Sand mastic for sash & case windows in Hambledon, Hampshire
Problem with your window and door surrounds in Hambledon? We remove the old material, prepare the joints and seal them properly, with a one-year guarantee.
- Old cement repairs round a window that have failed
- Wind and rain getting in round a sash window
- Mastic that needs renewing before redecorating
Why it’s worth doing now in Hambledon
New sash windows are a major, costly change and on a listed home, consent may be needed. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Older cottages and farmhouses around Hambledon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not guesswork. That is why we ask about the job first and agree the price before starting.
Why book with us
- We are fully insured
- An ARBOMaster approved applicator
- Anti-fungal sanitary silicone in wet areas
- More than 20 years in sealant work

Sand mastic in Hambledon
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on period & listed homes, timber door frames and stone surrounds, and people most often call us about cement or filler used on old window joints that has cracked and silicone on a period window that looks wrong.
Somewhere as small as Hambledon, 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 one-year guarantee comes as standard, so you are covered after we’ve gone.

Aftercare tips
After the cure time, these simple habits help:
- Plan mastic work ahead of painting
- Check the mastic when you check the paintwork
- Leave the new mastic unpainted
- Don’t run silicone over sand mastic
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.

Homes close to Church of St Peter and St Paul include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

That depends on how much there is to do, but most jobs take a few hours for a single window, longer for several. We’ll tell you when we quote.
Is it OK to seal over old sealant?

What we are called out for in Hambledon
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
Most people get in touch after spotting something like this:
- Draughty sash windows at the surround
- Gaps between timber frames and stone or brick
- Mastic dropping out of the joint
- Mastic worn away on windows facing the weather
For site and facilities teams at buildings such as Hambledon Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
