A new front door with sidelights changes your entire entryway. It cuts out cold morning drafts, floods the foyer with natural light, and takes a good crew less than a day to install. The smartest time to order is late winter, when home centers discount older stock and carpenters have room on their schedules. Always get at least three quotes before anyone pulls out a tape measure.
A full setup runs about $2,400 for the door unit, glass panels, and installation. Instead of draining an emergency fund to cover it all at once, you can spread the bill across a year and a half without adding interest charges to the total.
The 18-month window is a firm deadline, not free money. If you still owe money when that period ends, regular interest rates apply to whatever balance remains. Keep your monthly auto-pay set to $133.33 from the start so the balance is gone before the promotional period expires.
