Surface by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
About our window mastic in Elderslie
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through and quietens the whistle on windy days. Where the air is getting in through the window itself, we will say so. If you have a bead that doesn’t match the frame and mastic that’s falling out in pieces, we can help, on aluminium frames, window sills 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.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When something else is needed
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:

- A frame that has rotted at the joint
- Penetrating damp from a failed cavity tray or render
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Your questions about window mastic in Elderslie
Will you come out to Elderslie?
Yes. Elderslie is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Johnstone station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Do you hold any approvals?
Yes. We are approved under the ARBOMaster scheme.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can you match the sealant to my frames?
Yes, we choose a colour to suit the frame. Anthracite grey, black, brown and white cover most frames, with clear as an option.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can resealing stop a draught around my window?
It will if the frame joint is the problem. We check where the draught is before work begins.
Can you do upstairs windows?
Yes, where it’s safe. Higher or awkward frames may need extra access, and we’ll confirm what’s needed.
Why it’s worth doing now in Elderslie
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why Elderslie clients choose us
- You choose the colour before work begins
- An ARBOMaster approved applicator
- Old sealant always removed completely
- Tidy, careful work

Landlords, agents and businesses in Elderslie
If you manage several properties in or around Elderslie, several properties can go on one quote. Send us the addresses and the work at each.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
The process
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes anything from an hour or two to a full day, depending on how many frames there are. In smaller Scottish places, parking is generally less of an issue than access and distance. Let us know how to find you and how to reach the joints.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- 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
- Tell us about access, such as stairs, a lift or high-level joints
- Mention any leaks or damp you’ve noticed
- Mention any parking rules near the property
Getting a quote

Advice
Window mastic in Elderslie: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. 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.
Homes close to East Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Gleniffer High School, larger buildings have plenty of frames, and the mastic around each one ages.

Signs you need window mastic in Elderslie
Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid can’t flex. That is what backing rod is for.
Any of these means the joints need attention:
- Whistling draughts around closed windows
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
- Cracked or shrunken mastic around the frame
If you let a flat or house near Johnstone station, renewing tired window mastic between tenants heads off draught and damp complaints.
