Is Your Job Site Prepared for the Summer Heat?

3 Tips to Ensure Your Construction Site Stays Fresh this Summer 

Working on a construction site can be especially tough in the hot summer months. With temperatures pushing towards 100 degrees not only is it hard to stay cool, it is also hard for construction managers to keep job sites fresh and odor free. While each site might be different, there are a few tips and tricks you must know to help keep your construction site fresh this summer!

Here are three easy ways to keep your site fresh during the dog days of summer:

    1. Additional Weekly Servicing – At Don’s Johns, we take pride in our once a week restocking, waste removal and unit sanitization that comes with each standard unit. However, in the summer heat, it is necessary for additional servicing to reduce odor and keep the job site clean. If our uniformed technicians come out at least once more per week, job sites are essentially odor free during the hottest months of the year.
    2. High-End Holding Tank Deodorizers – There is the standard, blue solution deodorizer that is seen in most porta potties, which get’s the job done in the cooler months of the year. In the summer though, we recommend going with the higher end deodorizer chemical paks by Walex. We have found that this deodorizer pak has performed the best in the extreme heat and is the most powerful in our industry.
    3. Air Freshener – Our last suggestion is a simple but effective solution. By placing air fresheners in your porta potty units you will be able to not only minimize odors but also keep them smelling great! Air fresheners will keep the port-a-potties bearable in between servicing during the hot summer months.  If you use us, that is a standard part of our service, every week!

6 Tips to Maximize Productivity on Your Construction Site

The statement ‘time is money’ definitely applies to the construction industry. Whether it’s a loss of equipment or an inefficient use of your employees, your project’s deadline could be missed by weeks to a month. To ensure you are maximizing your productivity, follow these six tips.

Plan for Everything

The most expensive part of most construction projects is improper planning. There are too many predictable things that can happen that can cost your project a fortune. Before bringing anyone on site, plan for those minor details to avoid a major catastrophe. This keeps your project on schedule by ensuring you will have the proper manpower, supplies, and equipment every step of the way.

Optimize Your Crew

It’s understandable that you have particular crew members trained for specifics on the job. To remain up to code, they should do what they are trained for. However, there are a few non-certified activities that anyone can perform during their downtime. Be sure to speak to your entire crew about remaining productive, be it training another individual or cleanup at the construction site.

Use Storage Containers

Storage containers are not just meant to keep outdated items out of the way. You can rent temporary storage containers for each construction project you work on to keep a clean and organized site. Rent storage containers to keep any waste at bay.  Order your materials ahead of time and store away in case your project is ahead of its timeline. Your items will be there ready to implement into the next phase.

Implement New Technology

Every organization should embrace new technology. It improves workplace performance, saves time, and reduces costs. It is scary for some employees that have been on the job for a number of years to embrace any change. However, with proper training they can see how technology is not there to replace them but make their jobs easier at your construction site.

Track All Your Equipment

Can you recall how many times your employees have lost equipment or unfortunately borrowed equipment? It’s easy to keep track of all your equipment, tools, and other materials by adding an inexpensive GPS tracker on them. Mistakes do happen, and it should not slow down your construction project.

Keep Sanitation Units On Site

As your employees work long hours, they are bound to need frequent restroom breaks. Disturbing neighboring businesses may bring more problems than collaboration. It’s not very productive for these restroom breaks either as they need to spend the time walking or driving off site. Instead, provide clean restroom facilities and portable sink options for employees to access easily in seconds.

Don’s Johns has many sanitary options available for your construction site. The above tips combined with portable restroom options are a sure way to increase production for your next project.

Keep Your Customers Happy, Even During Business Remodeling


Don’s Johns has been servicing the greater Washington, DC area for 50 years. As you may think of us as just a provider of portable restrooms for construction crews, concerts, weddings, and other special events, we also are here for our local businesses, even during remodeling.

