Aftercare for building managers
To get the most from the new sealant:
- Log reseals in the O&M or maintenance records
- Report cracked or peeling sealant early
- Check sealant as part of routine building inspections
- Have extract fans checked so wet areas dry out
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them. If that happens, give us a call on 01277 525 020 or email the details over and we will price putting it right.
Sealant rarely fails all at once across a building. A few splits this year typically mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
Commercial sealant contractors for commercial buildings in Finchley
Failed sealant isn’t always the whole story. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. We look before we quote and tell you plainly if sealant won’t solve it, so budgets go where they’ll do some good. The enquiries we see most involve wall and floor joints that have lost their seal and damp patches where an external joint has failed, across kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints. Whoever orders the work in Finchley, the brief is normally the same: a clear scope, tidy work and joints that don’t fail again.
Occupied buildings in Finchley need the work phased: we agree the order with you and hand back each area with its cure time.
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. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Honest limits
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Misted, cracked or failed glazing units (a glazier’s job)
- Old mastic that tests positive for asbestos
- Roof leaks that only look like a joint problem
If you are not sure, just give us a call on 01277 525 020 or send photos by email and we will give you a straight answer before you book.

What the job involves on each surface
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. We cut out mouldy or split beads and reseal in anti-mould sanitary silicone.
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.
Why it’s worth doing now in Finchley
Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. You notice the difference years later, not on the day. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Everything around the joints gets protected before any cutting starts, and the work typically takes anything from part of a day on a short run of joints to several weeks on a large phased package. For a job in Finchley, access comes first: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.

Questions about Finchley
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. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Do you cover business parks and estates near Finchley, such as Finchley Industrial Centre?
Yes, sites like Finchley Industrial Centre are within our area, along with the rest of Finchley. Photos and a short description are enough for a first look.
How is commercial sealant work priced?
Start with whatever information is to hand. We follow up with questions or a visit where needed.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Can you work to our specification?
Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards.
Does the weather affect the work?
It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.
