Frames and glazing around Hinxhill
With historic houses such as Godinton House (about 4.3 miles west) nearby, there’s older building stock in the area around Hinxhill 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. 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.
If you look after a building such as Brook Community Primary School, its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How we handle window mastic in Hinxhill
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you’re dealing with cracked or shrunken mastic around the frame and old mastic that has gone black or come away, we can help.
Somewhere as small as Hinxhill, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
You get a one-year guarantee, the same in Hinxhill as everywhere else we work.

Looking after it afterwards
A little care helps the new joints last. We recommend:
- Do not aim a pressure washer at the joints
- Look round the frames every year or so
- Do not use solvent cleaners on the joint
- Repaint timber before it’s bare
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or send us an email.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Should I try it myself first?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
What the job involves on each surface
Window sills
Every drop off the glass ends up on the sill, so the sill ends and the joint under the frame are vital. They’re cut out and resealed with exterior sealant.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
What happens if it’s left?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Older cottages and farmhouses around Hinxhill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.

Questions from Hinxhill
Can you do window mastic in Hinxhill?
Yes. Our work covers London and the South East, and Hinxhill is part of that. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Can you help a landlord with a rental near Ashford International station?
Yes. We work for letting agents and landlords as well as householders. You can phone 0345 464 0079 or drop us an email with the details for a clear quote.
Can you do the inside joint as well?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Can I paint over the new sealant?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Mention any painting plans before work begins.
Can you seal over the old sealant?
No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. We remove it all first.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Do you hold any approvals?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you reach windows above the ground floor?
Yes, in most cases. We plan safe access before the job.
When to call us in Hinxhill
Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.
Signs it’s time to call us include:
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- A bead that does not match the frame
Rented homes near Ashford International 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.

How the visit works
You don’t need to clear the whole room or building before we come, only the area right around the joints. Everything nearby is protected, and the job takes most of a day for a typical house, less for a few frames for a typical job. In a small place like Hinxhill, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- 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.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- On commercial sites, let us know about site rules
- Move anything stored near the joints
- Keep children and pets away from the work area
