I've repeatedly complained to the builder, sometimes loudly. The builder had 4 large deep holes dug behind the house looking for water, they were dry. He had holes bored into the lowest part of the foundation hoping trapped water would flow out but that was dry too. The builder says that he's out of ideas and at this point says that it's our problem and our responsibility because he built the house on land that we purchased separately, ergo that's our water and not his so it's not his responsibility. The builder says that his preferred flooring company can take care of this, they'll move all of our furniture, peel up all of the vinyl floor planks to expose the slab, coat the slab with chemical goo sealant, put the floor back down and move our furniture back. Cost to us: $21,000, plus tax. I've had all the plumbing tested, the house independently inspected, I've talked to a lawyer, a hydrologist and various consultants, all not cheap.
I've also talked to local people in the building trades and have slowly come to learn that we are not alone, I've heard a few stories of people all over town with similarly afflicted houses, some new and some old, that have lost very expensive natural hardwood floors to discoloration and warping or had elaborately decorated floor tiles pop up and have their unique hand painted decorations on their floors ruined. Our vinyl planks are basically durable plastic fake wood and won't be harmed by exposure to moisture. What's happened to our house and others seems to be the direct result of the unprecedented record smashing wet winter we had last year. People who have lived here all their lives have told me they never saw anything like winter 2022-2023, it was one for the record books, it was wet winter without end. Water is trapped in the ground all over this part of the state and is slowly percolating up and being released as water vapor. The house is heavily insulated and sealed per code so the water vapor that comes up through the concrete slab has nowhere to go and accumulates in the house.
What to do?
- Improve drainage (swale work already in progress)
- Cross our fingers, do nothing and get on with our lives with the hope that weather patterns and precipitation amounts return to historical norms. Summer is the rainy season here and rainfall was below normal. Still, a long term drought starting right now would be most helpful.
- Have our lives disrupted and pull up the vinyl planks and seal the top of the slab with chemical goo sealant for $21,000+ as suggested by the builder and hope that it fixes the problem and doesn't cause new ones.
- I've purchased some humidity sensors and can remotely monitor moisture levels in the air inside the house and garage and open windows and doors as needed as weather permits.
Unless derailed by something else new and out of the blue the plan now is to get on with our lives. We've been preoccupied and grounded by a succession of Covid fears, construction and new house problems for almost 4 years now and it's time to put all of that aside and bust out. We're getting old, the travel window for us will soon close whether we like it or not. Because the time is now.
