"This company has been our "go to" business for all of our plumbing issues for years, and just yesterday (July 16) they replaced 10 feet of our sewer line. The crew was extremely gracious, worked well as a team, and took extra care to not damage our backyard. And when the job was done, they took more time to restore our landscaping so that you can't even tell a backhoe was in our backyard! My wife and I highly recommend this company!"

We specialize in all phases of remodeling for your home, business, bathrooms, kitchens, finishing basements, and more! We guarantee your satisfaction, and we won’t leave until the job is done right. We pride ourselves on the quality work we provide, while delivering great customer service! Check out all the services we offer below and call -or- click to schedule a free estimate today!

"In hindsight, I believe we were charged anywhere from five to $8000 more than what we should’ve paid. We had a walk-in bathtub installed and while I like the bathtub, the overall cost was excessive. We prepped the bathroom and removed the old bathtub so they did not have to contend with any remodeling or removal of old construction. The plumbing itself did not have to be moved so the only thing they had to do was deliver and install the tub. I would recommend for anybody using this company to not succumb like I did to the pressure buy. If they’re going to install it, they should be able to give you a quote that they standby as you compare prices with other installation companies. After the installation was completed, we did all the backsplash tiling ourselves as well as decorative tiling around the base of the tub."

We work hard to earn your business and want to be your next reference. We offer a progressive billing system. This helps you avoid large deposit and allows you pay as worked is completed. Our attention to detail and can-do attitude allows us to make your vision a reality. We are licensed and insured for over 35 years. Call now for your free consultation and estimate.

"I hired Paramount back in 2020 for work on the first floor and appreciated their work so much that I brought them back for the basement (fix/ update after mold repair) and second floor (bathroom and stairs update, new carpet). Like the first time, I really appreciated Ryan's suggestions on style and options, and the various contractors were professional and very kind about working around me and the cats. Ryan was ultimately more critical than me about details and appreciate that desire to do things right and as clean as possible. Would use again!... although that would require a new house at this point. 😁"

Drain Cleaning questions, answered by experts

If you've discovered a rather frightening buildup of brown and black gunk below your shower cover, you're not alone. The smelly sludge is often a collection of mildew and biofilm. Biofilm comes from the breakdown of soap scum, hair, skin cells, and bacteria that collects during shower time. It's quite common in a humid space and relatively easy to clean with a gentle DIY cleaning solution such as baking soda and vinegar.

You should hire a sewer service professional to unclog a main sewer line with tree roots. Tree roots can grow into the main sewer line, and this problem requires a specialized hydro jet, or rooter, that is powerful enough to clear the roots. The tree can also damage the main sewer line, and a professional will need to make repairs or replace the damaged sections. Sewer line replacement costs about $60 to $250 per linear foot.

Yes, continuing to flush a clogged toilet is not likely to break up the clog. Instead, it will continue to put pressure on the clog while filling the bowl with more water, which can potentially cause the toilet to overflow—leading to an even bigger mess. Rather than repeatedly flushing, use a toilet plunger or plumber’s snake to dislodge the clog.

The cost to unclog a sewer line is between $200 and $600, with the average homeowner spending around $380, depending on the severity of the clog. It can cost as little as $100 to snake a small clog, but you could spend up to $1,600 if you need to video inspect the line and hydrojet a large clog.

Start by pouring hot—but not boiling—water down the drain. The heat of the water may be enough to break down the clog. You can also try ½ cup of dish soap or 1 cup each of white vinegar and baking soda. If you choose a chemical unclogging product, ensure it’s appropriate for toilets to avoid damage.
