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!

"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."

Remodeling as it should be. Ted and Tony have one vision in mind; a customer focused, hands-on approach to home remodeling. From the early stages of a concept to the final details of construction, our goal is to create a positive experience. We understand that no two customers are exactly alike, so we take the time to create solutions that appeal to your personal tastes and fit your budget. We offer two basic approaches to bathroom remodeling – Semi Custom and Client Inspired designs. Check out our website for further information.

"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. He accompanied us while we shopped to choose the appliances needed as well as the tile, backsplash & countertops. 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. The project was completed on time and Ted, Tony, and office manager Jennifer were readily available to answer questions and follow-up on any detail that needed attention. We look forward to working with the Verity crew again when we are ready to move forward on our bathroom remodels."

Tal Mechaly was amazing at selecting all the paint colors combinations and with his design… he was able to pull it all together as one piece of art kitchen. Tal Mechaly was very easygoing person to work with, with excellent creativity skills and his thinking outside of the box ability was beyond believes."

"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."

Insulation questions, answered by experts

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

Expect your home insulation project to take between five and 12 hours to complete on average for batts or boards and two to five hours for spray foam or blown-in insulation. It might take longer if you need to remove your home’s existing insulation, you have a higher-than-average square footage, or accessibility is limited.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

It’s best not to install a radiant barrier directly under insulation because it requires an air gap on at least one side to work properly. Instead, you should install the radiant barrier over your existing insulation to create an air space to reflect the radiant heat.
