i think you'll be fine. in a stripped down condition, with no furniture or decor on the lanai, it will show. but once you have other things to look at it wont matter so much....but...

do keep in mind it wont just be trim that will be different, the color of the glass could look different as well. if it was the front of the house i wouldnt like it, for this back U i think its acceptable.

i think french doors and sliders would look worse, so no win in that direction anyway.

have you spoken with your insurance company? they may require hurricane resilient doors for replacements. here in RI i had a choice of 'hurricane rated, or pre cut and sized plywood on site' for both a replacement and new windows. i just dont want you to be caught in an unpleasant way if you were to need to make a claim in the future.

I have exterior shade screens on my sliders to prevent fading/heat gain. Much cheaper than a replacement door but not sure you would want to do that on only 2 of 4 doors. Does the existing tint not block sun fading/heat?

I think you're fine replacing just the two. I had new tracks and rollers put on my slider for $340 for the whole door. Now we have to be careful not to pull the door too hard because they slide closed so easily. You may be able to add another layer of tint to the windows as well.

That's very true. You'll definitely notice a savings in your A/C bill as well. I don't think you'll see enough of a difference in tint color or frame size to worry about it.

New sliders definitely, but rethink Pella...........

My sister replaced a patio door in Miami, and it required a permit. I don't know if her situation had any special considerations. It sounds like you've been doing your homework, but I share this with you in case you need to check with your contractor about pulling a permit.

To answer your question, I think it will look fine as you'll still have symmetry. And as another comment mentioned, your furnishings will dominate the space, and that's where eyes will go. Good luck!

"Why rethink Pella? They have a great reputation. We also considered Jeldwyn"

Not amongst pro's. And Jeldwen is right next to them at the bottom of the barrel.

Do you need impact rated? Who will install?

Marvin Integrity, Andersen 400 series, Sunrise or Okna.

"No, we don't need impact rated as we are replacing less than 25 percent of windows."

Sherry W:

Whether or not you need an impact rated door or window depends on your specific location in Florida, not the amount of windows you're replacing.

Paella has a 'contemporary' model. The stiles are much thinner. Do not know the quality. I came across it earlier today when searching for fully opening of both panels of sliders like I had years ago.

Thanks for the information.
