Old windows are removed and the rough opening is inspected for rot, moisture damage, and proper flashing before the new unit goes in.

### Install and flash

New windows are set, shimmed plumb and level, and flashed properly at the head and sills to prevent any future water intrusion.

## Window Installation in Oshawa: questions answered.

### How much does window installation cost in Oshawa?

In Oshawa, window installation typically runs based on scope and materials. Pro House Maintenance gives every Oshawa homeowner a free, fixed-price written quote before any work begins, so there are no surprises.

### How much can new windows actually save on energy bills?

Double-pane low-e windows typically reduce heating and cooling costs by 15 to 25 percent compared to single-pane originals. Actual savings depend on your climate, existing insulation levels, and HVAC efficiency. Colder climates see proportionally greater benefit. Most homeowners recoup the installation investment within seven to ten years through energy savings alone, not counting comfort improvements and noise reduction.

### What is an insert replacement versus a full-frame replacement?

Insert replacements fit a new window unit into the existing frame: less invasive, faster, and lower cost, but the finished opening is slightly smaller than the original. Full-frame replacements remove everything including the frame, jamb, and trim, which is necessary when there is rot, moisture damage, or when you want to change the window size, shape, or style entirely. We assess frame condition during the free measure and recommend the right approach.
