Garage Additions
Built Right
Need more space for your vehicles, tools, or storage? At Bump Out Addition Des Moines, we build garage additions that work with your existing home — designed for older Des Moines houses that need a real upgrade.
Professional Garage Additions in Des Moines
Our garage addition services cover everything from attached single-car additions to detached multi-car builds. We work on older Des Moines homes regularly, so we know how to tie a new structure into an existing foundation and roofline without shortcuts.
We use both new and quality aftermarket materials — framing, siding, roofing, and flooring — to match your budget without cutting corners on durability. Every garage we build is designed to hold up through Iowa winters and last for decades.

Our 5-Step Garage Addition Process
We begin by understanding your vision, needs, and budget — at no cost to you. We assess your property and talk through attached vs. detached options.
Together we create a plan that fits your lot, your home's existing structure, and your budget — with material options that range from new to quality aftermarket.
Our team handles all local Des Moines permits and approvals required for your garage addition so the project starts clean and stays on schedule.
We handle everything from foundation to final finish — framing, roofing, siding, doors, and flooring — ensuring minimal disruption to your daily life.
Once the project is complete, we walk through every detail to ensure you are completely satisfied before we consider the job closed.
Common Reasons Homeowners Choose a Garage Addition
-
No Garage or Not Enough Space
Many older Des Moines homes were built without a garage or with a single-car setup that no longer meets the family's needs. A garage addition solves that permanently.
-
Aging Infrastructure
Old detached garages in the area often have rotted framing, failing roofs, and cracked slabs. Sometimes a full replacement is the smarter move over repeated repairs.
-
Need a Workshop or Storage Space
A garage addition gives you room for tools, hobbies, lawn equipment, or extra storage — keeping clutter out of the house and off the driveway.
-
Increase Property Value
Buyers in Ankeny, Urbandale, and West Des Moines consistently prioritize homes with garages. Adding one is one of the highest-return improvements you can make to an older home.
Repair, Replacement & Addition Options
Repairing Existing Structures
If your current garage has a leaking roof, damaged siding, or a cracked floor, we address those issues first. Good repairs on a solid structure can extend its life significantly without a full rebuild.
Replacing Old Features
Old garage doors, windows, and siding can be swapped out for energy-efficient replacements. We work with new and aftermarket options to fit your budget and improve performance year-round.
Full Garage Addition
From attached single-car additions to detached two-car builds, we handle the entire project — foundation, framing, roofing, siding, doors, and flooring — from start to final walkthrough.
"Our house never had a garage and we'd wanted one for years. Bump Out Addition Des Moines built us an attached two-car garage that looks like it was always part of the house. Couldn't be happier with how it turned out."
— Greg & Karen M., Urbandale, IA
