Most homeowners who reach out to us have a clear picture of what they want at the end — fresh, clean walls, a home that feels renewed, a paint job that holds up. What they often don’t have is a clear picture of what happens between that first phone call and the moment we hand back their space. That gap is where uncertainty lives, and uncertainty is something we’ve worked hard to eliminate from every project we run in Franklin, Brentwood, Spring Hill, Nolensville, and across Williamson County.
What follows is an honest, detailed account of how a Garretson Painting project actually works — not a marketing summary, but a step-by-step picture of what we’re doing at each stage, why we do it that way, and what it means for the quality and longevity of your finished project. If you’re evaluating painting contractors or preparing to schedule your first professional painting project, this is the process you should expect from anyone you hire.
The Estimate Visit: We’re Reading Your Home, Not Just Measuring It
When we come out for a free estimate, we’re doing more than calculating square footage. Before we can give you an accurate scope and a price that reflects what your project actually requires, we need to understand the condition of every surface we’re going to paint.
On interior projects, that means evaluating the existing paint film’s adhesion — whether it’s still bonded firmly to the substrate or beginning to lose its grip at edges and corners. It means looking at drywall repairs from previous projects and assessing whether they were finished to a level that will disappear under new paint or whether they’ll need additional work. It means checking trim and casing for surface profile issues — layers of paint buildup that have obscured profiles, existing brush marks from previous contractors, areas of peeling or adhesion loss that need to be addressed before new paint goes on.
On exterior projects in Franklin, the evaluation is even more consequential. Middle Tennessee’s combination of hot, humid summers, cold enough winters to drive freeze-thaw cycling, and significant rainfall creates conditions that stress exterior paint systems aggressively. We check every caulk joint around windows, doors, trim, and penetrations for cracking, shrinkage, and failure. We evaluate the paint film condition on each elevation — south-facing walls take significantly more UV than north-facing ones and typically show earlier deterioration. We look for any biological growth, wood rot at trim ends and windowsills, and any moisture-related failures that indicate a water intrusion problem that painting over would seal in rather than correct.
All of this informs the scope we bring back to you. Our estimate is a specific plan for your home’s specific conditions, not a generic price per square foot applied universally.
Surface Preparation: The Work That Determines Everything
We tell every client the same thing: the difference between a paint job that looks good for three years and one that looks good for ten is almost entirely in the preparation. Paint is only as good as the surface it’s bonded to, and cutting preparation short to move faster to color is the most common way a paint project fails before it ever gets the chance to succeed.
On interior projects, our preparation phase includes scraping any areas of loose or failing paint back to a stable edge, sanding those transitions to a feathered profile that won’t read as a ridge under the new film, filling nail holes and hairline cracks with appropriate filler, skim-patching any drywall damage or previous repair work that needs additional attention, and washing surfaces where grease, chalk, or contamination would compromise adhesion.
Caulking is a preparation step that homeowners often don’t realize is part of the painting process, but it’s one of the most important things we do. Every gap at the junction between trim and wall, every window and door casing where the casing meets the adjacent drywall, every baseboard where it meets the wall above it — these are places where air infiltration, movement, and moisture all create the conditions for early paint failure if the joint isn’t properly sealed before painting. We recaulk every joint that shows cracking, shrinkage, or separation with a paintable acrylic latex caulk that has the elongation to tolerate the seasonal movement Middle Tennessee homes experience through a full year of temperature and humidity cycling.
On exterior projects, preparation is even more extensive. Power washing to remove chalking, biological growth, and surface contamination is followed by scraping and sanding failing areas, replacing any caulk that has failed at joints and penetrations, and addressing any wood rot at trim, fascia, or sill areas that needs repair before paint goes on. Painting over deteriorated wood or failed caulk doesn’t fix those problems — it covers them temporarily and accelerates the failures that follow. We don’t do that.
