How the visit works
At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours per window, depending on the condition of the joints, depending on the size of the job. For a job in New Alresford, 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 look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

About our sand mastic in New Alresford
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. We work on stone surrounds, brick reveals and tenement windows, and people most often call us about weathered mastic on the most exposed windows and modern sealant on a period surround.
Around New Alresford, conservatories, garden rooms and patio doors are often part of the house. Those joints need the same attention as the main windows.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Surface by surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. The gap round it is pointed with sand mastic.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Leave it or put it right?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad and new mastic seals them. In a smaller place like New Alresford, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.

Signs you need sand mastic in New Alresford
Rain on the window surround works into any crack and pushes it out. Exposed elevations generally fail first.
These are the problems we’re asked about most:
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- Failed mastic on an exposed elevation
If you look after a building such as Sun Hill Junior School, its window and door frames need their mastic kept sound, just like a home’s.

Sand mastic in New Alresford: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hinton Ampner House (about 3 miles south) are a reminder that the area around New Alresford 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.
In the older streets around Church of St John the Baptist, the joint between an old wall and a newer frame is usually the first place rain gets in.
