"Eric responded immediately and set up a consultation. He was prompt, very polite, thorough and knowledgeable. He explained everything in detail and was very professional throughout the entire process. His pricing was also quite fair. The only reason I did not go with him was that I needed other work done outside of his area of expertise. I was able to bundle that work with another insulation contractor which better suited my budget at this time. I would absolutely recommend Eric and will definitely contact him, should I need any additional work in the future."

"Best experience I’ve had with home improvement. Professional from start to finish. They came in priced a bit higher than others but the professionalism, quality and ability to work with my schedule more than made up for the slightly higher cost."

"They came right out to give the estimate and advised there was an opening in about two weeks. They actually called 2 days later and got me in the next day. They finished quickly. Unfortunately I had previous loose blow in insulation that got everywhere. This was not their fault it was not able to be avoided. Would recommend them again."

"The salesperson who came out was very nice and professional - however, he did not tell me that I needed to have everything in the basement 3 feet from the walls.  This caused us to scramble on the day of installation and i'm certain that this made it more difficult for the installers as well.  Additionally, no one had warned me of how strong the smell would be initially and I had to scramble a bit to get my very young family out of the house to avoid it and/or off-gassing.  The installers arrived on time and were ready to roll.  They did an excellent job insulating the rim joists and did a pretty good job of cleaning up.  There were some spots where I had to scrape the insulation off of the floor and wall.  Overall, I would recommend them for small jobs such as this.

Insulation FAQs, answered by experts

Yes, you can install insulation over ductwork, and doing so can save you money. Without insulation, the HVAC unit must work harder to force warm or cool air around the home, and once the air reaches the vent, it may not be the correct temperature. Insulating HVAC ducts makes your system work more efficiently, saving you money on heating and cooling bills.

Insulating ducts prevent or significantly reduce condensation by reducing temperature differences between the duct surface and surrounding air. Proper insulation also minimizes sweating, improves energy efficiency, and prevents moisture damage. However, if humidity levels are unusually high or there are air leaks, additional measures like sealing ducts and using a dehumidifier may be needed.

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 always need to remove old insulation before adding new. If the existing insulation is in good condition—not wet, physically damaged, moldy, or infested with pests—you can add new insulation directly on top of it for a compounding effect. You can also mix different types, such as adding blown-in insulation around existing fiberglass batts.

However, removal is recommended if the old insulation is compromised by water damage or pests. You should also remove it if you plan to install a different type of insulation, like switching from roll or batt insulation to spray foam. If the existing insulation is very old or damaged, you will likely get more benefit from removing it and starting fresh.

You won’t find anything inside a cupola on a house because it’s hollow (think of an upside-down cup), allowing air to ventilate out of a roof via vents and light to come in via windows. They also usually have a base, vents around the middle (usually louvers), and a pointed cap at the top.
