"Fantastic and professional. We have a small house and lost some of our gutters to a snow storm, so we decided to renovate the rest of our gutter system while repairing the damaged sections. Working with HGE was a refreshingly positive experience. All of their team members were courteous, straightforward, and responsive. The work took two days with a weather interruption in between, but communication was prompt which let us accommodate the weather. All in all, great company. I just wish they did fencing so I could hire them 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."

"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 questions, answered by experts

Insulating your ducts offers several benefits, including:

  • Improved energy efficiency: Duct insulation prevents energy losses, reducing heating and cooling costs.

  • Cost savings: Lower energy bills make insulation a cost-effective investment.

  • Environmental benefits: Enhanced efficiency reduces your carbon footprint.

  • Consistent comfort: Insulated ducts help maintain a stable indoor temperature.

  • Better indoor air quality: Reduced allergens and pollutants improve air quality.

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.
