"My wife and I were so pleased with Chris and his team from the work on our crawl space that we hired them to remove and install new insulation in our entire house. Due to a previous leak in the roof the insulation wasn't effective. All About Energy Solutions came in and removed all of the old insulation and put new insulation in. They also added a radiant barrier. Chris is extremely knowledgable and passionate about what he does and wants to teach you about the benefits of the solutions they provide. This has been the second job we have hired Chris for and wouldn't hesitate to hire him or recommend him. Chris continues to go above and beyond for us."

"Did not do work, but pricing was competitive with everyone else.  Invoice got lost in junk e-mail, so did not think I ever received invoice, but I found it a month or so after job was completed again.  If\when I have another job will call All Foam and make sure Invoice doesn't get lost in junk e-mail!

"An employee came out with the subcontractor to do the energy audit. They did a thorough job with the audit. The Fresh Air employee went into my attic and said we needed more insulation. He said he could cure the cold air issues and came back with a quote of $1,200. I escaladed the service through Angie’s List. A few months later they fired the gentleman who I had been working with. After talking with the manager I found out that the representative had grossly increased my price which I thought he had. He tried to double charging me. The owner had someone come out to blow the 500 square feet of insulation. They did the work as it should have been done. They did everything they could to make it right by a bad employee."

Insulation questions, answered by experts

Prioritize insulation service if you notice crawl space moisture or post-storm damage. Lancaster experiences hot summers and freezing winter nights, making inadequate insulation a year-round issue that strains your HVAC system. Address older homes with no existing coverage immediately to prevent mold and structural damage. Schedule supplemental upgrades for already code-compliant homes or garages during the late winter or early spring off-peak season to avoid high demand.

Helpful?

High summer energy bills and an HVAC system that runs continuously are clear signs you need insulation service. Look for physical indicators like visible condensation on interior walls, musty odors from crawl spaces, or frost on attic sheathing during winter cold snaps. Homes built in Lancaster before 1977 lack adequate thermal protection. Schedule a formal South Carolina residential energy audit to pinpoint exact failures and plan your upgrades.

Helpful?

A major mistake during insulation service is prioritizing attics while ignoring wet, unencapsulated crawl spaces, which accelerates rot. Homeowners also err by skipping crucial air sealing steps or settling for minimum code requirements instead of optimal thermal values for the local climate. Finally, avoid scheduling your project during peak summer humidity in Lancaster. Trapping summer moisture inside building cavities causes severe damage, so schedule work from late fall through early spring.

Helpful?

When planning insulation service, consider local climate factors like termite risks and the benefits of crawl space encapsulation over traditional venting. Since the city features a historic district, exterior envelope changes require approval before work begins. Contractor availability tightens significantly from April through September. Schedule your project in late fall for the best availability. Finally, check for regional utility rebate programs in SC to maximize the value of your upgrades.

Helpful?

During insulation service, local professionals uncover existing moisture damage or mold in crawl spaces and attics due to high humidity. Remediation must happen before adding new materials. You incur added expenses if contractors find active knob-and-tube wiring or inadequate ventilation. Additionally, South Carolina energy codes require specific vapor barriers and thermal envelope upgrades, and your HVAC system requires resizing if the new insulation makes it oversized.
