Most homeowners think about siding primarily in terms of curb appeal or storm protection. But quality siding installation is also one of the most impactful energy efficiency upgrades you can make to a home in the Annapolis area — a benefit that is often undersold.
Maryland’s climate swings hard in both directions: brutal summer humidity and heat that pushes air conditioning systems to their limits, followed by cold, damp winters that stress heating systems just as aggressively. Old or damaged siding is a significant contributor to energy loss in both seasons.
How Old or Damaged Siding Drives Up Energy Costs
Siding is part of your home’s thermal envelope — the continuous barrier between conditioned interior space and the outdoor environment. When that envelope has gaps or compromised sections, conditioned air escapes and outdoor air infiltrates. In Annapolis summers, that means hot, humid Bay air pushing into your home and forcing your AC to work harder.
· Gaps at seams and joints where panels have shifted or separated
· Cracked or missing caulking around windows, doors, and exterior penetrations
· Physical damage from storms that has opened gaps in the siding surface
· General aging and degradation that reduces insulating properties
What Insulated Vinyl Siding Adds
CertainTeed vinyl siding, which we install throughout Anne Arundel County, is available with a continuous insulation backing that provides a meaningful R-value improvement over standard siding. This is most pronounced in homes with older wall assemblies — which describes a significant portion of the housing stock in Annapolis, Severna Park, and the rest of the county, where many homes were built in the 1960s, 70s, and 80s and weren’t constructed to modern energy standards.
Beyond Insulation: The Air Sealing Benefit
One of the most significant energy efficiency benefits of a new siding installation comes from the process itself: a full installation involves removing the old material, inspecting and addressing any damage to the wall sheathing underneath, and properly sealing every penetration before the new siding goes on. This is essentially an air sealing project on the exterior of your home.
