Simple Repairs May Be Included

If replacement parts or a larger repair are needed, I will explain the findings and provide pricing before proceeding.

Why Choose Engineer Handyman?
Root-Cause Thinking
I try to understand why something failed instead of immediately replacing parts or masking symptoms.
Clear Communication
I explain scope, pricing, limitations, and findings so you can make an informed decision before additional work begins.
Careful Verification
When applicable, I test operation, check for leaks, verify electrical readings, and document the finished result before leaving.
Clean Workmanship
Layout, alignment, hardware, wiring, cleanup, and the finished appearance all matter—not just getting the item installed.
Honest Scope Limits
If a project requires work I do not offer, a permit, or a licensed contractor, I will tell you rather than taking on work outside my scope.
Bundle-Friendly Pricing
Several compatible projects completed during one visit can often be priced more efficiently than separate service calls.
Getting an Estimate Is Simple
Most common jobs can be scoped faster when I can see the existing condition before scheduling.
Text Photos & Details
Send a few clear photos, your general location, and a short description of what you need done.
Receive Pricing
If the scope is clear, I can usually provide an estimate or starting price before the visit. Diagnostic jobs are quoted accordingly.
Schedule the Work
Once the scope and price make sense, we choose an available service time and complete the project.
An Engineer's Approach to Handyman Work
I’m Luis, an electrical engineer and Tucson homeowner who started Engineer Handyman to give homeowners a more technical, detail-oriented option for common repairs and installations.
I approach projects the same way I approach engineering problems: understand the issue, identify the right solution, perform the work carefully, and verify that everything operates correctly before leaving.
I also believe credibility means being upfront about limits. I do not take on work simply because someone is willing to pay for it. If a project is outside my experience, requires services I do not offer, or needs a licensed contractor, I will say so.
- Clear, upfront pricing
- Detailed estimates when needed
- Professional respect for your home
- Troubleshooting before unnecessary replacement
- Honest recommendations and scope limits
