FAQs for Dunmore
Is Dunmore within the area you cover?
Yes, we do. Our work covers the whole of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Is window mastic in a coastal place like Dunmore any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Are you fully insured?
Yes, we’re fully insured for every job we do.
How long should I leave it?
Cure times vary by product. Before we leave, we will tell you the cure time.
Does someone need to be in?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
Window mastic in Dunmore
The mastic around a window or door seals the gap between the frame and the wall. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. If you’re dealing with damp patches on the reveal after heavy rain and untidy mastic left by window fitters, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.

Looking after it afterwards
So the new joints stay in good condition:
- Keep jet washers away from the mastic
- Keep solvents and bleach off the sealant
- Walk round the house once a year and look at the joints
- Ventilate rooms so frames do not stay wet inside
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Why act early in Dunmore
Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we’ll say so. In an older home around Dunmore, damp from a failed joint can get into timber and plaster.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.

Dunmore homes and the weather
Dunmore is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around window and door frames, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to Airth Parish Church and Churchyard include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Alloa Academy? Then its window and door frames need their mastic kept sound, just like a home’s.

When something else is needed
To be straight with you, some problems need a different trade:
- Damp coming through the wall itself rather than the frame joint
- Rotten timber, which needs a joiner first
- Misting between the panes of a double-glazed unit (that needs a new unit)
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

Signs you need window mastic in Dunmore
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. Backing rod sets the right depth.
Look out for any of the following:
- Leaking joints at the ends of sills
- Gaps between the frame and the inside reveal
- Mastic that has split away from the wall
- A bead that does not match the frame
For landlords with property near Alloa station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before you book
- Whether they seal over old material or remove it
- Whether the sealant suits the joint
- Who turns up on the day
- What guarantee comes with the work
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we tell you how long to leave it before we go. Outdoor work around Dunmore depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
How to prepare
- On commercial sites, let us know about site rules
- Mention any parking rules near the property
- Clear items away from the joints we are working on
