How To Choose a Window Company in Mount Pleasant

It's important to find a window installer that matches your individual values, needs, and preferences. Consider the following areas during your search:

Window Cost by Type

Replacing your windows is a major investment, so balancing cost with durability is vital. Choosing economy windows could actually increase your overall cost, since they come with a shorter lifespan and more intensive maintenance needs. The age of your home, as well as the sizes, styles, and materials of replacement windows you choose, can influence pricing. Transom windows are inexpensive with their simple size and straightforward form factor, while a sweeping, custom-size picture window will cost more. If you're unsure, a window company can help you figure out which options are best for your home.

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$43-$550

Window Material Cost

You'll also need to pick a window material. Homeowners often make their selection by considering energy efficiency objectives, the local climate 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 TypesAverage Cost

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 factor in the cost of installation, warranties, and any other extra expenses that your project may entail.

Experience and Training

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

  • How many years it's been operating
  • Photo galleries of projects its crews completed
  • Privately-issued credentials attesting to its workmanship
The more experience a company has, the better its service and workmanship.

Licensing and Credentials

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

Types of Windows Offered

No two window companies offer the same window styles and materials. Find one that's an expert in the type you want for your home.

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

Customer Feedback

Reading other customers' stories is a surefire way to screen window companies in your area. You can find customer reviews on websites like Google, Yelp, Trustpilot, and the BBB. Speak with people you know who have used the company you're evaluating, and ask a representative for professional references.

Frequently Asked Questions About Window Replacement in Mount Pleasant

What are the benefits of hiring a window installer?

Replacing your windows is a big purchase that greatly impacts your home's comfort and energy performance. Hiring a skilled window installer to oversee your project ensures your windows will be properly installed, perform optimally, and be properly insulated. Companies also typically include a warranty that addresses required maintenance and most needed fixes.

Does window replacement involve pulling permits?

The answer to this question will depend on your local building codes and regulations. Some jurisdictions require permits for window replacement projects, especially those that involve structural changes or alterations to the window openings. Generally speaking, it is a good idea to check with your local building department or contact a professional before undertaking any window replacement work.

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 address small tears yourself using a special kit. Some window providers will supply you with one when they set up your windows, or you can get one for $5–10 from a home improvement store. Larger tears, or those located at the edge of a window, usually need professional repair.
