About our construction mastic in North Street
Site managers want applicators who turn up with the right cards and paperwork. Our applicators are CSCS-carded, and we are CHAS accredited and a Constructionline member. RAMS, an insurance certificate and CSCS details can be confirmed with the quote if you tell us what you need. The enquiries we see most involve sanitary sealant damaged by following trades and old sealant on a refurbishment that needs stripping before new work, across sanitary and kitchen joints, cladding and panel joints and brick and block movement joints. One point of contact handles commercial sealant work in North Street from the first photographs to the final walk-round, for single jobs and planned programmes alike.
In the countryside around places like North Street, conversion schemes put new frames into old stone, flint, brick or timber. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

What the job involves on each surface
Bathrooms, en suites and washrooms
In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly, and any bath is loaded with water first where that’s the agreed method.
Internal decorators’ caulk
Acrylic caulk fills internal gaps around trims, boards and frames ahead of decorating. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.
Why deal with it now?
It helps to bring the mastic subcontractor in before the package is urgent. Early involvement means gaps, products and access are sorted before the programme bites rather than at the snagging stage. Leave it late and they turn up on the snag list. Older rural buildings around North Street move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
Pricing mastic packages depends on quantities, condition and access, plus any specification you’re working to. Ask us for a fixed quote.

Common questions from North Street clients
Is North Street too far out for you?
No. Places such as North Street are covered as much as the big towns. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.
Can being near the sea in North Street affect the sealant we need?
It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.
Can staff carry on working while you are here?
In the majority of cases, yes. We phase the work so most of the building stays in use.
Do you offer coloured sealant?
Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We’ll confirm the colours available for the specified product.
What happens if the weather stops external sealing?
External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work so we normally switch to internal work when that happens.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and the quote will be based on it.
What if there’s asbestos in the old mastic?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.

Sites and facades in and around North Street
The sea is no more than about 1 mile from North Street. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. North Street lies roughly 30 miles out from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For contractors on a campus like University of Greenwich - Medway, 4 miles south-west of North Street, facade and perimeter sealing has to fit around students and term dates.

Signs you need construction mastic in North Street
A joint without backing rod or bond-breaker often fails early. Bonded to the base of the joint and both sides, sealant can’t stretch evenly so we set the depth properly before sealing.
If one of these sounds familiar, it’s time for a closer look:
- Bath and shower joints scraped during the final clean
- Inconsistent sealant finishes from plot to plot
- Frame perimeters left unsealed or poorly sealed
- Early adhesion failures on new external joints
On a healthcare site such as Medway Maritime Hospital, 4.9 miles to the south-west of North Street, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What your quote should include
- Do they follow the manufacturer’s priming guidance?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Their plan for phasing and protecting the area
- Whether their applicators hold CSCS cards
Quoting for work in North Street
The price varies from site to site. Expect it to depend on:
- Whether old sealant has to be cut out first
- Backing rod, priming and other preparation
- Whether the work must be split into stages
- How accessible the joints are
Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
To price the job accurately, we need a clear picture of the site. Useful things to include:
- Specification clauses that apply
- Whether the building will be occupied during the work
- Anything awkward about access or site hours
- Photos of the joints, close up and from further back
The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or give us a call on 01277 525 020 or email us to discuss it first.
