"John and his crew, consisting of two sons and his nephew did a fabulous job repairing several tiles on my rear patio and sealing it. They moved my heavy patio furniture off of it, put it on a tarp and covered it all up. Came back the next day and replaced everything as it was. They were all very nice, extremely courteous to my wife and myself. I highly recommend them and will certainly use them again."

"I had water near my kitchen sink. Our first quote was almost $4000 as they misdiagnosed the problem. They came out and did a much more thorough job taking a look at the sink, and all the appliances. They found a leak in the dishwasher that didn’t require tearing through our floor. They saved me a lot of money and head ache. Acted professionally and will be the only team I’ll call going forward."

"Glenn was very professional and went out of his way to please us.  The installation of the RO and water conditioner went really well.  The installers went right to work and were friendly.  Right away we noticed such a difference in the water.  It's amazing!  We couldn't be happier with what we purchased!"

"The serviceman was quickly able to diagnose the problem (when a previous serviceman from another company was not). He ordered the materials he needed and returned 4 days later to complete the job.  He explained the workings of a water softener and RO system so that I could understand it.  He was neat about his work and I was very satisfied with the job he did.

"Plumbing Masters is my #1 go to for all things water in my home! They are a professional, down to earth, and honest company! It is hard to find someone you trust in this business, as we all know about being oversold on things we might not really need.... Not with Plumbing Masters. They are honest and will do their best to save you money, but fix your problem! I highly recommend them! Also, super quick response time... I did not have to wait days without being able to use my shower! One last thing that sets them apart from their competition... they are "real" people. Check out their Instagram page to meet the owner and some of their employees!"

Basement Waterproofing FAQs, answered by experts

Ideal humidity conditions generally range from 30% to 50%, with 45% considered optimal humidity for most homes. If your humidity levels drop below that range, you can turn your dehumidifier off. Additionally, suppose the temperature where the dehumidifier is installed falls below 60 degrees Fahrenheit. In that case, it's best to turn it off and unplug it since cooler temperatures can cause the unit's coils to freeze.

Unfortunately, mold can grow pretty much anywhere, on any kind of surface. However, you’re most likely to see it in damp areas like basements or bathrooms, as well as anywhere there has been a water leak. Consult a local mold specialist to determine if certain areas of your home are prone to mold based on climate and other factors.

Crawl spaces are prone to issues caused by excess humidity and improper ventilation, but that doesn’t mean you should avoid buying a house with a crawl space. A home that is encapsulated and well-maintained shouldn’t have any more issues than a slab or basement home.

Mold growth is just one common sign of excess moisture in the bathroom. You may also see the paint in the room start to peel away from the walls, or that the walls remain wet for some time after you bathe.

Condensation on the windows is another sign that your bathroom has a potential moisture problem. The room itself may start to smell like mildew.

Anything having to do with the structure of your home, such as raising the ceiling, is usually the most expensive part of finishing a basement. Another project component that could be a surprisingly high expense is adding an exterior entrance. 

The cost of a walkout basement can be anywhere from $5,000 to $35,000.
