Photos, a specification or a quick description of the joints is enough to start a fixed quote.
General trades versus a specialist
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
About our facade sealing in Hamsey Green
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, while rod fixes the depth and stops the bead sticking to the rear with the ratio the sealant maker recommends, often around 2:1. If you’re dealing with weathered facade joints that have lost their grip and unsightly perimeter sealant on a visible elevation, we can help, on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters alike. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Hamsey Green is the same: the right product in a properly prepared joint.
Construction in a London area such as Hamsey Green means working on constrained sites: small compounds, delivery slots and shared hoists and scaffold. Mastic is normally one of the last trades on each elevation or floor, so we keep to the programme and the order of trades the site sets.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

On site: what to expect
Site rules come first: signing in, inductions and any permit to work. With the paperwork done, we take the joints in the sequence agreed with you, and each area is checked before we leave it. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.
Preparing the site
- Share the asbestos register for older buildings
- Explain the parking and delivery arrangements
- Flag any permit to work we’ll need

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

What we are called out for in Hamsey Green
Most facade joints fail through age and weathering. UV and weather harden the sealant until it can’t stretch with the building.
If one of these sounds familiar, it’s time for a closer look:
- New sealant peeling off old mastic
- Cladding panel joints that have opened up
- Hard, chalky sealant that no longer flexes
- Weathered joints at frame-to-structure perimeters
Work at a hotel such as Selsdon Park Hotel (1.4 miles north of Hamsey Green) tends to be programmed around bookings, mastic included.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint
- Will failed sealant be removed rather than covered?
- Their pre-qualification and accreditations
- Their plan for phasing and protecting the area
Questions we’re asked in Hamsey Green
Do you work in London buildings with loading restrictions?
Yes, we plan every London job around the building’s own access rules. The building manager’s rules go straight into our method. All of Greater London is inside the ULEZ, and our planning allows for it
Would you work within a site like Purley War Memorial Hospital?
Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.
Are your applicators CSCS-carded?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Can you work in cold or wet weather?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Cold, damp mornings can delay a start.
How do we ask for a quote?
You can use the quote form on this site; alternatively, call 01277 525 020 or email drawings and photos. Photos, drawings or a joint schedule help us quote quickly.
Can the sealant be colour-matched?
That depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
How many days will you need on site?
The duration is planned around your programme and the access we’re given. You will have an expected duration with the quote.
What the job involves on each surface
Precast concrete panels
Precast arrises sometimes crumble or carry old residue. We clean back to sound material and flag edges that need repair before sealing.
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and areas needing repair are flagged.
Facade sealing in Hamsey Green: the local picture
As part of Greater London, Hamsey Green is inside the ULEZ, which applies to every van on site. Deliveries are booked and storage is tight, so mastic materials come in as needed. There are several hotels within about 2 miles of Hamsey Green. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included.
School extensions, at buildings such as Hamsey Green Primary, normally run to the summer holidays, mastic included. New wings at hospitals like Purley War Memorial Hospital (to the north-west of Hamsey Green) bring long runs of window and panel joints to seal.
Hamsey Green is about 1 mile north of Warlingham, in Greater London. Commercial clients in Hamsey Green can call on us for facade joints, as part of our coverage of Greater London. Hamsey Green is one of 764 places in Greater London on our list. London is covered too, some 13 miles away.
Anyone looking for facade sealing in CR6 and CR2 gets the same process as the rest of our area: details, then a fixed price, then sealing and a 12-month guarantee. Among the streets we cover are Clyde Avenue, Crewe's Lane and Princes Avenue, and sites on any of them can send details for a fixed quote. We also cover Warlingham (1 mile south), Whyteleafe (1 mile south-west), Chelsham (1 mile east), Sanderstead (1 mile north-west) and Farleigh (1 mile east) for facade joints. Bigger towns within reach include London (13 miles north), City of Westminster (14 miles north), Marylebone (14 miles north), Kensington (14 miles north-west), St Pancras (15 miles north) and Shoreditch (14 miles north).
Around Hamsey Green
We work on buildings around The White Lion Public House, Warlingham School and Blanchman's Farm and the streets around them. The nearest railway station is Upper Warlingham station, roughly 1 mile south-west. A little further out are East Surrey Museum (2.6 miles south) and Warlingham Park Hospital (1.4 miles east). Green spaces nearby include South London Downs National Nature Reserve and Nore Hill.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Render or concrete edges that have broken away
- Work on the window or framing system itself
- Joints too narrow for the movement they take, which need redesign
If in doubt, call the office on 01277 525 020 or email the details over and we will say what we think.
What we seal
- Perimeter joints where frames meet the structure
