Exterior House Painting in Thornton: What to Expect From Start to Finish

Painting your home's exterior is one of the most impactful improvements you can make. A fresh coat of paint transforms curb appeal, protects your siding from Colorado's demanding climate, and can add thousands of dollars to your property value. But if you've never been through the process before, you might wonder what's actually involved.

At AXXESS Painting & Remodeling, we've painted hundreds of homes throughout Thornton, Westminster, Denver, and the surrounding Front Range communities. Here's a complete guide to what you can expect when you hire professionals to paint your home's exterior, from that first phone call to the final walkthrough.

Phase 1: The Initial Consultation and Estimate

Scheduling Your Free Estimate

The process begins when you contact a painting contractor to schedule an estimate.

At AXXESS Painting & Remodeling, we offer free consultations where our team assesses your home and discusses your vision for the project. This initial meeting typically takes 30-60 minutes depending on your home's size and complexity.

What Happens During the Assessment

During the consultation, your painting contractor will:

Inspect the exterior surfaces. We look for peeling paint, cracking, wood rot, damaged siding, mildew, and other issues that need addressing before painting can begin. The current condition of your exterior significantly affects both preparation time and final cost.

Measure the paintable surface area. Square footage is the primary factor in determining project cost. We measure all walls, trim, soffits, fascia, and any other surfaces you want painted. A typical home has between 1,500 and 4,000 square feet of paintable exterior surface.

Discuss your goals and preferences. Are you keeping the same colors or making a change? Do you want the trim and doors painted different colors? Are there specific problem areas you're concerned about? This conversation helps us understand exactly what you're looking for.

Assess accessibility challenges. Homes with multiple stories, steep rooflines, dormers, or difficult-to-reach areas require additional equipment like scaffolding or lifts. These factors affect both timeline and cost.

Review your home's siding material. Different materials require different preparation, primers, and paint types. Wood, stucco, brick, vinyl, and aluminum each have specific requirements for optimal results.

Understanding Your Estimate

A thorough estimate should clearly outline:

The total project cost broken down by labor and materials. Most Thornton exterior painting projects cost between $1.50 and $4 per square foot, meaning a typical home runs $4,000 to $12,000 depending on size and complexity.

The scope of work including which surfaces will be painted, the number of coats, and the type of paint being used.

Any necessary repairs such as wood replacement, caulking, or surface preparation beyond standard cleaning and scraping.

Payment terms and any warranty information.

Phase 2: Color Selection and Planning

Choosing Your Colors

If you're changing colors, this is your chance to reimagine your home's appearance. Your painting contractor can offer guidance on color selection, but here are key considerations for Thornton homes:

Consider Colorado's intense UV exposure. At our elevation, UV radiation is about 25% stronger than at sea level. Darker colors fade faster in our climate. If you choose bold or dark shades, invest in premium paint with UV inhibitors and fade-resistant pigments.

Think about your home's fixed elements. Your roof color, stone or brick accents, landscaping, and neighboring homes all influence which paint colors will look best. The goal is creating harmony, not clashing.

Check HOA requirements. Many Thornton neighborhoods have approved color palettes. Review these restrictions before falling in love with an unusual shade. Your contractor can help you find options that express your style while meeting community guidelines.

Test before committing. Paint large sample patches on multiple sides of your home and observe them at different times of day. Colorado's bright sunlight can dramatically change how a color appears compared to what you see on a paint chip.

Scheduling the Project

Once you've approved the estimate and selected colors, your contractor will schedule the project. The best exterior painting season in Colorado runs from late spring through early fall when temperatures are mild and weather is relatively stable.

Professional painters check long-range weather forecasts and avoid scheduling work before predicted rain, snow, or extreme temperature changes. Most exterior paints require temperatures between 50°F and 85°F for proper application and curing.

Phase 3: Preparation Work

This phase is where professional painters earn their reputation. Proper preparation is the foundation of a paint job that looks beautiful and lasts for years. Rushing or skipping prep work leads to premature peeling, cracking, and paint failure.

Protecting Your Property

Before any cleaning or painting begins, your painter will protect elements that shouldn't be painted:

Landscaping protection. Drop cloths and plastic sheeting cover plants, shrubs, and flower beds near the house. Outdoor furniture is moved away from work areas.

Window and door masking. Painter's tape and plastic protect glass, hardware, and fixtures from overspray and drips.

Light fixtures and address numbers. These are either masked in place or temporarily removed.

Walkways and driveways. Drop cloths prevent paint splatters on concrete and pavement.

Cleaning the Exterior

All that dirt, debris, cobwebs, and mildew on your siding will prevent new paint from properly adhering to the surface. Professional painters typically use pressure washing to clean exterior surfaces.

Pressure washing removes: Dirt and dust accumulation from years of exposure Mildew and mold growth Loose, flaking paint Cobwebs and insect debris Pollen and environmental buildup

The pressure level matters. Too much pressure can damage siding, especially softer woods like cedar. Professional painters know how to adjust pressure appropriately for different materials. After washing, your home needs 24-48 hours to dry completely before painting can begin.

Scraping and Sanding

Any loose or peeling paint must be removed before new paint is applied. Painting over flaking paint creates an uneven surface and the new paint will eventually fail in those areas.

Scraping removes paint that's actively lifting or bubbling. Professional painters work systematically around the house, paying extra attention to areas where previous paint is failing.

Sanding smooths rough edges where paint was scraped and removes the glossy finish on previously painted surfaces. This "scuffing" helps new paint adhere better. For areas with glossy or semi-gloss finishes, sanding is essential for proper adhesion.

