Retaining Walls

We build everything from short timber walls under 4 feet to engineered walls well past 8 feet. For 3 to 8 foot residential heights, segmental concrete block is our workhorse; once you get into 8 foot-plus or surcharge conditions from a driveway, pool, or structure above the wall, we switch to poured concrete so the design isn't over-engineered. Any wall over the local height threshold gets stamped engineer's drawings as part of the job.

Drainage is the single biggest variable in how long a wall lasts. Without weep holes and a free-draining stone layer behind the wall, hydrostatic pressure builds after every wet season and the wall starts to bow outward. Every job we build includes weep holes and a French drain behind the wall, backfilled with free-draining stone before the final soil cap, because we've replaced 12-year-old walls that should have lasted 40 and every one had failed drainage.

It comes down to look, budget, and timeline. Segmental concrete block is the fastest install for 3 to 8 foot heights, comes in a wide range of colors, and runs a mid cost tier, though it reads as engineered and can fade after 15-plus years. Natural stone is the best aesthetic match for waterfront, patinas with age instead of fading, and gives the highest property-value lift, but it's hand-fit work so it installs slowest and prices at a premium.

Treated timber is the budget-conscious option for short walls under 4 feet on rural lots, where it's the lowest material cost and quick to install. We don't recommend it within 5 feet of standing water, because wet-dry cycling eventually rots the grade-contact members. Expect 15 to 25 years of life versus 40-plus for block and 50-plus for stone, so on a permanent feature near the house we usually steer people to block or stone.

Less than most people expect if it's built right. Segmental block needs only an annual visual inspection of the drainage outlets. Natural stone wants the joints re-pointed every 15 to 20 years and the drains cleared annually. Timber is the highest-maintenance choice: inspect grade-contact members every 5 years and replace any failed timbers early before the failure spreads.

The main drivers are wall height and total linear footage, the material you pick (timber, concrete block, or natural stone), the soil type and hydrostatic pressure behind the wall, the drainage system required, and site access including proximity to structures or utilities. We give a free on-site assessment with soil and drainage evaluation, then write a firm number against your actual conditions rather than a per-foot catalog rate.

The construction itself moves quickly once we're on site, with block walls being the fastest install in the 3 to 8 foot range and hand-fit stone the slowest. The bigger schedule driver is approvals: if you're in a covenant-controlled neighborhood, HOA architectural review is usually the slow path since boards meet monthly, so plan an extra 30 to 45 days for that submittal. We pull the county permit and handle the engineering as part of the job.

Yes, and bundling saves money while we have a crew mobilized. When a wall sits within 5 feet of water we pair it with a bulkhead toe so the base can't be undercut. We can re-grade the reclaimed waterline behind a finished wall using on-site dredge spoils, and tying dock framing into a finished retaining wall is cheaper while our crew is already there. Licensed and insured since 2012, we coordinate the whole package under one contract.
