About our sand mastic in Newtyle
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. If you’re dealing with old cement repairs round a window that have failed and draughty sash windows at the surround, we can put it right, whatever the surface.
Mastic can only go onto a dry joint, so outside work in Newtyle depends on the weather. Let us know about access to every frame, including any upstairs.
Every job is covered by a one-year guarantee, wherever you are in Perth and Kinross.

Windows and doors in Newtyle
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional 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.
In and around Newtyle, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

For landlords and businesses
We work for landlords and letting agents as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
What happens on the day
All our tools and materials come with us in the van, so you do not need to buy or prepare anything. Once we have agreed what’s being done, the area is protected and the work begins. It normally takes anything from a few hours to a full day, depending on how many windows. Somewhere like Newtyle may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- Mention any parking rules near the property
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work

Different surfaces, different methods
Brick reveals
An open joint at a brick reveal lets weather in. New mastic seals the gap.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.

Why act early in Newtyle
Not every draught comes from the sashes themselves. Open mastic joints round the box can let air in and new mastic seals them. In a place like Newtyle, 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 normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
Why choose Mr Mastic in Newtyle

What we cannot put right
In fairness, there are a few things sealant will not fix:
- Sashes that need overhauling
- Cracked or broken glass
- Planning or listed building consent (your local planning authority decides)
If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer before booking.
