Who We Are
Cornerstone Porta Potty is a single-city operator. We don't franchise or rebrand; we own and maintain every unit that leaves our yard. That means the person who delivers your porta potty rental is the same person who services it weekly and picks it up when you're done. You talk to us directly, not a call center. We keep a fleet of standard units with 60 to 70 gallon holding tanks, each about 44 by 48 inches on the ground, plus ADA-accessible models, deluxe units with flushable toilets, and restroom trailers ranging from 2 to 8 stalls. For construction sites that need roll-off dumpster rental, we handle those too. If you're managing a renovation, a festival, a farm operation or a disaster response in Lakewood, we can supply what the job requires.
The reason we stay local is simple. Lakewood changes. We know the neighborhoods, the permit offices, the terrain. A wedding in Applewood, 8.5 miles northwest, is a different logistics problem than a festival setup. We know which roads take a 60 foot delivery approach and which ones don't. That knowledge saves you time and money.
What We Do
We rent portable toilet rental by the day, week, month or event. Most construction sites use our standard porta potty rental, but we also stock deluxe flushable porta potty models and ADA accessible porta potty units. According to OSHA 1926.51(c)(1), a construction site with 20 workers or fewer needs one toilet facility; sites with 20 to 40 workers need one toilet seat and one urinal. We size your order to match those requirements and your actual headcount.
Septic service is core to what we do. Septic tank pumping keeps a residential tank functioning. A typical tank pumps every 3 to 5 years depending on tank size and household size. We handle grease trap pumping for restaurants and holding tank rental for temporary installations. Our technicians know the difference between routine maintenance and emergency calls.
Handwashing station rental matters on job sites. Per 29 CFR 1910.141(d)(2), washing facilities require soap and towels or a hand drying device; hand sanitizer alone doesn't meet code. We supply portable sinks with hot water, foot pumps and soap dispensers. On sites where employees apply paints, coatings or herbicides, OSHA 1926.51(f)(1) mandates washing facilities. We've got those covered. For temporary events and construction work, temporary fence rental keeps your perimeter secure and your site organized.
How We Work
Call with your job details. We ask how many people, how many days, what's the site access like, and when you need setup. We quote you the porta potty rental cost or dumpster rental cost in writing. If you need dumpster permit requirements research or placement advice, we walk you through it. We deliver on your schedule, service on ours (typically weekly for portable toilets under standard use), and pick up when you call it done. For Lakewood customers within five miles, we often handle same-day emergency calls. For customers in Golden, 9.2 miles northwest, or Littleton, 13.6 miles southeast, we schedule next-business-day service.
We maintain our own inventory. That means you're not waiting for a truck from across the state. It means we can swap out a unit if something goes wrong instead of leaving you stuck. It means our how often are porta potties cleaned answer is honest: weekly for standard use, more often if you need it and we can get there.
Why rent from Cornerstone Porta Potty?
We're local, we own our equipment, and we answer the phone. You get a real person, not a dispatcher reading a script. We've serviced job sites, weddings, county fairs and emergency situations across Lakewood for years, and we know the city inside out.
Do you deliver outside Lakewood?
Yes. We service Wheat Ridge, East Pleasant View, West Pleasant View, Applewood, Golden, Englewood, Arvada and Littleton. Distances vary, so delivery fees adjust. Call with your address and we'll quote the total cost.
What's included in a weekly rental?
One service visit per week, pumping and sanitizing of the tank, and restocking of toilet paper and hand sanitizer. Heavier use sites may need mid-week service; we can arrange that separately.
Can I rent a porta potty for an event?
Absolutely. We handle weddings, festivals, marathons and corporate events. Event restroom rental pricing is different from construction rental because the duration and usage pattern change. Give us your headcount and event length and we'll quote it.
What if I need multiple units?
Most jobs do. We can place several standard units on one site, pair a standard with an ADA accessible porta potty, or combine toilets with handwashing station rental and temporary fence rental. We've scaled projects from two units to twenty. Tell us the scope and we'll build the quote.
