About our facade sealing in Beckenham
Facade joints are the line of defence between the weather and the building fabric. Once a perimeter seal fails, water tracks in around frames and panels. We remove failed sealant and install a new bead chosen for the joint and how far it moves. We work on coping and flashing joints, window and door perimeters and shopfront frames, and what we’re called in for most is new sealant peeling off old mastic and perimeter sealant that has split or peeled away. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: in Beckenham, that means joint design, primers and backing rod as standard.
Every London site, Beckenham included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Contractors’ notes for Beckenham
Beckenham has several hotels close by, all within 2 miles. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Every borough of Greater London is inside the ULEZ, and that applies to contractors’ vehicles on any job in Beckenham. Delivery slots and scarce storage shape how and when the mastic goes in.
Work at a hotel such as Bromley Court Hotel (to the north-east of Beckenham) tends to be programmed around bookings, mastic included. Further education sites such as Capel Manor College (to the west of Beckenham) are extended and refurbished from time to time, with mastic often programmed into the summer break. Hospital estates such as Sloane Hospital, 1 mile east of Beckenham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan.
Beckenham is about 7 miles south-east of London, in Greater London. Our applicators travel to Beckenham for work on facade joints. Our Greater London coverage takes in 764 places, from busy centres to rural villages. For work in that direction, see our London page (7 miles or so).

What the job involves on each surface
Render and coated surfaces
Where the joint will be painted over, a paintable hybrid or PU sealant may suit. We confirm the product with you before starting.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.
Doing it in-house
The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

Aftercare for building managers
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Insist on a full cut-out when joints are renewed
- Keep the sealant details on the building file
- Combine resealing with other works that need access
- Investigate damp beside windows promptly
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Coordinate facade sealing with other external works. Sharing the access keeps the cost down and limits disruption.
Beckenham: questions and answers
Can you work on a hospital site such as Sloane Hospital?
Yes. Healthcare sites are among the places we work. Each area is agreed with the ward or department and the estates team in advance.
Do you take on jobs in Beckenham where loading and access are tightly controlled?
Yes, we plan every London job around the building’s own access rules. Say when the building is occupied and when it’s quiet, and we’ll plan accordingly. We allow for the ULEZ, which covers every borough
When can the area be used after sealing?
Curing time varies by product, and we confirm it on the day.
Does the weather affect the work?
Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.
Do you have public liability insurance?
Yes. Our insurance certificate can be sent alongside the quote.
What site paperwork can you supply?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
Why it’s worth doing now in Beckenham
Each spell of rain drives water past a failed facade joint. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing early costs far less than repairing what the water reaches. Getting scaffold, permits or access booked in Beckenham takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote and we will explain how it’s made up.
