Foundation or Basement Waterproofing

From my initial inquiry to completion of the project, and even a few calls after completion, we found Poseidon to be exceptionally responsive, punctual, professional and experienced. We highly recommend them to anyone needing basement work done.

Foundation or Basement Waterproofing

The crew that put in my drain were very professional and punctual, even as my house was a far drive for them. Would recommend

We were in the middle of renovating an investment property and got the worst news possible - there's too much water in the basement. This was far too large of a project for us to handle ourselves, and absolutely not something you want to mess around with from a liability standpoint as a seller. So we had to bite-the-bullet and have Poseidon come give us an estimate. From first contact with Dave for the estimate, we knew we called the right place. He even "sold" us on having them install the white, vinyl walls to cover the old, decrepit cement block in the basement (looks GREAT, by the way; highly recommend this). The team of men that came on the first day were SUPER courteous and left the place CLEANER THAN THEY FOUND IT. This is unheard of in my experience with contractors. Everything was broom-swept; no Gatorade bottles lying around or cigarette butts. Extremely hard workers. All the drainage, concrete work and sump-pump installation was done in one day!! The second day two different men came to install the walls and were just as courteous as the workers the prior day. They arrived around 8:30AM and didn't leave until almost 7PM and their drive was about an hour and a half home, so I have to commend them for the long hours they put into working on our job. I was around more often the second day and would stop by from time to time. Again, just genuinely courteous and happy to do the job well. I am positive if I said I would have preferred purple walls, those gentlemen would have ran out and bought purple paint and made those walls purple just to make me happy. I eventually asked them - What gives? Why do you work such long hours? And without missing a beat, they both replied: "Because we couldn't ask for a better job; we love what we do; couldn't ask for a nicer owner; he takes care of us..." You don't hear that too often from laborers. From those statements alone, it's clear that integrity runs deep within this company. OH - and the work was great too :) Hoping for a quick sale on this property now! Poseidon's lifetime warranty should make it that much easier. We'll definitely continue using Poseidon on future jobs.

I have been using Poseidon since August of 2015. They have done several projects for me. I have been more then pleased and have developed a excellent professional relationship with them. The work is always reviewed, AND REQUIRES YOU TO BE SATISFIED. I suffered with water in my basement for 7 years as long as i owned my house, I had several options on what to do. Julie the office manager contacted me, with No pressure to buy, had Ben, the specialist come out we sat down, again No pressure, we sat for a few hours discussed needs, I received and invaluable education. We scheduled, the crew they were here for 2 days, you don't even know the are here, then when complete they explained everything what they had done, with in a few days Ben came back out to inspect and make sure I was pleased. I HIGHLY RECOMMEND POSEIDON. Bryan Treese, Northern Cambria, Pa

The work that I had done by Poseidon Waterproofing was to have their system installed into my basement because I had constant problems with my basement flooding. I would, and have recommended Poseidon to anyone. They do top notch work, are punctual, and all of their staff are courteous, helpful, and extremely efficient in all that they do. I could not be more pleased than I am with Poseidon. It is truly wonderful to have a dry basement!
