About our window mastic in Craigton
Frames and walls do not move together. 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. Common call-outs are for white mastic on grey or black frames and water coming in at the bottom corners of a door, across window sills, aluminium frames and composite doors.
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.
A one-year guarantee comes as standard, so you are not left on your own once the job is done.

What happens on the day
When we get to you, 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 a few hours for a handful of frames, longer for a whole house. Outdoor work around Craigton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- Each frame is looked over and we agree which ones need resealing.
- 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
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Landlords, agents and businesses in Craigton
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.
Frames and glazing around Craigton
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. Dundee’s older tenements are sandstone, and the city sits on the Firth of Tay.
Letting a property close to Barry Links station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Parish Church And Burial-Ground, the joint between an old wall and a newer frame is usually the first place rain gets in.

Why it’s worth doing now in Craigton
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 peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Around Craigton, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
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 make a difference, and we will explain the quote if you ask.

How to look after the new joints
To keep the joints looking good and working properly:
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
- Wash the frames with mild soapy water
- Keep timber frames painted
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just email us at info@mrmastic.co.uk.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.

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.
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.
What we cannot put right
Sealant is not the answer to every problem, and we will tell you before work begins. Sealant won’t put right:
- Faulty window hardware
- A failed sealed unit that has misted up
- Damp coming through the wall itself rather than the frame joint
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
