Facade sealing for Mott's Mill sites
Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
Our process
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. Jobs in and around smaller places like Mott's Mill are usually planned as a single visit, so we ask for photographs and rough sizes first. 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.
Getting the site ready
- Send any specification or drawings in advance
- Tell staff and tenants when we will be in
- Arrange parking or a loading space
Quotes
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.

Facade sealing for commercial buildings in Mott's Mill
Sealant around windows, doors and cladding panels stops rain reaching the wall behind. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints, and the usual reasons a site gets in touch are perimeter sealant that has split or peeled away and perimeter joints where frames meet the structure. A single leaking joint is often how a building in Mott's Mill first comes to us: we look at the rest while we’re there and tell you what we find.
In the countryside around places like Mott's Mill, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
A 12-month guarantee applies to all our work. If an installation problem shows up, ring 01277 525 020 or send details through our quote form and we will arrange a return visit.

When to call us in Mott's Mill
When the sealant tears down its centre, it has usually been asked to move more than it can. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
What tends to prompt an enquiry:
- Perimeter sealant that has split or peeled away
- Failed sealant on precast panel joints
- Damp patches beside frames after rain
- Air leaks through failed facade joints
On a healthcare site such as Crowborough War Memorial Hospital, which lies south of Mott's Mill, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Questions to ask before you book
- Whether primer will be used where the manufacturer specifies it
- Which product they’ll use, and why it suits the joint
- How they’ll work around occupants
- Their pre-qualification and accreditations
After the work
Regular inspection catches problems early. In particular:
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
- Keep the sealant details on the building file
- Investigate damp beside windows promptly
Blocked sills and gutters push water at the joints. Good drainage keeps water moving off the facade rather than sitting against the joints.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. A well-designed joint lasts longer than a like-for-like copy of a failed one.
Common questions from Mott's Mill clients
Does your area include sites such as Crowborough Business Park, near Mott's Mill?
Yes, sites like Crowborough Business Park are within our area, along with the rest of Mott's Mill. Photos and a short description are enough for a first look.
Will you plan work around the academic year at somewhere like Canterbury Christ Church University - Salomons?
Yes, holiday working periods are the norm on campus jobs. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Is Mott's Mill in your area?
Yes. Mott's Mill falls within our area, and you can call 01277 525 020 or email us to get started.
Is old mastic on our building likely to contain asbestos?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. The dutyholder’s asbestos register should be checked first; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
Can you work on upper floors?
That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we will plan the work with you.
Do you guarantee your work?
Yes. Our workmanship is backed for 12 months.
Can you find out why a window is leaking?
Yes. We check the sealant joints and report what we find. If the water seems to come from a roof, sill or the glazing unit instead, we say so.

Why it’s worth doing now in Mott's Mill
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing early costs far less than repairing what the water reaches. One visit to deal with every failing joint makes more sense than several trips to a place like Mott's Mill, rather than one at a time. Photos of every joint help us quote for the whole job.
What a job costs comes down to how many linear metres there are, how much old material needs removing and the access. Call for a quote once you have the details.

- Matching to RAL references, product permitting
- Fully insured, including public liability cover
- Old sealant cut out, never sealed over

Facade sealing in Mott's Mill: the local picture
Mott's Mill sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. At about 30 miles from central London, Mott's Mill is within reach of the capital. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
When a school such as Groombridge St Thomas' Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. New units and refits on sites such as Crowborough Business Park (2.5 miles south of Mott's Mill) need their panel and perimeter joints sealed to the specification.

Honest limits
A few problems need another trade or a different fix, and we point that out rather than sealing over them:
- Work on the window or framing system itself
- Arranging specialist high-level access, which is planned with the client
- Leaks from roofs, gutters or failed flashings rather than sealant joints
If in doubt, ring 01277 525 020 or send photos by email and we’ll say what we think.
