About our window mastic in Wherwell Wood
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on timber windows & doors, composite doors and patio & French doors, and common reasons people get in touch are draughts coming in around windows and doors and damp patches on the reveal after heavy rain.
In a village or hamlet like Wherwell Wood, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What window mastic looks like in Wherwell Wood
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Church of St Peter, the joint between an old wall and a newer frame is normally the first place rain gets in. Schools such as Wherwell Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Signs you need window mastic in Wherwell Wood
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Cold air getting in at the frame edge
- Hard, cracked sealant around windows
- Black, perished sealant on frames
- Damp patches on the reveal after heavy rain
For landlords with property near Andover station, renewing tired window mastic between tenants heads off draught and damp complaints.

Leave it or put it right?
Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. Problems with the glass or gaskets are for a window company, and we’ll say so. Where a wall is exposed, as many are in small places like Wherwell Wood, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before any work begins. The work generally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere like Wherwell Wood needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about access, such as stairs, a lift or high-level joints

Advice
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Aftercare tips
Once the sealant has cured, a few habits help it last:
- Paint up to the joint, not over it
- Avoid harsh chemicals near the mastic
- Wipe condensation off the frames
- Clean frames with a soft cloth and soapy water
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. Resealing closes it.
