Retaining wall construction in Fairfield CA - a wall that drains and stays put

Slope washing into your patio or an old timber wall leaning out? We build a block wall on firm ground with drainage behind it.

What goes into building a retaining wall in Fairfield?

Retaining wall construction in Fairfield means building a wall that holds back the soil on a slope, and whatever sits on top of it, so your yard stops creeping toward the house, the fence or the patio. Most of the work that decides how it holds up happens below ground, before you see a single block.

Most calls I get about retaining walls start with a slope that won't stay put. Dirt slumps onto the patio after every rain, an old tie wall is leaning out, or there's a strip of yard you never use because it's all hill. A wall fixes that by holding the soil back, and if what you really want is a freestanding wall along a property line, that's our concrete block walls work.

The price moves mostly with the wall's height and length, how much digging it takes, what we find at the bottom of the trench, how much drainage your site needs and how easy it is to get material into your yard. The schedule turns on whether your wall needs a permit and on getting underground lines marked before we dig. Your own figure comes from the estimate, once I've walked the slope and can tell you what's causing the problem.

  • Digging the trench and checking the soil at the bottom is firm before any block goes down.
  • A compacted gravel base, then dry-stacked concrete block set level, course by course.
  • Drain pipe and gravel behind the wall, and grading so surface water runs away from it.

What happens when you call about a retaining wall in Fairfield?

I come out to every retaining wall job myself, from the first look at your slope to the final walk-through. Here's how it goes from your first call to the day we pack up.

  1. Call or send a message

    Call (707) 398-2147 or use the form, and I'll get back to you to set a time to come look. Tell me roughly where the wall would go and how tall the slope is, so I know what I'm walking into.

  2. Walk the slope together

    I walk the area with you and explain what I see and what's causing it, whether that's water, soft ground or a wall that was never built right. You get an estimate for your wall and a clear sense of what drives the price, with no pressure to sign.

  3. We handle permits and build

    Once you say go, we take care of any permit the wall needs, keep you posted and meet the inspector. Then our small crew digs, builds and backfills, with me on site the whole way.

  4. Walk the finished wall

    Before we pack up, we walk the finished wall together so you can see the grading and where rain will run. Ask me anything you like, because I'd rather explain it twice than leave you guessing about your own wall.

How we handle retaining wall construction

Before the first block goes in, I plan where the drain line will run and make sure the bottom of the trench is firm, because trapped water and a soft base are the two things that push walls over. It's like stacking books on a mattress instead of a table, since the stack is only as steady as what's under it. Then we lay the base, set the first course dead level, stack the block with gravel behind it and backfill in layers. Before we call it done, I look at where surface water will run once the yard is finished, so it heads away from the wall instead of pooling at the top or the bottom.

A new wall tends to show up the tired masonry around it. If the brick steps, planters or garden walls next to your slope are crumbling, our masonry restoration work can bring them back while we're already there. And once a hillside turns into flat yard, some folks want somewhere to sit out at night, which is where our fireplace installation comes in.

  • Dry-stacked concrete block

    This suits most yard slopes, because the block's own weight holds the soil back and water can drain out through the face instead of building up behind it. The concrete masonry trade group says these blocks resist cracking, and it's what I'd point most people toward.

  • Timber or railroad ties

    Some people like the look of wood or have an old tie wall they want to match. The same trade group notes block holds up without the splintering and decay that wood faces, so if you're replacing a rotting wall, I'd go with block.

Retaining wall questions from Fairfield homeowners

These are the questions I hear most when I'm standing on someone's slope in Fairfield. If yours isn't here, ask me on the walk-through and I'll explain it right there.

How much does a retaining wall cost in the Bay Area?

Retaining wall construction in the Bay Area usually costs about $50 to $65 per square foot. That's the going rate across the area, not our price, and where your wall lands depends on its height, the digging and the drainage your site needs. I'll give you your own figure at the estimate, and the work is backed by our satisfaction guarantee.

Does my retaining wall need a drain pipe?

It does if it's a reinforced wall, a gravity wall over 4 ft tall or a wall on a site with poor drainage, according to one block maker's install guide. A reinforced wall has grid layers tied back into the soil, while a gravity wall holds the slope with the block's weight alone. If your yard stays soggy after rain, plan on a drain pipe as part of the build.

What is the best way to build a retaining wall on clay or wet soil?

Dig out the bad soil and replace it with compacted gravel fill, because one block maker's guide says the bottom of the base trench has to be firm and solid. That goes for heavy clay, wet soil and ground that's been dug up before. It adds digging and fill to the job, so it's one of the first things I check at the estimate.

Can an unlicensed handyman build a retaining wall in California?

Usually not, since California's minor work exemption only covers jobs up to $1,000, and only when the work needs no permit and the person has no employees. A wall that needs a permit falls outside that exemption no matter the price. We're fully licensed and insured, so that's one less thing for you to sort out.

How do I get underground utilities marked before building a retaining wall?

Call 811, the Call Before You Dig service every state has, and underground utilities get marked a few days before digging. Book it well ahead of the start date so the marking doesn't hold up the dig. We plan our start around it.

Are block retaining walls safe in an earthquake?

They've done well when they were designed for it, since the concrete masonry trade group reports segmental walls proved more robust than conventional retaining walls after earthquakes when properly designed for those forces. That condition is the part that matters, so it's worth talking through when we go over your wall.

Retaining wall construction in Fairfield and nearby cities

Fairfield's Building Division issues grading permits for single-family homes, and city right-of-way or easement work needs an Encroachment Permit, so I check with the city and apply for whatever your wall needs. We build the same walls in Vacaville and Suisun City.
