A driveway is the one slab a car parks on, and it shows

Everything that leaks out of a vehicle lands in the same few square feet.

Engine oil, transmission fluid, power steering weep and tire rubber all end up on the same strip of concrete, and concrete is porous, so none of it stays on the surface. It wicks down into the slab. Then from roughly May to November we get no rain to rinse anything off, so a drip that lands on a hot Paso Robles or Santa Maria afternoon has months to soak in and cure before winter ever touches it. That is why a driveway that gets washed once a year comes clean and one left for six years never quite does.

Most driveways here are really two driveways. The half in open sun bakes dry by mid morning. The half under a live oak, or on the north side of the house, stays damp, and in Los Osos, Cambria, Cayucos and Morro Bay the marine layer holds that damp past noon for much of the year. That shaded half goes green, then gray, then black. It is not a stain, it is growing, and it turns slick underfoot on the sloped hillside driveways around San Luis Obispo. If growth keeps returning after a wash, that is a drainage and light problem and it lives on our mold and algae page.

Then there is whatever your particular slab gets fed. Sprinkler heads throwing onto the edge of the concrete leave a chalky calcium bloom inland where the water comes off a well, and where that water carries iron they leave orange fans that are rust and want different chemistry than dirt does. Harvest traffic through Paso Robles and the Edna Valley kicks up dust every autumn that overnight dew turns into a film. Driveways off the Highway 101 corridor collect road film that tires carry up the slab and lay down in two dark lines.

How the slab actually gets cleaned

Our crew, our equipment, every time. Nothing is handed to a subcontractor, so the person who priced your driveway is the person walking it with a surface cleaner.

  1. We read the slab before the water goes on

    We walk it and mark the drips, the tire scuff at the top where wheels turn in place, the shaded section, any spalling, cracks or old sealer. Existing damage gets pointed out to you first, not discovered later. We also work out where the rinse water is going to run.

  2. Degreaser first, pressure second

    Oil is in the concrete, not on it. Hitting a drip with pressure straight away drives it deeper and burns a bright halo around it. Degreaser goes on, gets time to pull the oil back up, gets agitated with a brush, and only then does it get cleaned off.

  3. Surface cleaner, straight lines, even overlap

    A surface cleaner sits flat on the slab inside a shroud and cleans a fixed width. We run it in straight passes at one steady walking speed with the same overlap every time. Waving a wand instead is what leaves the zebra striping you only notice once it dries.

  4. Edges, joints and the apron by hand

    The shroud cannot reach the last inch or two against the garage door, the walls, the expansion joints or the flare where the driveway meets the street. Those get detailed by hand. The apron is the darkest part of the slab and the part your neighbors actually see.

  5. Flood rinse, then the walk around

    Everything the surface cleaner lifted gets rinsed off the slab and out of the joints before it can dry back down. Then we walk it with you. Anything you are not happy with gets put right there and then, and we tell you honestly what a stain will look like dry.

What is included

  • The full slab edge to edge, not just the section with the stain on it
  • The apron at the street, where the road film off Highway 101 gets tracked in
  • Surface cleaner passes overlapped in straight lines so the concrete dries even, with no wand stripes
  • Degreaser worked into oil, transmission and power steering drips and given time before any pressure touches them
  • Tire scuff and turning marks, including the brown plasticizer halo under a car that parks in the same spot all summer
  • Extra passes on the shaded and north facing half where the organic film sits thickest
  • Edges, expansion joints and the strip against the garage door detailed by hand
  • A walk around with you before we pack up, with a straight answer on how each stain will look once it dries

What we do not do

Worth saying plainly, so nobody is waiting on something we were never going to do.

  • Sealing, staining or coating the concrete afterwards. We clean it, somebody else seals it.
  • Crack repair, resurfacing or lifting a sunken section. That is a concrete contractor, and we will say so.
  • Patios, pool decks and walkways. Those are on the concrete cleaning page, and we are glad to quote them on the same visit.

