Window replacement in Littleton, measured right
Precise Windows LLC replaces drafty and hard-to-open windows for Littleton homes in every style, from double-hung to specialty shapes. We measure at your house and seal the new window in tight.
Precise Windows LLC installs replacement and new-construction windows for homes throughout Littleton, Colorado, in double-hung, casement, sliding, bay and bow, picture, awning, and specialty shapes. Every job starts with a measurement at your home, then an order from Andersen, Milgard, Pella, Prime, or Simonton, and an install that seals the opening tight. Littleton homeowners bring us windows that are hard to open, letting in noise, or simply original to the house.
Why do my Littleton windows feel drafty even when they're closed?
Cold air moving in around the sash usually points to weatherstripping that's worn thin or gone missing, since that's the piece sealing the moving part of the window against the frame, and it wears out long before the glass does. Sometimes the draft only shows up on windy days, which points to a gap that only opens under wind pressure, from a warped sash or a frame that's settled slightly. We check the weatherstripping on all four sides and the frame's fit before deciding whether it's a hardware fix or a sign the whole window's due.
Signs a Littleton window needs more than a quick fix
Draft that only shows up in the wind
A window that feels fine on a calm day but drafty when it's windy usually has a small gap that only lets air through under pressure. That's most often worn weatherstripping or a frame that's settled slightly out of square.
A sash that won't stay up on its own
A window that won't hold itself open has a worn balance or spring inside the frame, which is a hardware problem rather than a sign the whole unit's failing. On a bedroom window, that's also an emergency-exit issue worth fixing soon.
Outside noise coming through clearly
Single-pane glass with no air gap does very little to block sound, which is why older windows let in far more noise than a modern insulated unit. It's the same upgrade that helps with drafts and energy loss too.
What's causing it
Weatherstripping past its life
Weatherstripping compresses and tears with years of opening and closing, and once it's worn thin, air moves right through the gap it used to seal.
Single-pane or older insulated glass
Glass without a modern insulated unit lets cold and noise straight through, since there's no air gap or gas fill doing the insulating work.
A frame that's settled out of square
Houses shift over the years, and a frame that's settled even slightly can open a gap that only shows up under wind pressure or temperature swings.
What Colorado's energy code means for Littleton window replacement
Colorado's HB19-1260 requires local governments that update their building code to adopt one of the three newest versions of the International Energy Conservation Code, and HB22-1362 set the statewide floor at the 2021 IECC. The U.S. Department of Energy's Building America Solution Center lists the 2021 IECC prescriptive window U-factor limit for climate zone 5, which covers the Denver metro, at 0.30, though a city can adopt a stricter local amendment, so the figure that applies depends on what Littleton has adopted.
That code exists because older, drafty windows lose more heat than the current standard allows. On top of that, the EPA notes UV intensity rises about 6 percent per kilometer of elevation, and Front Range homes sit roughly a mile up, so seals and weatherstripping age faster here than they would at sea level.
We install replacement windows the same way in Englewood, Greenwood Village, and Highlands Ranch.
What we check during a Littleton window replacement visit
We test the weatherstripping and hardware on every window you flag, and check whether the draft's coming from the seal, the sash, or the frame itself. If it's a hardware issue, we can often adjust or replace it without touching the window. If the frame or glass has reached the end of its life, we measure the opening and walk through window options that fit the house and the budget.
What happens if you wait on drafty windows
Weatherstripping doesn't recover on its own, it keeps compressing and tearing until the gap gets bigger every season. A frame that's settled slightly tends to shift further rather than settle back into place. The longer a draft goes unaddressed, the harder your heating system works through a Colorado winter to make up for it.
Can Precise Windows fix a draft without replacing the whole window in Littleton?
Often, yes. If the draft's coming from worn weatherstripping or hardware rather than the glass or frame itself, we can adjust or replace those parts without a full window swap. We check the specific cause on the visit before recommending repair over replacement.
