Leave it or put it right?
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. In an older home around Birniehill, damp from a failed joint can get into timber and plaster, which is a far bigger job than the sealant.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The job generally takes most of a day for a typical house, less for a few frames. Around Birniehill, distance and access matter more than parking. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit

Advice
Do you need window mastic in Birniehill?
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
The most common problems we see are:
- Gaps left after new windows were fitted
- Cold air getting in at the frame edge
- Draughty joints inside around the window
- Cracked sealant at the sill ends
If you let a flat or house near East Kilbride station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Is Birniehill in your area for window mastic?

Yes, landlords and agents are among the people we work for. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long before the joint can be used?
Cure times vary by product and the temperature. Before we leave, we’ll tell you the cure time.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before we start.
Is the new sealant paintable?
Not if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Aftercare tips
So the new joints stay in good condition:
- Check the mastic once a year
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Ventilate rooms so frames don’t stay wet inside
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
Birniehill homes and 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. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around window and door frames to keep out.
Schools such as Mount Cameron Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What sealant work cannot fix
New sealant cannot fix everything, and we’d rather say so up front. It won’t solve:
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
- A door that needs adjusting, rehanging or new seals
If in doubt, drop us a line at info@mrmastic.co.uk and we will say what we think before you book.
