Updated May 3, 2021, to add more insight from Robinson Meyer (The Atlantic) as to why lumber prices are so high.

My architect and I are still working on plans, slowly but surely. Read my previous entry, Two-flat journal #4, to understand why that seems to be taking awhile.

There is something else on my mind as we work toward the goal of a gut-rehabbed two-flat: How much this whole project is going to cost.

I’ve talked to several contractors, engaged a structural engineer to specify and design the new steel beam in the basement, and obtained quotes for all new windows from four manufacturers.

One contractor happily gave me an estimate, based on incomplete plans, that was about $220,000. That price could go down with more specific plans and instructions, as the estimate had variability based on unknowns, and it doesn’t include the cost of purchasing the windows. More likely, I think the price will go up due to material costs.

How much windows might cost

All window quotes I’ve obtained include installation by the manufacturer’s selected installers, which has a benefit from some companies, mainly that the maker will guarantee the installation for a period of time.

The first floor living room window is currently double hung with a mullion and a tripartite transom window above it (with stained glass, that’s been covered on the inside). This window will become a “Chicago window” with a centered picture window flanked by casement windows.

I would share the quotes with you but I don’t think they would be very helpful at this point because I haven’t evaluated each of the quotes on the quality of the window. For example, one of the window quotes was three times higher than the next highest quote, but the maker guarantees installation for 10 years and is a higher-quality window. But what is the factor of difference in quality, is it three times? And how valuable is a 10-year installation warranty? It’s unlikely I would need to avail that benefit and the three times difference in price means I could replace all of the windows *again* two times for the same price! (Assuming prices didn’t increase between now and that future moment.)

The 15 new windows, according to the four quotes, will cost anywhere from $12,000 to $46,000. I should mention that the highest quote doesn’t include any discounts or special offers, as those will be offered once I re-engage the estimator and ask for one.

Look at windows 1.1 and 1.3, which look like bay windows. These are both Chicago windows, which have a center picture (fixed) window flanked by two operable windows (casement windows, in this case).

There are a couple of opportunities to reduce window costs. I could convert more of the casement windows to be double hung windows (which I don’t want to do as I prefer single hung windows), or I could change the window opening size. A couple of the window openings are taller than most of the window makers have in their standard window design, so an upper transom (fixed) window would be required. However, changing the window opening size may end up shifting costs to a different plan of adding bricks and adjusting walls.

Another way to reduce the window cost would be to use models that are less energy efficient, but I also don’t want to do that. I’ve insisted that every window be Energy Star certified – this is about the only certification standard that I understand, and it’s common across most window makers in the Chicago area. (There are also Passive House and Passivhaus certified windows, and companies that import higher-quality and more efficient windows from European manufacturers, but I haven’t bothered with any of those because I assume the prices will be even higher.)

Lumber and other construction materials

That lumber prices have more than doubled over prices a year ago is well known if you read real estate industry news media, or if you’ve shopped for wood at Menards to build a couple of benches for some nicer outdoor space or installed a new porch.

My gut rehab will require a lot of plywood (to replace the subfloor), “soft lumber” replacement studs, and some replacement joists.

The St. Louis Federal Reserve maintains “FRED”, an amazing website with interactive charts to explore economics statistics, including lumber. The pricing information comes from the Bureau of Labor Statistics and their Producer Price Indexes.

The chart for the plywood price index below shows very stable pricing in fall and winter 2019-2020, and then in May 2020 prices start climbing and the index increased by 100 points to March 2021.

BLS has monthly detailed reports so you can find data about more than the products FRED has charts for. Let’s dig in to the March 2021 report (indexes mean that the pricing represents percentage changes based on 100% being the price when the index was established):

  • “Softwood dressed 2-inch lumber, 2 inches in nominal thickness only, not edge worked” (a.k.a. 2×4 studs) (index established June 2012):
    • March 2020: 205.1
    • March 2021: 324.1 (this means that the price has increased by 119% year over year, a more than doubling of price)
  • “Softwood plywood products: rough, sanded, and specialties” (index established December 2011):
    • March 2020: 139.0
    • March 2021: 242.9 (again, this means that the price has increased by 103.9%, doubling the price)

In addition to general demand being much higher, there are other reasons why lumber costs so much more right now, according to Robinson Meyer writing in The Atlantic last week.

Since 2018, a one-two punch of environmental harms worsened by climate change has devastated the lumber industry in Canada, the largest lumber exporter to the United States. A catastrophic and multi-decade outbreak of bark-eating beetles, followed by a series of historic wildfire seasons, have led to lasting economic damage in British Columbia, a crucial lumber-providing province. Americans have, in effect, made a mad dash for lumber at the exact moment Canada is least able to supply it.

“There are people who say, ‘Climate change isn’t affecting me,’” Janice Cooke, a forest-industry veteran and biology professor at the University of Alberta, told me. “But they’re going to go to the hardware store and say, ‘Holy cow, the price of lumber has gone up.’”

It has lost 2.5 billion board feet of annual production capacity since 2019, enough to shift prices in a North American market of 70 billion annual board feet, Jalbert said.

Read Robinson’s full article to see how the bark-eating beetles overwhelmed the forests of British Columbia and the northern forest belt in Canada and why their rampage is fueled by climate change.


The same contractor, when they checked in with me recently, said that the prices of other construction materials had gone up, too.

In the same Producer Price Index report, it looks like wood doors and door frames went up 29.2% from March 2020 to March 2021; metal windows are up 7.1%, double hung wood windows are up 6.8% and wood casement windows are up 5.1%; wood moldings are up 16.9%.

I didn’t see any notable price increases in plumbing materials or kitchen cabinets – all were close to inflation. The PPI doesn’t have vinyl window products, or I don’t know under which category it falls.
