Kirkintilloch Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Kirkintilloch and across East Dunbartonshire. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Gaps left after new windows were fitted
- Black, perished sealant on frames
- Leaking joints at the ends of sills
What happens on the day
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a morning for a couple of windows and a door. A visit in Kirkintilloch needs three things planned: access, parking and where the work is. Outdoor jobs need a dry day, so they can move if the weather turns.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Getting ready for the visit
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive

Advice
About our window mastic in Kirkintilloch
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. If you are dealing with cold air getting in at the frame edge and mastic that’s falling out in pieces, we can put it right.
Wind and rain in a Scottish town like Kirkintilloch find any gap around a frame. The windows facing the weather are usually the first to leak.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.

What else we do in Kirkintilloch
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Avoid harsh chemicals near the mastic
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
- Wash the frames with mild soapy water
Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Windows and doors in Kirkintilloch
The west of Scotland is wetter than the east, which means the mastic around window and door frames has to cope with a lot of rain. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Rented homes near Lenzie station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around Kirkintilloch, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When something else is needed
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Rotten timber, which needs a joiner first
- A sash or casement that won’t close properly
- A door that needs adjusting, rehanging or new seals
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Aluminium frames
- Timber windows & doors
- Patio & French doors
- Window sills
- uPVC windows
- Composite doors
Why it’s worth doing now in Kirkintilloch
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. Scottish weather finds any gap, and in a town like Kirkintilloch, failed outside joints soon let damp into walls. Indoors, failed sealant lets water into floors and ceilings.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Common problems we fix in Kirkintilloch
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Any of these means the joints need attention:
- Water coming in at the bottom corners of a door
- Sealant in the wrong colour for the frame
- Mastic that’s falling out in pieces
- Untidy mastic left by window fitters
Schools such as Kirkintilloch High School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

How long should I leave it?

Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so the joint is cleaned back first.

The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.
Different surfaces, different methods
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.
Timber windows & doors
Wood swells when it’s wet and shrinks when it dries, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
