Window mastic in Oxnam
If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty and quietens the whistle on windy days. Where the air is getting in through the window itself, we’ll say so. If you are dealing with cracked sealant at the sill ends and mastic that’s falling out in pieces, we can put it right, on uPVC windows, timber windows & doors and composite doors alike.
Outdoor sealant needs a dry surface, so window work around Oxnam is planned around the weather. Tell us about access to all the windows and doors, upstairs included.
Every job is covered by our 12-month guarantee.

Windows and doors in Oxnam
Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.
In the older streets around Oxnam Parish Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. In and around Oxnam, as anywhere, good window mastic starts with a clean, dry, properly prepared joint.

Why deal with it now?
A quick bead over the top of old mastic looks like an easy fix, but it will not grip old, dirty sealant. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. In a place like Oxnam, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Aftercare tips
A little care helps the new joints last. We recommend:
- Keep solvents and bleach off the sealant
- Do not aim a pressure washer at the joints
- Keep timber frames painted
- Clean frames with a soft cloth and soapy water
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. Any of these is worth a call.
What the job involves on each surface
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We can talk through the options.
Landlord and commercial work in Oxnam
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Housing providers, facilities teams and property managers book us too in Oxnam and across the Scottish Borders. We can quote a run of properties together.
The process
Before we leave, we go over the finished joints with you and tell you how long to leave it. The work normally takes most of a day for a typical house, less for a few frames, depending on the amount of work. For a place like Oxnam, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any previous sealing or DIY attempts
- Clear items away from the joints we’re working on
