I'll try to make a long story short. My home was built in 1952. I bought it 3.5 years ago. I plan on moving in 3-4 months, but keeping the house as an investment rental property. Last week, with the crazy rains in Baltimore, I started smelling mildew. I open the door to my crawlspace (which I haven't looked in in 2+ years), and there's some water on the concrete floor. Not an inch of water, but some puddles. So I get a dehumidifier and try to clean it up. I called 3 basement waterproofing companies to get an estimate on fixing the issues. Guy #1 says the water's coming in from the air vents on the walls (there are 3 air vents), and offers a $9900 price. I (using my special powers) negotiate him down to ~$3000, taking out all the bs add-ons. Guy #2 says the water's coming up through the concrete floor, and offers a $7900 estimate. Guy #3 says the water's coming in from the corners, where the floor meets the walls, and it's $6900, but if I decide to go for it today, he'll do it for $4900. All 3 have significant warranties, but #1 (25 years, and shortest warranty) will look the nicest, although I DO NOT think it will solve the problem, just cover it up so no one will see it/know it's there. So...Do I cheap out and go with #1, since I'm moving out, or do I bite the bullet and do it correctly? Anyone know any HONEST waterproofers How do 3 guys, who all claim 20+ years in the industry come up with 3 different conclusions???
