WHAT IS THE BEST WAY TO COMPARE WINDOWS?

The only accurate method to compare windows is to look at the NFRC rating for each one you are thinking about. NFRC labels that have received independent accreditation rate the general window performance using the U-Factor and Solar Heat Gain Coefficient (SHGC). The lower these ratings are, the better the window will perform. U-Factor or SHGC should be prioritized based on your climate. Regardless of the sales pitch, you should choose the NFRC ratings that are optimal for your environment and your financial situation.

Does The Window Store install ENERGY STAR® windows and patio doors?

Yes – Any window or patio door ordered with a Low E glass upgrade must meet the ENERGY STAR® standards for the climate zone. This promise is always offered in writing on your contract paperwork to ensure that you order and receive the best Low E glass that is suited to your particular temperature zone.

Are there tax credits available when replacing windows and doors?

With our ENERGY STAR® products — yes! A 10% federal tax credit worth up to $200 for windows and $500 for patio doors that adhere to ENERGY STAR® standards may be available to you. These tax credits were set to expire in 2011, however a new law called "The American Taxpayer Relief Act of 2022" extended them into 2023 and retroactively to 2022.

How can The Window Source be so much more affordable than their competitors?

The Window Source can provide you with high-quality vinyl windows at a very affordable price because of our wide national purchasing power. Our low pricing and straightforward purchase procedure also enable us to operate at a high level of efficiency and pass the savings on to you.

Is the installation process as important as the window product itself?

A window needs to be accurately measured to suit the opening and leave space for plumbing and squaring the new window. No matter how high the quality of the new window, if it is not squared and correctly plumbed, it will not seal and function well.

10 Warning Signs Your Windows Are Failing in Mankato

If you’ve been noticing small issues around your home, then you may be thinking of changing it, but does it really need to? Sometimes it’s obvious, like drafts or sticky windows, but other times the signs are subtle.

Knowing when to replace your windows can make a big difference for your comfort, energy bills, and even your home’s appearance. Acting early with the right window replacement helps you replace your windows before small problems turn into bigger ones.

In this guide, we’ll break down the 10 Clear Signs You Need New Windows in Mankato, explain why they matter, and show how upgrading your windows can make your home feel warmer, quieter, and more energy-efficient.

Top 10 Signs Your Windows Need Replacing

When you see 10 Signs It’s Time To Replace Your Windows, you’ll know your home needs care. In Mankato’s seasons of hot summer sun and cold winters, it matters more. Good replacement window choices, whether double hung windows, sliding windows, or casement & awning windows, can save energy, cut noise, and lift your home’s look.

If windows are foggy, drafty, or sticking, they may be failing. As The Window Source of Mankato would say, timely upgrades bring real comfort and value.

1. Drafts and Air Leakage

Feeling a breeze near your windows even when they’re closed is one of the 10 clear signs you need new windows in Mankato. Drafty windows allow warm or cool air to escape, forcing your heating or cooling system to work harder.

This sign that you need new windows can affect comfort and energy bills. Older windows, especially single-pane or worn double-hung windows, often fail to seal correctly over time. Signs to look for:

Cold air near window frames or sashes
Uneven room temperatures
Windows that rattle slightly in the wind
Rising energy costs without other reasons

Acting on this issue with window replacement ensures your home stays cozy and keeps your home energy-efficient year-round.

2. Difficulty Opening or Closing

If your windows stick, jam, or feel heavy, it may be time to replace your windows. Sticking often happens when the window frame warps, hardware wears out, or sash components fail. Trying to force a stuck window can cause more damage. Windows need replacing when they consistently resist movement. Signs to look:

Sashes that don’t slide smoothly
Windows that tilt or jam in tracks
Locks or latches that won’t engage
Frames that feel warped or uneven

Replacing these windows with a replacement window improves functionality and safety, letting you enter your home comfortably every time.

