About our commercial sealant contractors in Harringay
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, then both faces are cleaned back to sound, dry material with no dust or grease on them. Where the sealant maker specifies a primer for that substrate, it goes on before the new bead. If you have greasy, split joints in a kitchen or tea point and earlier reseals applied straight onto the failed bead, we can put it right, whatever the surface. Most enquiries from Harringay start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.
If you look after more than one building near Harringay, the work can be planned as one programme, so standards and paperwork match across every site.
For managing agents and FMs looking after premises in Harringay, access is normally the first question: booked loading, goods-lift times, the permit system and a place to stage materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Questions about Harringay
Can you work in a London building with booked loading and goods-lift slots?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Share the building’s contractor rules and we will work to them. The ULEZ covers the whole of Greater London, which we allow for
Is Arena Shopping Park, near Harringay, within your area?
Yes. Estates, retail parks and business parks around Harringay, Arena Shopping Park among them, are all within reach. Photos and a short description are enough for a first look.
Can you take on work for an FM or managing agent?
Yes, and through main contractors too. We quote, schedule and report back in the way that suits your process.
How is commercial sealant work priced?
Photos, drawings or a schedule of the joints are normally enough to start through our quote form. Where we need to see it, we will arrange a site visit, then send a fixed quote.
Can one contractor look after sealant on all our buildings?
Yes. We regularly take on multi-site work and planned maintenance programmes, quoted per building or as a package.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you work to architects’ specifications?
Yes. The specification and the manufacturer’s installation guidance are what we work to.

How a job runs
Site rules come first: sign-in, induction and whatever permit system the building uses. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Planning a London job such as one in Harringay starts with access. Send the building rules and access times with your enquiry.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- 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.
What we need from you
- Tell us your opening times and when work is allowed
- Have the specification and drawings to hand
- Clear stock, furniture or equipment away from the joints
Getting a fixed quote
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.
Advice
What sealant work can’t fix
Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:
- Broken glass or blown double-glazed units
- A failed roof covering or waterproofing membrane
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If you are not sure, just call 01277 525 020 or use the quote form and we will give you a straight answer before you book.
Surfaces we seal
- Kitchen worktops and splashbacks
- Washrooms and tea points
- Movement joints in walls and floors
- Floor and threshold joints
- External facade joints
- Window and door perimeters
Signs you need commercial sealant contractors in Harringay
External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges, so beads chalk, stiffen and lose their stretch. A hardened bead can’t follow the building any more.
Any of the following is a good reason to get the joints checked over:
- Water staining near frames, panels or ceilings
- Mouldy silicone around WCs, urinals and vanity tops
- Messy, uneven beads from earlier work that let the building down
- Layers of sealant, all of them failing
If you have premises on more than one site, say at Arena Shopping Park and Crusader Industrial Park, one contractor and one quote can cover both.
What to look for in a quote
- What level of public liability insurance do they hold?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Whether their applicators hold CSCS cards
- What the guarantee covers, and for how long
Owners, agents and contractors
For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules, and our applicators hold CSCS cards.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.

Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes. At least three named trading, business or retail sites lie within about 3 miles of Harringay. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

For a retailer at a site such as Arena Shopping Park, under half a mile to the south of Harringay, the joints customers see are as much part of the fit-out as the shelving.

Different surfaces, different methods
Window and door perimeters
The perimeter joint between a frame and the structure keeps rain out of the reveal. Failed perimeters are cut out and cleaned, backing goes into deeper gaps, and the joint is resealed with a low-modulus neutral-cure silicone or another suitable product.
Movement joints in walls and floors
Floor joints that take trolleys or forklifts need a tougher filler or sealant. We’ll recommend the right filler or sealant for the traffic and movement; if the arrises are broken, we’ll say so before sealing.
General trades versus a specialist
Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
