The Recovery Through Retrofit report (CEQ 2009)—a product of the White House Council on Environmental Quality, 11 federal departments and agencies, and six White House offices— identified property-assessed clean energy (PACE) financing programs as a means of removing barriers to expansions in the residential energy efficiency and retrofit market. Under PACE programs, municipalities and counties form special tax districts to help property owners finance energy retrofits by allowing a property owner to place an additional tax assessment on his or her property. Property owners who invest in energy efficiency (EE) measures and small renewable energy (RE) systems repay these assessments over 15 to 20 years via additional annual payments on their property tax bills. Please check out these provider websites to see if your home qualifies.

Gary Collins

For most of the 1990s Gary worked as a remodeling contractor. Then Gary learned of Weathershield windows and decided that maybe selling was better than buying.  He became one of the first Weathershield dealers in Northern California.

In 2005, he decided to quit dabbling and dedicated himself to offering and installing windows and doors,  by opening Windows & Beyond.  With his vast experience and network, Gary has been able to provide his clients with more than just the windows for their remodeling projects; Gary is able to refer other suppliers, contractors, and designers as well as act as a single point of contact – taking a great deal of burden away from clients.

Outside of the office, Gary is an extremely proud parent and grandparent. He also enjoys contributing to his community through Rotary, as the district chair for their leadership program for High School students, Camp Royal. In his spare time he also enjoys cycling and skiing.

Gracie Collins, Mascot

When in the office, Gracie acts as greeter, nurturer, and comic relief for everyone who enters. As a pug/beagle mix, she is very suited to her position.
A word of advice though, don’t come between her and her blanket!

"I have known Gary Collins of Windows & Beyond for more than three years.  I hired them to build a handicapped  bathroom and make other adjustments to our house so that  my husband, who had suffered a serious stroke, could return home.  They work was very fine and on Budget.  They are always on time, or if delayed for any reason, let us know promptly.   I am very happy to recommend their company to anyone who needs construction or repair work done to their home."

It was a pleasure having Windows & Beyond install my home's windows and doors.  They were professional and demonstrated a thorough understanding of the efficiency in the order of doing the work as only those who have had years of experience would know.  Their attention to every detail made for a very well-finished final result.   All in all, I cannot think of a thing that they could have done better!  I would highly recommend Windows and Beyond to anyone considering upgrading their home."
