Customer Reviews

ELIJAH

We chose to replace both windows and doors to improve energy efficiency throughout the house. Before, the home struggled to stay warm in winter and cool in summer. Temperature fluctuations were common and uncomfortable. After installation, indoor temperatures are far more consistent.

Robert Rodriguez

We upgraded several windows and replaced the entry door at the same time. The old units affected both comfort and appearance. Daily use had become inconvenient. After installation, the house looks cleaner and feels quieter. Comfort improved noticeably.

Dennis Sanchez

Our windows and doors were outdated and didn’t match the rest of the home. Insulation issues became more obvious each season. Heating and cooling felt uneven. We decided it was time to replace them, and we did. The home now feels more comfortable and modern. The upgrade improved both performance and appearance

Frequently Asked Questions

How long does a Markham Windows & Doors project take?

Custom-ordered windows and doors typically have a three-to-four-week lead time; most residential installations are completed in one to two days.

What happens during a Markham Windows & Doors estimate visit?

The estimate is free. An installer measures the openings, assesses the existing units and reviews options before providing a fixed quote.

When does Markham Windows & Doors recommend replacing rather than repairing a window?

It says broken hardware, a stiff handle or a minor draft can usually be repaired. Moisture between panes, significant cold air around the frame, visible rot or warping may point to replacement.

What does the Markham Windows & Doors crew do during installation?

The crew protects floors and cleans up before leaving. It also walks through each unit to check that it opens, closes and seals properly.

Could a Markham Windows & Doors upgrade qualify for rebates?

The company says qualifying upgrades using its Energy Star-certified products may be eligible for federal and provincial rebates.
