"Jose and Jorge are top notch, I would highly recommend for your insulation needs! From beginning to end they are very quick and responsive…from the estimate, to getting scheduled, and getting the work done. I had several quotes from different companies, and some of the other “5 ⭐️ “ companies (top of the list when you google search) tried to upsell sell me, and were nearly double the price. When Jose did my estimate inspection, I asked about some of the items the other guys were trying to upsell me on. Jose insisted I didn’t need some of the items trying to be upsold to me and explained why (even though J&D offered those services). Lastly, my job ended up requiring more insulation than initially thought, and Jose honored the price he quoted, he didn’t try to bait and switch me on the price. If you’re looking for top notch work, at a fraction of the price of the other guys, don’t hesitate to book these guys."

We are extremely passionate about the work that we do. You can depend on us to provide a high quality service at a fair and honest price. Customer Service is our highest priorit and we provide a Free estimate! High Energy bills and Comfort issues can be directly attributed to a lack of Insulation and a leaky uncomfortable home. Since we are Building Science Gurus, we can directly fix Air leakage Issues using Blower Door directed Air sealing (Weatherization) with non-toxic low VOC caulking, sealing light cans, outlets etc....contributing to overall leaky home. In addition, most homes built 15-50 years ago are all lacking the proper insulation needed to have low utility bills and comfort issues Cellulose insulation is the most energy efficient attic insulation on the market! Giving a higher R-value per inch than fiberglass and air tight. We test homes before and after will provide 30-40% more air tightness than fiberglass.

"Happy with the overall time spent and work done and the results of having new insulation. A definite improvement."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Denver, CO

Batt insulation excels in vertical installations because it remains firmly in place and delivers consistent thermal performance. Blown-in insulation performs exceptionally in spaces such as attics, efficiently filling gaps in irregular areas. 

Employing both insulation types according to their strengths enhances your home’s overall energy efficiency and comfort by providing a tailored solution for every space.

Start by measuring the square footage of the space, then match that area with the insulation thickness you need to hit your target R-value. Add a buffer for waste and odd-shaped spots so every cavity is covered. 

Once you have a rough count, run it past a local insulation pro—their on-site advice will fine-tune the numbers and help you avoid costly miscalculations.

Old insulation that is dry, intact, and mold-free does not require removal before adding new insulation; stacking new insulation over it maintains effective thermal performance and boosts energy efficiency. 

If the insulation is damp, moldy, or deteriorated, removal is necessary to eliminate health risks and ensure maximum effectiveness of the new layer. A professional insulation contractor will assess your situation and recommend the most effective solution.

Installing insulation in an average-sized home using batts or boards requires five to 12 hours. Using spray foam or blown-in insulation requires two to five hours. These timeframes are determined by the area’s size, accessibility, and whether old insulation must be removed. 

Complex projects and hard-to-reach spaces demand extra time. Hiring an experienced insulation professional ensures that the installation is completed efficiently and correctly.

Insulation is measured by R-value, which defines how effectively it resists heat flow. A higher R-value provides superior thermal resistance, ensuring your home remains warm in winter and cool in summer. 

Choosing the correct R-value is essential for maximizing energy efficiency and comfort, and it directly impacts long-term utility savings. Professional guidance determines the optimal R-value for your specific climate.
