About our window mastic in Milton
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. If the draught is through the window seals instead, we will tell you. Common call-outs are for mastic that’s falling out in pieces and rain getting in at the frame or under the sill, across aluminium frames, uPVC windows and window sills.
Scotland’s cities are full of stone-built tenements and terraces, in sandstone or granite. Stone needs a sealant that suits it, so acetoxy silicones, which can attack some stone, are best avoided.
The work is covered for a year after we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Frames and glazing around Milton
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. With historic houses such as Tenement House (about 2.1 miles south) nearby, there’s older building stock in the area around Milton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Historic houses such as Tenement House, about 2.1 miles south, show how far back building around Milton goes, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as John Paul Academy, the mastic around its windows and doors needs looking after like any other building’s.

The process
When we arrive, we look over the joints with you first, so there are no surprises. Surfaces next to the work are protected before we start. The work usually takes anything from an hour or two to a full day, depending on how many frames there are. Inside a flat in Milton, the job is planned with you; outside, shared parts may need the factor or other owners involved. It helps to know which it is when you get in touch.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Milton questions
Do you work for landlords with property near Possilpark & Parkhouse station?
Yes, we work for landlords and letting agents. Just email us at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear quote.
Can you do window mastic in Milton?
Yes, Milton is within the area we cover. Our work covers the whole of Scotland. You can send an email to info@mrmastic.co.uk and let us know what needs doing.
What information do you need?
A short description and the location, plus photos if you have them. We’ll ask anything else we need to know.
Will resealing my frames help with draughts?
In many cases. Air often gets in between the frame and the wall, and resealing inside and out closes it.
Do you work on first-floor windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does it take to reseal the windows on a house?
The work takes a few hours for a few frames, or a day or more for a whole house. Access and how stubborn the old mastic is affect the time most.
Common problems we fix in Milton
Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.
If you can see any of these, it’s time to have the joints looked at:
- Gaps left after new windows were fitted
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
- Gaps between the frame and the inside reveal
Rented homes near Possilpark & Parkhouse station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

What affects the cost of window mastic
Your quote is based on your job. We take into account:
- The old material and how stubborn it is
- Which sealant suits the joint
- Working hours on commercial sites
- Mould in or behind the old joints
Combining jobs into one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.
Asking for a quote
When you contact us, it’s useful to know:
- Roughly how big the job is
- Any previous sealing or DIY work
- Any access issues, like height or stairs
- The problem you’ve noticed
A good description makes for an accurate quote. Tell us where the job is, what’s wrong and how much there is.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Ventilate rooms so frames do not stay wet inside
- Walk round the house once a year and look at the joints
- Don’t use solvent cleaners on the joint
- Wash the frames with mild soapy water
Silicone cannot normally be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
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.
Leave it or put it right?
Not every sealant suits a window. Interior caulk and bathroom silicone are not made for exterior frame joints. An exterior, low-modulus sealant stays flexible in sun and frost. In a Scottish city tenement, failed sealant affects more than one flat: a leak can come through the ceiling below, and gaps in shared walls or fire-rated joints matter to every flat.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
