Window Mastic in Pinwherry
Window and door frames in Pinwherry need attention? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Cold air getting in at the frame edge
- Mastic that has split away from the wall
- Gaps left after new windows were fitted
Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Air rooms to keep condensation down around windows
- Keep paint and stain on wooden frames in good order
- Keep paint off silicone joints
- Avoid harsh chemicals near the mastic
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Window mastic in Pinwherry, done properly
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with mastic that has split away from the wall and cold air getting in at the frame edge, we can help.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You’re covered for a year from the day we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

Pinwherry homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that. 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.
Rented homes near Barrhill station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What else we do in Pinwherry
The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house for a typical job. Outside jobs in Pinwherry need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- 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
- On commercial sites, let us know about site rules
- Let us know about stairs, lifts or work at height
- Try not to wet indoor joints just before the visit

What we are called out for in Pinwherry
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
People normally contact us when they notice something like this:
- Sealant in the wrong colour for the frame
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
- Mastic that has split away from the wall
In and around Pinwherry, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Pinwherry questions
Can you do window mastic in Pinwherry?
Yes, Pinwherry is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job, and we’ll send you a clear quote.
Is Pinwherry within the area you cover?
Yes, Pinwherry is covered. Our work covers the whole of Scotland, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it messy?
No. We protect the surfaces around the joints, and we tidy up before we go.
I rent my home. Can I book you?
Of course. Check with your landlord; we can send the quote to them too.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
What does window mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
When is the sealant fully cured?
Different products cure at different speeds, so please follow the time we give you.
How long does it take to reseal the windows on a house?
Allow most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
What the job involves on each surface
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it, where a rigid one would crack.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the sealant goes in between frame and wall.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
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 does not work out, we can still put it right.
