Facade sealing for commercial buildings in Kennington
Water ingress at window frames is a frequent reason facilities managers contact us. Very often the perimeter bead has cracked or lost its grip, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about gaps between rainscreen or cladding panels and weathered joints at frame-to-structure perimeters, on perimeter joints where frames meet the structure, coping and flashing joints and shopfront frames. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Kennington, preparation and product choice get the time they need.
Conversions around smaller places like Kennington often join new frames to old masonry or timber, which leaves joints between old walls and new frames that need a sealant able to take the movement.

What else we do in Kennington
Facade sealing in Kennington: the local picture
Kennington is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Kennington is about 48 miles from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.
New units and refits on sites such as Eurogate Business Park, 0.8 miles west of Kennington, need their panel and perimeter joints sealed to the specification. For a contractor working at a hospital such as The One Ashford Hospital (2 miles south-east of Kennington), perimeter and facade sealing is planned around patients and deliveries. Projects at schools like Kennington Church of England Academy work to term dates, so mastic is programmed tightly.
Kennington is about 2 miles north-east of Ashford, in Kent. Our applicators travel to Kennington for work on facade joints. Kennington is one of 931 places in Kent on our list for facade joints. We also cover London, some 48 miles away.

What the job involves on each surface
Coping and flashing joints
Sometimes the coping or flashing itself has failed. Where the issue isn’t the sealant, we say so.
Window and door perimeters
Perimeter joints move as frames expand and contract in the sun. The rod limits depth, leaving the bead able to flex without tearing.
Our process
We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Several jobs near Kennington can be grouped on one trip. Tell us your site hours and we will plan around them.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- 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.
Before we start on site
- Let building users know which areas are affected
- Send your site hours and access windows
- Agree which areas must stay open

Related advice
Keeping the joints sound
After handover, a little attention goes a long way:
- Record the product and colour used on each elevation
- Plan facade sealing alongside redecoration
- Keep sills, gutters and drainage paths clear
- Brief window cleaners about newly sealed joints
Keep gutters, sills and drainage paths clear. Good drainage keeps water moving off the facade.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it, and work stops until it’s tested if it’s suspected.
Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Providing access systems for the work
- Leaks from roofs, gutters or failed flashings rather than sealant joints
- Installing or repairing glazing systems
If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Common questions from Kennington clients
Can work at a site such as Ashford College fit around teaching?
Yes. Tell us the term dates, vacation periods and access windows, and we will plan the work around them. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like The One Ashford Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Do you seal facades in winter?
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, and we build that into the programme.
Can the sealant be colour-matched?
In many cases, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We will confirm the colours available for the specified product.
Do you take on multi-site work?
Yes. Multi-site work and planned programmes are a core part of the service, with each site phased to suit its occupants.
Do you guarantee your work?
Yes. It runs for twelve months and covers how we prepared and sealed the joints, but not damage, misuse or other trades’ work.
What affects the price in Kennington
To price the job, we consider:
- Induction, permit and paperwork requirements
- The product specified
- Access and working height
- The total length or number of joints
Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.
What to include in your enquiry
It doesn’t need to be a full survey. These details are enough to start:
- How the joints are reached, and at what height
- The asbestos register, for older buildings
- Any specification or named product
- What the building is and how it’s used
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or use the quote form.