If you’re working on a simple or complete remodeling project, you still have a business to run; you can’t just close your doors. Don’s Johns understands your pains of trying to keep happy customers, even during your business remodeling season. Here are three ways partnering with us helps you keep your customers happy during such a hectic and unorganized time.

Leaves the Impression Your Employees Practice Sanitary Habits

In most establishments, there are employee restrooms and separate customer restrooms. However, sometimes a place of business only has one. Your customers are going to notice the lack of restrooms for your staff, be it a food establishment or general retail store. Good hygiene and sanitary practices are expected nowadays. With germ spreading on the rise, a customer can’t help but notice and wonder if your employees are washing their hands throughout the day.

Help ease your customer’s mind and let them know that you have a clean restroom facility on site for your staff to use. This is also a great way to show the contractor and their crew you are looking out for their best interests as well. Don’s John’s restrooms each have hot and cold running water and ample amounts of soap. You’ll also find having a few hand sanitizers in your restaurant establishment for employees to use once they’ve left the restroom is comforting as well.

Don’t Lose Customers Because of a Lack of Restroom Facility

When your customers come out to shop and browse, they want to do so comfortably. However, having children with them could cut their trip short, if you are renovating the store and restroom area. Your customers may need to change their babies. Toddlers alert parents right then and there they have to use the restroom, not a moment sooner. Once your customer leaves your place of business, this opens the door for them to visit your competitor, with a clean restroom waiting for their use. The possibility of them walking back to pick up that item they were eyeing is drastically reduced.

Get the Portable Option to Meet the Needs of Your Customers

Make sure your customer needs are being met. Don’s Johns has a variety of standard portable restroom solutions as well as luxury restroom trailers that are ADA compliant. Each trailer is stocked with antibacterial soap to use with hot and cold running water, which is perfect to prevent the spread of germs during the cold season. The cool winter air prevents most from wanting to use a standard portable unit outdoors. However, our restroom trailers are a climate-controlled environment, for those side-walk sale shoppers to relieve themselves in comfort.

You can count on Don’s Johns to provide the portable restroom facilities your organization needs. We have plenty on hand and available for you to use for as long as you need.

How Many Porta Potties Are Needed For Special Events

porta-pottiesIf you are planning a special event, it’s hard enough trying to get an accurate count of guests to determine how much food and beverages you will serve. You must know how many chairs and tables to set up. Possibly even how many party favors to have as well. You also should be sure you have enough porta potties on site from Don’s Johns.

You see, hosting events, you can expect your guests to enjoy the food and beverages, especially if it’s a warm day. Participants are having fun and are more sociable while drinking. What agitates guests at events is being uncomfortable, too hot, babies may need changing, or guests needing to wait in long lines or walk uncomfortable distances to the restroom. Here are a few suggestions to having happy guests stay at your event.

How many Porta Potties?

Don’s Johns Tips to Consider:

  • As long as you are having a headcount of fewer than 50 people, 2 portable restrooms are a great start to accommodate your guests.
  • If you have a 4-hour event on a hot day, having 3 DJ4000 Restroom Trailers provides a great air-conditioned environment for 100-250 guests to cool off.
  • The longer the event and more attendees, you want to increase your numbers. This allows guests to continue to drink and have a good time knowing they have access to the restroom
  • Remember, if you have more than 50% of your participants as women, you need to increase the number of units by at least 25%.


Women tend to check their makeup and to refresh themselves in groups, so you need a place that’s roomy enough and accommodating. The DJ5000LX Luxury Presidential Restroom Trailer has beautiful granite countertop and is spacious. This well-lit mirrored area is stocked with plenty of paper towels and clean hot and cold water. Guests can talk about the night’s events and lounge around. They can keep up with what is going on outdoors via 3 flat screen televisions and listen on the dual audio system.

You can also consider the DJ2300LH Luxury Restroom Trailer w/ADA Room, as these units are ADA compliant of which you should have a good 10% of all portable restrooms as one to accommodate disabled or senior guests.

