5 star experience with Irvin and N&J Insulation. He went above and beyond to make sure the attic was clean, sanitized, and properly sealed before adding new insulation. I highly recommend Irvin and his team!

When working with a lot of home improvement professionals, the main way a lot of us judge them is with communication – if I could inspect & assess the quality of the work with my own eyes, I probably wouldn’t need to have someone else do the work for me. I recently had the insulation in my attic replaced because the upstairs was much warmer than the ground floor, and after this work was done, my upstairs does feel cooler, so 2 stars for apparently doing the actual work. But wow, what a pain to get there. After Terra did an inspection of my house to serve as the baseline for a Pepco savings program, the report they provided me included a "health and safety concern" that said "whole house ventilation system does not satisfy ventilation requirements." When I asked for clarification, I was told that there was a typo on this report where the math was done as though my house was 2 feet tall instead of 20 feet tall. Though this simple typo is an easy fix, they never provided me with an updated copy of the report, and that should have been my tip that these guys have a problem with attention to detail. While doing the work in my attic, the team stepped on and broke a ceiling fan bracket, causing my bedroom fan to crash to the floor. I spent that afternoon finding pieces of broken glass under the furniture and in the rug. Additionally, they blew sealant foam into both of the exhaust fans to the upstairs bathrooms, breaking both of them. I was told that a manager would call me by the end of the day to discuss repairs, but that never happened. If destroying 3 out of the 5 fans upstairs wasn’t enough, the workers left their used face mask dangling on a branch beside my front porch. The following morning, Terra charged the balance of the work to the credit card I’d given them for the deposit, but did not call to discuss repairs. When I called, the manager said he was unaware of any damages, but that, again, someone would call me back. They of course didn’t, and when I called them that evening, the manager had no apology and instead suggested that the ceiling fan falling was due to a “faulty installation” rather than damage from his team. He backed off from that when I pointed out the additional damage to the two bathroom fans, but nickel-and-dime argued over a budget for me to go purchase a replacement fan and have it installed on my own. Terra scheduled a date to come repair the two damaged bathroom fans, then canceled that morning without a reason. After a week of no communication, I again started asking when this repair work would be complete, and was told the soonest they could get to me was in 2 weeks, but that they’d “put pressure on the ops manager to do it sooner.” After this entire pain was completed, they did the post-repair inspection for Pepco, and had me sign off that the work was done. Several days later, I was asked to re-sign the document because of a typo – apparently, they never bothered to correct the one from that original inspection document. Despite having “insulation” right in the name, these guys don’t do their own insulation work, they get unsupervised subcontractors to do it, without any feedback or quality control. They’re very prompt with their charges, but not at all with their problems.
