Window & door mastic in Dalgety Bay, Fife
Professional window mastic in and around Dalgety Bay, with old sealant always removed completely and a 12-month guarantee.
- Damp patches on the reveal after heavy rain
- A bead that does not match the frame
- Cold air getting in at the frame edge
Should I try it myself 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.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
Window mastic in Dalgety Bay
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. We work on patio & French doors, window sills and uPVC windows, and people most often call us about whistling draughts around closed windows and hard, cracked sealant around windows.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
You get a one-year guarantee, the same in Dalgety Bay as everywhere else we work.

Dalgety Bay: your questions answered
I let a flat near Dalgety Bay station. Can you help?
Yes. We work for letting agents and landlords as well as householders, and several properties can be quoted together. You can send an email to info@mrmastic.co.uk with the details for a clear quote.
Does the coastal weather in Dalgety Bay affect outside sealant?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. Walls facing the sea are usually the first to need attention.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We’ll tell you how long to leave the joint before we leave.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures.
Do you guarantee window mastic?
Yes. Each job is covered for 12 months.
Which products do you use?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
Will resealing my frames help with draughts?
It will if the frame joint is the problem. We find where the air is coming from before we reseal.
Can you do upstairs windows?
Yes, in most cases. We plan safe access before the job.
Window mastic in Dalgety Bay: local notes
Dalgety Bay 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. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Dalgety Bay station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Inverkeithing High School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

We also work for property managers and facilities teams in Dalgety Bay and across Fife. We can quote a run of properties together.
If you manage several properties in or around Dalgety Bay, several properties can be quoted together. Send us the addresses and the work at each.
Surface by surface
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
What we can’t put right
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window
- Broken hinges, locks or handles
Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly before you book.

Do you need window mastic in Dalgety Bay?
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.
It’s worth asking for a quote if you see:
- White mastic on grey or black frames
- Whistling draughts around closed windows
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
For an older house near a landmark such as St Bridget's Kirk, the joint between an old wall and a newer frame is normally the first place rain gets in.
What your quote should include
- When the joint can take water or movement
- Who turns up on the day
- Is VAT in the price?
- Whether you can choose the colour
