How Long Does Whole-House Window Replacement Take? | Quad Cities

Most whole-house replacement window installations can be completed in about one to two days once the custom windows have arrived and installation begins, although larger or more complicated homes can take longer. The number of windows, window styles, condition of the existing openings, hidden rot or water damage, bay and bow windows, weather, and trim work can all affect the schedule. Suburban Construction custom-measures every opening, custom-orders each window, and uses experienced full-time installers throughout the Quad Cities.

How Long Does It Take to Replace All the Windows in a House?

If you are considering replacing every window in your home, one of the first practical questions is:

“How long is my house going to be under construction?”

For many typical homes, the actual on-site replacement window installation can be completed in approximately one to two days once the custom windows have arrived and the installation crew gets started.

That does not mean every whole-house window project takes exactly the same amount of time.

A home with eight straightforward double-hung windows is very different from a house with twenty-five windows, multiple bay and bow units, difficult access, deteriorated frames, and extensive trim work.

For homeowners in Davenport, Bettendorf, Moline, Rock Island, East Moline, and throughout the Quad Cities, there are really two timelines to understand: the total process from estimate to installation and the amount of time the crew is actually working at your home.

The Short Answer

Suburban Construction says most homes can be completed in about one to two installation days.

A project may take longer when:

  • The home has 20 or more windows.
  • Bay or bow windows are involved.
  • Basement or egress windows require additional work.
  • Existing frames contain rot or water damage.
  • Structural modifications are required.
  • Interior or exterior trim needs significant repair.
  • Weather affects safe installation.
  • The openings are unusually difficult to access.

The number of windows matters, but the complexity of each opening matters just as much.

There Are Two Different Window Replacement Timelines

Homeowners often ask how long replacement windows take, but there are actually two different questions.

1. How Long From Estimate to Installation?

Replacement windows are generally custom measured and manufactured for the individual openings in your home.

Suburban Construction's process includes:

  1. Free in-home estimate
  2. Project approval
  3. Precise field measurement
  4. Custom manufacturing
  5. Installation scheduling
  6. Installation
  7. Final walkthrough

Production lead times and scheduling therefore happen before the crew ever arrives at your home.

2. How Long Will Installation Take at My House?

Once the windows are ready, many standard residential projects are completed in one to two days.

That is the timeline most homeowners are thinking about when they ask how long their house will be disrupted.

How Many Windows Can Be Replaced in One Day?

There is no responsible universal number because windows vary substantially in size, style, location, and condition.

A crew may move efficiently through a series of standard replacement openings while spending significantly more time on a single complex bay window or deteriorated opening.

That is why simply asking:

“How many windows can you install per hour?”

is not necessarily the best way to evaluate a window contractor.

Speed matters. Correct measurement, insulation, flashing, sealing, operation, and cleanup matter more.

What Happens During a Typical Installation?

Suburban Construction's published installation process includes more than simply pulling one window out and putting another one in.

For each opening, the crew generally needs to:

  • Protect the work area.
  • Remove the existing window.
  • Inspect the opening.
  • Prepare the opening for the new unit.
  • Set the replacement window.
  • Shim it level and plumb.
  • Secure the window.
  • Flash and insulate the opening.
  • Test operation.
  • Complete interior and exterior trim.
  • Caulk and seal perimeter joints.
  • Clean the area.

Review the Suburban Construction Window Installation Process

Does the Number of Windows Affect the Timeline?

Absolutely.

Suburban Construction specifically notes that a house with eight windows typically moves faster than a whole-house project with twenty or more openings.

But quantity is only the starting point.

Twenty straightforward double-hung windows may move more efficiently than fifteen windows containing multiple large specialty units.

Do Bay and Bow Windows Take Longer?

Usually.

Bay and bow windows are larger projecting systems and generally involve more installation work than a standard replacement window.

They can require additional attention to:

  • Support
  • Leveling
  • Roof or head details
  • Exterior finishing
  • Interior trim
  • Insulation
  • Weatherproofing

If your whole-house project includes one or more bay or bow units, expect the contractor to account for that in the schedule.

What About Basement and Egress Windows?

These can also require additional time depending on the opening and scope.

A straightforward basement replacement may be relatively simple.

Creating or modifying an opening for an egress window can be a much larger project involving masonry, excavation, framing, wells, drainage, or other work.

Replacing an existing window is different from creating a new or larger opening.

What Happens if the Crew Finds Rot?

This is one of the most common reasons an installation can take longer than expected.

Old windows can conceal conditions that are difficult to fully evaluate until removal begins.

Possible hidden problems include:

  • Rotted wood
  • Water-damaged framing
  • Deteriorated sheathing
  • Previous installation problems
  • Damaged exterior trim
  • Out-of-square openings

The correct response is not to rush through the opening simply because the project was expected to finish that afternoon.

If damaged material is discovered, fix the opening before covering it with a new window.

JR Girskis: The Goal Isn't to Win a Race

Brian “JR” Girskis, President and Owner of Suburban Construction, has worked full-time in the family business since 2002 and has served as President since 2007.

After decades around replacement window projects, one of the most important distinctions is the difference between an efficient installation and a rushed installation.

