About our window mastic in Weyhill
Whether it’s one leaking patio door or every frame on the house, you’ll get a clear quote before any work starts. To get one, phone 0345 464 0079 or send us an email with the number of frames and any access details. If you have cold air getting in at the frame edge and rushed sealant from a window installation, we can put it right.
Homes in small places like Weyhill often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee, whatever its size.

Why act early in Weyhill
If you are painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished. Around Weyhill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Keep drainage slots and sill grooves clear
- Air rooms to keep condensation down around windows
- Repaint timber before it’s bare
- Do not aim a pressure washer at the joints
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
A small gap around a frame only grows. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
Weyhill homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

Do you need window mastic in Weyhill?
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces didn’t grip properly, and it lets go sooner than it should.
The problems people usually mention when they call include:
- Hard, cracked sealant around windows
- Gaps where the sill meets the wall
- Sealant in the wrong colour for the frame
- Whistling draughts around closed windows
If you live in an older home near Church of St Michael and All Angels, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

How the job changes by surface
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
The process
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like Weyhill, the journey is planned in advance: 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.
- First, we confirm safe access to each frame.
- 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.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Clear items away from the joints we’re working on
- Tell us about access, such as stairs, a lift or high-level joints
