- What’s wrong with the joints now

How we handle sand mastic in Garvald
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We are often asked to deal with wind and rain getting in round a sash window and patchy fillers round a sash window, across sash and case windows, period & listed homes and brick reveals.
Many older Scottish homes still have timber windows set into stone walls. The sealant has to suit the stone, which rules out acetoxy silicones that can mark or attack it.
You get a 12-month guarantee, the same in Garvald as everywhere else we work.

When to call us in Garvald
Shallow joints are a common cause. Mastic that is too thin cracks and drops out so we make sure the new mastic is the right thickness.
Signs it’s time to call us include:
- Failed mastic on an exposed elevation
- Patchy fillers round a sash window
- A silicone bead on a sash window that spoils the look
- Mastic round period door frames that has failed
For landlords with property near East Linton station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What sand mastic looks like in Garvald

What the job involves on each surface
Brick reveals
Gaps between frame and brick let in rain and draughts. Renewing the mastic closes it.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.
How it works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work, and the visit is planned around that.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Keep children and pets away from the work area
- Move anything stored near the joints

FAQs for Garvald
Will you come out to Garvald?
Yes, we do. We work across all of Scotland, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Garvald for sand mastic?
Yes. Our work covers the whole of Scotland, and Garvald is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will send you a clear quote.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
Can tenants book the work?
Yes. Check with your landlord; we can send the quote to them too.
Do you have insurance?
Yes, we are fully insured for domestic and commercial work.
Should I use sand mastic or silicone?
We will help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Leave it or put it right?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new mastic stays put. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Call for a quick quote and we’ll explain what it covers.
