When to call us in Arnprior
Decorating can disturb tired mastic. Many people find it crumbling when they prepare the windows.
People normally contact us when they notice one of these:
- Old sand mastic that has cracked, crumbled or fallen out
- Draughts and rain around sash boxes
- Mastic round period door frames that has failed
- Window mastic to renew ahead of painting
Whether the job is in Arnprior itself or nearby, the right material for each joint matters as much as a neat finish.

Sand mastic in Arnprior
Fresh sand mastic forms a skin quite soon but full hardening takes longer. Traditional guidance is not to paint over it and we will advise if you are redecorating. Common call-outs are for gaps between timber frames and stone or brick and patchy fillers round a sash window, across stone surrounds, brick reveals and period & listed homes.
In and around a place like Arnprior, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How we quote for sand mastic
Call for a quick quote. What matters most is:
- Any working-time requirements on site
- How many rooms, windows or areas are involved
- The size of the job
- How much old sealant there is and how hard it is to remove
Doing several joints on one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.
Asking for a quote
When you contact us, these details help:
- Access, such as stairs, a lift or height
- If it’s domestic, commercial or a hotel
- Any previous sealing or DIY work
- What’s wrong with the joints now
For a quote, email us at info@mrmastic.co.uk and tell us where the job is and what the problem looks like. We will send you a clear quote before any work starts.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a single window, longer for several, depending on the size of the job. Outside jobs in Arnprior need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
Preparing for the visit
- Clear items away from the joints we’re working on
- Let us know about earlier repairs to the joints
- Let us know about stairs, lifts or work at height

Frames and glazing around Arnprior
Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that. The west of Scotland is wetter than the east, so there’s plenty of rain for the mastic around older windows and doors to keep out.

Why deal with it now?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. In a place like Arnprior, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and give you a clear price before any work starts.
