How To Choose a Window Company in Claremont

Dependability is crucial when it comes to choosing a window replacement company. However, your chosen company should also suit your needs and respect your vision. Consider the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with quality is crucial. Choosing cheap windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The material, size, and style of your new windows play the largest role in determining your final cost. Simple double-hung windows deliver great value with their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're unsure, a window provider can help you figure out which options are ideal for your home.

This table shows average prices for various window types to give you an idea of what to expect.

Window TypesAverage Cost
Arched$243-$1495
Awning$352-$981
Bay$812-$6025
Custom$361-$1004
Casement$281-$1629
Double-hung$131-$848
Egress$241-$601
Glass Block$48-$609
Picture$211-$1562
Single-hung$95-$1606
Skylight$120-$1450
Sliding$276-$1405
Storm$57-$397
Transom$294-$615

Window Material Cost

You'll also need to choose a window material. Homeowners often base their decision on aesthetic preferences, energy efficiency objectives and the local climate. 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 wear and warping. Vinyl is readily available and tends to cost less, but don't underestimate its strong durability and low maintenance needs.

Window TypesAverage Cost
Aluminum$57-$1606
Composite$580-$1303
Fiberglass$95-$812
Vinyl$195-$1807
Wood$290-$1629

Other Window Replacement Costs

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

Experience and Training

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

Licensing and Credentials

A California window business must be licensed as a Window Coverings Contractor, Glazing Contractor and General Building Contractor if it performs jobs valued at over $500. Each certification has its own exam and experience requirements. If a contractor is caught working without a license, they'll have to pay steep fines.

Types of Windows Offered

There are several replacement window types you can choose from, and it's crucial to find a company that is experienced with the ones you want. Browse a company's website and reviews for any of these types:

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

Customer Feedback

One of the most surefire ways to screen a company is to check what other customers have written about their experiences. Trustworthy sources for customer reviews include Yelp, Google, and Trustpilot 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 Claremont

How could new windows help my energy efficiency?

In Claremont specifically, most homeowners using efficient windows cut their carbon emissions by 120 pounds every year. That amounts to $510 of annual savings.

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 enhance your home's energy efficiency and reduce your electricity bills.

What should I do if a window is molding or has rot?

Rot tend to set in due to moisture issues or water damage. Fortunately, you may not need to replace your windows to solve this annoying and unsightly issue. A window company can eliminate the mold, restore the affected area, and reset the tight seal your windows need to work at their healthiest.

How do replacement windows differ from new construction windows?

Replacement windows, also known as retrofit windows, are tailored for homes that already have existing windows. They are installed in the existing window opening, without the need to remove or alter the surrounding materials or structure. New construction windows, on the other hand are designed for placing in a newly built home or during a significant renovation project. These windows come with a nailing fin, which is a thin piece of metal or vinyl that protrudes from the frame. It's needed to attach the window directly to the framing of the house, providing a secure fit.
