Your attic is the single biggest source of heat loss in most homes. Proper insulation keeps warmth in during winter and heat out in summer.

Older attic with uneven coverage? Blown-in material fills every corner and gap, reaching the recommended R-value your home has likely never had.

Cold floors, drafty rooms, high bills - these are symptoms. A whole-home insulation assessment finds where your house is losing energy and fixes it.

Moisture-damaged or mold-contaminated insulation has to come out before new material goes in. We handle safe removal and disposal.

An open crawl space pulls cold air and moisture up into your floors all winter. Insulating it is one of the highest-impact upgrades a Charleston homeowner can make.

Drafts near outlets and cold exterior walls are not just uncomfortable - they mean warm air is escaping. Wall insulation stops that heat loss at the source.

Insulation slows heat. Air sealing stops it from escaping entirely. Both are needed - and most older Charleston homes have neither done properly.
Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home and what is prompting your call - age of the home, the area of concern, whether you have noticed specific problems. We respond within 1 business day, and most scheduling happens within the week.
A contractor comes to your home and physically looks at the attic, crawl space, or walls. We measure what is there, check for moisture issues, and explain what we see in plain language. No phone estimates - we give you a written quote after seeing the actual conditions. You have no obligation after this visit.
Once you approve the estimate, we schedule the work. Most jobs are completed in a single day. Before we leave, we walk you through what was done, show you the finished coverage, and give you documentation of the work. You can confirm everything yourself - no guessing.
We hold a valid contractor license through the West Virginia Division of Labor. You can verify it before you sign anything. Every job is fully insured, so you are protected if anything goes sideways - no exceptions.
We are a local business, not a franchise or out-of-state company. Our team knows Charleston's older housing stock, the humidity issues specific to the Kanawha Valley, and what each neighborhood's homes typically need.
We do not quote over the phone. A contractor comes to your home, looks at the actual space, and gives you a written estimate. There is no charge for this visit and no pressure to proceed afterward.
Before we leave, you receive written documentation of the type and amount of insulation installed. Keep it for your tax credit, your utility rebate, or if you sell the home. You will know exactly what you paid for.

They came out and actually looked at my crawl space before giving me a number. The quote was clear, they finished in one day, and my floors stopped feeling cold within the first week. Exactly what I needed.
I had a different company out before this one who gave me a number over the phone. These guys showed up, went up in the attic, and found moisture damage the other contractor never mentioned. They fixed it right.
Our heating bills had been climbing for three years and we could not figure out why. After the spray foam job in the crawl space and rim joists, the next bill was noticeably lower. The difference was real.
We respond to every inquiry within 1 business day. There is no obligation - you are just scheduling a free visit so we can see your home and give you an honest written estimate. After you submit, someone from our office will call to set up a convenient time for a free on-site assessment.

If your attic insulation is more than 20 years old or you can see the ceiling joists through it, it is time for an upgrade. Insulation compresses and loses R-value over time - especially in Charleston's humid climate where moisture accelerates deterioration.
Yes. Fiberglass batts lose 40 percent of their insulating value when wet, and cellulose can develop mold within 48 hours of getting damp. Charleston's 44 inches of annual rainfall and high humidity make moisture management a critical part of any insulation project.
If a room is cold, the problem is often air movement, not just insulation thickness. Air sealing gaps around pipes, wires, and framing has to happen first - otherwise warm air escapes no matter how much insulation is on top. Many older Charleston homes need both. wall insulation publishes homeowner resources that explain both types in plain language.
Closed-cell is the right choice anywhere moisture is a concern - crawl spaces, basements, and exterior walls. Open-cell works well in interior walls and attics for sound control and air sealing. A contractor who knows Charleston's climate conditions can guide you to the right type for each space. Spray Polyurethane Foam Alliance publishes homeowner resources that explain both types in plain language.
Ice dams form when heat escapes through an under-insulated attic, warms the roof deck, and melts snow that then refreezes at the cold eaves. They are almost always a symptom of poor attic insulation - and they can cause real water damage if left unaddressed through a West Virginia winter.
The U.S. Department of Energy estimates that properly air sealing and insulating a home can cut heating and cooling costs by 10 to 20 percent annually. In West Virginia, where energy costs are higher and housing stock is older, most homeowners see the investment pay for itself within 5 to 8 years.

Learn more about our companyBoth matter, but if your floors are cold in winter, the crawl space is usually the higher-priority fix. Heat rises, so attic improvements help more in summer. For an older home, a contractor can help you decide which delivers the better return first.
Wet or moldy insulation does not become inert just because new material covers it. It continues to off-gas and can affect the air quality in your living space. Removal costs more upfront but avoids a larger problem later.
Yes. The IRS offers an energy efficiency home improvement credit for qualifying insulation upgrades. The credit applies to materials, not labor. Ask your contractor to document the project correctly - you will need it when you file.
The U.S. Department of Energy insulation guide covers R-value recommendations for every climate zone. For your specific home in Charleston, give us a call and we will walk you through what applies.
Charleston is West Virginia's capital city and home to some of the state's most recognizable landmarks, including the gold-domed West Virginia State Capitol on the banks of the Kanawha River. The city's neighborhoods range from the longtime residential streets of Kanawha City to the larger homes climbing the ridgeline in South Hills. Many of these neighborhoods are full of homes built in the 1940s, 50s, and 60s - properties with real character and real insulation needs.
Charleston is built across a series of hills and ridges, with many streets winding up steep slopes above the river valley floor. That terrain means a lot of homes were built on sloped lots with uneven crawl spaces, tight attic configurations, and exposure to the cold air that settles into low-lying areas each winter. The city also receives about 44 inches of rain per year, and flooding is a genuine concern near the Kanawha and Elk rivers - which is why moisture management is such an important part of any insulation project here. The 2016 West Virginia floods brought that reality into sharp focus for residents across the region.
Charleston is also home to major employers like CAMC Health System and serves as the hub of state government - which means a stable community of long-term homeowners who invest in maintaining their properties. Whether your home is a few blocks from the Charleston Town Center or up in the hills on the south side of the city, Charleston Insulation Company knows what the local housing stock looks like and what it needs.
