces and buildings in Crouch
In England, the Regulatory Reform (Fire Safety) Order 2005 requires a fire risk assessment for workplaces and for the common parts of blocks of flats, and gaps around services are often picked up there. We work to the specification you’re given, installing the product to its tested details.
Community buildings like Church of St Mary are part of the picture too: older buildings that have had new heating or wiring often have service gaps worth checking. If you let a flat or house near Borough Green & Wrotham station, new cables or pipes through a fire-resisting wall leave a gap that needs the right sealant.

Different surfaces, different methods

Plasterboard walls
We check that the board around the gap is sound. Crumbling edges are cleaned back before the sealant goes in.
Do you need fire rated sealant in Crouch?
Over time, buildings change layout and use. Conversions to flats and HMOs, and office refits, create new walls and new routes for services, with gaps to match.
If you can see any of these, it’s time to have the joints looked at:
- Holes left by a change of layout
- Seals cut through by electricians, plumbers or data installers
- Open gaps behind door architraves
- Fire seals that have cracked with movement
For site and facilities teams at buildings such as Borough Green Primary School, fire-stopping around service openings should be restored whenever new services go in.

FAQs for Crouch
Can you help a landlord with a rental near Borough Green & Wrotham station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear price.
Do you cover smaller places like Crouch?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long will you be here?
As a guide, most jobs take anything from a few hours to several days, depending on how many gaps there are. Bigger jobs take longer, and we will tell you how long to expect.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Do I have to be there?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
What’s the difference between intumescent and fire-rated sealant?
Intumescent means it swells when heated. Intumescent sealants are one kind of fire-rated sealant; which product suits depends on the gap, the substrate and the service.
Where is Mr Mastic based?
We work from Crawley. We cover Crouch and the rest of Kent.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
When something else is needed
New sealant cannot fix everything, and we will tell you before any work starts. Sealant won’t put right:
- Construction that doesn’t provide fire resistance on its own
- Large holes that need a different fire-stopping system
- Doors that aren’t fire doors in the first place
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Surfaces we seal

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
