About our commercial sealant contractors in Plumstead
Some sealants used before 2000 can contain asbestos, so older stock needs a check first. We ask to see the asbestos register or survey before old sealant is disturbed, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested, and we don’t remove asbestos-containing materials ourselves. Site teams most often ask us about shrunken sealant along kitchen worktops and splashbacks and weathered facade sealant that no longer flexes, on window and door perimeters, movement joints in walls and floors and external facade joints. For commercial sealant work in Plumstead, you deal with one contact from quote to sign-off, whether it’s one building or several.
If you look after more than one building near Plumstead, the work can be planned as 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, which means one visit can cover joints against stone, brickwork, coated aluminium and shop-fit panels. Each surface gets its own preparation and, where it’s seen, a sealant colour that sits with it.
Every job we finish is backed by a 12-month workmanship guarantee, in Plumstead as everywhere else we work. If our installation lets you down in that time, we return and fix it.

When something else is needed
Not every problem is a sealant problem, and we are upfront when that’s the case. These need a different solution:
- Walls or slabs moving more than any sealant can take
- Leaking roofs, gutters or flat-roof membranes (those need a roofer)
- Leaks from pipework, wastes or valves (that’s plumbing)
Not sure which it is? You can speak to us on 01277 525 020 or email the details over and we’ll tell you honestly before you book.

Common questions from Plumstead clients
Does your area include sites such as Gateway Business Centre, near Plumstead?
Yes, sites like Gateway Business Centre are within our area, along with the rest of Plumstead. A few photos and the unit address let us price the work.
Must a hotel around Plumstead close while you work?
Rarely, if ever. We take a few rooms out at a time. Tell us your quiet periods and access windows and we will plan around them.
How do you keep disruption to occupiers down?
Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
Could the old sealant in an older building contain asbestos?
In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.
Are your applicators CSCS-carded?
Yes. Our applicators hold CSCS cards, which many sites require.
Is the old sealant taken out first?
Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.
How a job runs
When we get to site, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before any cutting starts, and the work usually takes part of a day on a small job and longer where several buildings or phases are involved. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. If there’s a loading bay, a car park or a permit we can use, tell us when you send details.
- We start with the evidence: photos, 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.
Preparing the site
- Tell us what induction or permit system the site runs
- Tell staff and tenants when we’ll be in
- Confirm the product named in the specification

Looking after the joints
Sealant joints are maintenance items, and their life depends on movement, exposure, cleaning and use. We suggest:
- Keep washroom and kitchen extraction working
- Deal with small splits before they become leaks
- Brief cleaning contractors to avoid scourers and blades on sealant
- Keep barriers up until the new sealant has cured
Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them and the joint gets left open. If that happens, give us a call on 01277 525 020 or send photos by email and we’ll price putting it right.
In kitchens and washrooms, a failed joint is a cleaning problem as well as a leak risk. Cleanability is something environmental health officers pay attention to, so sound, smooth joints matter.
Do you need commercial sealant contractors in Plumstead?
Outside, sunlight and rain wear sealant down year after year. UV hardens the surface while wind and rain work at the edges; in time the surface chalks, hardens and cracks. A hardened bead can’t follow the building any more.
Clients usually get in touch after noticing something like this:
- Earlier reseals applied straight onto the failed bead
- Untidy joints in a reception, shop floor or lobby
- Wall and floor joints that have lost their seal
- Frame mastic that has hardened and come away from the wall
On a business park such as Gateway Business Centre, less than half a mile to the north of Plumstead, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
What to look for in a quote
- Do they follow the manufacturer’s priming guidance?
- Their public liability cover
- How the existing material will be dealt with
- Which product they’ll use, and why it suits the joint

What the job involves on each surface
Commercial kitchens and tea points
Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.
Washrooms and toilets
Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.
What Plumstead’s businesses ask us to seal
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We plan around them and agree phasing so tenants and customers aren’t disrupted. A 2-mile radius around Plumstead takes in a number of hotels. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, and the work can be phased so the rest of the hotel keeps trading.
For a hotel such as Gallions Hotel, 1.4 miles to the north of Plumstead, the colour of a joint at the bar or the bath matters to the look of the room. Shopping centres and retail parks such as Gallions Reach Shopping Park, 1.6 miles to the north of Plumstead, see a steady turnover of shop fits, each leaving joints where colour and finish matter.
