What stone Restoration covers
Stone restoration covers cleaning, repair and selective replacement of architectural stonework such as sills, steps, cornices and door surrounds. The main risk is over aggressive cleaning, which removes the weathered outer skin and leaves the stone more absorbent than before.

Cleaning, repairing and replacing architectural stone without damaging the surface you are trying to save.
Waystar carries out this work on residential and commercial property in Brooklyn and across New York City. Every project starts with a look at the building, and the scope, the materials and the figures are written down before anything begins.
When might you need it?
These are the signs owners usually notice first.
- Soiling and staining across stone detail
- Eroded arrises and lost edges on steps and sills
- Open joints between stone units
- Previous cement repairs standing proud and cracking
- Cracked or displaced individual stones
What the work involves
- Stone type identified before any cleaning method is chosen
- Cleaning trials on a discreet test area
- Gentlest effective cleaning method used across the work
- Failed cement repairs removed
- Repairs made in a matched, softer mortar
- Individual units replaced or turned where loss is severe
How the process works
Identify the stone
Method depends entirely on stone type, and getting it wrong causes permanent damage.
Trial the cleaning
A test area shows what works before anything is committed across the elevation.
Remove failed repairs
Hard cement patches usually have to come off first.
Repair and match
Softer matched repairs are formed and the profiles reinstated.
What you get
- Cleaning that does not strip the protective outer surface
- Repairs matched in colour, texture and hardness
- Detail recovered instead of simplified
What affects the scope
- Stone type and how sensitive it is to cleaning
- Extent of soiling and what has caused it
- How much moulded detail has to be reformed
- Whether any units need full replacement
This is a preliminary planning range, not a quote. A property visit is required before any price is confirmed.
Frequently asked questions
Can the stone be pressure washed?
Rarely at any real pressure. High pressure strips the weathered outer skin and leaves the stone more absorbent than it was.
Will cleaning make it look new?
It should not. The aim is to remove soiling while leaving the stone reading its age, not to bleach it back to raw.
Should stone be sealed afterwards?
Usually not. Most sealers reduce breathability and trap moisture in a material that needs to dry outward.
