If your heating and cooling bills keep climbing every year, your siding might be part of the problem. At Tevelde and Co., we’ve worked with homeowners across Nebraska who were shocked to learn how much money was slipping through their walls. Replacing old, worn-out siding with modern insulated materials can lower energy costs by up to 20%, and in some cases even more.
In this helpful guide, we will walk you through how siding affects energy efficiency, what signs to watch for, and which materials perform best in our climate.
When siding begins to pull away from the wall, crack, warp, or allow moisture behind the exterior surface, your home loses more than curb appeal. It can also lose comfort and energy efficiency. Old siding can make a home harder to heat, harder to cool, and more expensive to maintain.
If your home feels drafty, your utility bills keep climbing, or your siding has reached the end of its useful life, a properly installed siding replacement can help improve your home’s thermal performance while giving your exterior a clean, finished look. The exact savings will depend on your home’s age, wall construction, current insulation, window condition, air leaks, and the type of siding system installed.
Your home's exterior needs to work as a complete system in order to be energy efficient. Siding is the outermost layer, but behind it sits house wrap, sheathing, insulation, and framing. When any part of that system breaks down, heat or cooled air escapes, and outdoor air sneaks in.
Older homes in Nebraska often have siding installed decades ago, before modern energy standards existed. Many of those houses were built with little or no wall insulation. Others have insulation that has settled, gotten wet, or simply aged out of usefulness.
Damaged siding may allow outside air to move through gaps, seams, damaged panels, or poorly sealed edges. Moisture can also find its way behind loose or cracked siding, which can reduce the effectiveness of wall insulation and create hidden damage over time. In Nebraska, where homes deal with hot summers, freezing winters, strong winds, hail, and rapid temperature changes, siding performance matters.
A siding replacement project gives us a rare chance to fix all of that at once.

Many homeowners first notice an issue because the house does not feel as comfortable as it used to. Rooms may feel cold near exterior walls in the winter or overly warm in the summer. The HVAC system may run longer, yet the indoor temperature still feels uneven.
Your siding may be contributing to energy loss if you notice:
These issues do not always mean the siding is the only problem. They do mean your exterior system deserves a closer look. At Tevelde and Co., we inspect the condition of your siding, trim, and surrounding exterior components so we can recommend the right solution for your home.
At Tevelde and Co., we focus on the details that affect long-term performance. Below are the ways that new siding improves energy performance:
R-value measures how well a material resists heat flow. Higher is better. Standard vinyl siding has almost no R-value on its own. Insulated vinyl siding, which has rigid foam bonded to the back, adds R-2 to R-4 to your wall assembly. That might sound small, but it makes a real difference when paired with existing wall insulation.
Stopping air leaks is one of the fastest ways to lower your heating and cooling costs. Old siding often has gaps around windows, doors, and corners where air leaks in and out. During a replacement, we seal those gaps with modern house wraps, flashing tape, and caulk.
Dry walls insulate better than wet ones (not to mention the long-term effects of water damage). A proper siding installation project includes a home drainage system, flashing at every penetration, and sometimes a rain screen for added protection.
Lighter siding colors reflect more summer sun. Some fiber cement and steel products come with reflective pigments that reduce heat absorption even in darker shades. In Nebraska, where July afternoons regularly hit the mid-90s, this matters.
When siding comes off, we can inspect the sheathing and insulation underneath. If the insulation is thin, damaged, or missing, we can add rigid foam board or blown-in insulation before the new siding goes up. I've had projects where adding an inch of foam board cut a client's winter heating bill nearly in half.
New siding can help reduce energy consumption. The exact numbers vary based on your home's age, size, current insulation, and the products you choose. That said, here's what I've seen from actual Nebraska projects:
Check with your local utility, because some Nebraska providers (like OPPD and NPPD) have offered rebates for better insulation upgrades tied to siding work. The federal Energy Efficient Home Improvement Credit may also apply to certain insulation materials installed during your project.
We've been installing siding in Nebraska for years, and we know what works here. Our crews are trained on the specific techniques each manufacturer requires for warranty coverage. We're licensed, insured, and carry certifications from James Hardie, LP, and major vinyl brands.
Every project comes with a written estimate, a clear replacement timeline, and a warranty on both materials and workmanship. Financing options are available for homeowners who want to spread the investment over time.
The cost of most siding replacement projects fall between $8,000 and $30,000 depending on home size, material, and any repairs needed underneath. Insulated vinyl sits at the lower end, while premium fiber cement reaches the higher range
Insulated vinyl lasts 30 to 40 years with minimal maintenance. Fiber cement can last 40 to 50 years or more. Steel and engineered wood fall somewhere in between.
Vinyl becomes brittle below about 40 degrees, so we schedule most projects between April and November. Fiber cement is more forgiving and can go up in colder weather if conditions allow.
Possibly. The Federal Energy Efficient Home Improvement Credit covers certain insulation upgrades, and some Nebraska utilities offer rebates. We can point you toward current programs during your consultation.
Not always, but if your home was built before 1980 or you’ve noticed comfort issues, it’s worth inspecting during our consultation. The labor cost to add insulation is much lower when the siding is already off and the insulation can also help reduce utility bills.
If your siding is aging, damaged, or just not doing its job keeping your home comfortable, now is the time to think about a energy-efficient siding replacement. A Tevelde and Co. siding contractor will come out, look at your home, and give you an honest assessment of what needs to happen and what it will cost. Schedule your free siding and energy-efficiency consultation today. We serve homeowners across Nebraska and would be glad to help you figure out the right next step for your home.
