Requested a quote after a sinkhole opened up near my foundation. Terry got back to me the same day, and was available to come by for a quote the very next day. He inspected everything, and suggested that I could fill in the hole myself as a DIY job to save some money, and provided me with a thorough explanation of everything I would need to do to solve the problem, free of charge! Terry was prompt, friendly and helpful throughout the process, and helped me out a lot.

Terry and his team were fantastic to work with from start to finish. Communication was excellent throughout. We ran into a number of issues during our basement renovation, but they always showed us what the issue was and then provided us with various options to fix them moving forward. The quality of work done exceeded my expectations and we couldn't be happier. We will definitely be calling them back for any future renovations we do, or foundation problems (but hopefully not for that!).

Terry and his team are always punctual, professional and ready to go. From start to finish always a pleasure to deal with and have in the house. They leave it clean and tidy every night which was greatly appreciated. I highly recommend Renco for any renovations you’re looking to have completed, you won’t regret it!

Renco was extremely professional to deal with. Terry in particular responded to my email inquiry quickly, came out to assess the work. I had the quote by the end of the day, and his very talented and detail oriented team member, Blair repaired all the drywall issues.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.

Terry was extremely responsive, and gave a very good explanation of options and work to be done. I unfortunately forgot the name of the tech that did the crack repair, but they were very friendly, thorough, and explained the how/what/why of each step of the repair.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 is knowledgeable, quick to respond to emails, and charges a fair rate for his work. We have hired his team twice now and would hire them again.

I’ve worked with Renco twice now, first in late fall when I had a surprise leak and needed a quick interior patch and again in the summer with an exterior follow up. I received a number of quotes but found Terry’s to be the clearest in terms of the required work, with a scaleable job that met my needs. Both times I worked with Terry he and the team were super reliable and communicative. Many of the other foundation quotes I got didn’t provide this level of communication or seemed to care about diagnosing the issue. We had a number of questions about the impacts of the work and all were addressed clearly. No waiting around and the job itself went very smoothly. He also threw in free landscaping which was really appreciated. Thanks again Terry and to your team, we’re super happy with the job!

Excellent and timely service at a very fair price.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%.

We worked with Renco Home Improvements to repair a small foundation crack in our unfinished basement which had just started leaking and which needed to be repaired from inside the house. The job required removal of drywall and insulating materials in order to access the full length of the crack. Terry, the owner, responded very quickly to our request and scheduled the work very promptly. Ty, the technican, did a great job. He explained the process every step of the way and was very methodical in executing the work. All went very smoothly and once the crack was properly repaired, Ty replaced all insulating materials and drywall and left the whole work area very clean. It was a pleasure to work with Ty and we are very happy with both the process and outcomes. We won’t hesitate to work with Renco again.

Over the course of a basement reno, we discovered two basement walls that were bowing from hydrostatic pressure. We contacted a few companies and Terry was the most responsive from the get go in working with us and an engineer to identify a practical solution that was cost-effective.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.

Terry is very patient. He explained what the procedure was for repairing cracks in the foundation of my home. The quote I was given was accurate and so easy to pay with an e-transfer. The workers that came into my home were professional and explained what they were doing. They worked quietly and cleanly. 100% recommendation of RENCO.

Terry is a totally professional and knowledgeable repair specialist. As opposed to other companies that want to up-sell when doing foundation repair, Terry performed a prompt and totally thorough inspection, identifying the specific foundation repair needed, provided loads of information, and answered all our questions. The repair was done promptly and professionally by one of his courteous and knowledgeable technicians. We super recommend Renco for your foundation problems.

I would like to thank Terry for his professionalism in his quick response to do an initial inspection and the valuable advice provided to me. My problem was not as serious as I had initially thought. Terry provided detailed information regarding his assessment of the issue, some repair actions I can do myself, and transparent cost breakdown in-case the issue develops further. I won't hesitate to request his services again in the future and refer him to my friends.

RENCO HOME IMPROVEMENTRenco 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.

Terry and his crew repaired my basement crack in 2019 and issued a life-time warranty certification on the job they have done. In 2021, there was an issue around the same area and Terry was able to honor the warranty and repaired the issue. Blair was very friendly and has done a great job to address the issue promptly.

Terry came by for a look at my basement today and was very honest regarding what work needed (or in my case didn’t) need to be done. Didn’t pressure me and answered any questions I had, even gave me some advice on how to handle some minor issues myself. Appreciated his transparency and taking the time to come personally.

I called Renco for advice on repairing multiple foundation cracks in my basement. I was concerned about structural foundation issues. Terry came to inspect the cracks and provided options for repair.The foundation repair job was done the next week and I have had no issues since. Happy with the service.

Renco just finished repairing some water leaks in my kitchen nook area and crack in my basement foundation. Terry is the face of the company, very friendly, knowledgeable and overall amazing to deal with. His crew was extremely courteous, meticulous and professional. Having lived in my house 13 years with this problem from the start, both the builder and another contractor could not figure out the problem causing the leak. Terry did a quick inspection, found the problem, fixed the area leaking and recommended a wait period to ensure no more water entered. His crew repaired all the interior damaged areas beyond expectations.

Our Step-by-Step Waterproofing Process

Renco Home Improvements follows a proven step-by-step basement waterproofing process backed by a written lifetime warranty.

basement-leak-prevention

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!
