On a House This Old, You Test the Paint Before You Sand It

Exterior painting quotes are unusually hard for a homeowner to compare, because the thing being priced is mostly invisible. Two contractors look at the same house and one comes back with a number that is twice the other. Neither is necessarily dishonest. They are quoting two different scopes of work, and the difference between them is almost entirely in preparation, which is the part of the job that will be buried under paint by the time anyone can inspect it.

Understanding what drives the number lets you read a quote properly, ask three or four questions that reveal what is actually included, and tell the difference between a bid that is cheap and a bid that is incomplete. Anyone who has searched for house painting cost near me and found figures ranging across a factor of three has run into exactly this: the published ranges are averaging jobs that are not the same job.

Surface area, and why it is not square footage of the house

Painters do not price from the floor area of a home. They price from the surface area to be coated, which is a different and larger number. A single story house with tall walls, deep eaves, a lot of trim and several dormers can have more paintable surface than a two story house of greater floor area.

The elements that add surface without adding much floor area are eaves and soffits, fascia boards, exposed rafter tails, window and door casings, porch ceilings, columns, railings, garage doors and shutters. Anyone comparing quotes should first establish that both bids cover the same list of these, because the most common source of a difference is that one bid included the eaves and the other did not.

Substrate is the second largest variable

What the house is made of changes the labour substantially.

Stucco is very common in this region and it behaves in its own way. It is porous, it soaks up paint, and coverage rates are much lower than on a smooth surface, meaning more material for the same area. Textured stucco has to be worked into rather than rolled across. And stucco cracks, so crack repair is a real line item.

Wood siding and trim is the most labour intensive substrate because it needs the most preparation. Scraping, sanding, filling, spot priming, and dealing with any rot found along the way. Older wood surfaces frequently have multiple layers of old paint in varying states of adhesion, and the extent of that is not fully knowable until the scraping starts.

Fiber cement is straightforward and holds paint extremely well, provided the joints and the cut ends are properly caulked and primed.

Brick and masonry need masonry appropriate coatings, and painting brick is close to irreversible, which is a decision worth making carefully rather than as part of a color scheme.

Height and access

Two stories is more than twice the work of one, not because there is twice the surface but because everything takes longer. Ladders have to be set and reset, materials carried up, and safety measures taken. Anything requiring scaffolding rather than ladders adds meaningfully.

Access difficulties are their own multiplier. A wall two feet from a fence, a section over a sloping bank or a roof, dense planting against the house, and steep site grades all slow the work. So does anything that requires masking large areas of hardscape or protecting a pool.

Preparation, which is where the real difference lives

This is the section to read most carefully, because it is where a low bid gets low.

Full preparation on an exterior repaint includes washing the entire surface to remove dust, chalk, mildew and pollution film, scraping every area of failed coating back to sound material, sanding the transitions so no ridge shows through the new paint, filling and repairing damaged wood, replacing any rot rather than painting over it, caulking every joint that should be sealed, and spot priming every bare area before the finish coats go on.

A crew doing all of that spends more days on preparation than on painting. A crew that skips it can wash quickly, scrape the worst of it and start spraying on the second morning. Both houses look identical when the trucks leave. One of them looks identical in eight years and the other is peeling in two.

The specific questions that separate them are worth asking outright. How is the surface being cleaned, and is it pressure washing or hand washing. What is the standard for scraping, and what happens to edges. Is bare wood being primed, and with what. Is caulking included, and which joints. What happens if rot is found, and how is it charged.

Materials, and the honest version of the paint question

Paint quality does matter, and the difference between a builder grade exterior product and a premium one is real, in the resins that determine flexibility and adhesion and in the pigment load that determines color retention. On a sun exposed elevation in a climate with intense summer ultraviolet, the difference shows within a few years.

But the material is a modest share of the total cost. Upgrading to a premium product across a whole house adds a small amount relative to the labour, and it is almost always the right call. A quote that saves money by using cheaper paint is saving in the wrong place.

Coats matter too. Two finish coats over a primed surface is the standard for a color change or a weathered surface. One coat is appropriate only for a fresh, sound surface in the same color, and even then it is marginal. A quote should state the number of coats explicitly.

