Tod Williams Billie Tsien Architects LLP
New York and Philadelphia

Guaranteed On Site has worked with our design firm on two high-end, public projects that involved the use of artistic fabric wall panels. Guaranteed On-Site explained the process and options available to us in a professional and careful manner. Their testing was done on time and successfully enabled our design to use the large scale tapestries to animate and acoustically dampen the public gathering spaces. Their final application was perfectly done without impacting the color or texture of the fabric and was delivered on time; even after our construction schedule reduced the amount duration they had to treat the materials. Our firm unequivocally recommends Guaranteed On-Site.

Gene & Mike,

It was a pleasure having Guaranteed On Site come to clean and fire proof all six schools stage curtains. Your crew was very professional, prepared and ready to work. You were able to work with us on such a short time span to turn this around. (You made me look good). A great big thank you to your crew. I would highly recommend your company.

Newton School District
Newton, NJ

Dear Hill,

I want to thank you for the fine job your crew performed cleaning and treating our stage curtains with a flame retardant chemical. The curtains look brand new at all three schools. After reading the article in School Planning & Managemant, Safety & Security section, about the fire danger involving stage curtains, you called at the perfect time. You gave me the date you were coming to perform your services and arrived on time. I was very pleased as this isn't always the case with other companies these days. You cleaned up and left the school in better shape then when you arrived. Thank you and hope to see you in another five years.

"To whom it may concern,
We were lucky, we were picked by the State Fire Marshal to have a full inspection and it was found that our stage curtain was not up to code and we needed to have it made fire retardant. I received a recommendation about your company and they were on target.
In this day and age of busy schedules, your compnay kept their appointment for the estimate and your schedule to perform the work itself. Something that is so rare. The workers were extremely courtous as well as neat with the work and explained the process and what to do afterwards all this for a very resonalbe cost. I would highly recommend your company to anyone needing the same serivce.
You may pass along my information should anyone want to contact me regarding your company".

It was a pleasure to have Guaranteed On Site here at the
Majestic to clean and fireproof our stage drapes. Mike and his crew were professional, courteous, and friendly. The pricing was very reasonable and the cleaning and application took no time at all. We know that our stage drapes are ready for another five years of shows, at which time we will have Guaranteed On Site back to take care of them again.

You and your staff could not have been more courteous and accommodating in meeting our needs.

The crew that came out completed their work in the estimated time and left the area as neat and clean as when they arrived. It was a pleasure working with your company!

Dear Gene:

I would like to thank you and your staff for your cooperation and quick response to our needs as a result of a fire inspection, which resulted in our receiving a violation for not having a certification of flame retardant to all our window dressings.

I have to praise you and your company for being sensitive to my needs and responding quickly and professionally. From the time i contacted your firm to obtain a proposal to correct the violation, to the completion of the job, i can say without a doubt, it was a most favorable experience. You and your staff were courteous, professional and respectful of our furnishings.

I would not hesitate to acknowledge and recommend your company on the excellent manner in which you handled my situation and look forward to using your services again in the future.

Once again, I thank you for your prompt service.

Hi Hill,
A quick message to say thanks for the great job your folks from Guaranteed On Site did in restoring our soft goods back up to fire regulation standards last week.
The crew arrived on time, worked efficiently (and rather noislessly) for 5 hours and left the Schmidtchen Theatre immaculate after.
Their care in prepping the space was much appreciated, and their attention to detail in the application process is worth mentioning too;the crew that came south was topnotch.
Guaranteed On Site's product,service and crew was exemplary.
Well done,man;take a bow.

Dear Gene and Mike-

I just wanted to thank you both for all the work you did for us on our project. The services you provided, including flameproofing of principal and stunt costumes, as well as quick turnaround dry cleaning, were an integral part of our shooting schedule in Philadelphia. In spite of the constant challenges we presented you, you always came through- and with flying colors. We were impressed with both your professionalism, and your constant enthusiam to help. Again, I cannot thank you enough for all of your hard work. I would highly recommend your services to any project, and will be passing your name on to other films that make their way to Philadelphia. If you ever expand your business to Los Angeles, I will be your biggest fan….

"First let me thank you for your immediate response to our request to the cleaning of stage curtains at the high school, middle school auditoriums and curtains at two of our elementary schools libraries. I found your pricing to be lower than others who quoted the same work. Secondly, the quality of work was exceptional. I believe your people did a thorough job and we are pleased with the outcome. Obviously this is a reflection of the dedication you and your people have for the work you do".
