A Better Seal for a More Comfortable Building
Shop Designs supplies and installs spray foam insulation, crawl space encapsulation, and waterproofing for homes, garages, pole barns, basements, workshops, and commercial buildings within about 50 miles of DeMotte, Indiana. One local crew handles the estimate, the prep, the application, and the cleanup.
Spray foam reaches the gaps and tight spaces that batt and blown-in insulation miss. Because it expands as it is applied, it seals around framing, corners, wiring, and penetrations in one pass. The result is a tighter building with fewer drafts, steadier temperatures, and better control over air and moisture.

Why Property Owners Choose Spray Foam
A good insulation job does more than keep a building warm. Spray foam helps reduce drafts, improve energy efficiency, stop unwanted air movement, and keep indoor temperatures consistent through Indiana winters and humid summers.
Because the foam bonds to the surface it is sprayed on, it also adds rigidity to walls and roof decks and will not sag, settle, or shift the way loose insulation can. That makes it a strong option for both new construction and existing buildings.
Open-Cell vs. Closed-Cell Spray Foam
Both types are sprayed in place and expand to seal the space, but they behave differently once cured. We recommend one or the other based on the building, the location, and what the space is used for.
Open-Cell Foam
Lighter, softer, and more flexible. Roughly R-3.5 to R-3.8 per inch, so it is applied thicker to reach a target R-value.
Good for interior walls, attics, and roof decks where sound dampening and air sealing matter and moisture exposure is low. Typically the lower-cost option per square foot.
Closed-Cell Foam
Dense and rigid. Roughly R-6 to R-7 per inch, so it delivers more insulation in less depth and adds structural strength to the surface it is sprayed on.
Acts as a vapor retarder, which makes it the usual choice for crawl spaces, basements, metal pole barns, and anywhere moisture is a concern.
Crawl Space Encapsulation, Waterproofing & Moisture Control
Shop Designs also provides crawl space encapsulation, crawl space waterproofing, and moisture control for basements, foundations, garages, shops, and commercial buildings across Northwest Indiana. Most of the homes we see in Jasper, Newton, Lake, and Porter counties sit on vented crawl spaces, and a damp crawl space is the usual reason for musty air, cold floors, and insulation that has sagged off the joists.
What crawl space encapsulation includes
Encapsulation seals the crawl space off from ground moisture and outside air so it behaves like part of the conditioned house. A typical job includes:
- A heavy-duty vapor barrier across the entire floor, run up the walls and sealed at the seams and piers
- Closed-cell spray foam on the rim joist and foundation walls, so the space is insulated and air-sealed in one step
- Sealing the foundation vents, access door, and pipe and wire penetrations
- A crawl space dehumidifier or conditioned-air supply where the space needs it
Crawl space and basement waterproofing
Every moisture problem is different, so we start by finding where the water is coming from. If water is getting in, whether it is seepage through the foundation, standing water after a storm, or a high water table, we address drainage and waterproofing first: interior drain tile, a sump pump, sealing foundation cracks, and grading or downspout fixes outside. Once the space is dry, we encapsulate and insulate it so it stays that way.
Signs you may need encapsulation or waterproofing: a musty smell in the house, humidity readings above 60% in the crawl space, condensation on ducts or pipes, cold floors in winter, mold on joists, insulation hanging down, or standing water under the house.
Spray Foam for Garages and Pole Barns
Garages, pole barns, and workshops are hard to heat and cool when air moves freely through metal siding, purlins, and roof panels. Spray foam bonds directly to the metal and framing, creating one continuous seal that makes the space comfortable and usable in every season and cuts down on condensation dripping from the roof.
Whether you are finishing a new building or improving an existing one, we can help determine the right foam, thickness, and approach for your space.
Insulating a garage or shop is often the first step in a bigger build-out. We also supply and install garage storage and flooring in Northwest Indiana, so one crew can insulate, organize, and finish the space.
What to Expect on Install Day
- Estimate and planWe review the building, confirm the foam type and thickness, and give you a written estimate. Photos and rough dimensions are enough to start.
- Prep and maskingWindows, doors, floors, and fixtures in the work area are covered. You clear the space of anything you do not want overspray on.
- ApplicationThe crew sprays in lifts to the planned depth. Most residential jobs are finished in a day; larger barns and commercial buildings can take longer.
- Cure, cleanup, and walkthroughFoam cures within hours. We tell you when the area is safe to re-enter (typically 24 hours), remove masking, clean up, and walk the job with you.

Common Questions About Spray Foam and Crawl Space Encapsulation
Do you work on homes and commercial buildings?
Yes. We provide spray foam insulation for residential and commercial projects of many sizes, from a single garage to full pole barns and commercial buildings.
Can you insulate an existing garage or pole barn?
Yes. Spray foam can be installed in many existing buildings as well as new construction. We will review the condition of the space before recommending the work.
Should I use open-cell or closed-cell foam?
It depends on the space. Open-cell is a good fit for interior walls, attics, and roof decks where sound and air sealing matter. Closed-cell is the usual choice for crawl spaces, basements, metal pole barns, and anywhere moisture is a concern, because it is denser and acts as a vapor retarder. We recommend one or the other during the estimate.
Does spray foam help with moisture?
Spray foam reduces air movement and can manage moisture when the correct product is used in the right location. Existing leaks or standing water should be evaluated separately, and may need a waterproofing solution in addition to insulation.
What is crawl space encapsulation?
Crawl space encapsulation seals the crawl space off from ground moisture and outside air. We install a heavy vapor barrier across the floor and up the walls, spray closed-cell foam on the rim joist and foundation walls, seal the vents and penetrations, and add a dehumidifier if the space needs one. The result is a dry, conditioned crawl space, which usually means warmer floors, less musty air, and insulation that stays put.
Do you waterproof crawl spaces and basements, or just insulate them?
Both. If water is getting in, we fix that first with drainage, a sump pump, foundation crack sealing, and exterior grading or downspout corrections. Then we encapsulate and insulate so the space stays dry. Insulating a wet crawl space without waterproofing it first just traps the moisture.
How much does crawl space encapsulation cost?
It depends on the square footage, how much waterproofing is needed before sealing, whether the space needs a dehumidifier, and how easy it is to access. We inspect the crawl space and give you a free written estimate that separates the waterproofing, vapor barrier, foam, and dehumidifier so you can see what each piece costs.
How much does spray foam insulation cost in Northwest Indiana?
Cost depends on the foam type, the thickness needed, the square footage, and how accessible the space is. Closed-cell costs more per inch than open-cell but delivers more R-value per inch. We provide a free written estimate so you can compare options before committing.
How long until I can use the space again?
Foam cures within hours, but the work area should stay clear while it off-gasses. We will tell you when it is safe to re-enter, which is typically 24 hours after application.
How do I get an estimate?
Send us a few details about your building, including the location, approximate size, and the areas you want insulated. Photos are helpful. We will follow up to discuss the project and schedule an estimate.
