Pingewood Window Mastic
Mastic around window and door frames, sills and patio doors for homes and businesses in Pingewood and across Reading. Fully insured, ARBOMaster approved and guaranteed for a year.
- Cold air getting in at the frame edge
- White mastic on grey or black frames
- Rain getting in at the frame or under the sill
Keeping the joints in good condition
Aftercare is simple:
- Keep drainage slots and sill grooves clear
- Avoid blasting the frames with a pressure washer
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Dealing with it when you first notice a crack avoids chasing leaks through the wet months.
How we handle window mastic in Pingewood
Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for rain getting in at the frame or under the sill and rushed sealant from a window installation, across aluminium frames, timber windows & doors and window sills.
In a village or hamlet like Pingewood, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, large or small.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. In a small place like Pingewood, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. 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. In a small place like Pingewood, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Pingewood homes and the weather
Historic houses like Mapledurham House (about 4.7 miles north) are a reminder that the area around Pingewood 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. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Rented homes near Reading Green Park 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. For site and facilities teams at buildings such as The WREN School, its window and door frames need their mastic kept sound, just like a home’s.

Common questions in Pingewood
Is Pingewood in your area for window mastic?
Yes. Our work covers London and the South East, and Pingewood is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
I let a flat near Reading Green Park station. Can you help?
Yes. We work for landlords and letting agents as well as householders. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. After that, you can carry on with your day.
Is it OK to seal over old sealant?
No, it will not last. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Can you match the sealant to my frames?
Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.
What should I tell you?
A short description and the location, with photos by email if possible. We will ask anything else we need to know.
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.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.

Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a one-year guarantee.
When to call us in Pingewood
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
Common reasons people contact us are:
- Untidy mastic left by window fitters
- Old mastic that has gone black or come away
- Water coming in at the bottom corners of a door
- A bead that doesn’t match the frame
Mapledurham House, about 4.7 miles north, is one of the historic houses in the wider area around Pingewood, and older homes nearby need a sealant that suits their walls.

Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Timber windows & doors
Soft or rotten wood can’t be sealed successfully. We’ll point out any rot we find, as that is a job for a joiner.
