Sand mastic for Crook of Devon, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Gaps where the frame meets the masonry
- Weathered mastic on the most exposed windows
- Mastic that needs renewing before redecorating
How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Have rotten timber repaired before new mastic goes in
- Avoid heavy scraping on the mastic joint
- Look over the window mastic once a year
- Do not run silicone over sand mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Sand mastic in Crook of Devon
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we will talk through which suits your home. We work on period & listed homes, sash and case windows and timber door frames, and people most often call us about old sand mastic that has cracked, crumbled or fallen out and draughty sash windows at the surround.
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.
Your job is guaranteed for a year, as with all our work.

Crook of Devon: your questions answered
Do you cover Crook of Devon for sand mastic?
Yes. We work across all of Scotland, and Crook of Devon is part of that. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
What guarantee comes with sand mastic in Crook of Devon?
All our work, in Crook of Devon and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Is it OK to seal over old sealant?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Will it make a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. Period windows in stone or brick generally suit sand mastic and newer frames normally get a flexible sealant.
How it works
The work is kept neat and contained to the joints we are treating, so you can carry on as normal. The job usually takes a few hours for a single window, longer for several, and we explain the cure time before we leave. Outdoor work around Crook of Devon depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Let us know if you’ve seen damp or leaks

Advice
What sand mastic looks like in Crook of Devon
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
Homes close to St Serf's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What affects the quote in Crook of Devon
We quote each job individually. This is what makes a difference:
- Mould in or behind the old joints
- The type of sealant required
- The number and length of the joints
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all make a difference.

- The problem you’ve noticed
- A few pictures by email, if you can
- How we’d reach the joints

Do you need sand mastic in Crook of Devon?
Shallow joints are a common cause. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Look out for these signs:
- Modern sealant on a period surround
- Patchy fillers round a sash window
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
In and around Crook of Devon, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.
