Old, wet, or pest-damaged insulation makes your home worse, not better. We remove it safely before putting in a clean, effective replacement.

Insulation alone can't stop air leaks. Professional air sealing closes the gaps around pipes, wires, and fixtures that let conditioned air escape.

An uninsulated basement pulls heat from your floors and drives up your heating bill. We insulate rim joists and walls to stop the loss.

Moisture rising from the ground under your home causes rot, mold, and poor air quality. A vapor barrier stops it at the source.

A properly installed vapor barrier protects your crawl space, basement, and the floors above from long-term moisture damage.

Heat escapes through every gap in your attic floor. Air sealing those gaps before adding insulation is what makes the real difference in efficiency.

Older Danville homes weren't built for today's energy costs. Retrofit insulation adds coverage to existing walls and spaces without major renovation.
Learn MoreYou reach out by phone or through our contact form. We ask a few quick questions - your home's age, the space you're concerned about, and what you've been noticing. No long forms, no hold music. We respond within 1 business day and can usually get on your calendar the same week.
A technician visits your home and walks the attic, crawl space, or walls in question. We measure what's already there, check for moisture or damage, and identify where the energy is actually leaving. You get a clear written estimate that explains the work in plain language - not trade jargon.
Our crew completes the installation, cleans up, and walks you through the finished job before leaving. Most attic and crawl space jobs are done in a single day. You can see what was installed, ask questions, and leave with documentation you can keep for your home records or tax filing.
We carry full liability insurance and are licensed to perform insulation work in Virginia. Every job is covered, so if anything goes wrong during the work, you are not the one responsible. We will provide proof of insurance before work starts if you ask.
We never quote over the phone for jobs we haven't seen. An estimator comes to your home, looks at the actual space, and gives you a written number. You owe us nothing if you decide not to move forward - and we won't pressure you either way.
We are a locally owned company, not a franchise or a regional chain. We know Danville's housing stock - the older brick homes in Schoolfield, the crawl space foundations common in this part of Virginia, and the humidity conditions that make moisture management such an important part of every job here.
Every job comes with a written record of what was installed, the materials used, and the coverage achieved. If your project requires a permit, we pull it and coordinate the inspection. You get paperwork you can keep with your home records - useful at tax time and when you sell the house.

They came out the same week I called, found that my attic had only about 3 inches of old insulation, and had it fully blown in by the end of the next day. My upstairs bedroom has been noticeably cooler ever since, and my July electric bill was the lowest it has been in years.
James T., Danville, VA - Attic insulation
I had spray foam done in the crawl space under my house. The crew was upfront about what they found - some moisture damage I didn't know about - and they explained everything before starting. The musty smell that used to come through the floors is completely gone.
Patricia M., Martinsville, VA - Crawl space insulation
My 1960s home had almost no wall insulation. They did a retrofit job that required drilling into the exterior, and the crew patched everything cleanly when they finished. The drafts I used to feel near the outlets are gone, and the house holds temperature much better now.

R-value measures how well insulation resists heat flow - the higher the number, the better. For attics in Virginia's climate zone, the U.S. Department of Energy recommends R-38 to R-60. Many older Danville homes have far less than that.
Insulation slows heat, but air leaks let it bypass that barrier entirely. Gaps around pipes, wires, and light fixtures can make even thick insulation underperform. Sealing those gaps first is what actually delivers the energy savings you're expecting.
If your crawl space is conditioned (heated or cooled), you need insulation on the walls, not the floor. If it is unconditioned, insulation goes between the floor joists. Either way, a vapor barrier on the ground is almost always the right first step given Danville's humid climate.
If you can see the wooden joists in your attic floor, your insulation is too thin. Other signs include rooms that are impossible to heat or cool evenly, drafts near outlets on exterior walls, and energy bills that spike sharply every summer and winter.
Blown-in insulation is faster and more cost-effective for open attic floors where you just need more coverage. Spray foam is the right call when you want to air-seal at the same time or when the space has moisture challenges - like an encapsulated crawl space.
Yes. As of 2025, the federal government offers a tax credit covering up to 30% of qualifying insulation materials, capped at $1,200 per year through 2032. The ENERGY STAR federal tax credits page has the most current details. Ask your contractor for the documentation you need to claim it.

Always insulate first. A new HVAC system in a poorly insulated home will be undersized for the actual load, run constantly, and wear out faster. Fixing the envelope first makes your existing system perform better and helps you right-size any future replacement.
Moisture needs to be addressed before new insulation goes in. Installing over a wet crawl space traps moisture against the structure and creates ideal conditions for mold and wood rot. A good contractor will identify the source and recommend a fix before scheduling the insulation work.
The materials installed must meet specific thermal performance thresholds. Your contractor should be able to confirm eligibility when they give you a quote and provide the manufacturer certification document you need at tax time. The North American Insulation Manufacturers Association maintains a resource guide for homeowners on this topic.

Danville Insulation operates out of Danville, Virginia, a city of about 40,000 people in the southern Virginia Piedmont, just a few miles north of the North Carolina border. Danville sits roughly 45 miles north of Greensboro and about 60 miles south of Roanoke, and its location means we routinely serve homeowners across both states. The city is home to a mix of older neighborhoods - including the historic Schoolfield mill village, where row after row of century-old wood-frame homes still stand - and newer subdivisions out toward Ringgold and Blairs.
A significant portion of Danville's housing stock was built before 1960, which means many homes in the area were constructed long before modern insulation standards existed. These older homes - many featuring brick exteriors, crawl space foundations, and original wood framing - are exactly the type we work on most. They often have insulation that has settled, compressed, or was never adequate to begin with. The Dan River corridor and surrounding neighborhoods like Holbrook and Green Street are dense with homes that benefit most from insulation upgrades.
Danville's hot, humid summers and cold winters create real pressure on homes that aren't properly insulated. The region's clay-heavy soils also hold moisture near the surface, which makes crawl space conditions a consistent issue for homeowners here. Whether your home is near the Danville Science Center or out in one of the surrounding communities, Danville Insulation knows what the housing stock here looks like and what it needs.
