Double Door threshold

Can a do-it-yourselfer repair a threshold — or replace the entire door, frame, and threshold?


Q. The threshold on my back door is splitting. I’d like to repair it, or replace the entire door, frame, and threshold. I can’t afford to have it done. How hard is it to install a prehung door? What kind of door should I get, and where? The wood door has a half glass window in the top.

A. You can do either or both. Cut the threshold in two pieces sideways, and pry it out. Cut any protruding nails, and buy a new threshold and nail it right in. If you cannot find a new threshold, use a pressure-treated 2 x 12, cut to the same shape as the old, and make sure you install it at the proper slant for proper runoff. Your old one split because it overhung the wood it was nailed to.

Better yet, install a prehung or setup door, which includes frame and threshold, and is insulated and weather-stripped very well. A wood door and frame is your best buy. Make the door half glass, but choose one with a Colonial type window (6 over 6) which is much stronger than a single pane of glass. Take everything out of the opening, and check the size so you can get the right size to fit snugly. The Brosco catalog shows many such setup doors, available in all lumber and big box stores.

Yes, you can do it, if you are strong and have a strong wife or friend. Those doors are heavy, especially a French double door. I have done three. You can do it.

Q. I have owned my home for 29 years and never had the chimney swept. I have a fireplace that we never use and the house is heated with oil. I’m not sure what the protocol is for having a chimney cleaned. Am I missing the boat on this or am I OK since there has never been a problem?


A. Stand easy. The chimney does not need cleaning, since it has not had wood burned in it. If the house is older than the 29 years you have owned it, and wood was burned in the fireplace, you can have the chimney cleaned but the chimney sweep is unlikely to find much creosote and other byproducts of wood burning.

Trying to install a double french door where

There was only a 2' square window. The doors were bought separate and have no jambs associated with them yet. Going to make my own but need to know a few things from others experienced at this.
1. Should I pre-assemble the doors and jamb before installing them in the opening?
2. if the pre-assembly idea is right, should I add a sill board to the assembly before installing?
3. If a sill board is not a good idea, how much space should I leave at the bottom of the doors for a threshold?
Hope you all have some good suggestions
