A Bathroom in Lexington Shines Again Thanks to Our Grout Cleaning Experts

May 23, 2025

Bathrooms are meant to be a place of comfort and relaxation. That is, until mold and grime take over. That was the dilemma a homeowner in Lexington faced when she realized her bathroom no longer felt clean, no matter how hard she scrubbed. The floor, for instance, had grown discolored with years of wear, but the real problem was the bathtub area, where mold had taken over the grout lines. Frustrated by the lack of results from store-bought cleaners, she searched on the internet for a solution and came across our grout cleaning service in Lexington.


She explored our site and was immediately drawn to our detailed service pages, the glowing reviews, and the gallery of before-and-after photos showing real transformations. Hoping to avoid the cost and hassle of remodeling, she decided to schedule a free in-home evaluation. Also, she was especially interested in a long-term solution that would keep the mold from returning.

Our specialists arrived at her home on time, wearing Sir Grout uniforms and driving our company's vehicle. As soon as we stepped into the bathroom, it was clear that the grout around the bathtub was the area most affected. Mold had settled into the lines, making the space appear worn out. The floor grout, while not as severe, was soiled and uneven in color from years of foot traffic and ineffective cleaning methods.


We explained how certain over-the-counter solutions, especially acidic or soap-based cleaners, can do more harm than good. They often leave behind residues that attract more dirt or even weaken grout over time. Fortunately, the damage in this bathroom wasn't permanent. We offered her a full plan for restoring both the floor and bathtub area, including a detailed explanation of the process. With a clear understanding of what to expect and reassured by our professionalism, the client booked the restoration for later that week.

When we returned for the appointment, we began by applying a powerful permeating cleaner across all tiled surfaces. This specially formulated solution helps break down stubborn grime, soap scum, and mold buildup embedded deep within the grout.

For the bathroom floor, we used a high-speed scrubber designed to reach deep into grout lines. This equipment allowed us to effectively remove years of accumulated dirt and grime, restoring the grout's natural tone. Even at this stage, the improvement was clearly visible.

In the shower and bathtub surround, however, where mold was more prominent, we brought in our vapor steam cleaner. This tool uses high-temperature steam to sanitize and dislodge the mold and mildew from the grout and tile without damaging the surfaces.

Next, we thoroughly dried the area to prepare the grout lines for sealing. We applied our professional-grade sealant, ColorSeal, to both the floor and the walls surrounding the bathtub. This not only refreshed the appearance of the grout, giving it a crisp, clean look, but also created a protective barrier that helps prevent future staining, mold, and moisture penetration.

The difference was notable. The space now looked fresh, polished, and inviting, so of course, the client was amazed. She couldn't believe how clean the grout looked and told us the bathroom finally felt like hers again. She thanked our team repeatedly and promised to recommend our services to friends and family dealing with similar issues.

To help her keep the surfaces in top condition, we shared a few maintenance tips. First and foremost, we advised her to use a pH-neutral cleaner, such as Sir Grout's Natural Hard Surface Cleaner, which safely removes dirt without affecting the sealant or encouraging the growth of mold. We also suggested avoiding bleach and vinegar, which can deteriorate grout and cause further damage. Additionally, we recommended regular ventilation of the bathroom to reduce humidity and the risk of mold, especially in shower or tub areas. Drying surfaces with a towel after use can also make a big difference over time.
