"I had old asbestos insulation in a new house that we were moving into that we wanted removed and replaced. Dakota was quick to respond, come out to do a free quote, schedule and execute. I was worried that it would be expensive due to it being hazard cancer causing materials. But he had everything he needed to get it done quickly and safely and affordable! Amazing job!"

"It was a small job. They sealed the vents to the crawlspace, then, since there was already solid insulation panels on the walls, put a vapor/moisture barrier, in the form of a tarp, 4 feet wide and as long needed, completely around the crawlspace. It was then sealed to the walls with "nails" and adhesive. This seals the wood frame of the house from the 'Outside", the ground, which is the floor of the crawlspace. A 20 mil thick, quite heavy, "floor" was installed, also in the form of a tarp, It went up the walls about 3 feet and was taped to the 'tarp" on the walls, using a tape made for this application. The piers were wrapped with the same stuff and taped to seal the inside from the outside. the "floor" is also a vapor/moisture barrier, but, heavy enough to walk on if needed. This basically makes the crawlspace another room, rather than the outside. Our house is one year old and was already getting mold on the floor joists. Since the air in the crawlspace will now be heated in the winter and cooled in the summer, just like the rest of the house, the mold and cold (52 degrees) floors we experienced last winter will hopefully be eliminated. We shall see when dumb winter gets here."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Dennison, IL

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.
