Attic Insulation — Assessment, Air Sealing & Upgrade

Warmer in winter, cooler in summer, lower bills year-round. We bring your attic up to modern standards with proper air sealing, right-sized insulation, and clean details that keep dust out and comfort in.

What we install

• Blown-in cellulose for dense, even coverage and good sound control
• Blown fiberglass for high R-value without settling
• Batt insulation where access is tight or for knee walls and vertical faces
• Insulated attic hatch and weatherstripping so the lid isn’t a weak spot

Why it matters

• Comfort: evens out upstairs temperatures and cuts drafts
• Efficiency: lowers HVAC runtime and helps ducts work better
• Air quality: air sealing stops attic dust and hot air from leaking into rooms
• Durability: keeps moisture and heat off framing, drywall, and finishes

Done right (the essentials)

• Air seal first: seal top-plate gaps, can lights, chases, and around pipes before insulating
• Right R-value: target the R-level appropriate for your climate and code (we verify on site)
• Ventilation preserved: install baffles at eaves so soffit vents stay clear; confirm ridge/gable venting
• Clearances: keep safe gaps around flues, heat sources, and electrical boxes; dams at the hatch
• Duct check: note exposed or leaky ducts and recommend sealing or burying where appropriate

Installation process

• On-site assessment — measure existing R-value, check ventilation, find air leaks and safety clearances
• Plan and written pricing after the visit — material choice, target R-value, air-sealing scope, hatch upgrades
• Prep & air sealing — protect finishes, seal penetrations, install baffles, build dams
• Install insulation — blow or place to the specified depth, level and verify coverage
• Final check — label R-value, photograph coverage, review care and future service tips

Signs you need an upgrade

Rooms too hot or too cold • Dirty streaks at ceiling fixtures • High energy bills • Visible joists in the attic • Dust drafts from the hatch.
