Facade sealing in Hareplain, done properly
Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds with products suited to facade or glazing perimeter joints. The enquiries we see most involve leaks at window and door perimeters and hard, chalky sealant that no longer flexes, on window and door perimeters, cladding panel joints and stone and brick facade joints. Searching for sealant specialists in Hareplain? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
In the countryside around places like Hareplain, 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 normally what’s needed.
Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Keeping the joints sound
For the best life from the joints:
- Report water ingress at frames as soon as it shows
- Share access with other external trades
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Ask the installer to reseal it properly using a matching sealant.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and if it’s suspected, we stop until it has been tested.
Signs you need facade sealing in Hareplain
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Common reasons buildings call us in:
- Failed seals around shopfront and entrance frames
- Draughts around frames and panels
- Damp patches beside frames after rain
- Failed sealant on precast panel joints
New wings at hospitals like Benenden Hospital (to the south of Hareplain) bring long runs of window and panel joints to seal.

Site staff or a sealant specialist?
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class, which is what makes a joint last.
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. A poor seal in places like these tends to cost more to put right later.
On site: what to expect
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. Jobs in and around smaller places like Hareplain are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Clear stock, furniture or equipment away from the joints
- Send your site hours and access windows
- Send asbestos survey details if the building is pre-2000

Questions about Hareplain
Do you take on work at healthcare sites like Benenden Hospital?
Yes, provided the work is planned with the site’s estates team. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Is Hareplain off your patch?
Not at all. Hareplain is within our area. We cover Greater London and the counties of the South East. Good photos up front let us bring everything on the first visit.
Should we check old sealant for asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Do you install glazing systems?
No. A glazing contractor handles that. What we seal are the joints around frames and panels.
Who decides which product is used?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
Sites and facades in and around Hareplain
Rainfall across the South East, Hareplain included, is lower than in many parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. At about 40 miles from central London, Hareplain is within reach of the capital. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.

What the job involves on each surface
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in.
