Window mastic in Upton, done properly
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. The sealant then grips the two sides it should. We work on aluminium frames, timber windows & doors and uPVC windows, and the jobs we see most are gaps where the sill meets the wall and gaps left after new windows were fitted.
In a village or hamlet like Upton, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
We work for landlords and letting agents as well as homeowners. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.
What we can’t put right
We’d rather tell you now than do work that will not last, so these are the limits:
- Soft or decayed wood in the frame
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Worn gaskets, brush seals or a door that has dropped
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Window mastic in Upton: local notes
Upton is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s hard on the mastic around window and door frames, especially on the side facing the sea. Historic houses like Nunwell House (about 2.2 miles south-east) are a reminder that the area around Upton has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as Church of St. Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Haylands Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

Do you need window mastic in Upton?
Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Most people get in touch after spotting one of these:
- Leaking joints at the ends of sills
- Untidy mastic left by window fitters
- White mastic on grey or black frames
- Gaps between the frame and the inside reveal
For landlords with property near Smallbrook Junction station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
Before booking anyone
- What guarantee comes with the work
- How long to leave it before use
- What product goes in the joint
- Whether they’re fully insured
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Check the mastic once a year
- Keep paint and stain on wooden frames in good order
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Leave it or put it right?
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Where a wall is exposed, as many are in small places like Upton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
