About CheckMac | Local Computer Repair & Upgrades in Dubuque, IA

Our Story

A Local Workshop Dedicated to Quality Tech Repairs

CheckMac was founded on a simple principle: people shouldn't be forced to buy a new $1,500 computer just because their existing laptop is running slow, has a dying battery, or caught an annoying browser virus.

At our workshop located at 1015 Wilson Ave, Dubuque, IA 52001, we test, diagnose, and upgrade MacBooks, Windows PC laptops, and iPhones right on our bench. We don't ship your device to third-party regional hubs or make you wait weeks for simple repairs.

Because we are an independent repair center, we have the flexibility to offer cost-effective component-level repairs and custom high-speed NVMe storage upgrades that authorized dealer stores often refuse to carry out.

Our Principles

The CheckMac Standard of Service

What sets us apart from big-box retail electronics counters.

100% Upfront Transparency

We provide clear, written diagnostic findings and itemized repair estimates before starting any work. If a repair is not economically practical for your device, we will be the first to tell you honestly.

Strict Data Confidentiality

Your personal photos, documents, financial records, and emails remain entirely confidential. We adhere to professional data handling procedures and never inspect your personal files.

Solid 90-Day Guarantee

Every replacement battery, SSD drive, RAM module, and screen repair is backed by our full 90-Day Parts & Labor Warranty. If something isn't right, we fix it promptly at no additional cost.

Fast Local Turnaround

We understand how crucial your computer or phone is for work, school, and family. Most malware removals and SSD upgrades are finished within 24 hours, and iPhone screen repairs in under 2 hours.

Electronic Waste Reduction

By upgrading existing computers with modern solid-state drives and fresh batteries, we help prevent functional consumer electronics from ending up prematurely in local landfills.

Professional ESD Benches

Our workshop is outfitted with electrostatic discharge (ESD) safe mats, grounded precision tools, microscopic inspection stations, and temperature-controlled soldering irons.
