If you own a larger home in Brentwood, you may be wondering which painting project to tackle first and what each will cost. Interior and exterior painting are often priced very differently, and for good reasons. This guide compares them side by side, with ranges by home size, so you can plan a budget that makes sense.
For the broader picture of hiring in Brentwood, including HOAs and crew size for larger homes, see our guide to house painters in Brentwood. This post focuses just on cost comparisons.
| Home size | Interior repaint | Exterior repaint |
|---|---|---|
| 2,500 to 3,000 sq ft | $3,000 to $5,500 | $4,000 to $7,500 |
| 3,000 to 4,000 sq ft | $3,500 to $7,000 | $6,000 to $9,500 |
| 4,000 to 5,500 sq ft | $5,500 to $10,000 | $8,500 to $15,000 |
| Single room, interior | $400 to $750 | Not applicable |
These ranges assume sound surfaces, standard prep and quality products. The exterior range is wider because roofline complexity, height and mixed materials matter more than square footage.
A useful rule of thumb is to compare projects by what each dollar buys. Exterior work protects the building envelope and sets the first impression, which matters for resale and neighborhood standards. Interior work changes how the home feels every day, and it is the part your family and guests actually live with. Most Brentwood homeowners end up doing both over a few years, and the right question is not which is better but which should come first and how to pay for them without stretching the budget.
Interior cost tracks wall and ceiling area and room count, so it grows roughly in line with square footage. Exterior cost tracks the surface you can see from outside, which depends on stories, gables and how much of the exterior is stone or brick versus paintable siding. A 4,500 square foot home that is mostly stone may cost less to repaint outside than a 3,500 square foot home that is all siding with detailed trim.
For a room-by-room view of interior pricing, see our interior painting cost guide.
Our exterior painting cost guide explains how exterior prices are built, with siding-type adjustments that apply across Middle Tennessee.
| Interior | Exterior | |
|---|---|---|
| Main benefit | Daily enjoyment, updated look | Protection and curb appeal |
| Best for selling | Neutral, bright rooms photograph well | First impression and online photos |
| Urgency | Low, cosmetic | Higher if paint is failing |
| Lifespan | 7 to 10 years in normal use | 7 to 12 years with good prep |
If paint is peeling or wood is exposed, exterior comes first because water damage gets expensive fast. If the exterior is sound and you are preparing to sell or just tired of dated interiors, a targeted interior refresh often gives the most visible improvement per dollar.
Many Brentwood neighborhoods require architectural approval for exterior colors, and some have preferred palettes. Approval itself is usually free, but it can add two to four weeks to your timeline, and a rejected color means redoing sample boards. Build the time into your plan and start the application before you schedule a painter.
A painter who has worked in your community can often suggest palettes that pass HOA review on the first try, which saves time and avoids paying to re-prepare samples.
Finish level is the quiet multiplier in Brentwood estimates. A standard repaint with a quality mid-tier paint costs far less than one that uses premium product lines, extra coats, specialty sheens or detailed color work on trim and millwork. On a large home the gap between a standard and a premium specification can be several thousand dollars, even when the square footage is identical.
Ask for the specification in writing, so you know exactly which level each quote represents. Comparing a standard quote to a premium one without noticing is the most common way homeowners overpay or under-buy.
The cheapest painting project is the one you do before problems spread. A small amount of trim repair and re-caulking every few years protects an exterior far better than waiting for a full failure, and fresh interior paint in high-traffic areas can be touched up between full repaints. A good painter will walk your home and tell you honestly what can wait and what cannot, instead of selling the biggest scope available.
Plan exterior work for spring or fall, and use winter for interior projects when crews are less busy. That scheduling flexibility, combined with a bundled contract, is often where the largest savings on a big Brentwood project come from.
A Brentwood family with a 4,000 square foot brick and siding home wanted to know whether to repaint the inside or outside first. The exterior had some peeling on south-facing trim, and the interior was a dated beige throughout.
| Project | Quote | Timing |
|---|---|---|
| Exterior: wash, trim repair, two coats siding and trim | $8,200 | October |
| Interior: main floor, stairs, hallways | $5,600 | January |
| Bundle discount, both under one contract | $700 off | Phased |
They did the exterior first because of the peeling trim, and scheduled the interior for winter when the crew had openings. The combined cost was $13,100 and the family saw a clear difference both from the street and inside. They also chose colors for the whole house at once, so the interior palette complemented the new exterior.
The takeaway is that interior and exterior are not competitors for the same dollars. They are different projects with different urgency, and a phased plan lets you do both without strain. Whatever order you choose, get the scope, product and schedule in writing, and compare quotes by specification rather than by total, since two Brentwood quotes for the same house can reflect very different levels of finish and prep.
ProPainting Murfreesboro prices interior and exterior separately and together, scaled to your home's size and trim. We serve Brentwood, Franklin, Murfreesboro and all of Middle Tennessee.
For comparable homes, exterior painting usually costs the same or somewhat more than a full interior repaint, because of height, prep and materials. Costs vary widely with home size and trim.
Roughly $5,500 to $10,000 for a full interior and $8,500 to $15,000 for the exterior, depending on condition, trim detail, ceiling height and finish level.
Do whatever is failing first. If both are planned, do the exterior first so dust and ladder work do not affect fresh interior paint.
Approval is usually free but can add weeks to the schedule, and rejected colors can require new samples. Start the application early.
Often 5 to 15 percent. Ask for separate and bundled quotes so you can see the savings and phase the work.
