How To Choose a Window Company in Boulder

It's essential to find a window installer that aligns with your specific values, needs, and preferences. Consider the following areas during your search:

Window Cost by Type

When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing cheap windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The final cost of your replacement windows will hinge on the particular materials, styles, and sizes you need. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. It's recommended to consult a vetted window installer to determine your most suitable options.

To help you form a rough estimate, this table shows the typical cost of the most common residential window types.

Window TypesAverage Cost
Arched$216-$1326
Awning$312-$871
Bay$720-$5345
Custom$320-$890
Casement$249-$1445
Double-hung$116-$752
Egress$213-$533
Glass Block$42-$540
Picture$187-$1385
Single-hung$84-$1425
Skylight$106-$1286
Sliding$245-$1247
Storm$50-$352
Transom$261-$546

Window Material Cost

You'll also need to pick a window material. Homeowners frequently base their decision on energy efficiency objectives, the local climate and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows up-front, but you'll need to invest in regular maintenance to prevent the frame from warping and wear. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost
Aluminum$50-$1425
Composite$514-$1156
Fiberglass$84-$720
Vinyl$173-$1603
Wood$257-$1445

Other Window Replacement Costs

Your total cost for new windows will also include applicable warranty fees, permit-related costs (if required), and labor. Make sure to discuss each of these aspects with a sales representative before committing to a window company.

Experience and Training

Peruse a company's website and contact a representative to learn more about its product and service offerings, pricing, and guarantees. Many window companies also keep online portfolios that present past projects.

Ensure that the company specializes in window replacement. The more dedicated instruction its staff has, and the longer it has been active, the more likely it will deliver top-notch service.

Licensing and Credentials

Colorado's contractor licensing requirements are distinct from other states. There is no statewide authority that licenses window companies, but they might still need licenses from local municipalities in which they operate. Both Denver and Colorado Springs license window installers, treating them as either general contractors or building contractors. For other areas, consult your local government.

Types of Windows Offered

No two businesses offer the same window styles and materials. Find one that's an expert in the type you want for your home.

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

Customer Feedback

One of the easiest ways to vet a company is to check what other customers have written about their experiences. Read customer reviews on sites such as Trustpilot, Google, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Referrals can also help you in your company search. Ask each company you're interested in for a list of references, and talk to family and friends about who they use for window installations.

Frequently Asked Questions About Window Replacement in Boulder

Why should I hire a professional to install or replace my windows?

By working with a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation team is well-equipped with the right tools and skills to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored help to make the most of your new windows

What time of year should I replace my windows?

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

How long does a window replacement job take?

The length of a window replacement project depends on several factors. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes around an hour per window. However, larger windows or more complex installations may require additional time.
