Window mastic in Broad Tenterden, done properly
Mr Mastic’s applicators have more than 20 years’ experience with window and door sealants. We’re fully insured ARBOMaster approved applicators, and we give a one-year guarantee on the work. If you’re dealing with cracked sealant at the sill ends and white mastic on grey or black frames, we can put it right, on aluminium frames, uPVC windows and window sills alike.
Homes in small places like Broad Tenterden often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
All our work is covered by a 12-month guarantee.

Honest limits
In fairness, there are a few things sealant will not fix:
- Penetrating damp from a failed cavity tray or render
- A frame that has rotted at the joint
- Condensation trapped between the panes
If in doubt, ring 0345 464 0079 or email us and we will say what we think.

Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
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.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
- Clear any debris from frame drain holes
- Ventilate rooms so frames don’t stay wet inside
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at 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. Resealing closes it.

Leave it or put it right?
Not every sealant suits a window. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Where a wall is exposed, as many are in small places like Broad Tenterden, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

Window mastic in Broad Tenterden: local notes
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. With historic houses such as Smallhythe Place (about 1.6 miles south) nearby, there’s older building stock in the area around Broad Tenterden 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.
If you live in an older home near Parish Church of St Mildred, the joint between an old wall and a newer frame is normally the first place rain gets in. Managing a site like Tenterden Church of England Junior School? Then its window and door frames need their mastic kept sound, just like a home’s.
