"Some initial prep information was a bit lacking in detail, which caused rescheduling of work, but went well after that. Insulated crawlspace that was severely lacking insulation from cheap & crappy house builder (HH Hunt). Foam insulation on sides/walls & certain posts/beams, 10 mil drymat on ground, sealed off vents. Workers friendly & professional. Bit pricey but noticeable improvement soon after finish...floors were not cold in certain areas as before."
Unsealed porous foundation walls. Efflorescence has grown along the outside walls.
Plastic is laid out to protect the freshly pained walls and floor.
Open vents in the foundation walls allow outside air and moisture to infiltrate the crawl space, increasing the relative humidity and allowing mold spores to thrive inside.
Spray foam application in progress on warehouse walls.
The dirt floor is exposed, which will allow the moisture from the earth to rise uncontested into the crawl space, adding to the increase in relative humidity.

"Insulating a crawl space is incredibly expensive (especially for a space that hardly anybody ever sees or goes into), but they did a good job and it has helped in keeping the pipes warmer in winter and reducing damp feeling inside the house."

"The decision on who to choose and what to install was a very difficult one for us. It’s not everyday that you are faced with such an expensive decision. Every HVAC dealer out there has a different opinion on the type of equipment (size, brand, efficiency, etc.), and every homeowner seems to have a different experience with the equipment regardless of the brand. Ultimately it was the 10 year LABOR warranty that made us choose York. No other manufacturer offers a direct labor warranty (I called all the major brands), and based on our past experience the labor warranty was a no brainer. We chose Automatic Climate based on the competitive price, the existing relationship, Angies List reviews, and their initial visit with us. The install and system startup went very smooth. The lead technician stayed, directed, and helped until he knew the guys had everything they needed, including using his leaf blower to ensure they knew exactly what lines to move to the new trunk. He also remembered the little things like insulating the new drain line. The other guys were great as well. They were happy to answer questions that I had on the new system, and they were just personable overall. They were careful not to bang up any walls and really did a nice job cleaning up. I plan to use Automatic Climate again when my 10 year old downstairs unit dies. Nice job, guys!"

"The installers were professional and courteous, they cleaned up after themselves and left my home in the same condition as when they arrived. The blown-in insulation has made a noticeable improvement over the temperature on our 2nd floor."

Insulation FAQs, answered by experts

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Yes, there are government incentives available in some regions for insulating air ducts as part of energy-efficient upgrades. These incentives aim to encourage homeowners and businesses to improve energy efficiency and reduce their carbon footprint. To determine whether you qualify for such incentives, check with your local utility company or government agencies. They often offer rebates, tax credits, or other financial incentives that can help offset the cost of duct insulation projects.
