Repairs Worth Doing Before Exterior Painting

When embarking on an exterior house painting project, it's easy to get caught up in the excitement of selecting colors and finishes. But painting is just the final step. Preparatory work is essential to ensure that the new paint adheres well, lasts longer, and looks impeccable. In Fort Collins, where elements can be particularly harsh, homeowners should be especially diligent in their pre-painting preparations.


Siding is a Repair Worth Doing Before Exterior Painting

Survey Your Siding

Before you dive into the painting process, it's essential to inspect your home's exterior. Check for water damage, signs of mold or mildew, cracks, rot, or any other damage to the siding. Addressing these issues before painting can significantly improve the lifespan and appearance of your new paint job.


Some things to look for when surveying your siding:

  • Water Damage: Over time, the exterior of homes can experience water damage due to rain, snow, or even sprinkler systems. Look for signs such as peeling paint, discolored patches, or swollen wood.

  • Mold and Mildew Signs: Dark or green patches, especially in shaded areas, can be a sign of mold or mildew growth. These not only damage the paint but can also affect the underlying wood.

  • Check for Cracks: Cracks can allow moisture to penetrate beneath the paint, causing it to bubble or peel. They can also be entry points for pests.

  • Inspect for Rot: Soft or crumbly spots, especially at the base of wooden siding or near the ground, might indicate wood rot.

  • Other Damage Types: Look out for warping, chipping, or any other forms of deterioration that may affect the siding's integrity.


Frame Repair is Worth Doing Before Exterior Painting

Secure Window and Door Frames

Loose window or door frames can spell trouble for your painting project. Not only can they get damaged during painting, but they can also result in an uneven finish. Ensure they're secure before you start.


Risks of Loose Frames

  • Potential Damage: Painting around a loose frame might cause it to shift, leading to damage or breaking.

  • Uneven Finish: As the frame moves, it might cause the fresh paint to smudge, leading to an unsightly finish.

  • Increased Maintenance: Loose frames can lead to gaps that might allow water or pests to infiltrate, causing potential damage and adding to future maintenance needs.

How to Secure Frames

  • Tighten Screws: Over time, screws can become loose. Tightening them can often fix minor stability issues.

  • Sealant and Caulk: Apply sealants or caulk to fill gaps and add an extra layer of protection.

  • Bracket Reinforcement: For frames that have significant wobbling issues, consider adding or replacing brackets for added stability.


Trim is worth repairing before exterior painting begins

Attend to the Trim

The trim around windows and doors can significantly impact the overall appearance. If it's cracked or worn out, it can detract from even the most impeccable paint job. Check and repair or replace any damaged trim for the best results.


Importance of Trim

  • Visual Impact: The trim serves as a frame for windows and doors, accentuating their structure and providing a polished look to a building's exterior or interior.

  • Contrast and Complement: Often painted in a color contrasting the main body of the house, the trim can make architectural details pop, giving character to the entire property.

  • Unified Appearance: Properly maintained trim creates a cohesive look, signaling attention to detail and care in home upkeep.

Inspecting the Trim

  • Physical Examination: Feel for rough edges, splinters, or any uneven surfaces that might indicate wear.

  • Visual Scan: Look for visible cracks, chips in the paint, rot, or any signs of mildew or mold.

  • Functional Check: Windows and doors should open and close smoothly without catching on the trim.

Repairing and Replacing Trim

  • Clean and Sand: Before any repair, clean the trim of dirt or old paint and sand it down for a smooth surface.

  • Fill and Seal: Use wood filler to address minor cracks or holes, and always seal them properly to prevent moisture ingress.

  • Replacement: If the trim is extensively damaged or rotted, it's often best to replace it entirely. This ensures longevity and reduces future maintenance needs.


Properly caulking seams and gaps is important before starting an exterior painting project.

Caulk the Seams

Use a high-quality caulking compound to seal any gaps where walls meet trim. This prevents water infiltration and gives a smoother, more professional finish.


