Markham Siding

Exterior Siding Solutions for Markham Homes

Markham is home to a broad range of residential construction, from established neighborhoods with aging exteriors to newer subdivisions and custom-built homes. As a result, siding projects in Markham often focus on updating older materials, improving wall performance, and integrating new finishes with existing structures.


Century Aluminum completes residential siding projects throughout Markham on low- to mid-rise homes where proper access, wall layout, and detailing allow for system-based installation. Every project is approached with a focus on long-term durability, clean finishes, and compatibility with the home’s structure.


All projects referenced on this site are completed by Century Aluminum using in-house crews and consistent installation standards.

Why Markham Siding Projects Require Planning

Many homes in Markham have undergone multiple renovation phases over time. It’s common to encounter additions, garage conversions, or partial exterior upgrades completed years apart using different materials or methods.


These conditions can introduce challenges such as:


  • Mixed wall assemblies across elevations
     
  • Changes in wall depth and insulation
     
  • Uneven substrates behind existing siding
     
  • Transitions between old and new construction
     

Addressing these issues early allows siding systems to be designed properly rather than forced to fit existing inconsistencies.

Project Scope

From Full Replacements to Renovation Tie-Ins

Siding projects in Markham typically fall into several categories:


  • Full exterior siding replacements on older homes
     
  • Partial siding upgrades tied to renovations
     
  • Additions requiring new siding to blend with existing finishes
     
  • Dormers and bay build-outs
     
  • Exterior modernization projects
     

Because many projects involve tying new siding into existing structures, attention to wall preparation and system sequencing is critical.

Material Selection

Choosing Materials That Match Design and Exposure

Material selection in Markham is influenced by architectural style, renovation goals, and exposure conditions. Homeowners often look for materials that improve curb appeal while reducing long-term maintenance.


Common siding materials include:


  • Vinyl siding for profile variety and efficiency
     
  • Aluminum siding for clean lines and moisture resistance
     
  • Steel siding for rigidity and impact resistance
     
  • Architectural accent materials for contrast and depth
     

Century Aluminum works with all major suppliers to source compatible profiles and colors, helping ensure new siding integrates cleanly with existing exteriors or renovation designs.

Wall Preparation

What’s Behind the Siding Matters

Proper wall preparation is a key factor in the performance and appearance of siding systems. In Markham, this is especially important on homes with renovation history or older construction.


Preparation may include:


  • Repairing damaged or uneven substrates
     
  • Installing continuous housewrap when insulation is not added
     
  • Integrating rigid insulation to improve wall performance
     
  • Detailing transitions between original and added structures
     

This system-based approach supports straight wall lines and long-term durability.

INSTALLATION STANDARDS

System-Based Installation for Consistent Results

All Markham siding projects are installed following system-based practices that account for movement, moisture management, and long-term performance. Proper fastening, flashing, and sequencing are maintained across all elevations.


Installation guidelines and best practices are outlined on the Siding Installation page.

Planning

Evaluate the Home Before Selecting Materials

Successful siding projects in Markham start with understanding the home’s structure, renovation history, and wall condition. Reviewing these factors early helps prevent mismatched materials, uneven finishes, and unnecessary adjustments during installation.


Planning resources include material comparisons, system design details, and cost considerations.
