Understanding Drafty Windows in Longmont, CO
If you are experiencing drafty windows in your Longmont home, you are not alone. This is one of the most common Windows issues reported by homeowners in the 80501 area, and it often signals a problem that requires professional attention.
Drafty windows let conditioned air escape and outside air in — raising your energy bills and reducing comfort. While weatherstripping helps temporarily, drafty windows usually need professional repair or replacement.

Professional Windows Tips & Advice
A window's U-factor matters more than the brand name. Focus on U-factor 0.30 or lower for your climate zone — that's the number that determines how much heat escapes your home.
When getting quotes, make sure installation includes removing the old frame down to the rough opening. "Pocket" installations that fit new sashes into old frames save money upfront but reduce performance.

What to Expect from Window Replacement in Longmont
A detailed guide to professional window replacement service in the Longmont, CO area.
The installation process for a single replacement window takes 30-60 minutes in skilled hands. The old window is removed, the opening is cleaned and inspected, the new window is set and shimmed for perfect squareness, fastened securely, insulated around the perimeter with low-expansion foam, and sealed with exterior-grade caulking. Proper installation is as important as the window itself — even the best windows underperform if installed incorrectly.
For CO's varied terrain and weather climate, window energy performance matters significantly. Look for these specifications: a U-factor of 0.30 or lower (measures heat transfer), Solar Heat Gain Coefficient (SHGC) appropriate for your climate zone, and ENERGY STAR certification. Triple-pane windows with krypton gas fill represent the highest efficiency, while double-pane Low-E argon units offer the best value. Your Longmont installer can recommend the optimal configuration.
Common Windows Problems in Longmont
Experiencing one of these issues? Here is what is happening and what you should do about it.
“I can feel cold air coming through my windows”
Drafty windows mean the seal between the window and frame has failed, the weatherstripping is worn, or the window itself has lost its insulating gas fill. This directly increases your heating and cooling costs.
A window professional will assess whether the draft can be fixed with new weatherstripping and caulking, or if the window requires full replacement. Modern double or triple-pane windows with low-E coating dramatically reduce drafts and energy loss.
“There is condensation between my window panes”
Fog or moisture between double-pane glass means the sealed insulating gas unit has failed. Once the seal breaks, the insulating argon or krypton gas escapes and the window loses its energy efficiency.
Failed sealed glass units cannot be repaired, only replaced. Depending on the window age and condition, you may be able to replace just the glass unit (IGU) or it may be more cost-effective to replace the entire window.

Should You Repair or Replace? — Windows Decision Guide
Use this framework to make the right financial decision for your Longmont home.
🔧 Consider Repairing When...
- Only one or two windows are affected
- Hardware failure (locks, hinges) with intact glass
- Minor weatherstripping wear on newer windows
- Condensation on interior surface (humidity issue, not window failure)
🔄 Consider Replacing When...
- Condensation between glass panes (seal failure)
- Visible rot or decay in window frame
- Single-pane or original windows from before 1990
- Significant drafts despite weatherstripping
- Multiple windows showing same issues
- Energy bills disproportionately high for home size
If fog or condensation appears between double-pane glass, the seal has failed and the window must be replaced — there is no cost-effective repair for a failed insulated glass unit.
