Secondary Glazing Maintenance & Care Questions

Question 1

How long does secondary glazing last?

Secondary Glazing Installers · Accepted Answer

Quality secondary glazing lasts 25-30+ years with minimal maintenance. Aluminium frames are corrosion-resistant and maintain their finish indefinitely. Glass is permanent unless damaged. Seals and hardware may need attention after 15-20 years. We have installations from the 1990s still performing perfectly. The key to longevity is quality materials and professional installation.

Question 2

How often should I clean secondary glazing?

Secondary Glazing Installers · Accepted Answer

We recommend: Glass cleaning: monthly or as needed (same as any window). Frame wipe-down: 2-4 times per year. Between-pane cleaning: 2-4 times per year (access by opening/removing panels). Track/seal inspection: annually. Deep clean: once per year. Regular light maintenance keeps your secondary glazing looking and performing its best.

Question 3

How do I clean between the two panes of glass?

Secondary Glazing Installers · Accepted Answer

All our secondary glazing panels are designed for easy access between panes. Depending on your panel type: Hinged panels - simply open like a door. Lift-out panels - lift and set aside. Sliding panels - slide to one side for partial access. Tilt-in panels - tilt inward for cleaning. Once open, clean both the inside of your original window and the secondary panel. No special tools required.

Question 4

What cleaning products should I use?

Secondary Glazing Installers · Accepted Answer

For glass: standard glass cleaner or warm water with a drop of washing-up liquid. Avoid abrasive cleaners. For frames: mild soap and water, avoid solvent-based cleaners on painted surfaces. For seals: wipe with damp cloth only - avoid chemicals that could degrade rubber. For tracks: vacuum loose debris, wipe with damp cloth. Simple household products work best.

Question 5

What does the warranty cover?

Secondary Glazing Installers · Accepted Answer

Our comprehensive 10-year warranty covers: Frames - against warping, discolouration, or structural failure. Glass - against delamination (laminated glass) or seal failure. Hardware - hinges, handles, locks, and sliding mechanisms. Seals - against degradation affecting performance. Installation - any issues arising from fitting. Normal wear and tear excluded, but we're always happy to help with maintenance queries.

Question 6

Can seals be replaced if they wear out?

Secondary Glazing Installers · Accepted Answer

Yes, seals are replaceable and this is normal maintenance after 10-15 years. Signs seals need attention: visible gaps or compression loss, increased noise or draughts, difficulty closing panels. Seal replacement is straightforward and costs £15-30 per panel. We offer a seal replacement service, or DIY-confident homeowners can purchase replacement seals from us.

Question 7

What if my sliding panels become stiff?

Secondary Glazing Installers · Accepted Answer

Stiff sliding is usually caused by debris in tracks or minor misalignment. Solutions: 1) Vacuum tracks and wipe clean, 2) Apply silicone spray (not WD-40) to tracks, 3) Check for visible obstructions, 4) Ensure panels are seated correctly. If problems persist after cleaning, contact us - adjustment is usually quick and may be covered under warranty.

Question 8

How do I maintain sliding tracks?

Secondary Glazing Installers · Accepted Answer

Track maintenance is simple: Monthly - quick vacuum to remove dust and debris. Quarterly - wipe with damp cloth, dry thoroughly. Annually - apply silicone-based lubricant (avoid oil-based products that attract dust). Never force stiff panels - always identify and resolve the cause. Well-maintained tracks ensure smooth operation for decades.

Question 9

How do I care for aluminium frames?

Secondary Glazing Installers · Accepted Answer

Aluminium frames are virtually maintenance-free. Routine care: wipe with damp cloth and mild soap 2-4 times yearly. Avoid: abrasive cleaners, scouring pads, solvent-based products. For powder-coated colours: same gentle cleaning applies. Aluminium doesn't rust, warp, or rot - it's why we specify it for longevity. Any stubborn marks usually come off with a non-abrasive cream cleaner.
