Specialist sand mastic for Covington: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Mastic dropping out of the joint
How to look after the new joints
To keep the joints looking good and working properly:
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
About our sand mastic in Covington
Across Covington, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand for a neat, traditional finish. Common call-outs are for cracked mastic round a front door frame and mastic worn away on windows facing the weather, on brick reveals, sash and case windows and timber door frames.
Outdoor sealant needs a dry surface, so window work around Covington is planned around the weather. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If something is not right with it in that time, tell us and we’ll put it right.

FAQs for Covington
I let a flat near Carstairs station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Do you cover Covington for sand mastic?
Yes. Our work covers the whole of Scotland, and Covington is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic beds in well.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Can I choose the sealant colour?
Most of the time, yes. We will tell you which colours the right product comes in and agree one before any work starts.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish but the decision is theirs.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic, while modern frames normally get a flexible sealant.
How the job changes by surface
Sash and case windows
Most of our sand mastic work is on sash windows. Each joint round the box is raked out and renewed.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Can I do it myself?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What we’re called out for in Covington
Previous repairs in cement or silicone often trap water or crack away. They do not move with the timber and we normally remove them.
If you can see any of these, it’s time to have the joints looked at:
- Draughty sash windows at the surround
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Weathered mastic on the most exposed windows
Homes close to Covington Parish Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Is the old sealant removed completely?
- Who turns up on the day
- What product goes in the joint
- What the cure time is
What happens if it’s left?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water behind a failed seal does the most damage when nobody’s watching.
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. Call for a quick quote and we will explain what it covers.
What you get with us
- Experience in homes, commercial sites and hotels
- We never seal over old sealant
- Tidy, careful work
- An ARBOMaster approved applicator

Covington homes and the weather
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with 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.
For landlords with property near Carstairs station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

The process
When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours per window, depending on the condition of the joints. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.
- First, we look at the surrounds with you and agree what needs doing.
- 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.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
