Windows and doors in Blackford
Many older homes in Scotland have sash and case windows, often pointed into the wall with traditional sand mastic. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
Rented homes near Gleneagles station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic for homes and businesses in Blackford
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Common call-outs are for silicone on a period window that looks wrong and patchy fillers round a sash window, across stone surrounds, sash and case windows and timber door frames.
In and around a place like Blackford, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.

What affects the quote in Blackford
Call for a quick quote. What matters most is:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- How easy the joints are to reach
- Which sealant suits the joint
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk and we will give you an honest view and a quote.
What we need to know

- Photos by email, if that’s easy

What the job involves on each surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
What happens on the day
We bring everything the job needs with us, so you do not need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. It normally takes a few hours for a single window, longer for several. Outside jobs in Blackford need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling 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.
- We dress the surface so it sits neatly against the masonry.
Before we arrive
- Move anything stored near the joints
- On commercial sites, let us know about site rules
- Keep children and pets away from the work area

Signs you need sand mastic in Blackford
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Common reasons people contact us include:
- Open joints round the window box
- Weathered mastic on the most exposed windows
- A silicone bead on a sash window that spoils the look
- Patchy fillers round a sash window
Around Blackford, as everywhere, sand mastic is only as good as the preparation behind it.

- Which sealant they’ll use, and why
What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.
Doing several joints on one visit is normally more efficient than separate visits. We’ll send you a clear quote for the lot.
Why us?
- We never seal over old sealant
- 20+ years of sealant experience
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What we can’t put right
It helps to know what we can’t do too:
- Timber that has rotted
- Damaged stone surrounds
- Sashes that need overhauling
Not sure which it is? You can send an email to info@mrmastic.co.uk and we will tell you honestly.
What we seal
- Timber door frames
- Tenement windows
- Stone surrounds
- Brick reveals
- Period & listed homes
- Sash and case windows
