Introduction
In April 2025, the US garage door market experienced a remarkable phenomenon – a uniform 6% price increase across all major manufacturers within a two-week period. This synchronized price movement has raised eyebrows among industry observers and consumers alike, particularly as it comes on the heels of increased tariffs on imports from China, Mexico, and Canada. While external factors like tariffs and rising material costs provide a plausible explanation, the coordinated timing and identical percentage increase across competitors suggest potential oligopolistic behavior in the market. This article examines the various factors at play and explores whether this price movement reflects regular market forces or points to potential anti-competitive practices.
The landscape of the garage door market in the United States
The garage door market in the US is significant. According to Focus Reports, it is estimated to be valued at around $3.36 billion in 2023 and is projected to reach $4.18 billion by 2029 at a CAGR of 3.7%. North America dominates the global garage door market, with 58.02% of the global market share as of 2021 Fortune Business Insights.
The market is characterized by a limited number of dominant players, among which three manufacturers stand out:
- Clopay: Owned by Griffon Corporation, Clopay is considered the largest manufacturer of residential garage doors in the US.
- Amarr: Acquired by ASSA ABLOY, a global leader in access solutions, Amarr is another major player in the US market.
- C.H.I. Overhead Doors: In 2022, steel manufacturer Nucor Corporation acquired these (previously owned by KKR, a private equity firm).
- Wayne Dalton is one of the leading manufacturers of residential and commercial garage doors in the United States. Founded in 1954, the company has built a reputation for producing high-quality garage doors.
Together, these companies form the backbone of the “big four” in the garaUS ge door manufacturing sector. Although other players are in the market, these four companies maintain a significant market share and influence industry trends.
Price increases in April 2025: Timing and uniformity
In April 2025, all three major manufacturers – Clopay, Amarr, and C.H.I. Overhead Doors – increased prices by 6% over two weeks. Wayne Dalton increased by 5%. This timing is particularly notable for several reasons:
- Virtually Identical Percentage: All four companies implemented the same percentage increase despite being competitors.
- Synchronized timing: The price increases occurred in a narrow two-week window in April 2025, suggesting possible coordination.
- No pre-announcement: The price increase occurred with minimal warning to distributors and consumers, limiting the ability of customers to stock up before the price increase.
- Working in the garage door industry, I’ve found it surprising that manufacturers and suppliers who sell their garage doors consistently maintain nearly identical pricing. No matter what happens, even for non-insulated doors of the same size, the price differences are minimal, often around $70. For insulated doors, the difference might be closer to $100. It has always been this way.
- If we look at the dates, it’s clear that the recent price changes began in April 2025. C.H.I. changed their pricing on April 15, while Amarr did it slightly earlier, on April 12, both increasing prices by the same percentage: 6%. Other major companies also raised their prices throughout April.
External factors leading to price increases
Several external factors are cited to justify the price increase:
1. Tariff increases
The Trump administration imposed significant tariff increases in early 2025: “Until the crisis is abated, President Donald J. Trump is imposing additional tariffs of 25% on imports from Canada and Mexico and additional tariffs of 10% on imports from China ”. These tariffs went into effect in March 2025 and have since been lifted temporarily and not on all items.
Garage door manufacturers rely heavily on imported materials, especially steel and aluminum. According to industry reports: “In just two weeks following the tariff change, garage door prices increased by 6-20%, depending on the model and materials used”.
2. Rising material costs
Steel is the primary material used to make garage doors, and its price is volatile:
- Nucor, which now owns C.H.I. Overhead Doors has implemented several steel price increases in 2025, with hot-rolled coil prices rising to $930 per short ton by March 17, 2025, Steel Industry News.
- This represents a “staggering 35.6% increase in steel prices since July” Steel Industry News.
3. Supply chain pressures
Continued global supply chain issues have impacted manufacturing across all industries, with garage door companies citing increased shipping costs and lead times as influencing pricing decisions.
The Oligopoly Question: Analyzing Market Structure
While external factors provide a plausible explanation for price increases in general, the uniformity and timing of the 6% increase raise questions about the garage door industry’s competitive dynamics.
Characteristics of oligopoly
An oligopoly is a market structure characterized by:
- A small number of dominant firms
- High barriers to entry
- Interdependent pricing decisions
- Potential for tacit collusion without explicit agreements.
The U.S. garage door industry exhibits several of these characteristics:
- Market Concentration: A few players dominate the industry, with Clopay, Amarr, and C.H.I. controlling a significant portion of the market.
