"Shane and his crew were awesome - removed a ton of old, nasty insulation from the attic of our investment property. Left everything spotless. Extremely competitive pricing. We will definitely use their services again."

"The process went very smoothly.  There were several teams that worked on my project.  The initial workers removed all of the old insulation and trash left under the house during construction, and cleaned the joists.  Later a perimeter drain system was installed, and the final job was to insulate the foundation perimeter and install the vapor barrier.  

All the work was done in a professional manner and the workers were all very courteous.  They were on time and on budget."
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.

"Matt Epperly was very professional and new about insulation for our crawl space. He came and went under our house and took pictures. We did not know about the mold which he showed us. He made the suggestion of the spray foam and the Friction-fit rigid foam board door panel to be installed behind our existing crawl space access door. Spray Foam in crawl space rim and band joist for air-sealing and insulation. He also mentioned before the foam insulation spraying anti-microbial solution on all crawl space wood substructure. We were also told we would get free a Wireless Hygrometer. It displays the temperature and humidity both inside your crawl space. It was all accomplished in a few hours. They informed us for our protection to leave the home and come back. Everything was done neatly and no mess left."

"Expect for them to be on time, that they will cover the floors, that a window may be opened for an extended period if adding
insulation.  There will be loud noise if adding insulation so be prepared.  Find a comfortable place to be while the
work is being performed if you are waiting at the house.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

"Barry and his assistant showed up and started working on the otuside inspection while we were waiting for the realtor to arrive. They did a thourough visual inspection of the house and made sure that outlets, plumbing, gas and light fixtures were working properly and had the necessary covers on them. After the visual inspection with photos being taken they performed a thermal scan of the walls in the house to look for moisture and possible infestations.

Insulation questions, answered by experts

A vapor barrier can last over 20 years, but they are vulnerable to pests, flooding, and other natural disasters. If your home weathers a storm or is treated for any pest infestation, make sure to have a drywall pro come check the integrity of your vapor barrier. It’s also important to have a pro install a vapor barrier since improper installation can lead to tears or leaks in the barrier that shorten its lifespan.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

Yes, spray foam insulation can be applied to your ductwork and effectively insulate your ducts. Blanket insulation is the easiest insulation product to DIY since it is easy to wrap around ducts. However, spray foam insulation can also benefit your HVAC system if applied to air ducts.

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.
