"We called with a backed up drain in the basement. That same morning, Joe showed up exactly when he said he would and quickly cleared the drain of rock and sediment. He was really helpful in explaining how this particular type of drain works and how rock and sediment got into the drain. He was friendly and professional; additionally, the price was very reasonable for the service. He pulled a lot of gunk, rock, and sediment from the drain! We will definitely call Valdel Plumbing the next time we need any plumbing work done."

"I had a shower drain line that was leveled and too small. You could see the plumbing underneath the bathroom from the drop ceiling in the laundry room. I called multiple plumbers and they all told me that I needed a new bathroom. Unfortunately, I wasn’t able to do that because all the estimates came in at 15K. Not practical at all! I called plumber after plumbing and pretty much all of them couldn’t help and or blew me off. I finally found Valdel Plumbing and Steve came out to my house. Right away, this specialist told me that he was able to reroute my tub drain line above my drop ceiling below to the sewage line. He did an unbelievable job and I would HIGHLY recommend asking for him. He saved me literally thousands and thousands and thousands of dollars. Thank you, Steve. FIVE stars."

"Unique is true to their name. What a great company! I needed a new HVAC system. Curt from sales came to my house and did a very thorough evaluation of my existing HVAC system. He painstakingly took pictures of my system, took several measurements, and both asked and answered a myriad of questions in order to ensure I would have the right system installed. In addition, Curt told me to call or text him with any questions. When I did so, he answered me immediately. He provided me with different options to fit my budget, and made sure I was confident in my ultimate purchasing decision. When it was time for the installation to be performed, installers Bruce and Jeff were tops! They did their own evaluation, and made some observations and suggestions that helped my new system function optimally. I'm sitting in my warm house as I write this, with a great new HVAC system, and a company I can continue to rely on in the future to keep my new system running at it's best. I look forward to the warmer weather for various reasons of course, but I will enjoy having a house that stays cool for a change! Do your homework and get your estimates from other companies. You'll find as did I, that Unique goes above and beyond relative to other companies. They have an old school customer first mentality that is most welcome in an age where it's not always easy to find good companies. Kudos!"

FAQs for drain clog or blockage clearing projects in King Of Prussia, PA

Snaking a simple clog near a tub, toilet, or sink often takes about five minutes. Deeper blockages along the main line can stretch the job to a few hours because the pro must feed extra cable and may need a camera to confirm the pipe is clear. Either way, specialized tools help pros work quickly and keep your drains running for the long haul.

Aggressive snaking can scratch pipes, push debris deeper, or even crack older lines. That risk is low with an experienced plumber who matches the cable size to the pipe and eases the snake through bends instead of forcing it. If you’re unsure of your technique—or your pipes are already fragile—calling a licensed pro is the safest, and often cheapest, move.

Start with simple barriers: mesh screens on every tub, shower, and sink keep hair, food bits, and jewelry out of the pipes. Skip harsh chemicals; a monthly flush with hot (not boiling) water clears light buildup without damaging plastic lines. Finally, practice smart disposal—no grease, wipes, or kitty litter down the drain—and schedule routine cleanings if you have older plumbing.

Roto‑Rooter typically charges a flat $160 to $450 for standard snaking, which may include a quick sewer inspection and basic clean‑out. Exact pricing depends on the clog’s location and complexity. Repairs or part replacements fall outside that flat fee, so ask for a line‑item estimate if your tech spots broken pipe sections or recommends additional work.

Most liquid cleaners rely on caustic chemicals that eat through hair and grime—but they also erode metal and even some plastics over time. Repeated use strips protective pipe coatings and can leave you with leaks or premature failures. If hot water or a plunger doesn’t help, call a plumber for mechanical removal instead of pouring more chemicals down the line.
