About our facade sealing in Greenhill
External joints face UV, rain, temperature swings and building movement all year, so they don’t last indefinitely. 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. Site teams most often ask us about sealant pulling away from frames or panels and new sealant peeling off old mastic, across cladding panel joints, coping and flashing joints and shopfront frames. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Greenhill is the same: the right product in a properly prepared joint.
On a small site around Greenhill, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

How the job changes by surface
Cladding panel joints
On sealed panel systems, every joint keeps water out. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. Faces are cleaned to sound concrete, and damaged edges are reported first.
Site staff or a sealant specialist?
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
Mastic packages on Greenhill sites
With the shore within about 1 mile, Greenhill counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. Rainfall across the South East, Greenhill included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so external mastic is timed for workable conditions and agreed with the site manager.
Work at a hotel such as The Pier Hotel (to the north-east of Greenhill) tends to be programmed around bookings, mastic included. Building work at universities like University of Kent, 4.8 miles south of Greenhill, is often timed for the summer, mastic included. Recladding or extending a unit at a site like Eddington Business Park, 0.8 miles east of Greenhill, brings panel joints and frame perimeters into the programme.
Greenhill is about 1 mile south-west of Herne Bay, in Kent. We cover commercial sites throughout Greenhill, whether it’s a single job or part of a planned programme. Our Kent coverage takes in 931 places. Sites around London have their own page, about 53 miles away.

Quoting for work in Greenhill
The price varies from site to site. Expect it to depend on:
- How much there is to seal
- How accessible the joints are
- Which sealant the job calls for
- Induction, permit and paperwork requirements
Pricing facade joints depends on how many there are, their condition and the access, plus any specification you are working to. Ask us for a fixed quote.

Why deal with it now?
Scaffold or access already on site makes resealing much simpler. Combine it with planned external works and you only arrange access once. In a smaller place such as Greenhill, getting a contractor back for a second visit takes time, so we’d suggest renewing all the joints that are going, not just the worst.
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Questions we are asked in Greenhill
Could you schedule work at a campus like University of Kent for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Our building in Greenhill is near the coast: does that change the sealant?
It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.
Do you install glazing systems?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
Will rain stop the work?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings.
Can you look at water coming in around a frame?
Yes. Photos help, and you can give us a call on 01277 525 020 or send details through our quote form to arrange a visit. Many frame leaks are sealant failures, though not all, and we will be honest about which it is.
