We are often asked to deal with leaking joints at the ends of sills and gaps left after new windows were fitted, across uPVC windows, composite doors and window sills.
Outdoor sealant needs a dry surface, so window work around Croy is planned around the weather. Tell us about access to all the windows and doors, upstairs included.

Where do you work from?
We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.
Do you guarantee window mastic?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we’re using and why.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.

How the job changes by surface
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Do you need window mastic in Croy?
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
The problems people usually mention when they call include:
- Untidy mastic left by window fitters
- Cracked or shrunken mastic around the frame
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
Managing a site like Our Lady's High? Then its window and door frames need their mastic kept sound, just like a home’s.
What to look for in a quote
- What insurance they hold
- What the quote includes, VAT included or not
- How the colour is chosen
- What preparation is included
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why act early in Croy
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Windows and doors in Croy
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Rented homes near Croy station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
