Types of window work they handle

McKnight & Son's Glass Co installs new windows in homes undergoing renovation or new construction. This includes measuring the openings, ordering windows to specification, and installing them so they seal properly and operate smoothly. They also replace existing windows—a common project when older windows fail, leak, or no longer insulate well.

The company repairs broken glass, damaged frames, and windows that no longer close or seal. If a single pane cracks or a frame warps, they can often repair it without replacing the entire window. They also do custom glass work, which means they can cut and install glass for unusual shapes, sizes, or applications beyond standard windows.

How to contact McKnight & Son's Glass Co

To get in touch with McKnight & Son's Glass Co, call them directly or visit their location in person. They can answer questions about your specific project, schedule a site visit if needed, and provide a quote based on what you need done. Having details ready—such as the number of windows, their current condition, and your timeline—helps them give you a more accurate estimate.

If you are planning a larger project, such as replacing all the windows in a house or installing windows in a new building, let them know the scope upfront. This helps them schedule the work and order materials efficiently. For smaller repairs or a single window replacement, they may be able to fit you in more quickly.

What to expect during a window installation

When McKnight & Son's Glass Co installs windows, they typically begin by removing the old window (if replacing) and preparing the opening. They measure carefully to ensure the new window fits properly and will seal against weather and air leaks. The window is then installed, leveled, and secured, and any gaps are sealed with caulk or insulation to prevent drafts.

The entire process—from removal to final cleanup—usually takes a few hours per window, though the total time depends on how many windows you are having done and how accessible they are. They clean up debris and old materials when the job is finished. If you are having multiple windows done, they may schedule the work over one or more days depending on the number and location of the windows.

Pricing and what affects the cost

The cost of window installation or repair varies based on several factors: the number of windows, the size and type of windows you choose, whether you are replacing existing windows or installing new ones in an opening, and the condition of the frames and surrounding areas. A single window repair costs far less than replacing ten windows in a house. Energy-efficient windows or custom sizes also affect the price.

The best way to understand the cost for your project is to contact McKnight & Son's Glass Co directly and describe what you need. They can give you a quote after learning the details. Many window projects may have access to for tax credits or rebates if the windows meet energy-efficiency standards, so ask them whether your choices might may have access to.

When to call for repair versus replacement

If a window has a single cracked pane, a broken seal (fogging between panes), or a frame that needs adjustment, repair is often the faster and cheaper option. McKnight & Son's Glass Co can assess whether repair makes sense or whether replacement is the better choice. Sometimes a repair buys you time; sometimes the window is old enough that replacement saves money in the long run.

Replacement makes more sense if multiple windows are failing, if the frames are rotting or severely damaged, or if you want to upgrade to more energy-efficient windows. Replacing all the windows in an older house can lower heating and cooling costs noticeably, especially if the current windows are single-pane or have poor seals. A site visit from McKnight & Son's Glass Co can help you decide which approach fits your situation and budget.

Frequently Asked Questions

Do I need to replace all my windows at once?

No. You can replace windows one at a time or in groups as your budget allows. However, if you are planning to replace most or all of them eventually, doing them together sometimes costs less per window because the contractor can order materials in bulk and schedule the work efficiently. Ask McKnight & Son's Glass Co whether bundling your windows would lower the per-window cost.

How long do new windows last?

Modern windows typically last 20 to 30 years or longer, depending on the material, climate, and how well they are maintained. South Carolina's humidity and occasional storms can affect window lifespan, so proper installation and occasional maintenance matter. McKnight & Son's Glass Co can tell you what to expect from the specific windows you choose.

Can they install windows in an older house?

Yes. Older homes often have window openings that are slightly different sizes or shapes than modern standard windows, but McKnight & Son's Glass Co can measure and fit windows to those openings. They may need to do some frame adjustment or use custom sizing, which they can discuss when they visit your home.

What if a window breaks after installation?

Contact McKnight & Son's Glass Co to report the damage. Most reputable installers stand behind their work and can repair or replace a window that fails due to installation error. If the damage is from an accident or weather event, your homeowner's insurance may cover it. Ask about any warranty that comes with your new windows.

How do I prepare my home for window installation?

Clear the area around each window so the crew has access and space to work. Move furniture, plants, or decorations away from the windows. Let McKnight & Son's Glass Co know if there are obstacles they should be aware of, such as landscaping close to the house or interior walls that are difficult to access. They will let you know if anything needs to be moved before they arrive.
