"My consultation with Stellar was scheduled within a day, met with Patrick on 5/1/25. Time was taken to understand the process, everything that is involved and what my options were. Time was taken to listen to what we wanted/didn’t want and thorough explanation given of the entire process. On 5/2/25 Stellar contracting called to review details and confirm our choices. On 5/5/25 Stellar scheduling called and full installation scheduled for 5/9/25, completed 1 day! The crew and project manager, Cisco, were fabulous to deal with on the install day and even after. A link was provided where we could see pictures of the whole project as it happened. Cisco was readily available on install day and even after with questions and concerns. It was obvious that Cisco did care about the roof we were getting and took pride in the quality of the job that was done. The crew paid good attention to the clean up, there was a lot of debris all over the place. Looking forward to future business with them!"

Little Wolf Wildlife Control LLC is a Pest Control business that specializes in rodent removal and preventative methods. Our team consists of experienced wildlife professionals that work under a Nuisance Wildlife Control Operator license issued directly from the DEC. With that knowledge and over 10 years of experience in the field, Little Wolf Wildlife Control is able to locate exactly how animals are entering your home, and come up with cost effective solutions for removing the animals and preventing them from re-entering.

"I hired this company last October to illuminate mice and squirrels in my basement. In the beginning I thought highly of John and Anthony and thought they corrected the problem but in January the squirrels were back. I called them and their phone number says that the voicemail is full. I wrote to them and asked them to call me. They never contacted me and still haven’t. I keep trying to contact them, but they refused to accept my calls. John told me I would have a guarantee to get rid of them for one year which did not happen. I am totally frustrated that they won’t even have the courtesy to call me back. I would not recommend them at all."

"I just had my house raised almost 3 feet because of past flooding along Lake Ontario. I hired Josh (AB Capital) to foam underneath the house and add insulation in my attic. The morning Josh and his wife Stephanie arrived, my pipes were frozen. They created a temporary barrier for me, set up a propane heater to blast warm air in the temporary enclosure, and thawed my pipes so I would have water. We rescheduled the insulation installation for the next morning, but again, my pipes froze overnight, so he set up something more sophisticated and my pipes quickly thawed. He and Stephanie then went to work in freezing temperatures to do the job I hired them to do, and I couldn't be happier. Last night, my floor was warm, my furnace was able to cycle on and off normally, and my second floor temperature was finally comfortable (not too hot), AND I had water in the morning. I'm so happy they did this job. Josh is incredibly knowledgeable, professional, and quick responding. What a great company!"

Insulation questions, answered by experts

When it comes to fiberglass insulation versus foam board, there are a few notable differences, both aesthetically and functionally. Fiberglass insulation is soft and flexible, meaning it can be squeezed into tight spaces more easily than foam board. Fiberglass insulation also has a higher R-value, making it a better pick for colder climates. However, foam board insulation can resist moisture and pest damage much better than fiberglass.

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

Yes, cold walls could indicate that your home has poor insulation, especially if the walls are significantly colder than the air or other areas in the home. In most cases, cold walls are a sign that the heat produced by your furnace isn’t hanging around long enough to make the walls warm. If that’s the case, hire a local HVAC technician to take a closer look at your heating system.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

A dehumidifier can reduce condensation on your ductwork by lowering humidity levels in the air. Condensation occurs when humid, warm air makes contact with cold ducts. A dehumidifier can help maintain your home's indoor humidity below or around 50%, minimizing moisture buildup. However, if condensation is caused by leaks, cracks, or other damage, a dehumidifier won’t solve the problem.
