"Everything went according to plan. Crawlspace insulation was replaced and closed space was sealed up. A air inducer was also installed. The environment is totally different down there now and is much closer to the temperature of the house. I kept my vapor barrier the same."

"Insulation Commandos insulated my garage drywall, and I had a great experience working with them. Tony was especially helpful in explaining the available options and recommending the solution that best fit my garage and specific needs. He was knowledgeable, professional, and even managed to fit me into his schedule on short notice, which I greatly appreciated."

"I recently had Home Shield install new insulation in my home, and I couldn't be happier with their work! From start to finish, they were professional, punctual, and efficient. They arrived right on time and completed the job in a timely manner without cutting corners. What really stood out to me was how clean they left everything. They made sure to clean up thoroughly after themselves, which is always appreciated. Additionally, their expertise was evident—they not only knew exactly what needed to be done but also took the time to explain what steps we could take to keep our home warm during the colder months. Overall, their excellent service and attention to detail exceeded my expectations. I highly recommend them"

"I hired Carolina Crawlspace Services to completely clean out the crawlspace under my townhome, remove all of the old insulation and vapor barrier, and install new insulation along with a stronger, higher-quality vapor barrier. I received estimates from four other companies and chose Kyle and Carolina Crawlspace because their pricing was competitive, included more work than the others, and was slightly lower overall. Kyle communicated clearly throughout the entire process, arrived on time, and did a fantastic job. The quality of the work and professionalism exceeded my expectations. I would highly recommend Carolina Crawlspace Services to anyone who needs crawlspace work done."

"This company is a top notch operation. From the moment they arrived at my house for our first meeting to discuss my repair needs to their finished project completion they went above and beyond to fix and clean up what a previous company did not do properly. Their employees are hard working and very professional. The work they completed under my house of cleaning mold from under the crawl space was more than stellar, which the previous company that started left me in a mess and never completed. They installed insulation and a beautiful floor barrier. Going above and beyond was installing a dehumidifier under house for one month to ensure absolute drying of floor joist and entire area. they did this as an added precaution for me the customer which shows true customer service and what a 5 star company is all about. I cannot say enough good things about this company and Tim Koons who represents it with wisdom of the business and a professionalism that adds trust and confidence to the customer. Nancy Hill, Clayton , NC My second review for this company also goes above and beyond what any other company has offered or done for me , the customer. They installed a dehumidifier under my house for several months free of charge to insure under my house was completely dried out to ensure new insulation and mold treatment they did would not be compromised in any way due to moisture and cold weather. This company is a top notch company that puts the customer as there number one priority. They took care of all my needs and went above and beyond for me. I would highly recommend them to family and friends."

"Jimmie was professional, friendly and knowledgeable. Of the estimates and recommendations I received for mold remediation in my crawlspace, I thought Jimmie's approach seemed the most logical and thorough. Pricing was fair, and the service was prompt with regular communication from him and his team about progress and next steps. He even performed an extra preventative measure that wasn't included in the estimate. I highly recommend this company."

FAQs for insulation service projects in Raleigh, NC

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
