🧼 Care & Maintenance

How do I clean and maintain PVC windows and doors?

Keeping your windows and doors in top condition is simple and helps extend their lifespan.

Routine Cleaning:

• Use a soft cloth or sponge with mild soapy water to clean the uPVC frames and glass.
• Avoid abrasive cleaners, scouring pads, or solvent-based products, as these can damage the surface.
• For stubborn marks, a non-abrasive cream cleaner designed for uPVC may be used sparingly.

Hardware Maintenance:

• Lubricate hinges, locks, and handles once a year using a light machine oil or silicone spray.
• Check for any loose screws or fittings and tighten them as needed.

Drainage Channels:

• Ensure that drainage holes at the bottom of the window frames are clear of debris to prevent water build-up.

What should I do if a window or door becomes stiff or misaligned?

Stiffness or misalignment can occur due to seasonal changes, wear, or debris buildup.

Troubleshooting Steps:

1. Inspect the hinges and tracks for dirt, grit, or obstructions.
2. Clean and lubricate moving parts with a silicone spray.
3. Check alignment by gently opening and closing the window or door. If it catches or doesn’t seal properly, it may need adjustment.
4. Adjust hinges or locking points if necessary—many modern uPVC units allow for minor adjustments using a screwdriver.

📏 Measuring Your Windows and Doors

How do I measure my windows and doors correctly?
Getting accurate measurements is essential to ensure your new windows and doors fit perfectly. Here’s a quick guide to help:

• Always use millimetres (mm) – Metric measurements are more precise and avoid conversion errors.
• Measure from the outside – Take measurements of the brickwork opening, not the old frame.
  • Height: From the bottom of the opening (under any removable cill) to the top.
  • Width: Brick to brick across the opening.
• Measure in three places – Openings may not be square. Measure top, middle, and bottom for height; left, centre, and right for width. Use the smallest measurement.
• Deduct 10mm – Subtract 10mm from both height and width to allow for fitting tolerance. This helps the installer position the frame correctly.
• Don’t measure the old frame – It may be warped or incorrect. Always measure the brickwork opening.
• Double-check your measurements – We can’t accept responsibility for incorrect sizes, and custom-made products are non-refundable.
• Cill included – If you require a cill, it’s included in the overall height you enter.
• Transoms – Transom Drops are measured from the top of the frame to the centre of the horizontal transom
• Mullions – Mullion dimensions are measured from the edge of the frame to the centre of the vertical mullion
• Midrails – Midrails are measured from the bottom of the frame to the centre of the Horizontal Midrail
