"The entire process from the initial quote delivered by Alex Heigle to job completion was handled with a great deal of professionalism and care. The crew from the Inver Grove Heights Branch: Erik, Jeremy and Jeremiah did great work with stabilizing our sinking garage. At times they had to make course corrections to overcome issues that popped up. However all the alternatives were explained plainly and in great detail so we could make sound decisions. We were very satisfied with the quality of our newly, renovated garage foundation. We would highly recommend Innovative Basement Authority."

Constant problems with plumbing throughout the home may point toward the plumbing vent being the culprit. If a blockage or clog occurs in the plumbing vent, it can quickly lead to the entire plumbing system throughout the home failing. Tackle clogs as soon as they happen, and if it’s a constant problem, bring in a local plumber to look at repairs.

Be on the lookout for multiple points of the plumbing system causing problems, such as if there’s a strong scent coming from the home or if you notice the plumbing vent on the roof is damaged.

Tipping is not required when hiring plumbing professionals. The rate provided in your plumbing quote is intended to cover all of the labor required to get the job done.
