Did You Know?

Did you know that window replacements can significantly impact your energy bills? It’s a little-known fact that old, inefficient windows can contribute to heat loss and air leakage, leading to higher heating and cooling costs.

Replacing your windows with energy-efficient options can improve your home’s insulation and reduce energy waste. Modern windows are designed with advanced technologies like double or triple glazing, low-emissivity coatings, and insulating gas fills, which help to keep the heat in during winter and block out the heat during summer. This translates to lower energy consumption and, ultimately, savings on your utility bills.

Additionally, new windows often come with improved sealing mechanisms that prevent drafts and air leakage. This enhances your comfort by reducing cold spots and drafts and helps maintain a consistent indoor temperature throughout the year.

So, if you’ve been on the fence about window replacements, consider the hidden benefits they offer. By upgrading to energy-efficient windows, you can not only enhance the beauty and functionality of your home but also save money on your energy bills in the long run. It’s a wise investment that pays off both comfort and cost savings.

Exploring window Styles:
finding the perfect match for your home

When it comes to windows, there are many styles to choose from. Each one comes with its own purpose and look. So, if you are considering new windows, it’s important to understand the different styles you can choose from. Here are a few of the options for your Fort Collins window replacement:

Double-Hung Windows:

Double-hung windows have a window sash on the top and the bottom that can move. This means you can open the window from the top or the bottom. They are great for ventilation and easy to clean.

Single-Hung Windows:

Single-hung windows look similar to their double-hung counterparts on the surface. However, rather than opening from the top and the bottom, only the bottom is operable, leaving the top fixed.

Slider Windows:

Slider windows slide back and forth, similar to a sliding glass door. They are easy to use and let in a good amount of light. They are great for smaller areas where a swinging window couldn’t fit.

Awning Windows:

Awning windows open from the bottom and swing out from the top. They’re called “awning” because they resemble an awning when open. This design allows them to remain open during light rain.

Bay and Bow Windows:

These windows stick out from your wall. Bay windows have three parts, while bow windows often have many more. They make the room larger by creating additional interior space.

Custom Windows:

Custom windows are the solution to replacing current windows with a unique shape or adding something that fits your home perfectly. You can design windows to match your style perfectly.

Frequently Asked Questions About Replacing Windows in Fort Collins

How do I prepare my house for replacement windows?

You can help the process go smoothly by removing all window treatments, such as blinds or curtains, and clearing a path for the installers. Moving furniture away from the windows and taking down fragile items from nearby walls ensures our team has safe access to the work area.

What should I consider when installing new windows?

It is important to evaluate the thermal performance and structural integrity of the window based on your specific climate. In Fort Collins, focusing on the U-factor and Solar Heat Gain Coefficient is essential for managing high-altitude sun and rapid temperature swings.

Can I install new windows myself?

While a DIY approach is possible for some, professional installation ensures the window is perfectly level and properly flashed to prevent leaks. Custom Exteriors provides the specialized tools and experience necessary to maintain the manufacturer’s warranty and ensure a weather-tight seal.

Is it worth replacing 20-year-old windows?

Yes, windows from two decades ago often suffer from seal failure and lack the advanced Low-E coatings found in modern units. Upgrading can improve your home’s energy efficiency by 15% to 30% while eliminating drafts and increasing property value.

How much does it cost to replace a window on average?

A standard professional window installation in Fort Collins typically ranges between $800 and $1,800 per unit. This investment depends on the frame material, the glass package selected, and the complexity of the specific opening.

Is it worth replacing 20-year-old windows?

Yes. Modern windows from brands like Milgard, Pella, and Anlin are significantly more energy-efficient than those built two decades ago. Replacing old windows can reduce your heating and cooling costs while eliminating drafts and improving home security.

Who has the best windows for the money?

Anlin and Pella are two of the window manufacturers considered the best options for balancing cost and performance. Anlin offers exceptional value for Western climates, while Pella provides a diverse range of durable materials like fiberglass and wood-clad options.

What is the downside of vinyl windows?

Lower-grade vinyl can expand and contract significantly during extreme temperature shifts, which may lead to seal failure over time. We use premium, reinforced vinyl options that are specifically engineered to resist warping and fading in high-UV environments.

Which is better, vinyl or PVC windows?

Vinyl windows are actually made from a specific type of PVC called uPVC. The quality depends on the additives used in the manufacturing process; premium vinyl is designed to be more rigid and weather-resistant than standard utility-grade PVC.

Do new windows help with outside noise reduction?

Modern double and triple-pane windows act as an effective sound barrier against traffic and neighborhood noise. Options like the Anlin Del Mar series feature specialized glass thicknesses that significantly dampen exterior sounds for a quieter indoor environment.

Will new windows increase my home’s resale value?

Window replacement is consistently ranked as one of the top home improvements for return on investment. Prospective buyers value the improved curb appeal, reduced maintenance, and lower utility costs associated with high-performance windows.

Can I change the size or style of my windows during replacement?

We can often modify the existing opening to accommodate a different style, such as converting a sliding window into a casement or a picture window. Our full-service team handles the necessary structural adjustments and exterior finish work to ensure a seamless transition.