The light literally shines brighter

Every word below is lifted straight from Corey's Google profile. Nothing written by us, nothing tidied up.

Crystal Clean was at our house this morning to clean all the windows on the first and second story and did a wonderful job. Corey is a perfectionist and is very detail oriented. He cleaned the windows inside and out, cleaned the screens, cleaned the tracks, and even all the window sills.

Had our windows and solar panels cleaned. WOW! I keep looking out the windows because I can't believe how clean they are. Corey's team is fast and hard-working, too. We are so glad we had this done!

Corey and his crew are just amazing. On time, fast, great price and a stunning outcome! Terrific communication ahead of time. After he cleans our windows, the light literally shines brighter. Love it!

Cory and team did a fabulous job on our Cayucos Beach house window cleaning, inside and out. Our house looks brand new again! Very responsive and easy to work with. Great price as well. We will definitely use them again.
Kristin OlsonCayucos · Beach house window cleaning2 years ago
The best!!! On time, very confident and considerate inside our home as well as outside. Corey and his son are very professional at what they do. 2 objectives we needed done. 1 very hard to reach interior skylight and our solar panels needed cleaning. We will definitely have them back on a yearly maintenance plan for sure.
Jim & Sandy ClarkGrover Beach · Skylight, solar and gutters3 years ago
Communication was top shelf. Timely, arrival and departure. Fairly priced to local competition. Professional, beginning to end. Ran a clean operation, wore booties over shoes inside without asking, never noticed they were here after they left due to picking up after themselves. Our 3 story home was no easy task but they managed to clean all of our 27 windows just fine.
Marc G3 story home, 27 windows5 years ago
If I could give Crystal Clean 10 stars, I would! My pergola was extremely dirty and moldy as my home power washing attempts could never get it clean. I was considering taking it down it was such an eyesore. It now looks brand new without a trace of mold to be found!

Cory was responsive from our very first contact, always following up and showing up. And our windows are literally sparkling, which I thought was just a phrase. The company uses soft water which reduces water stains.

Crystal Clean A1 has cleaned the solar panels on our house and HOA pool house twice now. Both times they were easy to communicate with, arrived as scheduled, and did a thorough job for a reasonable price. They're an easy company to recommend.
Matthew BudraitisResidential and HOA solar2 years ago
I've never seen my windows so clean!! Not only did they clean all our windows but our screens, solar panels and gutters! Very professional and fast! I would definitely use again and recommend you do too!
Melissa MudgettWindows, screens, solar and gutters5 years ago
Corey has cleaned probably close to 20 houses of windows and solar panels and a driveway or two. I have always been more than satisfied with the work and he always goes above and beyond for a fair price.
Aaron RobertshawWindows, solar and drivewaysa year ago
Cory was the ultimate professional. Great communication, timeliness and did an amazing job! I cannot recommend him highly enough. This is my second time using his services and I would highly recommend him, you will be pleased.

Excellent work cleaning my homes windows. This is the second time I have had this company out and they have once again exceeded my expectations. I will continue to be a return customer.
Kaelan ClarkRepeat customera year ago
Double glaze window cleaning perfection. At last a window cleaning company that really provides service. Timely and professional. Most window companies fall apart after first visit. For now 10 out of 10. Look no further, you found it.

What driveway cleaning costs around here

Across the Central Coast, driveway washing generally runs somewhere around $0.15 to $0.35 per square foot, which puts a standard two car driveway roughly between $120 and $300, with long rural drives out toward Creston and Templeton well above that. Heavy oil work is usually priced on top. Those are regional ranges to set expectations, not our quote. Send the address and a rough length and you get a real number.

  • Square footage, measured, not guessed

    A two car apron and a 200 foot ranch drive are the same service and nothing like the same price. We price off the actual area, including the apron at the street.

  • How long since the last wash

    A slab cleaned last year needs one pass. A slab that has not been touched since before the last drought needs two or three, plus dwell time, and that is mostly labor.

