Get answers to common questions about insulation services in Severn, Maryland.
For most homes in Severn, blown-in cellulose or fiberglass in the attic is highly cost-effective, typically ranging from $1.50 to $3.50 per square foot installed, depending on depth and material. Spray foam offers superior air sealing for our humid Maryland climate but costs more ($2.00-$5.50 per board foot). Always get itemized quotes from local contractors, as material and labor costs in the Baltimore-Washington corridor can be higher than national averages.
Late spring (April-May) and early fall (September-October) are ideal. These periods offer mild temperatures, allowing contractors to work effectively in your attic without extreme heat, which is a safety concern in our humid summers. Scheduling during these shoulder seasons also ensures your home is prepared for both Maryland's cold winters and hot, sticky summers, and you'll avoid the busy season rush of contractors.
Yes, Severn follows the Maryland Building Performance Standards (MBPS), which are based on the International Energy Conservation Code (IECC). A reputable local installer will know the required R-values for our climate zone (Zone 4). Furthermore, check for available rebates through programs like the Maryland Energy Administration's Home Energy Loan Program (HELP) or federal tax credits for specific energy-efficient upgrades, which can significantly offset project costs.
Prioritize contractors who are licensed, insured, and have strong local references. Look for companies experienced with Maryland's specific climate challenges, such as managing attic moisture and providing proper ventilation to prevent mold. Verify they perform a pre-installation energy assessment and ask if they are a certified installer for the products they use. Checking reviews on local community pages or the BBB can also provide valuable insight.
Not entirely. While upgrading insulation (especially in the attic) is crucial, our humid climate means air sealing is equally important. Gaps, cracks, and poorly sealed ducts allow moist outdoor air to infiltrate, reducing comfort and efficiency. A comprehensive approach that combines air sealing with proper insulation and attic ventilation is the most effective solution for Maryland homes to combat both temperature swings and moisture issues.
