Sand Mastic in Coillore

- A silicone bead on a sash window that spoils the look
- Old cement repairs round a window that have failed
What we cannot put right
In fairness, there are a few things sealant will not fix:
- Crumbling stone or brickwork round the window
- Putty and glazing repairs
- Planning or listed building consent (your local planning authority decides)

Sand mastic in Coillore, done properly
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we’ll talk through which suits your home. Common call-outs are for gaps where the frame meets the masonry and cement or filler used on old window joints that has cracked, on stone surrounds, sash and case windows and brick reveals.
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.
You get a 12-month guarantee, the same in Coillore as everywhere else we work.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
When we arrive, we start by going over the job with you, so there are no surprises. Surfaces next to the work are protected before work begins. The work generally takes anything from a few hours to a full day, depending on how many windows. Outside jobs in Coillore need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height

Advice
Signs you need sand mastic in Coillore
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Most people get in touch when they notice something like this:
- Mastic round period door frames that has failed
- Window mastic to renew ahead of painting
- Weathered mastic on the most exposed windows
- Cement or filler used on old window joints that has cracked
In and around Coillore, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

The price is agreed before any work begins. It’s based on:
- When we can work, for business premises
- The size of the job

Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, drop us a line at info@mrmastic.co.uk and we’ll give you an honest view and a quote.

Other services in Coillore
What sand mastic looks like in Coillore
Coillore is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and failed outside joints work against that.
Whether the job is in Coillore itself or nearby, the right material for each joint matters as much as a neat finish.
Coillore is in Highland. Jobs in Coillore get the same care as everywhere else we work: old sealant removed completely, careful preparation and a one-year guarantee. Across Highland, we cover 253 places, Coillore among them.

Aftercare tips
To keep the joints looking good and working properly:
- Keep modern sealant off the mastic
- Take care around the mastic when scraping paint
- Plan mastic work ahead of painting
- Ask us before painting near the mastic
Do not run silicone over the new mastic. If you see a crack, ask us to take a look before trying a quick fix.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
For landlords and businesses
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
