How To Choose a Window Company in Cottage Lake

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

Window Cost by Type

When you're shopping for replacement windows, it's crucial 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 raise your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The overall cost of your replacement windows will hinge on the specific sizes, materials, and styles you need. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. If you're unsure, a window specialist can help you determine which options are ideal for your home.

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 often choose a material based on aesthetic preferences, the local climate and energy efficiency objectives. 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 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$57-$1,605
Composite$579-$1,302
Fiberglass$95-$811
Vinyl$195-$1,805
Wood$290-$1,627

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 factor in the cost of installation, guarantees, and any other supplemental fees that your project may entail.

Experience and Training

Choose a provider that focuses on window replacement and repair, and look for this information on its website:

  • How long it's been serving the Cottage Lake area
  • Photo galleries of completed projects
  • Private certificates attesting to its workmanship
The more experience a company has, the better its service and workmanship.

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 carry at least one of these license classifications:

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

Types of Windows Offered

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

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

Customer Feedback

Reading other customers' stories is a surefire way to screen window companies in your area. Read customer reviews on sites such as Trustpilot, Yelp, and Google. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. Ask people you know who have used the company you're interested in, and ask a representative for professional references.
