Therma Tru

Therma Tru

It was a bold innovation for the home-building market 25 years ago when they introduced an entryway door that looked as beautiful as wood but performed with the durability of steel. But revolutionizing the industry is what you can expect from the nation’s leading manufacturer and most preferred brand of fiberglass and steel exterior door systems.

TESTIMONIALS

Laura N. of Silver Spring, Montgomery County, MD 20906

(Found on CheckBook.org) After researching front entry doors, we decided to replace our front entry door with a ProVia door (which included a whole new frame with sidelights, hinges, door knobs, etc.). We decided on ProVia because we wanted a high quality, energy efficient, functional door system that would not need repairs or replacement a decade from now. After receiving a couple of quotes from other highly-rated installers, we had Crystal Exteriors come to our home to take measurements. We decided on Crystal Exteriors because in addition to giving us a good price, the owner, Mr. Edgar Li, impressed us as being experienced, informative and professional. There were no games or gimmicks, he was very straightforward in terms of price and information.  The installation exceeded our expectations as well. Mr. Li does not subcontract, his crew is very efficient and skilled and they have worked with him for years. It is clear that Mr. Jaime and another crew member take pride in their workmanship. They took great care to isolate the area around the door with a floor to ceiling plastic drape and worked with great care and respect for our property. Years ago, I used another highly-rated firm to replace our sliders, and while their crew did a good job, they did not isolate the area the way the Crystal Exteriors crew did. Mr. Jaime and his crew go the extra mile. Not only did they replace the visible wood rot around the door, they also replaced hidden rot that they found in the subfloor. They did all of this additional work with absolute thoroughness and for a surprisingly low minimal cost.  To say that we are happy with their work is an understatement. We are beyond pleased with the quality of our door as well as the outstanding experience we had with the installation. In addition, we noticed immediately how much more energy efficient the ProVia door is and that alone definitely makes the upgrade worth every cent. Crystal Exteriors also replaced two windows with ProVia windows and they are extremely energy efficient compared to our original windows.
