"I’m a land lord of 72 residential properties and the biggest head ache other than common upkeep was the constant battle with roaches and insects inside the units, I had Triple B come out and put their pest control infused insulation at 10 of my properties and within 3 weeks the tenants were in shock at how affective it was, they went from seeing them everyday to hardly ever, I ended up getting them to do all my units and also my own house, this will be a must at any property I ever purchase, highly suggested for new home owners/buyers"

"Contacted a few different companies and had two come out to inspect a large crack in the foundation. First company came out and indicated that the foundation had failed and needed piers put in to stablize the foundation. Crawlspace Solutions came in and indicated that they felt there was nothing failing with the foundation and that they could inject the cracks and warranty the work regardless of if there was a larger issue that required piers. Scott was the person that estimated and completed the work. He was extremely responsive and did a very good job of injecting the cracks. When Scott came to quote the work he also offered a price to apply spray foam to the walls and the sill to replace the fiberglass insulation that the previous owner of the house had on the crawlspace walls. Price included in review was to inject 2 cracks and apply the spray foam. Really glad we had the foam insulation put in. Way cleaner, durable and sealed up some areas that the other insulation could not take care of. Scott also spent extra time explaining some other areas to keep an eye out on to help ensure the foundation area is well managed from any further potential issues like down spout discharge locations, hose connections and just general drainage of the property. One of the concerns we had was if we spend all this money on the injection and the foundation ends up needing to have piers put in, how would that impact the warranty. Scott assured us that if any additional settling occurs and the repair fails, they would come back and repair the injected cracks after the foundation was stable."

"Elijah and Nico came to provide us with an estimate for the insulation job we needed. They really took their time to explain the issue, showed us images on their nifty camera, and offered us a few options for the fix with a few DIY fixes for the smaller issues. They were both very easy to talk to. The day of the job Elijah and another team member were punctual and respectful of our time and property. In todayâ s economy it is easy to get ripped off by contractors, but you donâ t have to worry about that with ENE. Their prices are fair and the quality is great. A few days after the job was done we had below freezing temps and we could notice the improvement. I will definitely be reaching out to ENE for another project, and highly recommend them!"

"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."

Insulation questions, answered by experts

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.

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.

How to dispose of insulation depends on a few factors, including the condition of the material. While you can simply bag up and throw away many kinds of insulation, some municipalities offer recycling, so it's worth checking with yours. If there are contaminants such as asbestos in your insulation, abatement and specialized disposal are often necessary.

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.

To cover your HVAC ducts and air vents during construction, use plastic sheets or drop cloths secured with painter's tape. Be sure to cover all supply vents on your floors and walls, as well as the larger HVAC return vent, which is typically on the ceiling. While canvas drop cloths can also be used, they may not catch all the fine dust. It is crucial to shut off your HVAC system or at least the zone where construction is happening. Running the system with vents sealed can put significant strain on the blower motor and air handler. For additional dust containment, you can also hang plastic sheets over doorways to separate the construction area from the rest of your home.
