On Wednesday Axel walked me through the whole process a couple of times. He immediately won my confidence and I signed up to get the job done by Rywen. I could not wait for the work to start. The team of workers arrived Monday morning as per agreement - they displayed nothing but professionalism as they prepped the house with paper walkway and plastic tunnel leading to the ceiling opening. Like clockwork the old insulation was sucked out and new insulation laid down piece by piece and secured. In the unfinished basement, where rat infestation was evident, all the junk piled up over more than three decades was removed and hauled away. The foundation and walls cracks were sealed to keep mice and rats from entering the premises. The kitchen was thoroughly inspected for cracks in the walls and cabinetry. Where necessary, cracks were treated with the application of sealant and or with wire mash. I am confident I made the right decision to go with Rywen. I highly recommend them.
Rywen Insulation is an excellent company! Every step of the way was thoroughly explained and completed in a professional manner. Axel did the initial inspection, Walter led his team with the job of replacing insulation, disinfecting and rodent proofing and Roni was super helpful with an electrical issue I had. Everyone at the company was pleasant, knowledgeable and patient with my questions. I highly recommend them!
I was very happy with Rywen’s customer service, communication, and attention to quality. I was especially impressed with their suggestions, for example, ensuring we got the desired thickness of insulation in the attic, overall, plus providing my desired amount of future access. To me, it felt like the company has a consistent attitude of going over and above and that’s rare. Thanks!

So glad that we finally had the attic insulated. The gentlemen were very knowledgeable and worked like clockwork to clear the debris from a previous roofing job. The clean up was thorough and only took a few hours. So far I can feel the difference as there aren’t any drafts. We will see how our utility bills look over the winter and how warm the house feels now that the weather is getting colder. We have a PSEG weather assessment scheduled. Look forward to their feedback as well.
Before hiring Atticare, I spoke with three other companies, and none of them felt as organized or knowledgeable. Sean the technician was great, and walked me through every step of the process and answered all my questions without rushing me. The price was fair, transparent, and exactly what was promised — no surprises. The rodent work was done professionally and the team clearly knew what they were doing. I’m very happy I went with Atticare and my Rat issue is definitely resolved!
Atticare upgraded my insulation and cleaned my air ducts. The difference in air quality is noticeable. My allergies improved and the airflow around the house feels stronger. Five stars for their professionalism specially, to the technician, Sean.
