"What an absolute DREAM! Correct Energy is an incredible company. Knowledge, professional and efficient! I contacted a few insulation companies but the proposed methods were not through. Correct Energy and especially Ray’s knowledge and experience were above and beyond. CE came out to assess and spent a generous amt of time explaining EVERYTHING. CE came when they said they would. The crew was professional and spent a few days here. They left everything immaculate. My place is old, built in the 1940’s so many challenges came up that they handled like absolute pro’s. Their work has and will continue to save so much on energy, the difference of before and after is immediate and drastic. I can’t wait for them to come back and do my basement next! I can't say enough about this company. Pros work here!!! Hire them!!! You will not be disappointed.."

"Overall, excellent. We did encounter a few problems with the spray in wall insulation since the original sheet rock was just nailed in. A few sections bowed into the room. This is actually pretty common with old houses. The problem was quickly corrected, the walls properly secured, the insulation reinstalled (blown in) and the job completed. In modifications to a home, it is not always the problems you encounter, it is how you deal with them. Advance had the problem identified with a resolution that was completed within a day. Very pro-active!"

"I hired them to remove old fiber glass insulation in attic and replace with blown in cellulose insulation along with sealing airflow from the 1st floor. The job was quoted as taking 3 days, it took 5 days and then we had them come back for items that were not up to par. No doubt this is dirty, hot, nasty work and for that I appreciated their efforts. But to honest I felt we had to squeeze them to get the best possible service possible. The workers arrived at 10am earliest and did about 4-5 hrs of work each day. We had lower quotes but went with the because of the 0% loan 6 mos loan and their paperwork showed their insurance. On paper they look professional, but I think their follow through is somewhat lacking."

"Paul Willing arrived promptly and spent several hours inspecting a recently constructed home. The inspection discovered 15 areas which were defective/marginal, one of the most serious being an incomplete and potentially hazardous HVAC installation. The inspection report was sufficient to compel the contractor to complete the work. Paul also made numerous suggestions to improve various features of the house. The report was detailed and supported by photos and I am sure it prevented many future issues associated with new construction. Money and time well spent."

"They did a great job with adding cellulose insulation to by exterior walls. We had some problems getting a hold of the salesman but nothing to complain about or stop us from recommending this company. Great value for the money."

"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 FAQs, answered by experts

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.

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

These two types of foams are similar chemically, but they are applied in a much different way and each has its own pros and cons. Spray foam can only be used if the area where you will be installing the installation is wide open and easy to access. Injection foam should be used where it's cost-prohibitive to remove the walls that are placed over the insulation. Spray foam is a much less expensive process and requires less expertise. 

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.
