Floors that feel cold underfoot

What crawl space insulation does for your house
Crawl space insulation in Corona, CA seals the air leaks under your house and insulates either the crawl space walls or the floor above them, so the rooms over it stop losing heat and the floors stop feeling cold.
If a room over the crawl space is cold under your socks all winter, or the power bill jumps every time the heat runs, the first question is what's actually down there. The price mostly moves with the size of the crawl space, whether we insulate the walls or the floor, foam or batts, and how many gaps around pipes and wires need sealing. The schedule turns on what we find first, because mold, old wraps on pipes and ducts, or a permit can come ahead of the insulation. I come out, crawl in and look, and your number comes from that visit, not a guess over the phone.
One lead installer runs your job
I come out to look and write up the estimate, then our installers do the work with a lead installer running the job, so one person on site knows the plan.
Fully licensed and insured
California has a contractor license class for insulation work, so it's fair to ask anyone you hire about their license. We're fully licensed and insured, and happy to answer that.
You'll understand what we did
When we finish, we walk you through what went in and why, plainly enough that you could explain it to the next person who works on your house.
How we insulate a crawl space
I start under the house with a flashlight, because whether we insulate the crawl space walls or the floor above depends on what's actually down there, like the vents, any damp spots, where the ducts and pipes run and how old the place is. If I find mold, old wraps on pipes or ducts, or a gas appliance that relies on the vents for air, we stop and sort that out with you before anyone insulates anything. Once the plan's set, our lead installer and crew seal the holes where plumbing and wiring pass through the subfloor, so the new insulation isn't fighting a draft. Then they fit batts snug between the joists with no gaps or squashed spots, use spray foam where it makes more sense, or seal and insulate the walls if that's the route, and clean up before they leave.
A crawl space rarely leaks alone. If the floor is drafty, the attic hatch, outlets and plumbing gaps upstairs usually are too, and air sealing services close those gaps so the house holds the air you paid to heat or cool. When a room stays chilly after the floor is done, I look at the outside walls next, since thin or empty walls are a job for wall insulation.
When crawl space insulation is worth a look
One room that won't keep up
A bedroom that never matches the thermostat is the kind of puzzle we like. Sometimes the answer is under the floor and sometimes it isn't, and we'll tell you which.
Ducts and pipes under the house
When heating and cooling ducts run through the crawl space, they can lose heat before the air reaches your rooms, so where they run shapes whether we insulate the walls or the floor.
Rentals and small buildings
Landlords call us when tenants complain about cold floors or high bills. We look at the crawl space, fix what's causing it and explain the work so you can pass it along.

Crawl space insulation questions from Corona homeowners
Here are the questions I hear most when I'm under a house in Corona, answered the way I'd answer them in your driveway.
How much does crawl space insulation cost in Corona?
Insulating a crawl space in the Riverside-San Bernardino area usually runs about $1,600 to $7,000 per job. That's the going range in the area, not our price. Where yours lands depends mostly on what I find down there and which route makes sense. I'll give you your own number after I've looked.
Is there help paying for energy upgrades in Riverside County?
Yes, Riverside County residents may qualify for free energy efficiency upgrades through the weatherization program at Community Action Partnership of Riverside County, which aims to lower monthly utility bills. Households with income before taxes at or below 60% of the state median income may be eligible. It's worth checking with them before you book anything.
Should I insulate the crawl space walls or the floor above?
Usually the walls, because sealing and insulating them ties the crawl space to the house, which is good practice in any climate. In some homes the floor above works better as the line. One insulation maker's guide says that in an unvented crawl space, insulating the walls means pipes and ducts don't need their own insulation. I make the call once I've seen it.
Can I just seal off my crawl space vents?
No, closing the vents by themselves can make the crawl space damper. If a gas furnace or water heater down there relies on those vents for air, that shortcut can turn deadly. Turning a vented crawl space into a sealed one takes a plan that handles the moisture and any gas appliances, and that's what we work out with you first.
What if there's mold or old pipe wrap in my crawl space?
Mold or old pipe wrap gets dealt with before any insulation goes in. Surface mold calls for a certified mold remediation expert to inspect and set a cleanup plan, and old wraps on pipes and ducts in older homes may contain asbestos, which a certified abatement firm inspects. Plan on that cleanup as its own step ahead of the insulation.
Do I need a permit to insulate a crawl space in Corona?
The City of Corona requires a building permit before work starts to alter, repair or improve any building, so we check with the city before your job starts. California's Energy Code also sets efficiency rules for alterations to existing homes. Some areas we work in fall under the county instead, and if a permit is needed we handle the application and meet the inspector.
