Frequently Asked Questions

Can R Thomas Frock Inc match historic millwork profiles found in old Baltimore rowhouses?

Yes, we specialize in historic millwork reproduction and have extensive experience matching original profiles from Baltimore’s Federal, Victorian, and Colonial Revival architecture. Our craftsmen can create custom knives to replicate existing mouldings or work from historical drawings and specifications.

What’s the typical lead time and cost difference between stock and custom millwork?

Stock profiles are available immediately, while custom millwork typically requires 2-4 weeks depending on complexity and quantity. Custom work costs 30-60% more than stock profiles due to setup time and specialized tooling, but the investment delivers exactly the profile and species your project demands.

How do I choose between paint-grade and stain-grade millwork for my project?

Paint-grade materials like poplar offer excellent workability and smooth finish at lower cost, perfect when color rather than wood grain is the goal. Stain-grade species like oak or maple showcase natural beauty but require higher material grades and more careful installation to avoid visible defects.
