Why Insulation Is Essential in Manlius, NY

The Manlius area experiences all four seasons in full force: frigid, snowy winters and humid, hot summers. That weather takes a toll on heating and cooling systems, especially in older or under-insulated homes. If your home lacks proper insulation or air sealing, you’re likely dealing with:


  • Cold rooms and uneven heating
  • Soaring energy bills in winter and summer
  • Ice dams forming along the roofline
  • Drafts around windows, floors, or baseboards
  • Moisture buildup in crawlspaces or basements



Our goal is to help you take back control of your comfort and energy usage—with custom insulation solutions that work.

HAPPY CUSTOMER IN  Manlius, NY

Matthew and his team did an excellent job insulating my garage at a very competitive price. The crew was not only friendly but also highly efficient, completing the job on time and with great attention to detail. They were able to schedule the work much sooner than other local companies I contacted, which was a big plus. I’ve already noticed a significant improvement in how well the garage retains heat, and I couldn’t be happier with the results. I highly recommend Matthew and his team for any insulation work – they truly exceeded my expectations!

Heather S.

We had blown in insulation added to our attic in our modular ranch.. Matt provided a fair bid and also was onsite during the installation. Our job was not simple but Matt and JD completed it per the the time estimate and price. We are very satisfied with experience.

Matthew responded quickly and got us on his schedule as soon as possible. He provided an extremely reasonable estimate and went over the entire process ahead of time. He showed up right on time and he and his crew finished the job in less than 2 hours. He and was very friendly and professional throughout the whole process. Our garage is now very well insulated; no more giant icicles threatening to destroy our gutters or giant ice dams threatening to damage our roof! Highly recommend!

Our Insulation Services in Manlius, NY

We provide complete insulation upgrades and air sealing services for residential and light commercial properties in Manlius.

An ideal option for attics and open wall cavities, blown-in cellulose is eco-friendly, fire-resistant, and effective at stopping air leaks and maintaining indoor temperatures.

For older homes in Manlius, we retrofit insulation into finished walls using dense-packed cellulose. This method fills every cavity without removing drywall and creates a strong air-sealing layer.

We install fiberglass batts and loose-fill insulation in attics, floors, and crawl spaces. It’s affordable and effective—especially when paired with our air sealing services.

The rim joist is a key area where air, moisture, and cold enter your home. We seal and insulate it with spray foam or foam board to improve comfort and prevent mold in basements.

Air sealing is often overlooked, but it’s critical. We use blower door testing and thermal imaging to detect air leaks throughout your home and seal them with professional-grade materials for lasting energy savings.

The True Cost of Poor Insulation: Energy Prices Are Climbing

FAQs in Manlius, NY

  • What type of insulation is best for older Manlius homes?

    Dense-packed cellulose is often ideal for older homes, as it can be installed without removing walls and provides excellent air sealing and thermal performance.

  • Will insulation help prevent ice dams?

    Yes. Proper attic insulation and air sealing prevent warm air from melting snow on the roof, which leads to ice dam formation.

  • How do I know if my insulation is up to code?

    Most homes built before 2000 in Manlius are under-insulated by today’s standards. We can assess your insulation and recommend upgrades to meet current energy codes.

  • Can insulation help with summer comfort?

    Absolutely. Insulation keeps heat out in the summer and in during the winter—helping maintain even, comfortable indoor temperatures year-round.

  • Are rebates or tax credits available for insulation upgrades in Manlius?

    Yes! We’ll help you explore NYSERDA rebates, National Grid incentives, and federal tax credits to maximize your savings.
