About our window mastic in Aston Rowant
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. Typical jobs include hard, cracked sealant around windows and rushed sealant from a window installation, across window sills, aluminium frames and uPVC windows.
In a village or hamlet like Aston Rowant, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Your questions about window mastic in Aston Rowant
Is Aston Rowant in your area for window mastic?
Yes. Our work covers London and the South East, and Aston Rowant is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.
What guarantee comes with window mastic in Aston Rowant?
All our work, in Aston Rowant and everywhere else, comes with a 12-month guarantee. We are also fully insured and ARBOMaster approved.
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. You’ll know the timing when we quote.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area.
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 resealing stop a draught around my window?
In many cases. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.
Can you get sealant to suit coloured frames?
Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.
I rent my home. Can I book you?
Yes. Check with your landlord; we can send the quote to them too.

What happens on the day
On the day, we start by going over the job with you, so you know exactly what we are doing. We protect the surfaces around the joints before work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. In a small place like Aston Rowant, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Deep gaps are filled with backing rod to set the depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Preparing for the visit
- Let us know about earlier repairs to the joints
- Where the joints are inside, avoid wetting them before we arrive
- Let us know if you’ve seen damp or leaks

Frames and glazing around Aston Rowant
With historic houses such as Adwell House (about 2 miles west) nearby, there’s older building stock in the area around Aston Rowant 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’s traditional sand mastic. 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.
For site and facilities teams at buildings such as Aston Rowant Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Draughts through the window seals rather than the frame
- Faulty window hardware
- A failed sealed unit that has misted up
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
Joints and surfaces we work on
- Composite doors
- Window sills
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- uPVC windows
What the job involves on each surface
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.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We’ll tell you which suits your home.
Why deal with it now?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Aston Rowant, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.
Why Aston Rowant clients choose us
- We agree the colour with you first
- Sanitary silicone with an anti-fungal additive in wet areas
- Experience in homes, commercial sites and hotels
- White, clear, grey or another colour, product permitting
Common problems we fix in Aston Rowant
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
The most common problems we see are:
- Mastic that’s falling out in pieces
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
- Gaps left after new windows were fitted
If you live in an older home near Church of St Peter and St Paul, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
