About our facade sealing in Dane Hill
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. Most enquiries involve hard, chalky sealant that no longer flexes and failed sealant on precast panel joints, on perimeter joints where frames meet the structure, stone and brick facade joints and coping and flashing joints. A specialist sealant contractor works differently from a general builder: on jobs in Dane Hill, preparation and product choice get the time they need.
Around smaller places like Dane Hill, building work usually means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.
Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Surface by surface
Coping and flashing joints
Not every coping or flashing leak is a sealant problem. Where the issue isn’t the sealant, we say so.
Window and door perimeters
Window and door perimeters make up most facade sealing work. A low-modulus, neutral-cure product suits most frame-to-wall joints, tooled to shed water.
Doing it in-house
Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong typically costs more in the end than doing them right.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Why deal with it now?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts. One visit to deal with every failing joint makes more sense than several trips to a place like Dane Hill, rather than one at a time. Send photos of each area and we will quote for the lot.
The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Keeping the joints sound
After handover, a little attention goes a long way:
- Inspect facade joints on a regular cycle
- Insist on a full cut-out when joints are renewed
- Note when each elevation was last resealed
- Ask about asbestos in pre-2000 mastic
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration.
Tie resealing in with redecoration, cladding repairs or other access. One set-up for several trades saves money and cuts time on site.

Sites and facades in and around Dane Hill
There are several hotels within about 2 miles of Dane Hill. When hotels extend or refit, the work is normally squeezed between peak periods, mastic included. Dane Hill sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so we time external mastic for dry faces and agree it with the site team.
Hotel extensions and refits, at places such as Unicorn Hotel, 1.5 miles to the north of Dane Hill, typically run between busy periods, so the sealing is squeezed into short windows.

Questions about Dane Hill
Can you work to our programme on a site in or near Dane Hill?
Yes, we work to the programme and the sequence the site sets. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Is Dane Hill too far out for you?
Not at all. Dane Hill is within our area. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.
Do your applicators hold CSCS cards?
Yes. Our applicators hold CSCS cards, as many construction sites ask for.
Do you provide access for facade work?
That comes down to the access arranged for the job. Share what access exists or is planned when you send details, and we will plan the work with you.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
How much does the work cost?
We don’t publish prices, as every site differs. With photos or drawings, we can give you a fixed quote.
Is it fine to apply new sealant on top of old?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
Signs you need facade sealing in Dane Hill
New sealant run over old sealant rarely holds. Fresh silicone won’t stick to cured silicone.
If one of these sounds familiar, it’s time for a closer look:
- Gaps between rainscreen or cladding panels
- Weathered joints at frame-to-structure perimeters
- Water coming in around window frames
- New sealant peeling off old mastic
Units on estates such as Hatch End Old Industrial Estate, 1.8 miles south of Dane Hill, tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal.

- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Both faces are cleaned and, where the product needs it, primed.
