Cleaning and maintaining a residential window

Maintenance Guide

Keep Your Windows Performing Like New

Our European windows and doors are designed for minimal maintenance, but a little regular care goes a long way to protecting your investment.

Cleaning: Every 3 to 6 Months

Frames (uPVC & Aluminium)

Wipe down with a mild soap solution and a soft cloth or sponge. Rinse thoroughly. Avoid abrasive cleaners, solvents or bleach, these can damage the surface finish. A soft brush helps clean drainage channels and gasket grooves.

Glass

Use a standard glass cleaner or diluted white vinegar on a lint-free cloth. Clean in the shade to prevent streaking. Never use steel wool or abrasive pads on Low-E coated glass, you'll scratch the coating permanently.

Avoid: Acetone, white spirit, WD-40 on frames, pressure washers directed at seals, abrasive scourers.

Hardware: Lubricate Annually

A light application of a PTFE-based or silicone lubricant (not WD-40) on all moving hardware keeps handles, espagnolette rods, hinges and locking bolts operating smoothly for years. Apply with a thin nozzle to reach roller guides and pivot points.

Hinges

Apply a tiny drop of silicone oil to each hinge pin. Open and close several times to work it in.

Locking bolts

Apply PTFE spray to the locking rods and bolts. Test the handle mechanism to distribute evenly.

Seals (gaskets)

Wipe with a damp cloth and apply a light coat of silicone grease, prevents hardening and cracking in UV.

Annual Inspection Checklist

  • Check drainage slots at the base of frames are clear of debris, blocked drains can cause water ingress.
  • Inspect all rubber gaskets around the glass and frame perimeter, look for cracks, hardening or gaps.
  • Check any external silicone sealant around the frame-to-wall joint, reseal if cracked or separated.
  • Test all handles, locks and tilt mechanisms, they should operate without excessive force.
  • Look for any fogging or moisture between the glass panes, this indicates a failed sealed unit that needs replacement.
