When to call us in Dalswinton
Some old mastic was never deep enough. Mastic that’s too thin cracks and drops out so we make sure the new mastic is the right thickness.
Most people get in touch after spotting one of these:
- Mastic round period door frames that has failed
- Failed mastic on an exposed elevation
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
In the older streets around Dalswinton Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Sand mastic in Dalswinton, done properly
For a listed home or one in a conservation area, ask your local planning authority if consent is needed before window work. Sand mastic is often favoured as a like-for-like material. If you are dealing with modern sealant on a period surround and failed mastic on an exposed elevation, we can help, on brick reveals, sash and case windows and period & listed homes alike.
Mastic can only go onto a dry joint, so outside work in Dalswinton depends on the weather. Tell us about access to all the windows and doors, upstairs included.
The work is covered for a year after we finish. If anything is not right with it, drop us a line at info@mrmastic.co.uk.

Will you come out to Dalswinton?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Are you insured?
Yes. We’re fully insured for domestic and commercial work.
How long does sand mastic take to harden?
It takes a while. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you’re redecorating the window, ask us first and we’ll advise.
How long does the job take?
A typical job takes a few hours per window, depending on the condition of the joints, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is it messy?
We keep the work tidy. Nearby surfaces are protected, and we clear up when we are done.
What we cannot put right
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant will not put right:
- Planning or listed building consent (your local planning authority decides)
- Decayed frames that need repair
- Putty and glazing repairs
If in doubt, email us at info@mrmastic.co.uk and we will say what we think before booking.
Surfaces we seal
- Brick reveals
- Stone surrounds
- Tenement windows
- Timber door frames
- Period & listed homes
- Sash and case windows
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
