The Patent
This patent provides a method of repairing or patching a defect in a vinyl window frame with a PVC adhesive or filler, including a PVC cement. Using products not manufacturered by Vinyl Doctor, or not licensed through Vinyl Doctor, to repair vinyl window frames can violate US patent laws.

Repair technicians, who adhere to the VinylDoc method and exclusively use VinylDoc products, are granted limited rights under US Patent law for the use of the patented method. In so doing, their repairs can meet industry certification standards.

Beware! Imitators use substandard products and methods. Use of bondo, fiberglass, epoxy, paint and PVC cements not unauthorized by VinylDoc are substandard repairs and are illegal. Inevitably, substandard and illegal repairs bring financial liability. Professional reputations and customer goodwill is at stake and may be irretrievably damaged.

Be safe, use "Liquid PVC" from VinylDoc.
"Testimonials"
"Your VinylDoc process saved the project a tremendous amount of time and money ... All of the repairs, including the inlays, are invisible now that the buildings are complete. On top of this, we were always able to facilitate repair of the windows from the outside of the building thus greatly reducing the impact of the construction process on the residents... The 2000 plus residents spread across the 640 units here unknowingly thank you for this...In the future, I would not hesitate to recommend VinylDoc for any type of vinyl framing repairs"…

" I have reviewed the 'Repair to Vinyl Windows using The VinylDoc repair program'. The method of repair and the material used will not void our warranty of the window. This is not a statement that we will warranty the repair work."
- Quote from a Window Company,
Director of Engineering,
regarding a Central California Project



" We had a situation in which over 240 vinyl windows in almost 75 occupied homes needed extensive repair to an otherwise inaccessible area of the window's wet chambers. The work was rigorous, requiring a painstaking and highly technical detection and repair process. During the execution of this arduous work, there was not a single incident of unhappy or dissatisfied homeowners. VinylDoc crews were clean, accurate and professional. Given the alternative repair protocol of complete removal and replacement of stucco-finish homes, they were also a very economic option…………. The patented liquid PVC material itself, which is used exclusively in almost all of the major window manufacturers' plants and as many of their only endorsed repair material, was never in question----even before we had it meticulously accelerated age tested at an AAMA laboratory, which it passed with flying colors. As far as the aesthetic quality of the finished product goes, we had a fenestration expert, who has been in the business for over 20 years, go into a home and try to find which 6 of the home's 25 windows had been repaired. To his amazement, he was unable to tell which ones they were. This is a remarkable thing, considering the extent of repairs that were done to these 6 windows. And beyond all this, the structural integrity of the repaired windows is as good, if not better, than brand new product. Again, I highly recommend VinylDoc for any vinyl repair, no matter how large or how small."

"About Us"
David Fenske started as a warranty manager for a major contracting firm in Portland, Oregon. He observed that water infiltration from improper handling of vinyl windows created problems and consumer discontent. His solution was a repair method that would satisfy all parties, not deteriorate like existing window frame repairs and meet the certification standards of the manufacturer. The business quickly grew and his brother Dale joined him.

David then patented his method. Window manufacturers noticed the improved customer satisfaction and started asking about his products. Vinyl Doctor, the window frame specialists, was born.

More than 10 years of quality service window manufacturers gained appreciation from the window industry for our cost effective solutions. Because of the superiority of our methods, both contractors and window manufacturers recommend the VinylDoc repair system.
