When to call us in Loxhill
Sun, frost and rain wear sealant out. Sunlight dries the surface out, and over the years it loses its give, cracks and comes away.
Keep an eye out for any of the following:
- Old mastic that has gone black or come away
- White mastic on grey or black frames
- Untidy mastic left by window fitters
- Rain getting in at the frame or under the sill
If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

About our window mastic in Loxhill
There are two joints on most windows. Outside, the mastic keeps rain out; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. We work on window sills, patio & French doors and uPVC windows, and people most often call us about gaps left after new windows were fitted and a bead that doesn’t match the frame.
Outdoor sealant needs dry, clean surfaces, so work on frames around Loxhill is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee.

The process
When we get to you, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Loxhill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- Finally we tidy up and check each joint.
Preparing for the visit
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
Getting a quote

Different surfaces, different methods
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.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We will tell you which suits your home.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep solvents and bleach off the sealant
- Repaint timber before it’s bare
- Wash the frames with mild soapy water
- Paint up to the joint, not over it
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
Leave it or put it right?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic usually deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. In a small place like Loxhill, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
