Trusted by Baltimore Homeowners
In Baltimore, attic insulation stops summer heat and winter cold from driving up your energy bills. We install attic insulation for homes across the city – new builds, older rowhomes, and single-family houses. Free inspections are available. Most jobs finish in one day. Our licensed insulation contractors in Baltimore handle Maryland code requirements and deliver measurable comfort improvements.
Maryland Attic Insulation Codes Set Minimum R-Values for Energy Efficiency
Maryland code requires R-38 attic insulation for energy efficiency. Homeowners upgrading old rowhomes or meeting code during renovations across Hampden and Federal Hill need to hit this minimum. You’ll lower heating and cooling costs immediately when your attic meets the R-38 standard.
Baltimore’s cold winters and humid summers demand proper R-values. Without enough insulation, ice dams form on your roof when warm air escapes through your attic. Condensation builds up during summer months. Both problems cost you money and damage your home.
We measure your current insulation depth during the free inspection. If you’re under R-38, we calculate how much material you need. Most Baltimore attics need 10-14 inches of blown-in insulation to reach code. Your energy bills drop the day we finish the install.

Attic Insulation Installation Follows a Clear Step-by-Step Process
Residents in Canton and Mount Vernon preparing for insulation upgrades in older homes follow a clear process. Professional crews handle air sealing, ventilation checks, and insulation install in one day for most attics. You get a complete upgrade without multiple visits or drawn-out timelines.
Baltimore rowhomes often share attic spaces. Proper air barriers prevent heat transfer between units. We seal the boundaries before adding insulation so your heating and cooling stay in your home.
Here's how we install attic insulation:
- 1. Inspect your attic for moisture, ventilation problems, and old insulation condition .
- 2. Seal air leaks around chimneys, vents, and electrical boxes.
- 3. Remove old insulation if damaged, wet, or contaminated .
- 4. Install baffles to keep roof vents clear
- 5. Check coverage depth and thermal performance .
- 6. Blow in or spray new insulation to meet Maryland R-value codes.
- 7. Clean the work area and restore attic access .
The crew arrives in the morning and finishes by late afternoon. You see lower energy bills within the first month.
Removing Old Attic Insulation Protects Air Quality and Performance
Homeowners in Fells Point finding water damage, mold, or pest contamination in existing insulation need full removal. Old insulation harbors allergens and moisture problems. New insulation performs better without old material blocking airflow.
High humidity near the harbor causes mold growth in damaged insulation. Removal stops health risks before we install new material. We bag and haul away all contaminated insulation so nothing harmful stays in your attic.
Water-damaged insulation loses its R-value. Mold spreads through fiberglass and cellulose when moisture sits too long. Rodent droppings and nesting materials create air quality problems throughout your home. We vacuum out the old insulation and sanitize the attic floor before adding fresh material.
You breathe cleaner air after removal. Your new insulation works at full capacity without contamination weighing it down.

Signs Your Baltimore Attic Needs Better Insulation Show Up Fast
Residents across the city noticing high energy bills or uneven room temperatures during extreme weather can spot the warning signs. Thin insulation, ice dams, or drafts mean you can fix comfort problems before next winter. Catching these issues early saves you money on heating and cooling.
Cold walls in Baltimore rowhomes often signal missing attic insulation between shared walls and roof lines. You’ll feel drafts near the ceiling during winter. Upstairs rooms stay hot all summer even with the AC running. Your furnace or heat pump runs constantly but rooms stay cold.
- Energy bills climbing every season
- Ice dams forming along your roof edge in winter
- Uneven temperatures between upstairs and downstairs rooms
- Visible gaps or thin spots in your current attic insulation
- Moisture or condensation in your attic space
We inspect your attic for free. You’ll know exactly how much insulation you need and what it costs before we start work.
ATTIC TYPES
Spray Foam and Blown-In Insulation Work Best in Different Attic Types
Homeowners in Locust Point and Roland Park choosing insulation types for unique attic shapes and access points need the right material. Blown-in cellulose works fast in open attics. Spray foam seals tight spaces and hard-to-reach areas.
Steep rooflines in older Baltimore homes make spray foam ideal for sealing gaps around dormers and eaves. The foam expands into cracks and creates an air barrier. Blown-in insulation settles into open floor spaces and covers large areas quickly.
Blown-in cellulose fits these situations:
- Open attic floors with easy access
- Large spaces that need fast coverage
- Budget-friendly projects that still meet R-38 codes
Spray foam works better for:
- Roof deck insulation when HVAC sits in your attic.
- Tight spaces around chimneys and ductwork.
- Sealing air leaks in hard-to-reach corners.
We recommend the best option during your free inspection. You get the right insulation type for your home’s layout and your budget.

FAQs
About Insulation & HVAC Services in
Baltimore
1. What R-value does attic insulation need in Baltimore?
Maryland code requires R-38 in attics for energy efficiency. This standard applies across Baltimore for new construction and major renovations. Your contractor measures insulation depth to confirm you meet the requirement.
2. How long does attic insulation last in Baltimore homes?
Fiberglass and cellulose last 20-30 years in Baltimore attics. Spray foam lasts 80+ years when installed correctly. Moisture damage or pest problems can shorten the lifespan of any insulation type.
3. Can I add new insulation over old in my Baltimore attic?
Yes, if old insulation is dry and undamaged. Wet or moldy insulation must come out first. We inspect your existing material during the free visit and tell you if removal is needed.
4. How do I know if my Baltimore rowhome attic is under-insulated?
Check for cold walls, ice dams, high energy bills, or visible gaps in existing insulation. Upstairs rooms that stay too hot or too cold also signal poor attic insulation. A free inspection confirms your current R-value.
5. Do Baltimore insulation contractors handle air sealing during install?
6. Should I insulate the attic floor or roof deck in Baltimore?
Insulate the attic floor for vented attics. Insulate the roof deck if your HVAC system sits in the attic. We inspect your setup and recommend the right approach during your free consultation.
