Staplestreet Window Mastic
Our applicators work in Staplestreet on mastic around window and door frames, sills and patio doors. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Hard, cracked sealant around windows
- A bead that does not match the frame
- Cracked internal joints between frame and plaster
Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Keep timber frames painted
- Look round the frames every year or so
- Paint up to the joint, not over it
- Air rooms to keep condensation down around windows
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
Window mastic in Staplestreet
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on patio & French doors, composite doors and uPVC windows, and common reasons people get in touch are rain getting in at the frame or under the sill and cracked sealant at the sill ends.
Somewhere as small as Staplestreet, 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.
A one-year guarantee comes as standard, so you are covered after we have gone.

How the job changes by surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Signs you need window mastic in Staplestreet
Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.
People usually contact us when they notice one of these:
- Cracked internal joints between frame and plaster
- Whistling draughts around closed windows
- White mastic on grey or black frames
- Water coming in at the bottom corners of a door
If you look after a building such as Boughton-under-Blean and Dunkirk Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Why act early in Staplestreet
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Staplestreet, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

The process
Once we are on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Staplestreet, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property
- Clear items away from the joints we’re working on

Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Selling station? Then renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Church of St Michael, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
