Facade sealing for Cold Ash sites
Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.
Should maintenance staff do it?
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.
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.
Facade sealing in Cold Ash
External sealing depends on the weather more than most trades. Joints have to be dry and the air and surface temperature within the product’s range. We plan for that and keep you updated. Most enquiries involve water coming in around window frames and sealant pulling away from frames or panels, across stone and brick facade joints, cladding panel joints and perimeter joints where frames meet the structure. Whoever orders the work in Cold Ash, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Conversions of older rural buildings near smaller places such as Cold Ash bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.
Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

When to call us in Cold Ash
Sometimes the substrate is the problem: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Clients typically get in touch after noticing something like this:
- Patch repairs that keep failing
- Damp patches beside frames after rain
- Sealant pulling away from frames or panels
- Failed seals around shopfront and entrance frames
Hotels like Regency Park Hotel (to the south of Cold Ash) rarely close for long, so refurbishment mastic is phased floor by floor.

Common questions from Cold Ash clients
Is a hospital such as West Berkshire Community Hospital somewhere you can work?
Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.
Will you take on work at estates like Red Shute Hill Industrial Estate, close to Cold Ash?
Yes, sites like Red Shute Hill Industrial Estate are within our area, along with the rest of Cold Ash. Photos and a short description are enough for a first look.
Should we check old sealant for asbestos?
In older non-domestic buildings, old sealant can contain asbestos. Check the asbestos register or survey before it is disturbed; if it’s suspected, work stops until it has been tested. Removal of asbestos isn’t something we do.
Is Cold Ash in your area?
Yes. Cold Ash falls within our area, and the simplest way to start is to speak to us on 01277 525 020 or use the quote form.
Do you guarantee your work?
Yes, for 12 months. If our installation fails in that time, we return and fix it.
Do you take on small jobs?
Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.
Does weather matter for sealant work?
For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
After the work
Cleaning and maintenance staff play a part too. Share these points with them:
- Add perimeter sealant to planned maintenance checks
- Check that rainwater leaves the facade the way it was designed to
- Brief window cleaners about newly sealed joints
- Combine resealing with other works that need access
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
Building facade joints into a maintenance cycle avoids emergency repairs. Inspect regularly and reseal sections as they start to fail instead of after the damage.

What else we do in Cold Ash
Mastic packages on Cold Ash sites
Cold Ash sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Central London is about 51 miles from Cold Ash. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme.
When a school such as Cold Ash St Mark's C.E. School is extended or refurbished, the mastic package is often squeezed into the holidays. Extensions at sites like West Berkshire Community Hospital, 1.8 miles to the south-west of Cold Ash, normally sit beside working departments, and the mastic follows strict access rules.

How a job runs
In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed before the next one starts. Jobs in and around smaller places like Cold Ash are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.
- We plan access and the order of elevations with the client.
- 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.
- We hand over with our 12-month workmanship guarantee.
What we need from you
- Arrange parking or a loading space

What the job involves on each surface
Precast concrete panels
Precast panel joints have to absorb thermal and structural movement. A sealant of the right movement class goes in over backing rod.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. They sit in the most exposed positions on the building.
