How we handle window mastic in Bridge
Frames and walls don’t move together. Heat and cold make frames grow and shrink against brick or render that hardly moves. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have black, perished sealant on frames and draughty joints inside around the window, we can put it right, on uPVC windows, patio & French doors and aluminium frames alike.
Mastic can only go onto a dry, clean joint, so window work in Bridge is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
We stand behind the work with a one-year guarantee, so you are covered after we’ve gone.

Why act early in Bridge
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Around Bridge, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Why Bridge customers choose us
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over
- Sanitary silicone with an anti-fungal additive in wet areas
- ARBOMaster approved applicator

What window mastic looks like in Bridge
With historic houses such as Goodnestone Park (about 4.4 miles east) nearby, there’s older building stock in the area around Bridge as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
In the older streets around Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Bekesbourne station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Advice
FAQs for Bridge
I let a flat near Bekesbourne station. Can you help?
Yes. We work for landlords and letting agents as well as householders. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear price.
Do you cover smaller places like Bridge?
Yes, Bridge is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
Can new window sealant be painted?
Not generally, if it’s silicone. We choose the product with your decorating in mind, so mention it when you book.
Can you get sealant to suit coloured frames?
Yes. Grey and black frames get grey or black sealant, and wood-effect frames normally suit brown.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Where are you based?
We work from Crawley. We cover Bridge and the rest of Kent.
Are you fully insured?
Yes. We’re fully insured for every job we do.
How to look after the new joints
So the new joints stay in good condition:
- Look round the frames every year or so
- Clear any debris from frame drain holes
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

Signs you need window mastic in Bridge
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. A sealant that can’t keep up eventually tears.
These are the problems we’re asked about most:
- Hard, cracked sealant around windows
- Cracked internal joints between frame and plaster
- A bead that doesn’t match the frame
- Untidy mastic left by window fitters
If you look after a building such as Bridge and Patrixbourne Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What to look for in a quote
- What the cure time is
- How long the guarantee is
- How the colour is chosen
- Whether the sealant suits the joint

Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
Timber moves with moisture as well as heat, so a flexible sealant is essential. We seal onto sound, dry paintwork or timber.
