Inspected a 50 year old home on Saturday that had originally been a cottage sitting on blocks, which was raised onto a full basement foundation in 1988. A double wide driveway slopes over a distance of about 35 feet to the garage floor, which is level with the basement. Basement is about 5 feet below grade. The only drainage for this natural "catch basin" is a 1 1/4 inch pipe opening flush with the concrete outside the garage door. The pipe leads to a small sediment pit inside the garage, which is drained by another 1 1/4 inch pipe (I don't know where it drains to, if I was the homeowner I would hope the storm sewers). The whole setup is kind of scary. The man door to the house is just a cheap plywood veneered door, no closer. A lot of the supply and drainage plumbing for the house is exposed, hanging below the garage ceiling. A lot of drywall was removed to install this plumbing, hence no gas tight barrier between the garage and the house. All of this plumbing would freeze in the winter (southern Ontario) except there is a hot air vent and cold air return in the garage. Now I have several times commented to clients, while trying to explain the importance of proper grading, roof gutters, etc. that a basement is basically just a hole in the ground. If you don't take certain measures, nature tries to fill the hole with water. I've never been partial to basement level garages with sloping driveways, because this arrangement just acts to funnel more water into the hole (not to mention the problems of driving your car up a snowy or ice-covered driveway). While trying not to sound too alarming, my report did make mention all of the water stains on the wood paneling and concrete in the basement (basically all the wall areas below four inches), the loose floor tiles, and the presence of two (not one.......two) sump pumps. I was careful to explain the implications of questionable drainage, and recommended having a basement waterproofing contractor evaluate the drainage system. I don't like passing the buck like this, but I am honest about my limitations. The buyers (a couple near retirement age) were happy with my verbal assessment on Saturday, but their agent called this morning to say that my report had them spooked, they were walking away from the deal. I'm a rookie in this profession, about 100 inspections so far. I have some background in homebuilding and renovation, but I often have trouble with the wording in my reports. How could I present a balanced assessment of this garage and basement, without glossing over the possible problems, and without sounding like Chicken Little ("the sky is falling!). Is a 1 1/4 inch drain big enough? Would the interlocking brick on the driveway, being a permeable surface, really catch and funnel much water? Naturally, I have been getting a lot of referrals from this realtor (probably 25 percent of my business so far), but I need to be able to sleep at night.
