314-WINDOWSSt. Louis Deck Builders
Your backyard deserves better than warped boards, splinters, and a deck that embarrasses you every cookout. Whether your old deck is rotting from the inside out or you’re starting from scratch, Strait Windows builds beautiful, low-maintenance outdoor living spaces that last — and add real value to your home.

Sound Familiar?
Most St. Louis homeowners put up with a bad deck for years before doing anything about it. Here’s what we hear every single day.
Soft spots, crumbling posts, wobbly railings — every step feels like a gamble. A deck that’s structurally compromised isn’t just an eyesore, it’s a liability waiting to happen.
Staining, sealing, sanding — every spring you swear you’ll deal with it. Pressure-treated wood demands constant attention, and the moment you skip a year, you pay for it for three more.
Your neighbors upgraded. Buyers notice. A gray, weathered deck drags down the look of your entire home and makes outdoor entertaining something you dread instead of enjoy.
You have the yard for it — the kids, the grill, the evenings outside. You just don’t have a deck that makes any of it worth doing. That lost time is the real cost of waiting.
What We Do
Whether you’re building new or replacing what’s there, our crews handle every phase — so you don’t have to manage multiple contractors.

New Builds
Turn your bare yard into the outdoor living room you’ve always pictured. We design and build custom decks from the ground up — composite, pressure-treated, or hardwood — in any size, shape, or elevation your property calls for.

Tear-Out & Replace
Sometimes a refresh isn’t enough. If your deck’s substructure is compromised, we’ll tear it out completely and give you a fresh start — built right, this time. No patching over problems. No surprises two years later.
Our Process
No confusion, no surprises. Here’s exactly what happens after you reach out to us.
We come to you. One of our project advisors walks your yard, asks questions about how you use your space, and helps you think through materials and layout — zero obligation.
We present a detailed plan with options for materials, colors, and features. Composite vs. wood, railing styles, board direction — you decide exactly what you want before anything is ordered.
We pull every required permit and coordinate the schedule around you. Most homeowners never have to deal with the city — we handle all of it so you can focus on being excited, not stressed.
Our experienced crew shows up on time, works efficiently, and respects your property. We protect your landscaping, clean up daily, and build to last — no shortcuts, no subcontracting the hard parts.
Before we leave, we walk the completed deck with you, answer every question, and make sure you’re 100% happy. Your workmanship warranty starts the day we hand over the keys — or the grill tongs.
Why Strait Windows
We’ve been building and replacing decks in the St. Louis metro for over 20 years. Here’s what makes the difference.
Common Questions
Most standard residential decks — 200 to 500 sq ft — take between 3 and 7 business days from the first nail to the final inspection. Larger or more complex projects (multi-level, pergola additions, custom built-ins) may run 2–3 weeks. We give you a firm timeline before any work begins.
Composite (brands like Trex or TimberTech) costs more upfront but eliminates staining, sealing, and most splinter risk — over a 10- to 15-year span it often costs less. Pressure-treated wood is budget-friendly, takes paint well, and is great for projects where cost is the main driver. We’ll walk you through both options honestly.
Almost certainly yes — most municipalities in St. Louis City and County require a permit for any attached deck or any freestanding deck above a certain height. We handle all permit applications and inspections as part of our standard process. You won’t have to set foot in a municipal office.
Yes. We carry composite decking and railing options in dozens of colors, and we’ll bring samples to your home during the consultation so you can see them next to your siding, trim, and landscaping in real light before you commit.
A basic pressure-treated deck starts around $8,000–$12,000 for a standard-size project. Composite decks typically run $15,000– $30,000+ depending on size and features.
