Sand mastic for sash & case windows in Inverinan, Argyll and Bute
Professional sand mastic in and around Inverinan, with every bit of old sealant taken out first and a 12-month guarantee.
- Tired mastic found when preparing windows for paint
- Cement or filler used on old window joints that has cracked
- Modern sealant on a period surround
Sand mastic in Inverinan, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. Common call-outs are for tired mastic found when preparing windows for paint and modern sealant on a period surround, across period & listed homes, stone surrounds and tenement windows.
Across smaller places in Scotland, homes range from stone and harled cottages to newer houses, many standing in the open. Wind-driven rain finds any gap around a frame or sill, so the mastic there works hard.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

Timber door frames
A neat sand mastic joint round a front door suits a period home.
Period and listed homes
Many older homes were built with sand mastic round the windows. If your home is listed, ask your local planning authority about consent.
How it works
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours per window, depending on the condition of the joints. Around Inverinan, distance and access matter more than parking. Let us know how to find you and how to reach the joints.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- On commercial sites, let us know about site rules

Sand mastic in Inverinan: local notes
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. Sash and case windows are common in older Scottish homes, often pointed into the wall with traditional sand mastic.
In and around Inverinan, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint. For jobs in and around Inverinan, choosing the right material for each joint is as important as a tidy finish.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
Avoid painting over the new mastic, which is the traditional advice. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
