How the visit works
The work is kept neat and contained to the area we’re working on. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. Outdoor work around Glenbrook depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Work indoors is not affected.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Preparing for the visit
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- On commercial sites, let us know about site rules

Advice
Sand mastic in Glenbrook
Sand mastic suits most period window surrounds. Newer frames generally get a flexible sealant instead, and we will talk through which suits your home. We work on brick reveals, timber door frames and period & listed homes, and people most often call us about old cement repairs round a window that have failed and failed mastic on an exposed elevation.
In and around a place like Glenbrook, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.
The work is covered for a year after we finish. If anything isn’t right with it, email us at info@mrmastic.co.uk.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
Glenbrook questions

Which products do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We explain the product when we quote.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
Are you insured?
Yes. Full insurance covers our work.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
Windows and doors in Glenbrook
The Old and New Towns of Edinburgh are a UNESCO World Heritage Site, and the Georgian New Town is known for its sash windows. For listed homes and conservation areas, check with the council before changing how windows or walls look. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.
For site and facilities teams at buildings such as Balerno Community High School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Curriehill station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. Our tips:
- Have rotten timber repaired before new mastic goes in
- Go gently near the mastic when preparing windows
- Check the mastic when you check the paintwork
- Make sure water runs off the sill
Leave the new mastic unpainted, which is the traditional advice. Ask us before any decorating around it.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

Why it’s worth doing now in Glenbrook
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Exposed walls in smaller Scottish places take a lot of wind and rain, 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 usually makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

When to call us in Glenbrook

People normally contact us after spotting something like this:
- Failed mastic on an exposed elevation
- Draughts and rain around sash boxes
- Crumbling sand mastic round a window
- Tired mastic found when preparing windows for paint
Homes close to Balerno Parish Church include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
