Editorial Standards

Flood Mitigators is a family-owned drainage contractor on Pagewood Lane in Houston, built around one problem: water that will not leave a property after a heavy rain. Houston sits on flat clay that drains slowly and sits beside bayous that spill over, so most of the company's work is exterior. Services include French drains, sump pump installation, channel drains, catch basins, culvert work and hydro jetting, with a 3 year parts and labor limited warranty on new systems. It holds 4.8 from 56 Google reviews, read October 21, 2026. The site does not list a founding year, owners or insurance, so ask for those before signing.

  • Best for yard and foundation-edge flooding on slab homes
  • 3 year parts and labor limited warranty on new systems, with two maintenance visits per year
  • The website lists no state plumbing licence number, insurance or founding year, so ask for proof before booking.

Editorial Review

Our Take on Flood Mitigators

Flood Mitigators is a drainage specialist rather than a full basement waterproofer, and that is the right fit for most Houston slab homes. Reviewers consistently praise John and Manny for clear explanations and fast follow-up. The missing licence and insurance details on its website are the main gap, so verify them before you sign.

    My mom's backyard has a pretty bad pooling problem. Anytime it rains, there are puddles all over. We weren't too worried about it until the water started pooling closer to the foundation. I started researching for experts who could give us advice. I found Flood Mitigators while researching and booked a virtual consultation. I was a bit worried at first, but Manny was incredibly helpful and detailed with his explanations. Thank you Flood Mitigators!!!

    Flood Mitigators are top tier, even the weather can't stop them! They pushed through stormy days and intense heat to finish my installation. Their work ethic is 10x better than other contractors I have hired in the past. They’re knowledgeable, efficient, and were a breeze to work with. Thank you Flood Mitigators!

    When our home flooded, we felt completely overwhelmed, but luckily we found Flood Mitigators and its owner, Manny as a reliable lifeline. What impressed us the most was their integrity and transparency of what needed to get done to solve our problem. They gave us a realistic assessment right away, explained every step of the mitigation process and never tried to upsell us more than what was needed. The team was punctual, professional and got all of the details of our project scope done in short order. It’s rare to find a contractor this trustworthy, highly recommended to anyone who is looking for true flooding expertise

    Manny and the Flood Mitigators team are truly experts at their craft. They listened patiently, and helped me understand my flood risk and go over effective solutions to my specific problem. They thought of things that others did not, asked the right questions to address the problem at the root cause, and provided me with sensible guidance planning out my drainage system. Their cautious and mindful approach is unmatched by other competitors I spoke with; if you are looking for permanence, resiliency and performance, look no further than this team!

    I hired Flood Mitigators for a French drain installation along the side of my house and came away impressed enough that I brought them back for another larger commercial drainage system. Both jobs were done right! However, what impressed me the most was how they great you. I work in healthcare, so bedside manners is something I can’t help but pick up on, and theirs is outstanding. They were patient with every question and concern I had, and never once made me feel like I was taking up their time. They followed up on items we had discussed instead of leaving me to chase them. They were reachable when I needed them, including a call I made at 1 am on a weekend that they actually picked up. There was sincerity behind all of it. The residential project was detailed and clean. The commercial project had far more moving parts, and they scaled up without losing an ounce of that same care and communication. That is rare to find. If you need a drainage contractor in Houston, call these guys.

Company Background

About Flood Mitigators

Houston gets its flooding two ways: bayous that overtop in a big storm, and flat clay yards that hold water against slab foundations long after the rain stops. Flood Mitigators, a family-owned drainage contractor at 8614 Pagewood Ln in the Mid West area, works on both problems. The company says it started after Hurricane Harvey in 2017 and serves Greater Houston, but it publishes no founding year.

The services are mostly exterior and below grade: French drains, channel drains, catch basins, PVC drain lines, downspout tie-ins and sump pumps, plus culvert work, hydro jetting and root re-routing. Its sump systems use dual switch pumps with battery backup, and the French drains keep working by gravity, at reduced capacity, if power fails. The site lists foundation drainage but does not describe interior basement sealing or crawl space work, so pier and beam owners with a wet crawl space should ask what is offered.

The process starts with a flood risk assessment, virtual or on site, then an itemized proposal, installation and testing. New systems carry a 3 year parts and labor limited warranty with two maintenance visits per year, and the site says consultations and estimates are free.

The company holds 4.8 from 56 Google reviews, read October 21, 2026. Reviewers name John and Manny repeatedly. One homeowner praised how carefully the crew protected the property while installing subsoil drainage, and another said Manny took time to find the root cause of a flooding problem. The reviews we read were all five star, and the website shows placeholder counters, so lean on a written estimate rather than the marketing copy.

It suits homeowners with standing water in the yard, pooling at a porch or slab edge, or a failing sump setup. It suits less well anyone needing interior basement waterproofing or structural repair. Texas has no state waterproofing licence, though sump pump and drain line work falls under the Texas State Board of Plumbing Examiners (tsbpe.texas.gov) and the City of Houston permits. Before booking, ask who holds the plumbing licence, request proof of insurance, confirm who pulls permits and get the warranty in writing.

Flood Mitigators FAQs

  • Is Flood Mitigators licensed in Houston?

    The Flood Mitigators website does not list a licence number, so ask for it directly. Texas has no state waterproofing licence, but sump pump and drain line work falls under the Texas State Board of Plumbing Examiners (tsbpe.texas.gov), and the City of Houston issues permits. Check any plumber's licence on the TSBPE lookup and ask for current proof of insurance. The site shows logos for the Texas Floodplain Management Association, Texas 811 and NDS Certified, but states no insurance details.

  • Does Flood Mitigators offer emergency or weekend service in Houston?

    The company advertises a live helpline and same day dispatch on weekdays. Google lists hours as Monday to Friday, 6 AM to 8 PM, with Saturday and Sunday closed, while the website says weekdays 6 AM to 6 PM and weekends by appointment only. It also says it follows public works first responder frameworks for post-storm response. Call 281-849-1082 to confirm availability after a storm.

  • What warranty does Flood Mitigators give and where does it work?

    New systems carry a 3 year parts and labor limited warranty, and the site says two maintenance visits are included each year. The company serves Greater Houston and the surrounding metro area. The site says free consultations and estimates are available, and it does not state financing options, so ask about payment terms when you book.

  • Is Flood Mitigators licensed and insured?

    We checked 0 of 3 credentials against the issuing authority. Verified items carry the date we checked; reported items are what the business told us and we could not independently confirm.

  • What areas does Flood Mitigators serve?

    Houston. Coverage is as the business describes it, cross-checked against where its recent documented work is. Confirm your address before scheduling, particularly at the edge of a service area.

  • Does Flood Mitigators offer emergency service?

    Yes, the company lists emergency availability. Response time depends on demand, and after a storm every company in the market is stretched.

  • What warranty do they offer?

    3 year parts and labor limited warranty on new systems, with two maintenance visits per year. There are usually two warranties on a job: the manufacturer covers materials, the contractor covers workmanship. Get both in writing and check whether the workmanship coverage transfers if you sell.

  • How was this profile built?

    Credentials come from issuing authorities, ratings from the company's Google Business Profile with the date we read them, and the editorial take from our own review of estimates, warranty documents and public feedback. Anything the business told us is labelled as reported.

  • Can a business pay to improve its profile?

    A business can subscribe to manage its own listing details, and it can buy a labelled sponsored placement. Neither changes a ranking position or the editorial assessment on this page.
