Why are my floors cold, and will insulating the crawl space help?
Crawl space insulation in Hampton means sealing the air leaks under your house and insulating either the crawl space walls or the floor above them, so the rooms over it stop pulling cold up through the boards and the wood underneath stays drier.
Most people call us about cold floors, a damp smell in the hallway or a power bill that climbs every winter, and the crawl space is usually where it starts. What the job costs turns on the size of the space, whether we insulate the walls or the floor, which material goes in, and whether there's wet wood, pest damage or old insulation that has to come out first. The schedule turns on those same repairs and on a permit if the city calls for one, which we'd handle. I'll look at it with you, go over what I find, and write it up so you can see your own figure before you decide anything.
How we handle crawl space insulation, start to finish
Closing up a vented crawl space is a bigger decision than it looks, so I start by checking for water getting in, pest damage, and any gas or oil equipment down there. That equipment matters because a furnace or water heater that vents on its own draft can turn dangerous if the space around it gets sealed tight, so we plan around it before anything gets closed. If I find problems, you get a list, and those get fixed before any insulation goes in, since insulation over a leak or a chewed-up joist just hides it. Then our crew does the air sealing, which means closing the gaps around pipes, wires and the wood edge the floor sits on, and insulates the walls or the floor, whichever we agreed fits your house.
Crawl space work often ties into the rest of the house. If the rooms still feel drafty once the floor's done, the leaks are usually higher up, and our air sealing services go after them room by room. Cold outside walls are their own job, and wall insulation is where we'd look next.
Insulating the crawl space walls
This suits most houses, especially when ducts or water lines run under the floor, because sealing and insulating the walls brings the crawl space inside the house and keeps those lines in milder air. Most codes want a fire barrier, usually drywall, over foam on those walls, so we build that cover into the plan from the start.
Insulating the floor above
This suits a space that stays vented and dry with no ducts or equipment underneath, because the floor becomes the line between your house and the outside air. The insulation has to sit tight against the underside of the floor with the gaps sealed, or the cold just runs around it.
Crawl space insulation in Hampton: permits and what we find under houses here
Hampton's Development Services Center handles permits for the city, so I check with that office for your address before we start. When a permit's required, we apply for it as the contractor and set up the inspections. If you'd rather look into it yourself, you can register online for permitting and inspections, call 757-727-8311, or turn in a paper application at the office on the third floor of City Hall downtown.
Under a lot of older houses here we find vented crawl spaces with fiberglass batts that have dropped out of the joists, ducts running underneath and a plastic ground cover that's torn or missing. We see the same thing on jobs in Newport News and Poquoson, so the first visit is mostly about how wet the space gets before anyone talks about material. We're based in Hampton and work in the cities around it, and if you don't see yours on this site, give us a call and ask.
Why Hampton homeowners call A&J Hampton Insulation and Spray Foam about their crawl space
The owner looks underneath first
I come out myself to look at your crawl space and write the estimate, and our lead installer runs the crew while I check in during the job. The person who told you what the job needs is the one making sure it gets done that way.
Based in Hampton since 2017
We've been insulating homes from right here in Hampton since 2017, and most people call us to understand their crawl space before they spend money on it. I'd rather lay out the walls-or-floor choice and let you pick than push you into foam you don't need.
Licensed and insured on every job
We're licensed and fully insured, and that holds whether the job is a small floor or a full crawl space. It means the risk of the work sits with us and not with you.

Call or send a request
Call (757) 367-8752 or use the form, and we'll get back to you to set a time that works. Let us know whether the crawl space door is outside or inside a closet, so I know where to start.
I look underneath with you
I go into the crawl space and walk you through what I found, including any water, pest damage or equipment that changes the plan. Then I write it up so you can see what's included and what moves the price before you decide.
Repairs and permit come first
Anything that has to be fixed gets done before we insulate, so nothing new goes over a problem. If the city calls for a permit, we take care of it and set up the inspections.
Our crew does the work
Our lead installer runs the crew that seals and insulates the space while I check in along the way. At the end they walk you through what's down there before they pack up.
Frequently asked questions
What is the best way to insulate a crawl space, the walls or the floor?
For most houses the walls are the better choice, because building guidance treats sealing and insulating the crawl space walls as best practice, and it ties the crawl space to the rest of the house. Sometimes the floor above works as the insulated layer instead, and I'll tell you which fits once I've seen the space.
Can I just seal my crawl space vents?
Not on their own, because sealing the vents without a plan can raise the moisture down there. In warm, humid weather a vented crawl space usually takes on moisture that condenses on the cooler floor framing and leads to mold and rotting wood, but a closed space always needs a way to dry out. One of the better ways is letting a little conditioned air from your heating and cooling system into it, along with the equipment check we do before anything gets closed.
How much does crawl space insulation cost in Hampton?
Across the US, insulating a crawl space usually costs about $3 to $6 per square foot, and that's a national figure, not our price. Your number depends on the size of the space, walls versus floor, the material and any repairs that come first, and the estimate I write up gives you your own figure.
How long does crawl space insulation take?
The insulating is usually the quicker part, and most of the time goes into whatever has to be fixed first, like a leak, pest damage or changes around gas equipment. A permit can add a wait too, so I'll give you a sense of the schedule at the estimate once I've seen what's under there.
Do I have to leave the house while you insulate the crawl space?
Usually not with board or batts, since the work stays under the house. With spray foam, the foam maker sets a re-entry time, the wait before you can come back inside, and we tell you that before the job so you can plan for the kids and pets.
Who can do crawl space insulation work in Virginia?
In Virginia, a business that works on someone else's property needs a license from the state Board for Contractors, and its class sets how big a job it can take on while its specialty sets the type of work. A Class C contractor, for example, can take single jobs over $1,000 but under $30,000, with less than $250,000 of that work in any 12-month stretch, so compare your contract total with the class the contractor holds.
Other work that often goes with a crawl space job
Air sealing services
When the drafts come from outlets, the attic hatch and window trim rather than the floor, sealing those gaps is the fix.
Wall insulation
If your outside walls feel cold to the touch in winter, insulating them covers the part of the house a crawl space job can't reach.
