Sealant specialists in Cooling
Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. We work on external facade joints, floor and threshold joints and kitchen worktops and splashbacks, and the failures we’re asked to look at most are messy, uneven beads from earlier work that let the building down and a top-up bead over failed sealant, now lifting. Looking for mastic applicators who cover Cooling? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.
The most common commercial job in Cooling is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
A job in a smaller place like Cooling is typically a single building. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Common questions from Cooling clients
Can you supply sealant in our brand colour for a site in Cooling?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.
Can being near the sea in Cooling affect the sealant we need?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
When is resealing likely to be due?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.
Can you supply RAMS and insurance details?
We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Every applicator holds a CSCS card.
Do you work in Cooling?
Yes. Sites across Cooling are covered, with one number for every area we cover.
Our process
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. Smaller jobs around Cooling can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We start with the evidence: photos, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- We agree the order of work, access windows and site hours with you.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Preparing the site
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- For older buildings, check the asbestos register before work
Quotes
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Cost factors for sealant joints
Sealant work doesn’t have a standard rate, since sites vary so much. What we look at:
- Access and working height
- Whether old sealant has to be cut out first
- Joint width, depth and condition
- Site requirements such as inductions and permits
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.
Sending details for a quote
Diagnosis starts before we arrive. Let us know:
- Access details, including height
- The type of building and who uses it
- A wide shot and a close-up of the area
- The postcode of the building
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:
- Keep a record of which joints were resealed and when
- Make sure contractors see the asbestos survey before cutting out old mastic
- Brief cleaning contractors to avoid scourers and blades on sealant
- Don’t let cleaning or traffic back on before the cure time is up
Give fresh sealant time to cure before it’s cleaned, wetted or walked past. That time depends on the product, the temperature and the joint depth. Keeping signs or barriers up until then protects the finish.
Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.
Common problems we fix in Cooling
No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. In commercial buildings those factors tend to act together.
Typical triggers for a call:
- Shrunken sealant along kitchen worktops and splashbacks
- Leaks that seem to come through a sealant line
- Earlier reseals applied straight onto the failed bead
- External beads that have gone brittle and cracked
Shops and cafés around stations like Higham station, 3.3 miles to the south-west of Cooling, trade from early, so work is timed around them.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- Proof of insurance

What Cooling’s businesses ask us to seal
With the shore within about 3 miles, Cooling counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. A matched colour is only half the brief on an exposed frontage. The South East is one of the drier parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
Whatever the building in Cooling, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

Leave it or put it right?
Spot repairs have their place. If the rest of the bead is the same age and product, though, it’s typically close behind. We can price both options so you can decide on the facts. Around Cooling, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.

When something else is needed
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- A dripping trap, valve or pipe behind a fitting
- Walls or slabs moving more than any sealant can take
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer.
