I specialize in residential insulation and air sealing to reduce drafts, cold spots, and high heating costs — which often leads to fewer tenant complaints and lower utility costs.

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation FAQs, answered by experts

The best time to insulate a garage ceiling is when the weather is mild and dry. That means it shouldn’t be stormy, snowy, or raining, and the temperatures should be comfortable. Ideally, you’ll insulate your garage ceiling in the fall, before winter hits. Not only will you be the most comfortable, but you’ll also likely see the greatest energy savings heading into the colder weather with a newly insulated garage.

Chimney liners often benefit from insulation, though it is not always required. Insulation helps improve the liner's efficiency by keeping flue gasses hotter, which enhances draft and reduces creosote buildup. It also prevents condensation, which can lead to corrosion. Insulation is important for chimneys on exterior walls or in colder climates. Some building codes may require insulation, so checking local regulations is essential.

One of the disadvantages of soffit vents is they can bleed warm air from the attic during winter, resulting in slightly higher energy bills and a colder house. There are ways to mitigate this effect—mostly just closing the vent in the fall. What’s most important is your attic is ventilated to some degree in the winter.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

The benefits of insulating your pipes include preventing freezing, sweating, and condensation. In addition, insulating your pipes can make your home more energy-efficient by keeping your pipes from losing or gaining heat. You’ll be able to turn the temperature of your water heater down by two to four degrees Fahrenheit. According to the U.S. Department of Energy, this can reduce energy costs by 3% to 4% per year.
