Leave it or put it right?
A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. Resealing usually costs far less than renewal, and we’ll say so if the frame or fitting is life-expired. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
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.

Commercial mastic work in Seven Sisters
On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). Most enquiries involve layers of sealant, all of them failing and leaks that seem to come through a sealant line, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors. One point of contact handles commercial sealant work in Seven Sisters from the first photographs to the final walk-round, whether it’s one building or several.
Multi-site clients with buildings in and around Seven Sisters can put several sites on one programme, so standards and paperwork match across every site.
For managing agents and FMs looking after premises in Seven Sisters, 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.
Work we carry out comes with a 12-month guarantee. Should something we installed fail, ring 01277 525 020 or email drawings and photos and we’ll come back to it.

From enquiry to sign-off
Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. In Seven Sisters, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We start with the evidence: photographs, drawings or a look on site.
- A fixed quote follows, with removal and preparation included.
- We agree the order of work, access windows and site hours with you.
- The failed sealant comes out and the faces are prepared, with primer where required.
- Depth is set with backing, then the sealant is applied, tooled and the area tidied.
- We hand back each area with its cure time and our 12-month guarantee.
Before we start on site
- Share the asbestos register for older buildings
- Tell us what induction or permit system the site runs
- Have the specification and drawings to hand

Advice
Working on commercial sites near Seven Sisters
There are three care or nursing homes within about 2 miles of Seven Sisters. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound, often in colours that suit the décor. Less than 3 miles from Seven Sisters there are at least three named estates and business parks. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.
Units at retail parks like Tottenham Hale Retail Park (0.6 miles north-east of Seven Sisters) change hands and get refitted, with new joints at every frontage. For premises near Seven Sisters station, less than half a mile west of Seven Sisters, footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at Tottenham Hale Retail Park and Crusader Industrial Park, one contractor and one quote can cover both.

Also close by are Gladesmore Community School (under half a mile east) and Church of St Andrew (0.8 miles south). Seven Sisters has its own railway station: Seven Sisters station. Well-known places in the area include Montfichet's Tower (4.9 miles south) and The Mall Wood Green (1.7 miles north-west). Green spaces nearby include Highgate Hill and Woodberry Wetlands.
Looking after the joints
Keep the joints in good shape with a few simple steps:
- Keep abrasive pads and scrapers off resealed joints
- Log reseals in the O&M or maintenance records
- Have extract fans checked so wet areas dry out
- Put external and wet-area joints on a regular inspection round
Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. If anything looks wrong, ring 01277 525 020 or email drawings and photos with a photo.
Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.
Questions we’re asked in Seven Sisters
Do hotels near Seven Sisters have to close for sealant work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we’ll plan around them.
Can you cope with the access rules in a London building?
Yes, most London buildings have access rules of some kind, and we plan around them. Say when the building is occupied and when it’s quiet, and we will plan accordingly. We allow for the ULEZ, which covers every borough
Do you hold CHAS accreditation?
Yes. We are CHAS accredited and a Constructionline member.

Yes. We cover Seven Sisters, and the simplest way to start is to ring 01277 525 020 or email a schedule or drawings.
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’re CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.
Is your work guaranteed?
Each job sits under our 12-month guarantee from handover. Keeping joints clean and inspected helps them last well beyond that.
How do you keep disruption to occupiers down?
Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing for as long as the cure needs.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Seven Sisters can sit alongside others in a wider programme across Greater London.
Cost factors for sealant joints
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- How accessible the joints are
- Which sealant the job calls for
- How much existing material needs removing
- Working within restricted access windows
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
Details that help us quote
Diagnosis starts before we arrive. Let us know:

- How the joints are reached, and at what height

How the job changes by surface
Washrooms and toilets
Mould that has grown into washroom sealant can’t typically be cleaned out. The lasting answer is removal, preparation and a new sanitary bead, planned so the building keeps enough facilities in use.
Shop fronts and retail fit-outs
Retail work usually has to fit around trading. Tell us your trading hours and access windows and we will plan around them, phasing areas so the shop floor stays usable.
