Bridge of Dee Window Mastic
Problem with your window and door frames in Bridge of Dee? We remove the old material, prepare the joints and seal them properly.
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
- Gaps left after new windows were fitted
Window mastic for homes and businesses in Bridge of Dee
There are two joints on most windows. 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. We work on uPVC windows, aluminium frames and composite doors, and common reasons people get in touch are untidy mastic left by window fitters and gaps between the frame and the inside reveal.
Mastic can only go onto a dry joint, so outside work in Bridge of Dee depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Whatever the size of the job, it’s backed by our 12-month guarantee in Bridge of Dee and across Dumfries and Galloway.

Bridge of Dee homes and the weather
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
For jobs in and around Bridge of Dee, choosing the right material for each joint is as important as a tidy finish.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for a few frames, or a day or more for a whole house. 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.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- Tell us if parking is tricky
- Keep children and pets away from the work area

What sealant work cannot fix
It helps to know what we can’t do:
- Draughts through the window seals rather than the frame
- Damp problems in the wall away from the window
- Soft or decayed wood in the frame
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.
What we seal
- Patio & French doors
- uPVC windows
- Timber windows & doors
- Aluminium frames
- Composite doors
- Window sills
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.

Signs you need window mastic in Bridge of Dee
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- Black, perished sealant on frames
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
In and around Bridge of Dee, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why it’s worth doing now in Bridge of Dee
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished. 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 we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Different surfaces, different methods
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
