retrofit patio door question

I live in the San Francisco bay area and have a question on retrofit patio door question. People who have installed such doors keeping the old frame (except the bottom one) - is the loss of glass significant? How about the loss of light compared to the old door?

Do you have the same question? Follow this Question

    I install windows and doors for a living. I don't claim to be a know-it-all, but I do have a couple of comments. First of all, the amount of glass and light you lose depends on how much smaller the new door is. A couple of inches may be noticeable but not significant. More will be more. It's a little difficult to answer your question for a couple of reasons. First, significant, is subjective. I don't know what's significant to you. Environment is another factor. Does the door face direct sunlight or is it shaded. The less light the door receives, the more size matters. And visa versa.

    Another thing to consider is why the old frame is being left in. Doors are not all the same size. A new door the same size as yours may not be available. Or a different brand may fit your opening better and allow for removal of the old frame. Most manufacturers can give you sizes and your contractor should be able to help you also.

    What you might do to judge the effect of less glass is block off the existing door with cardboard or tape or something.

    Good luck
