How To Choose a Window Company in Charleston

Dependability is essential when it comes to choosing a window replacement company. However, your chosen company should also suit your needs and respect your vision. Think about the following factors during your company search:

Window Cost by Type

When it comes to upgrading your windows, cost-effectiveness is king. Each window you purchase should provide unparalleled durability at a fair price point. Although premium replacement windows may be more expensive to buy, they often yield better long-term value due to their extended lifespan. The size, material, and style of your new windows play the largest role in determining your final cost. Single-hung windows often cost less due to their straightforward style and simple mechanisms, while new skylights cost more to prepare for and install. If you're unsure, a window company can help you decide which options are ideal 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 TypesAverage Cost
Arched$219-$1348
Awning$318-$885
Bay$732-$5436
Custom$326-$906
Casement$253-$1469
Double-hung$118-$765
Egress$217-$542
Glass Block$43-$550
Picture$190-$1409
Single-hung$86-$1449
Skylight$108-$1308
Sliding$249-$1268
Storm$51-$358
Transom$265-$555

Window Material Cost

Replacement window prices also vary based on material. Each option provides different benefits depending on your climate and energy-saving goals. Fiberglass and vinyl 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.

Window TypesAverage Cost
Aluminum$51-$1449
Composite$523-$1175
Fiberglass$86-$732
Vinyl$176-$1630
Wood$261-$1469

Other Window Replacement Costs

Ask each window installer you're evaluating 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

The longer a window company has served your area, the better its workmanship will likely be. Call a company representative to learn more about its public and private credentials, guarantees, and experience. Company websites often have photo galleries where you can see previous work technicians have done.

Licensing and Credentials

South Carolina window installers must carry a Residential Builder license to take jobs costing $5,000 or more. The application process involves trade exams to test an installer's proficiency of state codes and best practices.

Types of Windows Offered

There are a variety of replacement window types you can choose from, and it's vital to find a company that focuses on installing the ones you want. Browse a company's website and reviews for any of these types:

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, aluminum, composite, or wood.

Customer Feedback

One of the greatest ways to evaluate a company is to read what other customers have written about their experiences. Read customer reviews on sites such as Yelp, Trustpilot, and Google. 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 Charleston

How much energy and money will I save by upgrading my windows?

Charleston homeowners could save up to $340 per year by upgrading to efficient windows. They'll also decrease their property's carbon dioxide emissions by 360 pounds per year.

According to the national Department of Energy, as much as 33% of a house's HVAC usage is to compensate for the heat or cold entering through windows. 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?

The answer to this question will depend on your local building codes and regulations. Some towns 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.

How long does a window replacement job take?

The length of a window replacement project can vary greatly. It usually takes up to a month for the contractor to receive your windows from the manufacturer. The installation process itself often takes around an hour per window. However, larger windows or more complex installations may require additional time.