JR's approach is simple: homeowners should expect an experienced crew to work efficiently, but the schedule should never become more important than correctly fitting, insulating, flashing, sealing, and testing each opening.

Suburban Construction uses experienced full-time window installers who install windows every day. The company's installation process emphasizes proper fitting, flashing, insulation, sealing, cleanup, and a final walkthrough rather than simply maximizing the number of windows installed per hour.

Will My House Be Open to the Weather All Day?

Normally, no.

Experienced replacement-window crews generally work through openings individually rather than removing every window in the house at once.

The old window is removed, the new window is installed and secured, and the opening is protected before the crew advances through the project.

This helps limit the amount of time individual openings are exposed.

Can Windows Be Replaced During Cold Weather?

Replacement windows can often be installed during colder weather when conditions allow safe, proper work.

The same principle applies: openings are generally handled individually rather than leaving the entire house exposed.

Extreme weather can still affect scheduling, particularly when it interferes with safe installation, exterior sealants, access, or proper workmanship.

Does Interior Trim Add Time?

It can.

Some replacement installations can preserve much of the existing interior trim.

Others may require:

  • New casing
  • New stops
  • Sill work
  • Trim repair
  • Additional carpentry

The more finish carpentry involved, the more time the project may require.

What About Exterior Aluminum Capping?

Exterior finishing can also affect the schedule.

If windows require custom aluminum trim or capping, each opening takes additional time to finish correctly.

That finishing work is part of the completed installation and should not be treated as an afterthought simply because the new window is already sitting in the opening.

Can I Stay Home During Window Installation?

Usually, yes.

Replacement-window projects create noise and activity, but most homeowners do not need to move out of the house.

You should expect workers to need access to the interior side of every window being replaced.

How Should I Prepare My House?

A little preparation can help the crew work more efficiently.

Before installation day:

  • Move furniture away from the windows.
  • Remove fragile objects near the work areas.
  • Take down curtains and window treatments if requested.
  • Clear access to each opening.
  • Secure pets.
  • Discuss alarm sensors or other window-mounted equipment.
  • Ask the contractor whether anything outside the home needs to be moved.

Good access helps installers spend their time installing rather than moving furniture from room to room.

How Long Does Cleanup Take?

Cleanup should be part of the installation—not something left for the homeowner.

Suburban Construction's installation process includes removing old windows directly to its disposal trailer, cleaning debris, vacuuming sills, wiping glass, testing the windows, and completing a final walkthrough.

Installation is not finished when the final window is screwed into the opening. It is finished when the windows operate correctly and the work area has been cleaned.

What Happens During the Final Walkthrough?

Suburban Construction's process finishes with a walkthrough of the newly installed windows.

Homeowners can review:

  • Opening and closing
  • Lock operation
  • Tilt-in cleaning where applicable
  • Screen operation
  • Maintenance
  • Any final questions

The company's window installations are also backed by its lifetime workmanship guarantee.

Should I Replace All the Windows at Once?

You can, but you do not have to.

A complete whole-house project can be convenient because the disruption happens once and all the windows are updated together.

However, Suburban Construction also works with homeowners who replace windows in phases.

Phased replacement can make sense when:

  • Only some windows are failing.
  • You want to spread the investment over time.
  • One section of the house needs attention first.
  • You want to prioritize bedrooms or cold rooms.

A Realistic Whole-House Installation Example

Project Type Possible Installation Time
Smaller home with straightforward standard windows Often around 1 day
Typical whole-house replacement Often around 1–2 days
20+ windows May require additional time
Bay, bow, specialty, or difficult openings Additional installation time should be expected
Hidden rot or structural repairs Timeline depends on repairs required

These are planning guidelines rather than guarantees. The contractor should evaluate the actual openings before giving you a project-specific schedule.

Don't Confuse a Fast Installation With a Good Installation

Homeowners naturally want the project finished quickly.

But “we can install twenty windows in six hours” is not automatically a reason to hire someone.

Ask what happens during those six hours.

Are the openings being inspected?

Are the windows being shimmed level and plumb?

Are they being insulated and flashed?

Is the trim being finished properly?

Efficiency is good. Shortcuts are not.

Questions to Ask Your Window Contractor About the Timeline

  1. How many installation days do you expect for my house?
  2. How many installers will be on the crew?
  3. Are my window styles likely to require extra time?
  4. What happens if hidden rot is discovered?
  5. Will the old windows be removed and hauled away?
  6. Is interior and exterior trim included in the timeline?
  7. How does weather affect scheduling?
  8. Will my house remain secure at the end of each workday?
  9. What cleanup is included?
  10. Will we have a final walkthrough before the job is considered complete?

The Bottom Line: How Long Does Whole-House Window Replacement Take?

For many typical homes, the on-site replacement process takes approximately one to two days.

Smaller straightforward projects may be completed more quickly.

Larger homes, specialty windows, hidden damage, structural work, or extensive trim can extend the schedule.

Remember that the overall project takes longer because the windows must first be measured, custom manufactured, delivered, and scheduled.

As JR Girskis' approach emphasizes, the goal is not to install your windows as fast as humanly possible. The goal is to install them efficiently without sacrificing the details that determine whether they perform correctly for years to come.
