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!

Angie's Answers

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.




Basement Waterproofing reviews in Redwood City


He arrived on time, was very professional. He explained what he thought of our foundation and what the solution would be. Sent out an estimate by email within a couple of days. Has not called or sent more than one follow up email. I know that we could get a free quote from several others but I felt it was worth it to pay a little and get a quote that didn't have any harassment attached to it! We have gotten free quotes in the past that involved much selling and harassing. I just wanted an honest opinion of the state of our foundation and I felt like that was exactly what we got!

gave us some possible solutions (gutters etc.) for us to solve our issues which we will do before we proceed with using his service. He was very knowledgeable, much more so than other contractors. He took time to carefully study our issue and even dug up a small area to see if there was an issue. Other contractors were quick to solve our issues with spending our money on lots of costly work. We will definitely hire him if we end up needing more of his help. Highly recommended!

came out to look at the work to be performed the day before the job, and explained a better way to excavate the dirt and debris that that they would need to remove from my basement--a way that I for one never thought of--through the basement window. I had to pay a little more for a new basement glass block window--but it was well worth the minor additional cost as i now have more light in my basement and it's beautiful--who would ever think you could say that about a basement!.
Before the

crew I was miserable with my basement, i couldn't store any items of value, it was always wet, or damp down there and I needed piece of mind from the threat of my foundation eventually crumbling, mold, mildew and and goodness knows what else from entering my home.
After the Water Proofing One crew waterproofed and finished my basement, my daughter and I have been able to store our belongings in our basement with confidence that nothing will be ruined by any more water. We now have so much room in our closets and bedrooms with the items we've been able to put down in the basement. What a relief.
If you're struggling with who to call to get rid of the water problems in your basement--struggle no more, give Water Proofing One a call.

We purchased our home August, 2014. Obviously had had some water, but we were told since a backflow had been put in the prior year there had been no issues. June, 2015 rolled around and we had more water in our basement than we could believe. We knew we were going to address fixing up the drainage eventually, but were hoping to wait a few years and that just wasn't going to happen. After weeks of looking, we found

came out and did an estimate. He was EXTREMELY nice, well educated on his services and products and there was no hard sell. In addition to the trenching and the change of sump pit and pumps, we had plastic liner installed on the interior block walls. The walls seeped and actually had some water draining in the wet spring (records breaking wet spring) we had in this area. With the work performed, we shouldn't have any issues with this, but again, it was an option we chose and couldn't be happier. The work took two days and the crew was out for 10-12 hour days. They laid out protective sheeting on our entry ways and steps and took care with the house itself so as not to cause any damage to anything. The crew was very courteous, friendly and worked extremely hard. We were very pleased with the cleanup and I was shocked at how well it looked. Any questions we had were answered and before they left, we were shown around, talked through the process and asked if we had any other questions. We were also encouraged to contact the company should anything else need to be addressed. We really couldn't be happier. We did have another company quote prior to

I was overall satisfied with the jobm The problem started when i contacted them to advise of an issue with installation. It's been almost 2 months and no one has came out to access or address the problem. I sent an additional text msg and still no response. Initially they were very responsive but I'm not sure what going on.

and his crew are all fabulous. Everyone working on our basement for those 2 days were very professional and courteous. They worked quickly and efficiently and left our basement a lot drier and cleaner. They were really careful while installing the drain pipes outside the house, even transplanting some irises. I would highly recommend them.
