Window Cleaning FAQ - Stone polishing & restoration

Frequency depends on stone type and traffic levels. For medium-traffic commercial lobbies we typically recommend a professional maintenance visit every 12-24 months and a light cleaning program quarterly; high-traffic retail or transit-adjacent lobbies may need polishing or restorative work more frequently. We provide a site assessment to recommend a tailored schedule that balances appearance, durability and cost.

We service a broad range of stone surfaces including marble, granite, limestone, travertine, terrazzo and slate. Each material responds differently to mechanical finishing and chemical treatments, we test and select methods and products that preserve the stone’s character and long-term performance.

We use dust-control polishing systems and flexible wet/dry methods to minimize airborne particulates and cleanup. Standard restoration produces some noise inherent to mechanical polishing, so we plan workwindows, provide sound-mitigating staging, and coordinate with building operations to limit impact during peak hours.

Yes. We perform single-project restorations, for example after construction, heavy staining, or damage, and we also design recurring maintenance programs that include scheduled cleaning, polishing and resealing. Ongoing plans reduce overall lifecycle costs and help maintain a consistent presentation.

We offer a complimentary on-site assessment and written estimate for most commercial scopes. The free estimate lets us evaluate stone condition, traffic patterns and required access so we can recommend the right treatments and maintenance cadence.

By NYC law, applicable sales tax will be added to your invoice. We include tax determination in every estimate and clearly itemize any taxable components for your accounting team.

No. For most commercial jobs a designated building contact (property manager or facilities lead) is sufficient. We conduct a pre-work walkthrough with point-of-contact, provide a clear work plan, and complete a post-work inspection. If a client prefers to be present for start or finish, we accommodate that scheduling request.

All Top Team technicians arrive in company uniforms and use branded vehicles. Before any work we provide a written scope, confirmed schedule and contact details for our project supervisor. If you require additional vetting or contractor onboarding documents, we supply certificates of insurance, safety credentials and references.
