Window mastic for homes and businesses in Gairloch
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you’re dealing with gaps left after new windows were fitted and old mastic that has gone black or come away, we can put it right, on patio & French doors, aluminium frames and composite doors alike.
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.
Whatever the size of the job, it’s backed by our one-year guarantee in Gairloch and across Highland.

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Landlord and commercial work in Gairloch
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
What window mastic looks like in Gairloch
Gairloch is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Around Gairloch, as everywhere, window mastic is only as good as the preparation behind it.

Questions from Gairloch
Do you cover Gairloch for window mastic?
Yes. Our work covers the whole of Scotland, and Gairloch is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.
Does living near the coast affect window mastic in Gairloch?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you seal the gap between the frame and the plaster indoors?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We do one or both.
Is it OK to seal over old sealant?
No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What information do you need?
A short description and the location. We will ask anything else we need to know.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Can new window sealant be painted?
Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
How the visit works
Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Outdoor work around Gairloch depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- 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.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Mention any parking rules near the property
- Try not to wet indoor joints just before the visit
- Tell us about any previous sealing or DIY attempts
How to get a quote
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Related advice
Signs you need window mastic in Gairloch
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Most people get in touch when they notice one of these:
- Rain getting in at the frame or under the sill
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
- Draughts coming in around windows and doors
Managing a site like Gairloch High School? Then its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- Whether they’re fully insured
- What happens if they find a problem under the old sealant
Quotes for window mastic in Gairloch
Your quote is based on your job. We take into account:
- How many rooms, windows or areas are involved
- When we can work, for business premises
- Whether old sealant or filler has to be cut out
- The product the joint needs
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Asking for a quote
When you call or email, these details help:
- What the problem is, such as mould, gaps, leaks or cracking
- If it’s domestic, commercial or a hotel
- Whether it has been sealed before
- Where the property is
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. 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.
Combining jobs into one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.
