Window Mastic in Earlston
We cover Earlston for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Rain getting in at the frame or under the sill
Common problems we fix in Earlston
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
The problems people generally mention when they call are:
- Old mastic that has gone black or come away
- Leaking joints at the ends of sills
- Gaps left after new windows were fitted
- A bead that doesn’t match the frame
If you live in an older home near Earlston Parish Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Window mastic in Earlston
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. If the draught is through the window seals instead, we will tell you. If you are dealing with cracked internal joints between frame and plaster and cracked or shrunken mastic around the frame, we can put it right, on window sills, composite doors and timber windows & doors alike.
In and around a place like Earlston, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain, so the mastic there works hard.
Whatever the size of the job, it’s backed by our 12-month guarantee in Earlston and across the Scottish Borders.

Your questions about window mastic in Earlston
Do you cover smaller places like Earlston?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Tweedbank station?
Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.
Can resealing stop a draught around my window?
In many cases. The gap between frame and wall is a common source of draughts, and sealing the inside and outside joints closes that path.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Where do you work from?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Can new sealant go over the old?
No. The old sealant always comes out first.
Can you reach windows above the ground floor?
Normally, yes. Access is planned before work begins.
What else we do in Earlston
How the visit works
The work is kept neat and contained to the area we are working on, so you can get on with your day. The job usually takes most of a day for a typical house, less for a few frames, and we explain the cure time before we leave. For a place like Earlston, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Preparing for the visit
- Keep children and pets away from the work area
- Let us know if you’ve seen damp or leaks
- Mention any sign-in or site rules at work premises

Advice
Landlords, agents and businesses in Earlston
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
For anyone letting property in or around Earlston, jobs at different addresses can be quoted together. Send us the addresses and the work at each.
Windows and doors in Earlston
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Sash and case windows are common in older Scottish homes, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
Managing a site like Earlston High School? Then its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Tweedbank station, renewing tired window mastic between tenants heads off draught and damp complaints.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Wash the frames with mild soapy water
- Do not use solvent cleaners on the joint
- Make sure the drainage slots are not blocked
- Paint up to the joint, not over it
Silicone can’t normally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
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 happens if it’s left?
Draughts and leaks don’t always mean new windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. Problems with the glass or gaskets are for a window company, and we will say so. Around Earlston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first.

Should I try it myself first?

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What the job involves on each surface
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