  • Oil and fluid staining

    Fresh drips come off in the normal pass. Old stains need degreaser, dwell time and a second run, so the count and the age of the stains move the number more than anything else on the slab.

  • Surface finish

    Broom finish is straightforward. Stamped, exposed aggregate and pavers take longer and want a gentler approach, and pavers may need their joint sand topped up afterwards.

  • Slope and where the water ends up

    Hillside driveways in San Luis Obispo run everything downhill, sometimes at a garage door. Anywhere the rinse needs containing before it reaches a storm drain adds time.

  • Water access

    A working spigot near the slab is easy. Rural properties on a well, low pressure lines and long hose runs from the back of the house all add setup.

No obligation, no pressure, no call center

We Guarantee 100% Satisfaction

Every job finishes the same way: a walk around with you before we pack up, so anything you are not happy with gets put right there and then. Corey Byler is the one doing that walk around. Business License #17881, insured to $1,000,000, and no part of the job handed to somebody else.

Driveway Cleaning questions we get asked

Will pressure washing remove old oil stains from a driveway?
Pressure washing removes most of a fresh drip and a good part of an old one, but rarely all of a stain that has been there for years. Oil soaks down into porous concrete rather than sitting on top of it, and on the Central Coast we go May to November with no rain, so a summer drip cures deep into the slab. The right approach is a degreaser applied and left to pull the oil back up, agitated, then cleaned off, sometimes twice. An old stain usually lightens to a faint shadow instead of vanishing. Anyone promising a guaranteed total removal on a six year old stain is guessing.
Can you clean just the stained part of my driveway?
Crystal Clean A1 can do that, but it will look worse than leaving it alone. Concrete lightens wherever it is cleaned, so a washed patch inside a dirty slab reads as a bright rectangle with a hard edge around it, and the eye goes straight to it. The correct minimum is edge to edge, or at the very least from one control joint to the next so the line falls somewhere the slab already has a line. That is also why the apron at the street belongs in the job. Clean the driveway and stop short of the street and the dirty flare is the first thing anyone sees.
Why does my driveway have stripes after it was washed?
Stripes left on a driveway after washing are wand stripes, and they come from someone cleaning with a pressure wand waved side to side instead of using a surface cleaner. A wand throws a fan pattern that cleans in arcs, so wherever the arcs overlapped the concrete came out lighter, and wherever they did not it stayed darker. It looks fine while the slab is wet and shows up an hour later once it dries. It does not wash off. The fix is redoing the whole slab with a surface cleaner run in straight overlapping passes at a constant speed so the concrete dries at one tone.
The shaded half of my driveway is black and slippery. What is that?
The black slick is living growth, not dirt: algae and lichen feeding on moisture that never gets a chance to dry off. North facing concrete and anything under a live oak or a Monterey pine holds damp, and in Cambria, Los Osos, Cayucos and Morro Bay the marine layer keeps it damp well past mid morning for much of the year. That is why it is slick when it is wet and why it stops at a hard line where the sun starts. Cleaning takes it off the surface. If it returns within a season, the real fix is more light or better drainage.
How often should a driveway be cleaned on the Central Coast?
Once a year suits most properties, and twice a year makes sense if you have heavy tree cover, a north facing slab, or you are within a few miles of the water where the fog keeps concrete damp. Nothing self cleans here between May and November because there is no rain to rinse the slab, so dirt just accumulates. Autumn is a good window inland, after the harvest dust through Paso Robles and the Edna Valley has settled. It is also worth doing before you list a house or before anyone seals the concrete, since sealer locks in whatever is underneath it.
Do you clean the edges and the apron at the street?
Yes. Corey Byler counts the edges and the apron at the street as part of the job rather than an add on. A surface cleaner runs inside a shroud, so it physically cannot reach the last inch or two against the garage door, the walls, the expansion joints or the curved apron at the street. Those strips get detailed by hand. A dark border left around a clean slab is the clearest sign a driveway was rushed. The apron matters most because every vehicle drags road film across it, so it is usually the dirtiest concrete on the property and the piece visible from the road.
