Home improvement stocks generally represent retailers selling products and services to homeowners and contractors. Building materials stocks more often represent companies that manufacture, distribute, or install the materials and components used in construction and remodeling. The categories overlap: Home Depot sells building materials, while Builders FirstSource serves both new home construction and repair and remodeling.
How the two categories differ
The simplest distinction is where a company sits in the home-improvement supply chain. A retailer assembles a broad assortment of products and sells it to customers; a building-products company may make, distribute, or install particular inputs. But “building materials stocks” is a broad label, not one uniform business model.
| Comparison | Home improvement retailer | Building materials company |
|---|---|---|
| Typical activity | Retail sales, often with installation, rental, or other services | Manufacturing, distribution, installation, or a combination |
| Typical offering | A broad assortment of home-improvement products and related goods | Specialized materials, components, or products such as structural products or coatings |
| Potential customers | DIY consumers, professional contractors, or both | Homebuilders, professional contractors, industrial buyers, commercial customers, or retail customers, depending on the company |
| Category boundary | Can sell building materials as part of a larger assortment | Can serve remodeling as well as new construction |
These are broad descriptions, not strict industry boundaries. For example, Home Depot describes a retail business spanning home-improvement products, building materials, lawn and garden goods, décor, and facilities-maintenance items. It also offers installation and tool and equipment rental. Home Depot’s fiscal 2025 annual report describes that mix.
Company examples show why the labels are not interchangeable
Home Depot: broad retail assortment and services
The Home Depot (NYSE: HD) is a retail example: it sells across multiple home and maintenance categories and adds services such as installation and equipment rental. Its fiscal 2025 investor documents report $164.7 billion in net sales and $14.2 billion in earnings. Those are company-reported fiscal-year figures, not measures of the home-improvement stock category as a whole. See Home Depot’s investor documents.
Lowe’s: another retailer to assess from its filing
Lowe’s (NYSE: LOW) is another major home improvement retailer. Its fiscal 2025 Form 10-K covers the year ended January 30, 2026; use the filing’s business description and disclosures when assessing its specific activities and exposures rather than assuming every retailer has the same mix. Read Lowe’s fiscal 2025 Form 10-K.
Builders FirstSource: manufacturing, supply, and installation
Builders FirstSource (NYSE: BLDR) manufactures, supplies, and installs structural and related building products for professional builders. Its markets include new residential construction and repair and remodeling. The company reported approximately 585 locations in 43 U.S. states in its 2025 Form 10-K; that is a company-reported footprint, not a measure of its addressable market. See the 2025 Form 10-K.
Rank #2
Sherwin-Williams: a materials maker with a different product mix
Sherwin-Williams (NYSE: SHW) develops, manufactures, distributes, and sells paints, coatings, and related products. Its customers include professional, industrial, commercial, and retail buyers. That makes it a building-materials example, but its products and customer mix differ from a structural-products supplier such as Builders FirstSource. Sherwin-Williams’ investor relations site provides its company overview.
What investors should compare company by company
A category name alone does not tell you how a stock is exposed to construction or remodeling. For each company, examine the same factors in its own filings and investor materials:

- Activity: Identify whether revenue comes from retailing, manufacturing, distribution, installation, or a combination.
- End market: Look for exposure to new residential construction, repair and remodeling, nonresidential construction, industrial use, or multiple markets.
- Product mix: Distinguish a broad store assortment from specialized materials, components, or coatings.
- Demand and costs: Review company disclosures about demand drivers and input costs. Housing activity and cost exposure can vary materially by product and customer.
- Financial measures: Compare matching fiscal periods and consistent definitions for sales growth, margins, cash flow, debt, capital returns, valuation, and dividends.
As one period-specific example—not a realized result—Builders FirstSource’s 2025 Form 10-K cites a Home Improvement Research Institute forecast, issued in September 2025, for a 2.9% increase in professional repair-and-remodel end-market sales in 2026 compared with 2025. The figure is a forecast with that source and date, not a company-wide growth rate or a result for 2026. The filing contains the attribution.

The labels help distinguish companies that sell finished assortments and services from companies that make, distribute, or install construction inputs. Both types can be affected by housing and renovation conditions, but the degree and direction of exposure depend on each company’s customers, products, costs, geography, and operating model.
Business descriptions alone do not establish which category is safer, cheaper, or more likely to outperform. The figures above do not provide a comparable valuation, dividend yield, return, or expected-growth ranking across the companies. Those comparisons require current, consistently defined financial and market data.
