Nemo's cabins and ranches sit deep in the Black Hills on crawl spaces and over shops, where the semi-arid mountain climate swings from 20-below winters to summer afternoons that push heat through every gap and seam. Spray foam insulation and air sealing are not luxuries here, they are the difference between a heating bill that makes sense and one that doesn't, between a shop that stays dry and one that sweats and drips every chinook thaw.

Rapid City Spray Foam Insulation has been serving Nemo and the surrounding Hills since 2012. Our crews understand the specific challenges of seasonal cabins, crawl space moisture, and metal-frame buildings that frost inside and leak warm air in winter. We show up with the right equipment, the right crew insurance, and the knowledge to get it right the first time.

Spray Foam Insulation in Nemo (57759)

Nemo's building stock tells the story of the Hills. Log and frame cabins built decades ago sit on shallow crawl spaces with no insulation and no vapor barrier. Ranch-style homes and shops run open rim joists and band joists that bleed heat straight into the cold ground. Metal buildings and barndominiums, newer and older alike, have uninsulated walls and roofs that frost inside on winter mornings and sweat on spring thaws. The terrain is steep, the foundation access is tight, and moisture moves up from the ground almost year-round in the semi-arid climate.

Closed cell spray foam seals crawl spaces and stops vapor drive. Open cell foam fills cavities in walls and rim joists and breathes. Both are measured in board feet, sprayed to a specified thickness, and backed by a written estimate with the R-value and thickness specs that matter. We have been installing both in Nemo and the Rapid City area for over a decade. We know the local building code, we coordinate with the local building official, and we leave your property clean.

Our services in Nemo

How a Job Works in Nemo

We start with a free on-site assessment. We look at the space, measure what has to be covered, ask about the current insulation and any moisture or condensation you have seen, and listen to what you want to accomplish. We give you a written estimate with the R-value, thickness, material choice (open cell or closed cell), and the total cost before we spray anything.

On the day of the work, our fully insured crew arrives with the spray rig and all safety gear. We set up mechanical ventilation to manage the smell during cure. We protect your floors and belongings. We spray the foam to the thickness specified in the estimate, control the ratio and drum temperature, and air seal the gaps around rim joists, band joists, and ductwork. If insulation has to come out first because it is wet or contaminated, we remove it and haul it away. We do not spray over a wet or leaking substrate, and we walk away if the moisture is not fixed first.

After the foam cures, we do a final walkthrough with you, answer any questions, and clean up the work site. We tell you the re-entry window, which is typically twenty-four to forty-eight hours. Your property is left clean and ready to use.

Attic spray foam in Nemo typically runs from $1.50 per square foot for open cell to $1.20 per board foot for closed cell, depending on the thickness and R-value you need and whether existing insulation has to be removed first. Crawl space work usually starts at $2,500 and goes up with the square footage and the depth of the space. Rim and band joist sealing runs from $650 and up. Wall injection foam for closed cavities in older frame homes runs from $2 per square foot. Metal building and barndominium spray foam runs from $1.75 per square foot. Insulation removal is from $950. The final cost depends on the area to cover, the R-value and thickness required by code at your address, whether you choose open or closed cell, and whether existing insulation or contaminated material has to come out first.

My cabin in Nemo sits on a crawl space with no insulation and no vapor barrier. In spring, the floor is cold and the air smells damp. What does spray foam do?

Closed cell spray foam seals the crawl space and stops vapor drive from the ground. We spray the walls, the rim joist, and the band joist. The foam creates an air barrier and a vapor barrier in one pass. The floor stays warmer, the smell goes away, and you stop losing heat through the crawl space. We also make sure any standing water or active leaks are dealt with first, or we do not spray. Call (605) 519-6148 and we will assess the crawl space and give you a written estimate.

My shop in Nemo is a metal building. In winter it frosts inside, and in spring every thaw drips water on the floor. Can spray foam fix this?

Frost and drip happen because the metal shell has no insulation and no air barrier. Warm air from inside hits the cold metal and condenses. Spray foam on the interior walls and roof decking stops the condensation by keeping the metal warm. We spray closed cell foam to a thickness that meets code, and we seal all the seams and gaps. The frost stops, the drip stops. If there is standing water or active roof leaks, those have to be fixed first. Call (605) 519-6148 to schedule a site visit.

I have an older log cabin in Nemo with balloon-framed walls and no cavity insulation. How much does wall injection foam cost?

Wall injection foam runs from $2 per square foot. The final cost depends on the square footage of wall to cover, the thickness and R-value required by the local building code, and whether we have to remove old insulation first. We drill small holes, inject the foam, and seal the holes. A typical cabin wall might run $3,000 to $6,000, but we give you a free written estimate after we measure and assess the walls. Call (605) 519-6148.

Who decides what R-value and thickness of spray foam I need in Nemo, and who inspects the work?

The energy code and building code in force at your address set the R-value and thickness requirements. The building official for Nemo and Pennington County enforces the code and inspects the work. We follow the code at your address and provide a written estimate with the R-value and thickness specs. You can verify the local code requirements and permitting rules with the official city site at https://www.pennco.org. We help you navigate what applies at your property, but the building official has the final say.

I live in my Nemo cabin year-round. Can you spray foam while I am home, and how long before I can use the space again?

Yes, we can spray while you are home. We set up mechanical ventilation during the cure to manage the smell. The space is safe to re-enter after twenty-four to forty-eight hours, depending on temperature and humidity. We tell you the exact re-entry window when we finish. Keep windows open and use the ventilation we set up. The smell fades as the foam cures. If your cabin is in a master-planned community with HOA rules, let us know and we will coordinate any exterior work with the HOA requirements.

Is your crew fully insured for spray foam work in Nemo?

Yes. We carry general liability and workers' compensation insurance. Our crew is fully insured for spray foam insulation and air sealing work. You can verify any contractor's insurance before you hire. We are happy to discuss our coverage. Call (605) 519-6148.

When is the best time of year to spray foam a cabin or shop in Nemo?

We work year-round. Interior crawl space and rim joist work can happen any time because it is sheltered. Attic and metal building work is easier in mild weather, but we spray in winter too. If you are planning a big project, late spring through early fall is ideal because the weather is stable and the cure time is faster. But if you have a cold shop that is costing you money or a damp crawl space in winter, do not wait. Call (605) 519-6148 and we will find a time that works.
