About our window mastic in Westhill
Colour matters on a frame. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. We’re often asked to deal with draughts coming in around windows and doors and white mastic on grey or black frames, on uPVC windows, patio & French doors and composite doors.
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.
Our work is backed for twelve months, in Westhill and everywhere else we cover.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why it’s worth doing now in Westhill
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a place like Westhill, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear quote for the lot.

Landlords and agents in Westhill can book us as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

How we quote for window mastic
Your quote is based on your job. We look at:
- Whether the work is at height
- How much old sealant there is and how hard it is to remove
- The size of the job
- Mould in or behind the old joints
The cost depends on the size of the job, how much old material has to come out and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
What to tell us for a quote
When you contact us, it’s useful to know:
- A few pictures by email, if you can
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- If it’s domestic, commercial or a hotel
We don’t publish a price list. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
How to look after the new joints
Aftercare is simple:
- Keep solvents and bleach off the sealant
- Keep paint and stain on wooden frames in good order
- Check the mastic once a year
- Keep jet washers away from the mastic
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. A new joint closes it up.
What we’re called out for in Westhill
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and timber moves with moisture as well as temperature.
People usually contact us after spotting one of these:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Black, perished sealant on frames
- Hard, cracked sealant around windows
Schools such as Westhill Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Mention tracks, gates, ferries or anything else about the route.

- We remove the old mastic and clean the frame edge and wall.
- 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.

Westhill homes and the weather
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. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
