Custom-Fit Windows vs Tear-Out Installs

Lopez X Construction measures every opening to 1/16 of an inch, and the manufacturer builds each window and door to fit it. Most of the time the existing frame stays in place. This is called pocket replacement.

A tear-out install removes the window down to the studs to fit a standard size. That means new framing, drywall patching, new trim and paint, and sometimes siding repair. Each of those adds cost, adds another trade to schedule, and keeps your house torn up for days or weeks.

Signs It's Time to Call a Window and Door Contractor

Most of the windows we replace in Forest Hills are original wood windows or builder-grade vinyl that has worn out. Most of the doors are old original wood doors.

  • Fog Between the Panes

    Fog or condensation between the glass means the seal has failed.

  • Windows That Stick

    A window that is hard to open, close or lock needs replacing.

  • Sashes That Drop

    Older windows can slam down when you open them.

  • Drafts and Light

    You feel air through the frame or see light between a door and its seal.

  • Leaks and Wet Drywall

    A known leak, a wet spot on the drywall or rotted wood means replace it soon.

  • Heat and Cold Coming Through

    You feel the outside temperature through the glass or the door.

Frequently Asked Questions

How long does a window or door project take?

Most window and door projects take one day. Our crew installs 10 to 15 windows in a day because every window is built to fit its opening. Larger projects can take two days, depending on how many windows and doors you replace.

Do you work from the inside or the outside?

We work from both, about half and half. It depends on the window or door and how it was first installed. Omar tells you which side we'll work from at your estimate.

Will new windows or doors need new trim inside?

Nine times out of ten, no. We measure every opening to 1/16 of an inch, so the new window or door fits without replacing your trim. If your trim is damaged and you want it replaced, we can do that too.

How do I know I need new windows?

Fog between the panes, windows that are hard to operate, and air coming through the frame are the most common signs. Sashes that drop when you open them and warped frames are signs too.

When should I replace windows right away?

Replace windows soon if you have a known leak, a wet spot on the drywall under a window, or rotted wood in the frame. Water that gets into the wall causes more damage the longer it sits.

Do you offer financing?

Yes. We offer financing through Hearth, with 0% options for qualified buyers. You can check your options without a hard credit pull. See our financing and warranty page for details.

What does your warranty cover?

Every window and door carries a lifetime warranty backed by the manufacturer. It covers the glass, screens and hardware, and our labor is included. If a ball breaks the glass, the glass pack is replaced for free.
