How To Choose a Window Company in Greenwich

An exceptional reputation is important when it comes to choosing a window installer. However, your chosen company should also align with your needs and appreciate your vision. Think about the following factors during your company search:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with long life is crucial. Although top-of-the-line windows may cost more upfront, they often yield better long-term value due to their increased lifespan. The total cost of your window replacement will hinge on the specific styles, materials, and sizes you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a custom-cut arch window in a master suite will cost more. An expert can help you with picking the products that fit your preferences.

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

Window Types Average Cost
Arched $238-$1464
Awning $345-$961
Bay $795-$5899
Custom $353-$983
Casement $275-$1595
Double-hung $128-$830
Egress $235-$589
Glass Block $47-$596
Picture $207-$1529
Single-hung $93-$1573
Skylight $117-$1420
Sliding $270-$1376
Storm $55-$388
Transom $288-$603

Window Material Cost

Window prices also vary based on material. Each option provides different benefits depending on the local climate and energy efficiency needs. 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 $55-$1573
Composite $568-$1276
Fiberglass $93-$795
Vinyl $191-$1769
Wood $284-$1595

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 take into account the cost of installation, warranties, and any other supplemental fees that your project may entail.

Experience and Training

Examine a company's website and talk to a representative to learn more about its product and service offerings, pricing, and guarantees. Many companies also keep online galleries that exhibit past projects.

Ensure that the company focuses on window replacement. The more dedicated instruction its staff has, and the longer it has been in business, the more likely it will provide top-notch service.

Licensing and Credentials

While Connecticut doesn't require contractors to carry licenses, they must still register with the state's Department of Consumer Protection (DCP), and there are still limitations on what jobs they can perform. Most residential window installers are considered "minor contractors" and can only work on single and multi-family houses. If a company performs glasswork, it must have a Glazier license from the DCP.

Types of Windows Offered

There are numerous replacement window types you can choose from, and it's essential to find a company that focuses on installing 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
Equally important to your desired windows' shape is their framing. Ask your window company if it offers the frame material you want, such as fiberglass, vinyl, wood, composite, or aluminum.

Customer Feedback

One of the greatest ways to screen a company is to read what other customers have said about their experiences. Read customer reviews on sites such as Trustpilot, Google, and Yelp. You can also view customer reviews and company ratings on the Better Business Bureau (BBB) website. 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 Greenwich

Why should I hire a professional to install or replace my windows?

Replacing your windows is a substantial investment that greatly impacts your home's comfort and energy efficiency. Hiring a professional window company to supervise your project ensures your windows will be the right size, perform optimally, and be properly insulated. Companies also typically include a warranty that addresses required maintenance and most future repairs.

What time of year should I replace my windows?

There is no "right" time to update your windows, but some seasons might be better than others depending on the local climate and a company's demand. Greenwich experiences average winters, so anytime in the fall, spring, or summer will minimize your home's exposure to the elements.

How can I fix a broken window screen?

Most broken screens are very simple to fix. For small tears, some window companies might offer you a repair kit that use strong adhesive patches. If your installer doesn't include a kit, you can purchase one for about $5–$10 at a hardware store.

You might need to replace your screen for large tears or those along the edges of the window. A window service provider you trust can get the job done without breaking the bank.
