"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."

"We had a small job to remove/replace insulation that may have been soiled in our attic from a squirrel that got up there years ago. It was mentioned in our home inspection. After going up to take a look, Sean explained he didn’t see any soiled insulation but there was a small area that had been moved away from the corner and it was effectively empty. It was really too small a job though to warrant them coming out to blow stuff in so he recommended just taking a leaf blower up there to redistribute it evenly. Brilliant idea! He also graciously took a look at our crawl space and identified some areas we should address but ones we could do on our own. He was great to talk to and very helpful and reasonable. So nice in these days of everyone trying to upsell everything. If and when we need insulation work, we’ll be calling Dr. Energy Saver! Thanks so much, Sean Becker!"

"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."

"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

Most heat in a garage is lost through air leaks in windows, doors, and walls. This is especially true if the walls are uninsulated, which is common in garages. Consider insulating your garage before installing a garage heater to ensure the heat it generates isn’t wasted, making it less efficient.

Yes, including recycled denim and cellulose from natural fibers.

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.

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.
