Replacement windows can protect your home from drafts and moisture problems, increase its energy efficiency, and provide it with additional aesthetic appeal. If your windows are getting old or damaged, it's likely time to get new ones. Hiring a licensed window company will help you get the best results and help you avoid costly mistakes from attempting to handle the job yourself.

How To Choose a Window Company in Kenmore

Each window installer has unique offerings and approaches. To ease the company search, keep these factors in mind:

Window Cost by Type

Replacing your windows is a substantial expense, so balancing cost with durability is important. Choosing budget windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The age of your home, together with the styles, sizes, and materials of replacement windows you select, can affect pricing. 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. A window expert can help you with selecting the solutions that fit your needs.

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

Window TypesAverage Cost
Arched$243-$1,493
Awning$352-$981
Bay$811-$6,018
Custom$361-$1,003
Casement$281-$1,627
Double-hung$131-$847
Egress$241-$601
Glass Block$48-$609
Picture$211-$1,560
Single-hung$95-$1,605
Skylight$120-$1,449
Sliding$276-$1,404
Storm$57-$397
Transom$294-$615

Window Material Cost

You'll also need to select a window material. Homeowners usually choose a material based on the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. Wood windows cost less 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-$1,605
Composite$579-$1,302
Fiberglass$95-$811
Vinyl$195-$1,805
Wood$290-$1,627

Other Window Replacement Costs

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

Experience and Training

The longer a window company has been operating, 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

The Washington state government requires all home contractors and subcontractors to register with the state Department of Labor and Industries, no matter their income or trade. A window installer should have at least one of these license classifications:

  • Millwork
  • Glass and glazing
  • Handyman
  • Window coverings
Window installers must also carry a minimum surety bond and liability insurance coverage.

Types of Windows Offered

There are many replacement window types you can choose from, and it's vital to find a company that focuses on installing the ones you want. Search a company's website and reviews for any of these types:

Equally important to your desired windows' shape is their framing. Ask your window installer if it offers the frame material you want, such as wood, aluminum, composite, fiberglass, or vinyl.

Customer Feedback

One of the greatest ways to screen a company is to read what other customers have written about their experiences. Trustworthy sources for customer reviews include Yelp, the BBB, and Trustpilot Speak with people you know who have used the professional you're thinking of hiring, and ask a representative for professional references.
