Commercial sealant contractors in St Mary Cray, done properly
Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we will plan around them. That applies whether the building is an office, a shop, a hotel, a college or a care home. Most enquiries involve shrunken sealant along kitchen worktops and splashbacks and leaks that seem to come through a sealant line, on external facade joints, kitchen worktops and splashbacks and floor and threshold joints. For commercial sealant work in St Mary Cray, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
If you look after more than one building near St Mary Cray, the work can be planned as one programme, so standards and paperwork match across every site.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Keeping the joints sound
Regular inspection catches problems early. Specifically:
- Put external and wet-area joints on a regular inspection round
- Log reseals in the O&M or maintenance records
- Look at the sealant around anything that has been moved or replaced
- Act on the first lifting edges rather than waiting
Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just ring 01277 525 020 or send details through our quote form for a quote.
Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Your questions answered
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we will work to them.
Do hotels near St Mary Cray have to close for sealant work?
In most cases no closure is needed: we work room by room or floor by floor. The plan is built around your bookings.
Does commercial sealant work come with a guarantee?
The work is guaranteed for 12 months. Should anything we did fail within that period, let us know.
Does the weather affect the work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.
Can one contractor look after sealant on all our buildings?
Yes, within the areas we cover: South East England, Greater London and Scotland. Each site gets the same process and a single contact.
Could the old sealant in an older building contain asbestos?
Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested. HSE guidance on asbestos is a useful reference.
Do you seal on top of existing sealant?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Why deal with it now?
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. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
The specified product makes a difference, as does the preparation each joint needs, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.
Why us?
- Old sealant cut out, never sealed over
- Standard and matched colours in many product ranges
- CSCS-carded applicators
- CHAS accredited contractor

Signs you need commercial sealant contractors in St Mary Cray
Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade all let go sooner than they should. BS 6213 gives guidance on choosing construction sealants.
Common reasons buildings call us in:
- Smeared sealant across finishes from a rushed job
- Movement joints packed with grit and debris
- Mouldy silicone around WCs, urinals and vanity tops
- Hardened, chalky sealant on south-facing or exposed elevations
Sites a few miles apart, such as Halo Business Park and Nugent Retail Park, can share one programme and one point of contact.
What your quote should include
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
- Their public liability cover
- Do they follow the manufacturer’s priming guidance?
When to bring in a specialist
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
From enquiry to sign-off
In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then handed back before we move to the next. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Send details through our quote form, or ask for 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.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- We check the work with you, and the 12-month guarantee starts.
Preparing the site
- Tell staff and tenants when we will be in
- Share the asbestos register for older buildings
- Point out parking and an unloading spot
