Historic Masonry & Stone Restoration

Brick, stone, concrete restoration without water damage or chemical staining.

When a deadline, deal, or safety situation is on the line, RayVault responds fast.

Mobile, chemical-free laser cleaning for mold, graffiti, oil spills, and biohazard decontamination — priority response throughout Portland and the Pacific Northwest.

Restoring History Without Compromise

Portland's historic buildings are irreplaceable. Traditional methods — sandblasting, chemicals, pressure washing — damage porous stone long-term. Our laser targets only the contaminant, leaving original stone, patina, and texture completely untouched.

Applications & Surface Types

We handle historic facade restoration, graffiti removal without ghosting, paint and coating removal, biological growth elimination, fire damage restoration, and mortar residue cleaning. We serve preservationists, architects, building managers, and municipalities across Portland.

Common Questions About Laser Cleaning for Stone & Masonry

Will laser cleaning damage the surface of my historic brick or stone?

No. The laser is absorbed by the contaminant, not the stone — leaving original texture, tool marks, and patina completely intact.

Can laser cleaning remove graffiti without leaving a shadow or ghost mark?

Is laser cleaning safe for mortar joints and detailed carved stonework?

Trauma Scene & Biohazard Surface Decontamination

We understand that some situations go beyond standard cleaning. Our laser ablation process fully decontaminates surfaces affected by trauma or biohazard events — including biological material — at both the surface and pore level, without chemicals, without cross-contamination risk, and without leaving residue. We respond with discretion, professionalism, and genuine care for everyone involved.

Trauma Scene Decontamination

When a traumatic event has occurred, surfaces need more than cleaning — they need full decontamination. We remove biological contamination from concrete, wood, metal, and masonry thoroughly and without chemical residue, so the space can be restored properly.

Biohazard Surface Treatment

For surfaces requiring certified-level decontamination, our laser process vaporizes hazardous biological material at the surface and within porous substrates — no liquid waste, no chemical introduction, no residue left behind.

Discreet & Documented Response

We work quietly, respectfully, and on your timeline. Unmarked vehicle options are available, and we provide post-treatment documentation for insurance, legal, or compliance needs as required.
