Our History

Maintenance Unlimited is a family business, through and through. Founded in 1977 by Ben and Linda Nathan, it is currently run by their son Gabriel Nathan. Gabriel’s own sons—Jacob and Joshua—are also an integral part of the company. In time, they will be the third generation of the Nathan Family to lead Maintenance Unlimited towards the future. 

With over 45 years of experience successfully operating in the El Paso area, Maintenance Unlimited has continued to adapt itself to changes in the market by adopting emerging technology and incorporating other best practices in order to stay on the cutting edge and continue to deliver the best value to our customers. 

We have grown considerably, greatly expanded the services we offer, built a loyal customer base, established a reputation as being the local cleaning company of choice, and defined ourselves as the market leader.

How We Build Our Team

Following our initial application and hiring process, each employee is thoroughly trained. Employees always work in teams, allowing for both cross-training and ongoing accountability and integrity. Our cleaning staff is fully uniformed and wears a Maintenance Unlimited work smock for a clean appearance that identifies our employees while complementing your professional work environment. Should a customer require employee badges or any additional employee screening, we are happy to accommodate those specific requests as well. 

Maintenance Unlimited pays all employees above the minimum wage, with periodic reviews and merit increases, paid vacations and holidays, as well as holiday bonuses. We have been able to maintain a very good employee retention rate, with several employees being employed by the company for more than a decade. That directly translates to a more experienced, capable, and efficient workforce for our customers.

Our Quality: Continuously Striving to Exceed Expectations

Being locally owned and operated, we are able to maintain excellent control over the quality of our service. Maintenance Unlimited takes extreme pride in our unsurpassed quality and believes that cannot be replicated in the same way by a company offering service in El Paso, but based elsewhere. 

Being on-site is an important part of Maintenance Unlimited’s inspection process. We are able to personally cater to our customers and routinely inspect our buildings and monitor the performance of our employees. 

  • Our account managers physically spend time at each of their accounts on a very regular basis. 
  • We meet frequently with customers, allowing for open dialogue regarding any quality concerns. 
  • By using smartphones and tablets, account managers complete a routine checklist specific to each account. 
  • We generate inspection reports from the data collected during our inspections, providing information about the effectiveness of the cleaning crew’s work and identifying opportunities that may exist for improvement.
  • Quality control is maintained by our tiered management approach. 
  • Cleaning crews are led by an on-site supervisor and overseen by an account manager who reports to the owner. 
  • No crew is left without checks and balances.
  • The arrival of staff is monitored each day and we ensure they always work the designated number of hours. 
  • Our staff is always able to access a supervisor or member of management to answer any questions they may have or to support them in any way. Each employee is thereby closely managed and accountable.

A Closer Look at How We Run Our Business

Several elements of our business protocol also guarantee that we continue to deliver top-quality service. We attend the BSCAI’s (Building Service Contractors Association International) Annual Convention to stay abreast of best practices and to learn about new products and equipment on the market. 

Maintenance Unlimited invests in high-end, up-to-date, specialty equipment. Every machine we use has been specifically designed for the application in which it is being used. This allows us to consistently provide our customers with the highest quality work and most professional results possible.


Maintenance Unlimited carries general liability insurance in the amount of $1,000,000 and worker’s compensation insurance in the amount of $1,000,000 per occurrence, and an excess umbrella of $3,000,000, for an aggregate of $2,000,000 in coverage.


Bonding is so important because it provides a level of assurance and protection to your businesses and your customers. Our employees are bonded in the amount of $25,000.


We will be pleased to provide letters of recommendation from several of our customers upon request. We are also happy to have prospective customers accompany us on a tour of a building we already clean so they can assess the quality of the service we provide first hand.

Letters of Recommendation

We have received numerous letters of commendation from our customers regarding the work of specific employees:

This letter is to inform your company about the work of Maria.  I am a tenured employee and have been with the agency for over nine years. I have never seen our offices look so clean and orderly as I have since Maria has been on staff.  She is very efficient in her work. She goes out of her way to make sure the entire building is super clean.  The bathrooms are always in order, our break room is always clean and the whole office in general is, without a doubt, sparkling.  I would just like to comment on the great work Maria is doing for our office as we always hear the negative things but never the good.  I am glad she is on our team!

-Maria has worked for Maintenance Unlimited since March 1996.

Yesterday afternoon I lost two rings, not very expensive but dear to my heart.  I mentioned what happened to the evening custodian and asked her if she would look out for my rings and if by chance she came across them to please turn them into the security office.  This morning it was to my pleasant surprise that my rings had been found and returned.  All too often when things go missing the custodians are the first ones to be blamed.  This time, I want to be the first to thank the custodial staff, especially the employee who returned my rings, for her initiative, good work ethic, and honesty.  Thank you!

It gives great pleasure to write this letter in reference to your fine employee, Bertha.  I wish to express our sincere appreciation for the excellent services provided by her.  Her professional competence, courtesy, and thoroughness in performing her duties are greatly appreciated by our staff. Thank you so much for your outstanding organization and please convey our sincere thanks to Bertha.

-Bertha has worked for Maintenance Unlimited since June 2000.

Please tell your cleaning crew “thank you very much” for being so honest.  Apparently, one of our employees had lost $60.00 in cash which he hadn’t even noticed and the next day he found an envelope on his desk with the cash inside with a note stating that the money was found on the floor under his desk. Please thank your crew for us and tell them we appreciate their honesty.

I want to let you know that I have been very impressed with the job that Jorge, the day porter has been doing each day. I run into him frequently and am very impressed with how much time and effort he puts into his cleaning duties. When he cleans the restrooms, they are CLEAN! He is very meticulous and thorough. I have told him that I think he does a great job and I want you to know as well.

-Jorge has worked for Maintenance Unlimited since October 2008.

I wanted to write you and let you know that one of our employees in HR lost her bracelet yesterday. I would like to commend your staff. They found the bracelet and put it back on her desk. She was ecstatic this morning when she saw the bracelet on her desk. I want you to know that we appreciate the professionalism and honesty your employees have shown.
