Maintenance & Troubleshooting
My new windows are drafty. What should I do?
Contact us right away, since fresh installations shouldn’t draft. This usually points to an installation or sealant issue that our crew can diagnose and correct under your workmanship warranty.
My windows are letting in cold air, or even ants. Why?
This is almost always a sign of gaps around the frame from improper sealing or shimming. See our detailed case study on brand-new windows letting in cold air and ants for what to check.
My window has condensation between the panes. What does that mean?
Fogging trapped between glass layers means the sealed unit’s gas fill has escaped and the seal has failed, which is different from harmless surface condensation. This is covered under our lifetime glass warranty.
Do I need to top up the argon gas in my windows?
Argon slowly diffuses over many years even in an intact seal, gradually reducing insulation performance. Our guide on the cost to replace argon gas in windows explains when it’s worth doing.
My window won't open or close properly. What should I check?
Clean the tracks of dirt and debris, then apply a silicone-based lubricant to hinges and rollers, never oil or WD-40. If the problem persists, contact us for a warranty inspection.
How do I clean my vinyl windows?
Use mild soap and water with a soft cloth, avoiding abrasive pads, bleach, or high-pressure washers that can scratch or discolour the frame finish over time.
How often should windows be cleaned and inspected?
Clean glass at least twice a year and inspect weatherstripping and caulking annually, replacing either if cracked or compressed, since worn seals are the most common cause of drafts and leaks.
