"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."

"I had an extensive rat issue in the insulation under my house. The Crawlspace Crew came over the same day to give me a quote and inspect my crawlspace. They organized the entire job, including removing the insulation, setting up a new barrier, spray underneath my house with an antimicrobial chemical and reinstalling new insulation. They also orchestrated with a pest control company to come and set traps, and close up any holes that were ports of entry for the rats. They were extremely efficient at communicating back with me and Two to the timeline. Overall, I was very impressed with the Crawlspace Crew."

Insulation FAQs, answered by experts

The primary purpose of insulation is to maintain comfortable temperatures in a home, whether that’s cool air when it’s hot out, or warm air in winter, but that’s not all it can do. All options will also minimize heating and cooling needs, lowering both your carbon footprint and energy bills in turn. And some options, like rigid foam boards, even offer soundproofing benefits, too.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

The benefits of insulating your pipes include preventing freezing, sweating, and condensation. In addition, insulating your pipes can make your home more energy-efficient by keeping your pipes from losing or gaining heat. You’ll be able to turn the temperature of your water heater down by two to four degrees Fahrenheit. According to the U.S. Department of Energy, this can reduce energy costs by 3% to 4% per year.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

Although the cost might seem high, winterizing your home is important for your health and the structural integrity of your home. Winterizing will keep your home warm and toasty during the cold months and prolong the life of your appliances, windows, pipes, sprinkler system, pool, and more.
