New Monkland 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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
If you live in an older home near Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Airdrie Academy, its window and door frames need their mastic kept sound, just like a home’s.

Window mastic in New Monkland
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Common call-outs are for hard, cracked sealant around windows and mastic that’s falling out in pieces, on composite doors, timber windows & doors and uPVC windows.
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.
Every job is covered by our one-year guarantee.

Do you work on first-floor windows?

Will resealing my frames help with draughts?

Do I have to be there?
We need access to the joints, so we’ll agree that with you when we book. For inside work, that normally means someone being in.
How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
When it isn’t the sealant
Some problems need a builder, plumber or other trade rather than us:
- A frame that has rotted at the joint
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
If you’re not sure, just send an email to info@mrmastic.co.uk and we’ll give you a straight answer before booking.

Should I try it myself first?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
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 does not work out, we can still put it right.
Work for landlords, hotels and businesses
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can be quoted together.

Signs you need window mastic in New Monkland
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.

- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
- Gaps left after new windows were fitted
Rented homes near Airdrie station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

The process
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Outdoor work around New Monkland depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.
Before we arrive
- Tell us if parking is tricky
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints
