Dear Barry: We recently installed two, large, double-pane windows in our living room, but we ran into a problem. The weather last night was very cold, and warm air from the floor register caused the glass to crack along the bottom edge of one window. It seems that we made a mistake installing the windows so close to the register. The windows are just a few inches above the floor. What do you think? Trudy

Dear Trudy: The apparent errors in this window installation are worse than you realize. Temperature differentials may indeed have caused the crack, although the cause might have been a flaw in the glass edge, as sometimes occurs when glass is roughly cut. There is, however, a bigger issue.

Windows that are larger than nine square feet and are within 18 inches of the floor must be made of tempered safety glass. The fact that your window cracked, instead of disintegrating into small shards, indicates that it is not safety glass. If someone were to walk into one of these windows, major injuries could result, and you could be liable for the costs of those injuries. My advice is to have these windows replaced by a professional glazing contractor.

Dear Barry: I recently bought a 1944 home that needed many repairs. Before buying it, I hired a home inspector, but he missed many of the problems, including windows that won’t open. I’m planning to replace all the windows in the house and have three questions: 1) Shouldn’t my home inspector have reported the faulty windows? 2) Is a building permit required for window replacement? 3) Can they really deny my right to occupy the house until the window replacement is approved? According to the permit application form from the building department, a Certificate of Occupancy cannot be issued until the permit is signed off. Delbert

Dear Delbert: Here are three answers to your three questions:

1. Home inspectors typically test a random sample of windows to ensure that they function properly. When windows are not tested, it is usually because furniture or window coverings restrict access. Ensuring that windows are functional is particularly important in bedrooms and bathrooms. Bedroom windows must be openable and must meet minimum dimension requirements to enable emergency escape by occupants. Bathroom windows must be openable in order to provide ventilation, unless an operable exhaust fan in installed.
2. The building code does not specifically require a permit for window replacements, but it does require permits if you “alter” a building. Some building departments interpret this code to include window replacements, while others do not. However, when window replacements include changes in the wall framing, a permit is more likely to be required.
3. The requirement for a Certificate of Occupancy typically applies to buildings that are under construction, not homes where windows are being replaced.

Before commencing work on your home, check with the local building department for clarification of their requirements.

Dear Barry: We installed new hardwood flooring on our concrete slab floors about 12 years ago. Last winter, we began to notice darkening and buckling of the wood flooring in one area of our hallway. A contractor made some holes in the nearby walls to see if there was any plumbing leakage, but he found no pipes in those walls and everything was dry. So now we have two questions. Should we replace the bad floor-boards before selling the house? And if we leave the floor as it is, will this scare off buyers? Miriam

Dear Miriam: The buckling and darkening of the hall floor-boards are definitely moisture-related, but this is not likely the result of plumbing leakage. A more probable cause is seepage of ground moisture through the concrete slab, possibly at small hairline cracks. This sometimes occurs when the installer of the wood flooring lays the boards without placing a moisture-proof membrane on the slab surface. You can talk to a wood-flooring contractor about possible repairs, but new replacement boards will most likely not match the existing ones. Another solution is simply to disclose the problem to the new buyers when you eventually sell the home. Buyers have differing reactions to disclosed defects. In fact, buyers are often willing to accept defects that are honestly represented, especially if the house is to be remodeled or redecorated anyway.
