How To Choose a Window Company in Mercer Island
It's essential to find a window replacement company that matches your specific values, needs, and preferences. Consider the following areas during your search:
Window Cost by Type
When you're shopping for new windows, it's important to remember that there's more to cost than just purchase price. You want a high-quality and durable window. Choosing economy replacement windows could actually raise your overall cost, due to their shorter lifespan and more intensive maintenance needs. The style, material, and size of your replacement 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 a sweeping, custom-size picture window will cost more. It's wise to speak with a trusted window installer to determine your most suitable options.
This table shows average prices for various window types to give you an idea of what to expect.
| Window Types | Average 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
Materials also help determine a window's cost. You might select a material based on the local climate, your energy efficiency goals, and your desired look. For example, wood windows can give your home an organic design without breaking the bank, but you'll have to invest more toward maintenance. Aluminum and composite windows cost more up-front, but they're incredibly durable against the elements, so you'll spend far less on maintenance.
| Window Types | Average 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 applicable warranty fees, permit-related costs (if required), and labor. Ensure that you discuss each of these factors 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 have photo galleries where you can see previous work technicians have done.
Licensing and Credentials
The Washington state government requires every contractor and subcontractor to register with the state Department of Labor and Industries, no matter their income or specialty. A window installer should carry at least one of these license classifications:
- Millwork
- Glass and glazing
- Handyman
- Window coverings
Types of Windows Offered
No two window contractors offer the same window types and materials. Find one that focuses on 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 fiberglass, aluminum, wood, composite, or vinyl.Customer Feedback
Reading other customers' stories is a surefire way to screen window companies in your area. Trustworthy sources for customer reviews include Google, the BBB, and Yelp Speak with people you know who have used the company you're evaluating, and ask a representative for professional references.
Frequently Asked Questions about Window Replacement in Mercer Island
Replacing your windows is a significant expense that greatly impacts your home's livability and energy performance. Hiring a skilled window installer to supervise your project ensures your windows will be properly installed, operate effectively, and be properly insulated. Companies also typically include a warranty that covers required maintenance and most needed fixes.
Windows don't last forever, and most wood models are designed to serve your home for around two decades. Over time, weatherproofing materials weaken, framing contracts and expands, and window coatings fade. These changes result in energy loss, condensation, air leaks, and other expensive problems necessitating repair or replacement.
Whether a company can sell and install blinds ultimately depends on your state's licensing requirements and the company's own preferences. Many jurisdictions require window covering installers to get a unique license, and not every professional will carry one. If you'd like blinds with your new windows, inquire with a company representative if its crews can handle the measuring, cutting, and mounting. If a company can't work with blinds, they could refer you to another company or subcontract the work.
