did an excellent job from start to finish.
, the estimator was highly knowledgeable and helpful--he was willing to discuss in detail" what was needed and how the repairs would work. The work crew came on the appointed day and worked steadily for two days They took care to do a good job, dealt well with the city inspection process, and finished everything up neatly. Waterproofing work is important, even stressful work to have done on a house--it's important not to cut corners and to go with a company that is serious and thorough. I found
to be such a company. Their estimate was not the cheapest I received but they showed the greatest knowledge about the work and care in getting to the bottom of the problem.

"I scheduled an appointment with
for 7/29/14 at 3-4pm but no one showed up or called. I even called and left a message just asking if someone could call me to" let me know what was going on yet no one returned my call. I took off work early for the appointment so I not only wasted time but also money. Very unprofessional.

in December 2013, we have had a number of periods of significant rainfall in DC. Basement has been 100% dry every time. Pricing: A+ I received 8 different estimates from various providers. The range of work recommended and the prices quoted were all over the map.
was very competitive on price. Timing: A+ Work was scheduled and completed quickly. Team was professional and efficient. Quality of work: A+ My basement is now 100% dry, which is what really matters. The original scope of work for the basement had the drain running along all exterior walls. On the day of the work, they decided that one of the runs to the sump pump was a little too long, so they dug and installed an additional stretch of drain at no cost to me. I was impressed at the attention to detail and the commitment to get things done right the first time. It gives me confidence that
will stand behind the work they do. I used to worry every time rain was in the forecast, but
has given me peace of mind. I absolutely love this provider. Just a wonderful, professional, family-run business. Thank you for giving me my basement back!

It’s easy to do, but forgetting your crawl space can have plenty of negative consequences for the rest of your home from poor air quality to high energy bills.

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 Washington


They did a great job, and we particularly enjoyed working with Zeke. He was very responsive and helped us coordinate with the contractor, which technically was not a part of their service (but made the payment totally worth it). Since their work, we've had no issues.

was very thorough in our initial discussions -- everything that would be done was explained in detail. The contract was explicit as to what would be done. As we have several trees that could be damaged if roots were cut during trench digging, the project design was careful to avoid roots as much as possible. When I needed to change the timing of the job start,
Washington Waterproofing Contractors Provider Name Locked
was very accommodating, and when he needed a small amount of extra time he was careful to keep me fully informed. There was excellent communication throughout the job; he was available anytime I had a question. The supervision was excellent, and the crew was really a hardworking bunch. I can't say enough about them They knew what they were doing and did it very well. While I tend to be hands on with a job of this magnitude, I quickly found that the work was going exactly according to the agreed upon design, and any oversight on my part would be largely superfluous. Digging the trenches around the house required removing quite a bit of shrubbery and then replacing it as the trenches were filled back in. Once the shrubs were replaced you couldn't tell that they had ever been moved. Similarly, two trenches between the house and the drywells at the

required taking up a substantial amount of lawn. This, too, was replaced with no damage, and in a couple of places new sod was brought in. When I look at a business and see excellent results, it is apparent that recruiting and training have been a consistent priority. That was clearly the case here.

We had flooding in our basement, caused by a window leaking.
Washington Waterproofing Contractors Provider Name Locked
was the senior technician that was sent to diagnose the problem and provide an estimate. He showed up on time and was knowledgeable, thoughtful and courteous. Most importantly, he did not try to sell us any services but rather suggested that we fix the problem on our own by adjusting the landscaping around the window. It's rare that we don't feel like we're getting a hard sell and it really impressed us that he advised us against putting a lot of money into it. The next time we have any issues with basement water, this is the company I'll go to first.

conducted a thorough inspection of my deck and basement. He concluded that my water seepage problem was not severe enough to warrant anything beyond a topical solution - i.e., touch up paint. At my request, he prepared an estimate for correcting the rain water leak if the problem became worse. (The solution would be to remove a portion of the deck and install a rubber membrane below the cement and re-laying the flagstone for the deck. ) His estimate came to $2250.

As a property manager, I couldn't be more impressed with
Washington Waterproofing Contractors Provider Name Locked
. They were the third service to provide an estimate for a basement safety egress window and window well. The two previous professional services told me a window well was necessary to make space for a large-enough window to meet safety code. I didn't originally think so but wasn't going to argue with two different pro services. So, at this point, I was merely comparing prices. To my surprise and relief, the
Washington Waterproofing Contractors Provider Name Locked
representative advised that I had just enough space for the safety egress window WITHOUT having to dig a well. Further, the representative recommended I go directly to their preferred custom window manufacturer — Vinyl Lite Window Factory — as BMW wasn't really needed for the job. And Vinyl Lite built us a perfect custom casement window. I used my regular contractor to install it. BMW saved my client well over $2500. I will call
Washington Waterproofing Contractors Provider Name Locked
first when I'm able to deal with another client's damp crawl space later this year. And that will be a much bigger job. Very impressed and pleased with BMW's diligence and integrity. Looking forward to working with them again.

I never managed to get an appointment. I called them one afternoon, and was told that the person I needed to speak to was on the other line, but would call me right back. For planning purposes, I asked them if they would be calling back that afternoon or not. They assured me they would call me back that afternoon, so I waited by my phone, but they didn't call. Three or four days later they finally left me a message. I called them back and spoke to someone, who assured me that they would coordinate with a mold expert and call me back to schedule. I never heard from them again. I have not called them back since I figured if it is so hard to even schedule an appointment, it does not