Repairs, and why they are frequently excluded

Most exterior quotes exclude carpentry, or include a fixed allowance for it, because the extent of rot behind old paint genuinely cannot be established until the surface is opened up. That is reasonable. What is not reasonable is a quote that is silent on the question, because that is the one that produces an argument on day three.

Look for a stated hourly or unit rate for repair work and an agreement that anything beyond a threshold is discussed before it is done.

Where the price is actually decided

The realistic drivers, in order of how much they move the number: total paintable surface, the amount and difficulty of preparation, height and access, substrate condition, and finally the paint itself.

That ordering is why anyone comparing two very different quotes needs to compare scope rather than headline price. Ask each bidder for the same specific inclusions and the gap frequently closes considerably, and where it does not, the reason is usually visible in the preparation section.

Timing and other levers

Booking outside peak season helps in most markets. Painters are busiest in the dry warm months and quieter in winter, and a flexible schedule can be worth a real discount.

Reducing scope deliberately is more effective than negotiating rate. Painting the body and leaving sound trim, or doing three elevations this year and the fourth next year, are legitimate ways to fit a budget without buying a worse job.

Doing your own preparation is possible for the willing, but it is the part that decides the outcome, so it is a strange thing to take on if the goal is quality. Clearing plants, moving furniture, and taking down shutters and light fixtures are genuinely useful contributions and they save billable hours.

What a comparable quote contains

Named product and finish for each element, the number of coats, an itemized list of what is included down to eaves and railings, a description of the preparation standard, a stated approach to repairs with a rate, a schedule with a start and a duration, proof of license and insurance, and a written warranty with a term.

Two quotes containing all of that can be compared honestly. Two quotes containing a price and a paragraph cannot, and the difference between them means nothing.

Somebody rings us most weeks with a version of the same sentence. The house is old, they have heard about lead paint, and they want to know whether that means the repaint is going to cost double. The honest answer is that nobody can tell them over the phone, including us, and that the point of testing is precisely to stop guessing on a question that has a real answer.

Here is what testing does and does not tell you, and what changes on a job when the result comes back one way or the other.

Age Gives You Odds, Not Facts

Lead was permitted in residential paint in this country until 1978. That is the whole basis of the rule of thumb, and as rules of thumb go it is a decent one. Pasadena’s housing stock skews old. Bungalow Heaven alone is several hundred houses built mostly between the 1900s and the 1930s, and the same era of construction runs through Madison Heights, Garfield Heights, Normandie Heights and the older parts of Altadena. If your house has plaster over lath rather than drywall, single glazed double hung sash, and rafter tails poking out under a deep overhang, it was almost certainly painted at least once with a product that contained lead.

What the date does not tell you is where. And where is the entire question.

We have tested two houses on the same block, built in the same year by what looks like the same builder, and got completely different pictures. The first had been stripped and re-sided during a 1990s remodel, so the body of the house came back clean while the original sash in the back bedrooms came back positive on the first pull. The second had never been touched below the top two coats, and everything from the fascia down was positive. Same age, same street, entirely different jobs, entirely different quotes.

There is also the case nobody expects, which is a house from the mid 1970s that reads clean because the builder had already switched products before the deadline. Assuming based on the year would have cost that owner money for prep they did not need.

What We Test, and Why Not Everything

We test the surfaces the work will disturb. That is a shorter list than the whole house and it is deliberately so.

The window sash and the jambs they run in. The door edges and the stops behind them. Porch rails, balusters and treads. The fascia and the rafter tails, because that is where a scraper is going to spend real time. Whichever elevation is actually failing, since that is the one being taken back. If we are doing interior trim, the baseboards and the casings.

What we do not do is test forty spots for the sake of a thick report. If a wall is sound and we are washing it and coating over it without disturbing the film, its history does not change what happens on site. Testing it would produce a number that makes no difference to the method or the price, and charging for that is padding.

A Positive Result Is Not a Demolition Order

This is the part that most needs saying plainly, because the word lands harder than the situation warrants.

