Replacing windows: questions before the quotation
Prepare a window brief covering comfort, noise, shading, ventilation, installation details and the practical constraints of an apartment building.
A window is more than its frame material. Glass, seals, opening arrangement, shading and the connection to the wall all influence the result. If you are replacing windows in a Greek apartment, ask suppliers to respond to the same performance and installation brief.
Describe the problem clearly
Record whether your main concern is draughts, overheating, noise, water entry or difficult operation. Note orientation and how each room is used. A bedroom facing a busy street may have different priorities from a shaded kitchen. Ask a qualified adviser which measurements and specifications are relevant to your property.
Compare the whole window
Request performance information for the complete proposed product rather than a single component. Check glazing, frame, seals, hardware and opening method together. Ask how external shading and ventilation will be addressed. A tighter replacement should be considered alongside the room’s ventilation strategy, not in isolation.
Study the installation junction
Clarify removal, repair of surrounding surfaces, sealing, thresholds, drainage and making good. Ask how shutters, insect screens and existing finishes will be coordinated. In an apartment block, check facade and shared-building requirements with the appropriate professionals before ordering. A quotation should explain what happens around the window, not just what is delivered.
Think about everyday operation
Try handles and opening modes. Consider cleaning access, furniture positions, safety needs and replacement parts. Confirm warranty responsibilities for both product and installation. Keep the specification and care instructions. Do not select a product only because it uses a fashionable material or promises an unverified percentage saving.
Your practical checklist
- List the problem for each opening.
- Compare complete product specifications.
- Include surrounding repairs and installation details.
- Coordinate ventilation, shading and building requirements.
