Jack did a great job replacing the insulation in my crawlspace. He was great with communication and scheduling and made things easy. Great quality work as well. Thank you!
I’d like to personal thank Jack and his crew. They came out and insulated my house after it had flooded and had lots of storm damage. Jack responded to me in a very respectable timely manner once I called and I had my free estimate for all the work that they were gonna do to my house in under 24 hours. For that I’m very grateful most other company’s told me that it would be a week to almost two weeks out. Once I received my free estimate they started work on my house the following weekend. I highly recommend coastal insulations to any everyone looking for insulation work. Thanks again Jack and your crew for all the amazing work that y’all completed for me.
They did our crawl space for a 6000 sf building and did an awesome job. They pulled out all the wet insulation and replaced it as well as the vapor barrier. Very good would recommend.

Rob and Chris did a great job. They installed a whole attic radiant barrier and added blown in insulation to take out attic to R38. They were efficient and clean. I highly recommend Koala insulation.
The crews that came out to insulate my attic and install my solar fan were great. Scope of work was discussed prior to it beginning and my input was solicited prior to placement of the attic fan. The crew was also very accommodating of the crowed work site as I had several trades on site at the same time. I’m very happy with the results.
Koala was professional and responsive from quote to installation! They were able to accommodate my quick timeline and the installers, Cody and Jeff, were prompt, polite and professional. They explained the process and got right to work blowing insulation into my attic. When finished, they cleaned up and showed pictures of the finished work. Highly recommend!!

Amazing! I can’t say enough about how great the team was! We’d had a previous encapsulation done by another company and weren’t happy with the work. We did some research and found Crawlspace Ninja and gave them a call. I initially spoke with Jennifer- she was knowledgeable, answered my initial questions, scheduled Mike to come out right away, and as a follow up to our convo she sent me a link to their educational videos! Mike came out, and even took the time to crawl under the house with my husband to explain the services they could provide. Afterwards, Mike handed us off to Steven (whose team did the work) via a face-to-face meeting and walked us through what to expect. Mike and Steven both reached out weekly prior to beginning the project to check in. Once the work started - Steven, Cameron, Matt and Caroline delivered superior service! Each morning they arrived on time and meet me at the door to walk me through what they yAmazing! I can’t say enough about how great the team was!

Each morning they arrived on time and met me at the door to walk me through what they had planned for the day and what time they’d wrap up. Each evening they’d meet me at the door again - to tell me what they’d gotten done, what they’d be doing the next day, what time they’d get started, and answer any questions I had. Once the job was complete - Steven took the time to crawl the space with my husband to ensure that all work on the final checklist was complete and met our expectations. You just don’t get this kind of service these days. They truly exceeded our expectations. Highly recommend them - trustworthy, great communication and high quality workmanship!
From Jennifer in the office, to Cody, helping to coordinate the entire process, to their entire crew - Cameron, Steven, Doug, and Jaden, They did an amazing job. Our crawlspace looks brand new and the mold seems to be completely gone. Hopefully this does the trick and gets our family completely healthy. Would highly recommend these guys. Thank you!
Crawl Space Ninjas of Wilmington is the best investment we could have made for our new home. Steven and Cameron were meticulously thorough and unsurpassed in their craft! It was world-class service, start to finish. By installing a water management system, ventilation fans, a condensation pump, a sump pump, removing all mold, and encapsulating our crawl space, they have prolonged the life of our home. They’ve also preserved the equity of the house if we ever sell. If you’re considering encapsulation, hire the Ninjas… you won’t regret it.

They were great! Did a very thorough job of insulating the attic - in compliance with Duke Energy rebate plan. They were thorough but quick, better than the other 3 companies using more insulation than the others and at a lower price even though they provided radiant heat barriers for all knee wall and attic access doors. Communication was excellent with them and they handled all forms needed by Duke for getting my rebate.
Chris and company helped us out when we first moved here in 2013. Installed energy efficient wrap in the attic. Over next few years All About Energy Solutions has installed energy efficient lighting, protective wrap in crawl space, and extra insulation in attic. Chris and crew are knowledgeable professionals. They stand behind their products and have repaired or adjusted what they installed without any extra charge.
A few months ago, we started to smell a musty odor in our house. I had a handful of contractors look at the crawl space to determine the source of the smell. One heating and air company said I needed all new duct work. Another said I did not need any duct work replaced. I had three insulation companies look at it and it turns out the smell was coming from some wet insulation caused by a since-replaced water heater. Chris also noted some evidence of past animal activity under the house which also led to some of the smell. Chris suggested I replace the insulation, fog the crawlspace with a disenfectant and add a new vapor barrier. So far that approach seems to have done the trick. His estimate seemed fair for the scope of work proposed. I want to commend Tammy for her good communication skills and his crew of Terrance and Canaan. They were professional and courteous. I would recommend All About Energy Solutions to my friends and family.

We had gutters installed by Blown Rite and Kris was on top of it! Personal and professional, work was completed quickly and we are very pleased with the finished product. I work in the construction industry and know how hectic it can be, they made us feel like we really mattered. We would recommend them to all my family and friends.
We added oversized gutters and gutter guards based on their recommendation. They also added insulation to our attic. The products delivered are outstanding; service was excellent; and the people are super professional and efficient. Both jobs were completed quickly and when finished they took all the trash with them. Their pricing is extremely fair. If you need gutters and/or insulation you don’t need to look further. Blown-Rite for insulation and gutters get 10 out of 10 stars from us. Thank you Kris and Blown-Rite.
We are very satisfied with Kris and this company. Kris is great with estimates, very afforable. Workers were professional and on time with doing our insulation. My husband and I highly recommend Blown Rite.
