Walk into any Home Depot or Lowe’s on a Saturday morning and you’ll still see the familiar scene: homeowners loading up on paint, grabbing light fixtures, and debating between mulch colors. But behind the scenes, something fundamental is shifting. Both retail giants are making billion-dollar bets on a very different customer: the professional contractor.
This isn’t a minor strategy tweak. It’s a full-scale pivot that’s reshaping the home improvement industry. With economic uncertainty squeezing DIY spending, Home Depot and Lowe’s are racing to capture the $450 billion professional construction market. Here’s what that means for contractors, homeowners, and the future of how we buy building materials.
The great shift: From weekend warriors to professional contractors
The pandemic created a home improvement boom that seemed like it would never end. Stuck at home with savings and stimulus checks, Americans poured money into renovations. Home Depot and Lowe’s rode that wave to record profits.
But the landscape has changed dramatically.
High mortgage rates have locked homeowners in place. Housing turnover has slowed to a crawl. And consumers who were once eager to tackle DIY projects are now spending their money on travel, dining out, and experiences outside the home. The nesting instinct has given way to the “revenge spending” mindset.
This shift has hit DIY-focused retailers hard. Both Home Depot and Lowe’s have seen sales soften as homeowners defer big discretionary projects. But there’s one segment that’s remained remarkably resilient: professional contractors.
Unlike DIY customers, who delay projects when budgets get tight, professional contractors maintain steady backlogs of work. Insurance-paid repairs, essential maintenance, and new construction continue regardless of economic headwinds. In fact, 75% of surveyed professional customers reported healthy job prospects in mid-2025, according to Lowe’s quarterly data.
That’s why both retailers are repositioning themselves. They’re not just stores for homeowners anymore. They’re becoming essential partners for the tradespeople who actually build and renovate America’s homes.
By the numbers: Why pros are worth the investment
The math behind this strategic shift is compelling.
At Home Depot, professional customers represent only about 10% of the total customer base. Yet they account for roughly half of all sales, approximately $75 billion annually. That’s an astonishing concentration of value from a relatively small customer segment.
Lowe’s has historically been more DIY-focused, with professional customers contributing 20-25% of sales. But that figure is climbing rapidly. By mid-2025, Lowe’s reported that pro segment revenue had grown to 40% of total revenue, up significantly from just a few years prior.
The difference shows up in per-store performance too. Home Depot generates approximately $24.2 million in pro sales per store, compared to $9.5 million at Lowe’s. That gap explains why Lowe’s sees such a significant growth opportunity in catching up to its larger rival.
Professional customers also deliver better margins. While DIY segment margins typically range from 25-28%, pro segment margins run 20-30% but with far greater purchase volume and consistency. Pros buy in bulk, purchase more frequently, and stick with suppliers who deliver reliability.
Perhaps most importantly, pro spending is less cyclical. When economic uncertainty hits, homeowners postpone kitchen renovations. But contractors still fix burst pipes, repair storm damage, and complete ongoing construction projects. That stability is invaluable in volatile markets.
The acquisition arms race: Billions spent on pro infrastructure
Nothing signals strategic priority quite like massive acquisitions. In the past two years, both retailers have spent billions to build out their professional capabilities.
Home Depot has been particularly aggressive. In 2024, the company completed its largest acquisition ever: an $18.25 billion purchase of SRS Distribution. SRS operates approximately 760 branches across 47 states, specializing in roofing, pool supplies, and landscaping products for professional contractors. The deal added an estimated $50 billion to Home Depot’s addressable market.
That wasn’t all. Home Depot also acquired GMS (Gypsum Management Supply) for $4.3 to $5.5 billion, depending on final valuation. GMS specializes in drywall, ceilings, and steel framing, categories that are staples for professional builders but rarely purchased by DIY customers.
Combined with the $8 billion HD Supply acquisition from 2020, Home Depot has built a distribution network that extends far beyond its retail stores.
Lowe’s has responded with its own major moves. The company acquired Artisan Design Group for $1.325 billion, adding 132 facilities and 3,200 installers focused on interior finishes. More significantly, Lowe’s is closing an $8.8 billion acquisition of Foundation Building Materials (FBM), which brings 370+ distribution centers and access to 40,000 new professional customers.
These aren’t just financial investments. They’re structural transformations. Both retailers are evolving from store-based retailers into hybrid retail-wholesale distributors with sophisticated logistics networks capable of delivering materials directly to job sites.
