"Ralph Bertrand from Home Genius Exteriors came out to thoroughly examine our roof. Ralph showed us many photos & a video of our roof, outside & inside. Ralph took the time to answer any questions we had. He explained the various products used & levels of warranty available. We really appreciated the time Ralph spent explaining everything to us, all without pressure to buy. The day of install arrived & the team was on time & ready to work! One thing we liked was that there was someone there from Home Genius Exteriors during the whole time of install. Richard Bowan, the Install Manager, was there to oversee everything & he did an amazing job. They placed large tarps over all our landscaping & got right to work. Rich kept us updated on progress throughout the day & answered any questions we had. In addition to the new roof, we also had new gutters with leaf guards & downspouts installed. When the work was completed, we walked around the house with Rich. Everything was completely cleaned up; there was nothing left behind or out of place. Our home looks amazing. The new roof, gutters & downspouts really look beautiful. We loved our experience with Home Genius Exteriors, especially working with both Ralph & Rich. They were so professional & knowledgeable. We would recommend them to others & if we needed additional work, we would definitely call Home Genius Exteriors."

"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 ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Once installed, injection insulation requires little maintenance, but periodic inspections for air leaks or moisture buildup are recommended.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.
