"I posted an initial review on 2/21/19 on a job done on 1/11/19 to fix groundwater from coming into our basement. The drainage system and sump they installed was not collecting all the water that was coming in, as we had leaking from several areas along an uneven rock ledge. I had reached out to our salesperson by phone and email and never heard back, so I was very frustrated. About 3 weeks after I posted the review, I did get a call from Jeff Allen, one of the supervisors. To make a long story short, he sent out one of their waterproofing specialists to look at the problem. We had already hired an independent mason to try to remedy the problem but he had not yet had a chance to do the job. Jeff convinced me that CT Basement systems would do absolutely whatever it took to fix my water problem. I cancelled the independent mason. Danny, a mason from CT Basement Systems came out and used a very ingenious method to divert all the water to the originally installed water guard trough and then to the sump. It is working beautifully!! I think Danny is a genius and I am so impressed and thankful for Jeff's perseverance and kindness in making this happen. I am now a very happy customer."

"A soft wall due to improperly installed gutter by some other entity or homeowner caused water to constantly leak into the wall from the exterior roofline. This soft wall grow moldy and become riddled with pests/bugs. The contractor identified the potential issues, agreed to explore and open the walls and discuss the conditions, made sound recommendations for repair and did exactly what was noted in the repair (replaced a load bearing exterior wall, fixed the sill plate, completed the roof, shingles etc. and closed up the walls on the inside with insulation and sheet rock.). The work was timely, well done, the workers were clean as they did the job and kept the rest of the property clean. The manager of the job David Apel was and is an excellent communicator with phone/email/text and photos of processes and progress. I am going to use this company in my own investment endeavors on other properties and projects given the level of finished work, the timing and especially the level of detailed communication."

"Vincent Police, the owner, started and completed the work as per the schedule. He was on site the majority of the time both supervising his crew and performing the work. He kept me informed on a daily basis and was very helpful explaining the scope of work as it took place for removing the slab in my 2 car garage and pouring a new reinforced slab. The finished product has a professional looking appearance and the crew left a totally cleaned site. I'm very satisfied with the work and i recommend AA Outdoor Services for similar projects.d"

"Someone called back right away and schedule to come to our home at 10am. They were 4 hours late. Two guys, one seem to be professional and knew what he is doing. They checked 3 bathrooms and drain pipe, and suggested I replace the flappers, seal one of the toilets, and put epoxy around the possible crack in one of the drain pipes. The whole job took less than an hour and cost me 620 dollars. I am new a home owner and don't have much experience, and I did not request a quote in writing, but I was told in the beginning that smoke test will cost 550, if it comes to it. They did not do it. I feel they used my inexperience to gain. Not to mention, that the problem of smell remained unfixed and I did not see any changes in how toilets work."

"I selected Schede Plumbing for my conversion from an oil fired heating boiler to a gas boiler. My selection was based on known referrals in the Stamford, CT area from other well satisfied customers. I could not be more pleased, nor rate give enough praise and thanks to Lou Schede and his expert technicians. This was a major project for me and I was very anxious as to how the how conversion would take place. It would require draining the fuel tank, cutting it into manageable pieces and removing it from my basement. The idea of a gas conversion process was a bit scary to me but Lou Schede walked my through was would be involved, assessed what the heating requirement would be for my house, and selected a gas boiler which fit my needs perfectly. It was only two weeks from the time I first contacted Lou until the time the installation took place. My goodness, three Lou Schede trucks and four highly trained, professional and very polite technicians arrived at my house at 8:20 AM and by 3:00 PM my new gas boiler was installed, tested, and providing heat. Amazingly diligent workers worked very hard and did an beautiful installation. It was like a work of art in motion watching them work. The fuel tank was drained, cut up and removed. the oil fill pipes from outside to inside the basement were removed flush with both the interior and exterior walls and were cemented over. Beautiful, as if the pipes were never there. What also impressed me that whenever I had a question for Lou he was always there, immediately. No complicated voice menuing system. You want Lou, you call Lou, and you get Lou...immediately. This was very satisfying to me and he was a real pleasure to deal with. Absolutely top notch in every respect. The price for the installation was remarkably affordable....more that 6 to 8 thousand dollars less then competing firms. Incredible. He even cleaned the chimney, which was required by the city building code, applied for the permit at his expense. This was a thorough, comprehensive one shop job. Other firms required a separate electrician to hook up the thermostat, a separate firm to drain and remove the oil tank, and a separate firm to clean the chimney. Lou and his staff did it all!. One firm and he and his staff did it all. This is amazing. Lastly, he even accepted credit card for payment upon completion of the installation. I can go on and on. I have nothing but the best things to say about Schede Plumbing And Heating. They have my highest recommendation and are now my go to plumbing and HVAC company. Thanks Lou to you and your technicians for thoroughly well done job and an installation experience that was truly a pleasure."

Foundation Drain Installation questions, answered by experts

Most people consider a French drain to be one of the most effective solutions for foundation leaks, but it’s not always a standalone solution. French drains will help keep water away from your foundation to reduce the risk of leaking and structural damage from soil expansion, but depending on your foundation type and location, you might need other systems or techniques—like soil gradation and gutter and leader installation—to resolve the underlying problem.

Methods include interior sealants, exterior excavation and waterproofing membranes, sump pump installation, and vapor barriers for encapsulation. Techniques vary based on the structure and severity of moisture issues.

A sewage ejector pump is necessary if you have any plumbing fixtures, such as a bathroom, laundry room, or sink, located below the level of your home's main sewer line. Standard plumbing relies on gravity to drain wastewater and solid waste into the municipal sewer system or a septic tank. For fixtures below this level, like those in a basement, gravity cannot move the waste upward. The ejector pump provides the force needed to pump the sewage up to the main line. Without one, wastewater from below-ground fixtures would back up, potentially causing a sewage overflow and flooding. If all of your plumbing is on the main floor or higher, gravity is sufficient and an ejector pump is not needed.

Not all window wells have a formal drain, but they all require a method for water to flow away from the window. Some wells are connected to an interior or exterior drain tile, which is the most effective solution. Others rely on a deep layer of gravel or crushed stone that allows water to filter down into the soil.

However, if a window well lacks a proper drainage system, it can lead to basement seepage, costly water damage, mold growth, and potential foundation damage. This is especially true in areas with heavy rainfall or expansive soil.

If your window well doesn't have a drain or is not draining quickly enough, you have a few options. For gravel-based systems, the stone may have compacted and needs to be improved. For a more robust solution, you can hire a plumber or window installer to connect the well to a drainage system. This can also be a DIY project using a shovel or auger.

Yes, many contractors offer warranties for their work. Confirm terms before starting the project.
