What Happens If Rotten or Damaged Wood Is Uncovered?
Exterior painting occasionally turns into detective work. From the ground, a piece of trim might look like it just needs scraping and paint. Once the loose material is removed, however, it can become clear that the wood itself has deteriorated. Let's be clear. Paint isn't going to fix rotten wood. Depending on the extent of the damage, deteriorated areas may need to be repaired or replaced before painting continues. The painter should communicate what was discovered, explain the recommended repair, and clarify whether that work is included in the original estimate or requires an additional cost.
This is especially worth discussing when you own an older Chicagoland home with wood siding, fascia, soffits, window trim, or other exposed wood components. Years of moisture and freeze-thaw cycles can take their toll, even when everything looks relatively fine from the driveway.
How Long Should Exterior Paint Prep Take?
There's no magic number. A newer home with a relatively sound existing coating might require significantly less preparation than a 70-year-old house with peeling wood siding and layers of previous paint. Prep time can depend on the home's size, surface material, coating condition, accessibility, amount of peeling paint, necessary repairs, and even the weather. In some cases, prep can represent a significant portion of the overall project. And that's not wasted time. The finish coat gets all the glory because that's the part you actually see. But the work underneath it plays a major role in how the finished project looks and how well the coating performs.
Why Do Two Painting Estimates Have Such Different Prep?
Here’s an example of what two different estimates could look like:
Painter A: Wash, scrape loose paint, sand appropriate areas, caulk gaps, spot-prime bare wood, and apply two finish coats.
Painter B: Prep and paint exterior.
"Prep" can mean different things from one painting company to another, which is why comparing estimates based only on the bottom-line price can be misleading. One contractor may have included substantial scraping, sanding, caulking, and priming. Another may be planning a much lighter prep process. A few hundred or even a few thousand dollars between estimates suddenly looks different when you realize the scopes aren't actually the same.
How Should You Compare Prep Between Two Painting Estimates?
Don't be afraid to ask painters to get specific. When comparing estimates, find out exactly what each contractor plans to do before the first finish coat is applied. Ask what gets washed, how peeling paint is handled, where sanding is performed, what gets caulked, when primer is used, and how unexpected wood repairs are handled. You should also ask whether those steps are specifically included in the written scope.
You want the right prep for the condition of your particular home. That's also why an in-person evaluation matters. Your home's age, materials, previous coatings, sun exposure, moisture issues, and current condition all influence what preparation makes sense.
Why Exterior Prep Matters So Much in Chicagoland
Chicago-area homes ask a lot from exterior paint. Hot, humid summers are followed by cold winters, snow, ice, moisture, and repeated freeze-thaw cycles that can cause wood siding and trim to expand and contract. Older housing stock adds another wrinkle, with many homes having wood components that have already lived through decades of weather and multiple generations of paint. Proper preparation gives new paint the best possible surface to bond to while also helping your painter identify peeling paint, cracks, exposed wood, or other problems before they're covered up. And once the prep is complete, choosing the
best temperatures for exterior painting in Chicagoland can play an important role in how well that new coating performs.
So, How Much Prep Should Your Painter Actually Do?
Here’s the takeaway: Enough to address the condition of your house properly. No more, no less. That might mean relatively straightforward washing, light scraping, caulking, and spot priming on one home. On another, it could involve extensive scraping, sanding, priming, and wood repairs before a gallon of finish paint ever gets opened. The important thing is knowing what you're paying for.
When you're comparing
exterior painting estimates, don't just skip to the price at the bottom. Spend a few minutes looking at the prep scope. Because when the painting is finished, you'll see the color. A few years later, you may find out how good the prep was.
Frequently Asked Questions
Do painters remove all old exterior paint? Usually not. Painters typically remove loose, peeling, or failing paint. Well-adhered existing paint can often remain and be properly prepared for recoating.
Do you have to prime before exterior painting? Not always. Bare wood, repairs, stains, and problem areas often need primer, while an exterior in good condition may only require spot priming.
How long does exterior paint prep take? It depends on the home's size, age, condition, and necessary repairs. A well-maintained exterior may need minimal prep, while an older home can require considerably more.
Should painters power wash before painting? Exterior surfaces should generally be cleaned before painting, and power washing is one common method. The surface should be cleaned without damage and allowed to dry before painting.
Can you paint over peeling paint? No. Loose or peeling paint should be removed to a sound edge, with sanding and priming performed where needed before repainting.
Is wood repair normally included in exterior painting? It depends on the estimate. Minor repairs may be included, while larger carpentry work is often priced separately and should be discussed before work continues.
