"JR Insulation is a great company!! They did everything from start to finish as promised, on time, polite, clean, and on budget. I can't recommend them enough. They also fixed a problem that I created in my own ignorance for free just to make me even happier. I told them it wasn't necessary but they insisted. JR's pricing was the absolute best for everything they did. Not the lowest bid but the lowest price to value, which in my opinion is the lowest bid. I would use they again, in fact, I would not use any other company for insulation or dry wall. Brian"

"Had vapor barrier replaced, insulation put in floor/attic, and duct work sealed/insulated. Ryan came out to bid and did a great job explaining everything and answering all our questions. The crews were all professional, polite, & respectful. Showed up on time every morning and went over the days work scheduled. Plastic off all work areas & cleaned up everyday on the job. No sign they were their that day. The quality of the work was excellent. Very impressed from start to finish."

"Would recommend to anyone! Ulises Pro Insulation, LLC were great advocates for their customer's best interest. My attic space was under-insulated. They did a careful inspection of the space, and showed me photos of their findings. They were honest about there being no urgent issue, and about what might be limitations of working in such a tight space. Nonetheless, they were happy to attempt the service and were able to maximize the space's energy efficiency. They were fast to give an estimate, fast to schedule and complete the job, and they left the workspace spotless."

"Juan of Timberland Insulation did an outstanding job. We had critters get into our crawl space where they ran amok all through our insulation. The old insulation had to be removed and new insulation installed. The crew at Timberland out performed my expectations. I would highly recommend them."

"Westside Drywall was the only firm willing to do what I requested, which was to repair and not replace under-floor insulation. As a result, their price was much lower. An added bonus was that they could schedule the job in a few days instead of a few weeks or months."

Customers say: True professional

"They did a very thorough crawl space clean up and detailed and well secured installation of the vapor barrier . They were honest, and efficient with positive energy. The issues are with communications from the office. They could be more professional, timely and thorough."

"Pablo did a fine job. He insulated two south facing bedroom walls. He showed up on time and worked hard. There were several challenges. My walls had a “whisper” of insulation. Enough to require something special. And he had a solution up his sleeve. And one of my bedrooms had walls with unique paint features that I requested that he work around. And he did. After insulating the walls he had to spackle the drywall. He spackled, let dry, sanded, and repeated the sequence. He came back the second day so the walls would be really dry. This was followed by texturing. I painted the next day and I can’t even tell that 24 holes were created in each bedroom. Fantastic. Pablo is the owner of Call of Duty so sometimes it was hard to connect but everything worked out super. I was really impressed with his attention to detail. I would use him again."

Insulation FAQs, answered by experts

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

Selling a house with spray foam insulation can be challenging due to concerns about improper installation or its compatibility with the home's structure. If not applied correctly, spray foam can cause issues such as moisture buildup, cracking, or damage to wiring and plumbing. If the insulation didn't cure correctly, there are also flammability concerns. Removing or repairing this type of insulation can pose risks as well.

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.
