Sump Pump or Interior Foundation Drains Installation
$1,200,000
The job inside was done. However the drainage put in outside has turned our yard into a swimming pool. We once had a pipe draining to the creek and this was a perfect solution to the rains/weather. These guys came in and put a round small cylinder well. Water pumps up into our yard turning it into a swamp. Called them to come and see the problem they created. Their response $2900 to fix THEIR DAMAGE. I WOULD NEVER RECCOMEND THIS COMPANY!!
Response from

"Hi Mike, We appreciate your feedback and are sorry to hear you're dissatisfied with our services. Your primary reason for having us out was to resolve water intrusion in your basement, so our main objective was to manage the water in that area via our dual pressure relief system to create a safe, dry space. Per industry standards, the water collected by the system must be discharged somewhere. In your case, we directed it to a pop-up emitter approximately 20 feet from the house which is a common and effective method in most situations. However, groundwater conditions and water tables vary greatly from property to property, so it?s not possible to predict how much water will discharge over time or how well the yard will absorb it. When you expressed concern that the yard wasn?t handling the discharged water, we sent a technician to assess the situation and explore alternative options. Seeing the creek nearby, he recommended extending the discharge line to empty into it. However, because the creek is roughly 100 feet away, this solution would require additional piping/fittings and a significant amount of labor to complete, which is why a separate estimate was provided. Had this extension been completed during the original installation, it still would have incurred an additional cost, and if the pumps weren?t discharging as frequently, it may have been an unnecessary expense at that time. We're always willing to work with our customers to find solutions and we regret that you're unhappy with how things turned out. Please feel free to reach out if you'd like to continue the conversation."

I can not recommend this company to anyone. The quality of the job I received for the price I paid was absolutely poor and disgraceful. The job was issued to a sub contractor who saw a get rich quick scenario and rushed to blow the job out in 1 day. A job which should have been 2 to 2 1/2 days for a proper quality job. While the guys them selves were pleasant the quality of what was done was poor and not what was discussed. They were to install a water proofing system in 3 levels of my basement. Install 3 sump pumps and slab a crawl space with a smooth finished floor. They did not use proper dust suppression. They came in Jack hammered up the floor sending dust every where and through all levels of my home. Simply wetting the floor prior to would have helped immensely. There was no time or care taken to ensure the clean outs were flush with the new floor, some were sunk in, raised, not level. All had concrete in them and were not cleaned up at the end, the spilled concrete was just left there. The waffle board (drain board) was not installed uniformly and neatly in all areas in some places its not tucked tightly into the corners or level on the walls. They drilled weep holes all the block to allow for water drainage but neglected to clean any of the dust/debris away from the holes to allow the water to properly drain. The sump pump wells were not installed with care or even cleaned out after they were done (in fact after a 2nd trip to do so I was lied to and told they were cleaned out, in which they weren't) so now a 3rd trip. The electrical ports were not installed with any care as to alignment or placement. The crawl space floor which was to be slabbed, was supposed to be smooth and flush with the existing floor that was already in place. What i got was a rush job that had trowel marks left behind. The floor is unlevel and uneven and will never be what is was supposed to be. The cement they mixed in mixers on site was not mixed correctly (they added to much sand to make it stretch and cut cost on cement) which resulted in a gritty sandy floor (so now 3rd trip trying to vacuum it and apply a hardener). They left a wood form in my door way and never planed on returning to remove it. It was going to be left for me to figure out. They neglected to install the system in @ 3 feet section of my floor (where it was diagramed to be installed) and I now have water in what was supposed to be a water free basement. (so I guess here we go for a 4th trip out) How much of my time do I have to waste sitting home for them. The clean up afterwards was basic and almost non existent. Basic sweep up and run down the road while I'm left with dust covering my entire basement and all the contents of my garage. Hand prints on my walls, mud on my door jams, mud and concrete on my over head water lines in my crawl space (as if they used them for hand lines). Sand and concrete stains on my driveway and stairs. Concrete debris left outside on the patio from drilling a hole for the drain pipe. My Lawn Burned form the concrete spilling off there pieces of tarp (yes small pieces put together to try and make a big enough area). They did not have any equipment to do a proper clean up and never planed to. No shop vacs to clean up the dust, no rags and cleaners to wipe stuff down, no blowers to clean the driveway. So far they have been back out to my home 3 times after the initial install to try and patch and rectify what should have been done right in the first place and will never be done right, and still looking at a 4th call back and who knows how many more. I paid more than the competitors estimates thinking I was going to get a "QUILITY" job, and better quality materials, so far the job "QUALITY" is extremely poor. As far as material quality that's still to be decided. For $35,000 I should not have to go through any of this or clean up there mess. S...

