Air Sealing Services
Air sealing is one of the most effective ways to improve comfort, reduce drafts, and cut energy waste in Colorado homes. By sealing the hidden gaps and attic leaks that let conditioned air escape, your home stays warmer in winter, cooler in summer, and far more efficient all year long.
Colorado’s climate swings—from freezing winter nights to hot, dry summers—make air leakage a major source of discomfort and wasted energy. Attics in Denver-area homes are the #1 place where conditioned air escapes, leading to drafts, uneven temperatures, and higher heating and cooling bills.
Even better: Xcel Energy offers rebates for attic air sealing. If your home heats with natural gas, you may qualify for 30% to 60% back on your project. That means real savings up front and lower utility bills month after month.
Our air sealing services target the hidden attic gaps, bypasses, and penetrations that cause energy loss. By sealing these pathways, your home stays more comfortable and efficient all year long.

Why Air Sealing Matters
In Colorado
Cold upstairs bedrooms in winter. Hot second floors in summer. Rising energy bills even when your HVAC is running nonstop. In Colorado homes—especially around Denver, Colorado Springs, and the Front Range—these issues almost always start in the attic.
Air leaks around attic penetrations, light fixtures, top plates, duct connections, and chimneys allow conditioned air to escape and outdoor air to rush in. This creates drafts, uneven temperatures, and the “stack effect” that makes upper floors hard to heat or cool.
By sealing these hidden gaps and tightening your home’s envelope, your home holds temperature better, reduces energy loss, and stays far more comfortable year-round.
If your attic also needs insulation, pairing both services together provides the highest efficiency gains—especially in our high-altitude, rapidly changing Colorado climate.
Benefits of Air Sealing
Lower Energy Bills
Air sealing prevents heated and cooled air from escaping through attic gaps and bypasses. With less energy loss, your HVAC system doesn’t run as often — and your monthly utility bills reflect the savings.
Year-Round Comfort
Eliminate drafts, cold floors, and hot upstairs rooms. By sealing the hidden pathways where outdoor air enters your home, temperatures stay more consistent across every level — even during Colorado’s harshest winter nights and hottest summer days.
Improved & Cleaner Indoor Air
Proper air sealing helps reduce the flow of dust, allergens, and outdoor pollutants entering your home through attic leaks. This creates a cleaner, more controlled indoor environment across all seasons.
Colorado Home Rebate Savings
Many Xcel Energy customers qualify for 30%–60% rebates when pairing attic air sealing with insulation improvements. Colorado Home Services handles the paperwork so you receive every rebate dollar available.
Our Air Sealing & Insulation Process
Attic Inspection & Testing
We begin with a comprehensive evaluation that includes a blower door test and thermal imaging scan to reveal hidden air leaks throughout your attic and upper floors. We also measure your current insulation depth and identify common Colorado problem areas such as attic bypasses, open chases, recessed lighting gaps, and rim-joist leakage.
Air Sealing Services
Next, we seal the major pathways where conditioned air escapes. This includes gaps around light fixtures, attic hatches, top plates, duct connections, plumbing penetrations, and other attic bypasses commonly found in Denver-area homes. Proper air sealing reduces drafts, uneven temperatures, and overall energy loss.
Attic Insulation Recommendations (If Needed)
After your attic is professionally air sealed, we evaluate whether additional insulation would improve comfort and efficiency. If your home is below the recommended Colorado R-value, we’ll provide clear guidance and next steps. Proper insulation works best after air leaks are sealed, so pairing both services can deliver the highest results in Colorado’s extreme climate. If insulation is recommended, we can also help with that.
Colorado Home Energy Rebate Support
If your home heats with Xcel Energy natural gas, you may qualify for 30%–60% back on your project. Colorado Home Services manages the entire rebate process, ensuring you receive every dollar available for your air sealing and insulation improvements..
Final Home Check & Cleanup
We re-test after the work is completed to verify measurable improvements in air leakage and insulation performance. Then we tidy your attic from top to bottom; leaving your home cleaner, safer, and more efficient than we found it.
Have An Older Or Larger Home In Colorado?
Look For Signs You Need Upgraded Attic Insulation and Air Sealing Services
Room Temperature Changes
If certain rooms never feel the same temperature as the rest of the home, especially upstairs bedrooms or bonus rooms, you’re likely losing conditioned air through attic leaks. Air sealing helps restore even, consistent comfort.
Cold Floors and Hot Upper Levels
Cold floors in winter? Overheated second floors in summer? This is a classic sign of the stack effect, where warm air escapes through attic gaps and pulls cold air in from below. Sealing those escape points makes a huge difference in Colorado homes.
Drafty Doors or Hallways Near The Attic
Feeling a breeze near your attic access, hallway, or by interior door frames? That usually means attic bypasses are letting outdoor air move through your home. Air sealing closes these hidden pathways.
Heating & Cooling Bills Keep Climbing
If your energy bills rise faster than the temperatures outside, your home may be losing heat or AC through attic penetrations. Sealing leaks reduces HVAC strain and often lowers monthly utility costs — even more when paired with insulation, if needed.
If any of these sound familiar, schedule an attic inspection.
We’ll identify the exact air leaks affecting your home and let you know whether insulation upgrades would help as well.
Signs Your Home Needs Air Sealing
Older Colorado homes — and even many newer ones — often have hidden attic air leaks that cause drafts, uneven temperatures, and rising energy bills. If you’re experiencing any of the issues below, it’s likely your attic needs professional air sealing, and possibly insulation upgrades depending on your R-value.
