What does attic air sealing do for a house in Sparks?
Attic air sealing in Sparks closes the gaps between your rooms and the attic, at the tops of walls and around pipes, wires and the hatch, so the air you pay to heat and cool stays in the house and the insulation above it can do its job.
Most people call because the upstairs runs hot, the room over the garage never feels right or the power bill keeps climbing, and the attic is usually where the air is getting out. The price moves with how big the attic is, how hard it is to get around in, how many openings need closing and whether old, soaked or dirty material has to come out first through insulation removal. The schedule mostly turns on what has to be fixed before sealing can start, like a roof leak or a bath fan venting into the attic, and I'll give you your own number once I've been up there with a flashlight.
How we do attic air sealing
Before anything gets sealed, I look at the gas appliances and how the house gets fresh air, and if there's a roof leak or a bath fan blowing into the attic, we sort that out first, because sealing over a problem only hides it. Then we pull the insulation back and go after the big openings, the tops of walls and the spaces behind kneewalls, since those move far more air than the small cracks. Large holes get solid blocking, hot flues get metal around them, can lights that aren't rated to touch insulation get covers, and the smaller gaps at pipes, wires and the hatch get foam or caulk. Soffit, ridge and gable vents and any duct feeding air to a furnace are meant to stay open, so we leave them clear, lay the insulation back evenly, edges included, and clean up. The work is backed by our satisfaction guarantee.
Once the gaps are closed, a lot of attics need more insulation on top, and retrofit insulation adds to what's already up there instead of starting over. Spray foam insulation seals and insulates in one pass but costs more, so I usually only point people to it when the ductwork lives in the attic.
What to know about attic air sealing in Sparks
The City of Sparks issues building permits, and its list names roofing, furnaces and moving or adding plumbing or electrical, but it doesn't mention attic air sealing, so whether your job needs one is a question for the city. Before work starts we check with the city or county office for your address, tell you what it asks for and take care of the permit when your job needs one.
A lot of attics we climb into around here haven't been touched in years, with can lights cut through the ceiling, bath fans dumping into the attic and old insulation pressed flat over the tops of walls. We see the same thing on jobs in Reno and Spanish Springs, and we handle it the same way, fixing what's wrong first and sealing second.

How much does attic air sealing cost in Sparks and Reno?
Weatherization work in the Reno area usually costs about $550 to $5,300 per project. Where your attic lands depends on its size, how easy it is to move around in, how many openings need closing and whether a leak or bath fan has to be fixed first. I'll give you a number for your own house after I've seen the attic.
How do I know if my attic is ready for air sealing?
Your attic is ready once the roof doesn't leak, bath fans vent outside instead of into the attic, and there's no active knob and tube wiring, the old kind strung on porcelain knobs, or vermiculite, the pebbly gray-brown loose fill. Those get fixed first, along with any unvented kerosene heater or gas fireplace in the house, because sealing around them hides a problem instead of solving it.
Is attic air sealing safe in a house with a gas furnace or water heater?
Yes, when the job includes a worst-case draft test before and after the work, which checks that fumes from anything burning fuel still leave the living space. The usual guidance is to repeat that test at the end of each workday when a job runs more than one day, so the house is safe every night. That's why I look at gas appliances and fresh air before anything gets sealed.
How do I know the attic air sealing worked?
A blower door test, a fan set in an outside doorway that pulls air out of the house, helps find leaks and confirm the sealing worked. Its main drawback is the fee you pay the home energy rater who runs it. The test can pull dirt and pollen inside and has been known to lift vinyl flooring that isn't glued down, so it's worth preparing those rooms.
Is a contractor with a Nevada license also licensed to work in Sparks?
Not necessarily, because a State of Nevada contractor license doesn't mean the contractor is also licensed in Sparks. Ask anyone you're thinking of hiring about both before work starts.
Can I air seal my own attic in Nevada?
You can, but an owner working on a home they live in, not one they'll sell or lease, has to apply to the Nevada State Contractors Board for a licensing exemption first. If you'd rather hand it off, I'm happy to walk the attic with you and explain what I'd seal and why.
