"Look, you're not calling a company like FWDR because something happy has happened... Our refrigerator flooded our kitchen - exposing a small, long-term leak that had slowly destroyed our cabinets, drywall, and floors without for years our knowledge. We now had ourselves a water damage AND a mold problem and had no idea where to start. We were lost and stressed and didn't know who to call. I did a quick search and found FWDR because of all of their amazing Yelp reviews. One call to FWDR turned a stressful situation into a manageable project with knowledgeable support all along the way. Javier was always able to quickly and patiently answer my questions (and I had a lot of questions), he referred us to several companies to deal with prerequisite issues (asbestos and lead testing and removal), and it felt like he was there to walk us through the whole process. I can't tell you how much I appreciate the patience and consideration Javier, Santos, and Margarita showed every step of the way. They worked with the other vendors and my insurance directly to make sure that no time was wasted between services from different companies, the work was quick and thorough (proof received through testing), and every consideration was given to my family with two toddlers and small home during a pandemic - they did their very best to work around us and our day to day needs. I can't thank them or recommend them enough. Attentive, detailed, courteous, patient, thorough, and going well above and beyond in customer service - you really can't ask for more from a company you never really want to have to call in the first place!"

"Three men were sent to get everything cleaned up in a day. They also arranged for the plumber to go and make the pipe repair the next morning so that my tenants were not inconvenienced for more than one day. They did a very good job cleaning and sanitizing the area."

"Mike was professional and fixed both showers, noting that the shower pipe valve for our new shower/tub had been installed incorrectly. He was very pleasant and professional. In fact, we had a toilet overflow and ceiling water leak hours after he left -- he was responsive over the phone and we were able to diagnose the problem. He even texted me afterwards to see if there was still a problem (there wasn't). Would use Mike again in a heartbeat. He is our plumber of choice moving forward."

"Awesome job! Best price out of 3 other competitors. Lead time was reasonable. Installation turned around in 3 and 1/2 days. There were several guys working on the house. All are very friendly people. Couple places where I found minor issues, they fixed them instantly without any BS conversations. True professionals! Rob was my sales who got a great deal for us and helped pushing through the permit, thank you Rob! Francisco was the installation boss, thank you Francisco!! I highly recommend SGK, they made me a lot happier :)"

"We needed someone to replace our windows, and a friend recommended EDI, we called them and they responded very quickly and gave us a good price to replace all our windows. Having them working on that, we have decided to go ahead and replace floors, added also an interior paint and install new lights in our kitchen, living room, bedrooms and hallway. The place looks pretty much brand new now, all we have left to do is to renovate the bathrooms. We are very pleased with everything they have done for us."

Install Garbage Disposal FAQs, answered by experts

While the drain connection for a garbage disposal is nearly universal and fits standard sink drain holes of 3 1/2 to 4 inches, the size of the disposal unit itself is not. You must have enough space in the cabinet underneath your sink to accommodate the disposal's housing. A larger model may not fit in a compact cabinet or if the existing plumbing is arranged in an unusual way. Before buying a new garbage disposal, measure the available space under your sink. If you are replacing an old unit, it's often easiest to choose a new model of a similar size.

Whether it's worth repairing your garbage disposal depends on its age and the specific problem. Generally, if the unit is eight years old or younger, repair is a good option. For minor issues like a bad seal or a simple jam, a repair can be inexpensive, sometimes under $10. However, if the motor is broken (a repair that can cost $150 or more) or the unit is getting old, it's often more cost-effective to replace the entire disposal.

On average, a garbage disposal can last anywhere from 7 to 12 years, with many models functioning well for about 10 years. With heavy usage, a motor may last a minimum of five years, while grinding plates will wear down over time. It's generally a good idea to consider a replacement if your unit is approaching the 10-year mark. Other signs that it's time for a new disposal include frequent leaks, persistent clogs, lingering odors, lack of power, or unusual noises. If your unit is not that old, it's worth investigating if a less expensive part, like a rubber seal or a loose hose, is causing the issue.

No, you do not need a garbage disposal to have a dishwasher. A dishwasher will work without one, and while it's rare to see a home with a dishwasher that doesn't have a disposal, it is possible. The two appliances pair well and are often installed together because a disposal simplifies meal cleanup.

However, your dishwasher should not be used as a replacement for a garbage disposal. Subjecting it to continuous food leftovers can lead to major clogs. If you choose not to install a garbage disposal, you should thoroughly rinse your plates or scrape excess food into the trash or a compost pile before loading them into the dishwasher to prevent plumbing issues.

When a dishwasher discharges its wastewater, it uses a pump to quickly move a lot of water. If anything in the drain line or the garbage disposal impedes the high volume of water, it will back up into the sink through the drain or the garbage disposal. Following regular dishwasher maintenance tips like clearing clogs, keeping them cleared, and occasionally running the disposal will eliminate the problem.
