Most homeowners don't know their attic is the #1 source of energy loss — until they see the bill. Here's what to watch for.
Conditioned air escaping through attic gaps means your furnace and AC work overtime — and you pay for it.
If certain rooms never warm up, air leaks at the attic floor may be pulling cold air down into your living space.
Heat escaping from a poorly sealed attic melts snow on your roof, then refreezes at the eaves — causing serious damage.
Warm, humid air rising into the attic condenses on cold surfaces. Over time, this leads to rot, mold, and structural damage.
Improper airflow traps heat in summer and moisture in winter. Both scenarios shorten your roof's lifespan.
If your bath fan dumps warm, moist air directly into the attic rather than outside, moisture damage builds silently.
Insulation alone can't stop air movement. Without proper air sealing, even well-insulated attics bleed energy.
Stuffy in summer, freezing in winter. Your attic affects your home's comfort more than any other single area.
Every job starts with a clear-eyed inspection. We identify exactly what's wrong and give you honest recommendations — no upselling, no guesswork.
We locate and seal the gaps, cracks, and penetrations where conditioned air escapes — the single most cost-effective improvement in most Wisconsin homes.
Quantifies exactly how leaky your home is using calibrated pressure diagnostics. Available as a standalone service or add-on to attic work. Additional fee applies.
We correct ventilation imbalances that cause moisture buildup, premature roof damage, and uncomfortable rooms — fixing the source, not the symptom.
If your bath fan is exhausting into the attic, we reroute it to vent properly to the exterior — eliminating a major hidden source of moisture damage.
Proper soffit-to-ridge airflow keeps your attic dry in winter and cooler in summer. We diagnose and correct blocked or inadequate airflow paths.
