Do you work on countertops?

I can clean and seal bathroom vanity tops and kitchen countertops. For significant countertop restoration work, I recommend specialists who focus exclusively on that work.

How long does sealer last?

Quality penetrating sealers typically last 1-2 years in shower environments with proper maintenance. The exact timeline depends on stone porosity, water exposure, cleaning habits, and water quality. I’ll help you understand what to expect for your specific situation.

What's the difference between cleaning stone and sealing it?

Cleaning removes dirt, soap, minerals, and contaminants from the stone surface. Sealing provides ongoing protection by filling the stone's pores with a protective treatment that repels water and prevents staining. Both are important—cleaning prepares the surface, sealing protects it long-term.

Can I use vinegar or lemon cleaners on my stone?

Absolutely not. This is critical: acidic cleaners (vinegar, lemon, many "natural" cleaners) will etch and dull marble, travertine, and limestone. Even brief exposure can cause permanent damage. Always use pH-neutral, stone-safe cleaners. I’ll provide specific product recommendations during service.

How do I maintain my stone between professional services?

Daily: Squeegee glass and wipe down stone after each use to prevent buildup. Weekly: Clean with pH-neutral, stone-safe cleaner (I’ll recommend specific products). Avoid: Anything acidic, abrasive scrubbers, and high-pressure washing. I provide detailed maintenance instructions with every service.

Can you restore etched marble or damaged stone?

I specialize in cleaning and sealing, not restoration. If your stone has etching, deep stains, or damage beyond what cleaning can address, I’ll be honest about it and can recommend qualified stone restoration specialists. Some surface etching can be improved with professional cleaning and sealing, but significant damage requires restoration work.

How often should natural stone in showers be sealed?

Generally every 1-2 years, but it depends on stone type, usage, and water quality. Some stones (like marble) need more frequent sealing than others (like granite). During our service, I’ll assess your specific situation and recommend an appropriate schedule.

Will cleaning remove hard water stains from my shower glass?

In most cases, yes—I can remove hard water deposits and mineral buildup from glass using safe, effective methods. However, if glass has been permanently etched by minerals (this happens when deposits sit for extended periods), those marks may be permanent. I’ll assess your glass and be honest about what's achievable.

Are your cleaning products safe for all natural stone?

I use pH-balanced, stone-safe products specifically designed for acid-sensitive materials. Unlike general cleaning services using standard products, I select appropriate chemistry for your specific stone type. That's the value of specialized training.

Can you clean and seal grout in my stone shower?

Absolutely. In fact, grout sealing is critical in stone showers. Unsealed grout absorbs water, soap, and contaminants, leading to discoloration, mold, and eventual deterioration. I clean grout thoroughly and apply appropriate sealers to protect it.
