Window Mastic in Markinch
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Markinch. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Sealant in the wrong colour for the frame
Looking after it afterwards
Looking after new joints is easy:
- Clean frames with a soft cloth and soapy water
- Do not paint over the silicone
- Air rooms to keep condensation down around windows
- Don’t aim a pressure washer at the joints
Try not to touch the new joint while it cures, for as long as we advise. Keep jet washers away from the frames.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
About our window mastic in Markinch
Around Markinch we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you have whistling draughts around closed windows and draughty joints inside around the window, we can help, on aluminium frames, timber windows & doors and composite doors alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Every job comes with a one-year guarantee, wherever you are in Fife.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Why act early in Markinch
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Around Markinch, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.

Frames and glazing around Markinch
Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
For site and facilities teams at buildings such as Auchmuty High School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Markinch station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

What sealant work cannot fix
New sealant can’t fix everything, and we’ll tell you before any work starts. Sealant will not put right:
- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
- Rotten timber, which needs a joiner first

Questions from Markinch
Do you cover Markinch for window mastic?
Yes. We work across all of Scotland, and Markinch is part of that. You can email us at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
I let a flat near Markinch station. Can you help?
Yes. We work for landlords and agents as well as homeowners. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we’ll give you a clear price.
Can you seal over the old sealant?
No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. It all has to come out first.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
Can you do the inside joint as well?
Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.

We protect the rest, and the work takes a few hours for a few frames, or a day or more for a whole house for a typical job. Around Markinch, distance and access matter more than parking. Let us know how to find you and how to reach the joints, and the visit is planned around that.
