Window mastic in Puckaster
From a single sill to a whole house of windows, you’ll get a clear quote before any work starts. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. We work on patio & French doors, timber windows & doors and window sills, and people most often call us about whistling draughts around closed windows and a bead that doesn’t match the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Puckaster is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, we protect the area and start. It normally takes a few hours for a handful of frames, longer for a whole house. Somewhere as small as Puckaster, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Keep children and pets away from the work area
- Mention any tricky access

Advice
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Signs you need window mastic in Puckaster
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.
These are the problems we’re asked about most:
- Old mastic that has gone black or come away
- A bead that does not match the frame
- Water coming in at the bottom corners of a door
- Mastic that has split away from the wall
If you look after a building such as Niton Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.
When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Faulty window hardware
- Condensation trapped between the panes
- Soft or decayed wood in the frame
If in doubt, ring 0345 464 0079 or email us and we will say what we think before you book.

What window mastic looks like in Puckaster
Puckaster is close to 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. 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 Church of St. John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

FAQs for Puckaster
Does living near the coast affect window mastic in Puckaster?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are usually the first to need attention.
Do you cover Puckaster for window mastic?
Yes, Puckaster is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job.
Do you work for hotels and businesses?
Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.
Can you seal the gap between the frame and the plaster indoors?
Yes, we do both. Indoors, we seal between the frame and the plaster or reveal, using a paintable sealant if you want to decorate.

The work takes a morning for a couple of windows and a door. Access and how stubborn the old mastic is affect the time most.
Are you insured?
