About our window mastic in Wildhern
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. We work on aluminium frames, window sills and timber windows & doors, and the jobs we see most are gaps left after new windows were fitted and mastic that’s falling out in pieces.
Mastic can only go onto a dry, clean joint, so window work in Wildhern is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Every job comes with our 12-month guarantee, wherever you are in Hampshire.

What window mastic looks like in Wildhern
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Hatherden Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Andover station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Christchurch, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Keeping the joints in good condition
So the new joints stay in good condition:
- Don’t aim a pressure washer at the joints
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. Somewhere like Wildhern needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- Next the failed sealant is cut away and the joint cleaned.
- 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.
- We clear up and check every joint is fully closed.
Preparing for the visit
- Keep children and pets away from the work area
- Clear items away from the joints we’re working on
- Tell us if parking is tricky

Advice
What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. The sealant must cope with it without cracking.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Why it’s worth doing now in Wildhern
Resealing frames is a short job: the visit takes most of a day for a typical house, less for a few frames. 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 Wildhern, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Work for landlords, hotels and businesses
For anyone letting property in or around Wildhern, jobs at different addresses can go on one quote. Just tell us the addresses and what each one needs.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
