Air leaks in Baltimore homes make heating and cooling bills go up all year. This page shows how air sealing works and what happens during service. We help folks in rowhouses, single-family homes, and older homes across Charm City. Call Home Energy Pros for a free look at your home. We’ll make a plan to seal your home and stop energy waste.
Air Sealing Targets the Hidden Gaps That Waste Energy in Your Home
Homeowners in Hampden and Canton feel drafts or notice some rooms are hotter or colder than others. Air sealing closes tiny cracks around pipes, wires, and ducts. These cracks let heated or cooled air escape. Baltimore rowhouses share walls with neighbors. Air usually leaks through top-floor ceilings and basement rim joists instead of outside walls.
When you heat or cool your rowhouse or home, air sneaks out through every gap. Small holes around pipes and electrical boxes add up fast. We find these hidden leaks and seal them. Your home keeps its temperature better. Your heating and cooling system doesn’t work as hard fighting the Harbor humidity or winter cold off the Chesapeake. For complete help, our draft sealing services fix air leaks and make your home more comfortable.

Professional Air Sealing Cuts Heating and Cooling Costs by 15-30%
Residents in Federal Hill and Fells Point want lower bills without buying new heating or cooling systems. Sealed homes keep heat in during winter and cool air in during summer. Your furnace and AC don’t run as much. Baltimore gets hot, sticky summers and cold winters that blow in from the Bay. Leaks make your heating and cooling work extra hard all year.
When air escapes through gaps, your equipment turns on and off more often. This wastes energy and makes your monthly bills higher. Air sealing stops that loss. You keep more heated or cooled air inside. Your systems reach the right temperature faster using less gas or electricity. BGE customers can get rebates averaging $3,000 for home performance improvements like air sealing through the EmPOWER Maryland program.
The crew arrives in the morning and finishes by late afternoon. You see lower energy bills within the first month.
Older Baltimore Homes Get the Most Value from Air Sealing
Owners of rowhomes built before 1950 in Bolton Hill and Charles Village have high energy bills and drafts. Old Baltimore homes were built before energy rules existed. Air sealing makes the biggest difference in these homes. Many rowhouses around the city have balloon framing and no insulation in the walls. This makes attic and basement sealing very important.
These older Baltimore homes have features that let air move easily. Balloon framing lets air travel from the basement to the attic inside the walls. Gaps around floor joists and at the top let air move freely. When we seal these paths, you feel better right away. Cold spots go away. Your heating bills go down.

Attics, Basements, and Rim Joists Need Air Sealing First
Homeowners in Locust Point and Pigtown have cold floors in winter or hot upstairs rooms in summer. These areas have the biggest leaks. Sealing them saves you money fastest. Baltimore basements often have no finished walls. This makes rim joists and sill plates easy to reach and seal quickly.
Your attic is where most heat escapes in winter. Warm air goes up and finds every hole in the ceiling. In the basement, rim joists sit where the foundation meets the floor framing. They create a long air gap. We work on these big problem areas first. You feel more comfortable right away and get the best value.
ATTIC TYPES
Air Sealing Uses Spray Foam, Caulk, and Weatherstripping to Block Leaks
Folks across Baltimore want to know what materials an insulation contractor uses during service. Each material fixes a different type of leak. Some fix large gaps. Others fix tiny cracks. Spray foam works best in Baltimore attics around ceiling lights and pipes that go through the ceiling.
We use two-part spray foam for gaps bigger than a quarter. Caulk seals smaller cracks around window frames and electrical boxes. Weatherstripping goes on doors and attic hatches. The right material depends on how big the gap is and where it sits. Our crew looks at each leak during service and uses the right fix.

How is air sealing done in Baltimore?
An inspector uses a blower door test to find leaks. A worker seals attic holes with spray foam. The crew puts caulk around the window and door frames. The team insulates rim joists in the basement. A worker adds weatherstripping to outside doors. A final test shows air leakage has dropped. You get a report with before and after numbers.

FAQs
About Insulation & HVAC Services in
Baltimore
1. How long does air sealing take in a Baltimore home?
Most homes take 4-8 hours based on size and number of leaks. Smaller rowhouses with easy-to-reach attics and basements often finish in half a day. Bigger single-family homes with many floors may need a full day.
2. Can air sealing help with my high gas bill in winter?
Yes, sealing stops heat loss so your furnace runs less often. When warm air stays inside, your heating system gets to the right temperature faster. It turns on less. Many Baltimore homeowners see lower bills in the first heating season.
3. Do I need air sealing if I already have insulation?
Yes, insulation slows heat moving through walls but air sealing stops air from moving through gaps. Insulation only works when air isn’t flowing around it. Sealing gaps first makes your insulation work better.
4. Will air sealing reduce humidity in my Baltimore basement?
It helps by blocking outside air, but you may still need a dehumidifier in summer. Air sealing reduces moisture coming in through rim joists and foundation gaps. High Baltimore humidity in summer often needs both sealing and a dehumidifier.
5. What neighborhoods in Baltimore see the biggest savings from air sealing?
Older neighborhoods like Hampden, Canton, and Federal Hill with rowhomes built before 1950. These homes have the most air leaks and use the most energy. Air sealing makes a big difference in comfort and cost.
6. Should I seal my attic or basement first?
Attic sealing usually gives faster results because heat rises and escapes through the top floor. If you can only do one area now, start with the attic. You’ll feel warmer in winter and cooler upstairs in summer right away.
