Q–We had additional insulation blown into our attic, and the contractor told us that we needed extra vents in the overhanging eaves or soffits. Can you explain why this is necessary?
A–Vents at the top of each attic peak are usually not enough to provide adequate ventilation to prevent condensation in an insulated attic.
You need vents along the bottom–in other words, in the overhanging eaves or soffit areas. These would allow air to flow in and circulate naturally upward and out through the peaks at the top.
These vents are covered with screens and louvers, and may be in one long continuous strip, or in numerous sections. Make sure that the openings are not covered or blocked by insulation on the inside.
Q–We used a cream polish to protect the finish on our dining table, which has a glossy lacquer finish. As a result, the surface has become cloudy looking. How can we remove the polish?
A–Because I don’t know the type of polish used, or what solvent it contains, it is hard to say what can be safely used. Contact the manufacturer to see what he suggests.
If you want to experiment, try a small amount of mild detergent and water in one corner, or try mineral spirits (paint thinner)–again on a small corner at first.
This will remove most polishes and waxes, but it should not harm a lacquer finish. As soon as the polish seems to soften or dissolve, promptly wipe off the solvent with a clean rag.
Q–I have been thinking about painting over the wallpaper in our bedroom rather than removing it because the paper was put up to hide imperfections in the wall. Do you think this is practical? How should it be done?
A–Wallpaper can be painted over with any latex paint, although it’s often best to apply a sealer first. I usually don’t recommend painting over wallpaper, however, because once it has been painted, removing it will be many times more difficult. In fact, it is sometimes almost impossible to do without damaging the drywall panels underneath.
Q–We live in a 35-year-old house, and I recently noticed a crack running across the living room ceiling and then down one wall. The crack seems to continue along the ceiling of the adjoining hallway.
What might be causing this? Could it be a serious problem?
A–It could be simple cracking of the plaster due to slight settling of the foundation, or it could be due to warping of beams or joists.
There is also the possibility of a more serious structural problem. You may need to install additional supporting posts in the basement.
Call a local engineer, contractor or architect to inspect the premises and advise on you what, if anything, is needed.
