WHY HOMEOWNERS & PROPERTY OWNERS CHOOSE US
Rochester Hills’ Trusted Home Addition Contractor

US Tech Inc. has been the addition contractor Oakland County homeowners and property owners turn to for that exact reason since 1992, managing residential home additions and commercial building expansions from the first sketch to the final walkthrough.

Because we run a true design-build operation, the same crew that pours your foundation is still on site hanging drywall and trimming out the final details, whether we’re framing a second story above an existing roofline or extending a commercial building’s footprint. There’s no juggling separate architects, framers, and finish crews on your end — we coordinate it all, so the finished addition reads as part of the original home rather than an obvious add-on.

REAL CLIENT STORY
What Rochester Hills Homeowners Are Saying
Frank, Mike, and the rest of his team did a great job bringing our lower level (family room, laundry room, half bath, and spare bedroom) out of the 1970s and into the present. They did a great job protecting the rest of the house from dust and debris while they worked. The final result was better than I could have imagined, and Frank and I have already had discussions about having him back to work on the other problem areas of our house.
Frank and his crew did a great job on the flooring, drywall, painting, etc. Communication was great and they did a good job of keeping costs from creeping. They did a good job of keeping the timeline as best as could be given the supply shortages.
Frank and his team did great quality work on our basement! Frank took care of the hiccups expeditiously and he and his team made us feel well taken care of. Frank’s input with design and ideas were very helpful too! We are extremely pleased and will definitely hire them again for future jobs. Thank you for exceptional service!!
The US-TECH INC. BUILDERS Team did excellent work, with rebuilding my home garage. A couple of companies wanted to charge me for a full tear down and new build. US TECH came thru, reviewed the damaged areas, and then estimated to replace and rebuild those problem areas. Professional and Personable Team, great solid work and service, great pricing.
Frank and his crew (Mike, AJ, Danny and Jovan) did awesome work at our home. During the construction process, we asked many questions and they were always willing to take the time to answer and address them all. We are very happy we chose US-Tech Builders to complete our renovation. Highly recommend!
Frank and his team did an awesome job of remodeling our rehab project in Shelby Township. He was fair with his pricing and even went beyond the scope of work to do other repairs that he was not compensated for. The work was completed in a timely fashion and I am very pleased with the results.
Could not have been more pleased! Frank and his associate Mike made it possible in a very short amount of time. Contact was immediate, response was like I was family, commitments were readily made and kept, work was efficiently delivered and space was clean at the end, price was so good, follow up was quick. I will not hesitate to recommend Frank and his company to anyone.
HOW IT WORKS
What to Expect When You Build a Home Addition With Us
Five straightforward steps take your addition from idea to finished space:
A member of our team walks your Rochester Hills property, talks through how you’ll use the extra space, and sizes up what’s realistic for your lot. No cost, no obligation.
Next we map out the addition’s footprint, room layout, and finishes, then put together a line-item price breakdown so you can see exactly where every dollar of the budget goes.
Our office pulls the required municipal building permits, confirms zoning setbacks with Oakland County, and lines up materials in advance, so the crew isn’t waiting on anything once ground breaks.
The same crew stays on your job from foundation pour through framing, roofing, and finish work, keeping a steady presence while containing dust, noise, and debris away from your home.
Before we call the project finished, we walk the completed addition with you room by room, addressing any punch-list items on the spot so you’re fully satisfied with the results.
