Window mastic in Milton
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have rushed sealant from a window installation and hard, cracked sealant around windows, we can put it right, on timber windows & doors, uPVC windows and patio & French doors alike.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Exposed frames and sills take the full force of wind-driven rain.
Each job carries a 12-month guarantee, whatever its size.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Avoid blasting the frames with a pressure washer
- Keep solvents and bleach off the sealant
- Keep drainage slots and sill grooves clear
- Paint up to the joint, not over it
Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Why deal with it now?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You will have a clear quote before any work starts, so you know where you stand.

What we do, step by step
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to a full day, depending on how many frames there are. Outdoor work around Milton depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. 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.
Before we arrive
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints

Advice
What we’re called out for in Milton
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, so it comes away long before its time.
Signs it’s time to call us include:
- Draughty joints inside around the window
- Whistling draughts around closed windows
- Hard, cracked sealant around windows
- Water coming in at the bottom corners of a door
For jobs in and around Milton, choosing the right material for each joint is as important as a tidy finish.
What to look for in a quote
- How the joint is cleaned and prepared
- Whether all the old sealant comes out first

- Is VAT in the price?
What affects the quote in Milton
For a quick quote, just ask. The main things that affect it are:

What window mastic looks like in Milton
Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.

Surface by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
