"I can't recommend Koala Insulation enough for its outstanding service and expertise in blown-in insulation. From the very beginning, my experience was exceptional. The customer service (Tiffany) was incredibly helpful and informative. She answered all my questions patiently and thoroughly. When the Consultant came out he explained the different insulation options and recommending the best solution for my needs. Scheduling the appointment was a breeze, and they were flexible and accommodating. The technicians who arrived for the installation were professional, courteous, and knowledgeable. They took the time to explain the entire process beforehand and answered any questions I had. The quality of their work was outstanding. They were meticulous and efficient, ensuring all areas were properly insulated. They also cleaned up thoroughly afterward, leaving no mess behind. Overall Experience: I'm extremely satisfied with the entire experience with Koala Insulation of Eastern Carolina"

"Sales rep, Tommy, was thoroughly entertaining while he explained the "basics" of roofing and the options available through CRC. He was very informative and confidant in their products and even suggested some tips on getting other proposals. I shouldn't have wasted my time with the "others", which were considerably less informative, more "pushy", and not really any less expensive (one of the "big name" competitors was actually a substantial amount higher).

The install process went extremely smoothly; the crew was on-time, very polite, and very efficient. The install supervisor kept me informed every step of the way and fixed some minor problems related to some hidden wood rot and documented everything with pictures (I wonder whether the competitors would have simply covered it up and left it to worsen???)

I expected to find pieces of shingles or nails around my house or in the landscaping but there was not one single scrap and absolutely no evidence of them being there except for the great looking new roof!

During the follow up visit to make sure I was completely happy with their roofing services, Van and Tommy mentioned that CRS also does attic insulation. After another educational description of the process, I accepted their very reasonable proposal and 2 days later the attic was insulated with no problems and absolutely no mess!!!

A few months have gone by and I'm extremely happy with both the new roof and the attic insulation!

The house is noticeably quieter (no more pitter patter of squirrel feet!) and I have already enjoyed a reduction in the heating/cooling costs since the HVAC system doesn't need to run as hard to keep the inside temp constant.

Many thanks to everyone at CRS for making this a pleasant home improvement project!

"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."

"It went very well.  Brian & Sara kept in contact with me to ensure everything was going well, mostly by text which was great and convenient for me.  One crew did the roof and another crew did the soffit & fascia.  I have an old house so there were some areas needing unexpected attention which Brian was quick to point out and ensure it was fixed.  After the roof was complete, we had several days of rain.  At the time of the massive rain storms,  I was not living at the house but when I stopped by I seen the roof windows had leaked water onto the floor, I called Sarah and she sent someone over within an hour of my call.  The roof has not leaked since.  Both crews were professional and friendly.  Once I am able, I hope to have windows put in.  I of course plan to shop Angie's List again and have several estimates, but I have a feeling that I will be sticking with Brian & Sara.  Thank you Atlantic Coastal Enterprises.

Insulation FAQs, answered by experts

Unfortunately, pipes can freeze when exposed to prolonged freezing temperatures, whether or not you have installed insulation covers. Insulation covers, however, are still an excellent idea as they can reduce the chance of your pipe freezing by keeping the pipes closer to the temperature of the water inside the pipe.

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

Yes, cladding can help insulate your home by adding an additional layer to the exterior walls, which can minimize heat loss and enhance energy efficiency. However, it's essential to select cladding materials that include insulation for optimal results, as cladding without built-in insulation won't make nearly as much of a difference.

Garage doors that are not insulated can be a major source of heat loss. That’s why it’s essential to winterize your garage door with insulation and weather stripping to prevent heat loss and keep it warm more easily. Consult a local garage door installer if you need help determining the cause of your garage losing heat.

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.
