Construction mastic in Herne, done properly
Mastic is often where a new building first shows its quality to the client. Untidy or missed joints are among the commonest snag items and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection. If you’re dealing with failed sealant in an existing building being refurbished and new external sealant already peeling away, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Herne is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
For a contractor on a smaller site near Herne, one mastic visit at the right stage saves return trips. Tell us when scaffold comes down and when decoration finishes, and we will plan around those stages.
We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why deal with it now?
On a refurbishment, there’s a choice between resealing existing frames and replacing them. If the frame is in good order, cutting out and resealing the perimeter can be all it needs. We’ll say so if a frame itself is the problem. A failed joint lets water into a building whatever its size. Catching it early means a reseal rather than repairs.
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Snagging before handover
Snagging is often the final mastic stage. Snags are cleared room by room.
Construction mastic around Herne: how the place shapes the job
With the shore within about 2 miles, Herne 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, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. The South East is one of the drier 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.
For contractors at a school such as Herne Church of England Infant School, sealing has to be finished before term starts. Building work at universities like University of Kent, 5 miles to the south-west of Herne, is often timed for the summer, mastic included.

Advice
Common questions from Herne clients
Is Eddington Business Park, near Herne, within your area?
Yes, sites like Eddington Business Park are within our area, along with the rest of Herne. Photos and a short description are enough for a first look.
Will you plan work around the academic year at somewhere like University of Kent?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you come in just for snagging?
Yes. Snag-only work is something we take on.
Will you just go over the old sealant?
No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.
What will the job cost?
Each job is quoted on its own details. To get one, call the office on 01277 525 020 or use the quote form.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Can fire-rated sealing at service penetrations be included?
Where it’s specified, yes to the tested detail. We’ll flag if the detail needs a different product.
Common problems we fix in Herne
Dust is the enemy of adhesion on a construction site. Plaster dust, release agents, protective film residue and damp all stop sealant bonding.
Look out for the following:
- A mastic package split between trades with no clear owner
- Missed perimeter joints on a new elevation
- Cracks opening in caulked internal joints
- Old sealant on a refurbishment that needs stripping before new work
For a contractor working at a hospital such as Queen Victoria Memorial Hospital, 1.2 miles north of Herne, perimeter and facade sealing is planned around patients and deliveries.
What to look for in a quote
- Health and safety accreditation such as CHAS
- Who will actually carry out the work
- How joint depth will be controlled
- Their plan for phasing and protecting the area
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Plan external elevations with the weather in mind
- Ask installers to correct oversized gaps first
- Stick to the specified sealant rather than a generic substitute
- Don’t schedule sealing before decorators and flooring are done
Our 12-month guarantee covers the workmanship from sign-off. The guarantee covers how we sealed, not later damage by other trades.
Frames with gaps too wide for sealant need sorting before the mastic goes on. Sealant stretched over an oversized gap won’t last, so the installer needs to correct it first. We raise them during our first walk of the area.
