Hearn Insulation & Improvement in Baltimore: Full-Home Insulation and Retrofit Work

Hearn Insulation & Improvement is a licensed insulation contractor serving Baltimore with a focus on attic, wall, and basement insulation installation, plus weatherization upgrades for older homes. The company handles both new construction and retrofit projects, with particular strength in addressing the energy loss common to Baltimore's row house stock.

What Hearn Insulation & Improvement actually does

The business installs fiberglass batts, blown-in cellulose and fiberglass, and spray foam insulation. They also perform air sealing, duct sealing, and weatherstripping as part of comprehensive energy audits. Most of their Baltimore work centers on attic insulation (the fastest payback for homeowners) and basement rim joist sealing, jobs that address where older rowhouses leak heat most visibly. They are licensed by the Maryland Department of Labor and carry liability insurance.

Services and pricing

Attic blown-in insulation in Baltimore typically runs $1.50 to $3 per square foot, depending on desired R-value and material (cellulose costs less than fiberglass). A 1,000-square-foot attic brought to R-38 (Maryland code baseline) usually costs $1,500 to $2,500 before any rebates. Basement rim joist spray foam sealing runs $8 to $12 per linear foot; a rowhouse perimeter of 120 linear feet might total $960 to $1,440. Wall cavity insulation (for new construction or during renovation) runs higher due to labor, typically $3 to $5 per square foot of wall area. Air sealing packages start at $500 for targeted work around windows and doors. Verify current pricing by phone; energy costs and material supply affect rates seasonally.

Hearn offers free in-home estimates. They can coordinate with Baltimore utility rebate programs (BGE offers insulation rebates up to $500 for qualifying jobs), and staff can walk through rebate eligibility during the estimate.

How Hearn compares to other Baltimore insulation contractors

Baltimore has several insulation specialists. Comfort Systems and Energy Efficiency First both operate locally and offer similar retrofit packages, though both typically market more heavily to HVAC customers and may bundle insulation as an add-on rather than a primary service. Hearn positions insulation as its core business. For spray foam work specifically, some homeowners also hire roofing companies that have added spray foam services; these firms may prioritize attic access during roof replacement over standalone retrofit jobs. Hearn accepts insulation-only calls year-round. Choose Hearn if insulation retrofit is your goal and you want a contractor whose primary expertise is thermal envelope work. Choose a bundled HVAC contractor if you need both furnace replacement and insulation in one project and value coordinated scheduling.

Who it suits and who it does not suit

Hearn serves homeowners in older Baltimore neighborhoods (Canton, Fells Point, Federal Hill, Hampden) where attic and basement insulation gains are high and payback is fast. They also work on newer construction during framing phase. It suits owners planning to stay in place and recoup energy savings, or sellers preparing for inspection. It does not suit renters (landlord decision) or anyone unwilling to have attic access opened or drywall disturbed for wall cavity work. Spray foam projects require the home to be vacant for 24 hours post-application; scheduled timing matters.

What the first visit involves

The estimate appointment includes a walkthrough of attic, basement, and exterior. The estimator checks current insulation levels with an infrared thermometer or visual inspection, identifies air leaks (often visible around recessed lights, exhaust vents, and rim joists), and discusses R-value targets. They review material options (cellulose, fiberglass, foam) and explain the difference in performance and cost. The estimate is written onsite or emailed the next day. Most jobs are scheduled within two to four weeks. Installation typically takes one to three days depending on scope; blown-in attic work can happen in a single day.

Hours, parking, and logistics

Hearn operates Monday through Friday, 8 a.m. to 5 p.m. (verify for weekend availability). Estimates are booked by phone or online form. Work is scheduled during daylight hours. For Baltimore rowhouses, contractor parking is street-parking; let Hearn know if on-street spots are tight on your block. Equipment trucks are full-size; narrow alleys in some neighborhoods may require parking a block away. Material delivery happens the day of or the day before installation.

Hearn Insulation & Improvement handles the kind of foundational work that compounds over time in a city where heating and cooling costs are substantial and homes are often decades old. It earns its spot by focusing expertise where it matters most for Baltimore rowhouses.
