How we handle window mastic in Sandhurst Cross
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. We work on composite doors, window sills and uPVC windows, and common reasons people get in touch are leaking joints at the ends of sills and damp patches on the reveal after heavy rain.
Outdoor sealant needs dry, clean surfaces, so work on frames around Sandhurst Cross is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Can I do it myself?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Landlord and commercial work in Sandhurst Cross
Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.
Common problems we fix in Sandhurst Cross
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Draughty joints inside around the window
- Gaps left after new windows were fitted
- Sealant in the wrong colour for the frame
- Old mastic that has gone black or come away
Homes close to Church of St Nicholas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
After the cure time, these simple habits help:
- Make sure the drainage slots are not blocked
- Don’t aim a pressure washer at the joints
- Do not paint over the silicone
- Don’t use solvent cleaners on the joint
Most silicone sealants will not take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
What window mastic looks like in Sandhurst Cross
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Great Dixter (about 2.5 miles south-east) are a reminder that the area around Sandhurst Cross has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you look after a building such as Sandhurst Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Robertsbridge station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
