After the winter rains, our Laurelhurst basement started showing cracks. Portland Foundation Repair explained everything clearly, showed up on time, and stabilized the wall without turning our yard into a mess. The crew was respectful, organized, and genuinely cared about protecting our home. I’d recommend them to any Portland homeowner.

Our crawl space in Sellwood had sagging floors and moisture problems, and I wanted answers, not sales pressure. Their team inspected the piers, walked me through the repair plan, and completed the work efficiently. The floors feel solid again, and the cleanup was better than expected for a dirty job.

We own a bungalow near Mt. Tabor, and foundation issues felt overwhelming until this crew arrived. They were patient, friendly, and worked around our schedule, even during typical Portland drizzle. The finished repair looks clean, the basement feels drier, and communication stayed excellent from estimate to the final walkthrough appointment.
