What the job involves on each surface
Fire-rated seals where specified
Fire-rated sealant is only one type of fire-stopping product. Collars, wraps, batts and boards are specified for other services and gaps, so we will flag it if the detail needs a different product.
Movement joints in walls and floors
A trafficked floor joint needs a different product from a wall joint. We will recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.
Sealant applicators in Edmonton
Pricing a commercial reseal is a short process. Our quote form takes photographs, drawings or a schedule of the areas and you can also ring 01277 525 020 or email the details over to talk it through. If the joints need seeing in person, a site visit comes first, and a fixed quote for the agreed scope follows. We work on movement joints in walls and floors, floor and threshold joints and kitchen worktops and splashbacks, and the failures we are asked to look at most are window and door perimeter joints that have cracked open and weathered facade sealant that no longer flexes. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Edmonton is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
The most common commercial job in Edmonton is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.
London’s commercial stock mixes period buildings turned into offices with modern glass and steel, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. The right product goes on each, in a colour chosen to suit where the joint is seen.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Why it’s worth doing now in Edmonton
On many buildings the mastic was done by whichever trade was on site. A specialist applicator takes care of product choice, joint depth and preparation, and they’re where most failures begin. You notice the difference years later, not on the day. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.
A quote for sealant joints depends on quantities, condition and access. Ask us for a fixed quote.

Quoting for work in Edmonton
To price the job, we consider:
- The total length or number of joints
- Travel to remote or island sites
- Induction, permit and paperwork requirements
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.
What we need to price the job
We can often quote from photos and a few details. Please tell us:
- The asbestos register, for older buildings
- Any dates the work must fit around
- What the building is and how it’s used
- Photos of the joints, close up and from further back
Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed, then handed back before the next one starts. In Edmonton, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Phased work keeps the rest of the building in use.
- Site photos, drawings or a visit tell us what’s there and how it has failed.
- You get a fixed quote covering removal, preparation and the new sealant.
- 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
- For older buildings, check the asbestos register before work
- Agree which areas must stay open
- Move anything stored against the joints

Advice
Shops, offices and hotels in and around Edmonton
London premises usually come with a building manager, booked loading and house rules for contractors. Our planning starts from those rules rather than working round them later. There are five care or nursing homes within about 2 miles of Edmonton. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound.
A business with units at Edmonton Green Shopping Centre and Dominion Business Park needn’t use two contractors for its sealant. With Edmonton inside the ULEZ and kerb space scarce, we sort access and loading before the first day on site. For premises near Edmonton Green station, under half a mile north-west of Edmonton, footfall is part of the plan: work is phased so shops and offices keep trading.
Edmonton is about 9 miles north-east of City of Westminster, in Greater London. Across the N9 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. Our Greater London coverage takes in 764 places. London is covered too, around 9 miles from Edmonton.
Business premises anywhere in N9, N18, N13 and EN1 are within our area for sealant joints. We cover commercial and managed buildings on The Broadway, Plevna Road and Galahad Road. Being close to the B137 and B154, Edmonton is straightforward for us to reach. Nearby places we also cover include Upper Edmonton (1 mile south), Picketts Lock (1 mile east), Northumberland Park (1 mile south), Ponders End (1 mile north-east) and Bush Hill Park (1 mile north-west) for sealant joints. Further afield, our area takes in London (9 miles south), City of Westminster (9 miles south-west), Marylebone (8 miles south-west), Kensington (10 miles south-west), St Pancras (7 miles south) and Shoreditch (7 miles south).
Near you in Edmonton
Around Edmonton, our work takes us to commercial buildings near NiW Furniture pub, The Latymer School and Starks Field School, among other places. Edmonton has its own railway station: Edmonton Green station. Nearby you will also find Edmonton Green Shopping Centre (less than half a mile north-east) and North Middlesex University Hospital (1 mile south-west). For a walk, there’s Highams Park Lake and Ainslie Wood.
When something else is needed
Our job is the joint, not everything around it. Sealant alone won’t deal with:
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Structural cracks or movement the joints weren’t designed for
If in doubt, ring 01277 525 020 or use the quote form and we’ll say what we think before you book.
Joints and surfaces we work on
- Window and door perimeters
- External facade joints

Building owners, agents and FMs in Edmonton
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.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.
FAQs: Edmonton
Can you work in a London building with booked loading and goods-lift slots?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method.
Will you take on work at estates like Edmonton Green Shopping Centre, close to Edmonton?
Yes. Our area takes in Edmonton and its surroundings, with estates and business parks such as Edmonton Green Shopping Centre included. To start, just give us a call on 01277 525 020 or email the details over with the unit, the joints involved and your access times.
Do you hold CHAS accreditation?
Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.
Does weather matter for sealant work?
It can, when the joints are outside. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
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.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
How soon can the area be used again?
We’ll confirm how long the chosen product needs to cure, and sign any area that should be left alone.
