Window mastic for homes and businesses in Glympton
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before we start. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. If you have a bead that doesn’t match the frame and rain getting in at the frame or under the sill, we can help, whatever the surface.
Somewhere as small as Glympton, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

Looking after it afterwards
To keep the joints looking good and working properly:
- Make sure the drainage slots aren’t blocked
- Use gentle cleaners on frames and sealant
- Walk round the house once a year and look at the joints
- Wipe condensation off the frames
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.
What we’re called out for in Glympton
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Most people get in touch after spotting one of these:
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
- Draughty joints inside around the window
For landlords with property near Tackley station, renewing tired window mastic between tenants heads off draught and damp complaints.
What your quote should include
- Who turns up on the day
- Whether they’re fully insured
- What guarantee comes with the work
- Whether all the old sealant comes out first
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. In a small place like Glympton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Keep pets and children clear of the area while we work
- Tell us if parking is tricky

What sealant work can’t fix
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Soft or decayed wood in the frame
- A sash or casement that will not close properly
- Damp coming through the wall itself rather than the frame joint
If in doubt, call 0345 464 0079 or email us and we will say what we think.

What window mastic looks like in Glympton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Blenheim Palace (about 3.5 miles south) are a reminder that the area around Glympton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How the job changes by surface
Patio & French doors
Not every patio door leak is a mastic problem: worn seals, blocked drainage slots or a poor threshold detail can be the cause. We check before we reseal.
uPVC windows
We clean the frame edge carefully so the plastic is not marked, then the new bead is laid against the frame and the wall.
