You've narrowed your list of potential contractors to a handful of candidates. Each one claims quality workmanship and satisfied customers. How do you separate genuine craftsmanship from marketing talk?
A contractor's portfolio tells stories that sales pitches cannot. Completed projects reveal technical skill, attention to detail, and consistency across different home styles. Knowing what to examine helps you spot the difference between professionals who take pride in their work and those who simply get jobs done.
Here's how to read a siding portfolio like someone who understands what quality actually looks like.
Start with Volume and Variety
How many completed projects can the contractor show you? A handful of photos suggests limited experience or selective presentation. Established companies accumulate extensive portfolios over years of continuous work.
Look for variety within that volume. Different home styles present distinct challenges. Ranch houses require different techniques than two-story colonials. Victorian-era homes with ornate trim demand skills that simple rectangular structures never test. A contractor who has handled diverse architectural styles demonstrates adaptability and broader expertise.
Geographic variety matters in Colorado specifically. Homes in Boulder's foothills face different weather exposure than properties in Westminster or Thornton. Mountain-adjacent installations deal with heavier snow loads and more extreme temperature swings. Seeing work across various Denver-area neighborhoods suggests familiarity with regional conditions.
Examine Before and After Comparisons
Quality portfolios include before and after images of the same properties. These comparisons reveal transformation scope and help you assess improvement quality.
Study the before photos carefully. What condition was the existing siding in? Severely deteriorated exteriors often hide structural problems beneath. A contractor willing to show challenging starting points demonstrates confidence in handling complex situations.
After photos should depict clean, finished results with consistent lines and proper detailing. Zoom in mentally on corners, window frames, and transition points. These areas expose craftsmanship differences most clearly.
Be wary of portfolios showing only after shots. Without context, impressive-looking results might represent straightforward installations on newer homes rather than skilled transformations of problematic properties.
Pay Attention to Detail Shots
Wide-angle photos of finished homes look attractive but hide technical quality. Request close-up images of specific elements where skill differences become visible.
Corner treatments deserve particular attention. Outside corners should show perfectly vertical lines without gaps between posts and adjacent panels. Inside corners require different approaches and similar precision. Sloppy corner work creates both aesthetic problems and potential water entry points.
Window and door surrounds reveal installer competence clearly. J-channels should fit tightly against frames with uniform reveals. Caulking lines need to appear clean and consistent rather than globbed or uneven. Flashing, though often hidden, sometimes appears in detail shots and indicates proper weatherproofing technique.
Soffits and fascia complete the picture along rooflines. These elements require careful fitting around gutters, vents, and architectural features. Rushed installations show gaps, misalignments, or visible fasteners that quality work conceals.
Look for Challenging Installations
Any crew can handle straightforward rectangular walls. Complex architectural features separate skilled contractors from average ones.
Dormers present particular challenges. Multiple angled surfaces meet at peaks requiring precise cutting and fitting. Water management around dormer walls demands proper flashing technique. Portfolios showing clean dormer work indicate crews comfortable with complexity.
Bay windows and bump-outs create similar tests. These projections interrupt flat wall planes with multiple corners and transitions. Poorly executed bay window surrounds look obviously amateur from street level.
Mixed material applications demonstrate advanced capability. Some homes feature fiber cement on main walls with board-and-batten accents or stone veneer sections. Coordinating different materials while maintaining weather protection requires experience beyond basic panel installation.
Assess Consistency Across Projects
Quality contractors maintain standards regardless of project scale or client budget. Compare results across different homes in the portfolio.
Do modest ranch houses receive the same attention to detail as larger custom properties? Corners on a $15,000 project should look as clean as those on a $40,000 installation. Contractors who deliver inconsistent quality based on job size will likely classify your project somewhere on that spectrum.
Timeline matters too. Ask when various portfolio projects were completed. A contractor showing only recent work might lack long-term track record. Seeing quality installations from five or ten years ago suggests sustained commitment to standards.
Request Project-Specific Information
Photos tell part of the story. Additional context fills important gaps.
Ask about materials used on projects you find impressive. Knowing whether striking results came from premium James Hardie fiber cement, quality vinyl like ASCEND by Alside, or budget materials helps you understand what to expect at various price points.
Project duration information reveals efficiency. How long did that two-story colonial take from start to completion? Excessively long timelines suggest disorganized crews or complications from poor planning.
Challenge history provides valuable insight too. Ask what problems arose during specific projects and how the contractor resolved them. Every exterior renovation encounters surprises. How companies handle unexpected issues matters as much as performance under ideal conditions.
Verify Portfolio Authenticity
Unfortunately, some contractors display work they didn't actually perform. Stock photos from manufacturers, images borrowed from other companies, or pictures from subcontracted jobs sometimes appear in misleading portfolios.
Several verification approaches help confirm authenticity. Ask for addresses of completed projects you could drive by to see in person. Legitimate contractors with satisfied customers welcome this request. Those with fabricated portfolios deflect or make excuses.
Cross-reference with online reviews. Customers who post detailed testimonials sometimes include photos matching portfolio images. Consistency between independent reviews and company-presented work builds confidence.
Request references from specific portfolio projects. Speaking with homeowners whose installations appear in marketing materials provides direct verification while offering candid feedback about the actual experience.
Watch for Red Flags
Certain portfolio characteristics suggest potential problems worth noting.
Extremely small portfolios from contractors claiming years of experience raise questions. Where did all those previous projects go? Companies proud of their work accumulate documentation over time.
Portfolios featuring only one material type might indicate limited capability. A contractor showing exclusively vinyl installations may lack experience with fiber cement or other options you're considering.
Absence of detail shots often means those details don't hold up to examination. Contractors confident in their craftsmanship happily show close-ups. Those hiding technique deficiencies keep cameras at a distance.
Heavily filtered or edited photos warrant skepticism. Some post-processing improves image quality legitimately. Excessive manipulation might disguise flaws that appeared in original documentation.
What Quality Craftsmanship Looks Like
Knowing specific markers of excellent work helps you assess portfolios more effectively.
Straight horizontal lines indicate proper installation technique. Siding courses should run parallel across entire wall sections without visible waviness or deviation. Achieving this consistency requires attention to starter strips, level checking throughout installation, and adjustment for imperfect underlying surfaces.
Uniform panel spacing shows manufacturer guidelines were followed. Most siding products require specific gaps between panels to accommodate thermal expansion. Panels butted too tightly buckle in summer heat. Excessive spacing looks sloppy and allows moisture penetration.
Clean cuts around obstacles demonstrate precision. Electrical meters, hose bibs, vents, and other penetrations require careful fitting. Rough cuts or visible gaps around these elements indicate rushed work.
Invisible fasteners reflect proper technique. Face-nailed panels should show fasteners only where unavoidable and necessary. Excessive visible nailing suggests inexperience or carelessness.