Remember to keep all parties involved, having portable handwashing stations around will be helpful. They don’t have to go into the restrooms to have clean hands and enjoy their foods. Parents can use the hand wipes to keep children’s faces and hands clean as well.

As a woman-owned business, Don’s Johns understand all these needs. Contact us today and an advisor can personally assist you with the number of clean uncomfortable portable restrooms to have at your indoor or outdoor event.

How to Choose The Right Porta Potty Rental

A porta potty rental is extremely important to have at any outdoor project or event.  A porta potty can be used at an outdoor concert, outdoor festival or for construction workers working outdoors or at your house for renovations. Don’s Johns has porta potties for each and every occasion. In fact, let us help you choose a porta potty for your upcoming event with these helpful porta potty rental tips.

Evaluate where your event is taking place

If you are having an event like a food festival or an outdoor health care fair you want a porta potty rental that does not just have a toilet, it also needs a sink. Portable bathrooms such as the VIP Flushing toilet With Sink is great for allowing people to use the bathroom comfortably and clean their hands appropriately.

Festivals also draw many different crowds of people; having a toilet that caters to all different types of people is very important. The Wheelchair Access Portable Toilet has plenty of space and is great to rent with another porta potty rental so that everyone can use the bathroom comfortably.

luxury-porta-potty-rentalEvaluate who is coming to your event

You can choose what portable bathroom to rent by evaluating who exactly will be attending your event. If you are looking for a porta potty rental for a special event such as a celebrity gathering or government inauguration, you are going to want to rent our Luxury Presidental Restroom Trailer. This station has luxurious sinks, toilets and fixtures that will impress those of importance.

Does your event evolve around children or babies? Then you should choose to rent our Baby Changing Stations. These stations are great for mothers to be able to change their toddlers and babies. There is no toilet in the room so you have plenty of space to change your child quickly and comfortably.

Portable Toilets to Office Trailer Systems from Don’s Johns

Not having fresh water systems on site can be a nuisance. You feel as though you are required to provide bottled water for employees on hot days inside. You also may want to avoid a standard portable toilet inside your office. If you require temporary restroom’s inside your office trailer with flushing toilets, Don’s Johns has your complete office trailer systems ready to deliver. You don’t even have to have access to a sewer or septic.

Complete Office Trailer Systems

If you do not have a sewer or septic hookup, our standard office trailer systems comes equipped with a 100 gallon fresh water holding tank and 250 gallon secured waste container. We even offer a fresh water toilet if you don’t have one. The best part is the interior office trailer system can be setup totally from the outside. You won’t know we are there servicing you.

Office Trailer Systems – Additional Components

If you will be using more than the provided fresh water holding tank or secured waste container that’s not a problem. Don’s Johns systems are set up to hook an additional tank and container up for maximum usage. You can reduce the number of service calls we make.

We are concerned and want to make sure we are affordable for all our clients. That’s why we offer the Lo-Fl toilet as well. This toilet reserves the water, similar to which an airplane toilet does.

Portable Sink Option

Since your site does not offer fresh running water we are able to offer you a hot and cold portable sink. This sink is designed to provide you with fresh drinking water as well as cleaning your hands. You have an attached paper towel dispenser that will never disappear on you.

3 Factors in Properly Planning Your Porta Potty Rentals

One thing that everyone has in common is the need to use the restroom.  In public, those restrooms are going to most likely be portable restroom rentals.  Regardless of what industry you’re in, it’s important to think about who’s going to be at your site and for how long.  Construction workers pull long shifts, where a portable toilet rental is essential.  Event attendees may be at a concert, fair, festival or barbeque for six to eight hours.  Outdoor weddings and receptions have hundreds of guests, all looking for a place to use the loo.  If you’re the operations manager or site supervisor for one of the preceding functions, here are 3 factors contributing to why proper porta potty rental planning is so important.

