Exterior Door InstallationDoor and Window Installation From Estimate to Cleanup
Every Lopez X Construction job includes the same five things.
A Free In-Home Estimate
Omar inspects your windows and doors, shows you a sample window, and gives you a written quote the same day.
Measured to 1/16 of an Inch
We measure every opening, and the manufacturer builds each window and door to fit it.
OSI Certified Sealing
Our installers are certified by OSI to seal windows and doors against water and weather.
Trim Work When It's Needed
Most installs leave your trim alone, and we install new base and casing when a job needs it.
Permits When Required
Most window and door jobs don't need a permit, and we pull one when your city or county requires it.
Built to Your Openings
Custom-Built to Fit Your Existing Openings
Lopez X Construction measures every opening to 1/16 of an inch, and the manufacturer builds each window and door to those measurements. Most of the time the existing frame stays in place, so your trim, drywall, paint and siding stay untouched. That fit is how our crew installs 10 to 15 windows in one day.

Frequently Asked Questions
Is the estimate free?
Yes. The in-home estimate is free. Omar comes to your home, inspects your windows and doors, and gives you a written quote. There is no trip fee.
What happens at the in-home estimate?
Omar asks what you need, inspects each window and door, and checks whether it needs replacing. He brings a sample window you can handle and test. He gives you a quote the same day.
What is the difference between a standard and a custom window?
Every window we install is custom-made to fit its opening. Custom options add color, interior and exterior paint, and hardware finishes like black, silver or bronze. Size is the most common custom detail.
Which brands do you install?
We install Alside windows, including the Mezzo and Sovereign lines, and ProVia entry, French and patio doors.
Do you need a permit?
Most window and door replacements don't need a permit. When your city or county requires one, we pull it. A permit usually takes about a week.
Can you make a window opening bigger?
Yes. We can enlarge an opening or cut in a new window. We install new base and trim casing around it without tearing out the whole wall.
Do you offer financing?
Yes. We offer financing through Hearth, with 0% options for qualified buyers. See our financing and warranty page for how it works.
