How To Choose a Window Company in Lake Oswego

Reliability is key when it comes to choosing a window provider. However, your chosen company should also match your priorities and respect your vision. Keep in mind the following factors during your company search:

Window Cost by Type

Replacing your windows is a substantial investment, so balancing cost with durability is important. Although high-quality windows may come with a higher initial price tag, they often yield better long-term value due to their extended lifespan. The age of your home, as well as the sizes, styles, and materials of windows you select, can influence pricing. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. It's recommended to speak with a vetted installer to decide on your ideal options.

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

Window Types Average Cost
Arched $247-$1517
Awning $357-$996
Bay $824-$6114
Custom $366-$1019
Casement $285-$1653
Double-hung $133-$860
Egress $244-$610
Glass Block $48-$618
Picture $214-$1585
Single-hung $96-$1630
Skylight $122-$1472
Sliding $280-$1426
Storm $57-$403
Transom $298-$625

Window Material Cost

Window prices also vary based on material. Each option gives you unique advantages depending on the local climate and energy-saving goals. Fiberglass and vinyl are readily-available materials, so they tend to cost less. Likewise, aluminum and composites look sleek and stay strong against the elements, so they tend to cost more.

Window Types Average Cost
Aluminum $57-$1630
Composite $588-$1322
Fiberglass $96-$824
Vinyl $198-$1834
Wood $294-$1653

Other Window Replacement Costs

Ask each contractor you're considering about labor costs, warranty fees, and permit fees. This will help you get a better picture of the overall expenses involved in the project.

Experience and Training

The longer a window company has served your area, the better its workmanship will likely be. Contact a company representative to learn more about its experience, guarantees, and public and private credentials. Company websites often keep photo galleries where you can see previous work technicians have done.

Licensing and Credentials

In Oregon, window installation is considered "carpentry" and window repair is "handyman services." A company that performs either job will need a permit from the state's Construction Contractors Board. It must also carry a $10,000 surety bond and at least $100,000 in liability coverage.

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. Check a company's website and reviews for any of these types:

  • Awning
  • Bay
  • Bow
  • Casement
  • Crank-out
  • Custom
  • Double- or single-hung
  • Egress
  • Garden
  • Jalousie
  • Picture
  • Sliding
  • Skylight
  • Specialty
  • Storm
  • Transom
  • Vent
Also, check the type of window framing materials a company works with. Each material has varying price points, life spans, and energy performance capabilities. Common materials include aluminum, composite, wood, vinyl and fiberglass.

Customer Feedback

Perhaps the best way to vet window companies for your job is to read what previous customers have said about them. Trustworthy sources for customer reviews include Google, Trustpilot, and Yelp 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 Lake Oswego

How much energy and money will I save by upgrading my windows?

In Lake Oswego specifically, most homeowners using efficient windows reduce their carbon emissions by 270 pounds every year. That amounts to $400 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 purchasing new, more efficient windows, you can improve your home's energy efficiency and reduce your electricity bills.

I've heard there are tax credits for energy-efficient windows. How much could I save?

Ultimately, the tax incentives you can claim are determined by the scope of your window replacement and your city. You can claim up to 30% of the value of new efficient windows as a federal tax credit, up to $3,200 per year, until 2032. We also encourage you to speak with your local utility for more information on financial benefits specific to your area.

How can I gauge the quality of a replacement window?

One of the first metrics you'll notice when looking at a replacement window is its U-factor. The lower this number, the better the window is at blocking extreme heat and cold from entering your home. Other numbers to look at include:
  • "visible transmittance," which measures how much light enters through the window
  • "solar heat gain coefficient," which measures how much UV light the window absorbs and releases as heat
  • "Condensation resistance," which shows how well a window can resist moisture (the higher the number, the better)
  • "Air leakage," which evaluates how easy it is for air drafts to occur (the lower the number, the better)
