Slate Cleaning, Sealing and Repair - Philadelphia & the Delaware Valley

Reveal the Rich Color & Natural Texture of Your Slate Again

Slate is a unique natural stone known for its rich color variations, layered texture, and durability. However, exposure to moisture, foot traffic, improper cleaners, and environmental elements can cause slate to fade, stain, flake, or lose its natural vibrancy. At Facility Specialists, we provide professional slate cleaning, repair, sealing, and restoration services throughout the Philadelphia & Delaware Valley.

Whether your slate floors, showers, entryways, fireplaces, or outdoor spaces look dull or worn, we restore them to a clean, protected, and naturally beautiful finish.

Common Slate Problems We Repair

Slate is durable, but its layered structure creates unique challenges. We restore and resolve issues such as:

Faded or uneven color
Embedded dirt & residue buildup
Flaking or surface delamination
Stains from moisture, oils, or soil
Cracks, chips & broken tiles
Worn or missing grout
Uneven surface texture
Dull or lifeless appearance
Water darkening and moisture absorption

Our restoration process improves both the appearance and performance of slate surfaces.

Our Slate Restoration Process

Surface Evaluation
We assess the slate type, finish, degree of wear, and moisture exposure to determine the right treatment approach.
Deep Cleaning
We use stone-safe cleaners and controlled agitation to remove embedded soil, residue, and contaminants without damaging the slate layers.
Repair & Stabilization
Cracked, chipped, or flaking slate is repaired and stabilized to prevent further deterioration.
Grout Cleaning & Repair (If Needed)
We clean, repair, or regrout joints to restore a clean, uniform appearance.
Sealing or Color Enhancement
We apply either:
– Natural penetrating sealers for a matte look, or
– Color-enhancing sealers to deepen slate’s natural tones and contrast
Final Detailing
The surface is detailed for a clean, even, and protected finish that is easier to maintain.

Did You Know?

Slate is a layered stone, which is why it can flake when exposed to moisture without proper sealing.
Color-enhancing sealers can dramatically restore slate’s original richness without creating a glossy finish.
Many slate surfaces fail prematurely due to pressure washing or acidic cleaners, which damage the layers.
Properly sealed slate is significantly easier to clean and resists staining and moisture absorption.
