What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it usually takes a few hours for a few frames, or a day or more for a whole house. Around Balmirmer, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Clear the area around the work
- Mention if the joints have been sealed before
- Mention any tricky access

Window mastic in Balmirmer, done properly
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for gaps left after new windows were fitted and mastic that has split away from the wall, on uPVC windows, aluminium frames and timber windows & doors.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant. Neutral-cure sealant is the safe choice.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep timber frames painted
- Use gentle cleaners on frames and sealant
- Don’t paint over the silicone
- Walk round the house once a year and look at the joints
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What sealant work cannot fix
Before you book, it’s worth knowing the limits too:
- Soft or decayed wood in the frame
- A sash or casement that won’t close properly
- Worn gaskets, brush seals or a door that has dropped
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal

- Composite doors
- Aluminium frames

Questions from Balmirmer
Is Balmirmer within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you help a landlord with a rental near Carnoustie station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints.
Do you hold any approvals?
Yes. We’re approved under the ARBOMaster scheme, which is run for the Arbo sealant brand.
Can new window sealant be painted?
Most silicone cannot be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
Why it’s worth doing now in Balmirmer
Not every sealant suits a window. Interior caulk and bathroom silicone aren’t made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

What else we do in Balmirmer
What window mastic looks like in Balmirmer
Balmirmer is within about 2 miles 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. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Rented homes near Carnoustie station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. In and around Balmirmer, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Should I try it myself first?
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
