Per month
0% interest · nothing extra
One price, financed or cash — financing never raises it, and paying in full earns a discount. Estimates are for planning only; your exact price comes after a free measure. Actual terms depend on approval and the program available when you apply. Programs are provided by Service Finance Company, LLC and can change without notice.

Worth knowing
It pays you back.
Windows and doors are not like most things you spend money on around the house — this is an investment that shows up in three places.
Of your heating and cooling goes out the windows.
That is the Department of Energy estimate for what old glass costs a house — a bill you pay every month for windows that stopped working.

ENERGY STAR puts the savings at $101–$583 a year when certified windows replace single-pane windows — money that shows up every season, for as long as you own the house.

We get to work
Your first payment is not due until the job is done. Then it is one fixed amount a month.
Financing is not free money, and I am not going to pretend it is. But here is the thing about windows and doors — they are one of the few purchases that pay you back twice. Your heating bill drops the first winter, and the value shows up again the day you sell. So if the 0% program fits your project, take it: the house starts paying you back while you are still paying it off. And if nothing here fits, I will tell you that too.

Straight answers
The things people actually ask us on the phone.
Will applying hurt my credit?
Service Finance runs a credit check as part of the application. Ask us before you apply and we will walk you through exactly what to expect — we would rather you know up front than be surprised.
What credit score do I need?
It depends on the program. One of the shorter-term options lists a reference score of 580, while other programs have their own requirements. There is a range, so do not count yourself out before asking.
How much can I finance?
Depending on the program, from as little as $500 up to $100,000. Most window and door projects land comfortably in the middle.
Is 0% interest real, or is there a catch?
It is real on the equal-payment programs. The catch on same-as-cash programs is different: you have to pay the balance inside the promotional period, or interest can be applied. We will always tell you which type you are signing.
When is my first payment due?
Not before the work is complete. You are never paying for a project that has not been finished.
Is the number on this page what I will actually pay?
No — it is a planning estimate. It divides your project amount across the term you picked, which is what a 0% equal-payment program does. Your real number depends on the final quote, the program you are approved for, and what is available the day you apply.
Are these rates guaranteed?
No — and any company that tells you otherwise is not being straight with you. Programs, rates, and terms come from Service Finance and can change without notice. We confirm what is actually available the day you apply.
