Facade sealing in Cheam, done properly
A good facade joint depends on design as much as product. 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. If you have new sealant peeling off old mastic and weathered joints at frame-to-structure perimeters, we can help, whatever the surface. A single leaking joint is often how a building in Cheam first comes to us: we look at the rest while we’re there and tell you what we find.
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 is for workmanship rather than 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.

Questions about Cheam
Can you work in a London building with booked loading and goods-lift slots?
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 will plan accordingly. We allow for the ULEZ, which covers every borough
Will you plan work around the academic year at somewhere like University for the Creative Arts - Epsom?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can the building stay open while you work?
Normally, yes. We phase the work so most of the building stays in use.
Is your workmanship covered by a guarantee?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
Do you provide access for facade work?
We agree access with the client at the start. Let us know what access is in place or planned.
Will you just go over the old 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.
Can you handle several sites?
Yes. We take on portfolio and planned maintenance work, planned site by site to suit how each building is used.

Should maintenance staff do it?
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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
Owners, agents and contractors
Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.
As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.
What we’re called out for in Cheam
Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.
Any of the following is a good reason to get the joints checked over:
- Perimeter sealant that has split or peeled away
- Previous reseals run over old sealant
- Cladding panel joints that have opened up
- Discoloured or dirty facade joints
Units on estates such as Kimpton Industrial Park, 2 miles north of Cheam, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.
What your quote should include
- Whether their applicators hold CSCS cards
- Their pre-qualification and accreditations
- Their public liability cover
- Will failed sealant be removed rather than covered?
When something else is needed
Before quoting, we check that sealant is the right answer. It won’t put right:
- Joints too narrow for the movement they take, which need redesign
- Render or concrete edges that have broken away
- Work on the window or framing system itself
If in doubt, phone 01277 525 020 or send photos by email and we will say what we think before you book.
What we seal
- Shopfront frames
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Stone and brick facade joints
- Cladding panel joints
- Window and door perimeters
Diagnose, treat, sign off
Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. In Cheam, most buildings stay in use during the work, so we agree zones and timings with the building or facilities manager. Areas are handed back as each section is finished.
- We plan access and the order of elevations with the client.
- We only seal when joints are dry and within the product’s temperature range.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Make sure the joints can be reached
- Explain the parking and delivery arrangements
- For older buildings, check the asbestos register before work
Getting a fixed quote
If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photos and a description will do.

Keeping the joints sound
After handover, a little attention goes a long way:
- Insist on a full cut-out when joints are renewed
- Check the asbestos register before old mastic is disturbed
- Report water ingress at frames as soon as it shows
- Check that rainwater leaves the facade the way it was designed to
After heavy weather, check vulnerable elevations for signs of water inside. An early report normally means a small reseal rather than a bigger repair.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.
Facade sealing in Cheam: the local picture
Site traffic in Cheam falls within London’s ULEZ, like everywhere else in Greater London. Deliveries are booked and storage is tight, so mastic materials come in as needed. The area within 2 miles of Cheam holds a number of hotels. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
On a campus such as University for the Creative Arts - Epsom (2.6 miles south-west of Cheam), new teaching buildings and residences are typically built and refurbished around the academic year. Further education sites such as Sutton College of Learning for Adults, 1.2 miles to the north-east of Cheam, are extended and refurbished from time to time, with mastic often programmed into the summer break.
Cheam is about 1 mile south-west of Sutton, in Greater London. Anywhere in SM2, the process is the same: details in, fixed quote out, then sealing and a 12-month guarantee. Across Greater London, 764 places are covered, Cheam among them. We also cover London, around 12 miles from Cheam.
