Window mastic for homes and businesses in Froyle
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have cracked sealant at the sill ends and rain getting in at the frame or under the sill, we can help, whatever the surface.
Around Froyle, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Big or small, you get the same 12-month guarantee.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Do not paint over the silicone
- Check the mastic once a year
- Wipe condensation off the frames
- Keep timber frames painted
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
How we quote for window mastic
Call for a quick quote. What matters most is:
- The number and length of the joints
- Any working-time requirements on site
- The product the joint needs
- How many areas need sealing
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You will know the price before we begin.
What to tell us for a quote
What to tell us when you ask for a quote:
- Where the job is, and your postcode
- Roughly how big the job is
- A few pictures by email, if you can
- Whether it has been sealed before
Quotes start with a quick conversation. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, phone 0345 464 0079 or send us an email.
Why it’s worth doing now in Froyle
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Froyle can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
What it costs depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before any work starts.

What we are called out for in Froyle
Water runs down the glass onto the sill, and the ends of the sill, where it meets the wall, are where it gets in. When that sealant fails, water gets into the wall or under the frame.
Keep an eye out for any of the following:
- Cracked sealant at the sill ends
- Cold air getting in at the frame edge
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
Rented homes near Bentley (Hampshire) station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames for a typical job. For a village or hamlet like Froyle, 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.
- We start by checking each window and door with you.
- The old mastic is cut out and the surfaces cleaned back.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- We clear up and check every joint is fully closed.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises
- Tell us about any water getting in

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near Church of St Mary of the Assumption, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
