The Garage: what every upgrade costs

By Dan Whitlock, Home Projects Editor · Updated July 2026

The Garage

The garage is where home upgrades get personal: it's the one room you're allowed to treat like a project.

These calculators price the working parts (a spring that just snapped, an opener that predates smartphones), the floor under it all (epoxy over a sound slab, or a new slab where there isn't one), and the newest arrival: a level 2 EV charger, quickly becoming the garage's most-used appliance.

Get quotes from local pros

Angi is a national marketplace for home services. You describe the job, and door contractors who work in your area contact you with their own quotes. Requesting quotes is free and you are never obliged to hire anyone.

Angi pays us a referral fee for a completed service request. The fee comes from Angi, not from you, and it does not change the estimates on this page.

How these numbers are compiled

Every range is the typical installed cost most homeowners pay, cross-referenced against published 2026 cost guides and contractor databases, then pressure-tested against our own calculators. They are planning figures, not bids. Read our full methodology →
