Why Homeowners in Capitol Hill, WA Trust Us

Monty showed up on time and kindly walked me through the service needed to fix the low water pressure in the shower. He quickly understood how to fix the problem and was incredibly efficient and thoughtful throughout the process. He did a great job, and I am very satisfied with the results. Thank you for the excellent service!

My wife and I live in a 120 year old house and when some old metal pipes backed up and started leaking we called the right people. Cameron came out and did a thorough inspection and clearly explained what was going on. Next morning, came out removed the old pipes and installed new ones. Problem solved and we couldn’t be more satisfied with his help.

OMG! Fantastic and quick service! Found a wet spot in the basement ceiling. Cameron was out the next day shortly after we called, found the problem, gave us our options, and began work immediately. While we were at it, we had our kitchen faucet replaced! Cameron was very nice, very thorough, and stopped to give our dog a pet each time he went in and out to his truck. Highly recommend.

Signs Your Garbage Disposal Needs to Be Replaced

Garbage disposals show a few clear signs before they fail. Here are the usual signs that point to a replacement rather than another repair.

Frequent jamming
Persistent bad odors
Slow draining
Leaking under the sink
Unusual grinding noises
Needs frequent resetting
Reduced grinding power
Unit older than 10 years

Seattle’s water tends to run harder than in some regions, and mineral buildup over time can cause a disposal system to work less efficiently than it used to. If your unit is already older and showing several of these signs at once, replacement is usually the more practical option compared to repeated repairs that only buy you a few more months of use.

Finding the Right Garbage Disposal for Your Kitchen

Choosing a new garbage disposal comes down to a few key factors, starting with motor size. Households that cook frequently and put the disposal through daily use generally benefit from a more powerful motor. In contrast, households with lighter use can often get by with a smaller, more affordable unit. Our technicians ask about your kitchen habits before recommending an option, rather than pushing the most expensive model available regardless of whether you actually need it.

Noise level is another consideration that many homeowners do not think about until after installation. Some models run noticeably quieter than others, which can matter a lot in open-concept kitchens or homes where the sink is close to living spaces. We explain the tradeoffs between noise, power, and price so you can weigh what matters most for your household and how you actually use your kitchen.

Durability and warranty coverage also play a role in choosing the right unit. Some disposals are built with more durable components meant to withstand years of regular use, while others are designed for lighter, more occasional needs. We walk you through these differences honestly, without steering you toward an upgrade you do not actually need for your kitchen, and we are happy to answer follow-up questions until you feel confident in your choice.

Our Installation & Replacement Process

We start every job with a quick assessment of your existing setup, whether you are replacing an old unit or installing a disposal for the first time. This helps us confirm the new unit will fit properly and connect correctly to your existing plumbing and electrical connections. Older homes sometimes require minor adjustments to accommodate a new disposal, and we explain any of that upfront before work begins, so there are no surprises once the job is underway.

Once we have confirmed the right fit, we give you a clear price for the installation before starting any work. There is no guessing what the job will cost and no pressure to add extras you have not asked for. Our technicians handle the removal of the old unit, if applicable, and the full installation of the new one, ensuring all connections are secure and leak-free.

After installation, we test the unit thoroughly to confirm it is running properly and draining as it should. We also walk you through basic care tips, like what should and should not go down the disposal, so you get the most life out of your new unit going forward. Our technicians are happy to answer any maintenance questions before they leave, so you feel fully comfortable with your new system.

What You Gain With a New Garbage Disposal

A new garbage disposal does more than just grind up food scraps more effectively. Modern units tend to run more quietly than older models, which makes a noticeable difference in daily kitchen use, especially for open floor plans where sound carries easily into living spaces. Many newer disposals are also more efficient, with less horsepower needed to handle the same workload, which can mean a small reduction in your energy use over time.

Odor control tends to improve significantly with a new unit as well, since buildup and grime in an older disposal are common sources of persistent kitchen smells. A properly functioning disposal also puts less strain on your plumbing overall, reducing the likelihood of clogs from food debris that an aging unit may not fully break down.

There is a reliability benefit, too. A new disposal is far less likely to jam or require constant resetting, which means fewer interruptions during everyday cooking and cleanup. For many households, that consistency alone makes the upgrade worthwhile, especially if the old unit had become a daily source of frustration.
