"Guys were professional and knew their stuff. Arrived on time,too. Solved my issue in 15 minutes. 'Was completely unprepared for the over $500 bill! My regular electrician was too busy but this was a fire hazard which demanded immediate attention. Wouldn't book with Baker's company again just because of outrageous price."

"I highly recommend Octagon Cleaning and Restoration. We recently purchased a house on the water and discovered that we had a mold issue in our basement. Matt and his crew were professional, informed us what needed to be done and completely eliminated the mold and the musty smell. Matt was very responsive to my texts, answered all my questions and a great representative of Octagon."

Foundation Drain Installation FAQs, answered by experts

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.

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

Installation typically takes 3-7 days, depending on the system and site conditions.

A grinder pump is a major investment for homeowners and business owners alike. Protect this investment by choosing a reliable and reputable contractor to source the pump itself, install it, and outsource any additional work. Research local sewage system contractors ahead of time to ensure they have the appropriate insurance and licensing. You should also perform a fairly thorough online search to get a feel for the company’s professionalism by reading reviews.

Finally, give them a call to discuss the project. A good technician will be more than happy to get into specifics regarding both the installation process and the pricing.

DIY is possible for small systems like French drains. Professional installation ensures proper grading and long-term effectiveness.
