Q: I have renovated my basement and have put in nice furniture, rugs, lamps and so forth. However, the basement is almost all underground, and the windows are small and close to the ceiling. Is there anything I can do to improve the windows? Curtains don't help much. -- Dandra

A: There are special large basement windows called egress window systems. These are big enough to provide an escape route from the basement in an emergency. Retrofit installations are possible, but they require digging large window wells and making changes to the foundation. The finished project can be quite attractive, with the well lined with masonry blocks. Translucent or transparent well covers let light into the well and the basement. If you consider such a project, make sure the contractor is experienced and fully insured.

If an egress system seems impractical, it is also possible to deepen your window wells enough to allow somewhat larger windows to be installed. Again, an expert contractor will be needed to safely make changes to the foundation.

The concrete floor in our older house has suddenly developed seepage in just one spot. The seepage does not seem to be related to rain. Is it worth bringing in an expert to check? -- Hinkles

I suspect that a pipe under the concrete has sprung a leak. If so, it will probably get worse and pose a more serious problem. Have a plumber check it out.

Our outdoor limestone steps are badly stained. What cleaner can I use without damaging them? -- A. Giella

Limestone is a natural stone that can be damaged by strong cleaners.

Several special cleaners are available, and one that should do the job is Sure Klean Limestone & Marble Cleaner by Prosoco ( http://www.prosoco.com).

Before using any cleaner on your limestone, test it first in an inconspicuous place to make sure there is no damage to the stone.
