I've been living in my house for 10 years, and now want to put it on the market for sale. But first I wanted to fix the water problem in the basement. The house is about 90 years old, and there was always some water seeping out from couple places where the walls meet the floor; especially this past summer, when it rained so much. This was something that I could live with myself, but before I sell the house to someone else, I want to get it fixed. I had estimates from three different companies. The first one (not Basement Pro) seems knowledgeable too, but their price is a lot higher and also for some reason I don't know if I can fully trust the person. The second company is Basement Pro. Pete the inspector recommended a similar solution (as the first company) but his price is much lower. Also, through our conversation, it appears to me that Pete and Basement Pro always want to treat their customers right (which I find out later is absolutely true). The third company used high-pressure sales tactics which I totally dislike (on the other hand talking to Pete was just like having a friendly conversation). Work began at 8:30 in the morning. The crew chief (Donny) has I believe over 25 years of experience in waterproofing. His crew members are all courteous and hard working. I was home the whole day so I was able to see the way they worked. The drainage system was installed in one day. The concrete floor that was poured back looks very smooth. Also, after knowing that I wanted the sump pump discharge to be directed away from the backyard in order to keep it dry, Donny was glad to dig a trench for about 40 feet to run the discharge pipe underground so that the water now goes out to the street. This was done for me at no extra cost. ******FOUNDATION REPAIR****** When I bought the house 10 years ago, the previous owner covered 75% of the walls with new panels. I was happy to buy a house with a finished basement, but it turns out that the foundation walls behind the panels were actually having a lot of problems. To install the drainage system, the crew had to remove the bottom part of the panels. The original idea is that once the drains are installed, the panels will be put back together. However, we could now see that there are cracks in multiple places in the foundation walls. Mike (owner of Basement Pro) came with Pete couple days later and did a thorough examination of the foundation problems. Obviously I was very concerned about how much it would cost. I was prepared to spend the money on a drainage system, but I didn't think there would be any cracks in the foundations. I was also upset as there were signs that the previous owner intentionally tried to hide the problems behind the wall panels. Mike must be sympathizing with my situation, so he said they would repair the foundations at a lot less than the market price to make it affordable for me. So the crew came back two weeks later. The foundation repair included installing 12 carbon fiber straps (which when bonded to the foundation walls will make them a lot stronger), filling the cracks with grout, some digging outside the house, and putting up white shiny panels (called Durawalls) that brighten up the whole basement. The work needs 3 days. Normally all these have to cost a lot more, but I really thank Mike for understanding my situation and making it affordable for me. I highly recommend Basement Pros.
My basement has been leaking due to failing & undersized roof gutters. Al and his team upgraded the entire system so I am looking forward to the next rainstorm to observe the improved runoff handling!

"We were in the process of renovating our apartment and needed to apply for permits from the government, which required an architect-signed design drawing. Anthony came highly recommended.

FAQs for basement leak repair projects in Elsmere, DE
The cost to finish a basement is $18,400 for the average homeowner. However, this cost could be as little as $2,800 or as much as $34,500, depending on the basement size and the materials needed. If your basement is already outfitted with electrical and plumbing, expect the cost to fall on the lower end.
For example, the drywall cost for this project averages around $1,750, but other features, like hiring a plumber, cost between $45 and $200 per hour.
The cost to remodel a basement is between $12,100 and $33,400 for the average homeowner. The price you pay can be as little as $3,500 or as much as $50,200, depending on the size and condition of your basement and the type of remodel you're doing.
If you're doing a simple project like adding a home office to your basement, you can expect to pay anywhere from $500 to $3,000. However, if you're adding a bathroom, which is an extensive project, you can expect to pay between $6,600 to $16,500.
Damp proofing and waterproofing are both methods to help keep your basement dry. Damp proofing keeps soil moisture from entering your basement, which is helpful since your basement is underground. Waterproofing, however, keeps both soil moisture and liquid water out of the basement, which is essential, especially if you live in a wet environment. Because it’s more protective, waterproofing typically costs more than damp proofing.
Although homeowners often use the terms basement remodeling and basement finishing interchangeably, they are quite different terms.
Finishing a basement is the process of taking a basement space that is not habitable and adding elements to make it usable. This includes adding plumbing, flooring, and insulation.
Remodeling a basement means taking an already existing finished basement and changing it, often by adding or removing walls, adding plumbing, or changing the existing flooring.
The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in.
If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500and $5,000 to waterproof, but that price rises significantly for a larger basement.
