Window mastic for homes and businesses in Borestone
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you’re dealing with white mastic on grey or black frames and whistling draughts around closed windows, we can put it right, whatever the surface.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Borestone questions
Do you work for landlords with property near Stirling station?
Yes, rental work is part of what we do. Just send an email to info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like Borestone?
Yes. Borestone is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Which products do you use?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Can you do several jobs on one visit?
Yes, and it often makes sense. Combining jobs makes good use of the visit.
Can you reach windows above the ground floor?
Yes, where it’s safe. For high or awkward windows, we’ll tell you what access is needed.
What should I tell you?
Tell us what needs doing and where, plus pictures if you have them. We will ask anything else we need to know.
Where is Mr Mastic based?
We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
When it isn’t the sealant
New sealant can’t fix everything, and we will tell you before any work starts. Sealant will not put right:
- Worn gaskets, brush seals or a door that has dropped
- Faulty window hardware
- Condensation trapped between the panes
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.
Surfaces we seal
- Patio & French doors
- Composite doors
- uPVC windows
- Aluminium frames
- Timber windows & doors
- Window sills
Window mastic in Borestone: local notes
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
If you let a flat or house near Stirling station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In and around Borestone, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

What the job involves on each surface
Composite doors
An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. We pay most attention there.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
What happens on the day
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes most of a day for a typical house, less for a few frames. Outdoor work around Borestone depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Mention any tricky access

Looking after it afterwards
To keep the joints looking good and working properly:
- Keep timber frames painted
- Look round the frames every year or so
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
Most silicone sealants will not take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Other services in Borestone
Work for landlords, hotels and businesses
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
Leave it or put it right?
A quick bead over the top of old mastic looks like an easy fix, 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. In a place like Borestone, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear price for the lot.
