"We had astronomical winter heating bills in the first winter in our new (old) home. I hired Shane and his team to install a vapor barrier in my crawlspace, insulation in my basement and to replace my crawlspace doors which were deteriorated and lacked insulation. The quote process was thorough but quick. They scheduled the work quickly as well. On install, they literally unearthed a mountain of construction debris that had collected under the house for who knows how long. They completed the job in just a couple of days and the results were more than impressive. We also chose to replace our windows and the result of both jobs brought our energy bill down by more than 50%. All-in-all we were thrilled with the outcome of the work with Managed Services Group and would highly recommend them to others. Priced fairly and flexible on scope. These guys just get it."

"Bill knows what he is doing and holds himself to high standards. We wanted to upgrade the attic, and when he left, we have insulation carefully and well placed and blanket over the access. I'm very satisfied. This attic is now really well insulated, he did a little caulking around the access stairs, came on time, got done a little more quickly than he had estimated, and everything nice and clean."

"I think they did it all in one day. When we decided to go with them. We have one room that doesn't have a second story with recess lights. That room is fairly new, we put it in 6 years ago. He showed me pictures of stucco in there. All those lights were coming in through those recess lights, they were not properly caulked or insulated, so we were losing a lot of beautiful energy through those recess lights. He corrected that. He correct where some of the baffles were covered. He brought it up to high lighting. There was a giant antenna laying across the top of the attic in the main house doing absolutely nothing. They broke it up and removed it. I felt like they were my eyes and ears going up there, something I couldn't do and showed me things that were done incorrectly.  The original insulation was a bluff. It had been displaced. I actually had ceiling drywall in between the structure. They corrected it all. Even the ceiling access was properly insulated and closed. They are just very thorough. They helped us when they troubleshooted from the old company. The price seemed perfectly fair, they didn't try to sell you a cheap product with a cheap price. It seemed like a fair price in line with quality. That's all we really want."

"They arrived, spread plastic over the floors, stairs, and hallway.  They went into the attic and began repairs and caulking.  Once completed they spread the existing insulation, then added cellulose to proper level.  The installed the attic blanket and cleaned the area.  Great job, explaining what they were doing and asking if I had any questions or concerns.  Superior work."

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

A plastic vapor barrier should completely cover your basement to prevent water from penetrating through the walls. This typically goes before installing insulation to prevent moisture from building up and becoming trapped on the inside of your insulation, where it can collect and lead to mold damage. Installing insulation after the vapor barrier allows for any moisture to exit the walls for better ventilation.

You should not use spray foam insulation in several specific areas. Avoid applying it in spaces exposed to high temperatures, such as near electrical boxes or recessed lighting, unless the foam is specifically rated for such use. Applying foam near electrical boxes can damage the wiring, and using it too close to lightboxes or recessed lights creates a potential fire hazard. Additionally, do not use spray foam in areas prone to shifting or movement, as this can lead to cracks and gaps in the insulation. Finally, open-cell foam is unsuitable for use below ground or in areas exposed to moisture because it can absorb water, which compromises its insulating effectiveness.

It’s technically possible to install loose-fill cellulose insulation without a blower, but it’s much more time-consuming, tedious, and dangerous. You’ll need to wear the proper protective coverings to handle the cellulose after it’s been doused in boric acid; use a shovel when you can to transport the material from the bag into the wall cavity.

That said, if you purchase cellulose materials at a home improvement store, ask if they rent out blowers for free or at a discounted rate. In many cases, if you buy the material from the store, they’ll rent out the blower at no extra cost.

The level of insulation is determined by both the material and the thickness of the door. Some garage door materials (such as wood) have natural insulating capabilities, while other materials (such as metal) do not. No matter the material, two-layer and three-layer garage doors have a higher R-value than single-layer garage doors, as insulation is fitted between the panels. 

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.
