"It went great. Two workmen were under the house most of the day, on their backs in the crawlspace. They marked electric lines and pipes on the face of the foamboard, and they used screws for installation so that boards could be removed if necessary for service above them. They were clean, professional, polite and friendly. The price was very reasonable for the work they put in. Description of Work: They installed 1" foamboard on the batt-insulated ceiling of the unheated crawlspace under my house. It reduced drafts substantially in the first floor. They also built frames for my attic stairs and my whole house fan from foamboard, to reduce heat loss. Services Performed: Yes Cost: $1,700 Work Completed Date: 11/27/2018 Hire Again: Yes"

"Great Company! I highly recommend PEC if you are interested in upgrading the insulation in your home. They gave a highly competitive bid for adding 10 inches of insulation to my attic and installing a new bathroom exhaust fan. They also vented two bath exhaust fans and one kitchen stove exhaust to the outside. What a difference that has made. Today is a 95 degree day and before the insulation upgrade the Air Conditioner could not keep the inside temperature at a constant 72 degrees and often rose to 75 or higher and the Air Conditioner ran all day long. Today it's 92 degrees outside and the Air Conditioner is seldom running to keep the inside temperature at 72 degrees. The entire team at PEC are wonderful to work with. They are extremely courteous, polite and hard working. You don't find those attributes very often. Larry, Imperial Missouri"

"Estimate./proposal done by Bryan. Knowledgeable and professional. Did have to reschedule appointment due to equipment problem on a job prior to my estimate. Scheduled the work with office staff (Chris) for a couple of weeks out. Got a call the afternoon before installation that they would need to move to the next day due to having to stop an attic blow in install because of rain. Very apologetic. Bryan and Tammy arrived a bit later than scheduled due to back up at the warehouse where they were picking up the spray foam tanks. Bryan and I walked through the job and made sure we both were fully aligned on the areas to be insulated. Job went smoothly and was done professionally. He did a good job of covering under a bay window to be sure it was fully insulated. Cleaned up the area very well after they were done. They use a fully automated system to schedule and sign off on the contracts. You will need to be somewhat capable technologically through smart phone, tablet or computer."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Fenton, MO

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.
