How to look after the new joints
Looking after new joints is easy:
- Ventilate rooms so frames don’t stay wet inside
- Do not paint over the silicone
- Walk round the house once a year and look at the joints
- Clean frames with a soft cloth and soapy water
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The visit itself generally takes a few hours for a handful of frames, longer for a whole house, depending on the size of the job. Somewhere like Little Conghurst needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
How to prepare
- Let us know about stairs, lifts or work at height
- Keep children and pets away from the work area
- Move anything stored near the joints

What happens if it’s left?
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Little Conghurst can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

Signs you need window mastic in Little Conghurst
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
Signs it’s time to call us include:
- Leaking joints at the ends of sills
- Rain getting in at the frame or under the sill
- Black, perished sealant on frames
- Hard, cracked sealant around windows
Rented homes near Etchingham station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Windows and doors in Little Conghurst
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Great Dixter (about 3.9 miles south-east) are a reminder that the area around Little Conghurst has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Hawkhurst Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in.

Different surfaces, different methods
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. We match white, brown, anthracite grey and black frames.
Patio & French doors
Water at the foot of a door frame is not always the mastic: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We look for the cause first.
