Why DeWitt Homes Need Upgraded Insulation

DeWitt sees cold, snowy winters and warm, humid summers—classic Central New York weather that pushes your HVAC system to the limit. Unfortunately, many homes in the area were built before modern energy codes, and even newer homes are often under-insulated or poorly sealed.


If you’ve experienced any of the following, your home may be due for an insulation upgrade:


  • Drafts around baseboards, outlets, or attic access
  • Cold floors and inconsistent temperatures
  • High energy bills all year
  • Ice dams forming on the roof
  • Moisture or mildew in the basement

HAPPY CUSTOMER IN DeWitt, 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!

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 Insulation Services in DeWitt, NY

We provide full-service insulation solutions customized for the age, layout, and goals of your home or building.

Great for attic floors and open wall cavities, blown-in cellulose is made from recycled materials and offers excellent air sealing and fire resistance. It’s a top choice for improving R-values in attics.

Ideal for retrofitting insulation into finished walls—especially in DeWitt’s older homes—without removing drywall. We tightly pack cellulose into each cavity for long-lasting thermal performance and draft control.

We install batt and loose-fill fiberglass in attics, basements, and crawl spaces. When combined with air sealing, it offers dependable comfort and is budget-friendly.

This often-forgotten area at the top of your foundation wall is a major source of heat loss and moisture. We use spray foam or rigid foam board to seal and insulate rim joists, preventing drafts and mold issues.

We use blower door tests and thermal imaging to identify hidden air leaks around doors, windows, ductwork, and framing. We then seal these areas with caulk, foam, and gaskets—improving the overall effectiveness of your insulation.

Since 2019, homeowners in DeWitt have seen a 54% increase in utility costs, with continued increases expected. Heating and cooling account for the majority of energy usage in a typical home—and without proper insulation, much of that energy goes to waste.

FAQs in DeWitt, NY

  • My DeWitt home is older—can you add insulation without damaging the walls?

    Yes! We use dense-packed cellulose, which can be installed through small holes drilled between wall studs. We patch these holes afterward, leaving minimal impact.

  • Does attic insulation help in the summer too?

    Absolutely. Insulation slows down heat transfer, keeping hot attic air from penetrating your living space during warm months.

  • Can you help prevent ice dams on my roof?

    Yes. Ice dams are caused by poor attic insulation and air leaks. We seal and insulate attics to help maintain a consistent roof temperature and prevent melting snow from refreezing at the eaves.

  • What insulation upgrades make the biggest impact?

    Air sealing, attic insulation, and rim joist insulation provide the most immediate and cost-effective improvements in most homes.

  • Are there rebates for insulation upgrades in DeWitt?

    Yes! Many homeowners qualify for federal tax credits, NYSERDA rebates, and utility company incentives. We’ll help you navigate the paperwork to maximize your savings.
