Window & door mastic in Carsie, Perth and Kinross
Mastic around window and door frames, sills and patio doors for homeowners, landlords and businesses in Carsie. Fully insured, ARBOMaster approved and guaranteed for a year.
- A bead that doesn’t match the frame
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
Common problems we fix in Carsie
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
People usually contact us after spotting something like this:
- White mastic on grey or black frames
- Gaps left after new windows were fitted
- Cracked internal joints between frame and plaster
- Leaking joints at the ends of sills
Around Carsie, as everywhere, window mastic is only as good as the preparation behind it.

Window mastic in Carsie, done properly
The new joint does not have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We work on composite doors, uPVC windows and aluminium frames, and common reasons people get in touch are untidy mastic left by window fitters and cracked or shrunken mastic around the frame.
In and around a place like Carsie, homes range from older stone-built cottages to newer houses. Wind-driven rain finds any gap around a frame or sill.
The work is covered for a year after we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a place like Carsie, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

The process
Most of a good job is in the preparation, so that’s where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, 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 normally less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky

Carsie 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. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Schools such as Blairgowrie High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Different surfaces, different methods
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
DIY versus a professional finish
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Use gentle cleaners on frames and sealant
- Keep timber frames painted
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
