Window mastic for homes and businesses in Banbhaidh
Most frames have an outside joint and an inside one. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you’re dealing with whistling draughts around closed windows and hard, cracked sealant around windows, we can help.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
There’s a 12-month guarantee on every job.

What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- Any working-time requirements on site
- The number and length of the joints
- Whether there’s mould to deal with
- Whether the work is at height
The cost depends on how much there is to do, how hard the old material is to remove and access to the work. We give a clear quote before work begins.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Where the property is
- Photos by email, if that’s easy
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Getting a quote is simple: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we will come back to you with a quote.
What happens if it’s left?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone aren’t designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

What we’re called out for in Banbhaidh
Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Keep an eye out for any of the following:
- Mastic that’s falling out in pieces
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
- Draughts coming in around windows and doors
In and around Banbhaidh, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.
What to look for in a quote
- Which colour the sealant will be
- How the surfaces are prepared before sealing
- What happens if the job turns out different
- Whether all the old sealant comes out first
Landlords, agents and businesses in Banbhaidh
Letting agents often deal with us directly. Tell us the address, the job and how access works.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, carry out the job and tidy away. Most jobs take a few hours for a handful of frames, longer for a whole house. For a place like Banbhaidh, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
How to prepare
- Mention any tricky access
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
Getting a quote
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.

Windows and doors in Banbhaidh
Banbhaidh is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain.
If you let a flat or house near Banavie station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What the job involves on each surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match suits the frame.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
