Get answers to common questions about insulation services in Dundalk, Maryland.
For Dundalk's humid subtropical climate with cold winters and hot, humid summers, a balanced approach is key. We highly recommend air sealing and attic insulation (typically blown-in cellulose or fiberglass to at least R-49) as a top priority to combat both summer heat gain and winter heat loss. For older homes, adding wall insulation (often via dense-pack cellulose injection) and properly insulating basements or crawl spaces is crucial to manage moisture and improve year-round comfort.
Costs vary significantly based on home size, insulation type, and areas serviced, but local projects often range from $1,500 to $4,500 for a standard attic insulation upgrade. Whole-home projects involving walls and crawl spaces can reach $8,000+. It's important to get multiple quotes, as regional material and labor costs apply. Many Maryland homeowners qualify for rebates through programs like the BGE Home Energy Savings Program or federal tax credits, which can offset 30% of the cost up to $1,200.
While insulation can be installed year-round, the ideal times are late spring (April-May) and early fall (September-October). These periods typically offer milder weather, making it easier for contractors to perform critical air sealing work and for you to have your attic accessed safely. Scheduling during these shoulder seasons also ensures your home is prepared for the peak heating and cooling demands of Dundalk's summer and winter.
Always verify the contractor is licensed and insured in Maryland. Look for companies with specific experience in older Dundalk homes, which may have knob-and-tube wiring or plaster walls requiring special techniques. Ask for local references and check reviews. A reputable provider should perform a thorough energy audit or assessment first and clearly explain their recommended R-values, air sealing methods, and compliance with Maryland's building codes.
Absolutely, but it must be done correctly. In our coastal climate, a drafty home often suffers from significant air leakage, which allows humid summer air inside, leading to condensation and mold risk. The solution is a comprehensive approach: professional air sealing of gaps, cracks, and bypasses first, followed by adding the correct type and amount of insulation. This controls moisture migration, improves indoor air quality, and enhances comfort more than insulation alone.