- Barriers to Market Entry: Garage door manufacturing requires significant capital investment, a developed distribution network, and brand recognition, which creates high barriers to market entry.
- Price following behavior: When one manufacturer changes prices, others quickly follow suit.
- The fact that nearly identical doors of the same size are priced almost the same across different brands is quite surprising and naturally raises questions and doubts about the situation.

Oligopolistic behavior
Several factors suggest that the April 2025 price increase may reflect oligopolistic coordination rather than an independent response by competitors:
- Same percentage: Despite different cost structures and supply chains, all major producers set the price at exactly 5 – 6%.
- Timing: The two-week implementation window suggests possible signaling or tracking behavior.
- Market power: With limited competition and high barriers to entry, the “big four” producers can implement price increases with minimal risk of losing market share.
- Vertical Integration: Nucor’s ownership of C.H.I. creates a vertically integrated structure that has the potential to influence pricing in the industry because Nucor supplies steel to several garage door manufacturers.

| Manufacturer | Model | List Price* | Key Features | Material | Warranty |
|---|---|---|---|---|---|
| Clopay | Classic Steel Short Panel (Model 4050) | $1,299 | 24-gauge galvanized steel, short panel design, rugged track and hardware | Steel with reinforced panels | Limited lifetime warranty on steel sections |
| C.H.I. Overhead Doors | Raised Panel 2250 | $1,249 | 25-gauge steel, short panel design, heavy-duty hardware | Hot-dipped galvanized steel | 10-year limited warranty on sections |
| Wayne Dalton | Classic Steel Model 8000 | $1,179 | 24-gauge steel, pinch-resistant panels, TorqueMaster® spring system | Embossed steel | Limited lifetime warranty on sections |
| Amarr | Lincoln LI1000 | $1,225 | 25-gauge steel, short panel design, corrosion-resistant hardware | Steel with reinforced stiles | 15-year limited warranty on sections |
*Prices are for the door only, without installation, and may vary by region and dealer. Average installation costs range from $250-$500 depending on location and complexity.
Of course, these doors are not completely identical — slight differences exist. For example, Clopay’s Model 4050 is arguably better in quality than Wayne Dalton’s Model 8000, yet the price difference is over $100. If you look closely, you won’t find a door priced at $900 or above $1,600. Instead, we see nearly identical pricing across the board. So what does that tell us?

- 2022-2024: Price increases aligned with industry trends due to material costs and supply chain issues
Industry Context:
The dramatic price increases during 2020-2021 were primarily driven by:
- Steel price increases (up 91% since the end of 2020) [Gordian]
- Supply chain disruptions during and after the COVID-19 pandemic
- High demand for housing and home improvement projects
The more modest increases in 2022-2024 reflected stabilizing supply chains and gradual normalization of material costs, though prices remained significantly higher than pre-2020 levels.
According to industry reports, garage door prices have increased between 39.9% and 74.9% from 2020 to 2024, depending on the manufacturer, with most companies implementing their most significant price increases in 2021.
Summary Analysis of Garage Door Price Increases (2020–2024)
As a result, we can see that prices have changed differently across brands. Unfortunately, they rose sharply during the COVID period and continued to increase year by year. We also observe a significant difference in price hikes between Clopay and Wayne Dalton brands. This leads us to conclude that a market-driven economy still exists, and while there may be some elements of oligopoly, they appear to be partial and seasonal.
Alternative explanations
While oligopolistic behavior is a plausible explanation, other factors may also explain the uniform price increases:
- Similar cost structure: Large producers may be subject to similar costs and tariffs, resulting in comparable price adjustments.
- Industry Standards: Garage door pricing may follow industry standards that naturally lead to similar price changes.
- Legitimate cost response: The 6% increase may reflect the impact of tariffs and material cost increases on manufacturers’ margins.
Consumer and Market Implications
The 6% price increase has several implications:
- Consumer Impact: Homeowners will face higher garage door replacement and installation costs, with the average cost of a standard garage door installation rising from about $1,500 to $1,590. Let’s not forget that a price increase already occurred in March, which was also linked to the impact of tariffs.
- Market Efficiency: If the price increase reflects oligopolistic coordination rather than competitive forces, it represents a market inefficiency that could be detrimental to consumer welfare.
- Policy Considerations: This case highlights the potential need for antitrust oversight in concentrated industries where price coordination may occur without explicit collusion.
Conclusion: Coincidence or coordination?
