How we handle window mastic in Lower Bush
Homes in Lower Bush have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. If you’re dealing with white mastic on grey or black frames and mastic that has split away from the wall, we can help.
In a village or hamlet like Lower Bush, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
Big or small, you get the same 12-month guarantee.

Should I try it myself first?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Different surfaces, different methods
Composite doors
Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
What happens on the day
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. For a village or hamlet like Lower Bush, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
How to prepare
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about stairs, lifts or work at height

When to call us in Lower Bush
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
People usually contact us when they notice something like this:
- Leaking joints at the ends of sills
- Cold air getting in at the frame edge
- Gaps left after new windows were fitted
- Gaps between the frame and the inside reveal
Homes close to Church of St Michael and All Angels include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Questions from Lower Bush
Can you do window mastic in Lower Bush?
Yes. We work across London and the South East, and Lower Bush is part of that. You can phone 0345 464 0079 or send us an email and let us know what needs doing, and we’ll send you a clear quote.
Can you help a landlord with a rental near Cuxton station?
Yes. We work for landlords and letting agents as well as homeowners. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll give you a clear quote.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Is the new sealant paintable?
Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.
Is it worth trying it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
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.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few photos.
Do you seal inside as well as outside?
Yes, we do both. Inside, the joint between frame and plaster is sealed neatly, using a paintable sealant if you want to decorate.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
- Misting between the panes of a double-glazed unit (that needs a new unit)
If you are not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer.

Windows and doors in Lower Bush
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Starkey Castle (about 1.4 miles south-east) are a reminder that the area around Lower Bush 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 is traditional sand mastic.
Managing a site like Cuxton Community Infant School? Then the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Cuxton station? Then renewing tired window mastic between tenants heads off draught and damp complaints.
