"Quality experience from my initial inquiry, to estimate and Tech's explanation of each and every step that they would provide to insure the best job that could be done and for the installation. All three installation workers, that worked on my house, were very professional, very knowledgeable and each took pride in the work they were performing. This was was a full attic insulation, including removal of old and replacement of new, and basement sill plate sealing of a 100 year old home. They politely, and with enthusiasm of their craft, answered my questions about what they were doing, why and how, which just confirmed that I had made the right choice to go with Mincin."

"Bob and his team were great. Bob gave honest advice on the best option to insulate my attic and crawl spaces. The main issue we had was our infants bedroom which had brick walls and 2 windows making it very drafty. While the insulation made a noticeable difference overall, our sons room was still a bit drafty which we expected due to the brick outer walls. Still worth every penny."

"I highly commend this company. Unfortunately I could not have them do the job. He came out, on time, to give me estimate on insulation. He was very honest with me! To do this Job would have required me to have additional projectsâ replace aluminum siding, and holes would be in paneling which was wallpapered over. I am recently widowed and will probably be downsizing in few years. Rather than spending money and doing other projects, decided not to do it. Most companies would have said â oh yes, we can do thisâ and them made a mess! Itâ s nice to know there are still decent, honest companies around."

J and V Roofing has professional and polite crews that know exactly what needs to be done for each step of the job. Owner John Valentino worked along side his crews. They had to work around rainy weather conditions so the job took a bit longer than anticipated.  The time period was 3 weeks.  They made sure the open roof was protected with tarps from rain that occurred at the beginning but wasted no time when the weather broke for the better. The job entailed removing insulation and plaster from the old ceilings of two bedrooms before new insulation and drywall could be installed and painted.  The crew and owner John Valentino checked and measured all beams before new insulation and drywall were installed. They worked carefully to correct or match old angles in the ceiling.  Each crew took care of clearing their mess. There were insulators, carpenters, window installers, dry wallers, sanders and painters. John Valentino was polite, knowledgeable, provided patience and was friendly to our family during the ordeal of renovating, as was his crew.  I would highly recommend J and V Roofing and Home Improvement!  As a side note:  The City of Warren Building Dept. and inspector, however, lacked professionalism.

FAQs for insulation service projects in New Castle, PA

Old insulation should be removed when it shows damage, contamination, or heavy deterioration. If you notice water stains, rodent droppings, mold, or large gaps, plan on taking it out to protect your home’s energy performance and indoor air quality. Removing compromised material eliminates health hazards, cuts energy loss, and sets the stage for a safer, more efficient attic—all while keeping utility bills in check.

R-value measures how well insulation resists heat flow—the higher the number, the better it slows heat transfer. The right R-value keeps your home warmer in winter and cooler in summer, saving energy year-round. Match the rating to your climate zone and have a pro verify performance over time, because moisture or settling can lower R-value and cut efficiency.

Attic insulation can stay in place for 80 to 100 years, but its performance often drops after the first 15. As dust, moisture, or mold build up, the material loses R-value and allows heat to escape. Schedule periodic inspections so a pro can tell you when replacement makes sense—helping you keep energy bills down and indoor comfort up.

You can over-insulate an attic. Beyond the recommended R-value, extra layers don’t add efficiency and can trap moisture, leading to mold or reduced performance. A local insulation pro can measure current levels, confirm the right target for your climate, and advise on any adjustments so you avoid future energy or maintenance headaches.

Insulation can be damaged by mold, pests, water leaks, or accidental electrical contact. When the material is compromised, it loses R-value and can introduce health hazards. Removing and replacing affected sections restores efficiency, while routine inspections from a qualified pro help you catch problems early and keep your attic safe and energy-smart.
