We work on composite doors, aluminium frames and timber windows & doors, and people most often call us about mastic that has split away from the wall and gaps between the frame and the inside reveal.

What the job involves on each surface
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Stock homes and the weather
Historic houses like Ingatestone Hall (about 2.5 miles west) are a reminder that the area around Stock has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. If you let a flat or house near Billericay station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Signs you need window mastic in Stock
Older frames were often sealed with products that set hard. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
Look out for any of the following:
- Damp patches on the reveal after heavy rain
- Whistling draughts around closed windows
- Cracked or shrunken mastic around the frame
- Leaking joints at the ends of sills
Schools such as Stock Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Your questions about window mastic in Stock
Is Stock in your area for window mastic?
Yes, Stock is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing.
Will you come out to Stock?
Yes. Stock is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Do the sealants smell?
Sometimes, a little. Any smell clears as the sealant cures.
What should I tell you?
The location, the problem and the rough size of the job. If you can, email a few photos.
How long does it take to reseal the windows on a house?
The work takes anything from an hour or two to a full day, depending on how many frames there are. Access and how stubborn the old mastic is affect the time most.
How long should I leave it?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used.
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.
Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear any debris from frame drain holes
- Ventilate rooms so frames do not stay wet inside
- Keep jet washers away from the mastic
- Don’t paint over the silicone
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
Why it’s worth doing now in Stock
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Stock, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part, and we will explain the quote if you ask.

What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Stock needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- For indoor joints, keep the area dry beforehand if you can
