How to Choose a Window Replacement Company Near You That Measures Before It Orders
Choosing a window replacement company near you is mostly about what happens before install day. Replacement windows are built to order, so a bad measurement can't be fixed with extra caulk. Charleston Roofs and Windows puts a project manager on the tape before anything is ordered.
"The sales rep Tommy was delightful to deal with and informative about the replacement windows, not hard sales at all. My installer Sam was knowledgeable and conscientious and all the office staff could not have been more helpful."
Five Questions to Ask Before You Hire a Window Installer
Ask every window company these five questions. Here's how Charleston Roofs and Windows answers each one.
Who Measures My Windows, and When?
A quick tape measure is fine for a quote. A custom window needs the width and height checked at several points, because older openings are rarely square. Ask who takes the final measurements and whether that person is on site for the install.
How Charleston Roofs and Windows Answers
After you approve the estimate, your project manager comes out, reviews the job and measures every opening before the order goes to Viwinco. He's the same person who oversees install day and walks the finished job with you.
Is the Installer Trained by the Window Manufacturer?
Viwinco puts it plainly: windows and doors are only as good as their installation. A well-built window set out of square still leaks air and water. Ask whether the manufacturer recognizes the company as a trained installer.
How Charleston Roofs and Windows Answers
Charleston Roofs and Windows holds Viwinco's Blue Label designation and installs Viwinco windows and patio doors every week.
● Viwinco Blue Label Preferred Installer
Blue Label is Viwinco's program for identifying accredited installers who are trained on its product line and handle the job from measurements through installation and beyond.
● Viwinco Limited Lifetime Warranty
Viwinco's limited lifetime warranty covers the vinyl, insulated glass seal and hardware for the original owner. If you sell, it becomes a 20-year warranty that transfers to the next owner with a transfer form.
What Are Your Impact Windows Tested To?
"Impact" gets used loosely. Ask what the glass is made of and which test the window passed. If the salesperson can't answer, the window may only be tempered glass, which shatters on impact.
How Charleston Roofs and Windows Answers
We install Viwinco OceanView impact windows. Each one pairs a tempered Low-E pane with a laminated pane built around a PVB interlayer, and the line is tested to Missile Level D impact standards.
Who Supervises the Installers?
Many window companies sell the job and hand it to a crew nobody checks. Ask who is responsible while the work goes in.
How Charleston Roofs and Windows Answers
Our installers work under an in-house project manager who knows the trade. He oversees the install from start to finish and does the final walkaround with you before the job closes.
How Long From Order to Install?
Custom windows take time to build. Next-week install on custom sizes usually means stock sizes or guesswork.
How Charleston Roofs and Windows Answers
Expect about three weeks from order to delivery, and one day of installation for most homes. Amanda in our office confirms your delivery and schedules install day around your calendar.
Red Flags When Shopping for Replacement Windows
If half the windows are free, the other half carry the cost.
You should know exactly which window you're paying for.
Energy talk without NFRC ratings is just adjectives.
Ask for the impact standard the window passed.
That's how custom windows arrive the wrong size.
Window and Patio Door Services From Charleston Roofs and Windows
Charleston Roofs and Windows replaces windows and patio doors with Viwinco products built to your exact measurements. Viwinco offers impact and non-impact options, and every job runs under one project manager from measurement to walkaround.
Window Styles We Install
Double Hung Windows
Both sashes slide up and down, so you can vent hot air out the top. Viwinco's patented Tilt-n-Lock lets both sashes tilt in for cleaning from inside.
Single Hung Windows
The bottom sash opens and the top stays fixed. A lower-cost choice that still fits the look of most Lowcountry homes.
Casement Windows
Hinged on one side and cranked open like a door. They catch a cross breeze and press tight against the frame when closed.
Awning Windows
Hinged at the top and opened outward from the bottom. Great above a sink or tub where you want air and privacy.
Sliding Windows
One sash glides sideways along a track. Wide views, no crank, and an easy reach over a counter or bed.
Bay and Bow Windows
Three or more units that project out from the wall. You get more light and a window seat without building an addition.
Picture, Geometric and Custom Colored Windows
Fixed picture windows, arches and custom shapes, plus Viwinco's custom exterior colors with grid and simulated divided lite options.
Hurricane Impact Windows
Viwinco OceanView impact windows with laminated glass that stays in the frame when debris hits. Built for coastal homes that want protection without shutters.
Patio Door Replacement
Viwinco sliding and multi-track patio doors in impact and non-impact glass, matched to your new windows so the whole back of the house looks like one project.
Storm-Damaged Window Replacement
Cracked glass or a frame knocked loose by a storm gets boarded up fast and replaced under the same project manager who handles your roof.
