Windows FAQs

The cost of professional window installation varies depending on the type of window, materials, and labor involved. On average, homeowners can expect to pay between $300 and $1,200 per window, including installation. Basic single-hung windows tend to be on the lower end of the scale, while custom, energy-efficient, or large-sized windows can push costs higher. Replacing multiple windows in a home can sometimes result in package discounts, so it’s worth discussing with your service provider. Be sure to ask for a detailed quote that breaks down labor and material costs for full transparency.

The timeline for installing new windows largely depends on the number of windows, their size, and whether it's a replacement or a new construction installation. On average:

  • Standard replacement windows can be installed in 1-2 hours each.
  • A full house installation generally takes 1-3 days for a professional team.

Custom-shaped windows, structural modifications, or unforeseen issues (like rotting wood) might extend the timeline. Discuss your project specifics with your contractor for a more accurate estimate.

When hiring a window contractor in Denver, you should ensure they have the proper credentials to operate in the area. Look for:

  • A valid state or local contractor’s license for window installation.
  • Liability insurance to protect your property.
  • Workers’ compensation insurance to cover employees on-site.

You can verify licenses through the relevant state licensing board for contractors. For example, you can check with the Contractors State License Board (CSLB) in California or double-check local regulations in Denver for specific requirements. Proper licensing ensures accountability and compliance with building codes.

Be cautious if you encounter any of the following red flags during your search for a window professional:

  • Lack of licensing or insurance: Reliable contractors will provide proof of their credentials without hesitation.
  • No written estimate: A verbal quote without documentation may lead to unexpected charges later.
  • Unrealistically low bids: A significantly lower price could indicate substandard materials or untrained labor.
  • High-pressure sales tactics: Legitimate contractors will give you time to consider options without coercion.
  • Vague contracts: Ensure project details, timelines, and costs are outlined clearly in any agreement.

Do thorough research and don’t hesitate to ask questions; trust your instincts if something feels off.

Yes, energy-efficient windows are often worth the investment in both the short and long term. They help reduce energy bills by minimizing heat loss during winter and blocking heat gain during summer. These windows typically feature:

  • Double or triple glazing for added insulation.
  • Low-E glass coatings to reflect heat.
  • Gas fills like argon for improved thermal performance.
  • Durable frames made from vinyl, fiberglass, or composite materials.

Though energy-efficient windows may cost more upfront, they often pay for themselves over time through energy savings and can add value to your home.

To get an accurate estimate for your window installation project:

  1. Determine your needs: What type of windows do you need (e.g., standard, custom, energy-efficient)?
  2. Measure windows: Have your contractor take exact measurements to ensure precision.
  3. Specify materials and features: Discuss the frames, glass, and hardware you prefer.
  4. Request multiple quotes: Compare at least 2-3 estimates from reputable contractors.
  5. Inquire about warranties: Ask which warranties cover labor and materials.

Ensure the estimate includes a breakdown of labor, materials, and potential disposal fees, so there are no surprises later.

Before hiring a window contractor, consider asking these important questions:

  1. Are you licensed and insured in Denver?
  2. Can you provide references or examples of past work?
  3. What warranties do you offer on materials and labor?
  4. What is the expected timeline for my project?
  5. How will you handle disposal of old windows?
  6. Are there any potential additional costs I should know about?

Getting clear answers to these questions will help you make an informed decision and ensure you’re working with a professional.

The main difference between full-frame replacement and pocket replacement lies in the scope of the project:

  • Full-frame replacement: The entire window—including the frame, trim, and sometimes surrounding studs—is removed and replaced. This method is ideal for old or damaged frames or if you want to change the size/shape of your window.

  • Pocket replacement: Only the window itself is replaced, leaving the existing frame intact. This is a quicker, less invasive option suitable for windows with solid, undamaged frames.

Discussing your project goals with a contractor can help determine the right option for your needs.

To ensure a smooth window installation process, follow these preparation tips:

  • Clear the area: Remove curtains, blinds, and decorations near windows.
  • Move furniture: Create clear access to the installation site.
  • Protect floors and valuables: Lay tarps or cover floors to guard against dust and debris.
  • Deactivate alarms: Temporarily disable window sensors in security systems.
  • Communicate with the contractor: Discuss parking and access arrangements for their team.

Being prepared can save time and reduce stress on installation day.

  • Bay and bow windows: Extend outward for added space and natural light.
  • Picture windows: Large, fixed windows to frame views.

Reviews for Window Pros

Fogged Windows? Not Anymore!
Our upstairs bedroom windows were completely fogged over, making it impossible to enjoy the view. Window Pros replaced the panes in less than a day, and the cost was way less than I thought it would be. Now the room is brighter, and we don’t have to deal with drafty nights anymore!

Sealed Tight Before Winter
Living in Denver, I was worried my old window seals wouldn’t hold up for another winter. Window Pros came out the next day, gave me an honest assessment, and had everything fixed by the weekend. My heating bill has already dropped, and it’s only midseason!

Crisis Averted, Fast!
A rock cracked our front bay window the night before hosting a big family dinner. Window Pros showed up that morning, replaced the glass quickly, and even cleaned up the mess. The house looked perfect by party time, and the price was super fair!
