Sand mastic in Teynham Street, done properly
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant and we’ll explain which is best for yours. We are often asked to deal with mastic that needs renewing before redecorating and mastic dropping out of the joint, on timber door frames, period & listed homes and sash and case windows.
Somewhere as small as Teynham Street, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, it’s backed by our one-year guarantee in Teynham Street and across Kent.

What we can’t put right
New sealant cannot fix everything, and we will tell you before work begins. It won’t solve:
- Whether work needs listed building consent
- Crumbling stone or brickwork round the window
- Broken panes
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.

Signs you need sand mastic in Teynham Street
Shallow joints are a common cause. A thin layer doesn’t hold well so we make sure the new mastic is the right thickness.
If you can see any of these, it’s time to have the joints looked at:
- Open joints round the window box
- Silicone on a period window that looks wrong
- Cracked mastic round a front door frame
- Tired mastic found when preparing windows for paint
For an older house near a landmark such as Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in.

What sand mastic looks like in Teynham Street
Teynham Street is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. With historic houses such as Belmont House and Gardens (about 4.8 miles south) nearby, there’s older building stock in the area around Teynham Street 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 is traditional sand mastic.
Letting a property close to Teynham station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Managing a site like Teynham Parochial Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Keeping the joints in good condition
Simple care keeps the joints in good condition. Our advice:
- Check the mastic when you check the paintwork
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Don’t run silicone over sand mastic
Do not touch or press the mastic while it hardens. It forms a skin fairly soon, but takes longer to harden fully.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Different surfaces, different methods
