Common Questions from Our Clients

Frequently Asked Questions

How long does a typical door installation take in Markham?

Most standard door installations are completed within half a day. However, custom doors or projects requiring frame modifications may take a full day. Our technicians arrive with all necessary tools and materials to minimize disruption. We always provide a time estimate during your initial consultation so you can plan accordingly.

What types of exterior doors do you install?

We install steel, fiberglass, and solid wood exterior doors from top manufacturers. Each material offers distinct advantages in terms of durability, insulation, and aesthetics. Our team helps you choose the best option based on your home's architecture and your budget. Additionally, we can install sidelights and transoms to complement your new entry door.

Do you offer energy-efficient door options?

Absolutely. We carry doors with high R-value insulation cores and weathertight seals. Energy-efficient doors significantly reduce heat loss during Markham's cold winters. Furthermore, they help lower your monthly heating and cooling costs. Our team can recommend ENERGY STAR-rated options that qualify for rebate programs.

Can you replace a door without changing the frame?

In many cases, yes. If the existing frame is structurally sound and properly aligned, we can install a new slab door. However, if the frame is warped, rotted, or damaged, replacement is recommended. Our technicians inspect the frame during the assessment and advise you on the best approach for lasting results.

Do you install garage doors with smart openers?

Yes, we install garage doors paired with Wi-Fi-enabled smart openers. These systems allow you to monitor and control your garage door from your smartphone. They also include safety features like auto-reverse sensors and battery backup. Our team ensures full integration and walks you through the app setup before we leave.

What warranty do you provide on door installations?

Fix One provides a comprehensive warranty on both labour and materials. The specific warranty duration depends on the door manufacturer and product selected. Typically, our labour warranty covers the installation for a minimum of one year. We also honour all manufacturer warranties and assist with any claims if issues arise.

How much does door installation cost in Markham?

The cost varies based on door type, material, and complexity of the installation. Entry doors generally range differently than interior or garage doors. We provide free, no-obligation estimates after an on-site assessment. Our pricing is transparent with no hidden fees, so you know exactly what to expect before work begins.
