BWW Project #39 Rework Rear Garage Door

 BWW Project #39:  Rework Rear Garage Door

The threshold under the rear garage door is wide open and water comes through.  The sides of the doorframe are rotted out as well.  Ther final piece of the water problem in that area is to button this problem up.

First of all, I installed 1 X 3 sisters to the outside of the existing vertical door frame pieces and screwed them to the studs and the old frame.  They sit on six inch starters of pressure-treated wood to slow deterioration in the future if water gets in.  The pressure treated wood rests on 30-year cement caulk which fills up the cavities to the left and right of the threshold.  This seals up the sides quite nicely and also much improves the lock throw receiver, which previously was just loosely screwed into the old wood.

Cathy then put silicon caulk all around on the inside.  

Both the inside and outside of the threshold itself were then secured by beads of cement caulk to the concrete below, which forms another water seal.  The water will now have to build up to a level high enough to flow over the top of the threshold in order to get into the garage.  That will take a big rain event and will not commonly happen.

Now the water drainage problem needs only maintenance from time to time. Keeping the eavestrough water draining, keeping the drainage chute clear and slanted, keeping the water egress routes open and grassed, and keeping clear and open, the final drain routes under the kayaks and north and south of this little trench.
