Our team provides slip-resistant sealer coats with fine grit, delivering warm, mottled patios for homes and sealed walkways for both residential and commercial projects. Backed by 12 years in business and our 2-year workmanship warranty, we've completed over 1,187 projects, from a single front porch to wraparound patios with matching walks.
From a light grind that opens the cream of the slab to the last sealer coat that locks the color in, our team handles every detail. Serving San Antonio Heights and neighboring Claremont, Diamond Bar and Norco, we test the stain on a hidden corner of your own slab first, because no two slabs take color the same way.
Call us today for a free estimate, and we will stain a test spot so you see the real color before we start.
What you can hold us to
Carol, steep drive below the San Gabriel Mountains, San Antonio Heights
A faded, blotchy back patio the owners wanted warmer without a full flake look
Investment and duration figures are estimates. Your written quote sets the final price and schedule.
Carol's back patio on a steep drive below the San Gabriel Mountains in San Antonio Heights was faded and blotchy, and the owners wanted it warmer without a full flake look. We cleaned and lightly ground the back patio, about 340 sq ft, laid a two-tone acid-free penetrating stain, UV-stable polyaspartic sealer, and added fine grit to the sealer for wet feet. Carol's patio was an estimated $2,200 to $3,600 and took an estimated 1 to 2 days. The result is a warm earth-tone patio that keeps its color through the foothill sun.
Acid stains react with the lime in the concrete to make permanent, mottled earth tones, while water-based stains soak in as pigment and offer a far wider color range. Acid stain colors run to tan, brown, terra cotta and soft blue-green, and the result never looks like paint. Water-based stains can match a house trim color, which suits stucco homes in Yorba Linda and Villa Park, but they fade faster in full sun unless the sealer is UV-stable.
| Finish | Color range | Look | Sun and wear |
|---|---|---|---|
| Reactive acid stain | Earth tones only | Mottled, variegated | Color is permanent, the sealer wears |
| Water-based or acid-free stain | Wide, includes grays and blacks | More even | Fades faster without a UV-stable sealer |
| Patio, porch or pool deck coating | Any flake or quartz blend | Textured coating | Toughest, hides cracks and stains |
The slab decides the final color more than the stain does, so a stained floor always varies with the concrete under it. Troweled, smooth areas take stain darker, patches and repairs take it lighter, and old sealers or paint block it completely.
That is why we test first. On older foothill slabs in San Antonio Heights and Claremont, decades of patching show through as lighter shapes, and a water-based stain hides them better than an acid stain does. Newer tract patios in Eastvale and El Sobrante usually take an acid stain evenly.
A stained patio typically takes an estimated 1 to 2 days, with most of the time spent on prep and drying.
The big risk is skipping the test spot. Stain cannot be taken back, so a color that comes up too dark across a whole patio means grinding it off.
Sealer upkeep is the ongoing cost of stained concrete, because the color lasts but the sealer on top wears. A UV-stable polyaspartic sealer lasts longest in Inland Empire sun, while the cheaper acrylic sealers sold at big-box stores typically need a fresh coat every year or two on a sunny patio.
Plan on a light clean and a fresh sealer coat every two to three years in full sun, sooner on walks with heavy foot traffic. Sweep grit off, wash with a neutral cleaner, and skip bleach, which dulls the sealer.
Stains suit light duty, not hot tires. Patios, walkways, porches, covered entries and light-duty interior slabs in casitas are the right fit, especially on Norco and Woodcrest ranch homes where an earth-tone patio suits the Western look.
Garages and driveways are the wrong fit. Hot tires lift a thin sealer, oil soaks through it, and the stained color under the tire paths wears to gray within a few seasons. For garages and driveways we install a coating built for the load instead, one Rated for tire contact heat from 140°F to 180°F under parked cars.
Staining and sealing a patio, porch or walk is estimated at $1,200 to $4,000 for 200 to 400 sq ft, and the slab condition, the number of tones and the sealer chemistry move the price most. Carol's back patio in San Antonio Heights, an estimated $2,200 to $3,600, sat in the middle with two tones and a gritted polyaspartic sealer.

| Job | Est. investment | Est. duration on site |
|---|---|---|
| Patio, porch or pool deck coating or stain (200 to 400 sq ft) | Est. $1,200 to $4,000 per area | Est. 1 to 2 days |
| Old coating removal by diamond grinding, before staining | Est. $800 to $3,000 per floor | Est. 4 to 8 hours |
| Interior slab floor with moisture barrier (coated alternative) | Est. $3,800 to $8,000 per floor | Est. 2 to 3 days |
An old painted patio typically adds an estimated $800 to $3,000 to grind the paint off before any stain can soak in.
The prices shown are estimates for stained concrete and remain subject to change. Your written quote after the test spot sets the final price and the schedule, and it depends on the slab's condition, the stain colors and the sealer you choose.
Our owner looks at every slab before we quote and will say plainly when a slab should be coated instead of stained. After 1,187 projects in 12 years across a 45-mile radius, our crews know how foothill and tract slabs take color. Every job carries our 2-year workmanship warranty against peeling, delamination and hot-tire pickup on the sealer. You also get Coating makers' product warranties, typically 5 to 10 years on professionally installed systems, passed through to you in writing for the sealer itself.
When the slab should stay uncoated indoors, consider polished concrete, and for a tougher outdoor surface, a textured patio and pool deck coating.
We stain and seal across Riverside County and the foothills, with patios in San Antonio Heights, Craftsman walks in Claremont and ranch patios in Woodcrest, plus Yorba Linda, Villa Park and North Tustin on our service area page.
For a stained driveway that would face tire load, owners pick driveway coating and resurfacing, and inside the house an interior concrete floor coating.
A patio of 200 to 400 sq ft is estimated at $1,200 to $4,000 to stain and seal, and your written quote sets the final price.
Most patios take an estimated 1 to 2 days, and the furniture can typically go back the next morning.
Plan on a fresh sealer coat every two to three years in full sun, with a UV-stable sealer lasting longest.
We do not recommend it, because hot tires lift a thin sealer, so we install a two-car garage floor, full flake polyaspartic or a similar coating instead.
Patches take stain lighter, so they still show, and a water-based stain or a coating hides them better.
We add fine grit to the sealer, so the patio grips wet feet around a pool or under sprinklers.
State law limits a home improvement deposit to $1,000 or 10% of the price, whichever is smaller.

Start to finish
We walk the slab with you, map cracks, joints and old coatings, and take moisture readings before a system is named.
The system, every coat and its thickness, the colors and the cure and return-to-service times arrive in writing.
The slab is diamond ground with dust control, cracks and joints are filled, and each coat goes down inside its recoat window.
We walk the cured floor with you, go over the care notes and tell you when cars or equipment can come back.
