Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
What the job involves on each surface
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex as the frame moves.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish.
Facade sealing in Charlton, done properly
Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. The enquiries we see most involve discoloured or dirty facade joints and cladding panel joints that have opened up, on stone and brick facade joints, perimeter joints where frames meet the structure and cladding panel joints. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Charlton, preparation and product choice get the time they need.
Construction in and around smaller places such as Charlton 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.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Aftercare for building managers
After handover, a little attention goes a long way:
- Avoid harsh cleaners on facade sealant
- Note when each elevation was last resealed
- Check that rainwater leaves the facade the way it was designed to
- Never let anyone seal over old sealant
Anything drilled through a facade joint breaks the seal. Ask the installer to reseal it properly with a compatible product.
Building facade joints into a maintenance cycle avoids emergency repairs. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

Do you need facade sealing in Charlton?
The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Most enquiries start with one or more of the following:
- Weathered joints at frame-to-structure perimeters
- Failed sealant on precast panel joints
- Sealant pulling away from frames or panels
- Unsightly perimeter sealant on a visible elevation
Extensions at sites like Andover War Memorial Hospital (to the south-east of Charlton) normally sit beside working departments, and the mastic follows strict access rules.

Facade sealing in Charlton: the local picture
Rainfall across the South East, Charlton included, is lower than in many parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, which is why external dates are agreed with the site manager. Charlton has a number of hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included.
Projects at schools like Harrow Way Community School work to term dates, so mastic is programmed tightly. For a contractor at a hotel such as The Globe Hotel, 1.4 miles to the south-east of Charlton, the mastic often has to be finished before a reopening date.

Your questions answered
Is Mylen Road Business Park, near Charlton, within your area?
Yes. Our area takes in Charlton and its surroundings, with estates and business parks such as Mylen Road Business Park included. A few photos and the unit address let us price the work.
Do you take on work at healthcare sites like Andover War Memorial Hospital?
Yes. We work in healthcare settings as well as offices and schools. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Do you provide access for facade work?
We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions.
Do you work to architects’ specifications?
Yes. We follow the specification, along with the manufacturer’s installation guidance.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can you work in cold or wet weather?
Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start, and we build that into the programme.
Can you handle several sites?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
