Kegonsa Plumbing was founded in March 2018 by Luke Elsing. After 13 years of plumbing experience, he was exposed to several different owners and management styles. Luke decided to be a different kind of business and prioritize doing what’s best for his customers over his own profit margins. By sourcing only the highest quality products with solid warranties and doing craftsman-quality work on every job, Kegonsa Plumbing earned an A rating on Angie’s List in our very first year of business.

"We used Kegonsa Remodeling for a major kitchen renovation in a nearly 100-year-old house. Before the remodel everything in the kitchen looked cheap and worn down (think 1970s brown, everywhere!), and the overall arrangement of the space was really inefficient. They came in and proposed a design that was the best balance of affordability and ideal features out of half a dozen contractors we interviewed. Once we began working with them, they provided consistent updates and met with us on a regular basis, enough so that even with unavoidable pandemic slowdowns, it still felt like the project was always moving forward. Once the remodel began, they had nearly daily updates for us on what was coming next, and the project actually finished ahead of schedule! Now we have a kitchen that has at least 3x the workspace, a significantly improved flow, and easily twice as much storage as our previous one did. We get compliments all the time, and recommend Kegonsa's work any chance we get!"

"Beware of shipping issues with this company. Ordered an ice maker installation kit on 10/10/25. Shipping was due no later than 10/20 according to company and FedEx tracking. FedEx tracking showed the package at their facility for 8 days without moving beginning on 10/15. Called FedEx 3 times. Each time they said they cannot find package and I have to contact shipper. Shipper has to make a claim, they will not mark it as lost. Called Appliance Parts Pros twice. Each time they say FedEx has to mark package lost before they will do anything. They also state they have to wait 14 days from them before doing anything because of their contract with FedEx. I don't care about their contract, I want what was ordered and paid for.

Solar Panels questions, answered by experts

While solar panels can be a great investment, they aren’t ideal for every roof. For example, some roofs, especially older or structurally weak ones, may struggle to support the added weight, leading to potential damage. Roofs with complex designs, obstructions, or limited sunlight exposure might not provide optimal conditions for solar energy production. Consider these downsides when determining if solar panel installation costs are worth it.

Solar water heating systems are not one-size-fits-all. You'll likely work with a team of experts to get the job done—including solar panel installers, plumbers, and water heater installers. A specialist will help you decide if a passive or active system is best for your local weather, home layout, roof stability, and your budget.

It’s possible to install solar on a tar and gravel roof, but it’s far from the best roofing material for solar. Solar installations require roof penetrations, and although your solar installer will seal the holes, they still increase the risk of roof leaks. Flat roofs are already more likely to leak than sloped roofs, and adding solar will only make leaks more likely.

Most solar panels last 25 to 30 years and have a warranty to match. Over time, you’ll see a diminishing electrical output. This is normal wear, but certain things can hasten solar degradation. These include heavy rainfall, high temperatures, constant humidity that corrodes the frame, and cracks or chips in the glass.

The actual time it takes to construct the solar farm is relatively short, taking between 2 and 4 months on average. That timeline is dependent on site conditions, crew size, and the overall size of the solar farm.

However, the time it takes to get the ball rolling is significantly longer, ranging from 3 to 5 years. With a project of this scale, you’ll need to obtain all of the proper permits and approvals to start breaking ground, and depending on your location, that could be an extended process.
