"Mark told me he would be at my house at 10:30 and he was. He spent close to three hours to unclog the drain that backed up into my dishwasher. He took all the old plumbing from under the sink and replaced it with all new pipes and fittings. He tested everything to make sure there was no leaks before he left! Excellent job! I will recommend him to my family and friends."

"Melinda,a very pleasant customer service person,called me promptly this morning 15 or 20 minutes after my post of our need. A tech could come today to unclog our drain. Very pleasant tech came to do the job, Steve. I haven't seen much about pricing for this service.While I was looking for a plumber this morning I did see some ads By other companies to unclog a drain for $250. This company charged $225 for the first hour and was prepared to use a camera if necessary within that price. Very good and briefexperience overall."

"We hired Budget Dry to review our basement problems and hired them to do the waterproofing project, install new basement windows, install the Santa Fe dehumidifier, and recently they installed our back-up battery system. We highly recommend them -always courteous, get the jobs done quickly and neatly, and always respond when we need their advice/want to purchase new filters. A great company!"

"The job took 1.5 days because I had moved everything to the center of the basement. They had 5+ feet of clearance around the perimeter, with plastic covering hung from floor joists. The dust still managed to cover everything behind the plastic walls. My advice: do a thorough job of sealing the space or be prepared to have a big dust cleanup. Only disappointment was that the drain at the foot of the steps to the bilco doors was positioned directly below the internal door. You cannot install a sill on top of this so when finishing we will now have a dangerous transition. This was never explained. Otherwise, a great crew."

French Drains FAQs, answered by experts

Common causes include hair buildup, soap residue, food particles, and foreign objects. Older pipes can also contribute by facilitating buildup more easily.

If your dishwasher keeps filling with water at the bottom but doesn’t fill into the sink, the issue is likely due to a blockage within the dishwasher or drain. Regularly clean your dishwasher filter basket to ensure it’s not clogged with food, and run a vinegar rinse periodically if you have hard water to remove limescale buildup.

The best way to unclog a bathtub drain is to pour a pot of boiled water down the drain, being careful not to splash yourself. However, take precautions, as boiling water can damage PVC pipes and joints. Follow up with ½ cup of baking soda and ½ cup of vinegar. Cover the drain with a small sink plunger and let it sit for 15 minutes. Pour boiling water down the drain again and replace the drain stopper.

For homes with a septic tank, harsh chemicals like those found in drain cleaner or bleach aren’t recommended. Some chemical drain cleaners can disrupt the balance of bacteria in the septic tank or damage your pipes. For homes with a septic tank, you can choose drain cleaners specifically formulated for use with septic tanks or go with a drain snake. When in doubt, make sure you know who to call for a clogged drain. 

Chemical drain cleaners can work to clear clogs in pipes, but their use should be approached with caution. These harsh chemicals can damage pipes over time, and they can also harm the environment. Use them sparingly and consider alternative methods such as using a plunger or a drain snake. If you have concerns about a persistent clog, it's best to consult a professional who can safely and effectively address the issue without causing further damage to your plumbing system.
