Yes, you can finance new windows with us. We offer 0% for 18 months* through Synchrony, with payments as low as $87/month* for a house full of windows. You apply during your free in-home quote and get an answer in minutes.
This guide covers how that works, what promotional financing means in general, and the questions worth asking before you sign anything. *Rates and terms dependent on qualifying credit.
How Financing Works With Us
- We measure and quote first. Our own crew measures every opening, and you get a written price before financing comes up.
- You apply during the visit, if you want to. The Synchrony application happens during the free in-home quote, and you get an answer in minutes.
- You read the terms. The promotional terms come from Synchrony and depend on qualifying credit. We do not set them, and we will not guess at them.
- We install. Our own local crew installs every window, and each one carries our transferable Lifetime Warranty.
What we can tell you is the advertised offer above. What decides the rest is Synchrony’s written terms, based on your credit. We would rather you read them at the table than hear a promise from us that the paperwork does not back up.
Financing is an option, never a requirement. More detail lives on our replacement window financing page.
Not Every 0% Offer Works The Same Way
Promotional financing is a broad label. Synchrony describes several kinds of promotions, and the differences matter most when a balance is left at the end.
| Promotion Type | How Interest Works | What To Watch |
|---|---|---|
| Deferred interest (no interest if paid in full) | Interest accrues from the purchase date but is charged only if the promotional balance is not paid in full in time | A leftover balance brings back interest on the full purchase price, back to the purchase date |
| No interest (0% APR) | No interest accrues during the promotion | After it ends, interest applies to the remaining balance going forward |
| Equal payment, no interest | 0% APR, with the same payment every month of the promotion | A predictable bill; make sure the payment fits your budget |
| Reduced APR, fixed payment | Interest accrues at a reduced promotional rate | You pay some interest, so compare the total cost |
The CFPB says one word is the tell, and the word is “if”. When an offer promises no interest if paid in full by a date, it is a deferred interest offer. Synchrony makes the same point: if the promotional purchase is not paid in full in time, accrued interest is charged.
Our offer is advertised as 0% for 18 months. When you apply, ask which of these types your approved terms are, and read the answer in Synchrony’s written terms.
Questions To Ask Before You Sign
- Which kind of promotion is this? Deferred interest and a true 0% offer behave very differently at the end.
- What is the exact end date? The CFPB says to know it, and notes that for deferred interest it appears on the front of your bill.
- Will the minimum payment clear the balance in time? Both Synchrony and the CFPB warn that minimum payments may not pay off a promotional balance before it ends.
- How are extra payments applied? The CFPB says extra payments usually go to your highest-rate balance first. In the last two billing cycles of a deferred interest period, they must go to the deferred balance.
- What if a payment is late? On a deferred interest plan, the CFPB says being more than 60 days late can cost you the promotion.
- What rate applies after the promotion? That rate is in your credit terms. Get it in writing before you sign.
The CFPB also suggests paying off the balance well before the end date, so a slow payment cannot trip you up. That is good advice for any promotion.
A simple plan keeps it on track:
- Set your monthly payment to the balance divided by the months in the promotion, not to the minimum.
- Never miss a due date, since the CFPB lists that among its core tips.
- If you carry other balances on the same account, ask the issuer to apply extra payments to the promotional balance, as the CFPB suggests.
- Put a reminder on your calendar a couple of months before the end date, and keep your statements.
Fitting A House Of Windows Into A Monthly Budget
With us, a typical 10-window home runs roughly $5,450 to $6,990, depending on the model. That is the range for white double hungs with basic installation; grids and colors add to it.
The budget math takes three steps:
- Start from the written total. Use the number on your quote, not a starting price, because your options are in it.
- Divide it by 18. That is the monthly payment that clears the balance inside an 18-month promotion.
- Compare it with your budget. If that payment fits comfortably every month, financing can work for you.
The model you pick moves the total. Per window, the ladder starts with the Harvey Slimline at $545 and the Gentek Series 3000 at $587. The Harvey Classic sits at $617. The Harvey Tribute and Gentek Series 9000 are $683. The Harvey Homerun is $699.
Our prices include basic installation, so you are dividing an installed price, not a window price with labor still to come.
Do the same check on any payment you are quoted: multiply it by 18. If the result is less than your balance, that payment alone will not clear it inside the promotion.
If the payoff payment feels tight, there are honest ways to shrink it. Choose a lower rung, like the Harvey Slimline at $545 instead of the Homerun at $699. Or replace the worst windows now and the rest later. Our guides to Massachusetts window costs and New Hampshire window costs lay out every model.
When Financing Makes Sense, And When It Does Not
Financing fits best when you can pay the balance off inside the promotion and would rather keep cash on hand. It fits less well when the payoff payment would strain your budget every month. That matters most on a deferred interest plan, where a missed deadline brings back interest from the purchase date.
If you are not sure the windows need replacing yet, read our guide to the signs you need new windows. Also check window rebates and tax credits in NH and MA before you settle on a budget.
Frequently Asked Questions
Can I apply for window financing during the quote?
Yes. You can apply during the free in-home quote and get an answer in minutes. Rates and terms depend on qualifying credit.
Is 0% for 18 months the same as deferred interest?
Not necessarily. Some promotions charge no interest during the period. Deferred interest promotions charge accrued interest if the balance is not paid in full in time, so ask which type your terms are.
What happens if I do not pay it off in 18 months?
That depends on the promotion type in your terms. With deferred interest, the CFPB says interest is charged back to the original purchase date. With a true 0% offer, interest applies to the remaining balance going forward.
How much should I pay each month?
To clear a balance inside 18 months, divide it by 18. A 10-window home at our starting prices runs roughly $5,450 to $6,990 before options, so start from your own written quote.
Does applying for financing affect my credit?
The CFPB says a lender’s credit inquiry typically has a small negative effect on your credit scores. Ask at the quote what kind of credit check the application uses.
The simplest way to see your real numbers is a free in-home quote. We measure, put the price in writing, and you can apply for financing on the spot if you choose. There is no pressure either way. Call (603) 764-7212, Monday to Friday 8:00 to 5:00, or use the form below.
