Photos, a specification or a quick description of the joints is enough to start a fixed quote.
How a job runs
We bring the products specified for the job, along with primers and backing rod. 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. In Belmont, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Areas are handed back as each section is finished.
- You send photos, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
- We work out why the joints have failed and fix a quote for the agreed scope.
- Before anything is cut out, we agree access, timings and sequence.
- We strip the failed bead and prepare both faces of the joint.
- We fit backing to the right depth, prime where specified and lay the new bead.
- We walk the completed areas with you and sign them off under the 12-month guarantee.
Preparing the site
- Send any specification or drawings in advance
- Make sure the joints can be reached
- Share your working hours and any access restrictions

How we handle commercial sealant contractors in Belmont
How long a joint lasts is decided before any sealant leaves the gun. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. Site teams most often ask us about earlier reseals applied straight onto the failed bead and untidy joints in a reception, shop floor or lobby, on washrooms and tea points, movement joints in walls and floors and floor and threshold joints. Looking for mastic applicators who cover Belmont? We’ve been sealing commercial buildings since 2005.
The most common commercial job in Belmont is resealing joints that have simply reached the end of their life: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
Buildings in a London area such as Belmont rarely close for maintenance: 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.
Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

When to bring in a specialist
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Questions we’re asked in Belmont
Does a hotel in Belmont need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
Can you cope with the access rules in a London building?
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. All of Greater London is inside the ULEZ, and our planning allows for it
Can you work to our specification?
Yes. Send it with your enquiry, and we will price the work to it.
What about asbestos in old mastic?
On older buildings, our first request is the asbestos survey. The duty to manage asbestos sits with the dutyholder.
Which sealant will you use?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.

Different surfaces, different methods
Washrooms and toilets
Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.
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.

Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor.

Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Put external and wet-area joints on a regular inspection round
- Note dates and locations of sealant work for future planning
- Check the asbestos register before anyone disturbs old sealant in an older building
- Keep barriers up until the new sealant has cured
Add the resealed joints to your planned maintenance inspections. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, ring 01277 525 020 or send photos by email with a photo.
Occupiers often notice failing sealant before the facilities team does. Planned replacement saves fielding the same complaint again and again.