What pros get that DIYers don’t
So what exactly are professional contractors getting that regular customers don’t? Quite a bit, as it turns out.
Job-site delivery and logistics. Home Depot now operates 17 flatbed distribution centers (FDCs) capable of handling bulk orders and heavy equipment. These facilities store and load the kind of materials that travel on flatbed trailers: lumber, drywall, roofing materials, and heavy machinery. Lowe’s is building similar capabilities through its acquired distribution networks.
Trade credit programs. Perhaps the most significant difference is payment terms. Home Depot now offers trade credit to approximately 7,000 companies, with plans to expand to tens of thousands by the end of 2026. Instead of paying upfront with a credit card, contractors get 30 days to pay after products arrive. For large projects with long lead times, this cash flow flexibility is crucial.
Dedicated sales support. Home Depot has grown its professional sales rep team from 300 in 2022 to over 1,500 today. These reps understand complex projects, can coordinate multi-location deliveries, and help contractors navigate bulk pricing and inventory management.
Digital tools and AI. Both retailers are deploying technology designed specifically for professional workflows. Home Depot’s new AI Blueprint Takeoff Tool can analyze PDF construction plans and generate material quotes automatically. Lowe’s offers AI-powered estimating tools and the MyLo Companion app for project management.
Reserved inventory and flexible scheduling. Professional customers can reserve inventory for specific projects and modify delivery times when construction schedules shift. These capabilities matter enormously when coordinating complex jobs with multiple trades.
Loyalty programs with real benefits. Both retailers have enhanced their pro loyalty programs with perks like bulk pricing, priority service, and extended credit terms. Lowe’s Pro Extended Aisle platform provides real-time inventory visibility across the entire network.
What this means for DIY homeowners
If you’re a homeowner who occasionally tackles weekend projects, you might wonder how this shift affects you. The honest answer: it probably won’t change much in the near term, but there are some things to keep in mind.
First, the core retail experience isn’t going anywhere. DIY customers still represent 50-60% of sales at these retailers, and that business remains important. You’re not going to show up and find the store converted to a contractor-only warehouse.
However, you may notice some changes. Product selection might shift slightly toward professional-grade materials and away from entry-level DIY products. Store layouts could evolve to accommodate pro services and pickup areas. And during peak contractor hours (early mornings), you might find yourself competing for attention with builders placing large orders.
The bigger impact might be on pricing and availability. As retailers optimize for professional customers who buy in bulk, individual consumers may find that some products are only available in larger quantities or at different price points.
On the flip side, this shift could benefit homeowners in unexpected ways. As retailers build deeper relationships with professional contractors, they’re becoming better positioned to connect homeowners with reliable pros. The same infrastructure that delivers materials to job sites can help streamline your renovation project.
For repairs and small projects, DIY will always have a place. Not every task requires a contractor, and many homeowners genuinely enjoy hands-on work. But for larger projects, the growing divide between retail and professional supply chains might make hiring a pro more attractive, simply because they’ll have access to better pricing, delivery, and support.
The future of home improvement retail
This isn’t a temporary pivot. It’s a fundamental reset of how home improvement retail works.
The big-box chains are transforming themselves into something new: hybrid retail-wholesale distributors that can serve both individual consumers and professional builders at scale. They’re embedding themselves deeper into the construction supply chain, offering not just products but logistics, financing, and digital tools.
For smaller competitors, this creates both challenges and opportunities. Independent hardware stores, regional distributors, and specialty suppliers can’t match the scale or technology investments of Home Depot and Lowe’s. But they can compete on local knowledge, specialized expertise, and personal relationships. The key is understanding which customer segments they can serve better than the giants.
As housing market conditions eventually normalize, both retailers will likely maintain their pro focus. The investments in distribution networks, digital tools, and credit programs create competitive moats that are difficult to replicate. And the economics of professional customers, with their higher ticket sizes and recurring purchases, are simply too attractive to ignore.
The real question is what happens to the DIY market over the long term. Will younger generations, facing high home prices and different lifestyle priorities, embrace home improvement with the same enthusiasm as previous generations? Or will the professionalization of home services continue, with more homeowners choosing to hire contractors rather than tackle projects themselves?
For now, one thing is clear: the home improvement industry has shifted its focus from weekend warriors to professional contractors. And that shift is reshaping everything from store operations to supply chains to the customer experience.
