Any recommendations for someone or a company that is good in diagnosing difficult problems like this and doing whatever it needs to be fixed - windows, grading, etc.?
Thank you,

Before you look for a company/handyman to do a fix you need to look carefully what happens during a heavy rain to narrow the possibilities. Water will find any anomalies to exploit.
Many posters have provided good ideas that may help. To get a higher probability of success you need to eliminate some potential causes.
Background Info:
Lanais are designed to handle rain blowing in by having a slope and drainage to the lower level outside. However when you enclose the lanai keeping the rain completely out is a challenge.
1. Do you have rain gutters that take the rainwater away from the house? If not the wind can push a lot of the rain against your windows and overload the sliding door drainage channels.
2. Do you have outside patios or concrete slabs adjacent to the lanai? These surfaces will cause splashing up onto the sliding doors especially if you do not have rain gutters around the lanai.. The sliding door channels should have cutouts to allow drain water to drain outside and have continuous channel inside to keep rain out.
These slabs can affect drainage outside especially if you have the expansion/contraction grooves cut into your lanai floor slab. It looks like you have a finished floor and may have filled in these grooves. During Hurricane Irma I had water coming from the birdcage though one of the groves that found its way through all of the grooves in the lanai and mostly draining out through the low side. After wet vac for several hours my wife spotted the groove where the water came in and I stuffed the crack with flexible foam and used a screw driver to pack it completely to stop the inflow. The problem has not returned.
3, It looks like you have rocks outside and probably weed cloth which greatly reduced water seepage. As mentioned previously pull rocks and mulch away from the slab to made sure you do not have ponding at the slab. Look at the grooves that were cut into the slab. Are grooves free draining?
4. Where does the water come in? If you can't be there all the time put some dry sponges along windows and it may help identify where the water enters.
I hope this helps a bit in looking for the solution to your problem.
