Signs you need facade sealing in North Chailey
Cohesive failure, a split through the middle of the bead, points to an over-stretched joint. Too thin a bead, too narrow a joint or a product with the wrong movement class are common reasons.
Clients usually get in touch after noticing one or more of the following:
- Air leaks through failed facade joints
- Gaps between rainscreen or cladding panels
- New sealant peeling off old mastic
- Damp patches beside frames after rain
When a school such as Chailey Heritage School is extended or refurbished, the mastic package is often squeezed into the holidays.
Questions to ask before you book
- How long is the guarantee, and what does it include?
- Which product they’ll use, and why it suits the joint
- Proof of insurance
- Whether old or failed sealant will be cut out, not overlaid
Facade sealing for commercial buildings in North Chailey
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause. We’ll tell you if we think the leak is coming from somewhere sealant won’t fix. We work on shopfront frames, cladding panel joints and coping and flashing joints, and the usual reasons a site gets in touch are leaks at window and door perimeters and failed sealant on precast panel joints. For commercial sealant work in North Chailey, you deal with one contact from quote to sign-off, whether it’s one building or several.
Construction in and around smaller places such as North Chailey 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.
Every job we finish is backed by a 12-month workmanship guarantee, in North Chailey as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

What the job involves on each surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. The sealant has to match the movement and the panel finish.

Maintenance after handover
Sealant joints are maintenance items, and how long they last depends on how they’re treated. Our advice:
- Check that rainwater leaves the facade the way it was designed to
- Report water ingress at frames as soon as it shows
- Record the product and colour used on each elevation
- Never let anyone seal over old sealant
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.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down.

Facade sealing in North Chailey: the local picture
At about 37 miles from central London, North Chailey 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. North Chailey 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.
On a healthcare site such as Princess Royal Hospital, 3.4 miles west of North Chailey, new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. On a campus such as University of Sussex, 1.3 miles south-west of North Chailey, new teaching buildings and residences are normally built and refurbished around the academic year.
North Chailey is about 4 miles south-east of Haywards Heath, in East Sussex. Anywhere in BN8, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

North Chailey: questions and answers
Do you take on work at healthcare sites like Princess Royal Hospital?
Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Can you work around term dates at a campus such as University of Sussex?
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.
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, and we build that into the programme.
When can you be on site?
We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
How long do sealant joints last?
Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.
Is it okay to overlay old mastic?
No. New sealant won’t hold on old sealant, so the old bead is cut away and the joint cleaned back to sound material. Nothing else gives a bond that lasts.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
What sealant work can’t fix
Sealant solves a lot, but not everything, and we’re upfront when that’s the case. It won’t fix:
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Providing access systems for the work
- Movement beyond what any sealant can handle
If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.
