Window & door mastic in Goodnestone, Kent
Window and door frames in Goodnestone need attention? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.
- Cracked sealant at the sill ends
- Old mastic that has gone black or come away
- A bead that doesn’t match the frame
What we are called out for in Goodnestone
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
If you can see any of these, it’s time to have the joints looked at:
- Cracked internal joints between frame and plaster
- Water coming in at the bottom corners of a door
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
In the older streets around St Bartholomew's Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

Window mastic in Goodnestone, done properly
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. If the draught is through the window seals instead, we will tell you. We work on aluminium frames, window sills and timber windows & doors, and the jobs we see most are old mastic that has gone black or come away and damp patches on the reveal after heavy rain.
In a village or hamlet like Goodnestone, 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.
Each job carries a 12-month guarantee.

What we do, step by step
All our tools and materials come with us in the van. After a quick look at the joints together, 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 Goodnestone, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Clear items away from the joints we are working on
- On commercial sites, let us know about site rules
- For indoor joints, keep the area dry beforehand if you can

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Work for landlords, hotels and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Landlords and letting agents in Goodnestone can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Frames and glazing around Goodnestone
Goodnestone 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 is hard on the mastic around window and door frames, especially on the side facing the sea. With historic houses such as Belmont House and Gardens (about 5 miles south-west) nearby, there’s older building stock in the area around Goodnestone as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Graveney Primary School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Faversham station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Why deal with it now?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Older cottages and farmhouses around Goodnestone can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What you pay reflects the work, not a rough estimate. That is why we ask a few questions first and agree the price before starting.

- Misting between the panes of a double-glazed unit (that needs a new unit)
