About our window mastic in New Luce
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on timber windows & doors, aluminium frames and uPVC windows, and people most often call us about gaps where the sill meets the wall and cracked internal joints between frame and plaster.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill.
You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What else we do in New Luce
Should I try it myself first?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Where are you based?
Mr Mastic is based in Crawley. We cover New Luce and the rest of Dumfries and Galloway.
Do you work for hotels and businesses?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Are you insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Do I have to be there?
That depends on where the joints are. For work indoors, someone needs to let us in.
Will the old sealant be removed?
Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.
Windows and doors in New Luce
Many older homes in Scotland have sash and case windows, 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 sound outside sealant is part of that.
In and around New Luce, as anywhere, good window mastic starts with a clean, dry, properly prepared joint. For jobs in and around New Luce, choosing the right material for each joint is as important as a tidy finish.

Different surfaces, different methods
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as a joiner will need to deal with it.
Why act early in New Luce
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Around New Luce, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we’ll go through it with you.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep jet washers away from the mastic
- Check the mastic once a year
- Use gentle cleaners on frames and sealant
- Don’t use solvent cleaners on the joint
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