Purpose of Caulking

  • Barrier Creation: Caulking acts as a barrier, preventing external elements like rain, snow, and pests from entering the home.

  • Energy Efficiency: Proper sealing of gaps can prevent drafts, potentially reducing energy costs by maintaining interior temperatures.

  • Aesthetic Enhancement: It ensures a seamless appearance between walls and trim, elevating the overall look of a painted surface.

Choosing the Right Caulk

  • Material Compatibility: Ensure the caulk you choose is suitable for the materials you're working with, whether it's wood, brick, or vinyl.

  • Durability: Opt for a caulking compound known for its longevity, especially for exteriors exposed to varying weather conditions.

  • Flexibility: Caulks that remain slightly flexible after drying can better accommodate the natural expansion and contraction of building materials.

  • Paintability: Ensure your chosen caulk can be painted over if you're planning to paint the area after caulking.

Caulk Application Tips:

  • Surface Preparation: Before applying, clean the area of any dirt, old paint, or debris to ensure the caulk adheres well.

  • Tool Choice: Utilize a high-quality caulking gun for precise application.

  • Smooth Finish: After applying, use a caulk-smoothing tool or your fingertip to press the caulk into the seam and create a smooth line.

  • Clean Up: Quickly clean any mistakes or excess with a damp cloth before the caulk dries.

  • Drying Time: Allow the caulk to dry thoroughly before painting over it. Refer to the manufacturer's instructions for specific drying times.


Powerwashing is a good way to prep your homes exterior for painting.

Prep Previously Painted Surfaces

If your home's exterior has been painted before, take time to clean and sand the surfaces. This ensures the new paint adheres well and looks smooth. A combination of pressure washing and sanding is often the best approach.


Importance of Prepping

  • Adhesion: Properly prepped surfaces ensure the new paint adheres effectively, reducing the chances of peeling or chipping.

  • Smoothness: Cleaning and sanding eliminate imperfections, leading to a smoother finish.

  • Durability: A well-prepared surface can enhance the lifespan of the paint job, protecting your investment for longer.

Cleaning Techniques

  • Pressure Washing: Covers large areas quickly, making it ideal for exterior walls. Use appropriate pressure settings to avoid damage, especially on older homes or delicate materials.

  • Hand Scrubbing: Ideal for areas needing more attention or where a pressure washer might be too aggressive. Mild detergent or specially formulated cleaning solutions can be used.

Sanding Procedures

  • Protective Gear: Wear goggles, gloves, and a dust mask, especially during sanding, to protect against dust and debris.

  • Choosing Grit: 80-100 grit sandpaper is commonly used for exterior pre-paint sanding, but always consider the condition and material of the surface.

  • Electric Sanders: Tools like orbital or palm sanders can expedite the process, especially on large surfaces.

  • Hand Sanding: Essential for nooks, crannies, and delicate areas where precision is crucial.

  • Dust Removal: After sanding, use a tack cloth or lightly dampened rag to remove residual dust.

  • Eco-Friendly Disposal: Dispose of paint chips and dust in an environmentally responsible manner.


Gutters are an often overlooked repair before starting an exterior painting project.

Inspect Your Gutters

Damaged or old gutters can impact the overall aesthetic. Repair or replace them as necessary before painting to ensure consistency in your home's appearance.


Signs of Damage

  • Visible Holes or Cracks: Over time, gutters may develop breaches that impede their function.

  • Sagging Sections: Gutters that sag or pull away from the home need attention.

  • Rust Spots: Especially prevalent in older metal gutters.

  • Pooling Water: Indicates a potential blockage or improper slope.

  • Peeling Paint or Mold Growth: Mold growth on the house near the gutters can signal overflow issues.

Repair vs. Replace

  • Minor Damages: Small holes, loose brackets, or minor rust can often be repaired.

  • Extensive Damages: If damages are widespread or the gutters are old, consider a complete replacement.

  • Material Consideration: Modern gutters come in various materials, such as aluminum, copper, steel, and vinyl. Each has its own lifespan and maintenance needs.
