Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.
After the work
Problems stay small when the joints are checked regularly. In particular:
- Brief window cleaners about newly sealed joints
- Never let anyone seal over old sealant
- Record the product and colour used on each elevation
- Ask about asbestos in pre-2000 mastic
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail, rather than waiting for a ceiling stain.
How we handle facade sealing in Crosspost
Every facade quote starts with how the joints will be reached. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site, and we will fit the work around it. If you have hard, chalky sealant that no longer flexes and cold air coming in at window perimeters, we can help, whatever the surface. A single leaking joint is often how a building in Crosspost first comes to us: we look at the rest while we’re there and tell you what we find.
Construction in and around smaller places such as Crosspost is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Honest limits
A proper diagnosis includes knowing what sealant can’t do. We’ll tell you if the real problem is any of the following:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Movement beyond what any sealant can handle
- Cracked or spalling substrates that need repair before sealing
If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think.

Quoting for work in Crosspost
To price the job, we consider:
- Site requirements such as inductions and permits
- Removal of failed or old sealant
- Location, for remote and island sites
- The product specified
The specified product makes a difference, and so does the preparation. Access, phasing and site requirements come into it too.
Details that help us quote
Good information means a firmer quote. When you get in touch, include:
- Drawings or a marked-up plan, if available
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Any specification or named product
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we will arrange a site visit if anything is unclear.

Building owners, agents and FMs in Crosspost
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Crosspost can form part of a wider programme across West Sussex.
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.
Why deal with it now?
Each spell of rain drives water past a failed facade joint. 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. Older rural buildings around Crosspost move with the seasons, and rigid or tired sealant can’t keep up. The right product, sized to the joint, copes much better.
The price depends on how many linear metres there are, what has to come out first and the access. Call for a fixed quote when you are ready.

- Constructionline member for supplier checks
- A fixed quote before work starts

Common questions from Crosspost clients
Is Crosspost off your patch?
No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work at a site such as Crosspot Industrial Estate, by Crosspost?
Yes. We cover Crosspost and the area around it, including industrial estates, business parks and retail parks such as Crosspot Industrial Estate. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is your workmanship covered by a guarantee?
Yes. Our workmanship is backed for 12 months.
Do your applicators hold CSCS cards?
Yes. We use CSCS-carded applicators, which many sites require.
Do you use silicone for external joints?
The product follows the joint’s movement, the surfaces and the specification. BS EN 15651 Parts 1 and 2 cover facade and glazing sealants, and specifications often name them and we follow the specified product.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Facade sealing in Crosspost: the local picture
The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so the external programme keeps a little slack. The area within 2 miles of Crosspost holds a number of hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
When a school such as Bolney CofE Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. On a healthcare site such as The Dene Hospital, which lies south-east of Crosspost, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. Older buildings in the area around Crosspost, such as Ockenden Manor (3.1 miles north-east of Crosspost), need care when sealed: the product has to suit soft or historic materials.
