How we handle sand mastic in Hastingwood
Across Hastingwood, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. Common call-outs are for silicone on a period window that looks wrong and old cement repairs round a window that have failed, across period & listed homes, timber door frames and sash and case windows.
Outdoor sealant needs dry, clean surfaces, so work on frames around Hastingwood is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Clear gutters so water doesn’t pour onto the windows
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
- Keep modern sealant off the mastic
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
When it is not the sealant
Before booking, it’s worth knowing the limits too:
- Putty and glazing repairs
- Masonry that needs repairing
- Sashes that rattle, stick or won’t open
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before you book.

Hastingwood homes and the weather
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.
Homes close to Church of St Mary Magdalene include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you look after a building such as Henry Moore Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Common problems we fix in Hastingwood
Timber swells and shrinks with the weather. The movement cracks the mastic over time.
Common reasons people contact us are:
- A silicone bead on a sash window that spoils the look
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
- Weathered mastic on the most exposed windows
If you let a flat or house near Harlow Mill station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

What happens on the day
There is not much for you to do on the day. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several, including the tidy-up. In a small place like Hastingwood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know about stairs, lifts or work at height
- For business premises, tell us about site rules or sign-in
- Tell us if parking is tricky
