What questions should I ask an insulation installer?

<div>When choosing a professional insulation installer, consider asking these questions to determine the best fit.<ul><li>Will you address air leaks in my house?</li><li>Can you provide an R-value (heat resistance) fact sheet?</li><li>What kind of insulation will work best for my home?</li><li>How do you handle signs of a water leak?</li><li>Are you licensed and insured?</li><li>Can you provide customer references?</li></ul></div>

What’s the best insulation for my house?

<div>The <a href="https://www.angi.com/articles/best-types-insulation.htm">best type of insulation</a> for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.</div>

Should I insulate my garage ceiling?

<div>If you plan to heat or cool your garage, you’ll need to <a href="https://www.angi.com/articles/how-save-money-garage-insulation.htm">insulate the garage ceiling</a>. 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.</div>

How do I know if I need more insulation in my house?

<div>In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few <a href="https://www.angi.com/articles/does-my-home-have-enough-insulation.htm">signs your home needs more insulation</a>, such as:<ul><li>High heating and cooling bills</li><li>Uncomfortable room temperatures </li><li>Ice dams on the edge of your roof </li><li>Roof leaks</li><li>Cold floors and walls</li><li>Freezing pipes</li><li>Temperature fluctuations</li><li>Visibly low insulation</li><li>Noise problems</li><li>Pest problems</li></ul></div>

How much does attic insulation cost?

<div>On average, <a href="https://www.angi.com/articles/how-much-does-attic-insulation-cost.htm">insulating an attic costs</a> about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:<ul><li>Blown-in: $1–$4 per square foot</li><li>Spray foam: $2–$5 per square foot</li><li>Batt: $2–$4 per square foot</li><li>Structural insulated panels: $4–$7 per square foot</li><li>Loose-fill: $2–$5 per square foot</li><li>Reflective: $0.50–$1.50 per square foot</li></ul></div>

Over 20 years of experience in the home comfort and efficiency field. We find solutions to the issues that your HVAC company can't. Dusty homes, hot and cold spots, high utility bills, drafty fireplaces, rooms above garages, cold floors, dirty carpet edges, and much more can be fixed by us. We provide "comfort and energy solutions".

"A total disaster. An inexperienced, untrained crew created more issues than I had before they began their work. My goal was to increase comfort levels in my senior-living, one-level home built on a slab that is super cold in the winter. I hate as a senior being taken advantage of. I was very naive. I have spent thousands and now am having to throw more good money after bad to try and make my home comfortable to live in. It is so bad; I am ready to sell! And I can’t afford to after all I have spent, without taking a loss on the sale. They dense packed my walls and now I am colder; in the process, they removed the flashing above my windows which now leak. I had to hire a window installer to replace the flashing that their incompetent crew removed. They failed to put back the siding properly, so it was hanging off my house. Once again, I had to hire a handy man to refasten the siding the crew removed while dense packing. And the dense packing was useless as it didn't enter the cavities that already had batt insulation. While spray foaming triangle boxes, boots, and plenum, they sealed off all my dampers resulting in zero air flow. They reluctantly came back and had to dig out the dampers that they had foamed over. In fact, they over-foamed at junction boxes, boots, and plenum so that HVAC techs couldn't even tune my system. There is 2 feet of foam, yet hot air is rushing out of the flexible ducts that weren’t sealed properly. Yet there remain gaps on my boxes, boots, and plenum. Just today, a HVAC tech walked me around the attic, and I could feel the hot air rushing into my attic at the junctions, boxes, boots, and plenums that are all wide open; that I paid to have sealed. I almost threw up; I am heating my attic! And the tech said it looks like a dog was in my attic as the Comfenergy crews failed to put back my blown-in fiberglass insulation they removed when trying to foam, so there is no insulation at the boxes and boots. They were simply careless and failed to rake it back and even out my insulation resulting in further cold spots I didn't have. In short, I now will have to hire another company to blow in more insulation and make sure it is even, so I don't have cold/hot spots. Additionally, they left the lights on in the attic, didn't replace the attic access foam barrier, and failed to seal the major penetrations including light cans/recessed lights and supply vents I paid for. Next came the bathroom exhaust fans; they were installed improperly and didn't vent because the outside flaps remained closed, while inside a cold draft came in my bathroom because the foam sealing, I paid for wasn't done properly. So now both my bathrooms are drafty. They were cold; now they are cold AND drafty. The HVAC tech today remarked he felt badly that I have two or more space heaters in every room, including the bathrooms! I strongly recommend carefully watching the crew if you ever choose to allow them to do any work for you. I trusted them. And I regret that. I was naive. I was cold. Rather I am still cold! I trusted their salesperson. The crew that did mine were either let go or quit. In fact, one of them still calls seeking to do side work. I politely declined. I suggest you do the same and seek a competent company that you can trust, does the work you paid for properly, and doesn't damage your home."
