"Billy and his crew were an absolutely pleasure to work with. They exceeded my expectation to replace my boiler and hot water heater along with associated piping in record time working in concert with the GC to complete all work in 3 days. The finished work was neat and clean correcting errors with my original installation. All debris was removed each day. He ensured I was satisfied, kept me informed of the progress and what to expect. Upon leaving he made recommendations to have all my air valves replaced in my radiators and encouraged me to call with any questions. I appreciate the care he and his crew took with my home."

"Eddie was great to work with! We had a limited time frame to adhere to town inspections and Eddie and his team knew exactly what we needed and quickly got the job done. The results were great and even the inspector acknowledged the impressive repair. They were able to put a knocked out garage wall back on the foundation and repair the interior dry wall. I would recommend this company for any professional contract work due to their reasonable price, ease to work with and quality of work."

"Im am so happy with the work that was done on my house. Tyler came and gave a very fair estimate on lifting my concrete side entrance stairs to my basement. He explained every step of the process and did exactly what we wanted with no issues. Everything was done to perfection. No damage was done and you cant even tell the stairs ever needed a repair in the first place. I would highly recommend this company and would hire again for any future jobs."

"Torres Contracting helped us with installing a new sidewalk, paved driveway (with specific requirements re design), a side area for the garbage cans and cement for part of a back porch. We hired Tony and Torres Contracting after a lot of due diligence. Tony is a busy man and communicates efficiently by text. He and his daughter addressed all my questions and concerns by phone, email and text. Further the team was excellent- including Juan, Edwin and several others— honest, technically very good and incredibly hard working especially in very hot weather! Torres Contracting was fair on pricing, the project was done in a la efficient manner and the work product is excellent. I am grateful we hired Tony and his company and I highly recommend them as a trustworthy company that does excellent work! Bottom line: Responsive, excellent work, fair price, active communication to understand expectations! 5 stars ⭐️⭐️⭐️⭐️⭐️"

Foundation Drain Installation FAQs, answered by experts

Test regularly, clean the pump, and inspect the discharge line to ensure efficient operation.

Yes, professionals ensure proper grading and drainage to prevent water pooling.

Due to the nature of basements, some level of waterproofing is necessary to prevent water from seeping in and causing damage. Some definitive signs that your basement needs waterproofing measures or needs existing waterproofing measures need to be updated include:

  • Water in your basement, including damp walls or puddles on the floor

  • Mold spots in your basement

  • Musty smells or odors

  • Warped doors or walls

  • Cracks in walls

  • Insect issues, such as cockroaches and termites

Yes, you can add a battery to your existing sump pump. There are batteries available that can be plugged into your existing system; however, most battery backups come as a complete system and act as a replacement for your existing sump pump.

Yes, the air from a damp basement can travel up into your living area through a process called the stack effect, so moisture, mold spores, and other debris in your basement air can all decrease your indoor air quality on your main floors. Additionally, damp basements can promote the rotting of building materials, which can damage flooring, insulation, and framing on your first floor in addition to materials in the basement.
