How we handle facade sealing in Sanderstead
Managing agents and owners in Sanderstead ask us to, we reseal perimeters across whole elevations or a handful of problem windows. Either way, the method is the same: cut out, clean, back, prime where needed and seal. A 12-month guarantee applies to our workmanship. We work on stone and brick facade joints, cladding panel joints and shopfront frames, and what we are called in for most is perimeter joints where frames meet the structure and cladding panel joints that have opened up. Facilities teams, main contractors and managing agents in Sanderstead tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
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.
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.

Why act early in Sanderstead
Leaving failed perimeter sealant also makes the eventual job bigger: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

What sealant work can’t fix
A few problems need another trade or a different fix, and we say so rather than covering them up:
- Providing access systems for the work
- Movement beyond what any sealant can handle
- Installing or repairing glazing systems
If in doubt, give us a call on 01277 525 020 or email us and we’ll say what we think.

On site: what to expect
Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. 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.
- Photos, drawings or a visit tell us about the joints and the access.
- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full.
- Primer is applied where the maker specifies it.
- Rod goes in to fix the depth, then the joint is sealed and tooled.
- We go over the completed work with you before leaving.
Getting the site ready
- Tell staff and tenants when we’ll be in
- Make sure the joints can be reached
- Point out any areas we must not close

Advice
Your questions answered
Do you work in London buildings with loading restrictions?
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. The ULEZ covers the whole of Greater London, which we allow for
Can work at a site such as Purley Language College fit around teaching?
Yes. We plan campus work around teaching, exams and residence turnarounds. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Can you follow the specification on our project?
Yes. The specification and the manufacturer’s installation guidance are what we work to, and we raise anything unclear before work begins.
Is colour matching possible?
It depends on the product specified. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do you take on multi-site work?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
When to call us in Sanderstead
When sealant lets go of a frame or panel, the cause is often the preparation. Dust, old sealant residue, damp or a missing primer stop it bonding properly.
Clients typically get in touch after noticing something like this:
- Damp patches beside frames after rain
- Previous reseals run over old sealant
- Old perimeter mastic that has dried out
- Sealant pulling away from frames or panels
On a healthcare site such as Purley War Memorial Hospital (1.5 miles west of Sanderstead), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
Comparing quotes
- What site paperwork they can supply
- The named product and why it was chosen
- Whether old or failed sealant will be cut out, not overlaid
- Can the work be phased to keep areas open?
General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Redoing a failed joint typically costs more than getting it right at the outset, 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.
How the job changes by surface
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.
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, as the specification sets out.
New build and refits around Sanderstead
Site traffic in Sanderstead falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. There are a number of hotels within about 2 miles of Sanderstead. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Further education sites such as Purley Language College, 1.6 miles to the west of Sanderstead, are extended and refurbished from time to time, with mastic often programmed into the summer break. Hotel extensions and refits, at places such as Selsdon Park Hotel, which lies east of Sanderstead, typically run between busy periods, so the sealing is squeezed into short windows.
