"Honestly, I have never had such a positive experience with a contractor. they showed up on time, were friendly, polite, courteous, clean and efficient. In a single day they installed the entire system and left the place clean (within reason). This included jack hammering more than 30 feet of concrete floor and complete water ejection. Unbelievable. They will never be the cheap solution, but they are worth it!"

"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

Basement toilets don’t always need a pump. However, it is the most common setup because plumbing systems use gravity to move waste away from the home. Basement toilets often sit below the home’s main sewage system, and installing a sewage ejector pump pushes the wastewater and sewage up to the main sewer line. Alternatively, you can use an upflush or macerator toilet that breaks down the waste and pushes it straight to the main sewer line rather than via a sewer line from the bathroom.

Submersible and pedestal sump pumps are two popular types of sump pumps. Submersible models are covered by water in a sump pit, which helps keep the motor cooler and quieter. Pedestal sump pumps stick out of the sump pit, so the motor stays dry and is easier to access. Submersible sump pumps are the pricier option, but they also have longer life spans.

Yes, you can install a sump pump yourself. By following the steps above, you can have a sump pump installed in 24 hours. You will have to use some advanced tools and techniques, so if you feel uneasy about taking it on yourself, it’s best to hire a professional.

Heavy rain can affect a leach field because the extra rain can cause the groundwater level to rise. This leads the soil around the leach field to become saturated with rainwater, so it’s no longer able to take in effluent from the leach lines for final treatment. Heavy rainfall can cause the leach field to flood.

The cost of basement waterproofing is $4,950 for the average homeowner. However, you could end up paying between $600 and $14,000, depending on factors like basement size, waterproofing method, and the region you live in. 

If you live in an area with heavy rainfall, you might be paying more for waterproofing than if you lived somewhere drier since waterproofing contractors would be in high demand. Likewise, a 500-foot basement costs between $2,500 and $5,000 to waterproof, but that price rises significantly for a larger basement.
