Cramhurst homes and the weather
With historic houses such as Loseley Park (about 4.4 miles north-east) nearby, there’s older building stock in the area around Cramhurst as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St John the Evangelist's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How we handle window mastic in Cramhurst
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on window sills, aluminium frames and patio & French doors, and people most often call us about gaps left after new windows were fitted and draughts coming in around windows and doors.
Around Cramhurst, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear any debris from frame drain holes
- Walk round the house once a year and look at the joints
- Air rooms to keep condensation down around windows
- Avoid harsh chemicals near the mastic
Have a look at the joints once a year, ideally after winter. Cracks and lifting edges are easy to spot early.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
Signs you need window mastic in Cramhurst
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
The problems people normally mention when they call are:
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
For landlords with property near Milford (Surrey) station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What else we do in Cramhurst
How it works
The work is kept neat and contained to the area we’re working on. Expect the work to take a morning for a couple of windows and a door. Somewhere as small as Cramhurst, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
