"ErieHome waterproofed my basement. The crew was polite, kind, and came in, did an excellent job in 3 days by digging a trench on the inside of the basement, removing the dirt from the bottom of the foundation, installed corrugated tubing, rock and then cement. They also installed a Humidex airpurifier and new sump pump with a backup pump. They cleaned up afterward. Any questions I had were answered in a respectful manor. I now have peace of mind knowing that I no longer have to monitor weather forecasts for rain or have to clean up anymore incoming water. The system is warranted for the life of the house and included within the price, which increased the value of my home."

"They are great to work with. Communication was superior. They stand by their work. A few years ago I had waterproofing done in my basement and this time they spray foamed the cavities of the basement too. Both times they did awesome work and cleaned up too! I highly recommend this company!"

"Project: Radon Mitigation Jordan explained what was being done for the project. He was very thorough in making sure the crawl space would be sealed and vacuum was proper in the crawl and basement. I would recommend Gardner Environmental to anyone needing Radon mitigation work."

"We met with the estimator/salesman Kevin who inspected the entire area, performed measurements and then reviewed the cost proposal in detail with us. He was very knowledgeable and thorough, explaining the process in layman's terms so we had a good understanding of what was needed and why. It was nice to get an idea of the cost right away instead of waiting days/weeks for an estimate. We secured estimates from other contractors and we decided on Tri-State due to the overall cost, professionalism and good reviews/references. Tri-State was able to schedule the job within a couple weeks. They provided us great preparation information so our basement would be ready for them to begin the work without delay. The crew worked over a two day period, keeping dust/mess to a minimum. All team members were professional and worked hard during the process. Clean up of the basement, staircase and outside area was excellent and additional instructions were given to us upon their departure. We have had several good rains since install and have had no water/wetness in the basement. Will edit the review accordingly to let members know how the system worked after a year or so."

"When we bought our house, there were several cracks in the basement foundation walls - we were assured that the prior owners never had any problem with water leakage through them. However, once we lived there we discovered that every so often, under certain conditions, water would indeed leak through - and while it was never a lot of water, was in the unfinished part of the basement, and never caused any terrible problems, we always knew this was something we really should take care of at some point. So "Repair Basement Wall Cracks" was added to our "To Do List" ... where it remained for almost 10 years!  <br /> But at last it made it to the top of the list - the time had come! We contacted Dry Otter Basement Waterproofing after reading their excellent reviews on Angie's List, and were very pleased with their service. Co-owner Nick was very helpful and responsive when we were making the initial inquiries, the work was scheduled in short order, and the two workers who came to do the job were excellent - they were helpful, friendly, knowledgeable, and willing to explain the procedure and discuss some options for the project. They left the job site very clean as well.  <br /> The repairs look great - we have every confidence that we will have a dry basement going forward. If it did turn out that some issues remain, Dry Otter's excellent warranty and professionalism would make us have no hesitation in contacting them again to diagnose and address any remaining problems. <br />"

"The project went very well! Mike is terrific. The crew came as scheduled. Explained what they would be doing and did a nice job.The first part of the project involved trenching the basement floor along the three walls. This was the dusty and loudest part of the work since they use electric jack hammers. Make sure you cover everything. They did a great job cleaning up the area they worked in but you will still have dust. We had a minor problem and came to a mutual agreement for solution. Nice people to work with, great job!"

"Everything went very well. My husband did the prep work they requested (removing paneling and drywall to 18 inches above the floor, cutting the wood studs to that level, and removing carpeting to six inches away from the wall). Two workers from Badger Basement came to our house and were completely done in only two hours. They jackhammered out the existing concrete slab, installed metal channels in the wall to drain any moisture out beyond the foundation, installed a sump pump in the room's closet, and poured fresh concrete to fill the new trench. All work done very professionally and thoroughly."

"The painters took great care in making sure items were covered to prevent getting any paint on them. They were very courteous and took great care in moving furniture around so they could get the painting done. At the end of each day, they made sure before they cleaned up that they asked me to take a look their work to make sure it was to my satisfaction. I would recommend Plewa Property Services to my friends as they were very reasonable and did excellent work."

"Terry did another amazing job! He came prepared with everything he thought he would need (as you know when it comes to plumbing, nothing works the way you expect) and made a quick run when he needed something to complete the job. When he was done, he even dry walked the hole for me, which is what he always does...goes above and beyond. My washing machine runs perfectly and I no longer have to worry about old piping. Terry explained what he was doing every step of the way and answered all my questions."

FAQs for foundation, basement or crawlspace waterproofing / encapsulation projects in Janesville, WI

The most affordable way to waterproof your basement is with interior methods like waterproof paint, costing between $1 and $8 per square foot, or silicate concrete sealers priced at $4 to $6 per square foot. However, these solutions are only suitable for certain issues. If your basement moisture is due to more serious problems like a cracked foundation, you'll need more extensive (and costly) repairs.

Absolutely! Waterproofing your basement is a smart investment that can increase your home's value. By keeping your basement dry and free of moisture problems, you protect your home's structural integrity and make it more appealing to potential buyers. Plus, taking proactive measures now can prevent costly water damage repairs down the line.

The time required to waterproof a basement depends on the selected method. Some approaches to interior waterproofing, like paint or sealant, can be completed within a day. Installing new drains or weeping tiles will need at least two to three days of labor. Any forms of exterior waterproofing that require you to excavate land will require an additional three days of work to prepare the ground.

Yes, basement waterproofing can significantly increase your home's value. A dry, leak-free basement is a strong selling point for potential buyers, enhancing your property's desirability and market price. Investing in professional waterproofing not only protects your home's structural integrity but also ensures a healthier living environment by preventing mold and mildew growth.

Waterproofing both the interior and exterior of your basement offers the best protection against moisture. Exterior waterproofing stops water from penetrating your foundation, while interior methods manage any moisture that does enter. If you must choose one, exterior waterproofing is generally more effective, as it prevents water from reaching your home's interior in the first place.
