What are the signs you need new windows? New window signs can be as apparent as the glass you are looking through, or sometimes a bit hazy (pun intended!)
Boise homeowners looking for new windows know our weather doesn’t play favorites. We get freezing mornings, blazing summer afternoons, and plenty of temperature swings in between all year long in the Treasure Valley. That combination beats up windows faster than most people realize, drying out seals, warping frames, and letting drafts sneak in where comfort used to live.
I’ve seen it all across the Treasure Valley — from East Boise bungalows to new homes in Meridian and Nampa — where perfect houses lose efficiency and comfort because of tired, outdated windows. The good news? The early warnings are easy to spot once you know what to look for.
Here are the eight signs you need new windows and why catching them early can save you thousands on energy costs and future home repairs.
8 Signs You Need New Windows in Boise
While Legacy Roofing specializes in roofs, we also help homeowners and businesses across the Boise and Treasure Valley regions with other exterior remodeling phases, including new windows! As one of the honest exterior pros in the area, we always keep it real!
Here are the top 8 reasons we see homeowners often need new windows! Of course, it is important to always have your windows inspected before ever agreeing to purchase new windows!
1. Drafts and Air Leaks Around the Frame
You never forget the first time you sit near a window in winter and feel a chill creep through the seams. It’s more than discomfort — it’s a sign your home is wasting energy. In Boise’s climate, where temperature swings are real, air leaks can make your heating and cooling systems work overtime. Poor installation, aging frames, or weather stripping that has given up are usually to blame.
A chilly breeze on your couch isn’t just an annoyance — it’s your home telling you it needs help. Will you wait for water stains to appear, or fix the problem before it spreads?
2. Rising Energy Costs
Sticker shock on your power bill? Check your windows before blaming the utility. Boise swings from hot to cold in a hurry. Weak seals and dated glass make your system run longer. That raises usage even when the weather feels the same. Single-pane units and poor sealing are common culprits. New weatherstripping helps a little, but failed seals require replacement.
If your bills are climbing and your thermostat never gets a break, that’s one of the clearest signs you need new windows.
3. Condensation Between the Glass Panes
Foggy glass doesn’t mean your home is cozy — it means your windows are failing. That cloudy layer between panes is proof the seal broke and outside air crept inside. Once the insulating gas leaks out, your window no longer does its job. Heat transfer rises, comfort falls, and the view from your living room blurs into a haze.
No cleaner can fix this permanently — only new glass units or full window replacement will bring back clear views and comfort.
4. Difficulty Opening or Closing Windows
If opening your window feels like an upper-body workout, that’s not strength training — it’s a warning. Swelling from moisture, warped wood, or bent tracks often lie behind the resistance. Even vinyl frames can twist in Boise’s wide temperature ranges. When they jam, they’re not just inconvenient — they’re unsafe. A stuck window can block an emergency exit.
If lubrication or sanding doesn’t help, the structure itself may be compromised. That’s when replacement makes the most sense.
5. Noticeable Outside Noise Indoors
Boise isn’t New York City, but that doesn’t mean you should hear traffic or lawnmowers like they’re in your living room. If outside noise is creeping in, your windows likely lost their insulation. Older single-pane windows and worn seals allow sound to travel freely.
Replacing them with double-pane or laminated glass units reduces both noise and energy loss. The peace and quiet you gain are instant proof that new windows make a real difference.
6. Visible Damage to Frames or Glass
Cracked panes, peeling paint, or soft window sills are red flags. Boise’s mix of dry summers and snowy winters expands and contracts window materials, eventually breaking seals and rotting frames. Once rot sets in, it spreads quickly. A small crack today becomes a bigger repair tomorrow.
If the frame feels soft when you press it or you notice cloudy glass and gaps, it’s time for more than a quick touch-up — it’s time for replacement.
7. Outdated Appearance That Hurts Curb Appeal
Curb appeal matters, especially in competitive Boise neighborhoods. Yellowed vinyl, dated grids, or bulky frames can make your home look older than it is. Modern windows with slim profiles and color-stable finishes instantly refresh your exterior and tie together your roof, trim, and siding.
At Legacy Roofing Idaho, we often replace both roofs and windows together — ensuring everything matches, seals properly, and boosts your home’s long-term value.
8. Trouble Maintaining Comfortable Indoor Temperatures
If one room always feels colder or hotter than the rest, your windows are likely the culprit. Old or inefficient glass lets conditioned air escape and outdoor air rush in. Boise’s summer heat and winter chill expose that weakness fast.
When your HVAC system can’t keep up, you’re paying more for less comfort. New energy-efficient windows help regulate temperature evenly throughout the house — and reduce strain on your heating and cooling system.
Why It Matters for Boise Homeowners
Boise’s four-season climate is harsh on building materials. Between high-altitude UV exposure, winter ice, and dry winds, even premium windows wear out faster here than in milder regions. That’s why catching these signs you need new windows early pays off — both in comfort and long-term savings.
If you’re noticing drafts, condensation, or rising energy bills, it might be time for a professional inspection. Legacy Roofing Idaho doesn’t just handle roofs — we also specialize in window replacement designed for the Treasure Valley’s unique weather conditions.
We’ll walk you through your options, explain energy ratings, and match your new windows to your home’s existing style and roofline.

1. How much do new windows cost in Boise?
For most Treasure Valley homes, window replacement costs range between $700 and $1,200 per window installed, depending on size, style, and energy rating. Vinyl windows are the most affordable and popular, while fiberglass or composite options offer better durability and insulation. At Legacy Roofing Idaho, our estimates always include labor, materials, disposal of your old windows, and clean-up — no surprise add-ons. You’ll get a transparent, itemized quote before any work begins.
2. What types of windows work best for Boise’s climate?
Boise’s hot summers and cold winters call for double-pane or triple-pane Low-E glass with insulated vinyl or fiberglass frames. These materials hold up well against UV exposure, temperature swings, and occasional snow loads. Casement, slider, and picture windows are common in newer Boise homes, while older properties often benefit from replacing single-hung or wood units with more efficient models. We help you select windows built specifically for Idaho’s four-season conditions.
3. How long do new windows typically last?
Modern, high-quality windows in Boise usually last 20 to 30 years with proper installation and minimal maintenance. Factors like exposure, frame material, and seal integrity play a role. For instance, vinyl frames resist moisture and fading, while fiberglass provides added strength in extreme heat or cold. At Legacy Roofing Idaho, we only install windows that meet Energy Star® standards and include strong manufacturer warranties to protect your investment long-term.
4. Can I replace my windows and roof at the same time?
Absolutely — and in many cases, it’s the smartest move. Coordinating your window and roof replacement allows us to ensure proper flashing, insulation, and color matching across your exterior. It also saves you money on labor and project management since crews and materials overlap. Many Boise homeowners upgrade both at once for maximum energy efficiency, consistent curb appeal, and long-term protection against Idaho’s unpredictable weather.
