"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"

"We re-sided our 1929 house recently, and during the tear-off phase it was the perfect time to have blown-in insulation performed to insulate our exterior walls. Ryan and his crew worked quickly and we are so much more comfortable with our walls finally insulated. We had a minor repair needed as a result of the drilling, and the company worked quickly to resolve it to our satisfaction. I will happily recommend them to others, and feel like this project pays for itself quickly in terms of energy efficiency and comfort."

"It went great! Ulises had an immediate opening! The job took about one and a half days. It is done. After 28 cold winters we are now insulated and A LOT warmer. Quieter inside as well. They used blow in cellulose greenfiber insulation in the walls and R-30 in the basement. Yes I would definitely recommend Ulises Pro Insulation for your insulation needs!"

"I contacted 3 companies and they were all wonderful. They came out and gave different bids. They were all very experienced and very good about getting back to me. They were all very helpful and customer oriented. It was only for financial reasons that I had to put off the work. It was for underneath insulation like in a crawl space of the main floor. Only Alpha could do the entire job because of the skill set. They quoted me $1800 and because it was before the end of the year, there would have been a $600 tax credit. So the net cost would have been about $1200. The other 2 quotes were higher on that account. The timing of the work was based on the fact that I had a delay in updating my kitchen. I was hoping that it would be done quickly because they had to have my new sink put in and have all the new plumbing done before they could do the insulation underneath. It was a spray on thing to close up the holes in the bottom of the cabinets which were bigger than the plumbing and breached all the cold air. They were awesome. I will go to them when I have the money to get the work done. As far as affordability, overall professionalism and the fact that they could do the whole job is concerned, they were very good."

"My husband and I bought our house in June 2012. The central AC unit has been working fine, but we don't know much about it (first-time home owners) and we've never had it serviced. Portland is in the midst of unusually long-lasting hot weather so I thought it would be a good idea to have it looked it. Our AC unit would also blow normal air after being on for about 6 hours so we wanted to make sure we weren't doing something wrong. 
    I looked at the deals listed, and called around to many places to see how quickly they could come out. All other places were booked out a few weeks (understandable for summer, especially in the midst of this unusual weather). SunGlow was able to come within a few days. I did call them the next day after I purchased the deal as I did not want to wait for them to call me. 
    The technician arrived on-time which was great. He was very polite. He asked what the problem was and my husband explained to him that we are first-time home owners, we've been using the unit but don't know much about it, and that it occasionally blows non-cold air. He was nervous telling the technician that as the tech could have taken advantage of us and tried to sell us something we didn't need, as we wouldn't have known better. That was not the case, however. The technician kindly took a look at our unit and explained many things to my husband that we didn't know. Things about proper usage and how to clean the air filter. The filter was filthy and he told us how often to clean it/change it and showed us where it was. He also let us know that our unit would blow normal air sometimes because the coil that controls the temperature is pretty dirty. My husband asked if we needed a new one, and the tech said no, not for a long time. He told us that we could clean it, but to also put our unit on auto after about 3 hours of running, let it run on auto for an hour, then switch it back to on, and that would let the coil kind of reset it's temperature. That was very helpful to know.
    He was at our house less than an hour but was very helpful. We did what he said yesterday, and I do notice a difference in the temperature already. 
    We will use this company again in the future for any heating/cooling needs.

Insulation questions, answered by experts

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.

Spray foam is a highly effective insulative material that can dramatically reduce your energy bills and create a more comfortable living space. It does have a couple of drawbacks, however. First and foremost, spray foam insulation is much more expensive than fiberglass batt insulation. In addition, spray foam insulation is a dangerous chemical material; this is a project that is best left to pros for proper and safe installation.

Depending on the item, several different materials are beneficial for long-term storage. Bubble wrap and plastic wrap help ensure delicate ceramics or furniture are safe and secure. High-quality moving boxes made of durable materials like plastic also help ensure the longevity of your storage, as cardboard will degrade faster over time.

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

Air duct insulation typically lasts for 10 to 15 years or even longer, depending on the material and maintenance. It's important to conduct periodic inspections to check for signs of deterioration, such as water damage, tears, or general wear. If you find any of these issues, it may be time for repairs or a full replacement. You might also consider upgrading your insulation even if it's in good shape to improve your home's energy efficiency and enhance your HVAC system's performance with newer, more effective materials.
