Window mastic for homes and businesses in Ladwell
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. The sealant then grips the two sides it should. We work on aluminium frames, composite doors and window sills, and the jobs we see most are gaps left after new windows were fitted and cracked or shrunken mastic around the frame.
Around Ladwell, 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.
Big or small, it’s backed by our one-year guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Keep paint off silicone joints
- Keep paint and stain on wooden frames in good order
- Don’t use solvent cleaners on the joint
- Ventilate rooms so frames do not stay wet inside
Most silicone sealants won’t take paint, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
When something else is needed
We will always be straight with you, so here’s what sealant cannot fix:
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
- A sash or casement that won’t close properly
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.

How the visit works
Most of a good job is in the preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a morning for a couple of windows and a door. Somewhere as small as Ladwell, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Frames and glazing around Ladwell
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Chandlers Ford station, renewing tired window mastic between tenants heads off draught and damp complaints. If you look after a building such as John Keble Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Questions from Ladwell
Can you do window mastic in Ladwell?
Yes. Our work covers London and the South East, and Ladwell is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Will you come out to Ladwell?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.
How long will my window job take?
That depends on the number of frames, how they’re reached and the state of the old mastic. We’ll tell you how long your job needs when we quote.
Will you leave a mess?
We keep the work tidy. Nearby surfaces are protected.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
Will resealing my frames help with draughts?
Yes, if the air is getting in around the frame. If it’s through the window’s own seals or a hinge, that is a different fix, and we will say so.
Where are you based?
We’re a Crawley-based firm. We work across South East England, London and Scotland.
What we’re called out for in Ladwell
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. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Gaps between the frame and the inside reveal
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Leaking joints at the ends of sills
In the older streets around Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
