Construction mastic in Kenley
Mastic is often where a new building first shows its quality to the client. A smeared bead round a window or a gap behind a worktop ends up on the snag list and clearing them late eats into the handover window. Our aim is joints that pass at the first inspection, area by area through the programme. We work on window and door perimeters, cladding and panel joints and floor and skirting junctions, and what we’re called in for most is new external sealant already peeling away and perimeter gaps outside the sealant’s range. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Kenley is the same: 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 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.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Send the building rules and access times with your enquiry.

New build and refits around Kenley
A number of hotels sit less than 2 miles from Kenley. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight. The ULEZ covers the whole of Greater London, Kenley included, so site vehicles need to meet its standards or pay the daily charge. Add booked deliveries and tight storage, and the mastic package needs planning with the site team.
Units on estates such as Ullswater Industrial Estate (to the west of Kenley) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. Further education sites such as Purley Language College (to the north-west of Kenley) are extended and refurbished from time to time, with mastic often programmed into the summer break.
Kenley is about 1 mile south-east of Purley, in Greater London. Businesses, contractors and managing agents in Kenley can call on us for mastic packages. 764 places across Greater London fall within our area, Kenley among them. London is covered too, around 12 miles from Kenley.

When it isn’t the sealant
Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:
- Specifying the product where the designer hasn’t
- Rework caused by others damaging completed areas
- Frame gaps too wide for sealant, which the installer needs to correct
If in doubt, call the office on 01277 525 020 or send details through our quote form and we will say what we think.

Do you need construction mastic in Kenley?
Frames installed with uneven gaps make perimeter sealing harder. Every product has limits on how wide a joint it can bridge and gaps beyond it need packing or adjusting by the frame installer. Better to raise it at the start than seal a joint that’s bound to fail.
Most enquiries start with one or more of the following:
- Early adhesion failures on new external joints
- Sealant knocked or painted over by other trades
- Old sealant on a refurbishment that needs stripping before new work
- Frame gaps too wide for sealant alone
With historic properties like Addington Palace, 3.3 miles north-east of Kenley, in the area, refurbishment work often meets old masonry that needs compatible sealants.
What your quote should include
- How they handle RAMS and site documents
- How joint depth will be controlled
- What level of public liability insurance do they hold?
- Their pre-qualification and accreditations
What happens if it’s left?
A quick bead over a damaged joint can get an area past inspection. New sealant laid on old or dirty sealant has nothing to bond to, and the defect comes back after handover. Damaged joints are removed and resealed from clean faces. Repeat call-outs disrupt occupied London buildings, so cutting the old sealant out fully and doing it right once is the better route.

General trades versus a specialist
Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Common questions from Kenley clients
Can work at a site such as Purley Language College fit around teaching?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you work on a hospital site such as Purley War Memorial Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.
Can you work to our specification?
We use the product the specification names. If we think an alternative would suit better, we put it to you first.
Can you seal external joints in wet or cold weather?
Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure so it’s better to wait.
How do you deal with asbestos in old sealant?
Asbestos is possible in some older mastics, particularly in buildings from before 2000. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. Removing asbestos is a job for asbestos specialists, not us.
How do we ask for a quote?
