Frequently asked questions about window replacement

Frequently asked questions about window replacement

Replacing windows is a significant upgrade for a home or apartment in Latvia. The right profile, insulating glass unit and professional installation improve energy efficiency, reduce noise and increase comfort. This article answers the most common questions, provides preparation checklists and contractor selection tips.

When is it really time to replace a window?

• Frames are deformed and sashes no longer close properly.
• Seals are damaged, causing drafts.
• Condensation between panes indicates a broken seal in the glass unit.
• High heating bills and cold window reveals.
• Excessive street noise.

If a window lets in cold and noise, replacing it usually pays off quickly through lower energy costs.

How to choose window type and glass unit?

• For Latvia’s climate, 2‑ or 3‑chamber insulated glass units with Low‑E coating and argon are recommended.
• PVC profiles with 5–7 chambers provide good thermal performance.
• Sound insulation depends on glass thickness and gap width; laminated glass is recommended for very noisy streets.

What affects the cost of window replacement?

• Size and complexity of the opening.
• Profile and insulating glass unit specifications.
• Additional work: removing old reveals, waste removal, leveling and finishing of reveals.
• Installation of sills, blinds, insect screens.

Do I need permits or notifications to replace windows?

• In most apartment cases in Latvia, replacing windows inside the apartment does not require a permit if the facade appearance is not changed.
• For multiapartment buildings and especially historic houses, check rules with the building manager (Īpašuma pārvaldnieks) or municipality.

How long does it take to replace one window?

• Standard removal and installation usually take 1–3 hours per window if the opening is prepared.
• Full work including new reveals and finishing can take 1–2 days per window depending on scope.

Preparation checklist for residents

• Clear the area around the window, remove curtains, blinds and plants from the sill.
• Remove fragile items and cover furniture.
• Ensure exterior access if installation requires facade work (balcony, scaffolding, lift).
• Agree on waste removal with the installation team.

What should I ask the contractor about warranties?

• Verify warranty terms for the profile, glass unit and installation (typically 3–10 years for products and 2–5 years for installation).
• Request a written contract listing the works and warranty responsibilities.
• Clarify responsibility for damage to reveals and finishes.

Can blinds and roller shades be installed with new windows?

Yes. Discuss mounting type (frame, reveal or opening) and compatibility with chosen profile depth. For integrated roller or Roman shades, ask about cassette or guide installation during window installation.

Window maintenance tips

• Wipe seals with a soft cloth and warm water.
• Avoid aggressive solvents on PVC and hardware.
• Lubricate hardware once a year and check sash adjustment.
