When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Walls or slabs moving more than any sealant can take
- A failed roof covering or waterproofing membrane
Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.
Joints and surfaces we work on

About our commercial sealant contractors in Cockfosters
Most of the buildings we seal stay open while we’re there. Tell us your site hours and access windows and we’ll plan around them; phased work can also be planned so areas stay in use. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. If you have external beads that have gone brittle and cracked and leaks that seem to come through a sealant line, we can help, whatever the surface. One point of contact handles commercial sealant work in Cockfosters from the first photos to the final walk-round, for single jobs and planned programmes alike.
Multi-site clients with buildings in and around Cockfosters can put several sites on one programme, with one quote format and one point of contact.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, so one job can involve stone, brick, powder-coated frames and laminate in a single visit. The right product goes on each, in a colour chosen to suit where the joint is seen.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Questions about Cockfosters
Does a hotel in Cockfosters need to shut while its sealant is renewed?
Almost never. The work is phased so most rooms stay available. We agree the order of rooms and the timings with you before we start.
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. Share the building’s contractor rules and we’ll work to them. We allow for the ULEZ, which covers every borough
How long will the new sealant last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Do you work directly for building managers?
Yes. Use our quote form to send the site details, or phone or email us, and we will confirm any paperwork you need with the quote.
How do we get a quote?
Send photographs, drawings or a list of locations. If a visit is needed we’ll book one, and a fixed quote follows.
Does the weather affect the work?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
What site paperwork can you provide?
We will confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.
Why deal with it now?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. In many cases the element is fine and only the seal around it has given up. Resealing typically costs far less than renewal, and we will say so if the frame or fitting is life-expired. In Cockfosters, each extra visit means more notices, permits and disruption, so a proper job first time, with the old sealant fully removed, is worth it.
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

Surface by surface
Shop fronts and retail fit-outs
In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. We will confirm the colours available for the specified product.
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we’ll say so before sealing.
What Cockfosters’s businesses ask us to seal
Several hotels sit less than 2 miles from Cockfosters. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading. Cockfosters has four care or nursing homes no more than 2 miles away. Care settings have kitchens, lounges and corridors where joints need to be neat and easy to clean.
Premises within reach of New Barnet station, 0.8 miles west of Cockfosters, often have busy frontages where joints are seen by everyone passing. Refits at hotels like The Hadley Hotel, 1.2 miles west of Cockfosters, bring joints at vanity tops, bars and reception desks that guests see every day. If you have premises on more than one site, say at Hadley Manor Trading Estate and North London Business Park, one contractor and one quote can cover both.

How a job runs
At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. Most London premises stay occupied while we are on site, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- We start with the evidence: photographs, drawings or a look on site.
- You get a fixed quote covering removal, preparation and the new sealant.
- Sequence, access and working times are settled before the first joint is touched.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- Backing goes in, the new sealant is laid and tooled, and the area is left neat.
- We hand back each area with its cure time and our 12-month guarantee.
Preparing the site
- For older buildings, check the asbestos register before work
- Send your site hours and access windows
- Tell staff and tenants when we will be in
Quotes
Send us photos, drawings or a joint schedule and a fixed quote comes back to you. If the job needs a look first, we will arrange a site visit.

Owners, agents and contractors
Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
Main contractors use us as their sealant subcontractor. We work to your programme, your specification and your site rules, with CSCS-carded applicators on site.
Doing it in-house
Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
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.
