Window mastic for homes and businesses in Crockham Heath
Behind a thin line of old mastic there’s sometimes a deep void. Packing it solid with sealant gives a joint that can’t flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. We work on uPVC windows, aluminium frames and composite doors, and people most often call us about damp patches on the reveal after heavy rain and cracked sealant at the sill ends.
Outdoor sealant needs dry, clean surfaces, so work on frames around Crockham Heath is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How it works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for a few frames, or a day or more for a whole house and we leave things clean and tidy. For a village or hamlet like Crockham Heath, the journey is planned in advance: 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.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Signs you need window mastic in Crockham Heath
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
It’s worth asking for a quote if you see:
- Damp patches on the reveal after heavy rain
- Sealant in the wrong colour for the frame
- Untidy mastic left by window fitters
- Draughty joints inside around the window
If you let a flat or house near Newbury station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why it’s worth doing now in Crockham Heath
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. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Crockham Heath, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid harsh chemicals near the mastic
- Keep paint off silicone joints
- Look round the frames every year or so
- Keep jet washers away from the mastic
Try not to touch the new joint while it cures, following the cure time we give you. Do not point a pressure washer at the joints.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
Windows and doors in Crockham Heath
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Benham Park (about 1.8 miles north) are a reminder that the area around Crockham Heath 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.
If you live in an older home near Parish Church of St Michael, the joint between an old wall and a newer frame is generally the first place rain gets in. For site and facilities teams at buildings such as Enborne C.E. Primary School, the mastic around its windows and doors needs looking after like any other building’s.
