Facade sealing in Charlton-on-Otmoor, done properly
External sealing depends on the weather more than most trades. The sealant needs a dry joint and temperatures inside the maker’s limits, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. Most enquiries involve air leaks through failed facade joints and weathered facade joints that have lost their grip, on perimeter joints where frames meet the structure, shopfront frames and coping and flashing joints. Facilities teams, main contractors and managing agents in Charlton-on-Otmoor tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.
Conversions of older rural buildings near smaller places such as Charlton-on-Otmoor bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is normally what’s needed.
The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we are clear about what is covered before work starts.

Site staff or a sealant specialist?
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
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.
How the job changes by surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. We use a sealant with the right movement capability, set over backing rod with primer where the product requires it.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end.
Common questions from Charlton-on-Otmoor clients
Is hospital work, at somewhere like Bicester Community Hospital, something you do?
Yes, hospitals are one of the sectors we cover. We follow the site’s permits, sign-in and infection-control procedures in every area.
Is Charlton-on-Otmoor too far out for you?
No. Places such as Charlton-on-Otmoor are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Can you find out why a window is leaking?
Yes. We check the sealant joints and report what we find before quoting. Where the cause seems to be elsewhere, we’d rather tell you than reseal pointlessly.
What’s the quickest route to a quote?
The quote form is the simplest route, though you can also ring 01277 525 020 or email us. Include photographs or drawings if you have them.
Can you work on upper floors?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions, and the quote will reflect it.
What will the job cost?
It depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote.
Can you work to our specification?
Yes. The specification and the manufacturer’s installation guidance are what we work to.
Looking after the joints
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Check the asbestos register before old mastic is disturbed
- Never let anyone seal over old sealant
- Avoid harsh cleaners on facade sealant
- Share access with other external trades
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading inside the building.
When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Work on the window or framing system itself
- Render or concrete edges that have broken away
- Damp caused by condensation inside the building
Not sure which it is? You can ring 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes.