3. Condensation Between Panes

Fog or moisture trapped between panes signals a broken seal in your double- or triple-pane windows. The insulating gas escapes, reducing energy efficiency and causing temperature fluctuations. This sign that your windows need replacing indicates that your current windows aren’t performing their job. Signs to look:

Foggy or hazy glass between panes
Frost forming inside during winter
Moisture accumulation between windows and doors
Windows that feel colder than the surrounding areas

A well-sealed replacement window featuring Energy Saving Glass restores insulation and helps keep your home comfortable while protecting against water damage.

4. Rising Energy Bills

Unexpected increases in heating or cooling costs are another sign you need to replace your windows. Older windows, worn seals, or single-pane designs let heat escape in winter and enter in summer. Energy-efficient vinyl windows or modern triple-pane options can save money while keeping your home cozy. Signs to look:

Higher than usual energy bills
Rooms that never reach a comfortable temperature
Cold or hot spots around windows
Windows that feel unusually cold or warm

Choosing replacement windows improves insulation and helps windows function better for long-term comfort and efficiency.

5. Outside Noise Getting Inside

If you notice increased outside noise, like traffic or neighborhood sounds, your windows aren’t blocking sound properly anymore. Modern energy-efficient windows with double or triple panes and tighter seals reduce noise and make your home more peaceful. Signs to look:

Loud sounds from the streets or neighbors
Windows that rattle in windy conditions
Difficulty hearing inside conversations
Noticeable difference compared to new or upgraded windows

Replacing your windows not only improves comfort, but also windows can improve your home’s overall quality of life.

6. Visible Damage or Rot

Cracked glass, rotting frames, and warped window sashes are clear signs your windows need replacing. Damage invites leaks, drafts, and even pests. Ignoring older windows that show wear will only worsen the problem. Signs to look:

Cracks, chips, or broken glass
Rotting or soft window frames
Warped sashes or bent tracks
Peeling paint or rusted hardware

Investing in a replacement window protects your home and ensures that windows last longer, avoiding costly repairs later.

7. Fading Furniture or Floors

Sunlight fading your furniture or flooring is a subtle sign that you need new windows. Older or single-pane windows may lack windows with UV-blocking technology. Modern low-E windows reduce fading while maintaining temperature control. Signs to look:

Sun-bleached carpets, curtains, or furniture
Hot spots near windows during summer
Windows that feel hotter than the room
Fading paint or finishes near sunlight

Replacing your windows with options offering excellent Color & Style Options helps protect interiors and allows windows to improve your home’s energy efficiency.

8. Worsening Allergies

Old windows with failing seals let pollen and dust enter, which can worsen allergies. If you notice sneezing or irritation near windows in your home, it’s a sign that your windows need replacing. New vinyl windows and tight-fitting frames reduce allergens and improve indoor air quality. Signs to look:

Sneezing or watery eyes near windows
Dust accumulation around window sills
Drafty windows allowing pollen entry
Inconsistent indoor humidity

A proper window replacement creates a healthier home and helps keep your home allergen-free.

9. Windows Over 15–20 Years Old

Most home windows last 15–20 years. After that, seals and frames weaken, even if the windows look fine. If your windows are older windows, they may need to be replaced sooner. Age alone is a strong sign that you need to replace your windows before serious failures occur. Signs to look:

Windows that were installed 15–20 years ago
Frames showing signs of wear or sagging
Glass or seals are no longer effective
Outdated styles or hardware

Replacing older windows ensures that windows function properly, stay energy-efficient, and enhance home safety.

10. Poor Curb Appeal or Outdated Style

Windows define the look of your home. Old, faded, or mismatched windows pull down curb appeal. Updating with new styles, such as bay, bow & garden windows, or updated color and style options, is a simple way to enhance your home’s appearance and value. Signs to look:

Faded or chipped window frames
Mismatched window styles across the home
Windows that don’t complement the architecture
A home that looks outdated from the street

Modern replacement windows enhance your home’s look and function, making it more appealing and comfortable inside.
