Professional Garage Demolition in Boulder, CO
Garage demolition is the process of taking down an entire garage structure, including the walls, roof, foundation, and slab. Whether you have a detached garage that is falling apart or an old carport that needs to go, professional garage demolition removes the structure safely and clears the space for your next project.
At 303 Demolition, we handle garage demolition for homeowners and property owners throughout Boulder, CO. We take down wood-frame garages, metal garages, and block garages of all sizes. Our crew manages every part of the job, from disconnecting utilities to hauling away debris.
An old garage that is leaning, rotting, or structurally compromised is a liability. It can attract pests, lower your property value, and pose a safety risk. Removing it opens up your lot for a new garage, an addition, a garden, or simply more yard space.

Detached Garage Removal in Boulder, CO
Detached garage removal is one of our most requested services in Boulder. Many older homes in the area have detached garages that were built decades ago with materials and methods that no longer meet current building standards. These structures deteriorate over time and eventually need to come down.
We remove detached garages of all sizes, from single-car structures to oversized two-car garages with workshops or storage lofts. Our crew dismantles the structure section by section, starting with the roof and working down to the foundation. We can also remove the concrete slab if you want a completely clear lot.
Why Garage Demolition Matters
A deteriorating garage affects your property value, safety, and curb appeal. Garages with failing roofs can collapse. Garages with damaged foundations can shift and lean. Pest infestations, mold, and fire hazards are all common in old, neglected garage structures.
Removing the garage eliminates these risks and gives you control over how to use the space. Many homeowners in Boulder replace an old garage with a new, code-compliant structure. Others convert the space into a patio, garden, or accessory dwelling unit.
When Do You Need Garage Demolition?
You need garage demolition when the structure is unsafe, heavily damaged, or no longer serving its purpose. Signs that it is time include a sagging roof, cracked or shifting foundation, visible rot in the framing, and doors or walls that no longer close properly.
Garage demolition is also needed when you are building a new garage, adding on to your home, or redesigning your property layout. If the existing garage is in the way of new construction, it needs to come down first.
If your garage has a concrete slab or driveway connected to it, we can handle the concrete removal as part of the same project. We also offer shed demolition if you have other structures on the property that need to be removed.
How Much Does Garage Demolition Cost in Boulder, CO?
Garage demolition costs depend on the size of the structure, the material it is built from, whether utilities need to be disconnected, and whether the foundation or slab needs to be removed. A small single-car detached garage costs less to demolish than a large two-car garage with a concrete foundation.
