Facade sealing in The Flints, done properly
We don’t install glazing systems or replace glass. We handle the sealant joints that surround those elements: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. Most enquiries involve cold air coming in at window perimeters and staining on stone next to old sealant, on window and door perimeters, cladding panel joints and coping and flashing joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in The Flints, that means joint design, primers and backing rod as standard.
Sites around smaller places like The Flints can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

Different surfaces, different methods
Cladding panel joints
Joints between cladding panels open and close with temperature. We use a product rated for the movement and suited to the panel surface.
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone, with primer where its maker specifies.

Cost factors for facade joints
A fixed quote reflects the actual work. It allows for:
- The size and state of each joint
- Quantities, in metres or numbers
- Removal of failed or old sealant
- Location, for remote and island sites
There’s no price list, since every building and every scope is different. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- Rough lengths or quantities, or drawings if you have them
- Anything awkward about access or site hours
- Asbestos survey details if the building is older
- The postcode of the building
Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Inspect facade joints on a regular cycle
- Note when each elevation was last resealed
- Check the asbestos register before old mastic is disturbed
- Brief window cleaners about newly sealed joints
Following storms, look inside for damp or staining near frames. Catching a new leak early keeps the repair small.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
Our process
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed before the next one starts. Smaller jobs around The Flints can be grouped with others nearby, which keeps travel down. You’ll have a fixed quote before work starts.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Before we start on site

Advice
New build and refits around The Flints
A 2-mile radius around The Flints takes in several hotels. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Rainfall across the South East, The Flints 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 the external programme keeps a little slack.
On a healthcare site such as Keech Hospice Care, which lies west of The Flints, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Building work at universities like University Of Bedfordshire (4.3 miles south-west of The Flints) is often timed for the summer, mastic included. New units and refits on sites such as Butterfield Business Park (1.9 miles south-west of The Flints) need their panel and perimeter joints sealed to the specification.

Questions we’re asked in The Flints
Is The Flints off your patch?
No. Small places get the same service as large ones. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.
Is a hospital such as Keech Hospice Care somewhere you can work?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Do you install glazing systems?
No. That work needs a glazing specialist. We reseal window perimeters, panel joints and frame-to-structure perimeters on commercial buildings.
Do you seal facades in winter?
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, so we plan around the forecast.
Can the building stay open while you work?
Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.
How do we ask for a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photos and a postcode.
Can you find out why a window is leaking?
Yes. We check the sealant joints and report what we find. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
When something else is needed
Honesty saves time and money. Fresh joints won’t solve:
- Damp caused by condensation inside the building
- Arranging specialist high-level access, which is planned with the client
- Installing or repairing glazing systems
If in doubt, speak to us on 01277 525 020 or use the quote form and we will say what we think before you book.
