Commercial sealant contractors in Old Town, done properly
Pricing a commercial reseal is a short process. Our quote form takes photographs, drawings or a schedule of the areas; you can also call 01277 525 020 or use the quote form with the details. If the joints need seeing in person, a site visit comes first, and a fixed quote for the agreed scope follows. We work on kitchen worktops and splashbacks, movement joints in walls and floors and window and door perimeters, and the usual reasons a site gets in touch are damp patches where an external joint has failed and a top-up bead over failed sealant, now lifting. Whether you call it commercial sealant work, mastic application or joint sealing, in Old Town it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
A lot of what we do in Old Town is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.
In London, most commercial sealant work happens in buildings that stay open: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Keeping the joints sound
After handover, these steps help:
- On pre-2000 buildings, share the asbestos information before work starts
- Act on the first lifting edges rather than waiting
- Make sure ventilation in wet areas is switched on and working
- Note dates and locations of sealant work for future planning
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life.
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. Resealing early keeps the problem in the sealant and out of the building.
When to call us in Old Town
No sealant joint is permanent. How long one lasts depends on the movement it takes, its exposure to sun and weather, the cleaning regime, the traffic and the product itself. In commercial buildings those factors tend to act together, which is why regular inspection pays.
Site and facilities staff are often the first to spot these:
- Damp patches where an external joint has failed
- Black mould through washroom sealant that won’t clean off
- Layers of sealant, all of them failing
- Movement joints packed with grit and debris
Premises within reach of West Croydon station, under half a mile north of Old Town, often have busy frontages where joints are seen by everyone passing.
What your quote should include
- How they handle RAMS and site documents
- Is the sealant right for the movement and the substrate?
- How long is the guarantee, and what does it include?
- How the joint faces will be prepared and primed
Owners, agents and contractors
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
Your questions answered
Do you take on jobs in Old Town where loading and access are tightly controlled?
Yes, most London buildings have access rules of some kind, and we plan around them. The building manager’s rules go straight into our method.
Is Pilton Industrial Estate, near Old Town, within your area?
Yes, sites like Pilton Industrial Estate are within our area, along with the rest of Old Town. A few photographs and the unit address let us price the work.
Could the old sealant in an older building contain asbestos?
It’s possible in older buildings, especially those built before 2000. We ask to see the asbestos register or survey before disturbing old sealant, and if something is suspected, work stops until it’s tested.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Do you cover Old Town?
Yes. Old Town falls within our area, and you can call the office on 01277 525 020 or email a schedule or drawings to get started.
What sealant work can’t fix
Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Broken glass or blown double-glazed units
- Old mastic that tests positive for asbestos
If in doubt, call the office on 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Shops, offices and hotels in and around Old Town
Contractor rules in London buildings can be strict, with inductions, permits and timed loading all normal. We fit into those systems and phase the work so the building keeps operating. Four care or nursing homes sit less than 2 miles from Old Town. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean.
In hotels such as Leonardo Hotel London Croydon, less than half a mile north-east of Old Town, refurbishments typically mean bathroom, bar and reception joints where a matched sealant colour has to sit with the finishes. Trade counters and showrooms on estates such as Pilton Industrial Estate, under half a mile to the north of Old Town, need neat joints where clients see them.

What else we do in Old Town
From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and the sealant is tooled off neatly. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send 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.
- Where parts of the building must stay open, the work is phased.
- Every failed bead is removed rather than covered.
- A suitable product for each joint goes in at the right depth and is tooled.
- A final walk-round, then the 12-month guarantee applies.