Lead sitting in a paint film that is intact, stuck down, and not being rubbed against is not doing anything to anyone. Paint on a wall is not the exposure route. Dust is. Chips are. A film becomes a genuine problem when someone attacks it with an orbital sander, torches it off with a heat gun, blasts flaking paint into the soil beneath a window with a pressure washer, or leaves a sash to grind itself to powder in its track every time a child opens it.

So the recommendation on most older houses is not removal. It is stabilization. Take the loose and failing material off in a way that controls the debris, feather the edges so the repair does not read through the finish, prime what came bare, and put a sound coating over the top. That approach makes less dust than stripping does, it costs less, and on a Craftsman with original redwood siding it also keeps a surface that has been doing its job for a hundred years.

Stripping to bare wood has its place. A door that has lost all definition under fifteen layers, a window that will never run again without it. Those are targeted decisions on individual components, made deliberately, with the containment to match. It is not a default setting for a whole house.

What Changes on Site

When a surface tests positive, the method changes and so does the calendar. In practical terms:

Scraping runs wet. The surface is misted as we work so the material comes away as chips and slurry rather than as a cloud. It is slower and messier and it is the single most effective thing on the list.

The ground gets sheeted well past the drip line, seams taped and edges weighted. On a day with Santa Ana conditions coming off the San Gabriels we stop, because wind will take sheeting and debris down the street faster than anyone can pick it up, and a containment that has blown away is worse than no containment because everybody assumed it was working.

Sanders, where sanding cannot be avoided, run with a sealed vacuum attachment. A great deal of it gets done by hand instead, because a machine on a piece of trim makes more airborne material than the time saving is worth.

Open flame is out entirely and so is any heat gun setting that takes the film to the temperature where it starts to give off fumes. Torching old paint is fast, it is common, and it is the one method we will not use on these houses at any price.

Clean-up happens at the end of every day, not the end of the job. Sheeting folded inward on itself, debris bagged, bags off the property that evening. Before we hand an area back, sills, porch decks and hard surfaces get a wet wipe down, because the entire purpose of everything above is that nothing is left behind for somebody to walk through.

All of that is real labor and it is why the quote for a positive house is higher than the quote for a clean one. It is also why we would rather test than assume in either direction. Charging every pre-1978 house for contained prep it may not need is not caution, it is a markup.

Where to Spend First If the Budget Is Tight

Most people do not have an open budget, and if the house needs more than the money covers, the friction surfaces are where it should go.

A double hung sash rubs its jamb every time it moves. On an original window carrying eight layers, that contact makes dust, and the dust lands on the sill and on the floor under it, which is exactly where small hands and pets end up. Door edges do the same against their stops. Covered porch treads do it underfoot. Those are the surfaces where a stable, intact film matters most, and they are also the fussiest ones to do properly.

Making a sash work again is slow work. The parting bead has to be free rather than painted solid. The meeting rails need to close. The glazing putty usually needs attention, and sometimes a pane needs re-bedding. Then it has to be primed and finished so that the two halves are not glued to each other by the first humid morning. It is the part of an old house repaint that gets quoted around and rushed most often, and it is the part that decides whether that room is still making dust next spring.

The elevations can wait a season. The sash usually should not.

The Other Half of the Job Is Just Painting

None of this replaces ordinary competence with a brush. Once the surface is stable you still have to pick the right primer for what you exposed, which is a bonding or alkyd primer on bare wood, a masonry primer on stucco, and a shellac based blocker on tannin bleed or a water stain. You still caulk every joint and butt end before the topcoat, because caulk is what keeps the next rain out from behind the finish. You still put on two coats over a color change, and you still work around the shade rather than painting into a hot west wall at four in the afternoon.

In Pasadena the south and west elevations take the whole UV load and fail years before the shaded sides do. That is the normal pattern and it is worth knowing before somebody tells you the whole house is due.

If your house predates 1978 and you are thinking about a repaint, start with a test rather than a color chart. Call (626) 566-4947 and we will come out, look at what the paint is doing, test what needs testing, and put the prep scope in writing before anybody talks you into a shade of green.
