"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.

"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

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

Although it’s not required, air ventilation in a finished basement can help improve the air quality, prevent moisture and mold issues, keep musty odors away, and also maintain the air quality throughout the rest of your home. Proper ventilation will help maintain the value of your investment in finishing your basement. Try basement ventilation methods like installing vents or a dehumidifier for best results.

You do not need to drywall over most types of garage insulation. However, doing so can increase noise reduction, make the space more attractive, and keep children and pets from touching harmful fiberglass insulation. If you’re using cellulose or some other type of blown-in insulation (fiberglass and mineral wool are common), you will need drywall to contain the insulation material.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

Yes, usually you will need some kind of vapor barrier on the exterior walls when the framing is attached to concrete and masonry surfaces.
