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."

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."

We are general contractors, but we also provide the following services: roofing, room additions, kitchen remodeling, bathroom remodeling, windows and doors and so much more.

"Buyer beware!!! I have never had such a nightmare with this company. Save your money and your sanity. They installed a patio cover for me. It leaked immediately. This was two years ago. For the past two years, they have been out at least 7 or 8 times claiming to "fix" the leaks. The leaks were not normal patio leaks by the way. The leaking has cause 3 of the 4 lights installed in the patio to fail. Every time they come, it's never fixed. The leaks keep getting worse. They never follow up with me, I always have to call them. They do not manage their sub contractors at all. This latest round started just before Christmas 2021, it's now been three months, four visits later. They took flashing off, said they were going to let it dry out and put it back. I didn't hear from them for two weeks, I noticed rain on the weather , I called Trig who had to send them back out to put the flashing back on. They sent some guy to do some more drastic sealing or something on my roof, they claimed it was done.....see attached photos of how they left my roof claiming it was done. Also, never followed back up with me on a light they need to replace which is still burned out and filled with water from rains. Save yourself the headache please!!! This still isn't resolved. I have filed a BBB compliant to try and help me resolve."

Insulation questions, answered by experts

While the answer may depend on who you ask, most contractors would agree that spray foam insulation is a strong candidate for this job as it is effective at repelling moisture and is resistant to biological growth.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.

There are no building codes requiring HVAC duct insulation for ductwork in conditioned spaces, like walls or floors. Unfinished basements are also exempt from this requirement. However, many homeowners choose to insulate their home's ductwork in some or all of these areas to increase the system's efficiency and reduce potentially harmful areas of condensation.

A-frame houses pose specific challenges that can make heating difficult. Their open concept design with high ceilings can lead to a colder lower floor and a warmer upper floor. A ceiling fan that pushes warm air down or pulls cold air up, depending on the season, can easily counteract temperature issues. Additionally, certain types of heating do better in these homes than others. For example, heated floors tend to be more practical and energy efficient than baseboard heating.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures.
