My house has been used for some unusual things in it’s 140 years of life, which I know explain some of it’s oddities.
-Someone glued green linoleum to the hardwood floors in every single room in the house (including the stairs). Later this was covered with carpet, tile, and in some places, another layer of hardwood.
-They painted over oil paint with latex paint and no primer, causing the paint to fail and flake off in sheets down to the bare wood. On the exterior of the house.
-They painted everything with the same flat white wall paint (applied by a sprayer, we can tell by stains on the linoleum). Oak doors and old-growth redwood trim.
-The water heater was connected to it’s vent by six inches of tinfoil and duct tape.
-They took off all the downspouts for the gutters, and took them away.
-The flagstone patio they installed sloped towards the house. Specifically, it’s graded like a pitcher nozzle, to direct all water to the corner where the back porch meets the house, where it can sit in a giant puddle for weeks before seeping into the foundation.
-“Some dampness in the basement” is not 4 inches of standing water at every rainstorm, requiring french drains installed around the house, drains through the yard, and two sump pumps. The stonework they installed in the front of the house was done in such a way that turned the front yard into a “bathtub” according to our contractor. Our grass was like a swamp.
