Window mastic for homes and businesses in Piddington
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. Typical jobs include gaps where the sill meets the wall and mastic that’s falling out in pieces, across timber windows & doors, composite doors and patio & French doors.
Homes in small places like Piddington often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A neat, narrow bead in a colour to match keeps the clean look.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Keep jet washers away from the mastic
- Don’t paint over the silicone
- Walk round the house once a year and look at the joints
- Use gentle cleaners on frames and sealant
Most silicone sealants won’t take paint, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Work for landlords, hotels and businesses
We also work for property managers and facilities teams in Piddington and across Oxfordshire. Several sites can be quoted together, and we’re fully insured for the work.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.
What we are called out for in Piddington
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
It’s worth asking for a quote if you see:
- Leaking joints at the ends of sills
- Damp patches on the reveal after heavy rain
- Gaps between the frame and the inside reveal
- Gaps left after new windows were fitted
For an older house near a landmark such as Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

- How hidden problems are handled

Leave it or put it right?
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Where a wall is exposed, as many are in small places like Piddington, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
What window mastic looks like in Piddington
With historic houses such as Boarstall Tower (about 2.1 miles south-west) nearby, there’s older building stock in the area around Piddington as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
