About our window mastic in Highbridge
A cold draught around a closed window often comes from the frame edge. A new joint stops the air getting through. Where the air is getting in through the window itself, we’ll say so. We’re often asked to deal with black, perished sealant on frames and mastic that has split away from the wall, on uPVC windows, composite doors and timber windows & doors.
In a village or hamlet like Highbridge, 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 guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Surface by surface
Timber windows & doors
Timber moves with moisture as well as heat, so the joint must stay flexible. We seal onto sound, dry paintwork or timber.
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.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- The product the joint needs
- The old material and how stubborn it is
- Whether there’s mould to deal with
- Working hours on commercial sites
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first.
Helping us quote
Before you ask for a quote, have a think about:
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- Any access issues, like height or stairs
- What’s wrong with the joints now

Windows and doors in Highbridge
With historic houses such as South Stoneham House (about 4.2 miles south-west) nearby, there’s older building stock in the area around Highbridge as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Schools such as Colden Common Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Eastleigh station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. Homes close to St Mary's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

The process
We bring everything the job needs with us, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take a few hours for a few frames, or a day or more for a whole house. Somewhere as small as Highbridge, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- 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.
How to prepare
- Move anything stored near the joints
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks

Why act early in Highbridge
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Highbridge, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or drop us an email for an honest opinion and a quote.

Should I try it myself first?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
