Trusted by Baltimore Homeowners
In Baltimore, drafty windows and doors drive up heating bills during harsh winters. This page covers draft sealing for windows, doors, baseboards, and gaps that let cold air inside. You’ll learn where drafts hide, how sealing works, and what Baltimore homeowners should expect. Most homes get sealed in 2-4 hours. We provide this service year-round through licensed insulation contractors serving Baltimore, MD who understand mid-Atlantic weather demands.
Window and Door Gaps Let Cold Air Into Baltimore Rowhomes and Split-Levels
Cold spots near windows or doors mean air leaks through gaps you can’t always see. We seal these openings to stop icy drafts that make rooms uncomfortable even when your heat runs. Baltimore rowhomes often share walls but have exposed front and back doors. Gaps form around jambs and thresholds where cold air pushes inside. Our contractor inspects every window sash, door frame, and threshold during your appointment. We apply caulk or foam where air moves through. This keeps your heated air inside where it belongs.

Caulk and Weatherstripping Block Different Types of Drafts
Foam tape from hardware stores often fails because it doesn’t match the leak type. Caulk seals cracks that do not move. Weatherstripping handles parts that open and close. Freeze-thaw cycles crack old caulk around brick window frames common in mid-Atlantic construction. We use flexible caulk on stationary joints like where window frames meet brick. Adhesive-backed weatherstripping goes on door edges and window sashes. Each material does a different job. Using the right one in the right place stops cold air for good.
Baseboard Gaps Create Floor-Level Drafts in Older Baltimore Neighborhoods
Cold ankles near baseboards mean air leaks behind your trim. Settling foundations and old horsehair plaster leave voids behind baseboards in century-old Baltimore rowhouses. These hidden gaps pull cold air from wall cavities into your rooms. We remove trim if needed to reach the void. Low-expansion foam fills the gap without pushing trim out of place. We re-secure the baseboard and caulk the top seam where it meets your wall. Floor-level drafts disappear after we seal these hidden leaks. For comprehensive protection throughout your home, our air sealing services in Baltimore address all major leak points.
Sealed Windows and Doors Lower Heating Costs All Winter
High winter gas bills happen when heated air escapes through unsealed cracks. Draft sealing keeps that air inside so your furnace runs less often. January lows near 25°F mean every unsealed crack forces your heating system to work overtime. The average Baltimore home sees a 10-15% heating cost drop after we seal all window and door perimeter gaps. Your rooms feel warmer and your bills go down. The savings continue every winter after we finish the work.
How Draft Sealing Works in Baltimore Homes
Draft sealing closes gaps around windows, doors, and baseboards where air leaks occur. In Baltimore’s freeze-thaw climate, these gaps let cold air inside and push heated air out. We use three methods to stop the leaks:
- Caulk fills stationary cracks in frames and trim
- Weatherstripping seals movable parts like door sweeps
- Spray foam closes hidden gaps behind baseboards
The result is warmer rooms, lower gas or oil bills, and less noise from outside.

Removing Old Caulk Prepares Surfaces for Long-Lasting Seals
New caulk won’t stick to old, cracked material. UV exposure and humidity degrade old caulk around south-facing windows in Fells Point and Harbor East condos. We scrape or cut away the old bead first. Solvent cleans any residue left behind. The surface dries completely before we apply fresh caulk. This preparation ensures the new sealant bonds tightly. Properly prepped surfaces let caulk last years instead of months. For detailed guidance on sealing window and door trim, ENERGY STAR provides comprehensive DIY instructions.

Painted Caulk Blends Seamlessly After Draft Sealing Work
Sealed gaps should disappear into your trim color. Paintable caulk accepts latex or oil paint so sealed joints match your existing woodwork. Historic districts like Bolton Hill require exterior work to match original appearance. Paintable sealant preserves your curb appeal while stopping drafts. We apply paintable acrylic latex caulk and smooth the bead. The material needs 2-4 hours to dry before priming and painting. We match your trim color so the sealed joints blend in completely.

FAQs
About Insulation & HVAC Services in
Baltimore
1. Does draft sealing work in Baltimore rowhomes with shared walls?
Yes, sealing front and back doors and exposed windows stops most air leaks even when side walls connect to neighbors. Rowhomes lose heat through the openings you control. We focus on those areas to cut drafts and lower your heating costs.
2. How long does caulk last around windows in Baltimore weather?
Quality exterior caulk lasts 5-10 years in Baltimore. Freeze-thaw cycles and sun exposure determine the actual lifespan. South-facing windows may need re-caulking sooner than north-facing ones. We use products rated for mid-Atlantic weather conditions.
3. Can I seal drafts myself or should I hire an insulation contractor in Baltimore?
Small jobs work for DIY if you have the right materials. Whole-home sealing benefits from professional insulation contractors in Baltimore who use tools like infrared cameras to find hidden leaks. We locate drafts you can’t feel or see. Our equipment and experience deliver complete results the first time.
4. When is the best time to seal drafts in a Baltimore home?
Fall months from September through November work best before the heating season starts. We also work year-round when temperatures stay above 40°F for caulk to cure. Scheduling before cold weather arrives gives you immediate savings on heating bills.
5. Will draft sealing stop all cold air from coming through my Baltimore windows?
Sealing stops air leaks around frames where gaps let wind inside. Single-pane glass still conducts cold through the material itself. Drafts from gaps disappear completely after we seal them. You’ll feel the difference right away on windy days.
6. Do I need to remove old weatherstripping before adding new material?
Yes, peeling or compressed weatherstripping should come off first. Fresh strips need clean surfaces to compress evenly and seal tightly. We remove old material and clean the channel before installing new weatherstripping. This ensures a proper seal that lasts.
