How To Choose a Window Company in Lancaster

It's crucial to find a window company that meets your specific values, needs, and preferences. Consider the following areas during your search:

Window Cost by Type

When it comes to upgrading your windows, value is most important. Each window you buy should deliver maximum durability at an affordable price point. Choosing budget windows could actually increase your overall cost, due to their reduced lifespan and more intensive maintenance needs. The total cost of your window replacement will hinge on the particular sizes, styles, and materials you need. 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. If you're unsure, a window provider can help you determine which options are most suitable for your home.

In this table, you can find cost data for the most common residential window types to determine how much you might pay.

Window Types Average Cost
Arched $243-$1492
Awning $351-$980
Bay $810-$6014
Custom $360-$1002
Casement $280-$1626
Double-hung $130-$846
Egress $240-$600
Glass Block $48-$608
Picture $211-$1559
Single-hung $95-$1603
Skylight $120-$1447
Sliding $276-$1403
Storm $57-$396
Transom $294-$614

Window Material Cost

You'll also need to pick a window material. Homeowners often make their selection by considering the local climate, energy efficiency objectives and aesthetic preferences. Aluminum windows are perfect for sleek, modern designs, but they cost more up-front. You'll pay less for wood windows 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 Types Average Cost
Aluminum $57-$1603
Composite $579-$1300
Fiberglass $95-$810
Vinyl $195-$1804
Wood $289-$1626

Other Window Replacement Costs

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

Experience and Training

The longer a window installer has been operating, the better its workmanship will likely be. Speak with 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

New York's state government doesn't issue contracting licenses for window installers, but this hasn't stopped local governments from intervening and establishing their own licenses. For example, to install windows in New York City, a company must obtain a Home Improvement Contractor License by passing exams and ecological assessments.

Types of Windows Offered

There are several replacement window types you can choose from, and it's crucial 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
Also, check the kind of window framing materials a company works with. Each material has distinct price points, life spans, and energy performance capabilities. Common materials include composite, vinyl, aluminum, fiberglass and wood.

Customer Feedback

Perhaps the best way to evaluate window companies for your job is to check what previous customers have said about them. You can find customer reviews on websites like Google, Trustpilot, Yelp, and the BBB. 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

How could new windows help my energy efficiency?

Lancaster homeowners could potentially save $370 per year by installing efficient windows. They'll also decrease their property's carbon dioxide emissions by 65 pounds per year.

According to the federal Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. Energy-efficient windows help keep heat out in the summertime and retain heat in the wintertime, improving your comfort and furthering your dollar.

Does window replacement involve pulling permits?

Replacing windows may involve obtaining permits, based on your local building codes and regulations. Some cities mandate permits for window replacement projects in cases involving structural changes or alterations to the window openings. We recommend you check with your local building department or consult a professional before undertaking any window replacement work.

How do replacement windows differ from new construction windows?

Replacement windows, also known as retrofit windows, are specifically designed for homes that already have existing windows. They are placed in the existing window opening, without the need to remove or alter the surrounding materials or structure. New construction windows, on the other hand are designed for mounting in a newly built home or during a significant renovation project. These windows come with a nailing fin, which is a thin strip of metal or vinyl that extends from the frame. It's used to attach the window directly to the framing of the house, ensuring a secure fit.
