West Seattle repair loose retaining wall blocks
Homeowner’s Issue
West Seattle yards face specific pressures that make retaining walls fail: seasonal heavy rains, compacted urban fill, and steep lots around Admiral, Alaska Junction, and up toward High Point. Many walls were built on glacial till or mixed fill and sit above clay lenses that hold water. When the rainy season runs, poor drainage and perched water push on blocks; meanwhile moss, English ivy, and blackberries add root pressure and hide shifting courses until blocks are noticeably loose.
Sun exposure varies block-by-block — Alki-facing slopes get salt and wind, while properties near Lincoln Park sit shaded and mossy. HOA and neighborhood curb-appeal expectations in West Seattle mean visible bulges or leaning courses can trigger notices. Drainage problems from upstairs neighbors or clogged downspouts commonly show up as saturated backfill behind a wall, causing movement.
Owners often delay repairs because the work looks small. Left alone, a handful of loose blocks turns into undermined footings and a larger, more expensive rebuild. We focus on practical, sustainable fixes: re-leveling blocks on free-draining aggregate, improving drainage, using geotextile where needed, and removing invasive roots by hand — all without herbicides. This local approach reduces repeat visits and keeps yards stable through the next big storm cycle.
Our Quality Service
We diagnose the real cause — not just reset a block. That means a visual inspection, probing backfill, and testing drainage lines. For simple resets we remove, clean, and re-bed each block on crushed rock and compacted base; for bigger jobs we install perforated drain tile, gravel backfill, geotextile, and hand-tie courses when appropriate.
Tools and methods are practical and low-impact: compactors, wheelbarrows, hand tools, and aggregate deliveries. We avoid chemical herbicides — invasive plants get cut and dug out, and we use organic weed control or landscape fabric where needed. Typical timelines: a small section (5–15 blocks) in one day; larger sections or drainage installs 1–3 days. We carry green-waste bins and can haul debris to transfer stations or load for city green-bin composting.
Benefits: safer slopes, better curb appeal, reduced maintenance, improved drainage, and longer-lasting walls tailored to West Seattle conditions.

Before & After / Expectations
Be realistic: work is noisy for a day, dusty, and may block narrow access. Heavy blocks may require extra hands or a small skid; tight Seattle alleys sometimes need extra staging time. We handle debris removal — choose haul-away or city green-bin composting.
After repair, expect a short settling period. Check drains after the first big rain. If plantings are added, water deeply but infrequently to encourage roots without saturating backfill. For West Seattle yards: remove moss and ivy regularly in shaded spots, and check downhill drains after heavy rains in November–March. We never use herbicides; invasive roots are removed mechanically and replaced with low-maintenance natives where possible.
FAQs
Q: How long will a typical repair take?
A: Small resets: one day. Drainage upgrades or longer walls: 1–3 days depending on access and scope.Q: Will work disturb my yard?
A: Expect noise and some soil movement. We protect lawns and hardscape and clean up daily.Q: Do I need permits?
A: Minor resets rarely need permits, but significant regrades or tall wall rebuilds may require city or HOA approval. We’ll flag permit needs in our inspection.Q: How do you control weeds without chemicals?
A: We hand-pull invasives, apply organic weed-control where needed, lay fabric under mulch, and recommend low-maintenance groundcovers to suppress regrowth.
