"We had a blockage somewhere in our plumbing line and couldn't use our upstairs toilet for over a year. Our contractor Ben Sviri from Creative Home Remodeling Group came out to our condo with his plumber to assess it. Not only did they find the blockage (PVC pipe), they also removed it and patched it up the same day! We definitely recommend them with any home project you may have."

"First Thought Plumbing's Kenny is very professional, punctual, knowledgeable, pleasant and offers affordable and reasonable rates for his great service. I searched for a plumber yesterday and he was the first to call and respond to my need. He came on time, he knows what to do, very responsive to inquires via phone or text. Amazing, professional worker who won't price gouge or try to upsell you. Recommendable! Thanks Kenny!"

"Nathan impressed from the time I first met him. He was far more professional than other contractors in terms of describing how his company works and what I should expect if I worked with him. He also has a nice showroom where you can look a variety of cabinets in different styles and colors as well as countertops. We ended up getting a countertop that he suggested. We would never had picked it on our own but it ended up looking amazing in our kitchen. We had him do a complete remodel of our kitchen and one of our bathrooms. The guys on his crew were always prompt and showed up as scheduled. His foreman was both a good communicator and listener. Whenever we ran into an unexpected issue, they communicated clearly what additional costs would be involved (if any) and how much additional time it might take. The cabinets he installed were custom made but did not cost more than the pre-fab ones you can buy at the large home improvement stores. They are of high quality and well constructed. I actually saw his cabinet guy using a small caliper to make sure the door distances from the cabinets were all even! Lastly...here's something you'll never hear about a contractor...he finished AHEAD of time! Nathan's company are straight shooters and very skilled craftsmen. I would work with them again."

The average cost to snake your main sewer line is around $250 for a simple snake. Most sewer line specialists charge between $45 and $200 per hour for main sewer line snaking, so the time involved plays a major role. The price you’ll pay will depend on the severity of the clog, the item causing the backup, how long it takes to remove the item, and more. A more severe issue that requires unclogging a main sewer line will cost $3,100 on average.
