COMMON SASH WINDOW PROBLEMS
Does your window do any of these?
Many sash window problems can be rectified rather than replacing the window. These are the issues Matt fixes most often across Sydney.
01
Painted shut
Years of repainting seal the sashes to the frame. Matt cuts the paint line, frees each sash and services it to run smoothly.
02
Snapped sash cords
Worn cords fray and snap, so the sash drops or jams. Matt fits new cords to every sash and rebalances the weights.
03
Won't stay open
Loose weights or tired spiral balances let the sash slip. Matt reconnects the weights or replaces the balances so it holds.
04
Rotten timber
Moisture decays sills and bottom rails. Matt rebuilds the damaged timber with Evermend epoxy, so the window stays.
05
Rattling in the wind
Loose sashes and worn beads let windows rattle. New beading with high performance draught seals cushion the sashes and hold them firm and quiet.
06
Draughts and noise
Gaps and worn seals let in cold air, dust and noise. Draught proofing seals them, and acoustic glass can go further.

WHERE CRAFTSMANSHIP MEETS INNOVATION
Restore the window you have. Don't replace it.

WHAT YOU'LL NOTICE
Quieter rooms
Sealed gaps and acoustic glass take the edge off Sydney traffic and flight paths.
Warmer winters
Brush pile draught proofing stops the cold air and lost heat at the source.
Effortless operation
Rebalanced sashes glide open with one hand and stay exactly where you leave them.
Original character
Every upgrade is discreet, true to the original design and invisible from the street.

QUESTIONS & ANSWERS
Sash window repair Q&A
The questions Matt hears most. Anything else? Call 0409 448 107.
Are quotes really free?
Yes. Matt assesses your windows on site and gives you a clear, itemised quote, at no cost and with no obligation.
Who looks after the work?
Matt does. MST is owner operated, so the person who quotes your job oversees it from start to finish and signs off every window.
Will draught proofing change how my windows look?
No. The high performance seals sit discreetly within the frame, so your windows keep their original appearance.
Do you clean up after the job?
Always. Floors and furniture are protected while Matt works, and he removes every scrap and tests each window with you before he leaves.
Can old timber windows be as efficient as new ones?
Properly restored and upgraded with the right products (brush pile seals, acoustic or vacuum insulated glass), they can match or outperform modern windows.
Can you upgrade the glass without replacing the window?
Yes. Broken or old panes can be replaced with acoustic, privacy or slim vacuum insulated glazing that fits the original sashes.
Are you licensed and insured?
Matt is a fully qualified, licensed carpenter (Lic. 215324C) with more than 25 years at the trade, and every job is backed by a workmanship guarantee.
Which areas of Sydney do you cover?
All across Sydney, including North Sydney, the North Shore, the Northern Beaches and the Inner West. Unsure? Call 0409 448 107.
How much do sash window repairs cost in Sydney?
Every home is different, so Matt gives you a free, itemised quote on site. The price depends on the number, size and condition of your windows, and there are no hidden extras.
How long does the work take?
It depends on how many windows need work and their condition. Matt gives you a clear timeframe with your quote and keeps disruption to a minimum.
Is it better to repair or replace old sash windows?
Repair is often the better choice. Original timber is high quality, and restoring it keeps the character of your home. Matt will give you an honest view on site.
Do you work on heritage and modern homes?
Yes. Restoring the original windows is usually the preferred approach for heritage homes, and Matt is happy to work alongside your builder or architect. Modern timber windows get the same care.
Can you repair rotten window timber?
Yes. Matt cuts back the decayed timber and rebuilds it with Evermend epoxy timber repair, then sands and paints it to match. It saves the original window rather than replacing it.
Do you replace seized pulleys and missing weights?
Yes, definitely. Seized pulleys are freed or replaced, and missing or mismatched weights are replaced so every sash balances properly.
