Testimonials

A reputation we've spent 25 years earning.

I wanted to take a moment and express our appreciation to the Windmill Construction team. Renovations of any sort can be stressful — as a business owner going through one, it could have been very disruptive and costly. The professionalism of your company, the positive attitude and work ethic of your staff, your flexibility around our store hours, and the exceptional quality of workmanship made our renovation experience a positive one. Henry — your ability to address every change and unforeseen challenge while adhering to the schedule was key to this project's success. Throw in a balanced budget and we'd like to say: you nailed this project.
Martin Timmers Owner — Ingleside Foodland
A lot of companies claim the old adage 'no job is too big or too small' — but with Windmill Construction they truly mean it. I have used them for many years for a variety of jobs — from patio walkways and design suggestions to full excavations and complete kitchen renovations. They did an outstanding job on a double garage they built for me. The Windmill team approaches every job with the same commitment to quality and customer service. I appreciate their honesty, integrity and the information they provide me to make informed decisions about my renovations. I can count on them to ensure the job is done on time, within budget, and to my complete satisfaction.
