Our crawl space had been a problem for years - cold floors all winter and a musty smell we could never get rid of. After the insulation and vapor barrier work, both issues were gone within a week. The crew was thorough and explained what they were doing at every step.
I had three contractors come out to look at my attic. Two gave me phone quotes without actually going up there. Blacksburg Insulation came out, measured what was there, and explained exactly what needed to happen and why. The job was done in a single day and my heating bill dropped noticeably that month.
We had spray foam done in the rim joists and crawl space. The estimator was upfront about the re-entry time and what we needed to do to prepare. No surprises on the invoice. The rooms above the crawl space are noticeably warmer this winter.
We respond within 1 business day - no automated systems, no waiting. There is no obligation to move forward after you hear our estimate. After you submit, someone from our office will call to schedule a free on-site visit so we can look at your space and give you an accurate quote.

At roughly 2,100 feet of elevation, Blacksburg sees colder winters and more snowfall than most of the state. The U.S. Department of Energy recommends significantly higher attic insulation levels for this climate zone - most older Blacksburg homes fall well short of that target.
Insulation slows heat transfer through materials. Air sealing closes the gaps where air moves freely - around pipes, wires, and light fixtures. Skipping air sealing is one of the most common reasons an insulation upgrade underperforms. Both steps work together.
Ice dams form when heat escapes through an under-insulated attic and melts snow on the upper roof. That water refreezes at the cold eaves and can back up under shingles. Proper attic insulation and air sealing stops the heat loss that causes them.
Closed-cell foam has a higher R-value per inch and acts as a moisture barrier - making it the standard choice for crawl spaces and basements. Open-cell foam is softer and less expensive, suitable for interior walls and attics where moisture control is less critical.
Old insulation that is wet, moldy, pest-contaminated, or severely compressed should come out before new material goes in. Adding new insulation on top of a damaged layer does not fix the underlying problem and may trap moisture or pests inside the assembly.
Yes. Blown-in insulation is added through a hose without opening walls. Spray foam can be applied to crawl spaces and rim joists through access hatches. Most retrofit insulation work causes minimal disruption and is completed in a single day. See{' '}the North American Insulation Manufacturers Association for technical standards that reputable contractors follow.

Add new insulation on top if the existing material is dry and undamaged. Replace it if it is wet, moldy, compressed significantly, or contaminated by pests.
Crawl spaces need insulation and moisture control. Left open to outside air, they drive up heating costs and create conditions for mold. Encapsulation addresses both problems.
Look from the attic hatch. If you can see the wooden framing members running across the floor, the insulation is too thin. They should be completely buried under the material.

Blacksburg sits at roughly 2,100 feet in the Ridge and Valley region of the Appalachian Mountains, which makes it one of the coldest towns in Virginia during winter months. The elevation brings real snowfall most years and freeze-thaw cycles that take a toll on homes. Homes here deal with weather conditions that most Virginia contractors do not regularly encounter, and the insulation requirements reflect that.
Blacksburg is best known as the home of Virginia Tech, which brings a stable base of faculty, staff, and long-term residents who own and invest in their homes. Many of the owner-occupied neighborhoods - including those near the Huckleberry Trail corridor and in the Hethwood neighborhood - were built in the 1960s through 1980s when Virginia Tech was growing rapidly. These homes are now 40 to 60 years old and many have never had their insulation upgraded.
We work across all of Blacksburg, from the older neighborhoods close to downtown on Draper Road and College Avenue to the newer subdivisions on the outskirts of town. Whether your home is on a wooded, sloped lot or a flat residential street, we handle the site conditions and give you an honest assessment of what your home needs to stay comfortable through a Blacksburg winter.
