Sand mastic in Wincheap
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. If you are dealing with failed mastic on an exposed elevation and tired mastic found when preparing windows for paint, we can help, on sash and case windows, period & listed homes and timber door frames alike.
Houses in smaller places like Wincheap can stand more in the open than those in a built-up town. That is hard on the mastic around frames and sills.

How the visit works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. For a job in Wincheap, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Try not to wet indoor joints just before the visit
- Plan for the work area to be out of bounds to pets and children
- For business premises, tell us about site rules or sign-in

Frames and glazing around Wincheap
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Wincheap Foundation Primary School? Then the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Church of St Mildred, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Quotes for sand mastic in Wincheap
Your quote is based on your job. We look at:
- The type of sealant required
- Working hours on commercial sites
- Whether there’s mould to deal with
- The size of the job
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- The type of property
- How many joints, rooms or windows are involved
- Where the property is
- The problem you’ve noticed
Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job, and pictures are welcome.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Decayed frames that need repair
- Sashes that rattle, stick or won’t open
- Masonry that needs repairing
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.
Surfaces we seal
- Stone surrounds
- Timber door frames
- Period & listed homes
- Brick reveals
- Tenement windows
- Sash and case windows
Different surfaces, different methods
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Timber door frames
Doors face weather and wear, so their mastic can fail sooner. It’s renewed by hand.
Aftercare tips
After the cure time, these simple habits help:
- Go gently near the mastic when preparing windows
- Leave the new mastic unpainted
- Get any rot dealt with first
- Clear gutters so water does not pour onto the windows
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
Why it’s worth doing now in Wincheap
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around Wincheap, damp from a failed joint can get into timber and plaster, and that is a much bigger job than renewing the sealant.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
