How to Pay for New Windows in Colorado

By Fort Comfort Windows · September 2026

Most window companies have one financing answer, because they have one lender relationship, and the conversation about paying for the job is really a conversation about getting you into that product.

There are three realistic paths for a Colorado homeowner: pay for it, use one of two Colorado energy programs, or use contractor financing. We offer contractor financing through Enhancify, and we're an authorized contractor for both the Colorado RENU Loan and ClearPath On-Bill, so we have a horse in this race. The honest answer is that the right path depends on your situation.

Here they are, including the parts that are inconvenient for us to mention.

We're an authorized contractor for both RENU and ClearPath. The financing page has the short version and how to start an application; this guide is the honest long version.

Get a real price first, then talk financing.

We give you a written, line-itemized quote and walk you through every path you're eligible for, including the ones that are inconvenient for us to mention.

Path 1: Pay for it

Obvious, and worth stating, because financing gets pushed hard in this industry and the reason isn't always your benefit.

If you have the cash and no better use for it, paying outright is the cheapest version of the project. No arrangement beats not paying interest. Anyone who tells you otherwise is selling the arrangement.

Where this gets interesting is phasing. Window work doesn't have to happen all at once. Plenty of homeowners do the worst elevation this year and the rest in two years, and pay cash both times. We'll help you decide which windows are actually worst — that assessment is free, and it frequently means a smaller job now than the one you called about.

Path 2: The Colorado programs, RENU and ClearPath On-Bill

The Collective Clean Energy Fund, Colorado's nonprofit green bank, runs two programs that cover windows, and we're an authorized contractor for both.

The Colorado RENU Loan is a program loan through participating Colorado credit unions. Its scope is broader than windows alone: doors, storm windows and doors, air sealing, and insulation can go in the same package. As published by CCEF, funding is available up to $75,000, there are no prepayment penalties, and the loan is secured by a UCC-1 filing on the installed measures only, with no lien on your property. You pick your lender from the participating credit unions. Rates and terms come from the program and its lenders, and CCEF publishes them directly.

ClearPath On-Bill is the genuinely unusual one, so the rest of this section covers it in detail.

ClearPath On-Bill is administered by the Collective Clean Energy Fund, Colorado's nonprofit green bank, and it lets Xcel Energy customers pay for eligible home energy upgrades through a line item on the utility bill they already receive. There's no separate loan account and no separate payment. Windows and doors are on the eligible measures list.

The terms, in full

CCEF publishes these on their own site. We're reproducing them together rather than picking out the flattering ones:

Rates and terms are published by the Collective Clean Energy Fund and are subject to change. Confirm current terms at cocleanenergyfund.com. Fort Comfort Windows is an authorized contractor in the program. We are not the lender and we do not set the terms.

Who qualifies

Underwriting is deliberately different from a conventional lender. Instead of leaning on your credit score, the program looks at your utility payment history:

For a homeowner with thin or damaged credit and a clean utility record, this is a meaningfully easier door to walk through than a conventional loan. That's the design intent of the program.

The part that's genuinely good

You own the windows from the day they go in. CCEF covers the upfront cost and you repay through the utility bill over time, but the improvement is yours immediately.

The part nobody mentions

If you sell before the balance is paid off, the repayment obligation stays with the electric meter, not with you. The new homeowner assumes it when electric service transfers.

That sounds like a feature, and in some situations it is. But it comes with an obligation: you're required to disclose it to potential buyers. Some homeowners choose to pay the balance off before listing simply to keep the transaction clean.

That's not a reason to avoid the program. It's a reason to know about it before you sign rather than during a closing.

One more: because the charge rides on your utility bill, it's subject to the same collection treatment as the rest of that bill. A missed payment is a utility problem, not just a lender problem.

Path 3: Contractor financing and conventional loans

Contractor financing through Enhancify and its lending partners, or a loan you arrange yourself: a home equity line, a personal loan, or a credit union home improvement loan.

Contractor financing is the fastest option and the one most homeowners use. You can check your options on our financing page, and checking does not require a hard credit pull; a full application may. All rate, term, and payment information comes from Enhancify and its lending partners, with their disclosures. We do not set those terms. Either way, you get the project price in writing first, so you can compare any financing against it.

Where conventional financing genuinely wins:

How to actually choose

Are you an Xcel electric customer with a clean utility payment record? ClearPath is worth a serious look, especially if credit is the thing that's stopped you before.

Is a sale within a few years likely? Weigh the meter-transfer obligation and the disclosure duty. It may still be right. Know about it first.

Do you already have access to cheap capital? Use it. Nothing about the program beats a rate you already have.

Is the project over $50,000? Look at RENU, contractor financing, or a split.

Can you comfortably pay cash? Pay cash.

What we'll do

We'll tell you which paths you're eligible for, walk you through the program application if RENU or ClearPath is the fit, and give you a written, line-itemized quote either way.

What we won't do is quote you a monthly payment before we've quoted you a price. The number that matters is what the project costs. Everything else is arithmetic on top of it.

Common questions

Are windows actually eligible for ClearPath?

Yes. CCEF's eligible measures list includes windows and doors alongside insulation, air sealing, heat pumps, and electric water heating.

Does this put a lien on my house?

No. A Land Records Notice is filed with the county, which is a notice rather than a lien. The distinction matters and CCEF is explicit about it.

What happens if I sell?

The repayment obligation stays with the electric meter and transfers to the new owner with the electric service. You're required to disclose it to buyers. Some sellers pay it off first to keep things simple.

Can I pay it off early?

Yes, with no prepayment penalty.

Do you get paid more if I use the program?

No. We're an authorized contractor, which means we can submit the application and get paid by CCEF for the work. Our price for the project is the same either way.

What if I'm not an Xcel customer?

Then ClearPath isn't available to you, and we'll say so rather than walk you through an application that won't go anywhere.
