Trusted by Loveland, Backed by Results

“Custom Exteriors did an outstanding job replacing the 6 windows in the sunporch room in our home. The old windows were drafty and hard to open. The new windows are easy to open, lock automatically when closed, and are air tight! Rick pays attention to detail, does quality work, and cleans the job site thoroughly before leaving. Upon completion of the install, Rick went over the operation of the windows and answered any questioned we had. I highly recommend Custom Exteriors.

Signs you should replace your windows or doors

Visible Signs of Damage:

If your windows or doors are drafty, allowing light through when shut, or becoming difficult to open, close, lock, or unlock, this could be a sign of warping, cracks, or broken seals. Windows and doors that have been painted or nailed shut compromise function and pose a serious safety risk during emergencies. Replacing damaged windows and doors with energy-efficient replacement windows ensures better safety, prevents further damage, and helps maintain the integrity of your home.

Rising Energy Costs:

Drafty or poorly installed windows and doors can lead to increasing energy bills. When energy is lost through inefficient windows or doors, it puts a strain on your heating and cooling systems. At Custom Exteriors, we offer energy-efficient windows and doors from high-quality manufacturers, helping you save on energy costs while improving your home’s overall comfort.

After Severe Weather or Storm Damage:

It’s essential to inspect your windows and doors after severe weather, especially in areas prone to extreme conditions. Homes exposed to high winds, heavy rain, or temperature swings should be checked regularly for damage. Upgrading to durable, energy-efficient windows and doors before further damage occurs can protect your home and save on long-term repair costs.

To Improve Curb appeal:

Whether you’re preparing to sell your home or simply want to improve its appearance, replacing old windows and doors is an easy way to boost curb appeal. High-quality, energy-efficient upgrades not only enhance the look of your home but also increase its value and attractiveness to potential buyers. Replacing old, drafty windows is a project known for its excellent ROI. At Custom Exteriors, we offer premium products that improve both the appearance and performance of your home.

If the windows in your Loveland home or business show any of these signs, contact one of our window consultants for a no-cost inspection.

Frequently Asked Questions About Replacing Your Windows In Loveland

Are energy-efficient replacement windows worth the investment in Colorado?

Yes. Colorado experiences extreme temperature swings, intense high-altitude UV rays, and freezing winters. High-performance windows featuring Low-E glass coatings and argon gas fills insulate your living spaces effectively, keeping your home comfortable year-round while significantly lowering your heating and cooling costs.

How long does a typical window replacement project take?

Most residential window replacements are completed in just one to two days. The exact duration depends on the total number of windows, whether you are replacing standard inserts or full-frame structures, and any surrounding trim repairs needed. Our crew works efficiently while maintaining meticulous attention to detail.

What is the difference between pocket installation and full-frame replacement?

A pocket installation places a new window directly inside your existing sturdy frame, preserving your interior trim and drywall. A full-frame replacement removes the entire window unit down to the rough opening, allowing us to inspect framing, replace rotted wood, and upgrade insulation and exterior flashing.

Do you handle permits for window installations in Loveland?

Yes. We navigate local building codes and handle the necessary permit requirements for your specific property in Loveland or surrounding Northern Colorado municipalities, ensuring your project is fully compliant from start to finish.

Can new windows be installed during the winter months?

Absolutely. While many homeowners wait for spring, our experienced installation team replaces windows efficiently during winter. We work room by room to minimize exposure to outdoor temperatures and seal each opening immediately so your home stays comfortable throughout the process.
