Frames and glazing around Parkhouse
Historic houses like Pollok House (about 2.2 miles north-east) are a reminder that the area around Parkhouse has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Much of Glasgow is built from red and blond sandstone, and porous sandstone needs a sealant that won’t mark it.
For landlords with property near Nitshill station, older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Barrhead High School, larger buildings have plenty of frames, and the mastic around each one ages.
Parkhouse is about 1 mile east of Barrhead, in Glasgow. We carry out sand mastic for householders, landlords and businesses in Parkhouse and the surrounding area, as part of our work across Glasgow. Our area takes in 183 places across Glasgow.

How we handle sand mastic in Parkhouse
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include weathered mastic on the most exposed windows and silicone on a period window that looks wrong, on stone surrounds, timber door frames and sash and case windows.
Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. For a flat in Parkhouse, access is the first thing to plan.
You are covered for a year from the day we finish. If there’s a problem with it, please send an email to info@mrmastic.co.uk.

Parkhouse: your questions answered
Is Parkhouse in your area for sand mastic?
Yes, Parkhouse is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.
Who arranges sealant work on the shared parts of a tenement in Parkhouse?
It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds do not.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is sand mastic better than silicone for my windows?
That depends on your windows. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and you’ll get one quote.
Will there be a smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.
When to call us in Parkhouse
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber, and they normally need raking out.
Look out for any of the following:
- Old cement repairs round a window that have failed
- Wind and rain getting in round a sash window
- A silicone bead on a sash window that spoils the look
- Mastic that needs renewing before redecorating
Historic houses such as Pollok House, about 2.2 miles north-east, show how far back building around Parkhouse goes.

How it works
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints. In a city area like Parkhouse, parking may be by permit or pay-and-display, so tell us what’s nearby. If you are in a flat, let us know how we get in at the street door.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep pets and children clear of the area while we work
- Let us know if you’ve seen damp or leaks

Should I try it myself first?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.

When it isn’t the sealant
To be straight with you, there are a few things sealant won’t fix:
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
- Putty and glazing repairs
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before booking.
Surfaces we seal
- Stone surrounds
- Tenement windows
- Brick reveals
- Timber door frames
- Period & listed homes
- Sash and case windows
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Avoid patching sand mastic with silicone
- Find out about consent before window work on a listed home
Do not run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
