Installation Standards — How We Build Decks That Last
At Witter Construction, we believe a great deck is more than just boards and rails—it’s a carefully engineered system built to last. Every project is guided by proven construction standards, thoughtful planning, and attention to detail, ensuring your deck is safe, comfortable, and beautiful for years to come.
Built Beyond Code
We exceed building codes, focusing on long-term performance.
Decks are designed to handle real-world use: furniture, gatherings, kids, and pets.
Structural integrity, comfort underfoot, and safety are always our top priorities
structural framing standards
Posts: Minimum 4×6 posts for decks below 4’ above grade, 6x6 posts for anything higher. Composite railing gets 4×4 cedar posts integrated into the frame for extra strength.
Beams: Minimum Doubled 2×8, sized for load support.
Joists & Subframe: Proper spacing for minimal flex, long-term durability.
Fastening: all framing connections are fastened with galvanized framing nails for sheer strength & composite deck screws to pull everything tight and square.
Each framing element is measured and installed for maximum stability and lifespan.
Ground Preparation & Longevity Standards
Proper ground preparation supports long-term performance, drainage, and a clean under-deck appearance.
Weed Barrier: Heavy-duty plastic barrier installed beneath the deck to reduce weed growth and maintenance.
Gravel Base: 6A washed stone applied over the barrier to improve drainage, airflow, and provide a stable, long-lasting foundation.
Landscape Perimeter: 4×4 timber perimeter installed to contain gravel and define the under-deck area. Included with gravel systems unless skirting or fascia extends to grade.
Installation Note: Recommended for elevated decks, low-clearance decks, and walkout basements to enhance durability, drainage, and aesthetics.
Decking Installation Standards
Composite and PVC decking perform best when installed with precision and consistency. As a Platinum-level TimberTech Pro, we follow manufacturer-recommended installation methods and use specialized tools designed specifically for composite / pvc decking to ensure long-term performance and a clean, uniform finish.
Our decking standards include:
Consistent board spacing maintained using manufacturer-approved spacing tools and fastener systems, allowing for proper expansion and contraction
Hidden fastening systems, including CAMO tools where appropriate, for secure attachment and a seamless surface with no exposed screws
Purpose-built installation tools that improve alignment, speed, and accuracy—reducing variability and ensuring consistent results across the entire deck
Intentional board layout and seam planning to create balanced sightlines and minimize visual breaks
Attention to drainage and airflow beneath the deck surface to support durability and long-term performance
By combining proven installation techniques with professional-grade tools, we’re able to deliver a deck surface that feels solid underfoot, looks clean and refined, and continues to perform as intended for years to come.
Stair Construction Standards
Stringers constructed from 2x12 treated Southern Pine, set no wider than 12” on center for sturdy, quiet stairs.
Stairs built to reduce flex, noise, and uneven wear over time.
Consistent rise and run for a comfortable, safe step.
Railing installation standards
Composite railing: 4×4 cedar posts integrated into frame, sleeves installed over structural core.
TimberTech IRX aluminum: Surface-mounted posts, multiple infill options, clean sightlines.
Westbury Tuscany & Veranda: Surface-mounted posts; baluster or glass infill options; mix-and-match layouts supported.
Viewrail Glass: Minimal-frame design; surface-mounted posts; unobstructed views.
Certified Expertise: We are Platinum-Level TimberTech Pros (the highest certification available) and Westbury Pro Certified, meaning our team is trained and approved to install each system according to the manufacturer’s highest standards. This ensures your railings are installed correctly, safely, and built to last.
All railings are installed to maintain rigidity, long-term safety, and visual alignment.
lighting installation standards
When lighting is included in a project, it’s planned and installed as part of the build—not an afterthought.
Our lighting standards include:
Low-voltage lighting systems powered by a single transformer that plugs into a standard exterior outlet
Professional in-house installation—we handle layout, wiring, and setup
Clean wire routing planned during construction for a finished look
Optional wiring protection upgrades available for added durability and longevity
Finish & Craftsmanship Details
Details matter. The difference between a deck that looks good today and one that still looks good years from now is in the finishing work.
Our craftsmanship standards include:
Consistent fastener placement and spacing
Clean, smooth transitions between materials
Straight, aligned posts and railings
Balanced layouts that prioritize symmetry and visual flow
Every element is measured, adjusted, and installed with care.
jobsite care & protection
We treat your home and property with the same care we would our own throughout the construction process.
Our team takes intentional steps to protect your space, including:
Protecting landscaping, lawn areas, and surrounding features
Maintaining an organized, clean jobsite from start to finish
Minimizing disruption to your daily routine whenever possible
When larger equipment is required, laying out a designated access path to protect grass, landscaping, and soil from equipment tracks
Planning material staging and equipment movement to reduce impact on your property
Professionalism doesn’t stop at the finished product—it’s part of the entire experience, from the first day on site to final cleanup..
Documentation & Project Closeout
Every Witter Construction project is completed with the same level of organization and follow-through as the build itself. Final documentation, photography, and warranty registration are handled as part of our standard process, ensuring your project remains accessible and supported long after construction is complete.
Built with Purpose. Installed with Care.
Every standard we follow is intentional—designed to create decks that feel solid, look refined, and perform reliably over time.
