Key Takeaways

• 391 Aluminum & Vinyl installs replacement windows and doors using aluminum and vinyl frames, the two materials most common in South Carolina homes.
• As a local South Carolina contractor, they handle measurement, ordering, and installation directly rather than routing work through a national company.

• Aluminum and vinyl frames have different costs, durability, and maintenance needs—understanding these differences helps you decide what to ask about when you call.

Aluminum versus vinyl frames: what the difference means for your home

Aluminum frames are lighter and thinner than vinyl, which means they take up less space around the glass and let in more light. They are also stronger and can support larger panes. The trade-off is that aluminum conducts heat and cold, so windows with aluminum frames alone are less energy-efficient than vinyl. Most modern aluminum windows have a thermal break—a plastic or rubber strip inside the frame that slows heat transfer—but they still typically perform worse than vinyl in cold climates.

Vinyl frames do not conduct heat the way aluminum does, so they hold temperature better and lower your heating and cooling costs. Vinyl is also less expensive than aluminum and requires almost no maintenance—you wash it like you would any window. The downside is that vinyl frames are thicker, which means slightly less glass area, and they can warp or become brittle in extreme heat or cold over many decades. In South Carolina's humid subtropical climate, vinyl performs well and is the more common choice for replacement windows.

Neither material rusts or rots the way wood does. Both are durable enough to last 20 to 30 years with normal care. Your choice often comes down to budget, the look you prefer, and how much light you want in each opening.

What to ask 391 Aluminum & Vinyl when you request an estimate

When you contact the company for a quote, have your window measurements ready or be prepared to schedule a time for them to measure your home. Ask whether they provide the windows themselves or if you order them separately. Find out what the estimate includes—labor, installation, removal of old windows, disposal, and any weatherproofing or caulking around the frame.

Ask about the warranty. Most window manufacturers cover defects in the frame and glass for 10 years; some offer longer coverage. The contractor's labor warranty is separate and typically covers installation quality for one to five years. Confirm which warranty applies and what it covers before you sign. If you are choosing between aluminum and vinyl, ask the contractor which material they recommend for your specific windows and why. A contractor familiar with South Carolina homes can tell you which choice makes sense for your climate zone, sun exposure, and budget.

How window replacement typically works with a local contractor

Once you accept an estimate, the contractor orders your windows based on the measurements they took. Lead times vary—some windows ship in two to four weeks, others take longer depending on the manufacturer and current demand. The company should tell you the expected delivery date when you place the order.

On installation day, the crew removes your old windows, prepares the openings, and installs the new frames. They seal around the frame with caulk or foam to prevent air and water leaks. The whole process for a typical home takes one to three days depending on how many windows you are replacing. After installation, the contractor should walk you through operation and care—how to clean the frames, adjust the sashes if they are operable, and what to do if you notice any issues.

Comparing 391 Aluminum & Vinyl to other South Carolina window contractors

South Carolina has many window contractors, from local companies to national franchises. Local contractors like 391 Aluminum & Vinyl often have lower overhead and can be more flexible with scheduling. National chains sometimes offer more standardized pricing and warranties backed by corporate support. Neither approach is inherently better—it depends on your priorities and what you find when you get estimates.

Get at least two or three estimates before deciding. Each should be in writing and include the window model, frame material, labor cost, and warranty terms. Ask each contractor for references from recent jobs in your area. A contractor willing to share names of neighbors who had work done is usually confident in their work.

Frequently Asked Questions

Do I need to replace all my windows at once, or can I do a few at a time?

You can replace windows gradually. Some homeowners prioritize windows that leak or are hardest to operate, then replace others over time as budget allows. A contractor can give you an estimate for any number of windows. Replacing them all at once usually costs less per window because the crew is already set up, but spreading the work out is a valid choice.

What is the difference between a single-hung and double-hung window?

A single-hung window has one sash (the moving part) that slides up and down; the top is fixed. A double-hung window has two sashes that both move. Double-hung windows are easier to clean because you can tilt the sashes inward, and they offer more ventilation options. They also cost more. Ask your contractor which style makes sense for each room in your home.

Will new windows lower my energy bills?

New windows are more energy-efficient than old single-pane windows, especially if your current windows are original to an older home. How much you save depends on your current windows, the new window's energy rating, your climate, and how much you heat and cool. South Carolina's mild winters mean energy savings are usually modest compared to northern states, but they add up over time.

How do I know if a contractor is licensed and insured?

Ask for the contractor's license number and insurance certificate before work begins. You can verify a South Carolina contractor's license through the South Carolina Department of Labor, Licensing and Regulation. Insurance protects you if someone is injured on your property or if damage occurs during installation. Never hire a contractor who cannot provide proof of both.

What should I do if I notice a problem after installation?

Contact the contractor within the warranty period—usually within 30 days for obvious issues. Document the problem with photos and describe exactly what you see. Most contractors will return to fix installation problems at no charge during the warranty period. If the issue is with the window itself rather than installation, the manufacturer's warranty applies.
