"My basement had wall crack steps, horizontal cracks, bowing issues along with moisture issues. Water would come in the basement regularly. Everything was taken care of by RENEW about 6-7 years ago. They replaced some of the foundation bricks, installed a drainage system, placed reinforcement rods along the walls and installed a sump pump. RENEW also helped me with additional request as the project progressed (removing personal items, etc). On the exterior they added and pitched dirt along with placing decorative rocks. I’m writing this 6-7 years later so I’m sure I’ve left a few things out. Since having the work done, my basement has been dry. THERE IS NO WATER/MOISTURE PROBLEMS AT ALL! RENEW is a family business that takes pride in their work. They are dependable, personable, reasonable with cost and most of all knowledgeable. Most reviews are done relatively close to when the work is performed. My review is years later which should tell anyone reading this, they do excellent work at a reasonable price."

"I contacted Accurate Basement Repair after my basement decided to spring a leak this spring. If Iâ m going to be honest, itâ s happened before, but not to the extent that it did this year. Iâ ve held off calling anyone out of fear of how expensive basement repairs can be and I was expecting the worst. Accurate was recommended to me by my mother and by another friend of mine. I called to schedule an estimate and the woman I spoke with was great. A few days later, John came out to my house to inspect my basement. He walked around and looked at everything inside and out. John recommended to do a drain tile test because although I had water coming in thru some cracks in the wall, I was not getting any water in the sump crock. He explained the process to me so I knew exactly what to expect. If youâ re curious on how respectful Accurate will be to your property, John did not want to cut into the carpet in my basement, he wanted to roll it back so it wasnâ t damaged.... I cut the carpet myself. Afterwards he wouldâ ve tried to fix the carpet I cut if I hadnâ t told him not to bother. After the drain tile test was completed, John explained the results to me in such a way that I understood. While my basement may need corrective repairs in the future, John made several recommendations for outside work that he suggested that I try first. If those donâ t work, he said I should do the corrective interior work. It wouldâ ve been really easy for John and Accurate Basement Repair to sell me a completely new drain tile installation to correct the issues I was experiencing with my home and I would not have bat an eye at it. If youâ re looking for a repair company that is trustworthy and honest, you donâ t have to look any further than Accurate. If the exterior repairs donâ t do the trick at my house, I will not have anyone else but Accurate do the interior repairs."

"Matt was up front about the cost and understood our policy to obtain estimates from 3 companies before proceeding with work in our home. He itemized the estimate and explained the procedure and warranty. He was pleasant to work with! He did not require an hour of my time or insist that both my husband and I be present in order to give us a sales pitch. The price was competitive and not inflated to cover marketing expenses. I like that the company is family owned & local, and that the workers are employees, not sub-contractors. The men who did the work were efficient and we have had no water in our basement since the waterproofing was done. I believe the contractors who followed Acculevel's work were a little surprised at the materials used, and they had to adjust their plans somewhat, but all is good in the end. Thank you!"

"Jensen Plumbing is professional, friendly, knowledgeable, and truly cares about their customers! As a new homeowner, I have had plenty of questions, and their entire team has been patient, responsive, and happy to explain things. They even took the time to show me how my new drain tile works and explain how they help prevent water from leaking into my basement. When I had a gas leak, they responded quickly and helped me get a gas shut-off valve installed that my home didn't originally have. They are currently helping me with a leaky shower and guiding me on options that will work with my existing plumbing. Their pricing is reasonable, and they make you feel like family. No question is too silly, and the staff are like talking to family friends. I highly recommend Jensen Plumbing for their expertise, outstanding customer service, and genuine care for their customers!"

Basement Waterproofing FAQs, answered by experts

The purpose of crawl space encapsulation is to prevent mold by blocking moisture and reducing humidity. If the vapor barrier is properly installed, it significantly reduces the chance of mold developing within the crawl space. However, mold can sometimes grow behind the encapsulation material, but it will be sealed away from the main area. Additionally, moisture can still condense inside the encapsulated space, so if you notice excess humidity, installing a dehumidifier is recommended to prevent mold and mildew growth.

Crawl space encapsulation typically lasts between 10 to 20 years. If you experience a catastrophic event, like a flood, or poorly encapsulate your space with low-quality materials, it may only last a decade. Otherwise, as long as you properly maintain your crawl space, a high-quality encapsulation can last more than 20 years.

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Several types of insulation are effective for crawl spaces, with spray foam and rigid foam boards being two of the best options. Closed-cell spray foam insulation is a strong choice because it effectively repels moisture, resists biological growth, seals the air, and provides excellent thermal protection, especially in hard-to-reach areas. Rigid foam insulation boards are another excellent material as they insulate well, resist water damage, and will not settle over time like fiberglass or cellulose.

There are a few downsides to a wet room, the most important of which is the risk of mold growth from the moisture and humidity. Standard bathrooms can have the same issue, but wet rooms are more likely to experience problems because water is less carefully contained. You also have less privacy since the entire bathroom is open, and the room must include waterproofing, which makes wet rooms more expensive to install than regular bathrooms.
