Window mastic in Witley
A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for whistling draughts around closed windows and gaps where the sill meets the wall, on uPVC windows, window sills and composite doors.
Somewhere as small as Witley, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work comes with our one-year guarantee, wherever you are in Surrey.

What we can’t put right
Sealant is not the answer to every problem, and we will tell you before we start. Sealant won’t put right:
- Soft or decayed wood in the frame
- Broken hinges, locks or handles
- Condensation trapped between the panes
If you’re not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.

What we’re called out for in Witley
Mastic ages in the weather. UV light hardens the outside of the bead, until it loses its stretch and starts to crack.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Damp patches on the reveal after heavy rain
- Gaps left after new windows were fitted
- Gaps where the sill meets the wall
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.

What affects the cost of window mastic
For a quick quote, just ask. The main things that affect it are:
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- The size of the job
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.
What to tell us for a quote
To make quoting easier, let us know:
- Roughly how big the job is
- A few pictures by email, if you can
- The problem you’ve noticed
- Access, such as stairs, a lift or height

Your questions about window mastic in Witley
Can you do window mastic in Witley?
Yes. We work across London and the South East, and Witley is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Do you cover smaller places like Witley?

Is the new sealant paintable?
Most silicone cannot be painted. Let us know beforehand, and we will use a paintable product where it suits.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and we will quote it together.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do. Working times can be discussed when we quote.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
I’m a tenant. Can you help?
Yes. Check with your landlord; we can send the quote to them too.
Can I do 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.
Different surfaces, different methods
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that without cracking.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Witley homes and the weather
Historic houses like Loseley Park (about 4.6 miles north-east) are a reminder that the area around Witley 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. 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 landlords with property near Milford (Surrey) station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as The Chandler CofE Aided Junior School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Everything for the job comes with us, so a second trip is avoided where possible.

- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
