Sand mastic for homes and businesses in Craobh Haven
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We work on timber door frames, period & listed homes and sash and case windows, and people most often call us about a silicone bead on a sash window that spoils the look and old cement repairs round a window that have failed.
Outdoor sealant needs a dry surface, so window work around Craobh Haven is planned around the weather, and longer journeys are planned in advance. Tell us about access to all the windows and doors, upstairs included.
You get a 12-month guarantee, the same in Craobh Haven as everywhere else we work.

What we are called out for in Craobh Haven
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows.
People generally contact us after spotting one of these:
- Mastic that needs renewing before redecorating
- Mastic round period door frames that has failed
- Mastic dropping out of the joint
- Modern sealant on a period surround
Whether the job is in Craobh Haven itself or nearby, the right material for each joint matters as much as a neat finish.
Questions to ask before you book
- What preparation is included
- Are they insured?
- Which colour the sealant will be
- What product goes in the joint
The process
When we arrive, we start by going over the job with you. Surfaces next to the work are protected before any work starts. The work normally takes a few hours for a single window, longer for several. For a place like Craobh Haven, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
- Clear the area around the work
Ask for a quote
Asking for a quote is easy: tell us what needs doing and where and its rough size. Photos by email help us understand the job, and we will take it from there.
Related advice
Leave it or put it right?
If you are redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps, and the new mastic is traditionally left unpainted. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

FAQs for Craobh Haven
Does the coastal weather in Craobh Haven affect outside sealant?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Can you do sand mastic in Craobh Haven?
Yes. We work across all of Scotland, and Craobh Haven is part of that. You can drop us a line at info@mrmastic.co.uk and let us know what needs doing, and we will give you a clear price.
What does sand mastic cost?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator and we are fully insured too.
How long does sand mastic take?
Typically it takes anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer, and we’ll tell you how long to expect.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Sand mastic in Craobh Haven: local notes
Craobh Haven is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic.
Around Craobh Haven, as everywhere, sand mastic is only as good as the preparation behind it.
