Q: A squirrel or several squirrels ate a hole in my lead flashing, and now it leaks badly when it rains. Water from the roof runs down into the hole. The top of the flashing is cemented into the chimney between the bricks. The job appears to be well done and has lasted many years. The hole is about the size of a squirrel’s head. How can I repair it?
A: The squirrel is doing what it has to do to shorten and sharpen its teeth: gnawing. The lead is just right for him: soft but able to keep wearing down the teeth. Buy a heavy-duty piece of sheet aluminum or galvanized steel big enough to cover the hole and surrounding area. Lead flashing around chimneys is usually not glued to the roof, so lift it carefully, slather the roof and patch with roofing cement, and insert the patch under the flashing. If the flashing is glued to the roof, you can put the patch directly on top.
Putting the patch under the flashing might work better, so keep an eye on the on-top patch and see how long it lasts. Finally, treat the patch with a critter repellent, sold in hardware stores.
Q: I renovated a split-level ranch last year. I am getting septic odors downstairs in my house quite frequently, especially after a family member has showered. Odors seem to be coming from the laundry room where the vent stack is in the house. I’m not sure what’s causing the problem.
A: It sounds as if the vent stack is blocked or unconnected to the shower room and other places. The vent stack takes septic fumes up through the roof, where they are released. An unvented shower, toilet, or other appliance can be dangerous. Have a plumber check it out and clear the stack. Don’t wait; septic gases can be lethal.
Q: My wooden front door has developed a long crack wide enough to see light through it. Can it be sealed with plastic wood or wood filler, or should some other method be taken to save the door?
A: The crack must be in one of the panels, which are thinner than the frame pieces. This was caused by expansion and contraction of the wood. Try this: Buy adhesive caulk that will firm up as hard as plastic wood or wood filler. Fill the crack with this caulk, pressing it in with your fingers. Hold a board on the other side to keep the caulk from oozing through. Let it set. You can scrape it smooth. Do the other side if necessary, and finally paint the panel to match the door.
