Get answers to common questions about insulation services in Marriottsville, Maryland.
For our humid summers and cold winters, air sealing combined with adding attic insulation (typically blown-in cellulose or fiberglass to R-49) offers the best return on investment. This directly combats energy loss through the roof, a major issue in Maryland's variable climate. Many local providers also recommend insulating basement rim joists, as this is a common source of drafts and moisture issues in our region's older homes.
The ideal times are late spring (April-May) and early fall (September-October). These periods typically offer mild, dry weather, which is crucial for proper installation of materials like spray foam and for effective air sealing. Scheduling during these shoulder seasons also avoids the peak summer and winter demand, potentially leading to better availability and pricing from local contractors.
Yes, insulation work must comply with the 2021 International Energy Conservation Code (IECC) as adopted by Maryland and enforced by Howard County. More importantly, Maryland homeowners, including those in Marriottsville, have access to excellent rebates and financing through programs like the Home Energy Loan Program (HELP) and EmPOWER Maryland, which can significantly offset the cost of qualifying energy efficiency upgrades.
Prioritize contractors licensed and insured in Maryland with specific experience in our climate zone. Ask for local references in Howard County and verify they perform a pre-installation energy audit or assessment. A reputable provider will be knowledgeable about both state rebates and the specific challenges of insulating homes in our area, such as managing humidity and dealing with older construction styles.
Absolutely. Drafts and inconsistent temperatures are classic signs of poor insulation and air leakage, which are common in homes not updated for Maryland's climate. The temperature swings in Marriottsville put extra strain on your HVAC system if your building envelope is weak. A professional energy assessment can pinpoint if the issue is primarily in the attic, walls, or basement, and identify air leaks that need sealing alongside adding insulation.
