Renco Basement Waterproofing Reviews
We take pride in every job, no matter how small or large. Our customer reviews, feedback and repeat work reflect this.

They cleaned up promptly and did the complete job in 10 days.
We were kept in the loop about what they were doing and everyone was polite and answered our questions. We highly recommend Renco for foundation repair. Don
Renco was tasked with fixing the mistakes another company had made to my basement repair work after some water damage. I couldn’t be happier with the service, speediness and quality of work from Renco.
I will recommend them to anyone and I would absolutely like them to do more work in the future at my home.
Most important, I was told several times that RenCo 1000% stands by their work, and to not hesitate to reach out if I had any concerns or if anything comes up.
RenCo also does home improvement/renovations, and we just might contract them for this too, thanks to our good experience with the crack repair.
Terry found the crack nobody could find and sent someone to repair it within a week. It was in a tight spot behind my furnace, which required disassembly. He got an HVAC guy out to disassemble and reassemble the ductwork when he was done. Ty, the technician, did a beautiful repair job, and a perfect clean up. It looks way better than it did even before all of this happened. I'm so happy with the service and the rapport with Terry and all his contractors.
Recommend 100%.
I Highly recommend, easy to work with and prompt service at a great price. Thanks Reno!
Terry's crew showed up everyday during the repair process and he was extremely responsive throughout. Dealing with a problem of this type for the first time as homeowners, he was always available to answer our questions and provided clear explanations.
Renco Home Improvements (Renco) just completed a basement foundation repair work on our company’s Industrial unit where we had a basement flooding problem.
Terry was professional in his approach. I gave his company a call and left a message. Terry called me back to make an appointment to view the property. After Inspection, he gave me a quote with an estimated time for completion.
Thought there was a slight delay in starting, Renco did a great job within the estimated time frame and on budget and left the property in a clean state.
I would happily recommend Renco for consideration by anyone looking to have work done on their foundation.
The foundation repair job was done the next week and I have had no issues since. Happy with the service.

Our Step-by-Step Waterproofing Process
Renco Home Improvements follows a proven step-by-step basement waterproofing process backed by a written lifetime warranty.
Step 1: Foundation Excavation:
The foundation waterproofing process starts with the excavation of the soil surrounding your foundation all the way to the footing. We then examine the existing drainage system and the condition of the foundation wall and footing, and power-wash the foundation in order to properly examine it for damage.
Step 2: Foundation Crack Repair:
This step may vary, depending on whether or not your foundation actually needs repairs. If our excavation and washing of your foundation has found any damage, we will repair it.
Step 3: Adding Footing Bevel:
The seam where the foundation meets the footing is the most vulnerable part of your foundation that will typically allow water to seep through into your basement. Adding a concrete bevel around the footing will help to seal it up and prevent water from leaking through.
Step 4: Blueskin Waterproof Membrane Installation:
Blueskin is a membrane consisting of rubberized asphalt and polyethylene. It provides a reliable physical barrier that is waterproof, tough and flexible, stretching with your foundation as new cracks appear and providing consistent protection. It is installed on top of a primer material that provides an adhesive surface that lends some amount of dampness protection in itself. Note that the Blueskin membrane provides waterproofing protection and not simply damp-proofing.
Step 5: Protective Air Gap Membrane Installation:
The air gap membrane is a physical first defense against water which also protects the Blueskin membrane. Air gap membrane is a tough high-density polyethylene sheet that keeps water out. The dimpled structure of the membrane allows any water that slipped past it to drain away and not get trapped between the two membranes.
Step 6: New Drainage Tile Installation:
The following two steps in our basement waterproofing process are particularly important, and they involve proper drainage installation and grading. As the Blueskin and air gap membranes do their job of barring water from entering your foundation, they need to be supplemented by a system that drains that water away.
Whatever drainage system you are connected to, be it a city storm drain, a French drain on your property or a sump pit in your basement, we need to install new drainage tile to reach it. In doing this, we lay down a new bed of gravel at your foundation’s footing, and install new window wells and drains if necessary. The new drainage tile is then covered with gravel so that water can easily drain through it.
Step 7: Proper Grading:
Ensuring proper grading is the final crucial step in the whole waterproofing process. After the foundation waterproofing steps are done, we fill up the excavation around the foundation and create a grade or slope around the house to cause water to flow away from it. It may sound simple, but keeping water from getting to the foundation in the first place is the key to ensuring your basement stays dry.
Step 8: Leaving Your Property as We Found It (or Better):
Our service doesn’t stop at providing you with reliable foundation repair and waterproofing. Unlike many foundation repair companies we don’t leave your property without restoring it to its original condition or even better. We have expert landscapers that will come in to clean up, lay down sod and remove any unnecessary waste leaving your property looking the same as it did before, if not better!
