Wadhurst Window Mastic
Window mastic for Wadhurst, by sealant specialists with 20+ years’ experience. 180+ five-star Google reviews and a 4.9 rating.
- Cracked or shrunken mastic around the frame
- Whistling draughts around closed windows
- Water coming in at the bottom corners of a door
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Make sure the drainage slots are not blocked
- Air rooms to keep condensation down around windows
- Avoid harsh chemicals near the mastic
- Keep jet washers away from the mastic
On timber frames, keep the paintwork in good order, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

Do you need window mastic in Wadhurst?
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.
The problems people generally mention when they call are:
- Gaps left after new windows were fitted
- Rain getting in at the frame or under the sill
- Gaps between the frame and the inside reveal
- Mastic that’s falling out in pieces
If you look after a building such as Wadhurst CofE Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What happens on the day
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and clear up. Most jobs take a few hours for a few frames, or a day or more for a whole house. Parking around Wadhurst is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Clear items away from the joints we’re working on
- Mention any tricky access
- Mention any leaks or damp you’ve noticed

Related advice
What happens if it’s left?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Wadhurst, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, call 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.

Windows and doors in Wadhurst
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. With historic houses such as Wadhurst Castle (about 0.1 miles south) nearby, there’s older building stock in the area around Wadhurst as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.

Homes close to The Parish Church of St Peter and St Paul include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.

Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.

Surface by surface
uPVC windows
The frame is cleaned with a product that won’t harm the plastic, then the sealant goes in between frame and wall.
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.
