How To Choose a Window Company in Lancaster

It's important to find a window company that matches your specific values, needs, and preferences. Consider the following traits during your hunt:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with value is vital. Although high-quality windows may cost more upfront, they often provide better long-term value due to their longer lifespan. The overall cost of your window replacement will hinge on the particular styles, sizes, and materials you need. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while a sweeping, custom-size picture window will cost more. An expert can help you with picking the solutions 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 TypesAverage Cost
Glass Block$46-$583

Window Material Cost

Window prices also vary based on material. Each option provides different benefits depending on the local climate and energy-saving goals. Vinyl and fiberglass are readily-available materials, so they tend to cost less. Likewise, composites and aluminum look sleek and stay strong against the elements, so they tend to cost more.

Other Window Replacement Costs

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

Experience and Training

Select a business that focuses on window installation and repair, and look for this information on its website:

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

Licensing and Credentials

While Pennsylvania window installers don't need a state license, they must still register with the attorney general's office and follow written contract requirements for residential jobs over $500 in value. Some cities, including Philadelphia, require licensure and have liability insurance minimums.

Types of Windows Offered

No two installers offer the same window designs and materials. Find one that specializes in the type you want for your home.

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

Customer Feedback

Reading other customers' stories is a great way to screen different window companies. You can find customer reviews on websites like Yelp, Google, the BBB, and Trustpilot. 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 Lancaster

What are the benefits of hiring a window installer?

By hiring a professional, you don't need to worry about making measurement mistakes or not having the right tools. A window installation crew is well-equipped with the right supplies and skills to do the job safely and accurately. You can also get fast, informed answers to your questions and tailored assistance to make the most of your new windows

When's the best time to replace my windows?

Window replacement can occur year-round. However, the installation process may be different based on the season. Costs are often cheaper in winter when demand is reduced. Keep in mind, however, that this could overexpose your home to the elements. Discuss with a licensed window professional to determine the best climate conditions for your replacement project.

How can I fix a broken window screen?

It depends on the size of the tear and its location on your window. You can usually repair small tears yourself using a special kit. Some window providers will supply you with one when they set up your windows, or you can buy one for $5–10 from a home improvement store. Larger tears, or those located at the edge of a window, usually need professional assistance.
