Surface by surface
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Signs you need window mastic in Polmont
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Look out for these signs:
- A bead that doesn’t match the frame
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
- Draughts coming in around windows and doors
Rented homes near Polmont station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
What your quote should include
- How long the guarantee is
- Who turns up on the day
- Is the old sealant removed completely?
- How the joint is cleaned and prepared
The process
On the day, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before any work begins. The work generally takes anything from an hour or two to a full day, depending on how many frames there are. 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.
- 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.
- 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
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in
- Tell us about access, such as stairs, a lift or high-level joints

What affects the cost of window mastic
The quote reflects the job in front of us. We look at:
- Working hours on commercial sites
- The number of rooms or windows
- The product the joint needs
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
What to tell us when you ask for a quote:
- Any previous sealing or DIY work
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
- Access, such as stairs, a lift or height
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll take it from there.
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Your questions about window mastic in Polmont
I let a flat near Polmont station. Can you help?

Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Keep paint and stain on wooden frames in good order
- Use gentle cleaners on frames and sealant
- Avoid blasting the frames with a pressure washer
- Wipe condensation off the frames
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.

Windows and doors in Polmont
Polmont is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around window and door frames, especially on the side facing the sea. 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.
Managing a site like Graeme High School? Then its window and door frames need their mastic kept sound, just like a home’s.
