Cost factors for facade joints
A fixed quote reflects the actual work. It takes account of:
- Whether old sealant has to be cut out first
- How accessible the joints are
- Location, for remote and island sites
- Phasing around occupants
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote.
What to include in your enquiry
We can often quote from photos and a few details. It helps to include:
- The type of building and who uses it
- Your programme or deadline
- The postcode of the building
- Clear photographs of the problem areas
Photos, drawings or a schedule of the joints are often enough for a fixed quote. If the job needs a look first, we’ll arrange a site visit.
How we handle facade sealing in Kilnwood Vale
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. We work on coping and flashing joints, window and door perimeters and cladding panel joints, and what we are called in for most is discoloured or dirty facade joints and cold air coming in at window perimeters. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kilnwood Vale is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Kilnwood Vale is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Building owners and contractors get the same cover: a 12-month guarantee on our workmanship. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

Aftercare for building managers
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Investigate damp beside windows promptly
- Walk the elevations once or twice a year
- Ask about asbestos in pre-2000 mastic
- Brief window cleaners about newly sealed joints
Hold back any cleaning crew until the joints have had their stated cure time. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.
Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
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.
Questions about Kilnwood Vale
Can you work around term dates at a campus such as Crawley College?
Yes. Education sites usually want the work in vacations or in phases during term, and we plan to suit. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you work on a hospital site such as Crawley Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day, and flag anything to keep off until it has cured.
Do your applicators hold CSCS cards?
Yes. If you need card details for site access, let us know and we’ll send them with the quote.
Will you check whether the sealant is causing the leak?
Yes. We look at the perimeter sealant and tell you whether it has failed before quoting. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
What site paperwork can you supply?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we will confirm with the quote.
What do you charge?
There isn’t a price list, because every site is different. Send photographs or drawings and we’ll price it at a fixed figure.

Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager.

What we are called out for in Kilnwood Vale
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. With no backing, the sealant is restrained and rips when the facade moves.
Look out for the following:
- Perimeter joints where frames meet the structure
- Sealant pulling away from frames or panels
- Gaps between rainscreen or cladding panels
- Cold air coming in at window perimeters
For contractors at a school such as The Bewbush Academy, sealing has to be finished before term starts.
