Old, damaged, or pest-contaminated insulation does more harm than good. We remove it cleanly so your upgrade starts on a solid foundation.

Missouri summers push moisture into crawl spaces, causing mold and wood rot. Crawl space insulation stops that cycle before it damages your home's structure.

Feel cold air near outlets or walls on a January day? Wall insulation fills the cavities that batts miss and keeps conditioned air exactly where it belongs.

Insulation slows heat, but air sealing stops the drafts. Sealing gaps around pipes, outlets, and framing makes every other insulation upgrade work better.
Learn MoreReach out by phone or through the contact form. You tell us the age of your home, which areas you are concerned about, and any problems you have noticed - high bills, drafty rooms, uneven temperatures. We will ask a few questions to come prepared and, in most cases, can schedule a visit within a few days. We respond to every inquiry within 1 business day.
A contractor visits your home and walks through the areas you want insulated - attic, crawl space, basement, walls. We measure what is already there, look for moisture or damage, and identify where air is escaping. You get a written estimate that spells out exactly what we recommend, what materials we will use, and the total cost. No pressure to move forward.
On the day of the job, we protect your home, seal gaps before insulation goes in, and install everything to the correct depth and coverage. Before we leave, we walk you through the finished work and hand you documentation of what was installed. Most homeowners notice a difference in comfort within the first heating or cooling cycle.
Missouri requires insulation contractors to hold a valid state license. We carry full insurance coverage on every project. Ask for our license number before signing anything - we will provide it without hesitation. That documentation also protects you at resale or during an insurance claim.
We do not quote over the phone without seeing your home first, because attic and crawl space conditions vary too much to price accurately from a description. Our estimates are written, itemized, and free. Take your time comparing - we do not pressure anyone into signing on the spot.
We are a local business, not a regional franchise. We know St. Joseph's housing stock - the pre-1940 brick homes near downtown, the post-war neighborhoods on the Southside, the newer subdivisions on the city's edges. That familiarity shows in how we approach each job.
Before we leave, we walk you through the completed work - photos from the attic, a look at the crawl space, whatever it takes for you to see what was done. You also get written documentation of the materials installed, which you need for federal tax credits and utility rebates. No guessing whether the job was done right.

We had an upstairs bedroom that was unbearable every summer. After they insulated the attic and sealed the gaps around the hatches, the whole second floor is actually comfortable now. Took one day and was done right.
Marcus T., St. Joseph - Attic Insulation
Called on a Monday, had someone out to look at the crawl space by Wednesday, and the spray foam was done by Friday. The musty smell is gone and our heating bill was noticeably lower the very next month.
Diane R., Kearney - Crawl Space Insulation
I was nervous about hiring someone for blown-in insulation because I had no idea how to tell if it was done correctly. They walked me through the attic before they left and showed me the depth markers. That was exactly what I needed.

If you can see the wooden joists across your attic floor, your insulation depth is almost certainly too low for St. Joseph's climate. The U.S. Department of Energy places this region in a zone that requires significantly more insulation than most older homes currently have. A contractor can measure what is there and tell you exactly what is missing.
Yes - and often a bigger one than adding more insulation. Air sealing closes the gaps where outside air sneaks in around pipes, electrical boxes, and framing joints. In older homes, those gaps can account for as much heat loss as a large open window. The U.S. Department of Energy recommends doing both air sealing and insulation together for the best results.

St. Joseph gets hot, humid summers, and ground moisture rises into crawl spaces year-round. That moisture causes wood rot, mold, and pest problems over time. Closed-cell spray foam applied to crawl space walls and rim joists creates a hard barrier that moisture cannot penetrate - something batts and blown-in material cannot match. Catching this early is far less expensive than repairing structural damage later.
Almost certainly, yes. Homes built before 1980 were constructed under much older energy standards. Many have original thin insulation that has settled, compressed, or degraded over decades. If you have never had an insulation assessment and your home is more than 40 years old, there is a good chance you are heating and cooling rooms with insulation that is performing at a fraction of what it once did.
Yes. The federal government currently offers a tax credit worth up to 30% of the cost of qualifying insulation improvements, capped at $1,200 per year. This applies to materials installed in your primary home. Your contractor should provide the product documentation you need to claim it. Ask about this before you sign any contract - it can meaningfully reduce your out-of-pocket cost.
Properly installed spray foam can last the lifetime of the home. It does not sag, settle, or compress the way fiberglass batts sometimes do over decades. The main exception is foam exposed to prolonged UV light, which can degrade the surface - any exposed foam in a space that gets direct sunlight should be covered with a protective coating or drywall. For everything else, it is essentially a one-time investment. Read more from the Spray Polyurethane Foam Alliance.
St Joseph Insulation is a licensed insulation contractor based in St. Joseph, MO, serving 12 communities across northwest Missouri and northeast Kansas since 2023. Our contractors hold valid Missouri state licenses issued through the Missouri Division of Professional Registration, and every job is fully insured. Since opening, we have completed insulation projects across 16 service categories - from spray foam and attic upgrades to commercial insulation and vapor barrier installation.
If existing insulation is dry, pest-free, and undamaged, you can usually add on top of it. If it is wet, moldy, or infested, remove it first - installing new material over a problem hides it rather than fixing it.
For most blown-in attic work, yes - you can stay home. Spray foam applications require you to leave for a few hours (or up to a day for large jobs) while the foam cures and any odor clears.
Most homeowners in Missouri's climate see meaningful bill reductions within the first heating or cooling season. Full payback on material and labor typically falls between 3 and 7 years, with the insulation continuing to perform for decades after.

St. Joseph, MO is a city of roughly 73,000 people on the east bank of the Missouri River in northwest Missouri, and one of the largest cities in the region. The city is home to major employers including Mosaic Life Care, Missouri Western State University, and Triumph Foods, which means a lot of residents have long-term roots here and invest in maintaining their homes. The Pony Express National Museum marks the city as the starting point of the original 1860 Pony Express route - one of the most recognized landmarks in town.
St. Joseph has a large share of older housing. The city grew rapidly in the late 1800s and early 1900s, and many of those homes are still occupied today. You will find two-story wood-frame houses, brick foursquares, and Victorian-era homes throughout the older neighborhoods near downtown. The streets along Noyes Boulevard and the historic Southside are known for larger, older homes that were built for the city's merchant and professional class - many of them well over 100 years old. Homes of that era were built before modern energy standards existed and almost always have insulation that is well below today's recommended levels. The city also sits right on the Missouri River, and low-lying areas near the water can face drainage and moisture issues that require the right approach to crawl space and basement insulation.
From the historic Southside to the newer subdivisions near the city's edges, our team works on homes throughout St. Joseph. Whether you are in one of the large older homes off Noyes Boulevard or a newer ranch on the south side, we know what these homes need - and we bring the same thoroughness to every job.
