How we handle window mastic in Pratling Street
Over two decades of sealing frames has taught us which products suit which walls. We’re ARBOMaster approved and fully insured, and we give a one-year guarantee on the work. We work on uPVC windows, patio & French doors and aluminium frames, and common reasons people get in touch are old mastic that has gone black or come away and leaking joints at the ends of sills.
Around Pratling Street, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
All of our work is guaranteed for twelve months, in Pratling Street and everywhere else we cover.

Keeping the joints in good condition
Looking after new joints is easy:
- Avoid blasting the frames with a pressure washer
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Clean frames with a soft cloth and soapy water
Silicone can’t normally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What we do, step by step
When we arrive, we look over the joints with you first, so you know exactly what we are doing. Surfaces next to the work are protected before any work begins. Most jobs take most of a day for a typical house, less for a few frames. Somewhere like Pratling Street needs a little journey planning: 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 how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints

Advice
Also in Pratling Street
Surface by surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What window mastic looks like in Pratling Street
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Starkey Castle (about 4.3 miles north) nearby, there’s older building stock in the area around Pratling Street as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Methodist Church Including Sunday School, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Letting a property close to Aylesford station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. Managing a site like St Peter's Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.

What happens if it’s left?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Around Pratling Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email for an honest opinion and a quote.
