Unfinished basements offer a treasure trove of curiosities. What we love most about basements—the old-fashioned, spider-filled kind—is the hints to the history of the home. The older the basement, the weirder it will be, with tiny trinkets left in corners from past owners, structural updates, repaired damages, and clues about the heating system before this one. Basements allow us to solve the mysteries of a home, whether that’s deducing the choices a previous owner made about the house, or deciding on the next set of choices to fix an issue down the line.

Finished basements, meanwhile, are almost like the original house hack. They add a good deal of square footage to serve as living space, all within the envelope of an existing home. The only downside as a buyer or homeowner is that putting up walls doesn’t allow you to see what’s happening behind them, with systems like plumbing and wiring hidden away. Even issues from upstairs, like a leaking dishwasher, will become visible in the basement eventually. But it will be apparent sooner if finished ceilings aren’t obstructing the view.

Of all of the normal and not-so-normal basements we have toured, a few wacky favorites come to mind for us:

• - There was a house that had an actual live water main break in the basement during the showing, just pooling in the corner like a koi pond with no one seeming to care
• - The in-ground-swimming-pool-turned-basement
• - The investment property where decades of improper drainage and neglect had left visible daylight between the blocks of the foundation walls
• - The pre-Revolution colonial that sloped in multiple directions; it was held up in one corner with a bundle of cardboard! 

Basements, even if you can’t recognize their beauty, need to be cared for.   

Don’t ignore your basement! Whether the space is finished or not, whether it feels ‘scary’ or not, you need to be there periodically to keep tabs on your systems and structure. You can tell a lot about the health of your house by the condition of a basement. And the condition of your basement has plenty to do with moisture.  

Managing moisture will keep masonry (foundations, brickwork) solid, wood structure (sill plates, main beams, floor joists) dry and less inviting to insects, and flooding to a minimum. The easiest, cheapest first step anyone can take to reduce basement moisture is to install extenders on all gutter downspouts—get water away from your foundation, and things can only improve.  A dehumidifier doesn’t hurt either. We recommend finding a model you can drain through a laundry sink or basement drain so you don’t have to empty it.
