Customer Ratings of Top BRANDS in the 2025 America's Most Trusted Study
In the sphere of home improvement, caulk sealants play a pivotal yet often overlooked role. These essential substances act as protective barriers against moisture, air leaks, and pests, enhancing both functionality and aesthetics in a variety of spaces. From preventing water damage in bathrooms to improving energy efficiency, choosing the right caulk sealant is critical for homeowners. With features like mold resistance and flexibility, awareness of product selection has become increasingly important for lasting results.
The decision-making process goes beyond technical attributes; brand trust significantly influences consumer behavior. In a market filled with options, shoppers are inclined to select brands they recognize and have confidence in. Trust can arise from a brand’s longstanding reputation, positive customer feedback, or recommendations from peers. For both consumers and manufacturers, understanding how brand loyalty affects purchasing decisions is essential in this landscape.
To explore this connection, we will refer to insights from America’s Most Trusted® study. This survey provides a deeper understanding of consumer evaluations of various caulk sealant brands, uncovering the elements that foster trust and loyalty. Through this analysis, we aim to clarify the brand dynamics shaping consumer preferences in this niche market.
The 2025 America’s Most Trusted Study
Launched in 2011, the America’s Most Trusted® study was established to illuminate the intricate relationship between consumer trust and purchasing behavior. This annual investigation is pivotal for brands seeking to navigate the competitive landscape, recognizing that trust significantly influences business performance. As the definitive benchmark for brand trust, the study garners considerable attention each January when fresh findings are unveiled.
At its core, brand trust encapsulates the assurance customers feel regarding a brand’s ability to fulfill its promises. Cultivating a robust relationship with consumers is essential for fostering loyalty and encouraging repeat business. Brands that effectively nurture trust enhance customer confidence during transactions and boost the likelihood of positive word-of-mouth recommendations, leading to a more loyal customer base.
Lifestory Research undertakes this extensive study each year, executing over 75 product analyses and collecting insights from thousands of consumers about their experiences and perceptions of various brands. The study employs a meticulously validated metric known as the Net Trust Quotient Score (NTQS), which gauges consumers’ trust in different brands when making product choices.
Beyond simply ranking trustworthiness within a specific product category, the NTQS also evaluates how well a product meets consumer expectations relative to its competitors. This trust metric aims to furnish brands with consumer-driven insights, employing rigorous social and opinion science research methodologies that adhere to high standards of consumer research quality.
One key question the study seeks to answer is: which caulk and sealant brands do consumers trust the most? By asking participants to evaluate various brands within this product category, the America’s Most Trusted study aims to reveal the leading brands that resonate with consumer confidence.

Rating Methodology
What Is the America’s Most Trusted® Study?
The America’s Most Trusted® study focuses on evaluating brands that offer products or services to consumers in their homes, particularly in the residential new home industry. Instead of attempting to survey every brand, the study specifically targets the largest and most impactful brands in this sector.
How Does the Survey Work?
Conducted throughout the year, the America’s Most Trusted® survey aims to gather consumer opinions while minimizing biases that might arise from external events or trends. This year-long approach helps capture a more accurate snapshot of consumer sentiments.
Participants are surveyed based on specific criteria, such as whether they are actively considering a purchase in a relevant category—like buying a home, faucet, HVAC. Only those who express familiarity with a brand are invited to share their opinions on its trustworthiness, ensuring that the study reflects genuine consumer insights.
The Importance of Brand Awareness
An essential component of the study is brand awareness. Participants are first asked to identify brands they recognize. Only those who are familiar with a brand proceed to answer questions about it. This criterion ensures that only brands with sufficient public recognition are included in the final trust rankings.
Sampling Methodology
The study employs a non-probability sampling design, relying on online panels to recruit participants. Online panels are organizations that have an established relationship with consumers who agree to complete opinion surveys. Lifestory randomly ask consumers questions that identify consumers shopping for a specific product. Qualified consumers complete an online survey in which they are asked a set of questions about specific product brands.
The number of people completing a survey is referred to as the sample size. Each of the America’s Most Trusted studies seek to obtain a sample size that is large enough to be representative. The sample size is also designed to collect a large number of consumer opinions to minimize error and to assure the study results reflect the majority of consumers sentiment about a brand.
Calculating Trust Scores
At the heart of the America’s Most Trusted® study is the Net Trust Quotient Score. Participants evaluate brands based on their trustworthiness through a series of targeted questions. The responses are then categorized into three groups:
Advocates: Consumers who express strong trust in the brand.
Neutrals: Those who trust the brand but do not consider it superior to others.
Antagonists: Consumers with little to no trust in the brand.
These evaluations are quantified using a statistical method called a z-score, which standardizes the responses, allowing for easy comparison across brands. The results are ultimately transformed into T scores, which are more intuitive for understanding how each brand ranks relative to the mean score of all brands surveyed.
