"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."

"Nixon repaired two very extensive cracks in our Corian sink that others did not want to deal with. He also fixed more problems that we were not aware of but could readily see when he showed them to us. Nixon saved us the cost of replacing the whole Corian kitchen counter top and potentially future large water damage. He is easy to deal with and provides prompt service."

"They arrived on time, and assessed the issue. I needed to replace my original sewer pipe and the lead connector to the toilet—both located in our crawl space. They scheduled a day to do the work. It took 1/2 day to update the sewer pipe to PVC. They were clean, courteous, and knowledgeable. Every is working great."

"I spoke to the company owner Lou Schede on Sunday and we scheduled one of his service technicians to meet me on Monday. I informed him I would like to receive at least one hour notification prior to the person arriving for the appointment. The next day I received a text from the service technician named Kelroy. He later called me an hour in advance of arriving for the service call as Lou had committed to do. Kelroy and his helper went on to diagnose and repair the furnace issue in timely manner. I appreciate, he was making efforts to repair the furnace on this first service visit rather than replace unneeded parts or require an additional (more costly) follow up service visit."

FAQs for sump pump repair or replace projects in Stamford, CT

Sump pumps last about 10 years with proper maintenance and prompt repairs. Several factors can influence your sump pump’s lifespan, such as usage, environmental conditions, and installation. Premium sump pumps with heavy-duty motors and quality components tend to last longer than lower-cost models. Pedestal sump pumps usually last longer than submersible models since they’re not constantly exposed to water.

A basement French drain is a drainage system installed in basements or around a building’s foundation to redirect water and prevent flooding. This system features a trench with a perforated pipe that catches and transports water away. These systems can crack, freeze, or clog, potentially resulting in flooding or strain on your sump pump.

You can use a sump pump in your yard to minimize pooling water and landscape damage, but it’s best used in conjunction with other drainage systems. This can include French drains, trench drains, underground downspouts, and other equipment. Proper lawn care, such as soil aeration and native plants, also aids with drainage.
