Your front door is the first thing a guest touches and the last thing standing between your house and a February wind. Getting it right is less about the door than about the install — a beautiful slab hung out of plumb will stick, drift, and leak air within a season. That’s the part we’ve been doing since day one.
314 Window & Door began as the crew St. Louis roofing companies called to handle their openings, and after 1,000+ completed window and door projects, we still do the work ourselves — certified, W-2 crews, no subcontractors. We install entry, patio, and interior doors from ProVia, Therma-Tru, Waudena, Andersen, and Pella, which means we recommend the door that suits your home rather than the one brand we’re contracted to move.
Fiberglass is the workhorse of the St. Louis market, and for good reason — it won’t rot, warp, or rust, it insulates better than steel, and modern grain textures read convincingly as wood. It costs more up front and rewards you with two decades of not thinking about it.
Steel is the value option and the security favorite: strong, affordable, and dimensionally stable. The tradeoff is that dents are permanent and scratches can rust, so a west-facing door with no storm protection may age faster than you’d like.
Wood is unmatched for historic homes and custom millwork, and it asks for refinishing every few years in return. On a covered porch it can last generations; fully exposed to Missouri weather, it needs a committed owner. We’ll tell you honestly which category your opening calls for during the free estimate.

Cost comes down to material, size, and glass. A straightforward steel replacement in an existing opening sits at the affordable end; a fiberglass ProVia or Therma-Tru system with sidelites, decorative glass, and new hardware lands considerably higher. Because we install several brands across several price tiers, we can usually put two or three real options in front of you instead of one number. Estimates are free and itemized, and financing is available through GreenSky and Synchrony.
For most St. Louis homes, fiberglass — it insulates better, never rusts or rots, and holds up to our humidity swings without warping. Steel is the stronger value play and is genuinely tough, but dents are permanent and deep scratches can rust if the door takes weather head-on. If your entry is covered by a porch and budget is the priority, steel makes real sense. We’ll look at the actual exposure during your estimate.
Often, yes — but it depends on the header and the rough opening. Swapping a slider for hinged French doors can require reframing, and the swing needs clearance the slider never did. We measure the opening, check what’s structural, and tell you plainly what the conversion involves before you commit to anything.
Once your door arrives from the manufacturer — typically a few weeks after measurement — most single entry or patio door installs are finished in a day. Your home is never left open overnight. We fit the hardware, finish the trim, test the operation with you, and haul the old door away before we go.
Yes. Interior and closet doors are a smaller job than an exterior system, but the same thing determines whether you’re happy in five years: whether it was hung plumb and square. We handle prehung and slab replacements, and it’s a common add-on when we’re already on site for entry doors or window replacement.
Doors and windows are where the overwhelming majority of water gets into a house. A door set even slightly out of square will drag on the jamb, stress the weather stripping, and let air and moisture past the threshold — and no manufacturer warranty covers a door that failed because of how it was hung.
Our crews are certified by ProVia, Therma-Tru, and OSI, EPA Lead-Safe trained for older St. Louis homes, and they follow manufacturer specs on sill pans, flashing, shimming, and sealing at every opening. Then we back the work with a 1-year labor warranty and service every manufacturer warranty attached to what we sell.
Roofing companies, builders, and multifamily property managers hire us for their door and window work — jobs where one callback costs a contractor a client. You get those same crews on your own front step.
