The global demand for lumber has skyrocketed since the world went into lockdown. Consider this stat: Lumber prices have risen by 130% since before the COVID-19 pandemic, which makes for an estimated $24,000 difference in the cost of a newly constructed single-family home, per data from the National Association of Home Builders.As of press time, the average lumber price is $1,372 per 1,000 board feet.Accordingly, lumber futures have increased an astounding 375 percent between April 2020 and April 2021, Forbes reports. That basically means investors have sunk almost four times as much money into the same exact amount of wood compared to a year ago, because the spike shows no signs of stopping."The price of physical lumber seems like it still has to rise a bit more because mills are at capacity and unable to meet current demand," commodities expert Sal Gilbertie writes at Forbes. "Price rationing is really the only solution, and lumber prices have clearly begun the painful process of finding the highest price above which few people, be they professionals or DIYers, will pay."Why is lumber so expensive right now?How did we get here? You can blame a few factors. For starters, construction of new homes has steadily risen for the last few years, even before the pandemic. As wealth increases around the world, lumber demand increases with it, because lumber is a totally fungible good that translates into virtually every economic situation worldwide. Second, think about your own pandemic behavior. Chances are you spent the last year at home trying to tackle new (or long-promised) DIY projects for your backyard, like, say, a pergola. Naturally, the pandemic has increased consumer demand for lumber for such projects. Ditto for restaurants, which also had to build an unprecedented amount of outdoor seating spaces to comply with COVID-19 regulations. "Businesses are beginning to face the challenge of producing adequate supplies of goods and services—whether of lumber or of cold beer — to satiate that resurgent demand," the New York Times reports. "After huge disruptions over the last year, the intricate networks by which major industries keep shelves full and services available have become frayed."This is a key part of the pandemic narrative around the world. Every industry relies on a supply chain, and many of these have been disrupted or even wrecked in the last year. That’s on top of regular shortages like steel and battery materials, unrelated to the pandemic, that occur in every industry from time to time. It’s a perfect storm of high demand and low infrastructural capacity.What can you do?If the price of lumber could keep rising without any sensible limit, where does that leave backyard builders like you?"For small projects, you’re simply better off buying lumber than trying to substitute your labor for various workarounds," says Pop Mech’s senior home editor Roy Berendsohn. But if that just isn’t an option, you can follow a few backup strategies:Strategy #1: Use reclaimed lumber."If you know a remodeler, ask them if they have a demolition project on their calendar," Berendsohn says. "Or if you know somebody who is planning a remodeling job, see if you can handle some portion of the demo work in return for the lumber."You might even reclaim some lumber from your own underused furnishings. "Are there old attic or basement shelves that can be repurposed? Is there an old bookcase that can be cut apart and repurposed?" Consider being a little more careful than normal and reuse the valuable scrap, Berendsohn recommends.Strategy #2: Use wooden pallets.Pallets have a special disincentive for most kinds of recycling because they’re made of both hard and soft wood. "Many times, disposing of pallets poses such a nuisance to a company that they may be yours for the asking," Berendsohn says. From there, you can break or cut them up into whatever materials you need.Strategy #3: Consider alternative materials.This is more of an ideological choice than one that will save you money, Berendsohn admits. But if you want to use less lumber, or you’re just tired of looking at the empty racks at your local home repair goods superstore, consider reframing your project—literally."Will some small concrete blocks substitute for that lumber you were going to use for that raised garden bed?" says Berendsohn. "Maybe rocks for the raised bed?"Strategy #4: Avoid wasting lumber.This is key. If all you can grab is a single sheet of plywood, plan your project carefully so you cut just what you need in the shapes you need, Berendson advises. But it goes further than that. Think about stock lumber sizes and plan to use whole cuts or as close as you can get. You might have to do some math, but you won’t end up needing to cut and use six inches from an entire 2x4. In the same vein, consider checking with the lumber department at your local home repair superstore. The staff will likely have some offcuts you can use, rather than just buying whole new stock cuts.
