"My wife and I bought a house a couple years ago, and became owners of a radiant heating systems installed more than 20 years ago. Tony and Damian did a great job of understanding how my radiant heating system works, what repairs were needed/what was failing, and where upgrades were needed. They replaced the pump, both expansion tanks, and the neutralizer. Additionally, they noticed the hot water tank was installed incorrectly, and the hot and cold water connections were flipped. It's amazing the system worked, and it's nice to have a system that's correctly installed (even if it's 20 years later!). Additionally, they secured the expansion tanks to the wall (now required by code), replaced the deteriorating copper pipes connected to the neutralizer with plastic (I'm sure this is code now as well), and re-routed the overflow pipes to the outside (rather than the floor!). You can't go wrong with these guys, well done, they're true craftsmen to the trade."

"Very knowledgeable installer. The owner of the company also visited my home to deliver materials and check on the job. Starving Plumbers installed the water heater the day after I called them, so we were without hot water for just a single day. Knowledgeable and very professional. They were about $500 less for a top of the line American Standard Shorty Tank than the price another local plumbing company quoted."

"We were in need to Remodel our Bathroom due to leak from the pipe in between two Bathrooms and change out the plumbing of our house from galvanized steel to copper, upgrade drain to ABS pipes. Geico Builders crew had an immediate availability to solve our issues. Mila was assigned to our project as a project manger. The communication of the project manager was outstanding as well as guidance on what has to be purchased for completing our beautiful Bathroom. Once the water leak was discovered and the subfloor damage was assessed. A repair plan was quickly in place for the leak. Plus a plan to restructure and build a stronger subfloor. Overall, Mila and Supervisor Ruiz and their team were very excellent at staying on schedule and completing the project with quality workmanship. Overall we are very happy with our beautiful new bathroom. Our renovation project was completed on time and the new look absolutely met our expectations. Our main expectations/requirements were a regular shower pan, the shower walls and the flooring, all done with quality porcelain tile. Adding a shampoo niche and 2 safety grab bars in the shower area. Plus the bench which I am so happy with. All of these items were installed with attention to detail and with quality workmanship. Thank you Geico Builders for your professionalism and hard work we are truly Happy with everything you had done to our house and looking forward to work with you for our new project which is going to be Kitchen Remodeling by next year."

Drain Pipe Installation FAQs, answered by experts

The cost to unclog a drain varies based on the location and severity of the clog. For simple clogs within your home, such as in a sink, toilet, or shower, hiring a plumber typically costs between $110 and $350, with an average of around $200. Snaking a toilet or sink usually costs between $110 and $275, while a bathtub or shower clog costs about $225.

For a more serious clog in the main sewer line, the cost is higher. Clearing a main line clog generally costs between $200 and $600, with an average of about $380. However, prices can range from as low as $100 for snaking a minor clog to over $1,600, particularly if advanced methods like video inspection and hydrojetting are needed for a large or hard-to-reach blockage. Some severe main line clogs can cost upwards of $1,000 to clear depending on factors like the cause of the clog, its distance from an accessible cleanout, and whether the pipe is located beneath an occupied space (e.g., in an apartment building). You may be able to save money on minor clogs by using a drain snake or bladder yourself.

Snaking a drain can take as little as a few minutes for small, simple clogs, up to two hours or more for tough clogs located further down the drain line. For tougher clogs, a professional drain cleaner can likely get the job done much more quickly because they have the necessary tools and expertise. However, your drain cleaning pro might not be able to give you a firm time estimate until inspecting the clog and its surrounding plumbing.

You can often unclog a garbage disposal in less than 10 minutes, though sometimes you might need longer if you’re unsure what’s causing the clog. For minor clogs, consider plunging the drain, flushing the drain with baking soda and vinegar, or using an Allen wrench to free the clog. If the clog is more severe, contact a local plumber.

Some homeowners use additives every month to help septic system performance, but according to the U.S. Environmental Protection Agency, the effectiveness of septic system and leach field additives is unknown. Further, additives made with organic solvents or alkali chemicals can actually be harmful to the necessary bacteria in a septic system.

Bleach is generally not recommended for your shower drains. Although diluted bleach can technically help clean your drain, it will not unclog your pipes. In fact, bleach can harm your plumbing system because it’s so powerful. The bleach can change the color of your sink and even corrode metal pipes and fittings.

Often, people reach for bleach because it's already in their house. But it's worth getting a plunger or a drain snake for the job instead. It'll be a lot less money to buy a new plunger than to pay a plumber to repair or replace damaged pipes.
