Common questions in Redhall
Can you help a landlord with a rental near Kingsknowe station?
Yes, rental work is part of what we do. You can send an email to info@mrmastic.co.uk with the address and a few details, and we’ll give you a fixed price before we start.
Can you do sand mastic in Redhall?
Yes, Redhall is within the area we cover. Our work covers the whole of Scotland. Just send an email to info@mrmastic.co.uk with a few details of the job, and we will give you a clear price.
Which is right for my windows, sand mastic or modern sealant?
It depends on the window. On many period windows, sand mastic looks right and suits the building and newer frames usually get a flexible sealant.
Can you replace silicone on a period window with sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic can sit properly.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we will tell you what to expect.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Do you take out the old sealant first?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Sand mastic for homes and businesses in Redhall
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. We work on period & listed homes, timber door frames and stone surrounds, and people most often call us about gaps where the frame meets the masonry and failed mastic on an exposed elevation.
Tenement flats in Scotland’s cities often have windows high above the street, where failing mastic is easy to miss. For a flat in Redhall, access is the first thing to plan.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Frames and glazing around Redhall
Historic houses like Whitefoord House (about 3.7 miles north-east) are a reminder that the area around Redhall has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Who owns the windows depends on the title deeds.
Schools such as Merchiston Castle School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Whitefoord House, about 3.7 miles north-east, is one of the historic houses in the wider area around Redhall, and older homes nearby need a sealant that suits their walls. If you let a flat or house near Kingsknowe station, any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
A careful DIYer can reseal a simple joint, 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.
A DIY attempt does not rule out a professional job. We cut it out and start again.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. Scottish rain finds any gap around a frame or wall joint, and in a tall building in Redhall, damp can travel a long way before it shows.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we will go through it with you.

Different surfaces, different methods
Tenement and terrace windows
Windows above ground floor need the right access. Tell us the height and we will confirm what’s needed.
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows, and the area is left clean.
