Window mastic for homes and businesses in Kirkcaldy
Around Kirkcaldy we seal all kinds of frames: 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. If you have rain getting in at the frame or under the sill and old mastic that has gone black or come away, we can help, on window sills, patio & French doors and uPVC windows alike.
Harled walls are common in Scottish towns like Kirkcaldy, and sealing a frame against rough harling takes a sealant that grips and moves. A thin bead that hasn’t been worked into the surface soon lets water behind it.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How it works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. In a Scottish town like Kirkcaldy, parking is usually straightforward, though older centres can be tighter. If you are in a flat with a shared stair or a door entry system, let us know when you book.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, 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.
Before we arrive
- Move anything stored near the joints
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

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.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. Each is cleaned, backed where deep and resealed.
Common questions in Kirkcaldy
Do you cover Kirkcaldy for window mastic?
Yes, Kirkcaldy is within the area we cover. Our work covers the whole of Scotland. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Is window mastic in a coastal place like Kirkcaldy 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.
Does the work come with a guarantee?
Yes, with our 12-month guarantee. Keeping drainage clear and checking the joints yearly helps them last.
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.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Let us know about access when you ask for a quote so we can plan the job.
Do you seal inside as well as outside?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do, and we are fully insured.
Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
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. Everything old must be removed first.
Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep paint off silicone joints
- Look round the frames every year or so
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
A yearly look round the frames is enough. Cracks and lifting edges are easy to spot early.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Common problems we fix in Kirkcaldy
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
Common reasons people contact us include:
- Hard, cracked sealant around windows
- Cold air getting in at the frame edge
- Rain getting in at the frame or under the sill
- Draughty joints inside around the window
Managing a site like Kirkcaldy High School? Then its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- What product goes in the joint
- Which colour the sealant will be
- What happens if they find a problem under the old sealant
- The length of the guarantee
What window mastic looks like in Kirkcaldy
Kirkcaldy is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces 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.
Homes close to St Andrews Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Kirkcaldy station, renewing tired window mastic between tenants heads off draught and damp complaints.
