Who can assist with the exterior grade on the outside to prevent leaks? A landscaper, foundation expert, or??

My house has hydrostatic water pressure in the walls as well as leaks, mold, mildew, etc. We know we need to change the grade of the outside soil, etc but have only lived in this home for a month and need some guidance. We were going to hire Bdry and start waterproofing from the inside out but I think we should start outside and then we can use drylok on the walls. Any input would be great on what contractor to call for guidance...what type of soil, how high the grade should be, etc. Thanks so much.Who can assist with the exterior grade on the outside to prevent leaks?

You need someone who installs sump pumps and knows drainage. Often contractors who install septic systems know about this type of thing or at least could point you in the right direction. You could also try calling an excavating company.Who can assist with the exterior grade on the outside to prevent leaks? A landscaper, foundation expert, or??
The basic concept is to grade everything to run away from the house. Normally you want about 1/4'; slope per foot of run for proper drainage without obstructions. If any part of your house is subgrade you should trench and water proof from the outside to best prevent water infiltration. There are a number of options depending on your particular situation.
USE A FOUNDATION CONTRACTOR. THIS WILL NOT BE A CHEAP PROCESS. YOU MIGHT BE BETTER OFF HAVING THEM CUT THE CONCRETE FROM THE INSIDE AND PUTTING DRAIN LINES IN THAT WAY. I HAVE DONE THIS WHEN IT WOULD COST WAY TO MUCH TO DIG OUT THE OUTSIDE.

AS FAR AS GRADE. 6'; BELOW SIDING AND THEN THE SLOPE HAS TO FALL AWAY FROM THE HOUSE. BEFORE YOU HAVE SOMEONE DIG UP YOUR YARD, WHAT KIND OF LANDSCAPING DO YOU HAVE AROUND YOU HOUSE? WATERPROOFING ALONE WILL NOT SOLVE YOUR PROBLEM. THEY WILL NEED TO PUT DRAIN LINES, DRAIN ROCK AND POSSIBLE A FRENCH DRAIN SOMEWHERE IN THE YARD TO PUSH WATER AROUND YOUR HOUSE.

CHECK YOUR DOWNSPOUTS ALSO. SEE IF THEY ARE PLUGGED OR HAVE THEM FLOW AWAY FROM THE HOUSE AS FAR AS POSSIBLE.

GOOD LUCK.....
It sounds like the exterior of the house could use a good french drain...this can be installed by a landscaper or yourself if you have the time.



The surface water usually goes down the slope and rides down your foundation wall until it hits a ledge then seeps into the concrete...A french drain take this water around the house into a safer place.



A french drain is a covered ditch filled with a landscapers cloth lining, perforated plastic pipe and gravel. The drain channels the surface water away from important stuff and it's hidden.



Also buy a dehumidifier for the mold and mildew.