Financing on Every Window Project
Charleston Roofs and Windows offers 0% interest for 12 months on approved credit through Service Finance Company. It covers one window, a whole house of impact windows or a new patio door, with fast credit decisions.
Hurricane Impact Windows Built for Lowcountry Storm Season
A hurricane impact window is a window with laminated glass that cracks but stays in the frame when windborne debris hits it. Charleston Roofs and Windows installs Viwinco OceanView impact windows for homeowners who want storm protection that's always in place.
What Makes a Viwinco OceanView Window Impact Rated
Viwinco built OceanView for coastal homes, and the details matter more than the word "impact" on a brochure.
- 15/16 inch double-strength glass package. Thicker than a standard insulated unit.
- Tempered Low-E pane. Cuts solar heat while adding strength.
- Laminated pane with a PVB interlayer. A tough plastic sheet that holds the glass together if it's struck.
- Missile Level D testing. The impact standard the OceanView line is tested to.
- Tilt-n-Lock on hung windows. Same easy cleaning as the standard lines.
- Quieter rooms. Viwinco lists enhanced sound reduction as an OceanView feature.
Impact Windows vs. Standard Windows and Shutters
| Factor | Standard Insulated Window | Window Plus Storm Shutters | Viwinco Impact Window |
|---|---|---|---|
| When debris hits | Glass breaks and the opening is exposed | Shutter takes the hit if it was installed in time | Glass cracks but stays bonded in the frame |
| Storm prep | Plywood or nothing | Someone has to close every shutter before the storm | Nothing to do, protection is always on |
| Noise | Standard | Standard | Laminated glass dampens outside noise |
| Looks | Clean | Hardware on every opening | Looks like a standard window |
| Upfront cost | Lowest | Middle | Highest per window |
Wind Mitigation Discounts and SC Safe Home Grants
Impact windows can qualify for wind mitigation insurance discounts. SC Safe Home grants also exist for eligible homeowners who strengthen their homes, and Charleston Roofs and Windows can point you to the program details.
Energy Efficient Windows for Lowcountry Heat and Humidity
An energy efficient window is a window whose NFRC-rated U-factor and solar heat gain coefficient meet the ENERGY STAR limits for your climate zone. Ask Charleston Roofs and Windows for both numbers on any window we quote, because here the summer sun is the enemy.
Every ZIP code in Charleston, Berkeley and Dorchester counties falls in the ENERGY STAR South-Central climate zone under Version 7.0. Here's what a window or glass patio door has to hit to earn the label in our zone.
Why SHGC Matters More Than U-Factor Here
Lowcountry homes spend far more on cooling than heating. A low solar heat gain coefficient blocks the sun's heat before it reaches your floors and furniture. On west-facing walls and big sliders, SHGC is the number Charleston Roofs and Windows tells homeowners to watch.
How to Read the NFRC Label
- Find the U-factor first. Lower is better. Look for 0.28 or under.
- Check the SHGC next. Lower is better here. Look for 0.23 or under.
- Look for the ENERGY STAR zone map. The South-Central zone should be marked.
"Our windows are beautiful & very well made. We are very pleased!! Kevin (Sales) & Adam (Manager) were fantastic!!"
The frame decides how a window handles humidity, salt air and the sun for decades. Charleston Roofs and Windows installs Viwinco vinyl windows, and this is how vinyl stacks up against the other frame materials you'll see on quotes.
Why We Install Vinyl in Our Climate
Quality vinyl doesn't rot in humidity, doesn't need paint every few summers, and holds up near salt air. Viwinco's vinyl carries lifetime coverage against peeling, flaking and blistering for the original owner.
Signs You Need Window Replacement and When Repair Is Enough
Window replacement is the right call when the frame, the glass seal or the sash itself has failed, not just a part you can swap. Charleston Roofs and Windows tells you which one you're dealing with before quoting, because some problems don't need a new window.
Seven Signs It's Time to Replace
- Fog or haze between the panes. The insulated glass seal has failed and the gas fill is gone.
- Soft, dark or crumbling sills. Water has been getting into the frame.
- Sashes that stick, drop or won't lock. Common on older aluminum and warped wood.
- Drafts you can feel on a windy day. Air is leaking past worn weatherstripping and frames.
- Single-pane glass. No modern glass package to block heat.
- Faded floors and furniture near the glass. Too much solar heat and UV getting through.
- Cracked glass or bent frames after a storm. A safety issue and an open door for water.
"We are so pleased with our new windows, and I would refer them to anyone!!"
Insert Replacement vs. Full-Frame Replacement
Viwinco replacement windows are built without a nailing flange, so they fit inside your existing frame when that frame is solid.
If the frame has rot or the opening is changing size, a full-frame or new construction window with a nailing flange is the better call. Your project manager confirms which one before ordering.
