Window Mastic in Greenfaulds
Window mastic for Greenfaulds and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
- Black, perished sealant on frames
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Don’t paint over the silicone
- Keep paint and stain on wooden frames in good order
- Do not aim a pressure washer at the joints
- Wipe condensation off the frames
Silicone cannot generally be painted, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
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. Early resealing stops it reaching that point.

What window mastic looks like in Greenfaulds
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Managing a site like Greenfaulds High School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Greenfaulds station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What else we do in Greenfaulds
What we are called out for in Greenfaulds
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. If the sealant can’t stretch, it splits.
Common reasons people contact us include:
- Untidy mastic left by window fitters
- A bead that doesn’t match the frame
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
In the older streets around St Mungo's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones aren’t used, as they can attack some metals. Neutral-cure sealant is the safe choice.
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
What affects the quote in Greenfaulds
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether old sealant or filler has to be cut out
- Any working-time requirements on site
- Any mould that needs treating
- The size of the job
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
What to tell us for a quote
You do not need to know the technical terms. Just tell us:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- If someone has resealed it before
- A few pictures by email, if you can

Why it’s worth doing now in Greenfaulds
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Exposed walls in smaller Scottish places take a lot of wind and rain, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.

How it works

Expect the work to take anything from an hour or two to a full day, depending on how many frames there are, and we tell you how long to leave it before we go.
