Window Mastic in Chuck Hatch
Mastic around window and door frames, sills and patio doors in Chuck Hatch, with a 12-month guarantee on every job. Call for a quick quote.
- White mastic on grey or black frames
- Cold air getting in at the frame edge
- Leaking joints at the ends of sills
Looking after it afterwards
Looking after new joints is easy:
- Use gentle cleaners on frames and sealant
- Keep drainage slots and sill grooves clear
- Keep timber frames painted
- 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, and if anything looks wrong, just ring 0345 464 0079 or drop us an email.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and heat escapes around the frame. Resealing closes it.
How we handle window mastic in Chuck Hatch
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. Typical jobs include cold air getting in at the frame edge and sealant in the wrong colour for the frame, across patio & French doors, uPVC windows and composite doors.
Somewhere as small as Chuck Hatch, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or send us an email.

What else we do in Chuck Hatch
The process
Every visit runs the same way: we look at the joints together, protect the area around them, do the work and tidy away. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Chuck Hatch needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Keep children and pets away from the work area
- Clear items away from the joints we are working on
- For indoor joints, keep the area dry beforehand if you can

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Aluminium frames
Coated aluminium needs a compatible sealant and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. We seal those with a sealant suited to masonry.
Common problems we fix in Chuck Hatch
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Common reasons people contact us are:
- Rain getting in at the frame or under the sill
- Cracked sealant at the sill ends
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
For landlords with property near Ashurst Kent station, renewing tired window mastic between tenants heads off draught and damp complaints.

Why deal with it now?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. A low-modulus exterior sealant keeps its stretch through hot and cold weather. Around Chuck Hatch, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. You will know the price before we begin.

Window mastic in Chuck Hatch: local notes
With historic houses such as Bassetts Manor (about 2.9 miles north) nearby, there’s older building stock in the area around Chuck Hatch 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.
