How we handle commercial sealant contractors in Colliers Wood
A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface. We work on floor and threshold joints, external facade joints and kitchen worktops and splashbacks, and the failures we’re asked to look at most are messy, uneven beads from earlier work that let the building down and layers of sealant, all of them failing. Facilities teams, main contractors and managing agents in Colliers Wood tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
A lot of what we do in Colliers Wood is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.
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, and where a brand finish matters, the sealant colour is agreed first.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

Why act early in Colliers Wood
Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. Resealing typically costs far less than renewal, though we’ll tell you honestly if the element itself is the problem. In Colliers Wood, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Related advice
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Report cracked or peeling sealant early
- Keep washroom and kitchen extraction working
- Respect the cure time before reopening an area
Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life, while a neutral cleaner and a soft cloth do no harm.
A failed external joint lets water in every time it rains. 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.

Cost factors for sealant joints
There’s no standard rate for sealant work, because every site is different. What we take into account:
- Location, for remote and island sites
- Working within restricted access windows
- The total length or number of joints
- Induction, permit and paperwork requirements
The price depends on how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.
Before you send an enquiry
A few photos plus some basic facts will normally do. It helps to include:
- Approximate linear metres or a joint schedule
- The type of building and who uses it
- Where the site is, with the postcode
- Your programme or deadline
To get a fixed quote, phone 01277 525 020 or email us with the site address and an outline of the work. Our quote form is another easy route.
Should maintenance staff do it?
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, which is what makes a joint last.
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.
