Regular Wood Window Installation Faults We Repair

We've seen every mistake a rushed installation can cause. Here are the problems our clients call us about most often.

💧

Window Leaking After a New Installation

Water intrusion after installation almost always traces back to improper or missing flashing rather than a defect in the window itself. Left unaddressed, hidden water damage can rot a frame from the inside within a few years. We install proper sill pans and head flashing on every job.

📏

New Window Doesn't Fit the Opening

A rough opening measured incorrectly leads to a window that either doesn't fit or requires expensive on-site modification. This mistake causes the most common project delays and cost overruns. We measure every opening at multiple points before ordering.

🌬️

Drafts Around a Recently Installed Window

Gaps between the frame and rough opening that aren't properly insulated let in drafts and undermine energy efficiency. Standard caulk alone rarely solves this. We use low-expansion spray foam sized correctly for the gap.

🌳

Wood Species Doesn't Match Existing Windows

Choosing the wrong species for a new installation can leave a visible mismatch with existing trim or windows elsewhere in the home. This mismatch is difficult to correct after installation. We help select species based on existing wood throughout the property.

🖼️

Operable Window Sticks or Binds

A slightly misaligned sash balance or hinge can make a window difficult to operate even when the installation looks correct. This issue often isn't obvious until months of use reveal it. We test every operable component multiple times during installation.

📋

Unsure if a Permit Is Required

Changing an opening's size or adding a new opening typically requires a municipal permit, and skipping this step risks a failed inspection later. Homeowners are often unaware of egress requirements for bedroom windows. We confirm code compliance before ordering materials.

🏗️

New Construction Timing Conflicts With Other Trades

Window installation needs to happen at a specific point in a new construction timeline, before siding but after framing is complete. Poor coordination with other trades can delay an entire project. We schedule installation to align with the broader construction timeline.

❄️

Old Single-Pane Windows Driving Up Energy Bills

Older wood windows with single-pane glass lose significant heat compared to modern double or triple-pane options. Continuing to use them keeps energy costs unnecessarily high. We install modern low-E glass suited to the home's climate exposure.

❓

Uncertain Whether to Match an Existing Window Style

Homeowners adding or replacing a single window often aren't sure whether matching existing styles exactly is necessary or worth the added cost. The right answer depends on the home's overall design and resale considerations. We walk through style options honestly based on the whole property.

Reviews

Straight From the People We Served

Grant P.

Flashing details were explained clearly

I had a bad experience years ago with a window that leaked because of lazy flashing work. Prime Windows Toronto walked me through exactly how they were sealing the new openings before starting. No issues at all through a rough winter.

Louise T.

New construction project went smoothly

We were building an addition and needed six new wood windows installed before the siding went on. The crew coordinated timing with our other trades well and every window fit perfectly on the first try.

Marvin K.

Great work, one window needed a custom order

Five of our six windows installed without a hitch but one opening turned out to be slightly out of square, which meant ordering a custom unit. Added about a week to the timeline but the crew explained why upfront.

Diane R.

Matched our existing oak trim perfectly

We wanted the new window to match our original oak windows elsewhere in the house. Prime Windows Toronto sourced the right species and the color match is honestly better than I expected.

Curtis B.

Handled the permit process without any hassle

We needed to change the size of an opening and I was dreading dealing with the city. The technician took care of the whole permit process and everything passed inspection on the first try.

Hazel W.

No drafts even in the coldest months

Our old windows let in noticeable cold air every winter. The new installation with proper insulation and sealing made an immediate difference. Prime Windows Toronto clearly knew what they were doing with the air sealing details.
