How To Choose a Window Company in Lancaster

Each window provider has different offerings and approaches. To streamline 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. Although high-quality replacement windows may cost more upfront, they often provide better long-term value due to their longer lifespan. The age of your home, together with the styles, sizes, and materials of windows you choose, can affect pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while new skylights cost more to prepare for and install. A professional can guide you through selecting the products that fit your needs.

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

Window TypesAverage Cost
Glass Block$48-$608

Window Material Cost

Materials also help determine a window's cost. You might select a material based on the local climate, your desired look, and your energy efficiency goals. 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 TypesAverage Cost

Other Window Replacement Costs

Ask each contractor you're evaluating about warranty fees, labor costs, and permit fees. This will help you get a better picture of the financial commitment involved in the project.

Experience and Training

The longer a window provider has served your area, 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 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 earn a Home Improvement Contractor License by passing exams and sustainability audits.

Types of Windows Offered

The type of window you prefer should factor into your company choice. Not every contractor will necessarily be familiar with the window styles you want. A company website will tell more about the window types it focuses on, such as:

Finally, pay close attention to the materials that a provider uses. Each window frame material has a different energy efficiency level, life span and price point. A company will usually specify whether the windows they mount use metal, fiberglass, wood, vinyl, or composite.

Customer Feedback

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

In Lancaster specifically, most homeowners using efficient windows cut their carbon emissions by 65 pounds each year. This means they save $370 on their annual electricity costs.

The U.S. Department of Energy states that 25%–30% of a home's heating and cooling capacity is used to compensate for heat gain and heat loss through windows. By installing new, more efficient windows, you can enhance your home's energy efficiency and minimize your electricity bills.

Does window replacement involve pulling permits?

Whether you need a building permit to replace your windows depends on your local building codes and regulations. Some cities require permits for window replacement projects, especially those involving structural changes or alterations to the window openings. We recommend checking with your local building department or contact a professional before undertaking any window replacement work.

What's different between a new construction window and a replacement window?

Replacement windows, also known as retrofit windows, are created for properties that already have existing windows. They fit into place 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 intended for installing in a newly built home or during a significant renovation project. These windows feature a nailing fin, which is a thin piece 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.
