"After two wet seasons of water seeping through our basement walls, we finally called Oriole. The inspector came out, walked us through exactly what was happening with the drainage around the footer, and gave us a written quote the same day. No pressure, no upsell. The interior drainage system they installed has been dry through every storm since."

"We had a horizontal crack in our block foundation that two other contractors wanted to monitor for a year. Oriole's inspector told us it needed a carbon fiber strap repair now, explained the clay soil load causing it, and had a crew out within a week. Solid work, clean job site, and the paperwork for the transferable guarantee came in the mail exactly when they said it would."

"Our sump pump failed during a heavy rain last spring and we had four inches of water in the basement. Oriole replaced the primary pump and added a battery backup system the following week. The inspector was straightforward about what we needed and didn't try to sell us on a full interior system we didn't need. That kind of honesty means we'll call them again."

"We discovered significant mold growth behind drywall during a bathroom renovation and were worried about what was behind the rest of the basement walls. Oriole's team did the remediation and identified the moisture source — a slow seep along the cold joint at the base of the wall. They handled both the mold and the waterproofing in one coordinated job. No subcontractors, no handoffs."

"I was nervous about getting basement work done as a single homeowner — worried about being oversold or not understanding what I was agreeing to. The Oriole inspector sat at my kitchen table, drew out a diagram of my drainage issue, and explained every line on the quote. The crew was respectful, finished on schedule, and left the basement cleaner than they found it."

"We've had Oriole out twice — once for interior waterproofing when we bought the house and once for a sump pump replacement last year. Both experiences were consistent: accurate diagnosis, fair price, work done right. The lifetime guarantee transferred with the house when we bought it, and we appreciated that the company was still around to honor it."
