"Our water heater started leaking on Sunday. Isaac responded to our query within minutes. He rearranged his schedule to be here early Monday morning. He arrived on schedule and our water heater was installed and functioning by noon. He is not only professional, fair and knowledgeable but a great guy."

"Joe and his son David were very professional, yet personable. They showed up every day as planned and did a great job remodeling my shower. They cleaned up after themselves each day and kept me abreast of their progress. Joe offered suggestions to the project and his experience showed. I would not only hire them for future tiling projects, but refer them to my friends and family."

"Home improvement construction is stressful. There's a lot of bad actors out there. These guys are the complete opposite- total pros who take great care in consultation to installation. They did a great job on my project, looks great and so far the work is great."

"The gutter replacement and the exterior paint went well. The work was done within the timeframe as discussed. I was very pleased with how it came out and the team (led by Nathan Rabinovitch) was responsive with my calls and texts whenever I had questions. There was delay with creating a door access to the backyard but it was due to permit issues. Once the permit was approved, everything went smoothly. I will hire them again for future projects."

"After having remodeled our kitchen several years ago, we had KN remodel our master bathroom. Great guidance, from the construction stuff we don't understand to the aesthetic discussions we much appreciate. Done on time, and with great clarity around the billing. And the crew was great -- neat, thoughtful, on time, helpful. A big thumbs up."

FAQs for shower installation and replacement projects in Ontario, CA

You should regrout tile every 10 to 15 years, provided it is well-maintained with regular cleaning and sealing. Over time, grout can deteriorate due to exposure to moisture, foot traffic, and the use of cleaning agents. If you start to see cracks, discoloration, crumbling grout, or loose tiles, it’s a sign that regrouting is needed sooner.

The most effective way to clean grout involves a combination of powerful cleaning agents and the right tools. Using a dedicated grout brush intensifies the cleaning process, ensuring a deep clean. Create a powerful homemade solution by mixing baking soda, hydrogen peroxide, and dish soap to break down deeply embedded dirt. After cleaning, reseal the grout to lock in protection and maintain its appearance.

You can't regrout tile without removing the existing grout and expect good, long-lasting results. You must replace the old grout when it begins to crumble and fail. New grout cannot properly adhere to existing grout, meaning moisture will still reach the damaged layer and cause additional water damage, which will be more costly to deal with in the long run.

Visible indicators, such as cracks, stains, chipping, and mold growth, signal that your grout is compromised and no longer maintains its bonding strength. If you notice these issues, cleaning alone won't restore the grout's integrity. In such cases, consider complete or partial regrouting to preserve your surfaces and prevent further damage.
