When to call us in Alyth
Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.
Signs it’s time to call us include:
- Black, perished sealant on frames
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
- Rushed sealant from a window installation
Around Alyth, as everywhere, window mastic is only as good as the preparation behind it.

Window mastic in Alyth
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you’re dealing with untidy mastic left by window fitters and whistling draughts around closed windows, we can help, on patio & French doors, window sills and composite doors alike.
Mastic can only go onto a dry joint, so outside work in Alyth depends on the weather. Tell us about access to all the windows and doors, upstairs included.
Every job is covered by a 12-month guarantee.

Window mastic in Alyth: local notes
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. Historic houses like Balhary House (about 1.6 miles south-east) are a reminder that the area around Alyth has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Parish Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Keep timber frames painted
- Look round the frames every year or so
- Keep jet washers away from the mastic
- Wash the frames with mild soapy water
Keep the new mastic undisturbed while it cures, for as long as we advise. Don’t point a pressure washer at the joints.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
What happens on the day
We bring everything the job needs with us. Once we’ve agreed what’s being done, we protect the area and start. It normally takes most of a day for a typical house, less for a few frames. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Clear the area around the work
- For business premises, tell us about site rules or sign-in
- For indoor joints, keep the area dry beforehand if you can

What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before booking.
Joints and surfaces we work on
- uPVC windows
- Timber windows & doors

How we quote for window mastic
The quote reflects the job in front of us. We take into account:
- How many areas need sealing
- Which sealant suits the joint
- Any mould that needs treating
- The old material and how stubborn it is
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
What we need to know
When you call or email, these details help:
- A few pictures by email, if you can
- Whether it has been sealed before
- Roughly how big the job is
- What the problem is, such as mould, gaps, leaks or cracking
It all starts with a short chat. Describe the problem, the location and the size of the job, and we’ll talk you through what we’d do. When it suits you, drop us a line at info@mrmastic.co.uk.
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

What the job involves on each surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we’ll tell you before going ahead, as that’s a job for a joiner.
Aluminium frames
Large aluminium doors have long joints down each side and across the head, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.
