You should use this "do it yourself" test to see if the issue of your water leak is triggered by anything else than inadequate waterproofing before you call a costly waterproofing contractor.

Gutters: Clean the gutters and lower spouts and disinfect them. Even the strongest of the drainage systems in roofing can over time be blocked or the insulating troughs can cause seam breaks or holes. Remove any leaves, scraps or branches from all gutters and drops to test your system.

Use a garden pants to run water through the drill and drain for at least 5-10 minutes to ensure that the water is properly transported.

Society: Test the foundation's slope of soil and landscape. Make sure any water runs down from the house for at least 48'' to 60'.' Unless the water drains, it might pool and run back to the house and cause water damage and mold problems.

Leaks: Search for leaky valves or robinets under your sinks, toilets etc. Use a flashlight to drag all water lines into the basement or crawling space through the building. Be sure to check the pipes before they enter the house. Enter any loose dirt or rock in search of drips along the sides. If required, have any washbasis structures set.

Supply lines: Search for leakage and declines along the seals of the water supply pipes. Over time, water pipes can rot or deteriorate, which can affect the waterproofing around tubing attachments and coils by freezing cold. Turn off all your heating, including your icemaker, to check for leaks. Write your water meter. Read your water meter. Now wait thirty to sixty minutes and read the meter again. You have an undetected leak if the meter has adjusted. You don't need a waterproofing pro if you have a leak.

Basement: Test wetness or drainage of your cellar walls. The easiest way to do that is to take a 12 "piece of aluminum foil and seal it against the surface of a wall suspected of being suspicious. Seal all the edges tightly. Then, just wait a day or two to test the foil. If the outside moist, that comes from condensation; if the inside wet, it comes from the spring http://www.flexcontracting.com
