About our window mastic in Ravenstruther
Around Ravenstruther we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We’re often asked to deal with rushed sealant from a window installation and cold air getting in at the frame edge, across timber windows & doors, aluminium frames and patio & French doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee.

For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
When to call us in Ravenstruther
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
Look out for any of the following:
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Mastic that has split away from the wall
Managing a site like Lanark Grammar School? Then the mastic around its windows and doors needs looking after like any other building’s.
What your quote should include
- Whether they’re fully insured
- Whether the sealant suits the joint
- How much experience the applicator has
- How long to leave it before use
Surface by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
A composite door generally sits in a plastic outer frame, and the joint around it is sealed like a window. The bead is colour-matched to the frame.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Paint up to the joint, not over it
- Ventilate rooms so frames don’t stay wet inside
- Keep paint and stain on wooden frames in good order
- Wash the frames with mild soapy water
Silicone cannot generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.

What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a place like Ravenstruther, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Keep pets and children clear of the area while we work
