Do I need an energy audit first?

Yes — an audit is required before weatherization to qualify for utility rebates and establish your baseline air leakage number.

Can I just add insulation without air sealing?

You can, but it's significantly less effective. Sealing first means insulation performs at rated R-value — 30-50% better results.

The most cost-effective upgrade for most Maryland homes

25% of your home's energy loss comes from air leakage. We seal the leaks first, then insulate to R49 — so every dollar of insulation actually performs as intended.

The Right Sequence

Why air sealing comes first

Most contractors skip straight to adding insulation. That's like putting on a sweater full of holes. We seal air leaks first, then insulate — so every dollar works as hard as it should.

Diagnostic Testing

Blower door quantifies how leaky your home is. Thermal imaging and smoke testing pinpoint exactly where.

Targeted Air Sealing

We seal top plates, rim joists, plumbing and electrical penetrations, recessed lights, attic hatches, and duct connections.

Insulation Installation

Blown-in fiberglass or cellulose to R49 in the attic. Sealed homes hold conditioned air, so insulation performs at rated value.

Verification Testing

Post-work blower door confirms air leakage reduction. Before and after numbers documented — that's how we qualify your rebate.

What We Do

Comprehensive weatherization services

Attic Air Sealing

Sealing top plates, wire and pipe penetrations, recessed lights, attic hatches, and duct connections — where most leakage occurs.

Attic Insulation to R49

Blown-in fiberglass or cellulose. If existing insulation is damaged or insufficient, we remove it first, air seal, then install fresh.

Rim Joist Insulation

Spray foam or rigid foam at the rim joist — a major cold air infiltration source in basements, often overlooked by other contractors.

Insulation Removal

Old, compressed, or contaminated insulation removed with industrial vacuum before re-insulating for a clean, effective installation.

Duct Sealing

Leaky ductwork wastes 20-30% of heating and cooling. We test duct leakage and seal with mastic for lasting performance.

Crawlspace Encapsulation

Vapor barriers, insulation, and sealing for crawlspaces to control moisture, prevent mold, and eliminate cold floors.

Questions

Air sealing & insulation FAQ

Yes — an audit is required before weatherization to qualify for utility rebates. It establishes your baseline air leakage number and identifies all specific targets.

Most projects take 1-2 days. Air sealing alone is usually one day. If insulation removal is needed, add another day.

Rarely an issue in Maryland homes. Most are so leaky that even after comprehensive sealing, they have plenty of ventilation. We follow BPI: "seal tight, ventilate right."

You can, but it's significantly less effective. Air moving through insulation carries heat right past it. Sealing first means insulation performs at rated R-value — 30-50% better reduction than insulation alone.
