Commercial sealant contractors for North Greenwich sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
When it isn’t the sealant
Being straight saves everyone time. New sealant won’t cure:
- Leaks from pipework, wastes or valves (that’s plumbing)
- Faulty windows rather than failed perimeter sealant
- Removing asbestos-containing materials (a licensed or specialist contractor’s job)
If you are not sure, just give us a call on 01277 525 020 or email us and we will give you a straight answer.
What we seal

About our commercial sealant contractors in North Greenwich
Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind, and repeated splits in a movement joint can mean the joint is too narrow for the movement. Part of the job is telling you when the fix is something other than sealant, so nobody pays for a reseal that can’t hold. We work on kitchen worktops and splashbacks, movement joints in walls and floors and washrooms and tea points, and the failures we are asked to look at most are greasy, split joints in a kitchen or tea point and mouldy silicone around WCs, urinals and vanity tops. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in North Greenwich, preparation and product choice get the time they need.
We price commercial jobs in North Greenwich from photographs, drawings or a site visit, and the scope is set out in writing.
In London, most commercial sealant work happens in buildings that stay open: occupied offices, ground-floor retail under residential floors and busy shared entrances. Work is split into zones agreed with the building or facilities manager, so the premises keep working around us.
Every job we finish is backed by a 12-month workmanship guarantee. If our installation lets you down in that time, we return and fix it.

Site staff or a sealant 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.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
When to call us in North Greenwich
A split down the middle of the bead tells a different story. Normally the movement was too much for the sealant chosen. The same product in the same joint tends to fail the same way, so width, depth and product are checked before we quote.
Site and facilities staff are often the first to spot these:
- Black mould through washroom sealant that won’t clean off
- Messy, uneven beads from earlier work that let the building down
- Layers of sealant, all of them failing
- Gaps behind commercial kitchen worktops and sinks
Industrial estates such as Brookmarsh Industrial Estate (to the south of North Greenwich) have offices, trade counters and welfare areas whose sealant ages like any other building’s.
Before you book anyone
- Proof of insurance
- Are they CHAS accredited or on Constructionline?
- Their plan for phasing and protecting the area
- Which product they’ll use, and why it suits the joint
What North Greenwich’s businesses ask us to seal
There are plenty of hotels within about 2 miles of North Greenwich. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. Three care or nursing homes sit less than 2 miles from North Greenwich. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms; colours can be chosen to suit the interior.
Shops and cafés around stations like Greenwich station (0.8 miles south of North Greenwich) trade from early, so work is timed around them. Occupiers with premises at both Brookmarsh Industrial Estate and Greenwich Centre Business Park could have the sealant at each handled under one quote.
North Greenwich is about 1 mile north-west of Greenwich, in Greater London. Commercial clients in North Greenwich use us for work on sealant joints, as part of our coverage of Greater London. North Greenwich is one of 764 places we cover in Greater London for sealant joints.

If your building is just outside North Greenwich, we cover Isle of Dogs (1 mile south-east), Millwall (1 mile west), Cubitt Town (1 mile north-east), Deptford (1 mile south-west) and Greenwich (1 mile south-east). Further afield, our area takes in London (3 miles west), City of Westminster (6 miles west), Marylebone (6 miles west), Kensington (8 miles west), St Pancras (5 miles north-west) and Shoreditch (4 miles north-west).
Local landmarks in North Greenwich
Locally, jobs take us to sites close to Laban Centre, Canary Wharf College 3 and St. Paul's, among other places. Also close by are Mudchute Park and Farm (under half a mile north-east) and The Ferry House Public House (less than half a mile south-east). The nearest railway station is Greenwich station, roughly 0.8 miles south. Well-known places in the area include Old Royal Naval College (0.7 miles south-east) and Greenwich Castle (1.1 miles south-east). For a walk, there’s Sue Godfrey Nature Park and Tower Hill.
Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Ask cleaners to use a soft cloth and mild cleaner on sealant
- Check the asbestos register before anyone disturbs old sealant in an older building
- Keep washroom and kitchen extraction working
- Keep barriers up until the new sealant has cured
In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, and mould follows damp. Your maintenance team can look at extract fans at the same time.
Sealant rarely fails all at once across a building. A few splits this year usually mean more next year. We can assess the lot and suggest what to do now and later.
Diagnose, treat, sign off
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before we move to the next. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
- 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.
Getting the site ready
- Agree which areas must stay open
- Send any specification or drawings in advance
- Share your working hours and any access restrictions

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, and we’ll tell you if the detail calls for something else.
Shop fronts and retail fit-outs
Most shops can’t close for a reseal. Tell us your trading hours and access windows and we will plan around them, working in sections where that helps.
Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Will our hotel in North Greenwich need to close for the work?
Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.
Is it fine to apply new sealant on top of old?
No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Does the weather affect the work?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.
How many days will you need on site?
We plan the time on site around your programme and access. You will have an expected duration with the quote.
What site paperwork can you provide?
We confirm documents at quote stage: most clients ask for RAMS, our insurance certificate and CSCS details. Our applicators are CSCS-carded.
How do you choose the sealant?
A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
