Most Door Warranties Leave You Exposed
Our Door Warranty Is Different
Most door companies offer warranties that sound impressive but fall apart when you read the details. Prorated coverage means your protection shrinks every year. “Limited” warranties exclude labor, installation issues, and even normal wear on hardware and seals.
At Ameritech, our door warranty works the same way as our window warranty: 40 years of straightforward, non-prorated protection on both materials and labor. That covers entry doors, patio doors, storm doors, and every component including frames, glass, hardware, weatherstripping, and finish.
If something fails within the warranty period, we fix or replace it. No depreciation schedules. No arguments about what’s covered. The same door installation team that put it in will be the ones who stand behind it.
What Our Door Warranty Covers
How Can We Offer This Kind of Warranty?
Our doors and installation are built to the same standard as our windows. We use reinforced frames, insulated cores, commercial-grade hardware, and precision installation techniques that eliminate the common failure points other companies deal with. Because our doors are installed right the first time, our warranty claims are exceptionally low.
We’ve been installing doors across the Colorado Front Range since 1994. That track record gives us the confidence to back every entry door, patio door, and storm door with the same industry-leading warranty we offer on our windows.
Learn More About The Climate in Colorado
- Winter (December to February): Colorado winters are cold, with temperatures ranging from 25°F to 50°F depending on the region. Some areas, especially in the mountains, experience heavy snowfall, while lower elevations like the Front Range can still see several inches of snow. Triple pane windows are ideal for reducing heat loss during these frigid months, keeping homes warmer and energy bills lower.
- Spring (March to May): Spring in Colorado is mild but erratic, with temperatures fluctuating between 40°F and 70°F. Sudden snowstorms can occur well into April, especially in higher elevations. Triple pane windows provide excellent insulation against these cold spells and help block out the high winds that are common during this season.
- Summer (June to August): Summers in Colorado are generally warm, with temperatures ranging from 70°F to 90°F in most areas, and the sun’s intensity is much stronger due to the higher elevation. This makes UV protection crucial. Triple pane windows with Low-E coatings help block harmful UV rays and reduce cooling costs by preventing excess heat from entering your home.
- Fall (September to November): Fall brings cooler temperatures, ranging from 45°F to 75°F, but early snowstorms and cold fronts can occur as early as October. Triple pane windows provide consistent insulation, keeping your home comfortable during these unpredictable transitions.
Across all seasons, triple pane windows are the best option for Colorado homeowners because they offer superior energy efficiency, excellent UV protection, and help maintain a stable indoor temperature, regardless of the state’s weather fluctuations.
