What we can’t put right
Honesty saves time and money. New sealant won’t cure:
- Damp caused by condensation inside the building
- Joints whose design needs changing by the specifier
- Work on the window or framing system itself

Facade sealing in Elephant and Castle, done properly
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, while rod fixes the depth and stops the bead sticking to the rear. Site teams most often ask us about perimeter sealant that has split or peeled away and weathered joints at frame-to-structure perimeters, across perimeter joints where frames meet the structure, coping and flashing joints and cladding panel joints. Whether you call it commercial sealant work, mastic application or joint sealing, in Elephant and Castle it comes down to the same thing: the right product in a properly prepared joint.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. New frames, overcladding and fit-outs all end in perimeter and facade joints, frequently with occupants close by, so tidy, well-planned work matters.
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.

General trades versus a specialist
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
What sets the cost
To price the job, we consider:
- Removal of failed or old sealant
- Joint width, depth and condition
- Any access equipment needed
- Which sealant the job calls for
The product called for affects the cost, and so does the preparation. Access, phasing and site requirements come into it too.
What we need to price the job
A good diagnosis starts with the right details. Let us know:
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- Approximate linear metres or a joint schedule
- Anything awkward about access or site hours

Mastic packages on Elephant and Castle sites
Plenty of hotels sit less than 2 miles from Elephant and Castle. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. As part of Greater London, Elephant and Castle is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for.
For contractors refurbishing units at places like Grand Vitesse Industrial Estate, which lies north of Elephant and Castle, the mastic covers cladding panels, roller-door and window perimeters. Projects at colleges like Morley College London, less than half a mile north-west of Elephant and Castle, tend to run to term dates, so the mastic is planned tightly.
Elephant and Castle is about 1 mile south-west of London, in Greater London. Businesses, contractors and managing agents in Elephant and Castle use us for work on facade joints. Elephant and Castle is one of 764 places we cover in Greater London for facade joints.

Why deal with it now?
Every shower drives water through a split perimeter bead. Behind the frame, that can mean damp plaster, stained ceilings, corroded fixings and damaged insulation. Resealing now costs less than repairing interiors later. Getting scaffold, permits or access booked in Elephant and Castle takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote.

Signs you need facade sealing in Elephant and Castle
Adhesive failure, where the sealant peels away from one face, usually comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond, and the joint opens with the first real movement.
Site and facilities staff are often the first to spot these:
- Air leaks through failed facade joints
- Facade joints cracked through the middle
- Hard, chalky sealant that no longer flexes
- Failed seals around shopfront and entrance frames
For a contractor working at a hospital such as Evelina London Children's Hospital, which lies west of Elephant and Castle, perimeter and facade sealing is planned around patients and deliveries.

- The terms of the workmanship guarantee
- Which product they’ll use, and why it suits the joint
- Whether primer will be used where the manufacturer specifies it
FAQs: Elephant and Castle
Is a hospital such as Evelina London Children's Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Can you cope with the access rules in a London building?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Send the building rules and access times with your enquiry. All of Greater London is inside the ULEZ, and our planning allows for it
Is Elephant and Castle in your area?
Yes. Sites across Elephant and Castle are covered, with one number for every area we cover.
Can the building stay open while you work?
Typically, yes. We phase the work so most of the building stays in use.
Is old mastic on our building likely to contain asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. We don’t remove asbestos-containing materials.
Which sealant will you use?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
On site: what to expect
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Most London premises stay occupied while we’re on site, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- We walk the finished joints with you before handing over.
Before we start on site
- Tell us your opening times and when work is allowed
- Confirm the product named in the specification
- Let building users know which areas are affected
