Facade sealing in Cotman's Ash
Some clients need every window on a block resealed; others need a few leaking frames sorted. Either way, the method is the same: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. We work on window and door perimeters, perimeter joints where frames meet the structure and shopfront frames, and what we are called in for most is draughts around frames and panels and new sealant peeling off old mastic. A single leaking joint is often how a building in Cotman's Ash first comes to us: we look at the rest while we’re there and tell you what we find.
Around smaller places like Cotman's Ash, building work typically means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why it’s worth doing now in Cotman's Ash
If access is already up for other work, resealing at the same time makes sense. Coordinating facade sealing with other external works avoids paying for access twice. Older rural buildings around Cotman's Ash move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.

Your questions answered
Does your area include sites such as Chaucer Business Park, near Cotman's Ash?
Yes. Estates, retail parks and business parks around Cotman's Ash, Chaucer Business Park among them, are all within reach. A few photos and the unit address let us price the work.
Do you take on work at healthcare sites like Sevenoaks Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Do you have public liability insurance?
Yes. We’re fully insured, and the certificate can go with your quote.
Can you quote from photographs?
That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Do you guarantee your work?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
Who decides which product is used?
If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
When is resealing likely to be due?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Cost factors for facade joints
Before we quote, we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Site requirements such as inductions and permits
- The total length or number of joints
- Backing rod, priming and other preparation
There’s no price list, because the scope varies so much from one building to the next. Call for a quote and we’ll price your job on its own details.
Sending details for a quote
The more we know, the firmer the quote. Helpful details to send:
- Clear photographs of the problem areas
- Your programme or deadline
- What the building is and how it’s used
- The postcode of the building
Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.
For managing agents and facilities managers
Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
If you look after buildings for someone else, you need clear quotes and clear reporting. You get a fixed quote, an agreed scope and a walk round at the end, plus a 12-month guarantee.
What we’re called out for in Cotman's Ash
Sometimes the substrate is the problem: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
These are often picked up first by site or facilities staff:
- Weathered facade joints that have lost their grip
- Discoloured or dirty facade joints
- Leaks at window and door perimeters
- Patch repairs that keep failing
Historic houses such as Lullingstone Castle, 3.4 miles north-west of Cotman's Ash, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.
What your quote should include
- Their pre-qualification and accreditations
- What the guarantee covers, and for how long
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Mastic packages on Cotman's Ash sites
Cotman's Ash is about 19 miles from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, and main contractors there need mastic that keeps to the programme. Rainfall across the South East, Cotman's Ash 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 the external programme keeps a little slack.
New units and refits on sites such as Chaucer Business Park, 1.3 miles south of Cotman's Ash, need their panel and perimeter joints sealed to the specification. Projects at schools like Kemsing Primary School work to term dates, so mastic is programmed tightly.
