Deep Pressure Washing
We used our professional pressure washing equipment to deep-clean all 1,840 square feet of limestone pavers, removing surface dirt and organic buildup before the brightening treatment.

PROJECT CASE STUDYWe cleaned, brightened and sealed 1,840 square feet of white limestone pavers in Scottsdale, AZ. Our one-day project included deep pressure washing, a specialized brightening treatment to address brown discoloration and organic buildup, and two coats of penetrating sealer.





We deep-cleaned 1,840 square feet of white limestone pavers with our pressure washing equipment, followed by a second cleaning using our specialized brightening solution to address brown discoloration and organic growth. We finished with two coats of penetrating sealer. The one-day project cost $3,220 ($1.75 per sq. ft.).

White limestone pavers can develop stubborn brown discoloration and organic buildup outdoors, making the original light color difficult to restore. For this Scottsdale project, we used more than standard pressure washing: a second, specialized brightening treatment helped bring the stone back toward its natural white appearance before sealing.

We completed this Scottsdale limestone project in one day using a two-stage cleaning process followed by two coats of penetrating sealer.

We performed a second cleaning with our specialized limestone brightening solution to address stubborn brown discoloration and help restore the white limestone's original appearance.
After the deep cleaning and brightening treatments, we prepared the limestone for the penetrating sealer application.
We applied the first coat of penetrating stone sealer to help protect the porous limestone against moisture and everyday staining.
We followed with a second coat of penetrating sealer for additional coverage. The treatment helps protect the stone without creating a thick topical coating; sealing does not make limestone stain-proof.

The challenge was restoring the light appearance of white limestone affected by brown discoloration and organic growth. We used deep pressure washing followed by our specialized brightening solution to help bring back the natural white color.

We applied two coats of penetrating sealer after cleaning and brightening. Penetrating sealers help protect porous limestone against moisture and staining without forming a heavy surface film. We completed all 1,840 square feet in one day.
