"I asked for an estimate on foam insulation. The amount of insulation in my attic was good. I actually needed a reflective barrier to deal with the heat build up on one end of my home. Since the reflective barrier was installed my home has been comfortable. My HVAC has not had to work as hard to keep the house cool. They also installed an Insulation barrier over the attic door which prevents heat from entering the house from the attic. We are very happy with the end results and the work."

"Since 7/2025 I knew we needed insulation blown into our less than 1300 SF 1973 built home. Got a quote for over $5000, left messages at many more and some didn’t even show up or return my call. On 12/16/2025 I called Angi list and was told someone would be calling me back soon(bet they want!) Well they did and I spoke Nick Martin of Martin Home Solutions and gave me a quote that I was able to pay (We are old!) and he and Jason Farmer came to our home last evening 12/17/2025!!! (Ready To Work!) We were so impressed by Nick’s honesty, open communication and work ethic. We were so very happy to know that we can survive this winter financially with adequate insulation in our attic. Call Angi List today if you are searching for someone for your attic needs, Martins Home Solutions will not disappoint."

"When I had originally contacted Bia Insulation I was pleasantly surprised at how quick and easy the process was to set up my appointment with them. Once everything logistically was taken care of, insulation install process came and went in a swift manner. I was highly impressed with not only how professional but personable Jeremy was. He was my go to guy from start to finish and that meant a lot to me. Having the one point of contact throughout the whole process was breathe of fresh air. As far as savings go, my wallet and my wife are VERY happy. We noticed savings on our bill within the first couple of months."

"We had a pest problem (mice) in our attic and crawlspace. As a result, we needed to not only remove the pests and close up entry / access points but also to remove and replace the 30+ year old insulation in our attic. We had read many positive reviews as well as received personal referrals from friends for the team at Complete Animal Removal / Complete Insulation and we were not disappointed. Many thanks to Michael for meeting with us for the initial inspection, answering questions, and guiding us through the process. The Teams from Complete Animal Removal / Complete Insulation Inc. did a fantastic job. They were very thorough and professional. The team at Complete Animal Removal worked through the pest removal process and closed up all entry and access points to prevent future issues. This process took several weeks and included sealing up all access points in our attic, crawlspace, etc. Once we had the pest issue under control, the team at Complete Insulation removed all of our fiberglass insulation in our attic and installed new closed-cell spray foam insulation. The spray-foam insulation install process went very smoothly. We had one minor electrical item that needed to be addressed in the attic while the team was prepping for the install and the team had an electrician onsite same day. We really appreciated the guys knocking out the install in a single day. Many thanks to Josh Gilbert, Josh Francis, Colton Brake, Alex Moulton, and Dylan King. They laid down heavy plastic to protect all of our hardwood floors and cleaned up when they finished. I've posted several pics to show before and after. We are very pleased with the outcome and would recommend to family and friends."

"Ethan explained (in detail) how they would not only set up the panels on top of my home, but that they will also "pressurize" my home, including my air conditioning unit, to ensure that I get the best service possible from my panels!  He explained every detail of cost, taxes, and best of all REBATES!  He explained several methods of purchase, as well.  I have his personal cell phone number in case I have questions, and I can call their office at ANY TIME if I need anything.  So far, my experience with Sunpro Solar (Mandeville, LA) has been nothing short of great!  In a few weeks, I'll have my solar panels installed.  The time it has taken to get to this process has been minimal.  Everyone I've spoken with at Sunpro Solar has been friendly, helpful, knowledgeable, respectful, and accommodating.

Insulation questions, answered by experts

Although spray foam insulation typically has a higher price point than traditional insulation, the benefits often justify the investment. It offers superior sealing properties, which can lead to significant energy bill savings. Spray foam also provides excellent moisture resistance and soundproofing. Other advantages include improved indoor air quality by minimizing allergens, a long lifespan of 80 to 100 years, added structural strength to the home, and a straightforward installation process.

If you’re moving wires, installing new wires, or installing new fixtures in the space you’re insulating, then you will need to hire a licensed electrician to do that portion of the job for you. However, if you just intend on replacing old insulation or adding new insulation over existing insulation, then you don’t need to hire one. Your insulation installer will work around wiring, fixtures, outlets, and switches, even if they’re installing fiberglass batts in the voids where wires run. However, you will need an electrician if you suspect a problem with your wiring during the insulation work.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.
