Facade sealing in Perry Vale
We don’t install glazing systems or replace glass. What we seal are the joints around them: perimeter joints where frames meet the structure, panel joints and window perimeters with products suited to facade or glazing perimeter joints. Most enquiries involve draughts around frames and panels and staining on stone next to old sealant, on coping and flashing joints, shopfront frames and perimeter joints where frames meet the structure. Whether you call it commercial sealant work, mastic application or joint sealing, in Perry Vale it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. Mastic is typically one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Every job is signed off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

Why act early in Perry Vale
The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Acting at the first sign of splitting keeps the fix simple. Failed sealant in a building in Perry Vale can quickly affect neighbours, tenants or the floor below: water travels through shared structures, and a small leak becomes a dispute between occupiers. Putting it right early is less disruptive than dealing with the consequences.
No two sites price the same: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Why appoint us
- Clear, fixed quotes
- 12-month guarantee on workmanship
- Colour options checked against the specified product

Contractors’ notes for Perry Vale
Site traffic in Perry Vale falls within London’s ULEZ, like everywhere else in Greater London. Delivery slots and scarce storage shape how and when the mastic goes in. A number of hotels sit less than 2 miles from Perry Vale. Hotel extensions and refits typically have to fit around bookings, so mastic dates are tight.
Recladding or extending a unit at a site like Clyde Vale Industrial Estate, 0.5 miles west of Perry Vale, brings panel joints and frame perimeters into the programme. University estates such as King's College London, 3.2 miles north-west of Perry Vale, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

What else we do in Perry Vale
Different surfaces, different methods
Brick and stone facades
On masonry, the sealant has to suit a porous, textured surface. Neutral-cure products are used because acetoxy types can mark some stone.
Render and coated surfaces
Sealant can only hold as well as the render or paint beneath it. Loose coatings are cleaned back first.
Common problems we fix in Perry Vale
A frequent fault is a bead stuck to the joint’s rear face as well as its sides. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Most enquiries start with one or more of the following:
- Cladding panel joints that have opened up
- Draughts around frames and panels
- Water coming in around window frames
- Discoloured or dirty facade joints
Hotels like Astra Palace Hotel (1.4 miles south-west of Perry Vale) rarely close for long, so refurbishment mastic is phased floor by floor.

Perry Vale: questions and answers
Can you work around term dates at a campus such as King's College London?
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.
Is hospital work, at somewhere like University Hospital Lewisham, something you do?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Can the sealant be colour-matched?
Often, yes. Many products come in a range of standard colours, and matching to RAL references or surrounding finishes is often possible. We confirm what’s available for the specified product when we quote.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email a schedule or drawings. Photos, drawings or a joint schedule help us quote quickly.
How is access to upper-level joints handled?
We agree access with the client at the start. Tell us about access: existing scaffold, what you’re arranging and any site restrictions, and we’ll price the work around it.
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.
Is the work guaranteed?
Yes, for 12 months. If a joint fails because of how we installed it, we come back and put it right.
General trades versus a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.
Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
On site: what to expect
Diagnose, treat, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then the work is carried out to the specified product and detail, and we finish with a walk round so the work can be signed off. For a job in Perry Vale, access comes first. Give us the hours we can be on site and we’ll schedule to suit.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- For older buildings, check the asbestos register before work
- Point out parking and an unloading spot
- Agree which areas must stay open
