Window & door mastic in Greenhill, Falkirk
We cover Greenhill for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- A bead that doesn’t match the frame
- Draughty joints inside around the window
- Water coming in at the bottom corners of a door
Window mastic in Greenhill, done properly
If you can feel air around a shut window, the gap is often at the frame. A new joint stops the air getting through and quietens the whistle on windy days. If the draught is through the window seals instead, we’ll tell you. If you have a bead that doesn’t match the frame and mastic that has split away from the wall, we can put it right, whatever the surface.
Many older Scottish homes still have timber windows set into stone walls. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
All our work comes with our one-year guarantee, wherever you are in Falkirk.

Your questions about window mastic in Greenhill
Is Greenhill in your area for window mastic?
Yes, Greenhill is within the area we cover. We work across all of Scotland. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear quote.
Do you work for landlords with property near Camelon station?
Yes, rental work is part of what we do. Just email us at info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Do you work on first-floor windows?
Yes, in most cases. Access is planned before we start.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply email us at info@mrmastic.co.uk.
How long before the joint can be used?
Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used.
Can I paint over the new sealant?
Silicone generally will not take paint. Let us know beforehand, and we will use a paintable product where it suits.
Is the work guaranteed?
Yes, for 12 months. A yearly look at the joints helps them last.
How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes most of a day for a typical house, less for a few frames for a typical job. Around Greenhill, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Advice
Aftercare tips
Good habits help new joints last longer. Our tips:
- Avoid harsh chemicals near the mastic
- Check the mastic once a year
- Do not paint over the silicone
- Keep paint and stain on wooden frames in good order
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just drop us a line at info@mrmastic.co.uk.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What else we do in Greenhill
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
For anyone letting property in or around Greenhill, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
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.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Greenhill homes and the weather
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. 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.
If you live in an older home near St Helen's Parish Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Denny High School? Then the mastic around its windows and doors needs looking after like any other building’s.

When to call us in Greenhill
Some failures date back to when the windows were fitted. Sealant run over dust, wet brick or loose mortar never bonded as it should, so it comes away long before its time.
Any of these means the joints need attention:
- Mastic that has split away from the wall
- Gaps between the frame and the inside reveal
- Old mastic that has gone black or come away
- White mastic on grey or black frames
For landlords with property near Camelon station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
