Standard white frames in common sizes arrive in 2 to 3 weeks. Coloured, foiled or non-standard sizes stretch to 5 to 7 weeks. Ask the supplier to print the order confirmation with the dispatch date and the delivery date so you can book the fitter with a real window.
Width and height are taken brick to brick in 3 spots: top, middle, bottom. The smallest reading sets the frame size after a 10 mm fitting gap all around. Old houses may have out-of-square frames, so note the diagonal difference. Never trust a quote based on rough measurements taken by phone.
Newer windows must include trickle vents or a mechanical extractor to meet building rules. Removing them causes mould and stale air, even with double glazing. Keep trickle vents open in kitchens and bathrooms. The 2-position slider lets you regulate airflow without leaving the window cracked open.
Choose the frame style to match your wall opening. Casement frames swing open, tilt-and-turn frames tilt in, and fixed frames do not open. Check the reveal depth in millimetres so the frame sits flush with plaster. Ask the fitter to confirm the wall makeup before ordering a profile.
Glazing beads hold the glass inside the frame. External beads are safer against intruders, internal beads are easier to service. Ask which type you have and how to pop a bead out without breaking it. Keep a spare bead set aside in case one cracks during future reglazing.
Old glass and timber frames count as construction waste and should not go in a normal bin. Ask the fitter to break down the old units on site and take them away, leaving the driveway clean. Keep the waste transfer note with your invoice for proof of legal disposal.
Condensation inside the glass means the seal is gone. Drafts around the edges point to broken gaskets or warped timber. Soft black spots on sills show water has pooled for months. Stiff handles and cracked putty mean the unit is past repair and replacement is the safer choice now.
Foam filling the entire gap stops the frame from moving with temperature changes. Packers left behind under the sill create cold bridges. Silicone applied over dirty trim peels within months. Ask the fitter how they seal the perimeter and how they pack the frame before screwing it in.
Good windows depend on rubber gaskets that compress evenly around the sash. Ask to see the gasket profile and check that corners are mitred or vulcanised, not glued. After fitting, close the sash on a piece of paper; if you can pull it out without tearing, the compression is too loose.
If you face a road or railway, acoustic laminated glass cuts noise by 6 to 10 decibels over standard double glazing. The panes have a sticky interlayer that dampens vibration. Ask for the Rw rating in writing and compare it across quotes rather than trusting vague terms like soundproof.
