How we handle window mastic in Crombie
Homes in Crombie have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We work on timber windows & doors, composite doors and uPVC windows, and people most often call us about draughty joints inside around the window and hard, cracked sealant around windows.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid harsh chemicals near the mastic
- Keep paint off silicone joints
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
Most silicone sealants won’t take paint, so mention any painting plans before work begins. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Frames and glazing around Crombie
Crombie is close to 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. Historic houses like Pittencrieff House (about 2.7 miles north-east) are a reminder that the area around Crombie has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For landlords with property near Dunfermline City station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

The process
When we arrive, we start by going over the job with you, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Crombie may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- 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.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints

How we quote for window mastic
For a quick quote, just ask. The main things that affect it are:
- The number of rooms or windows
- Whether the work is at height
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites
Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- A few pictures by email, if you can
- Any access issues, like height or stairs
- What’s wrong with the joints now
- The type of property
Every job is quoted individually, so start by telling us what you need. Just drop us a line at info@mrmastic.co.uk with the details and send pictures if you have them.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works and we will give you a quote.
If you manage several properties in or around Crombie, several properties can go on one quote. Send us the addresses and the work at each.
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
What a professional job adds is preparation and the right 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.
Signs you need window mastic in Crombie
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
People normally contact us after spotting one of these:
- Draughty joints inside around the window
- Cracked sealant at the sill ends
- Water coming in at the bottom corners of a door
- Mastic that’s falling out in pieces
In the older streets around Cairneyhill Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Crombie questions
Is window mastic in a coastal place like Crombie any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
I let a flat near Dunfermline City station. Can you help?

Why it’s worth doing now in Crombie
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. Problems with the glass or gaskets are for a window company, and we’ll say so. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part.
