The truth is, old sash windows aren’t built for 2025 without a bit of help. London’s damp winters and blustery storms take their toll, but that doesn’t mean you’re stuck with the problems—or that you need to rip them out.

Sticking Sashes: Why They Jam and How We Sort It
Ever tried opening a sash window only to feel like you’re fighting a losing battle? It’s a familiar struggle in London homes. The culprits are usually layers of old paint gumming up the works, timber swollen from relentless damp, or frames warped by decades of wear. You tug, you push, and still, it won’t budge. That’s not just frustrating—it’s a sign your windows are crying out for attention.
We’ve honed the art of freeing stuck sashes without sacrificing their character. Our approach is precise and practical, tailored to London’s unique climate. Here’s how we do it:
- Paint’s the problem? We strip it back with care, using carbide blades to clear the runners—years of buildup vanish in moments.
- Swollen timber from wet winters? We plane the edges down, ensuring a smooth fit without hacking away the original wood.
- Warped beyond a quick fix? We craft replacement sashes that mirror the Georgian or Victorian profiles you love, slotting in seamlessly.
Imagine the satisfaction of a window that slides open effortlessly, no more wrestling matches required. London’s weather might twist timber, but we’ve got the know-how to fight back—and win. Your home deserves that ease, and we’re the ones to deliver it.
Draughty Windows: Banishing the Chill for Good
There’s nothing worse than a cold draught sneaking through your sash windows on a bitter London evening. You feel it in the chill near the glass, hear it in the faint whistle of gaps, and see it in those climbing energy bills. Worn brush seals, cracked putty, or single panes struggling against the wind—these are the usual suspects. It’s not just discomfort; it’s heat slipping away, pound by pound.
We’ve got draughts in our sights, and we don’t mess about. Our fixes lock out the cold while keeping your windows’ charm intact. Here’s what we bring to the table:
- Gaps letting in air? We fit modern brush seals along the edges—simple, effective, and invisible.
- Glazing loose or cracked? We re-putty with a linseed oil mix, sealing every pane tight against the elements.
- Want lasting warmth? We retrofit slim double glazing—6mm gaps that boost insulation without breaking heritage rules.
One quick fix, and your home feels snug again—warmth stays where it belongs. With energy costs soaring, draught-proofing isn’t just comfort; it’s a smart move. We’ve helped countless Londoners reclaim their cosiness—your draughty days could be numbered too.
Broken Cords: Stopping the Slam
That heart-stopping thud of a sash window dropping shut is a sound every London homeowner knows too well. It’s the telltale sign of frayed cords or jammed weights—relics of Victorian engineering that weren’t meant to last forever. Maybe the sash won’t stay up, or it crashes down the moment you let go. Either way, it’s a problem that turns a simple airing-out into a risky chore.
We’ve mastered the fix for this classic London woe, and it’s simpler than you’d think. Our team gets those sashes working smoothly again with a process honed over decades:
- Access the weight pocket by easing off the stop bead—no fuss, no damage.
- Swap out old cotton for waxed nylon cord—it’s tough, reliable, and built for the long haul.
- Free up seized pulleys with a dash of WD-40, restoring that effortless lift.
Your windows should lift and hold, not fight you at every turn. We recalibrate weights in hours, turning a slamming nuisance into a thing of the past. It’s a fix every London home deserves—practical, lasting, and true to its roots.
Rotten Timber: Saving Your Frames from Ruin
Spotting soft, crumbly wood on your sash window frames is enough to make any homeowner wince. London’s relentless rain seeps into sills and rails, and if the paint’s been neglected, rot sets in fast. Black spots or spongy patches aren’t just ugly—they’re a warning your windows are on borrowed time. But here’s the good news: rot doesn’t have to mean the end.
We’ve turned countless rotting frames into sturdy showpieces, and we do it with care. Our approach keeps your windows standing strong:
- Early rot? We chisel out the damage, then treat it with wood hardener and two-part filler—solid as new.
- Too far gone? We replace sections with FSC-certified oak, matching the original curves and lines.
- Prevention’s key—we repaint with weatherproof coats to keep rot at bay for years.
From ruin to resilience, your frames can have a second life. Timber’s a survivor, and with our craft, it’ll stand up to London’s wettest seasons. Why let decay win when restoration’s this close?
Rattling Panes: Quieting the Noise
When the wind picks up, do your sash windows turn into an unwanted percussion section? That rattling hum isn’t just irritating—it’s a sign of loose panes, worn balances, or glass too thin for London’s gusts. It steals your peace, turning a quiet evening into a battle with the elements.
We’ve got the tools and the know-how to hush those noisy windows for good. Our fixes are straightforward but transformative:
- Loose panes clattering? We secure them with fresh glazing beads or putty—silence restored.
- Sashes wobbling? We fit spring balances to steady them, no more shakes.
- Noise a constant? We upgrade to 4mm acoustic glass, cutting the din without changing the look.
Peace isn’t a luxury—it’s what your home should offer. One tweak from us, and that rattle becomes a memory. What’s that noise stealing from your quiet? With our help, it’s nothing at all.
Why Old Sash Windows Are Worth Saving
Old sash windows aren’t just fixtures—they’re London’s heartbeat. The symmetry of a Georgian frame or the elegance of a Victorian sash tells a story of craftsmanship that mass-produced uPVC can’t touch. Sure, they creak and leak if ignored, but with a bit of love, they’re more than worth the effort. They tie your home to the city’s past while lifting its future.
The payoff’s real, and it goes beyond looks. Restore them right, and you’ll see:
- Lower bills—insulation upgrades like double glazing keep heat in, easing the strain on your wallet.
- Higher property value—London buyers covet heritage features done well.
- Pride in preservation—keeping these windows alive feels like honouring the city itself.
Here’s how they stack up:
| Feature | Old Sash | Upgraded Sash |
| Charm | High | High |
| Insulation | Poor | Excellent |
| Maintenance | Frequent | Reduced |
London’s past fuels its future, and your sash windows are proof. They’re not relics to replace—they’re treasures to revive. With the right care, they’ll shine for decades more.
