Stone for Life
We restore marble, travertine, and natural stone to a standard its original craftsmen would recognize. Our work is built to last — and if it ever falls short, we make it right.
About Crystal Service
Crystal Service was built on a simple belief: natural stone deserves to be treated with the same precision and respect it took nature millions of years to create. Founded by Sandro Tsaava in North Bethesda, Maryland, we specialize exclusively in natural stone restoration across the DMV.
We use professional-grade diamond tooling, multi-stage grit sequences, and crystallization-grade compounds not available to general contractors. Every job is backed by our Lifetime Results Guarantee — if it isn’t right, we come back and fix it at no charge.

What We Do
The Difference
Transparent Pricing
Every estimate is free and written. We assess your stone, tell you exactly what it needs, and provide a firm price before any work begins.
Our Promise
“We don’t consider a job finished until the result matches — or exceeds — your vision of what it should be.”
Stone for Life means exactly that. If something we restore ever fails due to our workmanship — if it doesn’t meet your vision within reason — we come back and fix it. Free of charge. No negotiation. No fine print.
This guarantee isn’t a marketing line. It’s the standard we hold ourselves to on every job, from a bathroom floor in Bethesda to a hotel lobby on K Street.
Our Work
What Our Clients Say
“Our marble floors look better than they did the day we moved in. Sandro was meticulous, professional, and the result genuinely exceeded what we thought was possible. We’re on the maintenance plan now and wouldn’t use anyone else.”
