How we handle sand mastic in Middleton
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on sash and case windows, timber door frames and period & listed homes, and people most often call us about draughts and rain around sash boxes and mastic worn away on windows facing the weather.
Outdoor sealant needs a dry surface, so window work around Middleton is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
There’s a 12-month guarantee on every job, whatever its size.

Looking after it afterwards
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Keep modern sealant off the mastic
- Sort the mastic before the decorators arrive
- Check with your local planning authority if your home is listed
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Renewing mastic before redecorating saves doing it twice. Painting over failed mastic hides the problem for a while.

The process
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the amount of work. Outdoor work around Middleton depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Move anything stored near the joints
- Mention any tricky access
- Mention any sign-in or site rules at work premises

Windows and doors in Middleton

Rented homes near Dunkeld & Birnam station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.

Do you need sand mastic in Middleton?
Most of it is simply age. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
Common reasons people contact us include:
- Cement or filler used on old window joints that has cracked
- Mastic dropping out of the joint
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
In the older streets around Old Parish Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
