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>

"ROOFTOP DESIGN IS A HORRIBLE SCAM I would be remiss not to take the time to warn others. ROOFTOP DESIGN came as a third option for roofing. However, the initial representative ED form ROOFTOP DESIGN was very professional and thorough. The problem is, he represented a bunch of shysters. Ed’s first quote to was $35,000. After approximately three days of conversation and negotiations we were at $17,000.00 for the exact same product that they tried to sale for $35,000. Salesmen Ed was no-longer reaching out to me. Someone by the name of John called me and asked, what is it that they can do to make this deal happen. We settled at $16,500.00. Once again, $16,500 for everything discussed for the original $35,000 including a 50-year warranty that is transferable to a buyer as a good selling point. I learned through John that they fired Ed for giving customers too good of deals. I also learned through John that this company has a starting bidding price and a bottom bidding price. Ed would give the bottom price too quickly. So, they fired him. (Although John’s price was better than Ed’s). Once the job started, I received a text from the owner Yanni Avramidis. He stated that there was a third layer of roofing. He also stated that it would not be a problem and that it would take a little longer. IF THERE WAS GOING TO BE ANY ADDITIONAL CHARGES, NOW WOULD BE THE TIME TO MENTION IT. Approximately two days after the completion of the job. I had a contractor over named B. B. was there to replace the soffit beneath the location where the new roof was installed. This is when I learned and saw with my own two eyes that there was rotted or no plywood at all supporting my brand-new shingles. Mind you: per our contract, there will be an extra charge for plywood beyond the first ten free sheets. This company put my expensive shingles on top of rotted wood or no wood at all. I must admit, I was upset. However, I was cool calm and collected when I reached out to the owner Yanni Avramidis. I sent him the pictures of my findings. His explanation was that I had a 50-year warranty. My point to the owner was, if I wasn’t trying to replace my soffit it might have been months or years before this was discovered. I also said, what about the elderly man or woman that doesn’t have the ambition to check your work??? The owner of ROOFTOP DESIGN became very irate. He said, “I am from Baltimore, haven’t you heard about people from Baltimore. I will beat your a**. You are going to pay me an additional $2,800.00 for the third layer of roofing and planks/ plywood.” Since I have yet to see any new plywood, I am being charged $3,000.00 per layer of roofing to be removed. I received paperwork from ROOFTOP DESIGN, the paperwork stated that my warranty was only good for as long as I owned the property. Non-transferable: Of course, I didn’t sign it. My point is, there are people being taken advantage of everyday by bullies like ROOFTOP DESIGN."

"American Home Contractors and Hugo in particular were great to work with. We had multiple jobs done which required several trips and Hugo kept us informed and worked around several weather delays. He relocated and installed a new attic fan, hooked up the bathroom fan to a new roof vent, insulated a pipe in the attic, installed apron flashing on four windows, painted the flue vent, reconnected some lose siding and replaced three pieces of rotted trim and painted it. The work appears to be top notch and we appreciate the hard work and long hours Hugo put in! I would definitely recommend this company and most certainly Hugo to everyone. We also had American Home Contractors replace our gutters and install gutter guards. They did an excellent job with that as well."