"Todd, we?re very sorry for the issues that you?ve experienced. The work was originally anticipated to take longer, but as you know, we had a crew of approximately 30 guys completing every aspect of the job simultaneously and at the time, you seemed pleased with this as you wrote that the crew was ?efficient and quick? on the post-job survey. While we admit there were some unanticipated issues, we have stood by our work and have returned to address everything that we could thus far. We understand that there is further discontent and have been working with you to come up with an amicable solution; however, the disputed payment has caused a significant delay in reaching any kind of resolution. We remain committed to working with you and hope to resolve these issues and find a fair outcome for both parties."

Concrete Foundation Repair
Yes, I recommend this pro
Brett Strough and Mac M. came out to inspect the 2 foundation cracks. one was visible one was not as I have one section of the basement finished. He explained in detail how the repair was to be done and I agreed to the process he explained to me. The work was scheduled and completed on time. The 2 workers he sent were very knowledgeable and worked in a timely manner. When the job was completed I was very satisfied and even gave them a 50.00 tip. Although we have not had much rain I am confident our water problem is resolved

We had an amazing experience with BWS -- not something you can always say when it comes to contractors! Aaron spent a lot of time with us, reviewing what he found in our basement, answering all of our questions, and was extremely helpful (including encouraging us to talk with other companies -- confident that we would return). After researching a few companies, we found their process and product to be superior and without taking any shortcuts. Aaron's crew, headed up by Doug, exceeded our expectations! They had estimated the job would take two days -- and they completed in only one. The crew worked together -- efficiently and pleasantly -- like a well-honed team. They left everything clean and in great shape -- taking great care to cover up and protect furnishings. The new sump pump is so quiet -- you can't even tell it's running. We feel confident that we have installed a waterproofing system that will protect our finished basement for life and greatly appreciate the professionalism of all involved. Aaron continues to be available to answer follow-up questions flooring contractors have posed as we now enter the phase of replacing flooring. We feel we have a trustworthy partner in solving our basement problem and restoring it back for our family's use. I can't say enough about how great our experience was from beginning to end.

Thanks again for choosing BWS to protect your home!"

This is the second time I am using the company. They first did a great job on my rental property that is 150+ years old. For this review, Anthony, Carlos and his crew took care of my primary house that is roughly 80 years old. Carlos and crew showed up a bit late due to traffic, apologized profusely for the delay, which I was fine with since it was out of their control. The crew stayed late and finished the job in one day. The work was nicely done, the worksite was kept clean and the crew were very organized. I would highly recommend them.

They messed up my basement window, left water all over the basement floor, left a bucket with rocks and water in it, and failed to mention until the end that we would need to hire an electrician to install a new outlet to plug in the device they installed.

The product quality was excellent. The outside work completed was not performed with experienced personnel and it showed. It would be best to make sure the team doing the work understands the procedures needed to make the job go smoothly with a good result the first time around.

The inspection seemed to be pretty accurate but in the end I was only left with a paper which had very few details of the job that needs to be done. I was told that i would have gotten a more fetuses report via email and, even if if chased them for two days with texts, calls and email, I never received anything.

"Giovanni, we are sorry to hear of your experience with our company. We leave proposal reports detailing what we would be completing with our free estimates when we visit homeowner's properties. A representative from our office spoke with you when you called helped to clear up the confusion regarding the proposal report."

Basement waterproofing specialist were a great crew. The inspectors, Mike and Vinny explained and showed me the materials to be used. The crew, came early and started right away. When finished, they cleaned up and left everything as it was. Sebastian the foreman, walked me through what was done, and asked if I had any questions. Very happy with the whole project. NO more water!!!
