"The crew that originally came out were very efficient and friendly. They finished almost everything in the time that was stated. The only thing with them that I was concerned with was that they keep asking me what they were supposed to be doing. They knew that they were supposed to doing insulation but didn't have the details. And when i told them that I would have to go back to my paperwork they said that they would call the project manager. On the 3rd day they needed to do one last thing to an outer wall but couldn't do it because it was too cold and they were concerned that if they tried to remove the siding it would crack. They left on a Wednesday telling me that someone would contact me to come back on Saturday to finish the job. Fast forward to Friday, I get a few missed calls and then text messages saying that they had a crew in the area that wanted to come by in 30 mins. I wasn't home but finished up what I was doing to meet them at my house. When they get there they don't even know what the job is that they are supposed to be doing and don't have a ladder tall enough to reach the area. So they decided that they could do the job from the inside and said that they would need to drill a couple holes in my closets to fill the wall with insulation. They were very admit that that the holes would be repaired and the drywall fixed and painted and that someone in the company would call me and a crew would come out to do the drywall repair. So they do their part and leave. After they leave I realize that they put 6 holes in my wall. Not what i was expected but they did a decent job on plugging the hole back up with the piece of drywall that they removed. I waited for someone to call me about fixing the drywall but they didn't call. So after a week of waiting I called the company to ask about it and the mold remediation issue I was having (more on that in a sec). They seemed unaware on the drywall needing to be fixed and said they would send someone out to look at both things. A few days later someone comes out. They were unaware of the drywall repair but were there to look at the mold issue. Now about the mold issue. I will get back to the drywall in a min. So I paid for them to spray something on a strip of mold that we had in our basement and was told that after it has been sprayed that it would like nothing was ever there. Well after them spraying it twice it still looked awful. The wood looked but as black as before they came. So when these guys came to look at it they said that there was definitely no mold there. the problem was with my wood. So much for it looking like nothing was there. Now i have to hire someone else to sandblast it or something. So after these guys looked at the basement they said that they would look at the drywall. They look at it and are like "oh, i don't think we have the materials on our truck to fix this but I will take a look". They did have the materials and would tape it and mud it but weren't really experienced in drywall repairs but they knew enough to do the job. I should have stopped them right there but I thought it would be okay. Well once the mud dried I could tell what an awful job they had done. I will have to either try to fix it myself or hire someone to do it. And I probably should have called them back again but I am really tired of them sending me people that don't know what the job is before they get to my house and are not prepared. Only getting a C because the first crew was decent."

"After my call to Discount Energy Services, I knew who was coming and when to evaluate my attic insulation. The estimate was prepared on-site with pricing. The workers arrived and knew exactly what they were to accomplish, which they confirmed with me. They prepared the entire path with clean drop cloths and created a plastic drape around my attic stairs. The foreman was glad to explain any aspect of the procedure. My attic was upgraded to R-49 and the difference is notable."

"I had several options to pursue in finding a remedy for my hot attic. After meeting with the insulation consultant who was extremely knowledgeable, patient, and provided detailed explanations of how to insulate I knew proceeding with the job was the right decision. My attic is noticeably cooler and I highly recommend"

"I had multiple estimates and Fifth Fuel was the most professional and reasonable. Josh came to my house, took pictures of my attic and explained the different choices of insulating the attic. He provided an estimate in writing the same evening. The installers arrived on time, sent me photos of the before and after. They left the house clean with no debris. The result is a huge improvement in the temperature between the upstairs and down. I couldn’t be happier with them! Outstanding!! Thank you!"

"They wanted to inject very expensive sealant into the ducts to seal the seams. The company I hired used insulating tape over the seams instead, for a greatly reduced price. The total price difference in their proposal and the company that I hired was about $4500."

"Excellent service and professional work. The only problem was a broken sprayer for which there was no spare that delayed completion. The company refunded our extra hotel night and the owner John LeVan came out personally to ensure clean-up was done correctly and that their work met our expectations. This was also the only company of four that gave an appraisal that provided health and safety information on the product and how ventilation should be performed!!!"

Insulation questions, answered by experts

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

In some areas, insulation companies require a special license, while some states only require them to hold general contractor licenses. Some municipalities may not mandate any license, although you should always ensure a contractor is fully insured. You can use Angi’s license lookup tool to confirm whether or not an insulation contractor you’re considering holds the necessary license for your area. You can also contact the company for information regarding licenses, certifications, and insurance.

EIFS (Exterior Insulation and Finish System) siding can last from 20 to 60 years, with some properly maintained systems lasting even longer. The exact lifespan depends heavily on several factors, most notably the quality of the initial installation and the consistency of maintenance.

Factors that can shorten the life of EIFS include:

  • Improper or poor-quality installation

  • Moisture intrusion

  • Damage from high winds, storms, or hail

  • Damaged flashing and sealant

  • Lack of regular maintenance and unfixed damage

To maximize the lifespan of your EIFS, it is crucial to hire an experienced and qualified professional for the installation. Additionally, regular maintenance—such as cleaning, repairing small cracks or blisters, and having the system professionally inspected—will help identify and resolve issues quickly, preventing long-term damage.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Cellular shades, also known as honeycomb shades, are the most energy-efficient and insulating window treatments. Their honeycomb structure is made of soft fabric that forms layered cell pockets. These pockets trap air, creating a thermal barrier that reduces heat loss in the winter and blocks heat gain in the summer. For even greater insulation, consider double- or triple-cell varieties. Side-tracked cellular shades, which seal the edges of the window frame, can further minimize air leaks and maximize energy efficiency.