The findings present a mixed picture. All major garage door manufacturers increased prices by 6% in April 2025, along with legitimate external pressures from tariffs and rising material costs. The similar timing and percentage of price changes among competitors in a highly concentrated industry with barriers to entry raises the question of possible oligopolistic coordination.
Determining whether this price change is an independent decision or a result of hidden coordination requires reviewing the company’s internal communications and cost structure. The U.S. garage door industry exhibits typical features of a seasonal oligopoly, as its pricing strategies are interdependent, and firms often outpace or follow market prices. Our analysis of price increases between 2020 and 2024 demonstrates a functioning market economy that benefits the industry.
Our analysis excluded companies such as Haas Door, Pro Door, and Raynor, which increased their prices by 5-8%. By keeping their product prices stable, Invicta is poised to increase sales in the future.
Consumers are seeing a direct effect, as garage doors now cost more everywhere. This example gives policymakers and market observers insight into the dynamics of a concentrated industry where competitive response and coordinated pricing look the same for tariff-induced price changes.
FAQ
What is an oligopoly in simple words?
An oligopoly is a market structure where a small number of large companies control most of the market. Unlike a monopoly (where one company dominates) or perfect competition (where many small companies compete), in an oligopoly, only a few powerful firms make most of the sales and significantly influence prices and industry practices.
What are examples of oligopolies?
- Telecommunications: AT&T, Verizon, T-Mobile (in the US)
- Smartphones: Apple and Samsung dominate the high-end market
- Commercial aviation: American Airlines, Delta, United, Southwest (in the US)
- Soft drinks: Coca-Cola and PepsiCo control most of the market
- Credit cards: Visa, Mastercard, American Express
- Social media: Meta (Facebook, Instagram), TikTok, Twitter/X, Snapchat
- Video game consoles: Sony PlayStation, Microsoft Xbox, Nintendo
- Oil and gas: ExxonMobil, Chevron, BP, Shell
- Breakfast cereals: Kellogg’s, General Mills, Post
- Media and entertainment: Disney, Warner Bros. Discovery, Universal, Paramount
Why are oligopolies often considered problematic?
Oligopolies can have several negative effects on markets and consumers:
- Higher prices: With limited competition, firms can maintain prices above truly competitive levels, reducing consumer surplus
- Price coordination: Companies may engage in tacit collusion or “price leadership” where they follow each other’s price changes
- Reduced innovation: With less competitive pressure, firms might invest less in research and development
- Barriers to entry: New competitors face significant challenges entering the market
- Economic inefficiency: Oligopolies often produce at higher costs and lower quantities than what would be socially optimal
- Market power abuse: Dominant firms can potentially engage in anti-competitive practices
- Wealth concentration: Profits tend to accumulate with a small number of large corporations
Can garage door prices increase even further?
Yes. Tariffs are currently suspended at 145%, and I can tell you that most garage door hardware parts come from China. So we’ll have to wait for further news regarding tariffs related explicitly to imports from China.
What would happen economically if garage door prices decreased?
As long as there’s strong demand for garage doors, all manufacturers will naturally try to keep producing and selling at current levels. However, if the market takes a downturn or garage doors become so expensive that most homeowners can no longer afford replacements, the market will shift in the opposite direction, and prices may fall. If prices begin to drop, it will give us a clearer picture of whether there’s actual oligopoly behavior in this industry.
Are prices increasing for all types of garage doors?
Yes, prices are rising, depending on the materials used. Garage doors are primarily made of aluminum and steel, which have significantly increased in cost as raw materials.
Will garage door prices continue to rise in 2025?
Of course, prices may continue to rise — especially if the tariffs that have already been introduced and temporarily delayed go into full effect. We may also see price increases on garage door hardware since nearly all components are imported from China, where the tariff rate has already reached 145%. That’s why we should expect further increases in garage door prices across the U.S. market.
Does Firstline Garage Door Repair offer affordable options despite the increase?
Yes. We work directly with suppliers to provide competitive pricing, seasonal discounts, and custom packages to help homeowners get the best value.
Could this be considered price fixing or illegal?
While not proven illegal, the synchronized timing and identical percentages raise concerns about possible oligopolistic behavior rather than open-market competition.
Why are prices nearly the same across all major garage door brands?
The industry is dominated by a few large manufacturers, and their pricing tends to follow each other closely — a common sign of an oligopoly. If you look at the price chart, you’ll be surprised that the prices for the same type of garage doors — identical size, insulation, color, material, and add-ons — do not differ much across manufacturers. The difference is usually around $100, which is very suspicious.
