Sand mastic for homes and businesses in Wester Pencaitland
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 replace one with the other. If you’re dealing with cracked mastic round a front door frame and draughts and rain around sash boxes, we can put it right.
Older stone-built homes in Scotland often have sash and case or timber windows set in stone. Those suit a traditional sand mastic or a neutral-cure sealant, not an acetoxy silicone that can attack some stone.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

How we quote for sand mastic
We quote each job individually. These are the things that affect it:
- Any mould that needs treating
- The type of sealant required
- When we can work, for business premises
- The size of the job
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
What we need to know
When you contact us, it’s useful to know:
- What’s wrong with the joints now
- A few photos by email, if you can
- The address or postcode of the job
- If it’s domestic, commercial or a hotel

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

Your questions about sand mastic in Wester Pencaitland
Do you cover smaller places like Wester Pencaitland?

How long does sand mastic take?
It depends on the size of the job, but as a guide it takes a few hours for a single window, longer for several. We will tell you when we quote.
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.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Can new sealant go over the old?
No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Is sand mastic better than silicone for my windows?
It depends on the window. Period windows in stone or brick generally suit sand mastic and newer frames usually get a flexible sealant.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Avoid heavy scraping on the mastic joint
- Ask a joiner to look at soft timber first
- Clear gutters so water does not pour onto the windows
- Find out about consent before window work on a listed home
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
Why it’s worth doing now in Wester Pencaitland
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. In an older home around Wester Pencaitland, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
