How we handle sand mastic in Fryerning
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on period & listed homes, timber door frames and tenement windows, and the jobs we see most are old sand mastic that has cracked, crumbled or fallen out and modern sealant on a period surround.
Somewhere as small as Fryerning, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Get any rot dealt with first
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
- Do not run silicone over sand mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Common problems we fix in Fryerning
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Common reasons people contact us include:
- Silicone on a period window that looks wrong
- Gaps where the frame meets the masonry
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
If you look after a building such as Ingatestone Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

Fryerning questions
Will you come out to Fryerning?
Yes, Fryerning is covered. Our work covers London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you cover Fryerning for sand mastic?

What is sand mastic?
It’s sand mixed with a linseed-oil-based binder for the joint between timber frames and masonry.
Can landlords and businesses book you?
Yes, we do. We work in homes, commercial premises and hotels, and we are fully insured.
Is sand mastic better than silicone for my windows?
We will help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
Can I paint the new mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Talk to us before any painting near it.
Is consent needed for window work on a listed home?
Checking first is sensible. Your local planning authority can say if consent is needed for listed or conservation-area properties.
How long does the job take?
Most jobs take anything from a few hours to a full day, depending on how many windows, including preparation and clearing up. Your quote will say how long we expect yours to take.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Surface by surface
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We can do one window or several.
How it works
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before work begins. The work usually takes a few hours per window, depending on the condition of the joints. Somewhere as small as Fryerning, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check the window surrounds and agree which joints need renewing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area

Windows and doors in Fryerning
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. Historic houses like Ingatestone Hall (about 1.4 miles south-east) are a reminder that the area around Fryerning has older buildings as well as new. 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.
For landlords with property near Ingatestone station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you live in an older home near Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.
