How To Choose a Window Company in Boulder

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

Window Cost by Type

When you're shopping for new windows, it's essential to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing economy windows could actually increase your overall cost, due to their shorter lifespan and more intensive maintenance needs. The total cost of your window replacement will depend on the specific styles, materials, and sizes you need. Transom windows are inexpensive with their simple size and straightforward form factor, while a custom-cut arch window in a master suite will cost more. An installer can guide you through choosing the solutions that fit your preferences.

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 often base their decision on the local climate, aesthetic preferences and energy efficiency objectives. 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 contractor will factor the price for your windows and the value of their services into its total estimate. Make sure to assess the cost of labor, warranties, and any other extra expenses that your project may entail.

Experience and Training

The longer a window provider has been operating, the better its workmanship will likely be. Talk with a company representative to learn more about its public and private credentials, experience, and guarantees. Company websites often have photo galleries demonstrating previous work technicians have done.

Licensing and Credentials

Colorado's contractor licensing requirements are distinct from other states. There is no central board that licenses window companies, but they might still need licenses from the cities and counties in which they operate. 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 contractors offer the same window designs and materials. Find one that's an expert in the type you want for your home.

Also, check the kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include aluminum, fiberglass, vinyl, composite and wood.

Customer Feedback

Reading other customers' stories is an interesting way to screen different window replacement companies. Read customer reviews on sites such as Google, Trustpilot, 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?

Replacing your windows is an important purchase that greatly impacts your home's comfort and energy performance. Hiring a professional window company to manage your project ensures your windows will fit correctly, perform optimally, and be properly sealed. Companies also typically include a warranty that takes care of required maintenance and most future repairs.

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.
