Cleaning: “It’s what we do!”

Our company’s foundation is built upon our Christian faith; we are hardworking, dedicated, professional, reliable, loyal, honest and kind. Our passion for what we do is what separates us from others, and our commitment to excellence and our high standards are second to none!

Definition of Cleaning — Institute of Inspection Cleaning and Restoration Certification (IICRC) S100-02

Cleaning is the traditional activity of removing contaminants, pollutants and undesired substances from an environment or surface to reduce damage or harm to human health or valuable materials. Cleaning is the process of locating, identifying, containing, removing and properly disposing of unwanted substances from an environment or material.

Every time that we enter your establishment, fulfilling this definition of cleaning is our commitment to you. It is of the utmost importance to Cornerstone Cleaning Services to not only give the appearance of clean but to Actually clean! It is not of our nature or our mindset to rush through your space to get to the next job. We methodically take the time, effort and pay attention to the smallest detail to clean to your satisfaction. We are often our worst critics and treat your property as if it were our own. It is about pride in our work and the satisfaction of a job well done that keeps us motivated to achieve the highest standards possible.

Our objective is to become the industry standard

We will achieve this goal by:

Listening attentively to your needs.

Continue to research and learn in order to remain experts on the latest cleaning products, equipment, and practices.

Our cleaning must meet or exceed client’s expectations to be considered done. “We give you a rock-solid guarantee—Immaculately clean or we fix it for free!”

The stone that the builders rejected has become the cornerstone;
the Lord has done this and it is marvelous in our eyes.

Psalm 118:22-23
