- Silicone on a period window that looks wrong

When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Sash cords, weights and draught-proofing of the sashes
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)

Sand mastic in Stroud Green, 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 will talk through which suits your home. We work on period & listed homes, sash and case windows and tenement windows, and people most often call us about gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out.
Somewhere as small as Stroud Green, 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 Stroud Green and across Essex.

What affects the cost of sand mastic
We don’t publish a price list, because no two jobs are the same. What we look at:
- How much there is to do
- Whether there’s mould to deal with
- Working hours on commercial sites
- How many rooms, windows or areas are involved
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.
Helping us quote
Photos by email are helpful but not essential. Please mention:
- The type of property
- What’s wrong with the joints now
- Access, such as stairs, a lift or height
- The address or postcode of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add pictures by email if you can.
Why deal with it now?
Draughts round a sash window aren’t always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Stroud Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

What sand mastic looks like in Stroud Green
With historic houses such as Southchurch Hall (about 3.8 miles south-east) nearby, there’s older building stock in the area around Stroud Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Rochford station, older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like St Teresa's Catholic Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Surface by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
When to call us in Stroud Green
Some old mastic was never deep enough. Mastic that is too thin cracks and drops out, which is why we pack deep voids first and get the depth right.
The most common problems we see are:
- Wind and rain getting in round a sash window
- Window mastic to renew ahead of painting
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
Homes close to Church of St Mary the Virgin include some older properties, and the joint between an old wall and a newer frame is normally the first place rain gets in.
