About TrueLine
Where every line is true.
A new company, built on experience. One team that sells, supplies and installs, and stands behind the work from the first measurement to the final walkthrough.
Our Story
A new company, built on experience.
TrueLine Windows, Doors and Renovations was founded in 2026 in Metro Atlanta by João Pelegrini and his partner Silvio. The company is new, but the people behind it are not. João has spent the last three years building businesses in the U.S., and Silvio brings more than a decade of hands-on experience in construction and installation.
Why We Started
One company that owns the result.
We kept seeing the same problem: homeowners juggling a supplier, an installer and several subcontractors, with nobody truly owning the result. When something went wrong, everyone pointed at someone else.
We started TrueLine to change that: one company that sells, supplies and installs, and stands behind the work from the first measurement to the final walkthrough.
How We're Different
No handoffs. No finger-pointing.
- Supply + installation, one point of contact. We source the product and we install it. No handoffs, no finger-pointing, no subcontracting surprises.
- Over a decade of field experience. Our installation side is led by a partner with 10+ years in the trade, so the details that matter (measurements, flashing, sealing, finish) are handled by someone who has done it thousands of times.
- Clear, itemized proposals. You see exactly what's included and what you're paying for, with no vague allowances or hidden extras.
- Fast turnaround. Detailed quotes delivered quickly, so you can decide with confidence and keep your project moving.
- Quality materials from trusted manufacturers. We match the product to your home, your budget and your style.
How It Works
A simple process, from first call to final cleanup.
Whether you are replacing one door or upgrading your whole exterior, every project follows the same four steps.
Free estimate
We visit your home, listen to what you want to change, and look at your windows, doors, or outdoor space. You get a clear recommendation and a no-obligation estimate.
Measure
When you are ready to move forward, we take precise final measurements so every product is ordered to fit its opening.
Install
Our crew removes the old, installs the new, and seals and finishes each opening or structure the right way.
Cleanup
We clean up the work area, check that everything operates correctly, and walk you through the finished project.

Why "TrueLine"
Straight, level, aligned.
In construction, everything depends on the line being true: straight, level, aligned. That's how a window seals, a door closes and a deck lasts. It's also how we run the business: accurate quotes, honest communication and work that holds up over time.
