Commercial mastic work in St Paul's Cray
Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. We are commercial sealant applicators for FMs, managing agents, landlords and contractors. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. The enquiries we see most involve untidy joints in a reception, shop floor or lobby and expansion joints with the sealant torn out, on window and door perimeters, washrooms and tea points and external facade joints. A single leaking joint is often how a building in St Paul's Cray first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
If you look after more than one building near St Paul's Cray, the work can be planned as one programme, so standards and paperwork match across every site.
Buildings in a London area such as St Paul's Cray rarely close for maintenance: offices with staff at their desks, shops trading below flats and receptions that can’t be roped off for long. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered
Do you take on jobs in St Paul's Cray where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Is Brook Industrial Estate, near St Paul's Cray, within your area?
Yes. Estates, retail parks and business parks around St Paul's Cray, Brook Industrial Estate among them, are all within reach. Photos and a short description are enough for a first look.
Do you work in St Paul's Cray?
Yes. Sites across St Paul's Cray are covered.
What about asbestos in old mastic?
Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.
Can you take on work for an FM or managing agent?
Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.
What guarantee do you give on resealing?
A 12-month guarantee covers the workmanship from handover. Keeping joints clean and inspected helps them last well beyond that.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
How the job changes by surface
Washrooms and toilets
Black sealant in a toilet block is normally beyond cleaning. Replacement is the fix: strip, clean, dry and reseal, room by room if that suits the building.
Fire-rated seals where specified
Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.
Honest limits
Before quoting, we check that sealant is the right answer. It isn’t the answer for:
- Water from a services leak rather than a joint
- A failed roof covering or waterproofing membrane
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we’ll tell you honestly.

When to call us in St Paul's Cray
Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.
Clients normally get in touch after noticing something like this:
- Frame mastic that has hardened and come away from the wall
- A top-up bead over failed sealant, now lifting
- Weathered facade sealant that no longer flexes
- Leaks that seem to come through a sealant line
Refits at hotels like TLK Apartments & Hotel (to the south-east of St Paul's Cray) bring joints at vanity tops, bars and reception desks that guests see every day.

What St Paul's Cray’s businesses ask us to seal
St Paul's Cray has several hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter. Most London commercial buildings run contractors through a reception, a permit system and booked goods-lift slots. We fit into those systems and phase the work so the building keeps operating.
If you have premises on more than one site, say at Brook Industrial Estate and Nugent Retail Park, one contractor and one quote can cover both. Shops and cafés around stations like St Mary Cray station (to the south of St Paul's Cray) trade from early, so work is timed around them.

Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How a job runs
Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and move on in phases so staff and visitors can carry on around us. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- Every failed bead is removed rather than covered.
- Each joint gets a suitable sealant, laid to depth and tooled.
- A final walk-round, then the 12-month guarantee applies.
What we need from you
- Make sure the joints can be reached
- Explain the parking and delivery arrangements
- Point out any areas we must not close
