02

We Answer the Phone & Provide Fast Quotes

03

The Bid you Sign is the Bill you Pay

Line-item quotes from your plans, and the bid you sign is the bill you pay. If we find something unexpected, you get a photo and a conversation before it becomes a charge — the decision stays yours. That's been the rule since 2012.

04

On Schedule & Reachable

A late sub doesn't cost you a day — he costs you every trade scheduled behind him. When we commit to a date, it's real: confirmed schedule, a text when we're rolling, a crew that shows when it said it would. when you call, we answer.

Owner-Builder Partner

Acting as your own general contractor? Pacific Insulation & Restoration works directly with owner-builders and custom home builders across Spokane County and North Idaho as your insulation subcontractor — handling wall insulation, attic insulation, vaulted ceiling insulation, sound batts, and rim joist air sealing from framing to final inspection. We read your plans, do the insulation takeoff, quote R-21 walls, R-38 vaults, R-49/R-60 attics, and R-30 floors to match Washington State Energy Code (WSEC) requirements, and help you choose between the prescriptive path and component performance options so you pass your insulation inspection the first time. We schedule around your electrical and plumbing rough-in, show up when the drywallers are booked, and provide the certificate of insulation and documentation your building department. Blown-in cellulose, dense-pack walls, batts, and vapor barriers — one licensed, insured sub you don't have to chase. Free bids from your plans.

What Owner-Builders Worry About — Handled

Building your first home — or acting as your own general contractor — means carrying every worry at once, so here's how we take the insulation ones off your list. Our bids are line-itemed from your actual plans, and the bid you sign is the bill you pay: no "that'll be extra," no budget surprises. When we give you a date, we show up on it — we know one late sub cascades through your drywall, paint, and construction loan interest, so "on our way" means on our way. We've passed hundreds of Washington State Energy Code inspections, and we quote your R-21 walls, R-38 vaults, and R-49/R-60 attics to the compliance path your plans actually use, so you pass the first time. Not sure when insulation fits in your build? We'll tell you: after your electrical, plumbing, and HVAC rough-ins are inspected, before drywall — and we'll coordinate directly with your other trades

Best Insulation for New Construction

Choosing the right insulation for your new build is essential to ensure efficiency, meet building codes, and provide long-term benefits. At Pacific Insulation, we offer a variety of solutions based on your specific project needs.


R21 Wall Insulation

For exterior walls, R21 insulation is a top choice. This level of insulation exceeds the traditional R13 or R15 batts, providing better thermal performance and energy savings. We install fiberglass batts, blown cellulose, or spray foam to meet your building’s insulation requirements.


R60 Attic Insulation

Proper attic insulation is crucial for energy efficiency, especially in Spokane’s cold winters. The International Code Requirements for Washington recommend a minimum of R49 to R60 for attics. At Pacific Insulation, we specialize in blown cellulose and fiberglass, ensuring your attic meets or exceeds these standards.

Meeting International Code Requirements for Washington

Building codes are essential for safety and efficiency. Pacific Insulation stays up to date with the latest International Code Requirements for Washington, ensuring that your new construction project is fully compliant.


  • Exterior walls require R21 insulation
  • Attics need R49 to R60 insulation
  • Crawl spaces should be properly insulated to prevent heat loss
  • Proper air sealing is required to enhance efficiency and prevent drafts


By choosing Pacific Insulation, you can rest assured that your home will meet or exceed Idaho’s insulation codes.

Types of Insulation We Offer

Blown Cellulose & Baffles

Blown-in cellulose is one of the most effective and eco-friendly insulation solutions for attics and walls. Baffles are installed to maintain proper airflow and prevent moisture buildup, enhancing the performance of your insulation system.

Rigid Foam Insulation

For the highest R-value per inch, rigid foam is an excellent choice. It provides superior air sealing, moisture resistance, and thermal performance, making it ideal for walls, vaulted ceilings and even crawl spaces.

Crawl Space Insulation

Proper crawl space insulation is crucial to prevent energy loss and moisture problems. We offer rigid foam board, fiberglass batts, and spray foam solutions to keep your home warm and energy-efficient from the ground up.

Licensed, Bonded, Insured and On Schedule

Choosing a licensed & insured contractor ensures that your project is in the hands of professionals. Pacific Insulation is fully licensed and insured, protecting you from any risks while guaranteeing high-quality workmanship.
