"Had a leak in front yard, on my main water line, hoping it was a simple leak turned out to be a major repair due to the pipe being old and not fixable. Chris was my technician, explained what was going on and took on the tremendous work of replacing my front line. He was going to make sure that it would get done so I would have water that day. He was very professional and did an awesome job, really appreciated everything he did, so I wouldn't be without water or take another day off from work. Thank you Chris. Mary Markins"

"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."

"On a Sunday, the stand pipe that drains the washing machine overflowed, we checked Angie's List and called Custom Plumbing and they sent someone within 20 minutes to cable the line, in the rain. A few days later, a camera was used to find the damaged sewer pipe and with ground radar the area was located under the foundation. Containment was set up and the crew jackhammered the foundation and dug down two feet to replaced the damaged pipe. The exavation was filled and concrete poured. The entire system was hydro-jetted. Everyone was very efficient and professional, explaining every step of the task. Thankfully, Custom Plumbing prepared the invoice for our homeowners insurance reimbursement for half the cost. This is a great company!"

"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

Mold and other fungi love moisture, so the best way to prevent mold growth after water damage is to remove as much moisture as possible. First, find the source of the water or moisture, such as a leak or clogged gutters, and correct the problem. Next, remove standing water, vacuum up puddles with a shop vacuum, and run blower fans and dehumidifiers for 24 to 72 hours. Once you've removed all traces of moisture, disinfect the area using either vinegar or bleach to kill any remaining mold spores.

A leak under your foundation from a water supply line or sewage line is likely to lead to water pooling on certain areas of your property during rainfall, abnormally fast-growing or green grass in certain sections of your lawn, and differential settlement of your foundation, which can result in large foundation cracks, windows and doors failing to operate properly, a wavy or sloping roofline, or damages or irregularities in your interior walls, including cracks and bulging. If it’s a plumbing line embedded in your slab, you’ll also likely notice above-average water bills.

If a crawl space isn’t vented, there can be moisture buildup, which can lead to mold damage, easily destroying the foundation of your home. A closed-off crawl space can trap heat, which can be useful in the winter, but can also trap dangerous gases and prevent clean air from entering the home through the floorboards.

Rigid foam board insulation is one of the safest insulation materials for basement walls. The panels offer a moisture barrier to prevent mold and mildew build-up. At the same time, this material is also fire-resistant, so you don’t have to worry as much about a fire breaking out as you would with spray foam insulation. 

Basements are commonly converted into game rooms. The potential challenges you may run into include controlling moisture, working with low ceilings, limited natural light, and the need for additional electrical or HVAC work. Addressing these issues can add to the total cost, but it ensures a comfortable and functional space.
