DIY sealant or a professional job?
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, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sand mastic in Magdalen Laver, done properly
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes, where modern sealant can look out of place. Typical jobs include mastic dropping out of the joint and mastic that needs renewing before redecorating, across brick reveals, sash and case windows and period & listed homes.
Around Magdalen Laver, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

Your questions about sand mastic in Magdalen Laver
Is Magdalen Laver within the area you cover?
Yes, Magdalen Laver is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Harlow Mill station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.
What does sand mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
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. Larger jobs naturally take longer, and we’ll say how long yours will take.
Is it OK to seal over old sealant?
No, it won’t last. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we are using.
Can old silicone round a sash window be swapped for sand mastic?
Yes, it’s a common request. The old silicone has to come out completely so the mastic beds in well.
How we quote for sand mastic
We don’t publish a price list. The quote depends on:
- Whether there’s mould to deal with
- Whether the work is at height
- The number of rooms or windows
- The old material and how stubborn it is
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
What to tell us for a quote
You do not need to know the technical terms. It helps if you can tell us:
- If someone has resealed it before
- The rough size of the job
- Access, such as stairs, a lift or height
- A few photos by email, if you can

Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.
