A tight front door keeps drafty air out and your home secure, while a smart lock means no more fumbling for keys in the cold. Most installs take just a single day, and scheduling the work during the off-season winter months usually means lower installer rates and faster booking.
The average job runs about $1400 for the door, hardware, and labor. Getting multiple quotes keeps contractors honest, and spreading that cost out over time makes the hit to your bank account much easier to handle.
A 0% intro period gives you time, but it isn't free money. If you still have a balance when the 18 months end, regular interest kicks in on whatever is left, so stick to your monthly plan.
