In 2000, Luis hired Home Shield Coating® of Illinois to protect the cedar siding on his Chicago lake-front home. Twenty-five years later, one side of that home has faced Lake Michigan through every freeze-thaw cycle, every storm, and every summer sun the Midwest can throw at it — on the original coating. This is what that experiment looks like today, and the math on what a permanent coating actually saved him — no more 3-to-5-year repaint cycle.
If you own a cedar-sided home in the Chicago or Milwaukee metro, you already know the cycle: paint or stain, watch it fail in three to five winters, and pay to redo it. Luis’s 25-year experiment is exactly why Home Shield Coating® has become the longest lasting exterior paint alternative in Chicago, the leading Wisconsin cedar siding restoration alternative, and the coating of record for Chicagoland historic home exteriors and cedar properties across Milwaukee, Madison, and Waukesha County.
Home Shield Coating® Performance After 25 Years
Luis first hired Home Shield Coating® of Illinois over 25 years ago to protect the cedar siding on his home. He had been painting the exterior with typical standard paints every 3 to 5 years before deciding to invest in a more durable permanent solution. One side of his home faces Lake Michigan in Chicago, which exposes it to harsh weather conditions throughout the year. Home Shield Coating® is 17 times thicker than paint, making it an ideal defensive wall coating that protects exterior walls from Mother Nature’s harsh weather conditions.
Home Shield Coating®: The Most Durable Wall Coating for Cedar Siding
When Luis began researching longest lasting paint for cedar siding, he met with several exterior painting companies in the Chicagoland area, many of which are no longer in business. He chose Home Shield Coating® due to our reputation as the leading permanent coating provider in the country. Recognizing the long-term benefits, he appreciated that Home Shield Coating® offered a solution that would save money and reduce maintenance over the next 30 years.
Home Shield Coating®: A Money-Saving Paint Alternative for Cedar Siding
According to Luis, applying Home Shield Coating® to his cedar-sided home has saved him the equivalent of six paint cycles and thousands of dollars in cedar siding repairs. The only issue he encountered in over two decades of protection was a roof leak that led to some wood rot. He understood that wood rot is not covered under our warranty because if water gets behind unprotected cedar siding, it will cause damage over time.
Home Shield Coating®: Designed to Last Decades
After repairing the roof and replacing the rotting wood, Luis contacted us to purchase a gallon of Home Shield Coating® for the newly replaced sections. However, we informed him that we wouldn’t sell him the product but would instead perform the touch-up work for him. He was delighted that, despite the labor portion of his warranty having expired, we would help him maintain his home’s protection.
The Longest Lasting Choice for Cedar Siding in Chicago & Wisconsin
Luis’s home is one of hundreds we’ve coated across the two markets where cedar siding is most punished by weather. Chicagoland and Wisconsin homeowners share the same underlying problem — freeze-thaw cycles, wind-driven moisture off the Great Lakes, and cedar’s natural tendency to move — and both regions need a coating engineered specifically for that abuse. Here is what 25 years of real-world data means for homeowners in each market.
Proven Performance Across Chicagoland’s Toughest Suburbs
Cedar siding in the Chicago metro takes a beating no other region can match — lake-effect humidity in summer, sub-zero freeze-thaw cycles in winter, and wind-driven rain from Lake Michigan the rest of the year. Whether your home is a historic cedar estate in Barrington Hills, a custom property in Long Grove where cedar-clad architecture dominates, a wooded lot in Lake Zurich, or a lakefront build in Wauconda, Home Shield Coating® delivers the same 25-year, no-repaint performance you just read about in Luis’s case study. Homeowners across North Barrington, Inverness, South Barrington, Kildeer, and Hawthorn Woods have chosen Home Shield Coating® as the longest-lasting alternative to repainting or restaining cedar siding every three to five years — the same permanent solution that saved Luis over $247,000 in avoided repaints.
The Ultimate Cedar Protection for Wisconsin’s Freeze-Thaw Climate
Wisconsin’s freeze-thaw cycles are among the harshest in the country — and cedar siding is especially vulnerable to the moisture intrusion, cupping, and paint failure they cause. From the historic lakeside homes in Lake Geneva and the custom estates of Mequon, to cedar properties across Waukesha County, Elm Grove, and Brookfield, and the Madison and Milwaukee metros, Home Shield Coating® is engineered to expand and contract with the wood while sealing out water — the exact failure mode that shortens the life of every conventional paint and stain in this climate. If you’re weighing a Wisconsin cedar siding restoration versus another round of paint or stain, the math from Luis’s Chicago lakefront experiment applies to your home too.

