- Cracked sealant at the sill ends
- Hard, cracked sealant around windows
How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep solvents and bleach off the sealant
- Keep paint off silicone joints
- Make sure the drainage slots are not blocked
- Don’t aim a pressure washer at the joints
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
About our window mastic in Craigmore
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have gaps left after new windows were fitted and sealant in the wrong colour for the frame, we can put it right, on uPVC windows, composite doors and window sills alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Why act early in Craigmore
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a place like Craigmore, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
No two jobs are quite the same, 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.

Windows and doors in Craigmore
Craigmore 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Craigmore is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
If you live in an older home near Trinity Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you look after a building such as Rothesay Academy, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
Patio & French doors
Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

How the visit works
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. For a place like Craigmore, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- 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.
- 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
- Clear items away from the joints we’re working on
- Let us know about parking restrictions
- Keep children and pets away from the work area

Related advice
Craigmore: your questions answered
Does living near the coast affect window mastic in Craigmore?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Is Craigmore in your area for window mastic?
Yes, Craigmore 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.
I’m a tenant. Can you help?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can you do upstairs windows?
Yes, where it’s safe. For high or awkward windows, we will tell you what access is needed.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Is it messy?
We keep the work tidy. We protect what’s around the joints.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months.
Can I do it myself?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
