"I called them when my sump pumps (primary and backup) dies and I had water in my basement. Rob told me over the phone what it would cost to replace them, and said he could have someone there in two hours. I had talked to three other plumbers before I heard from RA Mechanical. NONE of them could give me a window of when their tech could come. No offers of pricing, either. A licensed, experienced, competent plumber arrived in my two-hour window. He cleared away the broken equipment, installed the new equipment, cleaned up, and was on his way. Cost was exactly the estimate. I would RA again in heartbeat. Rob and his people are first-rate."

"I had Ken and his crew come out in Dec. 2019 to install a new shower and replace two sink faucets in our primary bathroom. They did a great job. We did need a little warranty work done recently and they sent out a service technician who did what we asked courteously and professionally. I love a company that stands behind their work and Prime Baths in Coal City does just that. Will use them again as needed for sure."

"Anthony and the crew at â Pitch Perfectâ has done an amazing job on multiple projects in our home. Everything from a new well tank and a complete water filtration system with a polisher and softener to a new A/C condenser and A-coil. He has done multiple smaller jobs also including toilet install and rodding of all the lines in our home along with overall seasonal maintenance on our furnace and AC units.. Whenever I call Anthony he is here in a timely manner, always considerate, professional, and clean! He has been our â go toâ plumber/HVAC guy for years and I donâ t see us using anyone else ever again! HIGHLY RECOMMEND! FIVE STARS!"

"Excel Windows and Bath are extremely professional and customer oriented. From the moment the sales person came to the door to the installation was finished, they were there to assure everything was done correctly. The product was a good value for the product, and when I need windows again I will definitely call them. I would rehire them for tub to shower but only had one that needed converted."

"I looked a 6 contractors and their views but none of them except, Batcrest of Chicago showed promise. Both Don, the owner, and his wife Carole came to my home to make a presentation on the removal of my old bathtub and shower. Both my wife and I were impressed with their presentation and price quote. They both told my wife and I that their employee Ken was meticulous in his work and always clean up thoroughly, that was another good point of reference! I am grateful that we hired Bathcrest, what an outstanding job done and completed with Ken. He is everything that we needed, a person that is focused and highly skilled. Both Don and Ken worked with me as I had some changes mid-stream that I wanted focused on, safety bars, as I am a senior and down the road I may really need help. Don and Ken gave my wife and I a beautiful and safe master bathroom, more than we could imagine it's beauty, usefulness and safety. This is the kind of company that you want to hire, you won't regret my recommendation."

"Nick and Gus installed a hot water tank. They were amazing - so thorough and professional. They explained the process involved and went above and beyond checking to make sure all faucets and tub were working properly after shutting off the water. Also, they took the time to explain to me how to understand the way my battery operated sump pump works with technology. Fantastic workers!"

Plumbing FAQs, answered by experts

Yes, you can put a bathroom in a bump-out. Some homeowners build a bump-out to enhance their bathrooms with new sinks, vanities, tubs, showers, or linen closets. Depending on the layout of your bathroom and what you’re adding to it, you may need to install new plumbing or reroute your existing plumbing lines.

Plumbers will typically take one to two hours to install a new drain pipe, but that timeline can vary based on the area’s accessibility, the drain length, and the type of drain line. Replacing an easily accessible p-trap under a sink could take as little as a half an hour, while replacing a larger section of drain line behind the wall could take as long as three to four hours. When hiring a plumber for your specific installation, ask them to provide an estimated timeline to get a more accurate assessment.

No, it’s not safe to use a blowtorch or any open flame to thaw pipes. The intense heat can cause the pipe to burst and/or start a fire, leading to very costly damage. Instead, use safer external heating alternatives, such as heat tape, a space heater, or an infrared lamp. 

No, homeowners should never attempt to fix a gas leak themselves. Gas leaks pose serious health and fire hazards. Exposure to leaking gas can make you sick, and accumulated gas can ignite and explode. So always take leaks seriously and seek the help of a pro right away. While you may be able to detect a gas leak, always call a licensed professional to handle repairs and replacements.

A sewage smell in your crawl space is usually from a damaged or clogged pipe leaking sewer gasses or actual sewage underneath your home, but there are some other common causes. Moisture, from poor or damaged encapsulation or a malfunctioning sump pump, can harbor mold and bacteria, causing a musty smell. Pests can also get stuck in your crawl space and die, which causes a sewage-like odor.
