How To Choose a Window Company in Castle Rock

It's essential to find a window replacement company that meets your unique values, needs, and preferences. Consider the following traits during your search:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with performance is important. Although top-of-the-line replacement windows may come with a higher initial price tag, they often yield better long-term value due to their increased lifespan. The age of your home, together with the materials, sizes, and styles of replacement windows you opt for, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. It's recommended to consult a vetted window installer to decide on your most suitable options.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window TypesAverage Cost
Arched$236-$1450
Awning$342-$952
Bay$788-$5846
Custom$350-$974
Casement$272-$1580
Double-hung$127-$822
Egress$233-$583
Glass Block$46-$591
Picture$205-$1515
Single-hung$92-$1559
Skylight$116-$1407
Sliding$268-$1364
Storm$55-$385
Transom$285-$597

Window Material Cost

Materials also help determine a window's cost. You might select a material based on the local climate, your desired look, and your energy efficiency goals. For example, windows made of wood can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.

Window TypesAverage Cost
Aluminum$55-$1559
Composite$562-$1264
Fiberglass$92-$788
Vinyl$189-$1753
Wood$281-$1580

Other Window Replacement Costs

Your total cost for window replacement will also include warranty fees (if applicable), permit application fees, and labor. Make sure to discuss each of these elements with an estimator before committing to a window company.

Experience and Training

The longer a window company has been in business, the better its workmanship will likely be. Contact a company representative to learn more about its public and private credentials, experience, and guarantees. Company websites often keep photo galleries showing off previous work technicians have done.

Licensing and Credentials

Colorado's contractor licensing requirements are unique among states. There is no single regulatory body that licenses window companies, but they might still need licenses from local municipalities in which they operate. Both Colorado Springs and Denver license window installers, treating them as either general contractors or building contractors. For other areas, contact your local authorities.

Types of Windows Offered

No two window companies offer the same window types and materials. Find one that specializes in the type you want for your home.

Finally, pay close attention to the materials that a provider uses. Each window frame material has a different energy efficiency level, life span and price point. A company will usually specify whether the windows they mount use composite, fiberglass, vinyl, wood, or metal.

Customer Feedback

Perhaps the best way to screen window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Yelp, Trustpilot, and Google Speak with people you know who have used a company you're interested in, and ask a representative for a copy of its reference list.

Frequently Asked Questions About Window Replacement in Castle Rock

How could new windows help my energy efficiency?

In Castle Rock specifically, most homeowners using efficient windows cut their carbon emissions by 460 pounds each year. This means they save $440 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By installing new, more efficient windows, you can improve your home's energy efficiency and lower your electricity bills.

What time of year should I replace my windows?

Window replacement can be performed year-round. However, the installation process may be different based on the season. Costs are often more affordable in winter when demand is reduced. Keep in mind, however, that this could overexpose your home to the elements. Speak with a licensed window professional to determine the best climate conditions for your replacement project.

Do window companies have guarantees or warranties for their work?

Window companies often provide warranties for the work they do. Each typically covers issues with workmanship and materials for a specified period of time. It's essential to confirm the specific terms of the warranty with a window company before you sign a contract.
