FAQs for Braehead

Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear price.
Is Braehead in your area for window mastic?

Is the new sealant paintable?
It depends on the sealant. Some hybrid sealants can be painted; silicone can’t. Tell us if you’re decorating and we will choose accordingly.

Window mastic in Braehead, done properly
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include sealant in the wrong colour for the frame and gaps where the sill meets the wall, across composite doors, window sills and patio & French doors.
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.
Big or small, it’s backed by our one-year guarantee.

Common problems we fix in Braehead
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Most people get in touch when they notice something like this:
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Gaps left after new windows were fitted
For landlords with property near Carstairs station, renewing tired window mastic between tenants heads off draught and damp complaints.

Other services in Braehead
Surface by surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A neat, narrow bead in a colour to match keeps the clean look.
What we cannot put right
To be straight with you, there are a few things sealant will not fix:
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
- A failed sealed unit that has misted up
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

The process
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. 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.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we’re working on
- Tell us about any water getting in

Advice
What affects the cost of window mastic
We quote each job individually. This is what makes a difference:
- How many areas need sealing
- The size of the job
- Any working-time requirements on site
- Which sealant suits the joint
The cost depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- What the problem is, such as mould, gaps, leaks or cracking
- Any access issues, like height or stairs
- Where the job is, and your postcode
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Why deal with it now?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first.

What window mastic looks like in Braehead
Sash and case windows are common in older Scottish homes, 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 failed outside joints work against that.
In the older streets around Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Can I do it myself?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
