In Baltimore, proper insulation helps homes stay warm through cold winters and cool during humid summers. We install attic, wall, and basement insulation for older row homes and single-family houses. Most projects finish in 1-2 days. Free energy audits available. Our licensed insulation contractors help reduce energy bills and improve comfort.

Professional Insulation Installation Protects Baltimore Homes From Extreme Weather

Row home owners and older single-family houses lose heat through uninsulated walls and attics. We seal air leaks and add proper R-value in 1-2 days with minimal disruption to your daily routine. Baltimore’s brick row homes built before 1950 often have zero wall insulation. This makes retrofit insulation for existing homes critical for controlling winter heating bills. Our team handles the entire process from energy audit through final installation. You stay comfortable while we work.

The Right R-Value Keeps Baltimore Homes Comfortable and Energy-Efficient

Homeowners planning attic upgrades or whole-home energy improvements in neighborhoods like Hampden and Canton need the right R-value. Maryland code requires R-38 minimum for attics. We calculate exact needs based on your heating system and roof type. Baltimore’s cold winters demand higher attic R-values than southern Maryland coastal areas. Our contractors ensure your home meets code while maximizing energy savings. Proper R-value means lower bills and consistent temperatures in every room.

Signs Your Home Insulation Needs Replacement or Upgrading

Residents noticing uneven temperatures, high energy bills, or ice dams on older homes need insulation help. Our energy audits identify problem areas like compressed attic insulation or missing basement coverage. You get a clear report showing where your home loses energy. Humid Baltimore summers cause moisture damage in poorly ventilated attics. This reduces insulation performance over time. We check for water damage and ventilation issues before recommending upgrades. Catching problems early saves money on heating and cooling.

What is the best insulation for an attic in Baltimore, MD?

Spray foam and blown-in cellulose work best for Baltimore attics because they handle humidity and temperature swings. Both materials seal air leaks better than traditional fiberglass batts.
  • 1. Spray foam: Highest R-value per inch, blocks moisture
  • 2. Blown-in cellulose: Cost-effective, fills gaps around wiring
  • 3. Fiberglass batts: Budget option for newer construction
Maryland building code requires R-38 to R-60 in attics depending on your heating system.

Blown-In, Batt, and Spray Foam Insulation Methods Explained

Homeowners comparing options for attic upgrades, basement finishing, or crawl space sealing need to understand different methods. Each method suits different spaces. Spray foam works best for rim joists. Blown-in fills attics quickly and completely. Batts fit new construction walls. Baltimore row homes with shared walls benefit most from dense-pack cellulose in exterior walls. This material fills every gap without tearing down plaster. We help you choose the right method for your home’s age and layout.

Clients scheduled for installation in neighborhoods like Federal Hill and Bolton Hill need to prepare their homes. Clear attic access and move stored items before we arrive. We need power access for blowers and sprayers. Older Baltimore homes may need roof leak repairs or ventilation improvements before insulation work begins. Our team inspects your space during the energy audit. We tell you exactly what to do before installation day. Simple preparation means faster completion and better results.
