How we handle sand mastic in Pittswood
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On older homes, it suits the building far better than silicone. Typical jobs include tired mastic found when preparing windows for paint and weathered mastic on the most exposed windows, on period & listed homes, tenement windows and timber door frames.
Homes in small places like Pittswood often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
Whatever the size of the job, you get the same one-year guarantee.

What else we do in Pittswood
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Why it’s worth doing now in Pittswood
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. Where a wall is exposed, as many are in small places like Pittswood, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Call for a quick quote and we will go through it with you.
What you get with us
- Full insurance on every job
- Approved under the ARBOMaster scheme
- We never seal over old sealant
- Anti-fungal sanitary silicone in wet areas

Different surfaces, different methods
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. It’s renewed by hand.
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
How to look after the new joints
Good habits help new joints last longer. A few tips:
- Leave the new mastic unpainted
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
- Find out about consent before window work on a listed home
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.

Frames and glazing around Pittswood
Historic houses like Old Soar Manor (about 2.6 miles north) are a reminder that the area around Pittswood 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Tonbridge station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Do you need sand mastic in Pittswood?
Previous repairs in cement or silicone often trap water or crack away. They don’t move with the timber and we normally remove them.
Any of these means the joints need attention:
- Old cement repairs round a window that have failed
- Mastic dropping out of the joint
- Gaps where the frame meets the masonry
- Wind and rain getting in round a sash window
Schools such as Hadlow Rural Community School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

The process
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. In a small place like Pittswood, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- 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
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
