How the job changes by surface
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first, and we will mention any edges that need repair.
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
Facade sealing in High Halstow, done properly
External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When the time comes, we cut the old sealant out completely and start again. We work on cladding panel joints, shopfront frames and window and door perimeters, and the usual reasons a site gets in touch are unsightly perimeter sealant on a visible elevation and failed sealant on precast panel joints. Most enquiries from High Halstow start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Sites around smaller places like High Halstow can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photos and the programme and we will quote to suit.
We stand behind the joints we seal with a 12-month guarantee. That covers our preparation and application, and we come back if anything isn’t right.

Keeping the joints sound
Problems stay small when the joints are checked regularly. Specifically:
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
- Insist on a full cut-out when joints are renewed
- Brief window cleaners about newly sealed joints
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
Building and refurbishing in High Halstow
High Halstow is within about 3 miles of the coast. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. High Halstow lies roughly 29 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.
On a campus such as University of Greenwich - Medway, which lies south of High Halstow, new teaching buildings and residences are usually built and refurbished around the academic year. For contractors at a school such as High Halstow Primary Academy, sealing has to be finished before term starts. New wings at hospitals like Medway Maritime Hospital (5 miles south of High Halstow) bring long runs of window and panel joints to seal.
High Halstow is about 5 miles south of Canvey Island, in Medway. We cover High Halstow and the rest of Medway, and jobs here get the same fixed quote and 12-month guarantee as anywhere else. We work across 54 places in Medway. There’s a separate page for London, about 29 miles away.

What sets the cost
There’s no standard rate for sealant work, because every site is different. What we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Induction, permit and paperwork requirements
- Any access equipment needed
- Distance, for remote addresses
Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.
What we need to price the job
There’s no need for a formal survey. These details are enough to start:
- Clear photos of the problem areas
- The product your specification calls for
- Asbestos survey details if the building is older
- Drawings or a marked-up plan, if available
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
On site: what to expect
We follow your site rules from the start: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. For a building around High Halstow, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- Explain the parking and delivery arrangements
- Tell us your opening times and when work is allowed
- Tell us which areas need to stay in use

Your questions answered
Do you take on work at healthcare sites like Medway Maritime Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Could you schedule work at a campus like University of Greenwich - Medway for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing and we follow the specified product.
How much does the work cost?
It depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Do you install glazing systems?
No. Glazing, windows and glass replacement aren’t part of our work. We seal the joints around them, such as perimeter joints where frames meet the structure.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Commercial clients in High Halstow
We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Sites in High Halstow can sit alongside others in a wider programme.
Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, and our applicators hold CSCS cards.
Why deal with it now?
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Around High Halstow, it’s better to renew all the failing joints at once. Photos of every joint help us quote for the whole job.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What you get with us
- Public liability insurance in place
- Colour agreed before work starts
- One contact handling all your sites
- A range of standard colours, depending on the product
