Replacement Windows Installed by a Local Exterior Contractor
Your windows affect comfort, energy bills, curb appeal, security, and noise — not just how much light gets in. When they get drafty, hard to open, or start fogging between the panes, replacing them is one of the most noticeable upgrades you can make. Sands Roofing & Construction installs Wincore replacement windows for homeowners across Columbia, Lexington, Irmo, West Columbia, and Chapin.
We chose Wincore because it gives Midlands homeowners practical choices — energy-efficient glass, durable low-maintenance vinyl frames, and a wide range of styles — without making the decision more complicated than it needs to be. We'll help you compare options in plain English and recommend what actually makes sense for your home.
We bring the same local service, clear communication, and careful installation standards to windows that homeowners already trust us for in roofing, siding, and gutters. Family owned and locally operated, serving the Midlands since 2014. Request your free estimate today.
Why New Windows Matter
You may not need new windows just because they're old. But if several of these sound familiar, replacement is worth a look.
5 Benefits of New Windows
- Lower heating and cooling demand with energy-efficient glass
- Fewer drafts and more even room temperatures
- Quieter interiors with insulated, properly sealed units
- Improved curb appeal and resale value
- Low-maintenance vinyl frames that never need painting
6 Signs It May Be Time to Replace
- Drafts you can feel near closed windows
- Condensation or fogging between the glass panes
- Windows that stick or are hard to open, close, or lock
- Cracked, warped, soft, or damaged frames
- Outside noise that feels louder than it should
- Dated windows hurting your home's appearance from the street
Our 5-Step Window Replacement Process
We keep it simple, clear, and low-pressure from the first call to the final walkthrough.
Free Consultation
We talk through what you're noticing with your current windows and what you want to improve — comfort, efficiency, appearance, or resale value — then give you a clear, no-pressure estimate.
Window Assessment
We measure your openings and inspect the trim, frames, and surrounding areas for moisture damage or past installation problems that need to be addressed.
Product Selection
We walk you through Wincore window styles, colors, grid patterns, and glass packages so you can choose the right fit for your home and budget.
Professional Installation
Our crew removes the old windows, prepares each opening, and installs the new units — paying close attention to flashing, sealing, insulation, and trim for a weather-tight finish.
Final Walkthrough
We inspect the finished work with you, show you how each window operates, clean up the jobsite, and make sure you know how to activate your warranty.

Window Styles & Options We Install
We help you choose Wincore window styles that match your home's design and the way you actually use each room.
Double-Hung & Single-Hung
The most popular choice for SC homes. Double-hung sashes tilt in for easy cleaning, while single-hung offers the same classic look at a lower price point.
Sliders
Glide horizontally instead of up and down — a clean, low-profile option that's ideal for wider openings and rooms where a sash swing isn't practical.
Casement & Picture
Casement windows crank open for maximum airflow and a tight seal. Fixed picture windows maximize light and views with excellent energy performance.
Bay, Bow & Geometric
Add architectural character and extra light. Bay and bow windows create depth and seating space, while geometric shapes finish off gables and entryways.
Impact-Resistant Options
For homeowners who want added protection from wind-borne debris during storm season, Wincore offers impact-resistant glass packages on select styles.
Colors, Grids & Glass
Choose from a range of frame colors, grid patterns, and glass packages — including Low-E and argon-filled units — to match your home inside and out.
Built for South Carolina Homes
Midlands homes deal with heat, humidity, heavy rain, strong sun, and seasonal storms. Wincore's energy-efficient glass options — including Low-E coatings and argon-filled insulating units — help reduce unwanted heat gain in summer and hold warmth in winter. Wincore participates in NFRC performance labeling, and many products can be ordered to meet ENERGY STAR guidelines.
Installation is what makes it last. Even a great window underperforms if it's installed poorly. We look at the full exterior system around the opening — flashing, sealing, insulation, trim, and the siding connection — so the finished project looks right and keeps water and drafts out for the long haul.
That whole-exterior focus is the same approach we bring to every roofing, siding, and gutter project across the Midlands.
Warranty Protection You Can Count On
Wincore backs its replacement windows with a comprehensive Lifetime Limited Warranty when properly activated within 30 days of installation. We'll hand you everything you need to register yours so the coverage is locked in from day one.
On top of the manufacturer's warranty, our own workmanship guarantee covers the installation itself — if an issue ever traces back to how we installed your windows, we come back and make it right. Visit our warranty information page for complete details.
