Everyday New Window Installation Problems We Take Care Of

We've seen every issue a window installation project can run into. Here are the problems our clients call us about most often.

🌫️

Fog or Condensation Between the Glass Panes

This happens when the seal between double or triple-pane glass has failed, letting moisture get trapped between the layers. It cannot be cleaned since the moisture is sealed inside the unit itself. We replace the affected glass unit or the full window depending on the frame's condition.

🖼️

Window Won't Open or Close Smoothly

A sticking sash usually means the frame has warped or the hardware has worn down over years of use. Forcing it can damage the track or the sash itself. We assess whether hardware replacement or a full window swap is the right fix.

💨

Draft Felt Near the Window Even When Closed

Drafts usually point to failed weatherstripping or a frame that no longer seals evenly against the sash. Left alone, this steadily raises heating and cooling costs. We install new weatherstripping and correct any frame issues underneath.

📐

New Windows Don't Fit the Existing Opening

This is common in older homes with non-standard rough openings that don't match modern standard sizes. A poor fit creates gaps that undermine insulation and appearance. We measure precisely and order custom sizing when a standard unit will not work.

🌳

Old Wood Frame Has Rot or Soft Spots

Moisture exposure over years slowly breaks down wood framing, especially at the sill where water collects. Ignoring it can spread damage into the surrounding wall structure. We rebuild any compromised framing before the new window goes in.

💰

Heating Bills Rising With No Clear Cause

Aging windows with failed seals or thin frames often account for a meaningful share of unexplained energy loss. The effect builds gradually, making it easy to miss until the bill becomes noticeable. We assess whether replacement windows would meaningfully reduce that loss.

❄️

Single-Pane Windows Feel Cold to the Touch

Single-pane glass offers minimal insulation, letting cold radiate through the glass into the room. This creates uncomfortable cold spots near the window even with the heat running. We replace single-pane units with insulated double or triple-pane glass.

🔲

Screen Sags or Blocks the View When Not Needed

Fixed screens that stay in place year-round eventually sag and collect grime, and they slightly reduce airflow and visibility even when closed. We install retractable screens that tuck away into a housing until airflow is actually wanted.

🌧️

Water Leaking Around the Window During Heavy Rain

This usually points to improper flashing or caulking above the window that has failed or was never installed correctly. Left unresolved, water intrusion can damage interior walls and framing over time. We correct flashing and reseal the frame to stop water from getting in.

What Our Customers Say

Helena W.

Finally no more fogging between the panes

Our old windows had fogged up between the glass for years and I thought that was just how they were. Ontario Door & Window Pros explained it meant the seal had failed and replaced all six windows in one day. Completely clear glass now.

Raj P.

Triple pane made a real difference

We upgraded to triple-pane during a full-frame replacement and the bedroom that used to be freezing in winter is finally comfortable. The crew was efficient and cleaned up thoroughly after each window.

Denise C.

Good work, custom windows took a couple weeks

Our house has older bay windows so we needed a custom order, which added about two weeks to the timeline. Ontario Door & Window Pros was upfront about that from the start and the final install looked great.

Anthony M.

Retractable screens were the right call

We added retractable screens to the windows facing our patio and I love that they disappear when not in use. Installed at the same time as the new windows so everything looks seamless.

Ingrid S.

Explained exactly what was driving the price

The quote broke down frame condition, glass upgrade, and labor separately so I understood exactly what I was paying for. No pressure to upsell, just honest recommendations from the technician.

Colin B.

Whole house done in one visit, no issues since

Twelve windows replaced in a single day and every one operates smoothly six months later. The team from Ontario Door & Window Pros was professional from the first measurement visit through final walkthrough.
