Cold floors and high heating bills often trace back to an uninsulated crawl space - we seal it from the ground up.

You can add insulation all day, but if air is moving freely through gaps, it cancels out much of the benefit - sealing comes first.
Learn MoreReach out by phone or through our contact form. We will ask a few basic questions about your home and what you have noticed - cold rooms, high bills, or a specific area you want addressed. We respond within 1 business day and can usually get you scheduled within the same week.
We come to you. A crew member walks your attic, crawl space, or wherever the work is needed, measures what is already there, checks for air leaks or moisture issues, and answers your questions in plain terms. You get a written estimate before we leave - no pressure, no surprises.
On installation day the crew handles everything - prep, sealing, installation, and cleanup. Most residential jobs finish in a single day. We walk you through the completed work before leaving so you can see exactly what was done and confirm it meets your expectations.
We carry full liability insurance on every project. You are protected if anything goes wrong - and we will provide proof of coverage before work starts, no questions asked.
We do not quote over the phone because attic conditions vary too much to be accurate. We come out, assess your home, and hand you a written estimate. You decide from there - no sales pressure.
We live and work here. We know the housing stock, the climate, and the specific challenges that come with central Nebraska winters. You are talking to neighbors, not a call center.

They came out within two days of my call, went up in the attic, and explained exactly what was missing. The blown-in insulation job was done in one morning, and I noticed a real difference in how warm the upstairs stayed that first week.
Mike T., Kearney - Attic Insulation
I had spray foam done in my crawl space and rim joists last fall. The crew was on time, explained the process before they started, and cleaned up completely when they left. My basement is noticeably warmer this winter.
Sandra R., Grand Island - Spray Foam Insulation
We had old insulation pulled out and replaced in the whole attic. The estimate matched the final bill exactly. No surprises, no pressure to add extra services. I would hire them again without hesitating.

Grand Island sits in Climate Zone 5, where winters regularly drop below zero and summers push past 95 degrees. That swing puts constant pressure on your home. Attic insulation recommendations for this zone are substantially higher than for warmer states.
Grand Island regularly sees sustained winds of 15 to 25 mph in winter. Wind pressure forces cold air through every small gap in your home's exterior. Insulation slows heat transfer, but only air sealing stops air from moving - which is why both steps matter here.
Old insulation that is compressed, wet, or contaminated with mold no longer performs. Adding new material on top traps the problem underneath. A contractor should assess what is already there before recommending removal versus a top-up.
Closed-cell foam acts as both insulation and a vapor barrier, making it the correct choice for crawl spaces and basement walls exposed to moisture. Open-cell foam is more cost-effective for interior walls and attics where moisture is not the primary concern.
As of 2025, homeowners adding insulation to an existing home can claim 30 percent of material costs, up to $1,200 per year, through the federal Energy Efficient Home Improvement Credit. Ask your contractor for the product documentation needed to claim it. IRS Energy Efficient Home Improvement Credit.
If you can see the wooden joists across your attic floor, the insulation is too thin for Nebraska winters. Compressed, matted, or visibly wet insulation has also lost significant effectiveness. Either condition means heat is escaping through your ceiling every month.
For general guidance on insulation levels by climate zone, the U.S. Department of Energy Energy Saver guide is the most reliable starting point.

Learn more about usWhen you need both insulation and moisture or air barrier performance in one step - typically in crawl spaces, rim joists, and basement walls. Blown-in is usually the more economical choice for open attic floors.
For most homes in Grand Island, insulating the attic floor is the standard approach. Roof-line insulation makes sense if you plan to use the attic as conditioned living space - otherwise, floor insulation is more cost-effective.
Go into your attic and look at the floor. If you can see the tops of the wooden joists, you are below the recommended level for Nebraska's climate. A contractor will measure and tell you exactly how much is needed.

Grand Island is the fourth-largest city in Nebraska, with about 53,000 residents in the Platte River valley near the center of the state. It is the county seat of Hall County and serves as a regional hub for shopping, healthcare, and services for a wide area of central Nebraska. You can read more about the city on Wikipedia or visit the City of Grand Island website.
The city grew up as a railroad town, and many of its established neighborhoods near downtown reflect that era of development. Homes near Fonner Park and the Stuhr Museum of the Prairie Pioneer tend to be older ranch-style homes from the 1950s and 1960s - many of which were built with minimal insulation by today's standards. Grand Island is also home to the Nebraska State Fair, which has been held at Fonner Park every August since moving from Lincoln in 2010.
A large share of the city's housing was built before modern energy codes took effect, which means many homeowners are running on original insulation that is now decades old. Grand Island Insulation works across the city - from older in-town neighborhoods to newer subdivisions on the north and west sides - and we understand what each type of home needs. If your home is in Grand Island or the surrounding area, we are already familiar with the neighborhood.
