Stop Winter Drafts: Fort Washington Air‑Sealing Checklist

Do you feel a chill near doors, outlets, or the attic hatch as soon as the wind picks up? In Fort Washington winters, those tiny gaps can add up to bigger bills and rooms that never feel cozy. You want a warm, efficient home that is comfortable all season and appealing when it is time to sell. This guide gives you a clear, local checklist to stop drafts, where to start, what it costs, and how to tap PECO rebates and federal credits. Let’s dive in.

Why air sealing matters in Fort Washington

Fort Washington sits in a mixed‑humid climate with meaningful winter heating needs. In this region, tightening your home’s envelope pays off. According to federal guidance, pairing insulation with strategic air sealing can deliver solid winter savings in Climate Zone 5 homes. You can review the DOE overview of insulation and sealing best practices and qualifying upgrades from the U.S. Department of Energy.

ENERGY STAR modeling shows typical whole‑house savings around 11 to 15 percent when you combine air sealing with insulation, with higher potential in leakier or older homes. See the national methodology for expected savings by climate zone from ENERGY STAR.

Start with a quick diagnosis

Before you buy materials, identify the biggest leaks.

• Do a DIY walk‑through. On a cold day, feel for drafts around doors, baseboards, attic hatches, and outlets on exterior walls. Look for daylight at thresholds and gaps around pipes or cables.
• Book a professional assessment. A blower‑door test pinpoints leaks and verifies results after the work. PECO offers discounted assessments and access to participating weatherization contractors. Learn how to schedule a visit on the PECO program page.
• Use a simple plan. Inspect, audit, seal the worst leaks, add insulation where needed, then verify. For a DIY assessment checklist, see the DOE Energy Saver guide.

Follow this priority order for the best comfort and value.

Highest‑priority leaks to seal

• Attic floor and penetrations. Seal gaps at top plates, plumbing vents, recessed lights, chimney chases, and the attic hatch. Use caulk for hairline cracks, low‑expansion foam for 1/4 to 2 inch gaps, and rigid or spray foam for larger openings. After sealing, add or top off attic insulation for the biggest combined savings. See DOE guidance on effective sealing and insulation here.
• Rim joist or band joist. At the foundation, seal and insulate the rim joist to stop cold air at its source.
• Major service penetrations. Seal around dryer vents, plumbing stacks, electrical and cable lines, and HVAC penetrations into unconditioned spaces. Use foam, gaskets, or fire‑rated sealant where required. A basic how‑to overview is available in the DOE DIY assessment guide.

Medium‑priority comfort boosts

• Ductwork in unconditioned spaces. Seal joints with mastic or UL‑rated foil tape, then insulate accessible runs. Leaky ducts dump heat into attics or basements you do not occupy.
• Attic hatch or pull‑down stairs. Add a gasket and an insulated cover to cut a common, high‑impact leak.
• Recessed lights beneath the attic. Replace with airtight IC‑rated housings or seal from the attic side using approved methods.

Lower‑cost, DIY wins

• Weatherstrip exterior doors, adjust thresholds, and add door sweeps. Caulk gaps at interior trim where needed.
• Add foam gaskets behind outlet and switch plates on exterior walls.

Contractor‑level projects

• Wall cavity sealing or dense‑pack insulation during siding work or renovation. Most cost effective when bundled with larger projects.
• Fireplaces and chimneys. Check dampers, consider top‑sealing dampers, and use a qualified pro for any chimney work.

Materials guide at a glance

• Caulk for narrow cracks under 1/4 inch around trim and baseboards.
• Low‑expansion canned spray foam for 1/4 to 2 inch gaps around pipes and penetrations.
• Closed‑cell spray foam or rigid foam plus sealant for large, irregular openings and rim joists.
• Weatherstripping and door sweeps for operable doors and windows.

Safety first

Tightening a home changes how air moves. If you have gas, oil, or propane appliances, perform combustion safety testing before and after major air‑sealing work. Never block required vents or exhausts. A certified energy auditor will include these checks as part of a comprehensive audit. For a safe DIY assessment checklist, review the DOE Energy Saver guidance.

What it costs

• Energy audit with blower‑door. Typical pricing runs about 200 to 700 dollars, with many utilities offering discounts. PECO’s assessment options and participating contractors can reduce out‑of‑pocket costs. National pricing ranges are outlined by HomeAdvisor.
• Common project ranges. DIY caulking and weatherstripping often come in under a few hundred dollars. Rim‑joist sealing can range from a few hundred dollars to about a thousand depending on access. Attic sealing plus insulation often falls in the low thousands, depending on size and depth. Duct sealing typically ranges from several hundred to a couple thousand dollars.

Savings and payback

In mixed‑humid climates like ours, combining air sealing with insulation commonly delivers low double‑digit energy savings. ENERGY STAR’s national modeling estimates about 11 to 15 percent on average, with faster payback for lower‑cost items like weatherstripping and caulk. Actual results vary by home size, heating fuel, and pre‑retrofit leakage.

Local rebates, credits, and permits

PECO programs

PECO offers discounted energy assessments and access to participating contractors who can apply available incentives to qualifying weatherization work. Start here on the PECO program page.

Pennsylvania Weatherization Assistance

Income‑eligible households can receive no‑cost air sealing, insulation, and heating repairs through the state’s Weatherization Assistance Program. See eligibility and how to apply on the Pennsylvania DCED WAP page.

Montgomery County resources

When available, the Whole Home Repairs Program provides grants for eligible homeowners that can include energy‑related repairs. Check current status on the Montgomery County program page.

Federal tax credits

The Energy Efficient Home Improvement Credit provides a 30 percent federal tax credit for qualifying air‑sealing and insulation materials and installation, subject to annual caps. Home energy audits may also qualify for a limited credit. Review current rules on the IRS credit page. Keep invoices and audit documentation for filing.

Permits in Upper Dublin Township

Typical caulking, weatherstripping, and air‑sealing repairs do not require a permit. Larger projects, like major insulation during a remodel or work that touches mechanical, electrical, or plumbing systems, may require permits and inspections under the Pennsylvania Uniform Construction Code. For clarity before you start, contact Upper Dublin Code Enforcement.

A simple sequence that works

• Inspect and note the worst drafts.
• Schedule a PECO assessment or a blower‑door audit.
• Seal the attic floor and rim joist first, then major penetrations.
• Add insulation where performance is lacking, especially in the attic.
• Seal ducts in unconditioned spaces and address the attic hatch.
• Verify with a post‑work test or targeted checks.
