What sealant work can’t fix
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- A failed roof covering or waterproofing membrane
- Structural cracks or movement the joints weren’t designed for
- Leaks from pipework, wastes or valves (that’s plumbing)
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Sealant applicators in Arnos Grove
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Site teams most often ask us about external beads that have gone brittle and cracked and gaps behind commercial kitchen worktops and sinks, across washrooms and tea points, movement joints in walls and floors and floor and threshold joints. A specialist sealant contractor works differently from a general builder: on jobs in Arnos Grove, preparation and product choice get the time they need.
The most common commercial job in Arnos Grove is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
Much of the planning for a London commercial job is about getting in and out: booked loading, goods-lift times, the permit system and a place to stage materials. With access agreed, we work through the sealant joints a section at a time, keeping disruption to tenants low.
The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

What else we do in Arnos Grove
Surface by surface
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control.
Facade and cladding joints
On a facade, a failed joint is often only visible close up. Photos from a closer viewpoint help us price, with colours confirmed for the product chosen.
Signs you need commercial sealant contractors in Arnos Grove
When a bead peels cleanly off one face, it has failed in adhesion. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.
If one of these sounds familiar, it’s time for a closer look:
- Hardened, chalky sealant on south-facing or exposed elevations
- Expansion joints with the sealant torn out
- Leaks that seem to come through a sealant line
- Shrunken sealant along kitchen worktops and splashbacks
A hotel such as Southgate Hotel London, 1.1 miles north of Arnos Grove, shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

FAQs: Arnos Grove
Do hotels near Arnos Grove have to close for sealant work?
Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we will plan around them.
Do you cover business parks and estates near Arnos Grove, such as Brunswick Industrial Estate?
Yes. Estates, retail parks and business parks around Arnos Grove, Brunswick Industrial Estate among them, are all within reach. To start, just phone 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
Is it OK to apply fresh sealant over existing beads?
Full removal is part of every quote. A bead laid on old silicone peels away.
Can you handle sealant work across several sites?
Yes. We take on runs of jobs across portfolios as well as single sites, priced site by site or as one programme.
What about asbestos in old mastic?
We check the asbestos register or survey before any old sealant is disturbed. Managing asbestos is the dutyholder’s responsibility.
How long does a job like this take?
It depends on the scope, though a typical visit normally takes as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Which site documents can you send us?
We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Every applicator holds a CSCS card.
What sets the cost
The price varies from site to site. It mainly depends on:
- The product specified
- Travel to remote or island sites
- Whether the work must be split into stages
- Any access equipment needed
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we’ll put a fixed figure on it.
What we need to price the job
Whether it’s one area or a whole building, these details speed things up:
- The type of building and who uses it
- Your programme or deadline
- Rough lengths or quantities, or drawings if you have them
- The product your specification calls for
Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.
Why act early in Arnos Grove
Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. In Arnos Grove, each extra visit means more notices, permits and disruption, so cutting the old sealant out fully and doing it right once is the better route.
Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
Why appoint us
- Old sealant cut out, never sealed over
- Colour options checked against the specified product
- Clear, fixed quotes
- Constructionline member
