Common problems we fix in Buchlyvie
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that cannot keep up eventually tears.
The most common problems we see are:
- Old mastic that has gone black or come away
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
In and around Buchlyvie, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

How we handle window mastic in Buchlyvie
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the line suits the frame instead of standing out. If you have old mastic that has gone black or come away and gaps where the sill meets the wall, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Frames and glazing around Buchlyvie
The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out. 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.
Homes close to North Church and Churchyard include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Buchlyvie: your questions answered
Is there a guarantee on window mastic in Buchlyvie?
All our work, in Buchlyvie and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Buchlyvie?
Yes, we do. We work across all of Scotland, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you do commercial work?
Yes. We work in offices, washrooms, hotels and other commercial premises. Working times can be discussed when we quote.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can landlords and businesses book you?
Yes. We work for householders, landlords, letting agents, businesses and hotels in Buchlyvie.
How long should I leave it?
Different products cure at different speeds, so follow the cure time we give you when we finish.
Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before work begins.
Can I paint over the new sealant?
Not generally, if it’s silicone. Tell us your decorating plans and we’ll pick a sealant to suit.
Different surfaces, different methods
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match suits the frame.
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
The process
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a place like Buchlyvie, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Plan for the work area to be out of bounds to pets and children
- Move anything stored near the joints

Why act early in Buchlyvie
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
What you pay reflects the work, not a rough estimate. That is why we ask about the job first and agree the price before starting.
Why book with us
- Neat joints and a tidy finish
- Anti-fungal sanitary silicone in wet areas
- Every job guaranteed for a year
- Domestic, commercial and hotel work

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep paint off silicone joints
- Make sure the drainage slots aren’t blocked
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What else we do in Buchlyvie
Work for landlords, hotels and businesses
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
