Where's the option for "none"? We don't have any. Well we have drywall, I guess. But no sill on top of that. LOL

Wood.

Wood.

(Marble? I don't live in a palace. LOL!)

Wood. 1939 pieces put together, rather than the one-piece type used these days.

Wood, our new build has 6 inch walls so that gives us a nice deep sill.

Wood. If our sink window sill was deeper I would have put our counter soapstone for plants to sit on.

Wood.

Another FL house with marble (except in our remodeled master bath where we have granite). Like voila said, most in FL have marble.

We have wood windowsills. Fascinating that FL houses have marble. I have seen a trend in having no trim on window (drywall only on sills) in newer builds as a way to save some money.

Oh, I guess that makes perfect sense in a concrete home!

wood ,live in the NE...house originally came with black 4x4 tile sills., we replaced as we put in all new windows....all sills are stained and polyurethaned....oops, forgot my kitchen sill is granite, same as counters.

Mine are wood (both stained/glazed and painted), with the exception of the over-sink kitchen window and window in one bath where they are tile. 1955 house....

Drywall. It's a 35-year-old ranchburger that we had to upgrade with AC, carpets, drapes, paint and all new windows and French doors. It's still a ranchburger, but you can't beat the view.

Another one with drywall only. Except in the kitchen, where I put granite behind sink and up into window sill.

Same as Errant, drywall only. Put in granite behind the sink. Most homes here built in the last few decades only have drywall, no molding around the windows.

Wood, except the windows behind the kitchen sink are marble now.

None. We have plastered interior walls and the plaster just smoothies into the window. We have no window trim on the interior or exterior.

I have wood, but there was a time while living in Ca where 3" of drywall was considered a 'sill', and the price of the house was. 3 times what I paid for the house I live in now. Sunshine doesn't come cheap.

Painted wood (stained in the den) and a granite sill in the kitchen.

Wood (poplar), sealed with GARDZ and painted with Pro Classic. I used cedar to frame the enclosed patio trim and sills.

When newer builds eliminate sills and casing trim, the builder and buyer do save a lot of money. Wood trim adds about $150 per opening if using vinyl new construction windows. Consider material like jambs, stops and casing trim. A carpenter to install and a painter to sand, caulk, paint or stain. $$. Most drywall openings use wood stops. Really inexpensive drywall openings eliminate any wood by using vinyl J bead and caulk to hide joint.

When building with a wood window, the labor up-charge is about $300+ to cover accessories and finishing.

My sister had a college friend who lived in the $ Beverly neighborhood of Chicago - their brick house hse had marble windowsills plus custom fitted plate glass slips/inserts over the marble

Also remember the Boehm birds displayed on them as well.

Florida resident here. 1950s block house. Sills were 4x4bullnose tile but have. Replaced with marble sills.

Wood. In my mother's house they are slate.

Wood. Old farm outbuilding, so the sills are very deep, which I love.

Wood except for the bathroom window that's in the shower and gets wet. That one sill is corian.

Wood, in an old house.

To those who have drywall sills--if rain comes in through an open window does it cause damage? Before we put in AC, we always had to run around closing windows on the windward side, if an unexpected shower popped up.

Marble

I wish I had marble because the kind I have (wood) get scratched up by mog dog.

Another 50s concrete house in FL - still have original ceramic tile sills.

I had forgotten that I do have a granite sill in my bathroom over the tub! :-)

Ours are wood but we replaced the low ones (that our dogs like to perch on to bark at dangerous pedestrians) with fake marble - like some bathroom counters. You don't really notice them at all (they look like painted wood form a short distance) but your sure did notice the scratched up wooden ones.

Painted wood, a full 8" deep because of the thick ICF walls. The cat is in heaven!

When I lived in Europe, all of the houses had marble window sills. Since nearly all of the windows had flowers growing inside on the sill, I always thought that marble was used so that the water from the plants wouldn't rot wood sills. Probably not correct, but it is what I thought. I always wanted marble window sills in my own home after living over there, but have never had them.
