Insulation Nation, LLC
Insulation Nation, LLC
Hi there from Dustin, owner of Insulation Nation! Here in So Cal, we join our Colorado office in providing personalized high touch experiences for our customers. I work with our customers directly every step of the way from evaluation, education and review of options, through the project and to inspection of the results. We've never seen less than a 5 star review. Small businesses live and die by reviews and we are ready to earn 5 stars on your project! Thank you! C-02 Insulation and Acoustic #: 1127373 EXP: 10/31/2026
"We had Insulation Nation (Dustin) come to our house to look at our attis insulation; our house was built in the late 70's and I had added more blown-in insulation many years ago. We decided on adding 8" of blown-in insulation to reduce our heating/cooling cost and to reduce the cycling of our HVAC system. They did a wonderful job of sealing any attic leaks, covers for our canned lighting fixtures, built a dam around our whole house fan, added baffles around our soffits, and added the insulation. Nicely done and a professional job. Would recommend using their service."

"Look no further than Verity Build if you want a beautiful kitchen remodel. Verity just completed our kitchen remodel and we couldn’t be more pleased working with this company. The owners Ted & Tony are exceptional to work with. Ted designed our kitchen and came up with many wonderful ways to effectively use our space. He is patient and listens carefully to what you want, making excellent suggestions along the way.

His 3D renderings showed us exactly what the new kitchen would look like, being able to move & change cabinets to look and work best. When the project started, Tony was onsite to make sure it happened according to the plan. Tony closely monitored the crew and kept in great communication with us throughout the process. The Verity crew is topnotch and does high quality work while always being professional, courteous and friendly. The worksite was kept organized and cleaned up each day for the next phase.

Our main goal is to provide our clients with a wide variety of expertise, knowledge, professionals, and outstanding customer service. American Home Improvement is here to help make your home remodeling experience smooth and affordable. $5000 project minimum.
"We hired AHI to remodel 1 bathroom, paint our interior (with some drywall repair), and install recessed lighting in our home. We began work in early April with an anticipated end date of mid June. The cost of the work was in the middle of the quotes we received. Our experience has been horrible and ended in us ending our contract with AHI and having to hire our own professionals to finish the job as of mid- August when it was still incomplete. -They are not good at communicating. I often would have less than 48 hours notice to get them a piece or material needed or less than a few hours notice that some work was beginning or we needed to come meet them. We had to constantly follow up for updates about the schedule and project. -The first paint crew did not prep at all and painted/ texture sprayed over our outlets, HVAC vents, light switches. They left large drips of paint in multiple locations and got paint/ texture splatter on our flat ceilings, on our windows, and all over our subfloor. The project manager from AHI did not oversee the project an the full home was done before he looked at it. He and foreman agreed the quality was not acceptable and took over a month to schedule a new crew. This crew was better but delayed the project significantly. -Our home was left with 1st floor doors and windows open overnight on multiple occasions. We do not live at the property at the moment but our belongings are there and though we pointed this out to the project manager it happened again. -The crews sent were not managed well- it felt like we got below handyman level quality of work in many areas. In addition to the paint crew they sent someone to paint our bathroom baseboards and he painted all over the wall. The electrician left screws and debris all over brand new wood floors and managed to scratch them plus scratch our new marble in the shower. -They drank beers from our fridge multiple times and left trash all over our home and in front of the house overnight/ for multiple days. We ended the contract with them completely unsatisfied but amicably coming to a financial agreement that settled it. I would strongly recommend that you do not hire AHI unless you are ready to manage the project yourself and be there to supervise their subcontractors as the work is done."
