You could pay cash, credit card, or through special financing. We have several options but the best bang for your buck would be the REELS program through Go Green Funding. You get 100% financing for your full window order with no payments for up to 24 months and it has a 5.99 APR which is very low compared to other places. We also have other programs like PACE, via the U.S. Department of Energy and Service Finances, which offers instant approval with no credit score required. All of these programs are different in their way, it all depends on which one suits you and your budget. If you want to know more information, just call us and we’ll be happy to help.
