When Your Backyard Becomes Part of the Room
If you've ever stood in your kitchen wishing you could see more of the backyard, or wrestled with a patio door that sticks every time you try to open it, you're not alone. A sliding glass door changes the entire mood of a room, bringing in light, framing the view, and making it easy to step straight outside without a second thought.
Clemmons Windows & Doors installs sliding glass doors for homeowners across Winston-Salem and the surrounding Piedmont Triad, in communities where original patio doors block more of the outdoors than they should. A new sliding glass door reopens that connection, making your backyard, patio, or porch feel like a natural extension of your indoor space.
A Modern Upgrade for Original Openings
Swapping out an old patio door typically means working within the existing opening, not tearing into your walls. Before anything gets installed, we’ll take a close look at your current door, the surrounding framing, and how everything is put together.
That first look tells us plenty. Older sliding doors tend to develop the same handful of problems:
Hardware that's worn down or hard to operate
Drafts around the frame, especially in colder months
Signs of moisture getting in where it shouldn't
A door that's become tough to slide open or closed
Once we know what we're working with, we’ll bring in the new door and set it into place. Getting the alignment and adjustment correct is what separates a door that glides smoothly for years from one that starts sticking again within a season. We’ll also take care with the finishing work around the edges, so the transition between your new door and the rest of your home looks intentional and keeps water and air where they belong.
Premium Materials. Proven Performance.
We settled on ProVia after seeing how their sliding patio doors perform through everything a Piedmont Triad summer and winter can throw at them. The frames are made from virgin vinyl rather than a recycled blend, which helps them keep their shape and appearance through hot summers and cold snaps alike. ProVia's insulated glass units also use low-emissivity coatings that reduce heat transfer without blocking the light you're trying to bring in. For homeowners looking to lower energy costs while opening up their home, that combination goes a long way.
We're also a ProVia Platinum Dealer with certified ProVia installers, which means we've met their standards for training, product knowledge, and customer service. That designation isn't just a badge, but reflects the accountability we bring to every install. A well-made door still depends on the hands installing it, and that's exactly why we take the ProVia certification so seriously.
Style Choices That Complement Your Exterior
Your patio door covers a large section of visible wall, so how it looks carries nearly as much weight as its performance. It's one of the first things you notice pulling into the driveway, and one of the last things you see before heading outside.
ProVia offers a range of frame colors and configurations to complement a variety of home styles, from traditional white and almond tones to bolder finishes that pop. But color is only part of the decision. You'll also want to think through how much glass you want visible, whether you prefer one large panel or a paneled look, and how the hardware finish ties into your other exterior details, like your entry door or light fixtures. Small choices like these add up to a patio door that looks chosen for your home rather than picked off a shelf.
Long-Term Protection for Your Investment
A patio door replacement is an investment, and you deserve to know it's protected long after we've left. ProVia backs its sliding glass doors with coverage that's hard to find elsewhere:
Lifetime Transferable Warranty: Selling your home doesn't cancel this coverage. It transfers to the next owner, which can be a selling point when it comes time to list.
Accidental Breakage Warranty: This warranty covers certain types of accidental damage that many standard warranties require homeowners to pay for out of pocket.
100-Year Labor Warranty: Our labor warranty covers installation specifically, so you're protected on that front, not just by whatever coverage comes from the manufacturer.
Our labor warranty runs alongside ProVia's manufacturer coverage, so you have two layers of protection working together. Whoever owns your home next inherits the same protection you have today, without any extra paperwork or phone calls on your part.
Why Choose Clemmons Windows & Doors?
With so many window and door companies across the Piedmont Triad, it's worth knowing who's going to be in your driveway with tools in hand. At Clemmons Windows & Doors, the people who quote your project are the same people who install it. We don't subcontract out the labor, and we don't hand your project off to whichever crew happens to be free that week. We're locally owned and family-operated, and every project we take on reflects that.
Our crews live in these communities, install in these communities, and stand behind the work long after the job is finished. When you call with a question six months or six years from now, you're talking to people who remember your project, not a call center reading from a script.
Curious what that looks like in practice? Take a look at our customer reviews page to hear directly from homeowners about their experience with Clemmons Windows & Doors.
The Honest Guidance You Deserve
Buying a patio door shouldn't feel like being sold one. We'd rather earn your trust with straightforward advice than a high-pressure pitch.
During your estimate, we'll go over your options and give you our honest take, even if that means recommending a smaller project than what you originally had in mind. If your current door only needs new hardware rather than a full replacement, we'll let you know that too.
Financing is part of that same approach. We offer financing options for qualifying homeowners, including no-interest, no-payment plans for eligible projects, so budget doesn't have to be the reason you put off a project you've been wanting to do.

Winston-Salem
Clemmons

Homes throughout this region were largely built between the 1940s and early 2000s, and their original patio doors are reaching the point where replacement makes more sense than another repair. We’re here to help homeowners in these communities swap a tired sliding door for one that fits right in. Check out our service areas page for the full list of communities we cover.
Frequently Asked Questions
From signing your quote to installation day, plan on about four to six weeks, depending on product availability and your specific project. Timelines may vary, so we'll confirm a firmer estimate once your order is placed.
We install only the doors we provide. That's what lets us stand behind the entire project, from the product itself through installation and warranty support.
That depends on your current setup and what you're hoping to get out of the upgrade. During your consultation, we'll review your existing door and help you decide whether ProVia aligns with your home and goals.
It means the warranty doesn't expire when you sell your home. If you move, the next owner picks up the remaining coverage on the door.
Give Your Home the Door It’s Been Missing
If your current patio door sticks, lets in a draft, or just doesn't match your home anymore, we're here to help you figure out what comes next. We offer virtual consultations, instant quotes for qualifying projects, and free in-home estimates throughout the Piedmont Triad.
