About our commercial sealant contractors in Coombe
Inside a commercial building, sealant does a lot of quiet work: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, picking the product for each location rather than one tube for everything. If you have sanitary sealant that has gone black and patchy and water staining near frames, panels or ceilings, we can put it right, whatever the surface. For commercial sealant work in Coombe, you deal with one contact from quote to sign-off, whether it’s one building or several.
A lot of what we do in Coombe is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
A job in a smaller place like Coombe is typically a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When it isn’t the sealant
Honesty saves time and money. Fresh joints won’t solve:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Walls or slabs moving more than any sealant can take
If you are not sure, just give us a call on 01277 525 020 or email a schedule or drawings and we will give you a straight answer before you book.
Joints and surfaces we work on
- Floor and threshold joints
- Movement joints in walls and floors
- External facade joints
- Washrooms and tea points
- Kitchen worktops and splashbacks
- Window and door perimeters
When to call us in Coombe
External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.
Clients usually get in touch after noticing one or more of the following:
- Water staining near frames, panels or ceilings
- Expansion joints with the sealant torn out
- Smeared sealant across finishes from a rushed job
- Window and door perimeter joints that have cracked open
Offices and shops close to stations such as Sandwich station, 2.1 miles east of Coombe, tend to be busy all day, so sealant work is planned around opening hours.
Before you book anyone
- Whether old or failed sealant will be cut out, not overlaid
- How long is the guarantee, and what does it include?
- Will RAMS and insurance details be available?
- Are they CHAS accredited or on Constructionline?
Should maintenance staff do it?
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Keeping the joints sound
After handover, these steps help:
- Ask fit-out and M&E contractors to report any sealant they disturb
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Don’t let cleaning or traffic back on before the cure time is up
- Check the asbestos register before anyone disturbs old sealant in an older building
Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces.
Sealant installed at the same time normally fails in sequence. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.
Why act early in Coombe
Putting off a reseal typically moves the cost rather than avoiding it. Once water gets behind the seal, finishes and ceilings underneath are next. Dealing with it while the damage stops at the bead is the cheaper route. Converted and older buildings near places like Coombe tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- Failed material removed, not covered up

Working on commercial sites near Coombe
Coombe lies roughly 62 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings. Rainfall across the South East, Coombe included, is lower than in many parts of the UK. That helps, but frost and condensation on glass and coated frames still stop outside sealing on some winter mornings.
Parks like Birnham Farm Business Centre (0.8 miles south of Coombe) see tenants come and go, and every move-in brings joints to seal. In hotels such as The Lion Hotel, which lies north-west of Coombe, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes.
Coombe is about 6 miles north-west of Deal, in Kent. We cover Coombe and the rest of Kent, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. 931 places across Kent fall within our area, including Coombe. There’s a separate page for London, about 62 miles away.

How a job runs
Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before we move to the next.

- First, details reach us through the quote form or a site visit.
- The cause is diagnosed and the scope priced as a fixed quote.
- Work is phased around your occupiers where areas need to stay in use.
- Old sealant is cut out completely, never sealed over.

- A final walk-round, then the 12-month guarantee applies.

FAQs: Coombe
Is Coombe off your patch?
No. Places such as Coombe are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can the sealant on our Coombe premises match the finishes?
Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Send colour references or photographs and we will confirm what’s available for the product.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Can you supply RAMS and insurance details?
Send your site requirements with the enquiry. For older buildings we’ll ask for the asbestos register, plus your site induction rules.
Which sealant will you use?
If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Do you check for asbestos before removing sealant?
On older buildings, our first request is the asbestos survey. Managing asbestos is the dutyholder’s responsibility.
Do you hold CHAS accreditation?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