Primer: Specified to the Surface, Not Applied Universally
Every surface we paint gets evaluated for its primer requirement, and that requirement varies depending on what the surface is, what’s on it, and what topcoat is going over it. We don’t use one primer on everything, because the right primer for new drywall joint compound is not the right primer for a previously painted exterior surface with adhesion concerns, and neither of those is the right primer for a stain-prone substrate or a slick trim surface that needs enhanced bonding.
On areas of bare or repaired drywall, we use a high-quality drywall primer that seals the porosity differential between joint compound and drywall face paper so the topcoat develops uniform sheen across the entire surface. On slick or glossy existing coatings, we use an adhesion-promoting primer that gives the new coat mechanical grip on a surface that standard products wouldn’t bond to reliably. On any areas where stain bleed is a risk — knots in wood trim, smoke or water-stained drywall, tannin-producing wood species — we specify an oil-based or shellac-based stain-blocking primer, because water-based products cannot seal those materials effectively regardless of how many coats are applied over them.
When we specify primer at your estimate, we’ll tell you what we’re using and why. If you ever hire a painting contractor who uses the same primer everywhere without discussion, ask them why — and listen carefully to the answer.
Application: Sequence, Technique, and Wet-Edge Management
Once surfaces are prepared and primed, topcoat application follows a deliberate sequence: ceilings before walls, walls before trim. This order ensures that the most detail-intensive, precise work happens on fresh surfaces, and that any overspray or drips from the broad work above are captured by the work that follows rather than falling on finished surfaces below.
Our interior application combines cutting in along edges, corners, and trim lines with brush work and rolling the open field areas with the appropriate nap roller for that surface texture. The quality of the cut-in work — the straightness and consistency of the line at every ceiling-wall junction, the clean termination of wall color at trim without ragged edges or paint loading — is where the most visible quality difference between professional and amateur work concentrates. We take that work seriously, because it’s what you see every time you look at a room in the right light.
On exterior projects, we spray large field areas and back-roll immediately — working the sprayed paint into the surface texture while it’s still wet to ensure proper penetration and film build rather than bridging over surface irregularities. Trim, windows, and doors receive brush application regardless of the field technique, because brush work builds the film thickness and penetration that these high-contact, moisture-exposed surfaces require for durability.
Between coats, we respect the re-coat windows that the products require. Applying a second coat before the first has reached adequate hardness creates a soft, poorly bonded film that fails earlier than properly cured paint would. In Franklin homes during the heating season, when forced-air systems drop indoor humidity and accelerate drying, we monitor conditions and adjust timing accordingly. On trim products — the waterborne alkyds we use on doors, casing, and baseboards throughout Williamson County homes — we explain to every client that full hardness develops over fourteen to thirty days after application, and we recommend treating trim gently during that cure window to protect the finish we’ve just put on.
Cleanup and Protection Throughout the Project
We protect what we’re not painting as carefully as we prepare what we are. Drop cloths on floors and furniture, careful masking of hardware, fixtures, and glass, and daily cleanup of the work area at the end of each day are non-negotiable parts of how we work. A professional painting project should not leave a home in a state of prolonged disruption — your spaces should be accessible and functional throughout the project, with the work area cleaned and organized at the close of each working day.
At the end of the project, we remove all masking, drop cloths, and equipment, clean up any paint that has gotten onto surfaces it shouldn’t have, reinstall hardware we removed for painting, and return the space to the condition it was in before we arrived — except for the surfaces we painted, which should look significantly better.
The Final Walkthrough: We Don’t Consider the Project Done Until You Do
Every Garretson Painting project concludes with a formal walkthrough between us and the homeowner. We walk every painted surface together and evaluate it — cut lines, trim work, field coverage, caulking, any areas of concern — under the actual lighting conditions of the space, including raking light from a portable work lamp that reveals sheen inconsistencies and missed sections that overhead lighting obscures.
This walkthrough is not a formality we rush through. It is the moment where we confirm together that the project was completed to the standard we agreed on. If anything doesn’t meet that standard, we address it before we consider the project finished. Our warranty covers the work we deliver, and the walkthrough is where we verify that delivery.
