Ontario is mostly flat, and that changes what a retaining wall is for. In neighborhoods like the 91761 ZIP code, most walls are low borders along driveways, planters against the house, and small grade changes between yards, not the tall hillside walls you see up in Riverside's Canyon Crest.
We get called to Ontario because those low walls still fail. Old block along a driveway starts to lean, a planter wall cracks and bulges, or winter rain washes out the soil behind a wall that never had proper drainage. Our team knows the housing stock here, from the older tracts near Euclid Avenue to the newer developments off Milliken, and we fix the wall and the water problem behind it.
Retaining Wall in Ontario (91761)
Ontario sits on mostly level ground, so the retaining walls here are usually short: 1 to 3 feet of block or timber holding a raised yard, a driveway edge, or a planter bed. The soil is often sandy and drains fast, which sounds good until you see what happens when a wall has no weep holes or the drainage rock behind it is clogged with fines. Water builds up, the block bows, and a wall that looked fine in July is leaning by February. We also see a lot of aging block walls from the 1970s and 1980s, especially around older neighborhoods near the 60 freeway and along Holt Boulevard, where the original mortar is tired and the footing was never designed for today's runoff.
Our team has worked walls all over the Riverside area, from the granite slopes of Hawarden Hills to the flat grid of the Wood Streets, and we bring that experience to Ontario. We know how to read a small lot, work around tight driveway access, and build a wall that handles the inland heat and the occasional hard winter storm without asking for much maintenance.

How a Job Works in Ontario
Step 1: You call (951) 425-4346 or send us a message. We schedule a free on-site assessment, usually within a couple of days. We walk the property with you, look at the wall, check the drainage and the soil, and talk through what you want. You get a written estimate with a clear scope, not a ballpark over the phone.
Step 2: Once you approve, we pull the permits if your wall needs one (in Ontario, walls over about 4 feet from the footing or walls that hold up a driveway or structure usually do, and the city building department has the final say). We schedule the work, protect the access, and keep the site as tidy as we can. On tight lots off streets like Bon View or Grove, we plan material delivery and spoil removal so we are not blocking your neighbor's driveway.
Step 3: We clean up, haul away debris, and walk the finished wall with you. You get a chance to ask questions, and we do not leave until you are satisfied with the grade, the drainage, and the look of the wall.
Pricing in Ontario depends on the wall. A small block or timber border wall often starts around $20 to $25 per square foot, while a concrete wall runs closer to $35 per square foot. Repairing a leaning or cracked wall typically starts at $1,500, and a full replacement of a failed wall starts around $35 per square foot. Drainage work, which is often the real fix behind a failing wall, starts at $2,500. The biggest cost factors are the size of the wall, how tight the access is, the condition of the soil and footing, and how quickly you need it done. Call (951) 425-4346 for a free estimate that fits your actual property.