Repairs and Caulking

This is the time to address any damage discovered during the initial assessment:

Wood replacement. Rotted trim, damaged siding, or deteriorated fascia boards should be replaced before painting. Painting over compromised wood wastes money since the paint will fail as the wood continues to deteriorate.

Filling holes and cracks. Exterior-grade filler smooths nail holes, minor cracks, and surface imperfections. These repairs create an even surface for paint application.

Caulking. Fresh caulk seals gaps around windows, doors, trim boards, and anywhere different materials meet. Proper caulking protects against water intrusion and insect damage while creating clean, finished lines. This step is particularly important in Colorado where our dramatic temperature swings cause materials to expand and contract significantly.

Priming

Primer serves several critical functions:

It helps paint adhere properly to the surface, especially over bare wood, patched areas, or when changing colors dramatically.

It blocks stains from bleeding through the topcoat. Wood knots, water stains, and rust all require primer to prevent them from showing through your new paint.

It provides a consistent base that helps the topcoat apply evenly and achieve true color.

Areas with bare wood, rust spots, heavy staining, or significant color changes require primer. Some modern paints are "self-priming," but professional painters still recommend separate primer for problem areas.

Phase 4: Painting

With preparation complete, the actual painting begins. This is the phase most homeowners envision when they think about an exterior painting project.

Painting Order and Technique

Professional painters work systematically, typically following this order:

• Start at the top. Painters work from the highest points downward, catching any drips as they go. This usually means starting with soffits and fascia, then moving to upper walls before lower walls.
• Trim and detail work. Painters use brushes for precise work around windows, doors, corners, and architectural details. This "cutting in" creates clean edges where different colors meet.
• Large wall sections. Rollers cover broad, flat surfaces efficiently. Professional painters may also use sprayers for certain applications, though spraying requires extensive masking and works best in specific conditions.
• Doors and shutters. These accent pieces are typically painted last after the main body of the house is complete.

Number of Coats

Most exterior paint jobs require two coats for best results. The first coat seals and protects the surface while the second coat provides full coverage, true color, and maximum durability.

Between coats, paint needs time to dry. Most exterior paints require 4-6 hours of drying time between coats, though this varies based on temperature, humidity, and the specific product. Your painter will follow manufacturer guidelines for proper recoating times.

If you're making a dramatic color change, especially from dark to light, you may need additional coats to achieve full coverage.

Weather Considerations

Colorado weather can be unpredictable, and professional painters monitor conditions carefully:

• Temperature range. Most paints apply best between 50°F and 85°F. Too cold, and paint won't cure properly. Too hot, and it dries too fast, causing brush marks and adhesion problems.
• Humidity and moisture. Paint shouldn't be applied if rain is expected within 24 hours. Moisture interferes with proper drying and can cause immediate paint failure.
• Direct sunlight. Working in shade helps avoid problems from paint drying too quickly. Painters often follow the sun around the house, working on shaded sides while other areas bake in direct sunlight.
• Wind. High winds carry dust and debris that can stick to wet paint and make spray application impossible.

Phase 5: Completion and Cleanup

Final Inspection and Touch-Ups

Once painting is complete, a quality contractor conducts a thorough walkthrough:

• Checking for missed spots and ensuring complete coverage on all surfaces
• Verifying clean, straight lines where different colors meet
• Inspecting high-detail areas around windows, doors, and trim
• Addressing any drips, runs, or imperfections

Touch-up work corrects any minor issues discovered during inspection. This attention to detail separates professional results from amateur work.

Cleanup

Professional painters leave your property as clean as they found it:

Removing all masking materials from windows, doors, and fixtures Collecting drop cloths and disposing of waste materials properly Cleaning up any paint drips from walkways or hardscape Returning outdoor furniture to its original positions Properly disposing of paint and materials according to local regulations

Final Walkthrough With You

Before the project is officially complete, your painter should walk through the finished work with you. This is your opportunity to:

Review all painted surfaces and ensure you're satisfied with the results Ask questions about paint care and maintenance Discuss warranty coverage and what it includes Receive any leftover paint for future touch-ups

How Long Does Exterior Painting Take?

The timeline varies based on home size, surface condition, and weather, but here are general expectations for Thornton homes:

Small single-story home (under 1,500 sq ft): 2-4 days Average two-story home (1,500-2,500 sq ft): 4-7 days Large or complex home (2,500+ sq ft): 1-2 weeks or more

These timelines include preparation, painting, and cleanup. Homes requiring extensive repairs, multiple stories, or complex architectural details take longer. Weather delays can also extend the timeline.

Maintaining Your New Paint Job

Once your exterior painting project is complete, proper maintenance extends its lifespan:

• Annual inspections. Walk around your home once a year looking for signs of wear, peeling, or damage. Catching problems early makes repairs simple and prevents larger issues.
• Gentle cleaning. Rinse off dirt and debris periodically with a garden hose. Avoid pressure washing freshly painted surfaces for at least a year.
• Prompt touch-ups. Address chips, scratches, or peeling immediately before moisture can penetrate and cause larger problems. Keep leftover paint for exactly this purpose.
• Trim vegetation. Keep plants, shrubs, and trees trimmed away from painted surfaces. Constant contact with foliage traps moisture and causes premature paint failure.

With proper maintenance and quality paint, your exterior paint job should last 7-10 years in Colorado's climate before needing a full repaint.