The math on what Luis avoided paying
If Luis had continued repainting on his previous five-year cycle instead of coating the home in 2000, he would have paid for a paint job in 2000, 2005, 2010, 2015, 2020, and again in 2025 — six paint cycles across 25 years.
Painting costs have not stood still since 2000. Labor rates, material prices, and cedar itself have all inflated substantially. Using U.S. Bureau of Labor Statistics Consumer Price Index data, each avoided cycle can be expressed in the year Luis would have paid it, and then rolled forward to today’s dollars.
Working from the range of quotes he was actually receiving in the late 1990s — $17,000 on the low end, $22,000 on the high end — the picture looks like this:
Cycle year | Cost that year ($17K base) | Cost that year ($22K base) |
2000 | $17,000 | $22,000 |
2005 | $19,280 | $24,950 |
2010 | $21,530 | $27,860 |
2015 | $23,400 | $30,280 |
2020 | $25,550 | $33,070 |
2025 | $31,290 | $40,490 |
Year-of-cycle total | ≈ $138,000 | ≈ $178,600 |
Total in 2026 dollars | ≈ $191,000 | ≈ $247,200 |
Read three ways:
- Nominal, no inflation (6 cycles at his original quote): $102,000 to $132,000
- Cost avoided in the year of each cycle: ≈ $138,000 to $178,600
- Cost avoided expressed in 2026 dollars: ≈ $191,000 to $247,200
A single 2000-era paint cycle in Luis’s price range works out to roughly $32,000 to $41,000 in today’s dollars on a home that size. He is on his original coating, purchased once.
What actually makes a coating last on cedar
Twenty-five years of field performance is not an accident. Four things have to be right, and if any one of them is missing, even the best coating will fail early.
- Color stable technology. Standard exterior paint chalks under UV because the acrylic binder that holds pigment to the wall breaks down under sunlight. Home Shield Coating® is loaded with ceramic microspheres that dramatically slow that UV breakdown, which is why the color and sheen hold for decades instead of years.
- Approximately 17× thicker than paint. Bridges hairline checks in cedar, resists impact, and gives moisture far less opportunity to migrate. Paint at 2–4 mils is a decorative skin. This is a membrane.
- A three-coat, prep-heavy application process. Pressure wash, mildewcide, a proprietary bonding primer for tannin bleed on cedar, urethane caulk at every seam, then two full topcoats sprayed and back-rolled to spec thickness. When any coating fails prematurely, prep is almost always the reason.
- Application by trained crews only. Home Shield Coating® is not sold at retail. Every gallon in the field has been applied by our own installers. That is the only reason a 30-year warranty is structurally offerable.
When a permanent coating is the right answer
Home Shield Coating® is the right decision when:
- The home is cedar, wood, stucco, or fiber cement in a climate that is hard on exterior finishes
- The owner plans to stay long enough that a second or third repaint would otherwise be required
- The prior repaint history has already made clear that traditional paint is not solving the problem
- The transferable warranty and the resale value it adds are meaningful to the owner
For a home the owner plans to sell within a couple of years, a good premium acrylic on properly prepped siding remains a reasonable choice. This is not a universal answer.
Frequently asked questions
How long does Home Shield Coating® last on cedar siding?
Luis’s Chicago home reached 25 years in 2025 on the original coating, on a wall facing Lake Michigan. Our warranty is a 30-year combined coverage including 10 years of labor. In the field, we have homes coated in the 1990s across Illinois and Wisconsin still holding their original color and film integrity.
Is Home Shield Coating® just thick paint?
No. Standard exterior paint is a 2–4 mil decorative acrylic film. Home Shield Coating® is a ceramic-loaded acrylic coating applied at approximately 17× that thickness. Different chemistry, different application, different lifespan.
Will Home Shield Coating® work on my cedar siding?
Cedar is one of our most-coated substrates. We have 25+ years of installations on cedar-sided homes across the Chicagoland area and Wisconsin. Fiber cement, wood, and stucco are also within scope.
What is the warranty?
Thirty years combined coverage, including ten years of labor. The warranty is transferable to a new owner.
Do you sell Home Shield Coating® for do-it-yourself application?
No. The product is only available applied by our trained crews. That is the only way we can back the warranty.
Can I visit a completed job to see the coating in person?
We share our long-term projects through video walk-arounds rather than drive-by address lists. The video on this page is one example. During an in-home consultation, we can review additional project videos with you.