Properly serving Attendees at your location:

The importance of how many people will be at your location is paramount.  You don’t want to have lines that are 25 feet long, but at the same time you don’t want 15 extra portable restrooms sitting unused.  Keep these tips in mind –

If you’re in construction, consider a porta potty for every 7-10 workers on site. Are you working on multiple stories?   A hook construction portable toilet rental is the perfect addition to prevent downtime and long lines.  Are you working from different locations, staying mobile as you move from site to site?  Think about the importance of renting a Porta Potty with an included Trailer for your road crew.  If you’re working in an office trailer, interior restroom systems make it convenient for you so that you don’t even have to leave the office! porta potty rental, portable toilet rental, portable restroom rental, porta john rental

If you’re an event planner, don’t just think about how many people are going to be at your event.  The first thing we want to know is if you are you serving alcohol at your location. If you are, automatically increase the number of portable restroom units by 20%.

Here’s our second question – Do you think that women will create above 50% of your audience demographic? If so, increase your number by 25-50%. Also, make sure 10% of your total numbers of portable restrooms are handicapped units to follow ADA compliance at your location.  If you’re conducting an event where individuals in wheelchairs will be more prominent, our experts will help you adjust accordingly.

Length of use:

Are you tirelessly trying to figure out the algorithm that tells you how many porta potty rentals you need for a certain amount of people and time?  Forget about the hard work; We’re the experts, leave the portable toilet troubles to us and just follow our easy chart when planning your portable restroom rental needs.

 Proper Placement

If there is one key to a good portable restroom rental company, it’s the service. To help you have your best experience, we suggest that your portable toilet or restroom trailer always be placed within 15 feet of a hard surface to ensure that our service trucks can access them without difficulty. In addition, our account managers can help guarantee the least interruption by scheduling and providing service before your site opens in the morning, or after it closes at night.

Don’s Johns has the largest selection of portable restrooms in the Washington D.C., Maryland, and Virginia area to meet your needs. Whether it is a standard portable restroom rental, VIP flushing toilet, or Luxury Premier solar powered restroom, we have the products to fit any size need and budget.

Portable Sanitation – Associating Internationally!

With a constant need for Porta Potty rentals placed at multiple events and projects around the globe, our industry is continually expanding.  One can often wonder where the Jacks and Jills of the John gather for information and updates in the Portable Sanitation community.  In 1970, a group of business leaders in the portable sanitation industry met in Don’s Johns hometown, Washington, D.C. to discuss portable restrooms and sanitation standards. The rest was history – and PSAI was born.

The Portable Sanitation Association International (PSAI) looks to be recognized as the authority within our industry.  PSAI represents members around the globe through regional networks to maintain and constantly improve upon the standard for all companies providing portable toilets, restroom trailer rentals and other portable sanitation services, making the environment a cleaner, safer place for everyone.

PSAI focuses on the multiple advantages portable sanitation brings to a situation.  According to the PSAI website, there are multiple cost saving, health and environmental reasons to rent portable restrooms, a restroom trailer or other sanitation facilities for permanent and temporary locations.  Portable Restroom Rentals serve many different functions, such as:

  • Special Events
  • Construction
  • Parks
  • Government Agencies
  • Sporting Events
  • Public Gatherings
  • Disaster Relief, and other outdoor needs.

Since their official founding in 1971, PSAI has evolved into a global resource for portable restroom operators and associates alike.  An official certification program has been implemented to maintain high standards in portable sanitation, as well as round table and panel discussions with experts sharing information and solving problems within the industry.

Industry conferences are also held, including the 2011 PSAI convention recently held in San Antonio, TX.  Attended by top industry experts, as well as some of Don’s Johns finest, awards are distributed to those who are innovating and staying dedicated to providing the best in portable restroom rentals and sanitation services.  PSAI also promotes expanding education within the porta potty business by offering scholarships to up and coming employees within the industry.
