Looking after the joints
Cleaning and maintenance staff play a part too. Pass these on to them:
- Have extract fans checked so wet areas dry out
- Respect the cure time before reopening an area
- Check joints after other trades have worked nearby
- Keep a record of which joints were resealed and when
Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. Should something look amiss, you can give us a call on 01277 525 020 or email us and send a picture.
Sealant installed at the same time typically fails in sequence. A few splits this year usually mean more next year, so it makes sense to look at the wider elevation or block. We can assess the lot and suggest what to do now and later.
Sealant applicators in Merton Park
How long a joint lasts is decided before any sealant leaves the gun. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. Most enquiries involve damp patches where an external joint has failed and expansion joints with the sealant torn out, on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Merton Park is the same: the right product in a properly prepared joint.
If you look after more than one building near Merton Park, the work can be planned as one programme, so standards and paperwork match across every site.
Much of the planning for a London commercial job is about getting in and out: loading bay slots, goods lifts, permits to work and somewhere to keep materials. Once that’s settled, the sealant joints are resealed in sections so tenants are disturbed as little as possible.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Surface by surface
Shop fronts and retail fit-outs
Shop fits put sealant right in front of customers. Counters, display units, shopfront frames and floor trims all need a neat line, often in a colour to suit the brand finish. We will confirm the colours available for the specified product.
Fire-rated seals where specified
Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.
Work for main contractors and building owners
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.
Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.
From enquiry to sign-off
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, with the work itself typically taking as long as the agreed scope needs, from a single visit to a programme spread over several weeks. Planning a London job such as one in Merton Park starts with access. Send the building rules and access times with your enquiry.
- 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.
- Sequence, access and working times are settled before the first joint is touched.
- The failed sealant comes out and the faces are prepared, with primer where required.
- 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
- Send your site hours and access windows
- Have the specification and drawings to hand

General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Shops, offices and hotels in and around Merton Park
In London, commercial buildings often have managed loading bays, goods lifts and permit-to-work systems. We work within them, one zone at a time. Merton Park has a good number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes, with rooms done in turn while the rest stay let.
A business with units at Nelson Trading Estate and Lombard Business Park needn’t use two contractors for its sealant. For a job in Merton Park, we confirm the ULEZ-compliant vehicle, the loading arrangements and where materials go before we arrive. A unit on an estate like Nelson Trading Estate (to the north-east of Merton Park) usually has an office front, a trade counter and staff facilities with joints of their own.

What else we do in Merton Park
Merton Park: questions and answers
Is Nelson Trading Estate, near Merton Park, within your area?
Yes. We cover Merton Park and the area around it, including industrial estates, business parks and retail parks such as Nelson Trading Estate. A few photographs and the unit address let us price the work.
Do hotels near Merton Park 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 weather delay the job?
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.
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 if something is suspected, work stops until it’s tested.
What do you need from us to quote?
Start with whatever information is to hand. We follow up with questions or a visit where needed.
Is your work guaranteed?
It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we will look at it.
Can one contractor look after sealant on all our buildings?
Yes. Send a list of addresses and what’s needed at each, and we will put together a fixed quote and a sensible order of work.
