Facade sealing for commercial buildings in Barnehurst
Managing agents and owners in Barnehurst ask us to, we reseal perimeters across whole elevations or a handful of problem windows. The approach doesn’t change with the size: cut out, clean, back, prime where needed and seal. Each job carries our 12-month guarantee. Most enquiries involve cold air coming in at window perimeters and perimeter joints where frames meet the structure, across coping and flashing joints, window and door perimeters and perimeter joints where frames meet the structure. Most enquiries from Barnehurst start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
A great deal of London construction is refurbishment of occupied or part-occupied buildings, alongside new blocks. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building, so tidy, well-planned work matters.
Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

New build and refits around Barnehurst
Site traffic in Barnehurst falls within London’s ULEZ, like everywhere else in Greater London. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. Barnehurst has several hotels close by, all within 2 miles. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.
Work at a hotel such as Bexleyheath Marriott Hotel (0.9 miles south-west of Barnehurst) tends to be programmed around bookings, mastic included. Recladding or extending a unit at a site like Bourne Industrial Park (to the south of Barnehurst) brings panel joints and frame perimeters into the programme.

How the job changes by surface
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
Perimeter joints at frames and structure
These frame-to-structure joints take a lot of movement and weather. They are cut out, cleaned, backed and resealed.
What happens if it’s left?
A few metres of new sealant compare well with replacing ceilings, linings or damaged stock. Leaks travel along the structure, often turning up far from the joint. In a London building, a failed joint rarely affects only one party: water travels through shared structures, and a small leak becomes a dispute between occupiers. Dealing with it early is simpler for everyone.
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

When something else is needed
Being straight saves everyone time. New sealant won’t cure:
- Joints too narrow for the movement they take, which need redesign
- Arranging specialist high-level access, which is planned with the client
- Cracked or spalling substrates that need repair before sealing
If in doubt, speak to us on 01277 525 020 or send photos by email and we will say what we think.

When to call us in Barnehurst
Sun, rain and temperature swings wear facade sealant down over the years. UV and weather harden the sealant until it can’t stretch with the building.
Look out for the following:
- Weathered facade joints that have lost their grip
- Damp patches beside frames after rain
- Cold air coming in at window perimeters
- Staining on stone next to old sealant
For contractors on a campus like University of Greenwich Avery Hill Campus, 4 miles to the west of Barnehurst, facade and perimeter sealing has to fit around students and term dates.
Before you book anyone
- Is the sealant right for the movement and the substrate?
- Do they follow the manufacturer’s priming guidance?
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
FAQs: Barnehurst
Will you take on work at estates like Bourne Industrial Park, close to Barnehurst?
Yes. Our area takes in Barnehurst and its surroundings, with estates and business parks such as Bourne Industrial Park included. Photos and a short description are enough for a first look.
Could you schedule work at a campus like University of Greenwich Avery Hill Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Can you find out why a window is leaking?
Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
Can you send site paperwork?
Each site asks for different documents, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.

What else we do in Barnehurst
Looking after the joints
Regular inspection catches problems early. In particular:
- Check the asbestos register before old mastic is disturbed
- Share access with other external trades
- Avoid patch repairs on failed facade joints
- Add perimeter sealant to planned maintenance checks
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
On site: what to expect
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Planning a London job such as one in Barnehurst starts with access: booked loading, goods lifts, the building’s permit system and a spot to keep materials. Give us the hours we can be on site and we will schedule to suit.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- 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
- Let building users know which areas are affected
- Tell us your opening times and when work is allowed
