A new front door changes the way the house feels every single time you walk in. Drafts stop, the deadbolt feels solid, the curb appeal jumps, and you stop apologizing to guests before they even step inside. The install itself is usually a one-day job, and the door starts doing its job the second the crew leaves.
Fall is when door companies and big-box stores start running home improvement promos to fill slow weeks before the holidays. That overlap of lower prices and a no-interest financing window is the whole game here. Get two or three written quotes so you can compare the price, the door spec, and the warranty side by side, not just the total.
The intro APR window is a deadline, not a discount. If a balance is still sitting on the card after 15 months, the standard APR kicks in and the interest starts adding up on the original purchase. Pay it off, or set a payoff plan, before the clock runs out.
