"All commincation was fast and professional. The crew arrived as scheduled and went right to work. The install took an extra day and was easily scheduled and completed," in fact, the crew stayed very late the last night to ensure the job was finished. The quality of the work is outstanding and
's team was always happy to help.

"Their waterproofing procedure is more extensive and effective than the usual type you see in TV ads. They are very thorough about finding and eliminating the source" of the problem from the outside -- even located and (relatively) easily repaired the source of a potentially major underground leak on the opposite side of the basement before it would have required a whole separate excavation. We can't say enough good things about the crew and the quality of their work. Every one of the guys was extremely pleasant, professional and very conscientious about doing the best job possible, making every effort to make sure we were completely satisfied. They carefully re-planted all the shrubbery that had to be removed from around the foundation, and even planted new grass where it had been dug out. They were all truly great to work with. Who would have thought that having a foundation excavated could be a delightful experience?!! We highly recommend them.

Mold in a basement is a common problem. My company helps people with this every day. Some of the answers you received were helpful but not all the information is correct. First, you need to eliminate the two main ingrediants that mold needs to survive. The first one is water intrusion. This is a must. I am assuming you have no water intrusion as you make no mention. The second componant that needs to be eliminated is moisture. Moisture is also humidity. Basements need to be kept airtight in the summer months. Some folks have posted that you need air flow in your basement. Nothing could be furthur from the truth. When you open any windows for example, not one micron of air goes out of the basement, Warm humid air is sucked into the basement. Houses suck air into the basement and it meets the cool surfaces and skyrockets humidity. The windows must be kept closed and a dehumidification device installed to ensure humidity stays below 60% humidity. The dehumidifier should be energy star rated and purchasing a seperate humidity guage is a must to monitor the unit's progress. We like to keep our customer's basements at 50% humidity. This eliminates the smell that is active mold spore growth. Once the water and humidity is brought under control. Remove the organic materials that have mold on them. Walls, sheetrock and studs that have been affected. Follow the advice of previous posts as you must ensure that you do not affect the rest of the home. Once removed, install new walls using as much inorganic material as possible. We also install vapor barrier over the walls and seal the floors to stopwater vapor transmission into the basement. Poly plastic is not a acceptable vapor barrier. It is not "zero-perm" and will still allow moisture transmission. It will also crack and break into pieces over the years. A PVC liner rated "zero-perm" is the correct product in this application. Depending how large the basement is and if it is sectioned off will determine the dehumidifier strength. We use the Santa Fe line of dehidifiers as they are super energy efficiant and work like a dehumidifier on steriods. I hope this helps and I wish you the best in Basement Health!

Where is the home located, what is the exterior wall construction and type, how is the space heated?

 

It could be a whole host of different scenarios that would generate that result.  It is nearly impossible to tell but I would say that most basement moisture problems are a result of bulk moisture intrusion or condensation issues. 

 

Given the deep and hard winter this year, it could be a condensation issue that hadn't previously been shown.

Called the Dr for a second opinion on high humidity. Gave me some estimates and opinions on possible cause. Have not taken any action to date as I wanted to see if humidity stayed high when the rain stopped. We very professional, congenial, and did not charge for the visit. Very thankful for his input.

explained the process completely during his estimate visit and then installed the system in very timely and professional manner. The fan is enclosed in a very sleek black plastic case outside; not the beige flying

you often see. Once installation began, he realized a better route for the pipe to go that would be less intrusive and installed it that way, even though it meant more work for him. Radon dropped from 6.0 to 0.7. We had my daughter use him when she bought her house.

In June I contacted
Le Mars Waterproofing Contractors Provider Name Locked
for a second opinion on a water issue that I was having. A representative from
Le Mars Waterproofing Contractors Provider Name Locked
came to my house within in a day or so and provided me with a detail inspection. As a person who suffers from allergies my concern was mold. The rep informed me that mold was just isolated to one section of the basement and was being caused by a hairline crack in the foundation behind the Sheetrock wall. I opted to have them conduct an air sampling /mold inspection test which included a laboratory report that was extremely detailed. The rep gave me a proposal to fix the crack from the outside and to do mold remediation to my basement.

I was blown away by
Le Mars Waterproofing Contractors Provider Name Locked
and his team! They arrived early, inspected the outside and inside of my house and determined I did not have a foundation issue.
Le Mars Waterproofing Contractors Provider Name Locked
made recommendations for what to do when the issue happens again (watch the gutters, roof, etc.). They were also great with my very excited dog. I was very impressed that they didn't charge me for the visit, or recommend repairs I did not need. If (and when) I have issues with my basement I will definitely use them to do the repairs.

I have an apartment building in which the garden unit had previously suffered water leakage. I had the outside sealed previously, but wanted to get the inside sealed while the apartment was empty.
Le Mars Waterproofing Contractors Provider Name Locked
came out and offered three different solutions all with various price points. We agreed to sealing just the inside for now, and if there were future leaks, we would consider the alternate solutions proposed. In all 6 cracks were discovered.
Le Mars Waterproofing Contractors Provider Name Locked
had the cracks sealed and each of the tie bars sealed. I will be using them again for my other apartment units.

was very professional and offered some good tips to us in regards to how to alleviate future water leaks in our basement. He went outdoors with us and showed us some specific things we could do to keep the basement from leaking. He took this extra time with us even though he knew that we would not be using his services. I would definitely recommend this company to anyone who may be in need of assistance with basement waterproofing!
