Window & door mastic in New Pound, Kent
Our applicators work in New Pound on mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Rain getting in at the frame or under the sill
- Gaps where the sill meets the wall
- Mastic that’s falling out in pieces
Window mastic in New Pound, done properly
Most frames have an outside joint and an inside one. 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. If you are dealing with black, perished sealant on frames and gaps left after new windows were fitted, we can help.
Mastic can only go onto a dry, clean joint, so window work in New Pound is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
You get a 12-month guarantee, the same in New Pound as everywhere else we work.

What the job involves on each surface
Composite doors
A composite door normally sits in a plastic outer frame, so its perimeter joint is sealed much like a window. The bead is colour-matched to the frame.
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so we pay close attention there.

Why deal with it now?
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. Wait for damp to appear and there may be plaster and decorating to sort out too. Around New Pound, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

What window mastic looks like in New Pound
Historic houses like Old Soar Manor (about 1.9 miles west) are a reminder that the area around New Pound has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Lawrence's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Wateringbury station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Can I do it myself?
If you’re 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 does not work out, we can still put it right.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Common questions in New Pound
Is New Pound in your area for window mastic?
Yes. Our work covers London and the South East, and New Pound is part of that. You can ring 0345 464 0079 or drop us an email and let us know what needs doing.
Will you come out to New Pound?
Yes, New Pound is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you take out the old sealant first?
Yes, every time. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
Will resealing my frames help with draughts?
If the draught is coming in around the frame, yes. If it’s coming through the window seals, we’ll tell you.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
How long does it take to reseal the windows on a house?
A handful of frames is a short visit. You will get a timescale with the quote.
Can I paint over the new sealant?
Silicone generally won’t take paint. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.
When to call us in New Pound
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid can’t flex. That’s what backing rod is for.
People usually contact us after spotting one of these:
- Cracked or shrunken mastic around the frame
- Draughts coming in around windows and doors
- Rain getting in at the frame or under the sill
- Old mastic that has gone black or come away
If you look after a building such as Mereworth Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- How long to leave it before use
- Whether VAT is included
- Whether the sealant suits the joint
- How the colour is chosen
What we cannot put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- A sash or casement that won’t close properly
- A failed sealed unit that has misted up
- Damp problems in the wall away from the window
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly before booking.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a few frames, or a day or more for a whole house, and the area is left clean. Somewhere as small as New Pound, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First we look at every frame and agree the list.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Mention if the joints have been sealed before
- Tell us about access, such as stairs, a lift or high-level joints
- Keep pets and children clear of the area while we work
