Sand mastic in Deans, done properly
Sand mastic suits most period window surrounds. On modern frames we’d normally use a flexible sealant, and we will talk through which suits your home. If you’re dealing with mastic round period door frames that has failed and mastic worn away on windows facing the weather, we can put it right, whatever the surface.
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.
Your job is guaranteed for a year, as with all our work.

What we need to know
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

- Photos by email, if that is easy
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll talk you through the work before giving you a price.
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. The longer it’s left, the more the joint opens.

How long will you be here?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we will tell you how long to expect.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Can sand mastic be painted?
Traditional guidance is not to paint over sand mastic. Ask us before you decorate around it and we will advise.
Do you need sand mastic in Deans?
Scraping and sanding before painting can loosen old mastic. Many people find it crumbling when they prepare the windows, which is a good time to renew it.
These are the problems we’re asked about most:
- Tired mastic found when preparing windows for paint
- Mastic round period door frames that has failed
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
Rented homes near Livingston North station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Deans homes and the weather

With historic houses such as Howden House (about 1.5 miles south-east) nearby, there’s older building stock in the area around Deans as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first.
