Window and Door Replacement Financing

When you look at the cost to replace your windows, be sure they’re backed by a lifetime warranty. We’re one of the few replacement window companies that offer this, along with extremely competitive pricing and monthly payment options.

Unlike other replacement window contractors, we don’t practice high-pressure tactics. Instead, we provide free in-home consultations where we uphold our strong company motto of honesty above reproach.

4 Flexible Payment Options for Your Project

At Window Source of Houston, we understand the importance of having flexible financing options to suit your needs. That’s why we offer four convenient payment plans for your home improvement projects.

Choose the payment plan that best fits your budget and get started on enhancing your home today!

Payment options

  • Split payment plan. Windows and doors: pay 50% upfront and the remaining 50% upon project completion.
  • 0% interest payments. Enjoy the benefit of no interest with flexible monthly installments ranging from six months up to five years. This option is available for loan amounts for residential window and door projects up to $100,000.
  • Fixed interest rates. Opt for a low-interest loan starting at just 2.99%, with repayment terms from five to 25 years. Alternatively, choose a higher interest rate to increase the discount on your entire project’s cost.
  • Options for poor credit scores. We believe everyone should have access to our services, regardless of circumstances. For those with FICO scores below 580, we may still have a financing option available for you.

“My husband and I are obsessed with our new windows from The Window Source!! They were delivered in a very short time frame and only took a day to install. Great install crew, very clean, efficient, and paid attention to detail when sealing everything off.”

“I got several quotes, and Jairo was the only one who brought samples and took the time to give us a demonstration. The office stayed in communication with me every step of the way… Edwin’s installation team worked quickly and professionally.”

“Replacing my parents’ original builder-grade windows in their 25+ year old home was one of the best investments they’ve made… They’ve already noticed lower electric bills, less outside noise, and a cooler, more comfortable home that’s much easier to keep at a consistent temperature.”
