| Service | Price | Details |
|---|---|---|
| Attic Spray Foam Insulation | From $1.50/sq ft | Sioux City attics swing between hot humid summers and cold windy winters along the Missouri River. We spray closed cell foam across the roof deck in older Morningside homes and newer builds toward Sergeant Bluff, sealing the attic against heat gain and winter drafts. |
| Closed Cell Spray Foam Insulation | From $1.20/board ft | Closed cell foam stands up to the damp basements and hillside lots found across the Loess Hills. We use it in rim joists, crawl spaces and basement walls around Woodbury County to block moisture and add rigidity on these hillside foundations. |
| Open Cell Spray Foam Insulation | From $0.55/board ft | Open cell foam fills attic rafters and interior walls across Sioux City's mid-century ranches. It expands to seal odd framing bays in homes across Morningside and the hills above downtown, cutting sound and softening the swing between humid summers and cold winters. |
| Wall & Injection Foam Insulation | From $2/sq ft | Wall injection foam fills closed cavities in older homes above downtown Sioux City without opening the drywall. We drill small holes from outside or inside, inject foam into the cavity, and patch so the wall handles another cold Siouxland winter. |
| Crawl Space Spray Foam Insulation | From $2,500 | Some newer additions toward Sergeant Bluff sit on crawl spaces that trap humid air and damp winter cold. We seal the space and spray foam across the walls to stop the moisture that follows summer storms across Woodbury County. |
| Rim Joist & Band Joist Spray Foam | From $650 | Rim joists lose heat fast in Sioux City's full basements, especially on hillside lots in the Loess Hills. We spray closed cell foam along the band joist to block drafts and stop winter condensation before it reaches the floor joists above. |
| Garage Spray Foam Insulation | From $1,200 | Garages across Sioux City take the full swing from hot humid summers to cold windy winters. We foam the walls and ceiling, including rooms above garages in newer Sergeant Bluff subdivisions, to keep the space usable year round. |
| Metal Building & Barndominium Spray Foam | From $1.75/sq ft | Shops and farm buildings across Woodbury and Plymouth counties sweat without closed cell foam on the walls. We spray the interior of metal buildings and barndominiums to stop condensation that forms when humid summer air meets cool metal. |
| Commercial & New Construction Spray Foam | Free commercial estimate | Commercial projects across Siouxland face the same hot humid summers and cold windy winters as area homes. We work with contractors on new builds and retrofits across Woodbury and Plymouth counties, sizing foam systems to the building and its use. |
| Insulation Removal | From $950 | Older homes in the hills above downtown and in Morningside often carry flattened, decades-old attic insulation. We remove it along with any rodent waste or damage, clearing the attic deck so new foam bonds directly to clean wood. |
| Insulation Replacement & Re-Insulation | From $2,800 | After removal, older Sioux City attics need fresh insulation for the next heating season. We spray new closed cell or open cell foam across the roof deck, sized for attics in Morningside and the subdivisions toward Sergeant Bluff. |
| Air Sealing | From $650 | Air sealing stops the stack effect that pulls cold winter air through top plates in Sioux City homes. We seal penetrations, top plates and rim joists in homes from downtown's hillside streets to the newer subdivisions toward Sergeant Bluff. |
What Affects the Price
- Project Size and Square Footage : Larger projects typically cost less per unit because material and labor are spread across more area. A 500 sq ft attic will have a different per-square-foot rate than a 2,000 sq ft application.
- Foam Type Selection : Closed cell foam ($1.20/board ft) provides higher R-value and moisture resistance, while open cell foam ($0.55/board ft) is more budget-friendly and better for interior wall applications where vapor permeability is desired.
- Site Accessibility and Conditions : Attics with limited access, crawl spaces with low clearance, or projects requiring equipment setup may involve additional labor. Existing insulation removal also adds to the overall project cost.
- Existing Insulation and Preparation : If your home requires insulation removal ($950+) or replacement ($2,800+) before new foam application, this preparation work is factored into your final quote.

Pricing FAQ
Why does spray foam insulation cost more than traditional fiberglass or cellulose?
Spray foam creates an air seal while insulating, preventing drafts and moisture infiltration that other materials cannot address. This superior performance, combined with professional application and lasting durability, justifies the investment. Many homeowners recover costs through lower energy bills within 5-10 years.

Contact Sioux City Spray Foam Insulation at (712) 522-2693. Our team will ask about your project scope and schedule a convenient time to assess your home and provide a detailed, transparent quote.
What's included in the quoted price?
Our quotes include material costs, professional labor, equipment setup, and basic cleanup. We'll clearly outline any additional charges, such as insulation removal or structural repairs, before work begins so there are no surprises.
Do you offer financing or payment plans?
We recommend discussing payment options when you call for your estimate at (712) 522-2693. Many homeowners find that energy savings offset project costs over time, making spray foam a smart long-term investment.
Are there any seasonal price differences?
Pricing remains consistent year-round. However, scheduling your project during off-peak seasons (fall or early spring) may offer scheduling flexibility, so contact us to discuss timing that works best for you.
