"John and his team (Sal and Billy are just some of the team members) turned our dark, musty basement into a masterpiece! What once looked like a dungeon is now a bright, cozy space where I actually want to spend time. I thought the only thing our basement would ever be good for was hiding holiday decorations and junk, but now it’s a whole new level of livable. John made the process so easy and stress-free, always ready with a solution to every challenge. His crew worked with such precision that even the drywall looks like it belongs in a museum. Highly recommend, if you're thinking of remodeling your basement, just call this company. Your basement will thank you!"

Basement Leak Repair questions, answered by experts

Trench drains have a bit of a reputation as being difficult to clean, so if there’s a massive rainstorm that leads to a lot of debris and gunk getting stuck in the drain, you’ll spend extra time cleaning it out. Plus, you definitely need to regularly clean the drain, heavy rainstorms or not, to keep it in good condition, adding an extra step to your cleaning to-do list.

Signs include persistent dampness, mold or mildew presence, musty odors, and visible water stains. If any of these occur, it is advisable to contact a professional for an inspection.

If you’ll be digging up your floor to get access to your pipes when putting in a sewer backflow preventer, this would also be a good time to take care of any other plumbing issues or renovations. For example, you could install additional pipes for a basement bathroom. Since the floor will be sealed over with concrete when you’re done, now’s a good time to take care of those bigger tasks.

To ensure your basement walls are waterproof, it's crucial to address any existing moisture issues before finishing. Inspect for signs of water seepage, such as dampness or discoloration, and repair any leaks or cracks. Install a vapor barrier to prevent moisture from penetrating the walls, and consider waterproofing paints or coatings.

Proper drainage systems, such as interior or exterior waterproofing, can also be beneficial.

You may have to dig out drain valves if they are buried under dirt. This method isn’t ideal, and it increases the chance of clogs and damage. Ideally, a drip irrigation system buries drain valves in a gravel pocket so they are easier to access and better-protected. If you have trouble accessing drain valves, hire a sprinkler professional to find them safely and efficiently.
