Thornhill is a community known for its elegant homes, mature neighborhoods, and luxury new builds. From the historic charm of Old Thornhill to the upscale developments in Uplands and Beverley Glen, homeowners expect quality craftsmanship and modern design. At Modern Stairs Plus, we create custom stairs and railings that elevate interiors while maintaining safety, structure, and style.
We offer full-service staircase solutions, including design, fabrication, and installation — all managed in-house for precision and quality control. Whether you’re building a contemporary custom home, renovating a classic two-storey, or adding value to an investment property, our stair systems are built to impress and engineered to last.
With years of experience working in Thornhill, we understand the level of detail, customization, and finish that discerning homeowners demand.
Modern staircases make a statement — and in Thornhill’s luxury homes, that statement matters. We design stairs that flow seamlessly with your home’s architecture and layout, using high-quality materials and clean structural lines.
Our design team provides 3D models and consultations to help you explore floating stairs, open risers, minimal railings, or material blends. Every design is personalized for aesthetics, functionality, and code compliance — whether you’re in a sleek custom build or modernizing a traditional interior.
We bring both creativity and precision to every step of the design process.
A staircase is only as strong and beautiful as its installation. At Modern Stairs Plus, we provide expert interior staircase installation in Thornhill — ensuring every tread, riser, stringer, and railing is perfectly aligned and securely fastened.
We work with homeowners, designers, and builders to install straight stairs, switchback layouts, curved runs, and floating systems. Our team respects your timeline, protects your space, and delivers flawless installation from the first step to the last.
Every stair we install meets or exceeds Ontario Building Code for safety, durability, and design.
Metal railings are a premium choice for homeowners seeking strength, sophistication, and versatility. In Thornhill, we design and fabricate custom metal railing systems that complement modern, transitional, and even classic interiors.
Choose from aluminum, stainless steel, wrought iron, or powder-coated finishes in sleek or decorative styles. Our railings are fabricated in-house and installed on-site, tailored to your stairs, balconies, or walkways for a secure and stylish fit.
Whether inside or out, our metal railings combine form and function at the highest level.
Hardwood staircases bring warmth, texture, and timeless beauty to Thornhill homes. We build custom wood stairs and railings using oak, walnut, maple, ash, and other select hardwoods — all finished to suit your interior style.
From traditional turned spindles and detailed newel posts to modern, square-profile components, we craft stair systems that feel handcrafted and high-end. Whether part of a new build or a renovation, our wood staircases are a lasting investment in style and value.
Each system is measured, fabricated, and installed to perfection.
Glass railings are a must-have in many of Thornhill’s high-end homes. They offer safety without visual interruption — ideal for maximizing light, space, and modern elegance.
We install custom glass railing systems with frameless, semi-frameless, or framed options using tempered safety glass and premium hardware finishes. Perfect for staircases, lofts, balconies, and landings, our glass railings are engineered to meet code while enhancing architectural design.
Pair them with floating stairs or hardwood treads for a refined and open look.
Floating staircases are the centerpiece of modern luxury interiors — and we build them right. In Thornhill, our floating stair systems are found in custom homes where style and structure meet.
We use concealed steel supports, open risers, and high-quality treads in wood or composite finishes. Each system is engineered for strength, stability, and clean lines — giving your staircase the illusion of weightlessness while remaining fully secure and code-compliant.
A floating staircase is more than just a passage — it’s a visual centerpiece.
Thornhill’s modern homes demand railings that match their upscale interior aesthetic. At Modern Stairs Plus, we specialize in contemporary stair railings using slim-profile metals, clear glass, cable systems, and wood accents.
Each system is designed to enhance visibility, complement architectural features, and maintain safety. Whether you’re pairing with floating stairs or upgrading a classic staircase, our contemporary railings deliver sleek results that hold up to daily use.
Our railing designs are minimal, stylish, and built to the highest standards.
Upgrading your staircase can dramatically enhance the appearance and value of your home. At Modern Stairs Plus, we specialize in residential stair renovations in Thornhill — updating worn, outdated, or builder-basic stair systems with premium materials and modern designs.
We can refinish treads, replace railings, update layouts, or completely rebuild your stair system. Whether you’re renovating a classic Thornhill home or refreshing a newly purchased property, we tailor each renovation to match your taste, layout, and budget.
Our team ensures that all upgrades meet building codes while adding refined beauty to your interior.
From office buildings to apartment complexes and retail environments, commercial spaces in Thornhill require safe, durable, and visually appealing stair systems. At Modern Stairs Plus, we provide custom commercial stair and railing solutions that are functional and professionally finished.
Our commercial stairs are constructed in steel, concrete, or engineered wood, with railing systems in metal, glass, or combination materials. Every system is designed to meet Ontario Building Code and AODA accessibility requirements.
We coordinate with developers, contractors, and project managers to ensure seamless integration, efficient timelines, and dependable performance.
Unique homes require custom solutions. At Modern Stairs Plus, we offer in-house stair fabrication services in Thornhill — building one-of-a-kind stair systems tailored to your space and architectural style.
We fabricate stair components including treads, risers, stringers, railings, and posts using CNC technology and premium materials. Whether your design calls for a curved staircase, a tight corner run, or a sculptural floating stair, we build it to exact specifications for a flawless result.
Custom fabrication ensures your stair system fits — not just physically, but stylistically too.
Your exterior stairs should be as durable as they are attractive. In Thornhill, where homes often feature elegant front porches and walkouts, we install exterior stair and railing systems that withstand Ontario’s weather and elevate curb appeal.
We use materials like pressure-treated lumber, aluminum, composite decking, and galvanized steel — all chosen for their resistance to rot, rust, and UV damage. Our exterior railings come in traditional and modern styles, custom-fit to your home’s architecture.
These systems are built to last — and built to code.
Choosing the right stair contractor is critical to your project’s success. At Modern Stairs Plus, we bring expertise, craftsmanship, and professionalism to every Thornhill staircase we design and install.
Our team manages the entire process — from design consultation and material selection to fabrication and on-site installation. We work directly with homeowners, designers, builders, and architects, ensuring clear communication and consistent quality throughout.
