Commercial sealant contractors across Blackheath
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t normally be cleaned out. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
Commercial kitchens and tea points
A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. We seal to a neat, cleanable finish and work around service times you agree with us.
Sealant applicators in Blackheath
Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Blackheath, the quickest start is to call 01277 525 020 or use the quote form with a list of addresses. If you’re dealing with mouldy silicone around WCs, urinals and vanity tops and external beads that have gone brittle and cracked, we can put it right, on kitchen worktops and splashbacks, external facade joints and window and door perimeters alike. For commercial sealant work in Blackheath, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
In Blackheath, as anywhere, the first joints to go are normally the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.
Work in smaller places such as Blackheath tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.
The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Blackheath
Some low prices are low because nothing gets cut out. New sealant laid on old silicone has nothing to bond to, so it peels. Every quote we give includes full removal and preparation, because that’s what makes the new bead last. Around Blackheath, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.
Why appoint us
- One number for every site we cover
- Constructionline member for supplier checks
- Old sealant cut out, never sealed over
- 12 months’ guarantee on every job

Other services in Blackheath
General trades versus a specialist
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
After the work
Keep the joints in good shape with a few simple steps:
- Add sealant to the planned maintenance inspection list
- Look at the sealant around anything that has been moved or replaced
- Act on the first lifting edges rather than waiting
- Keep washroom and kitchen extraction working
Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just ring 01277 525 020 or email the details over for a quote.
Tenants and staff spot black or split sealant quickly, and in a hotel, office or shop it makes the whole space look neglected. Replacing it on a planned cycle keeps complaints down.
Blackheath: questions and answers
Do you cover business parks and estates near Blackheath, such as Broadford Business Park?
Yes. We cover Blackheath and the area around it, including industrial estates, business parks and retail parks such as Broadford Business Park. To start, just give us a call on 01277 525 020 or email us with the unit, the joints involved and your access times.
Will our hotel in Blackheath need to close for the work?
Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.
Can you supply RAMS and insurance details?
Let us know your requirements when you ask for a price. For older buildings we will ask for the asbestos register, plus your site induction rules.
Is it OK to apply fresh sealant over existing beads?
Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Can areas stay open during the work?
It’s mostly about sequence: we agree access windows, phase the work and keep enough facilities open. Let us know what can’t close and we’ll work around it.
What about asbestos in old mastic?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

What Blackheath’s businesses ask us to seal
The South East is one of the drier parts of the UK. Drier doesn’t mean dry every day, so frontage work still has some give in the dates. The 3 miles around Blackheath take in at least three named trading estates, business parks or retail parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.
Refits at hotels like Barnett Hill House Hotel, 0.7 miles south-west of Blackheath, bring joints at vanity tops, bars and reception desks that guests see every day. Parks like Broadford Business Park, 2.1 miles to the west of Blackheath, see tenants come and go, and every move-in brings joints to seal. If you have premises on more than one site, say at Broadford Business Park and The Astolat Industrial Estate, one contractor and one quote can cover both.
