Old paint that is cracking, alligatoring, or failing in sheets cannot be painted over. It has to come off first, and paint stripping can quietly become the single largest line item on an exterior repaint quote. In 2026, removal pricing in the US runs $1.50 to $8.00 per square foot depending on the method, the substrate, and whether the existing coating contains lead.
Across 13,611 exterior simulations we ran on US homes in the last year, about 8% of properties showed paint failure severe enough that a contractor would refuse to repaint without a full strip first. Strip pricing sits on top of, not inside of, the figures in our exterior house painting cost 2026 guide.

When Stripping Is Actually Required (And When It Is Not)
Most homes do not need a full strip. A pressure wash, scrape, sand, and prime cycle handles the majority of repaints. Stripping becomes mandatory in a narrow set of conditions:
- Adhesion failure on more than 25% of the surface. If you can lift paint with a fingernail or a putty knife across a quarter of the wall, a new coat will not bond to the old layers.
- Lead paint in homes built before 1978. EPA Renovation, Repair and Painting (RRP) rules trigger automatically and a certified firm must handle disturbance of more than 6 square feet interior or 20 square feet exterior.
- Going back to bare wood for stain. Solid stains and clear finishes require a clean substrate.
- Severe alligatoring or checking. Multi-layer cracking telegraphs through any topcoat within months.
- Repainting historic millwork. Decorative profiles lose definition under each repaint; stripping restores the original shadow lines.
Field Note
We tested Dumond Smart Strip Pro on a 4 by 4 foot panel of a 1928 Boston colonial last spring. Six layers of paint, including a lead-positive 1940s coat, lifted in a single 12-hour dwell. Total residential time including containment was just under 12 hours for the single panel, which is a useful sanity check on any per square foot pro quote.
The 4 Main Paint Stripping Methods Compared
Each method has a sweet spot. Match the method to the substrate, the number of paint layers, and the lead status before you price the job.
| Method | Best For | 2026 Cost / sq ft | Speed |
|---|---|---|---|
| Chemical strippers | Detailed wood, lead paint | $1.50 to $3.50 | Slow (3 to 24 hr dwell) |
| Heat guns / infrared | Flat clapboard, no lead | $2.00 to $4.00 | Medium |
| Sandblasting / media blasting | Masonry, brick, metal | $4.00 to $8.00 | Fast |
| Scrapers and sanding | Spot repairs, DIY | $1.50 to $3.00 | Slow |
1. Chemical Strippers ($1.50 to $3.50 / sq ft)
Chemical strippers dominate residential exterior work because they are quiet, non-igniting, and lead-safe when paired with proper containment. Three products own the US market in 2026:
- Citristrip ($28 to $34 per quart). Citrus-based, low odor, methylene-chloride free. Best for two or three paint layers on detailed wood. Dwell time 30 minutes to 24 hours.
- Dumond Smart Strip Pro ($95 to $115 per gallon). Soy-based, EPA Safer Choice listed, lead-paint approved when used with the company laminated paper. Removes 10-plus layers in one pass.
- Klean-Strip Premium ($45 to $55 per gallon). Faster acting (15 to 60 minutes) but harsher and not lead-cert approved. Best for clean-room shop work, not exposed exterior siding.
Pros charge $1.50 to $3.50 per square foot for chemical stripping on wood siding. The lower end assumes single-story access and two paint layers. Add $0.50 to $1.50 per square foot for lead-safe containment, plus disposal of contaminated waste.
2. Heat Guns and Infrared Plates ($2.00 to $4.00 / sq ft)
Heat softens paint so it can be scraped off in long ribbons. Two tools dominate:
- Speedheater Cobra and Silent Paint Remover infrared plates ($475 to $750 retail). Operate at 380 to 575 degrees Fahrenheit, well below the 850 degree lead-vaporization threshold. Slow but EPA-compliant on lead.
- Conventional heat guns ($45 to $180). Operate at 750 to 1,200 degrees, which is too hot for lead paint and triggers fume hazards. Use only on confirmed lead-free surfaces.
Heat methods are faster than chemicals on flat clapboard and produce no liquid waste. Pro pricing lands $2.00 to $4.00 per square foot, with infrared at the high end because the equipment investment is higher.
3. Sandblasting and Media Blasting ($4.00 to $8.00 / sq ft)
Media blasting is the only practical strip method for masonry, brick, stone, or metal. Modern crews use soft media (crushed glass, baking soda, walnut shells, or dustless vapor abrasive) instead of silica sand, which is banned for paint removal under OSHA silica rules.
Expect $4.00 to $8.00 per square foot. The high end reflects EPA RRP lead containment, scaffold rental on multi-story work, and disposal of spent media that may be classified as hazardous waste. Never blast wood siding for full strip work, the grain raises permanently.
