Window & door mastic in Broughton, Hampshire
Window mastic in Broughton from a team with over 20 years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Leaking joints at the ends of sills
- A bead that doesn’t match the frame
- Draughty joints inside around the window
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Wash the frames with mild soapy water
- Ventilate rooms so frames don’t stay wet inside
- Walk round the house once a year and look at the joints
- Keep drainage slots and sill grooves clear
Try not to touch the new joint while it cures, following the cure time we give you. Keep jet washers away from the frames.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Window mastic in Broughton
The new joint does not have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. Typical jobs include cracked internal joints between frame and plaster and white mastic on grey or black frames, across composite doors, aluminium frames and patio & French doors.
Somewhere as small as Broughton, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

How the job changes by surface
Composite doors
A composite door usually sits in a plastic outer frame, so its perimeter joint is sealed much like a window. We match the colour to the frame.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Why deal with it now?
Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, using a product chosen for the frame and wall. Older cottages and farmhouses around Broughton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and give you a clear price before work begins.

Honest limits
We will not take on work that won’t last, so here’s what sealant can’t put right:
- Condensation trapped between the panes
- Damp problems in the wall away from the window
- A frame that has rotted at the joint

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Window mastic in Broughton: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Mottisfont Abbey (about 3.9 miles south) are a reminder that the area around Broughton has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in. Rented homes near Mottisfont & Dunbridge station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Broughton Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.
