"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."

At country side I will preform diagnostics tests on where air is leaking. Attics outside walls and basement are all areas that can be treated. Thinking your a.c is not cold enough? Your home might not be air sealed which is standard package. Worked for the best company in Rochester and was trained on site up to running own crew. Everything is free estimate with pictures.

We will strive to exceed the expectations of our customers while conserving resources and preserving the quality of the environment and our products. If you want to create a thermally efficient and air tight space, it's not enough just to insulate. You must choose the right installer!

"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

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.

The life span of insulation is between 20 and 100 years. At that time, existing insulation can fall victim to gravity, resulting in compression, which reduces its insulating protection or R-value. If you can't simply add more insulation over the existing material, removing the old to increase the effectiveness of the new can reduce your energy bills and make the project worth the time and money investment.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

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.

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.
