Tired of Living in a Home That Doesn't Work or Feel Like You?

The kitchen is too tight to cook or host in. The basement still sits unfinished. The whole house feels cramped and dated, and the projects you meant to start this year keep slipping into next. Most homeowners we meet aren't stuck because they can't decide. They're stuck because the last few contractors didn't call back, couldn't give a straight answer, or quoted one number and charged another.

We get it. Letting someone into your home for a six-figure project is a real risk, and you shouldn't have to lower your expectations just to get it done right.

What We Build

  • A gray, three-story house with a brick foundation, multiple windows, and a white garage door, set against a partly cloudy sky with green lawn in the foreground.

    Home Additions

    Add the square footage your house is missing. Full additions managed from groundbreaking to the final walkthrough.

A Pittsburgh Contractor Who Actually Fulfills Their Promise

We've heard the same stories for years: the contractor who stopped answering the phone, the quote that kept climbing, the crew that left a mess and never came back. Quinlan Contracting was built to be the opposite. We answer the phone, we show up, we hold to our price, and one in-house crew sees your project through to the end. That's why homeowners across the Pittsburgh suburbs have left us 40-plus five-star reviews.
