"The evaluation and the subsequent insulation work went fine. Guy clearly knew their stuff and did a good job. Punctuality was an issue. First date for Eval was missed entirely, the late for second appointment. On day of insulation work they were late and could only do half the job since their spray foam unit wasn't working. Came back next day to finish."

"Noah and Victoria just finished removing our 46 year old inefficient, dirty, rodent dropping infested insulation. They vacuumed up all the dirt and droppings in the attic, installed baffles at the soffits, sealed up any air leaks and then installed new R- 38 insulation batts. They were very professional putting down tarps and plastic to protect our floors, then vacuuming afterwards and hauling away all of the debris. Noah called me Thursday after I requested an estimate, came to give us the estimate on Saturday and arrived on Tuesday to do the job. My husband and I highly recommend them."

"I contacted JA drywall to work on some popcorn ceilings for me. Josh was very responsive and arrived on time to give me an estimate. To his credit, he did inform me that his estimate would probably be higher than other estimates I would receive. I decided to go with Josh because I felt he was honest, how he communicated with me and because he was available via telephone. Unlike other drywall contractors, who did not show up or were very flaky with the communication. Josh started the work on time and finished when he said he would be complete. Josh did a great job with my ceilings. The drywall was installed, taped, and sanded. I was very impressed with the work they did and I would absolutely hire him again. If you’re looking for drywall to be completed, Contact Josh and then call other companies and you’ll see the difference in communication. A+ in my book."

FAQs for batt, rolled or reflective insulation install or upgrade projects in Trenton, NJ

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.
