Patrixbourne Window Mastic
Mastic around window and door frames, sills and patio doors for householders, landlords and businesses in Patrixbourne. Fully insured, ARBOMaster approved and guaranteed for a year.
- Hard, cracked sealant around windows
- Black, perished sealant on frames
- Gaps between the frame and the inside reveal
Window mastic in Patrixbourne
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. We seal one or both, depending on what’s needed. Typical jobs include white mastic on grey or black frames and gaps left after new windows were fitted, across window sills, uPVC windows and timber windows & doors.
Somewhere as small as Patrixbourne, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What we cannot put right
We will not take on work that will not last, so these are the limits:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
- A sash or casement that won’t close properly
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Check the mastic once a year
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Use gentle cleaners on frames and sealant
Wipe the frames with soapy water when you clean the windows, and avoid solvent cleaners on the sealant.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
Patrixbourne homes and the weather
Historic houses like Goodnestone Park (about 4 miles east) are a reminder that the area around Patrixbourne has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Bekesbourne station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as Bridge and Patrixbourne Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

When to call us in Patrixbourne
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
The problems people usually mention when they call are:
- Rain getting in at the frame or under the sill
- Draughts coming in around windows and doors
- Leaking joints at the ends of sills
- Mastic that has split away from the wall
In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

We bring everything the job needs with us, so you do not need to buy or prepare anything. 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. For a village or hamlet like Patrixbourne, the journey is planned in advance: let us know about lanes, gates and parking. 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.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
