Facade sealing for Otford sites
Photos, a specification or a quick description of the joints is enough to start a fixed quote.
Facade sealing in Otford, done properly
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. Most enquiries involve staining on stone next to old sealant and weathered facade joints that have lost their grip, on window and door perimeters, cladding panel joints and perimeter joints where frames meet the structure. Most enquiries from Otford 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.
Conversions around smaller places like Otford often join new frames to old masonry or timber, and the sealant at those junctions has to cope with two materials that move differently.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

When to bring in a specialist
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Sites and facades in and around Otford
The area within 2 miles of Otford holds several hotels. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Otford is about 18 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, and main contractors there need mastic that keeps to the programme.
For a contractor working at a hospital such as Sevenoaks Hospital, 1.6 miles to the south of Otford, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Goya Business Park Sevenoaks (1.1 miles south of Otford) brings panel joints and frame perimeters into the programme.

After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Avoid harsh cleaners on facade sealant
- Check the asbestos register before old mastic is disturbed
- Report water ingress at frames as soon as it shows
- Insist on a full cut-out when joints are renewed
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
How a job runs
We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. If neighbouring businesses or buildings around Otford need work too, visits can be combined. Mention the building’s opening times and we will work within them.
- We look at the joints, the drawings and the access before pricing.
- 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.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
What we need from you
- Share the asbestos register for older buildings
- Move anything stored against the joints
- Point out parking and an unloading spot

What happens if it’s left?
If access is already up for other work, resealing at the same time makes sense. Combine it with planned external works and you only arrange access once, which is often the biggest saving. Sealant hardens, cracks and loses grip with age, UV and movement. Replacing it before it fails keeps water out.
The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

FAQs: Otford
Do you take on work at healthcare sites like Sevenoaks Hospital?
Yes, hospitals are one of the sectors we cover. Work is phased so departments keep running, under the site’s own rules.
Is Otford off your patch?
Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and we will price the work to it, flagging anything that needs clarifying.
Can you look at water coming in around a frame?
Yes. Photos help, and you can phone 01277 525 020 or send photos by email to arrange a visit. Failed perimeter sealant is a common cause, but not the only one, and we will tell you which.
How do you choose the sealant?
The specification comes first, if there is one. If there isn’t one, it comes down to the joint: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
Will you quote for a small job?
Single areas, one-off repairs and whole buildings are all quoted the same way: details, then a fixed price, then sealing, then a 12-month guarantee.

Do you need facade sealing in Otford?
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
These are often picked up first by site or facilities staff:
- Cladding panel joints that have opened up
- Weathered facade joints that have lost their grip
- Air leaks through failed facade joints
- Perimeter sealant that has split or peeled away
For a contractor at a hotel such as Donington Manor Hotel (1.5 miles south-west of Otford), the mastic often has to be finished before a reopening date.
What to look for in a quote
- How the joint faces will be prepared and primed
- The named product and why it was chosen
- Proof of insurance
- Whether their applicators hold CSCS cards
How the job changes by surface
Perimeter joints at frames and structure
The joint around a framed system, where it meets the structure, needs sealant. Our work is that perimeter joint rather than the system it surrounds.
Brick and stone facades
Stone can absorb plasticisers from the wrong sealant. We use a product suitable for the stone where the specification names one, with masked edges for a clean line.
