Is Triple-Pane glass worth the cost in Colorado?

For many Denver homes, yes. Triple-Pane offers superior noise reduction and maximum insulation against sub-zero nights. Our factory-direct pricing makes this upgrade very affordable.

Do I need a permit or HOA approval for window replacement?

In most Denver municipalities, a permit is required. We handle all city permitting for you. For HOAs, we provide the necessary specs and brochures to help you get approval quickly.

Replacement Windows in Denver.
Built for Altitude.

Q: Can you really install windows during a Denver winter?

Absolutely. We replace windows year-round. In the colder months, our crews use a 'one-out, one-in' method, closing off the room being worked on to minimize heat loss.

Q: How long does it take to install new windows?

Most residential projects are completed in 1 to 2 days. An experienced crew can typically install 10-15 windows per day.

In Denver, your home endures some of the most drastic temperature fluctuations in the nation. From the scorching, high-altitude summer sun to sub-freezing winter nights, your windows, siding, and doors are the critical barrier standing between you and the elements. If you are battling cold drafts, UV-faded furniture, or skyrocketing utility bills, your home’s exterior envelope is likely failing to perform.

Denver weather can be unforgiving. When hail leaves dings, cracks, or hidden structural bruises on your exterior, replacement isn’t just about repairs—it is an opportunity to upgrade. We specialize in helping homeowners turn post-storm frustration into a complete exterior transformation.

We install advanced fiber cement and engineered wood siding designed to shrug off future storms. These materials provide the deep, authentic texture of wood that enhances your home’s character, combined with the armor-plated durability required to thrive in our hail alley.

Common Questions from Denver Homeowners

Renovating your home’s exterior in Colorado comes with unique challenges. Here are honest answers to the questions we hear most often.

Absolutely. We replace windows year-round. In the colder months, our crews use a “one-out, one-in” method, closing off the room being worked on to minimize heat loss. We don’t leave your home exposed. In fact, replacing drafty windows in winter provides immediate relief from heating bills.

It is not uncommon to find hidden water damage once old windows are removed. Our installation teams are equipped to handle minor framing repairs on the spot. If we discover significant rot, we stop, show you the issue immediately, and explain the necessary repairs to ensure your new windows have a solid, rot-free foundation. We never cover up a problem.

We treat your home with respect. Our crews use drop cloths to protect your floors and furniture, and we vacuum the work area thoroughly after each window is installed. We also haul away your old windows and all debris, leaving your home cleaner than we found it.

Most residential projects are completed in **1 to 2 days**. An experienced crew can typically install 10-15 windows per day. We will give you a specific timeline during your consultation so you can plan your schedule accordingly.

For many Denver homes, yes. While high-quality double-pane windows are a massive upgrade over builder-grade glass, Triple-Pane offers superior noise reduction (great for city living) and maximum insulation against sub-zero nights. Because we offer factory-direct pricing, you can often upgrade to Triple-Pane for the price competitors charge for Double-Pane.

In most Denver municipalities, a permit is required, especially if we are altering the size of the opening (e.g., meeting egress codes in basements). We handle all city permitting for you. Regarding your HOA: while we cannot sign for you, we provide all the specs and brochures you need to get fast architectural committee approval.

While traditional vinyl is cost-effective, it can crack during severe hail storms. We highly recommend Fiber Cement (James Hardie) or Engineered Wood (LP SmartSide) for Colorado homes. These materials are engineered to resist impact, protecting your home’s structure better than standard vinyl or aluminum.

Modern entry doors are miles ahead of older wood doors. Our Fiberglass and Steel options feature solid cores that resist kick-ins, reinforced strike plates, and multi-point locking systems. They provide the look of wood with the strength of a bank vault.
