How the job changes by surface
Cladding panel joints
Panel joints on cladding and rainscreen systems take movement every day. We use a product rated for the movement and suited to the panel surface.
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use.
About our facade sealing in Coxheath
A good facade joint depends on design as much as product. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces. We work on coping and flashing joints, window and door perimeters and shopfront frames, and the usual reasons a site gets in touch are water coming in around window frames and failed sealant on precast panel joints. For commercial sealant work in Coxheath, you deal with one contact from quote to sign-off, whether it’s one building or several.
On a small site around Coxheath, the mastic is best done in the fewest visits we can manage. Let us know the key stages and we will time the work so nothing waits on us.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Contractors’ notes for Coxheath
Coxheath lies roughly 31 miles out from central London. Construction around the commuter belt mixes station-side flats with refurbished offices and units, so mastic packages have to keep pace with busy programmes. Coxheath is in the South East, one of the UK’s drier regions. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.
Extensions at sites like Maidstone Hospital (2.8 miles north of Coxheath) normally sit beside working departments, and the mastic follows strict access rules. School extensions, at buildings such as Coxheath Primary School, normally run to the summer holidays, mastic included. New units and refits on sites such as Tovil Green Business Park (to the north of Coxheath) need their panel and perimeter joints sealed to the specification.

- Damaged frames that need replacing

Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Coxheath: questions and answers
Could you schedule work at a campus like University for the Creative Arts - Maidstone for the vacation?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. We’re 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 Maidstone Hospital?
Yes, provided the work is planned with the site’s estates team. We follow the site’s permits, sign-in and infection-control procedures in every area.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
What’s the quickest route to a quote?
There are four steps: send details, get a quote, we seal, guaranteed. Step one needs little more than photographs and a postcode.
Do you install glazing systems?
No. We don’t install glazing systems, windows or glass. We seal the joints around them, including perimeters where frames meet the structure.
Do we need an asbestos check before resealing?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register. Suspect material is left alone until it has been tested.
Keeping the joints sound
Once the work is signed off, a little attention goes a long way:
- Don’t wait for a second leak before calling
- Keep pressure washers away from fresh sealant
- Keep the sealant details on the building file
- Check that rainwater leaves the facade the way it was designed to
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.
Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.
Leave it or put it right?
Open facade joints also let air and dirt through: occupants notice draughts and cold spots around windows. Resealing deals with the draught as well as the leak. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits.
