"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."

"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!"

"After flushing the toilet, my sewer backed up into the shower. I called Thornton Plumbing from the Angie's List magazine. Kris arrived promptly. He unclogged the main line explaining to me exactly what he was doing and why he was accessing it from the roof. I had a similar problem 5 years previously, but the rotor rooter person who came was not that thorough or neat. Kris explained to me how the plumbing was probably installed under the house. Kris impressed me with his thoroughness so I asked him questions about my tankless water heater. Kris said it should be cleaned at least once or twice a year. It was installed two years ago and I had never had it cleaned so Kris said he could do it on this visit. Once again he did an excellent job, explaining to me what he was doing, and what I could do to make the job easier the next time. Two weeks later, my sink next to the toilet plugged up. I called Thornton Plumbing again and they said they would send Kris between 2-4 PM that day. However, Kris was detained on other jobs and never arrived. Brent called me about 4:30 PM and explained Kris was detained. Brent said he was at the office and he was willing to come out and fix the problem, but it would take him about an hour to arrive. I had taken the day off work so I could be at home when they arrived, so I asked Brent to come out. Brent did not arrive until 7 PM, two hours later. We were both tired by that time. The work they did was always very professional. I did feel that the second problem should probably have been solved on the first visit. Brent said he would not charge me for the extra service trip. I will call them again, but I will ask them to be sure and let me know if there is any chance they won't be able to make the scheduled time. I have to take off work to be home for repair people, and it was upsetting when Brent did not arrive until 7 PM."

Basement Waterproofing FAQs, answered by experts

Whether your homeowners insurance covers slab leak repairs depends on your specific policy and the cause of the leak. Many policies cover slab leaks resulting from a covered peril, such as a natural disaster, a falling tree, or pipes freezing and bursting within the slab. However, damage caused by invading tree roots, corrosion, or leaks from appliances may not be covered by a standard policy. It's a good idea to also check your home warranty plan for potential coverage if an appliance is the source. Contact your insurance provider for a full explanation of what your policy covers.

The best ventilation for a crawl space is a fully encapsulated crawl space with its own separate ventilation system. If you go this route, ensure you have the proper crawl space code requirements done and dusted before encapsulating your crawl space with a moisture barrier and installing appliances that may not be up to the proper specs.

Having a trusted crawl space contractor is the key to great encapsulation. If you're not sure how to hire a crawl space pro, begin by asking your neighbors for referrals. Homes in your neighborhood will often have a similar foundation to your house, and personal recommendations are one of the best ways to find a contractor. Additionally, double-check that the contractor has experience with encapsulation as well as proof of their license and insurance.

If not properly maintained, an underground downspout may damage your home's foundation. A clogged downspout can back up, causing water to pool around the base of your home and seep into the foundation. Regular inspections and maintenance keep your downspout in good working order, preventing damage and protecting your home.

Roughing in and connecting utilities are the hardest parts of finishing a basement, and they’re the parts we typically don’t recommend doing as a DIY project. Unfortunately, your finishing timeline can be extended by weeks while you wait for contractors and inspectors to install electrical wiring, plumbing lines, and heating/cooling equipment and carry out inspections.
