Facade sealing in Orpington, done properly
Facade joints are the line of defence between the weather and the building fabric. When a perimeter bead splits or peels, water finds its way behind frames and into the structure. We remove failed sealant and install a new bead chosen for the joint and how far it moves. Site teams most often ask us about failed sealant on precast panel joints and cold air coming in at window perimeters, across perimeter joints where frames meet the structure, window and door perimeters and stone and brick facade joints. A single leaking joint is often how a building in Orpington first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around Orpington, as across London, much of the work is refurbishing existing buildings as well as building new ones. Replacement windows, recladding and fit-outs leave perimeter and facade joints to seal, often next to people still using the building.
Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Our process
Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- We remove the old bead and check the edges are sound.
- Joints are cleaned, primed if required and fitted with backing rod.
- Facade-grade sealant goes in and is tooled to a tidy concave profile.
- Once signed off, the work carries our 12-month guarantee.
Preparing the site
- Warn occupants and staff about the work
- Tell us which areas need to stay in use
- For older buildings, check the asbestos register before work

Advice
General trades versus a specialist
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.
Looking after the joints
To get the most from the new sealant:
- Check the asbestos register before old mastic is disturbed
- Clear debris that holds water against joints
- Keep the sealant details on the building file
- Avoid harsh cleaners on facade sealant
Hold back any cleaning crew until the joints have had their stated cure time. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.
Planned resealing is cheaper than reacting to leaks. Inspect regularly and reseal sections as they start to fail instead of after the damage.

What else we do in Orpington
Questions we’re asked in Orpington
Do you take on work at healthcare sites like Orpington Hospital?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Do you cover business parks and estates near Orpington, such as Halo Business Park?
Yes, sites like Halo Business Park are within our area, along with the rest of Orpington. To start, just ring 01277 525 020 or email us with the unit, the joints involved and your access times.
Is old mastic on our building likely to contain asbestos?
For older buildings, yes, check before work starts. The dutyholder holds the asbestos register, so ask for it before we start. Suspect material is left alone until it has been tested.
What hours do you work?
Mention the site’s hours and access windows in your enquiry, and we will schedule the work to suit. Our office runs Monday to Friday, 8am until 5pm.
How many days will you need on site?
The duration is planned around your programme and the access we are given. We’ll give you an estimate of time on site when we quote.
Do you seal facades in winter?
Rain and frost can pause external sealing. We plan for weather and keep you updated throughout the job.
When is resealing likely to be due?
There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.
Leave it or put it right?
Patch repairs over old sealant tend to come back. A full cut-out and reseal costs more on the day but lasts much longer, so you aren’t paying for the same joint twice. 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. Putting it right early is less disruptive than dealing with the consequences.
Every site prices differently: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

Signs you need facade sealing in Orpington
The wrong product causes its share of trouble: an acetoxy cure can mark stone or corrode some metals, and interior products break down outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Things that usually lead to an enquiry:
- Water coming in around window frames
- Perimeter joints where frames meet the structure
- Gaps between rainscreen or cladding panels
- Air leaks through failed facade joints
For contractors refurbishing units at places like Halo Business Park, 0.6 miles north-east of Orpington, the mastic covers cladding panels, roller-door and window perimeters.
Questions to ask before you book
- How they handle RAMS and site documents
- How long is the guarantee, and what does it include?
- Their public liability cover
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
