"Great. I have an old house built in 1905 with stone foundation walls and another part with cinderblock walls. After learning the difference between their WaterGuard and crack repairs and what other companies do, I chose them because their upgraded products and ideas really made sense and I was willing to pay a few bucks more for better stuff and a good company. They ended up being the middle guy in cost, but way better quality I think."

"Had a good experience overall. They had an opening in the schedule so were able to start quickly. Property had some plumbing buried in the floor that the crew had to work around and it was all done without any issues. Crew was professional and easy to work with. Haven't had any water issues since the drain and sump were installed several months ago--despite several big rains."

"I was having some issues with water coming into the basement through the foundation and walls during rainy weather. Not flooding, or even shop vac-able volumes, just enough to be annoying and require mopping. Dominic and his crew were here today to install an under-floor drainage system and a new sump pump. I was dreading the demo (I have a concrete floor) and the mess involved, but these guys came prepared for everything! They used dust abatement measures to protect all my basement-stored items, and they removed and hauled all the debris away when finished with the excavation. What really impressed me was the concrete restoration upon completion. I've previously had a sewer line replaced through the basement floor, and the contractor really "botched" the floor repair. I can't describe how different this experience was! The concrete installed today is immaculate! Dominic takes pride in his work and with good reason! The new concrete is perfect! I am thrilled!"

"Dan and his team were both efficient and knowledgeable. They installed a french drain sump pump and made repairs to our footings at our residence three years ago and not a drop of water since then! Thats why we recommended them for the work we recently did at our church. The crew installed a complete system with two sumps and pumps in two days! From start to finish they did an outstanding job at competitive prices using quality materials. The clean up was amazing as well! Except for the new concrete, you would never know all of the work that was involved! I highly recommend Dan and the Basement Guruâ s for all of your water infiltration/foundation needs!!! You wont be disappointed!!!"

"Excellent work! 2.5 hours start to finish, replaced poly line with copper, trench was filled back in and I barely notice that it was dug (sod put back and all). Foundation was sealed back up perfectly. Really friendly, courteous, and knowledgeable technicians. Thank you DPP!!!"

"We started having issues with our foundation settling. We searched on line for foundation repair companies in our area. We decided to get 3 estimates. Because of their great reviews we called AFS first. Robert Stringfield showed up to explain our issues and gave us an estimate for the job needed. First of all Robert was very polite, professional and knowledgeable about foundation repair. He spent a great deal of time measuring and surveying the issues, causing our foundation to settle. He also found some mold that we were unaware of. He also observed some large cracks in our concrete driveway. After he completed his through inspection, he proceeded to show us the problems we were having by using pictures on his laptop. He then went into great detail explaining how AFS would take care of all of our issues, foundation, mold and driveway. He presented three options that we could choose from. 1. support to stabilize foundation. 2. support to stabilize foundation and install drain system with sump pump. 3. support to stabilize foundation and install drain system with sump pump and totally encapsulate the crawlspace. We chose the third option and decided to have our driveway repaired. AFS does offer low cost financing and a discount for package deals. Also included is a life time warranty, that covers a parts and labor, that is transferable should you sell your house. We also got estimates from RamJack and American Foundation Repair, but because of Robert and the great reviews AFS had, we chose them to do our job. The workers showed up on time and completed our job in five days. Everybody we dealt with at AFS was great! We would highly recommend AFS to get your job done. It was a very expensive job, but gave us the security of knowing it was done right. A rule I have learned over the years: Good work is not cheap. Cheap work is not good."

"I reached out on Anji for recommendations for plumbers and DPP called within minutes Ron Guderjahn came out to fix a slow drain for us. He explained everything, gave us several options on how he could do the repair with different price points, and was extremely nice."

"We initially retained Martin to redo the kitchen, and we chose him because of price, flexibility and lack of hassle. Martin did all the carpentry work for the kitchen remodel, including plumbing the walls and fixing a termite-damaged floor beam, and he also did all the plumbing work. Work was done very well. Because of the good work, we then asked Martin to remodel a bathroom, and that was done very well, and included tile installation, new piping etc. That went very well. The prior work held out, and so we asked Martin to replace the roof. That roof work was done very well also. On the first day, Martin had about 10 people working on the shingle-part of the roof work to make sure that work was done before rains came. A following day his people did the flat part of the roof. We have now had some heavy rains, and I checked and everything is fine. No damage to the guttering system. So, very happy and would recommend."

Foundation Drain Installation FAQs, answered by experts

The least expensive basement waterproofing methods include grading soil away from your home, installing downspout extenders on your gutter system, and applying a waterproof paint on the interior of the foundation walls. Installing a French drain is a relatively inexpensive method if you do the work yourself, although it’s labor-intensive and can be challenging to install properly.

Grinder pumps alone cost $300 on average. The average cost to install a new grinder pump is between $2,000 and $4,000, including the pump and labor. This price can also change based on the exact type of grinder pump you choose, labor costs in your area, and the power system your home currently has.

If the time has come to install a French drain in your yard, basement, or crawl space, there's a solid chance you've been battling water damage—or the threat of water damage—around these areas. Thankfully, proper drainage should allow you to redesign these areas of your home without the fear of being inundated during the next storm. If you've had to remove a portion of your lawn for an exterior French or curtain drain, consider reseeding your lawn to patch up the spot. You can also take this opportunity to enhance your foundation waterproofing methods or even start thinking about finishing your basement .

A small sump pump running infrequently uses an average of 10 kilowatt-hours (kWh) of electricity per month. The average cost for electricity is $0.171 per kWh. The size and use frequency affect how much electricity it uses. Sump pumps average one-third to one horsepower (hp) motors. One hp is equal to 745.7 watts. Watts multiplied by the time your pump is running divided by 1,000 equals your average kWh. Multiply kWh by your average cost of electricity. In areas with high rain or a marsh basin, the average cost can be as high as $15-$25 a month.

Walkout basements cost more than other kinds of basements, and can also increase your risk of leaks as well as a loss of insulation, leading to higher heating and cooling costs. Improperly installed walkout basements may lead to structural issues with your foundation, so ensure you’re working with a contractor who has extensive experience with this kind of basement.
