"I initially contacted after seeing that I was still getting water in my garage in an area that had been repaired twice by others. They sent" out an estimator within a few days who gave me lots of good advice on several issues that I was having. I thought that I could not afford the work this year and let him know. Then, I changed my mind after we had rain for the first time in months. honored my quote from May and did the work in 1 day. They installed drains in my garage and also put some sealant in the spot where the water was coming in. was very responsive to many questions that I had, and the guy in charge that day had me look things over and also warned us to give the wet cement 4 days to dry completely. It has rained several times since the work was done and the problem seems to be solved. I like also that the work is guaranteed.

Recently the leak water" creates a new water leak channel from the south side of window due to the new building construction of condo. is the service manager of all season water tight and he showed up on Saturday morning and explored the source of water and quickly identify the problem. He explained the source of problem and provided the solution method, showed me the to be installed. The repair work has been completed on time. The cost is very reasonable. Please note that I am a retired Civil Engineer and they are the best contractor I have met. These people know how to handle the leak water problem. They did a wonderful job.

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.

I discovered a damp basement when I was replacing the carpet. PermaDry was one of the contractors I asked a bid for. Of the 3 bids I got and shared with my out-of-state contractor brother, my brother suggested I go with PermaDry. I am so happy I did. was wonderful in explaining what to expect and, even with a last-minute change ...More in the scope of work (not PermaDry's fault), the crew arrived on time and ready to work. and his crew were professional, friendly and far exceeded my expectations. They made a very difficult job look easy. And they left everything as neat and clean as I could ask for. I would highly recommend PermaDry, and and his crew.

I owned a house in , I put it on the in October 2015. After excepting my first offer, I found out during the inspection that I had a water damage in my basement. My Real Estate agent recommended me to and Construction, gave me a bid ...More and was very professional,fast and personable. had great communication and were very efficient, they did the demo and added a french drain and wall guard in my basement. Construction then came in and replaced the sheetrock, baseboards and flooring. They were very clean and worked very fast. Thank you and Construction for making my house sale go through in a timely , I would definitely use both companies again for my future home.

We live in a wet location and have problems with ground water on our property. Several years ago, Perma Dry installed a drain system in our crawlspace to eliminate problems we had with flooding after big storms. It works perfectly. This time, we had them come out to install a French drain along our driveway and also fix a problem with a drain attached ...More to our downspouts. The crew showed-up right on time and completed the job in one day. I am very impressed with the design and quality of workmanship. The crew was professional. These guys are the experts in solving your drainage problems. I think we have solved the problems with drainage that we have been having. They're not cheap, but I think you get what you paid for.

I was told by the PermaDry assessor, in front of the tenant, that installation of their prescribed system would make the basement "bulletproof" from future leaks. Paid $6,400 for full interior perimeter drainage system and pump. They provided a "life of the structure" warranty for the system. There was water intrusion into the basement ...More the next heavy rain. My tenant took pictures of the leaking. I called PermaDry on a Monday to request a tech come out to inspect the leak and was told someone would contact me in 24-48 hours. I got no further response for 72 hours, so I called again, and again, and again. They finally got back to me and sent someone out Friday morning. Friday, Saturday, Sunday, Monday, and Tuesday morning went by before I heard back from the representative after their inspection. They claim the system they installed is working as designed and therefore the leaking is not warrantied. If that is true, then they sold me a $6,400 system that didn't solve the original causes of water intrusion.

took my phone call requesting a bid for a basement wall leak. After my description he advised me of how to set up my own water test to pinpoint the problem. I was reluctant but followed his suggestions and found that the water entry point was a fix that even I (a 70 year old woman) could do myself! ...More I had missed it trying to do my own inspection the day before.
was professional and saved me time and money getting bids and possibly paying for something I didn't need to have done.
He even offered to stop by on his way from another job and take a look at the situation.
This is the type of company that I will not forget, and this company has my business if ever I need a serious problem fixed.

The guy that came out inspected the basement for signs of water damage and looked around the outside and foundation, gave me advice on how to deal with storm water and suggested looking into new gutters and downspouts

No repairs but the inspection was very valuable: explained to me how moisture was entering my basement. I'm a a smart guy but I didn't understand the subtleties. They were able to show me clues to help me understand.

I was expecting a more personal response in email (versus "call to schedule an appointment" but I can see how selling a lot of these deals could make it difficult to read the requested dates of service. Also I read a lot of the reviews on this provider and realized what they were offering would not work for me.