4. Scrapers and Sanding ($1.50 to $3.00 / sq ft)
Carbide pull scrapers (Bahco 625, ProScraper) plus 80-grit sanders handle most spot strip work. This is the default approach when only 25% to 60% of the surface needs removal. Pros bill it as part of prep at $1.50 to $3.00 per square foot. Sanding lead paint dry without HEPA shrouded tools is an EPA RRP violation; budget $250 to $500 per day for a Festool CT 36 HEPA vacuum system rental.
Lead Paint and the EPA RRP Premium
If your home was built before 1978, federal law assumes lead paint until proven otherwise. The EPA Renovation, Repair and Painting Rule (40 CFR Part 745) requires that anyone paid to disturb more than 20 square feet of exterior painted surface must:
- Be an EPA Lead-Safe Certified Firm (firm certification fee $300 every 5 years).
- Have at least one EPA Certified Renovator on site (8-hour course, $215 to $295).
- Use lead-safe work practices: containment, dust minimization, HEPA cleanup, post-work verification.
- Provide the EPA "Renovate Right" pamphlet to the homeowner before work starts.
The practical cost premium for EPA RRP compliance on a stripping job is $1,200 to $4,500 per project, or roughly $0.75 to $2.00 per square foot above the base method cost. Civil penalties for non-compliance run up to $41,093 per violation per day in 2026 (the EPA-published figure, indexed annually for inflation).
Lead Paint Trigger Test
Pre-1978 home + exterior surface area to be disturbed greater than 20 sq ft = EPA RRP applies. There is no DIY exemption when you hire a contractor. Owner-occupied DIY is exempt from RRP firm certification but still subject to state and local lead-paint laws (notably Massachusetts, Maryland, Rhode Island, Vermont, and New Jersey).
DIY vs Pro: The Real Math on Paint Stripping
A 1,500 sq ft exterior strip job is at the outer limit of what a determined DIY homeowner can complete in 2026. Here is the side-by-side on a representative 1,500 sq ft two-story wood-sided home with two paint layers, no lead.
| Line Item | DIY | Professional |
|---|---|---|
| Chemical stripper (Smart Strip, 12 gal) | $1,260 | Included |
| Scrapers, brushes, plastic sheeting | $240 | Included |
| Scaffold or ladder rental (2 weeks) | $420 | Included |
| PPE (respirator cartridges, Tyvek, gloves) | $180 | Included |
| Disposal (non-hazardous) | $140 | Included |
| Labor (80 to 120 hr DIY) | $0 (your time) | $3,200 to $4,800 |
| Total | $2,240 + your time | $3,200 to $4,800 |
DIY breaks even at roughly $1,000 of saved labor, but only if the project is single-story, lead-free, and you can spare two full weekends. Add lead paint or two-story heights and the calculation tilts sharply toward hiring a certified pro. For the full repaint side of the equation, our DIY vs professional exterior painting cost breakdown applies the same math to the painting phase.
Disposal: Why Lead Waste Costs Three Times More
Paint waste is one of the most regulated home renovation byproducts in the US. Three categories drive 2026 disposal pricing:
- Non-lead solvent or oil-based residue. Goes to a household hazardous waste collection site or a paint-recycler under the PaintCare program ($0 to $50 per project in the 11 PaintCare states).
- Latex paint chips and dried stripper waste. Most states classify as solid waste; allow normal trash disposal once fully dried. Some California counties require certified facilities ($120 to $260 per cubic yard).
- Lead-positive scrapings and contaminated PPE. Classified as hazardous waste under RCRA Subtitle C. Must go to a permitted Treatment, Storage, and Disposal Facility (TSDF). 2026 pricing runs $400 to $1,200 per 55-gallon drum, plus $250 to $600 transportation per pickup.
A small dumpster from a service like Dumpsters.com can handle non-lead exterior strip waste at $375 to $625 per 10-yard unit, but the rental contract will require a signed declaration that no lead paint, asbestos, or universal waste is included.
Cost by Home Size and Substrate (2026 Snapshot)
| Home Size | Wood (chemical) | Brick / Stucco (blasting) | Lead-positive premium |
|---|---|---|---|
| Small (800 sq ft surface) | $1,200 to $2,800 | $3,200 to $6,400 | +$900 to $2,000 |
| Medium (1,500 sq ft surface) | $2,250 to $5,250 | $6,000 to $12,000 | +$1,200 to $3,000 |
| Large (2,500 sq ft surface) | $3,750 to $8,750 | $10,000 to $20,000 | +$1,800 to $4,500 |
These ranges hold for most US metros. Pricing pressure is highest in Northeast cities with concentrated pre-1978 housing stock. Our Buffalo NY exterior painting cost guide and Detroit MI exterior painting cost guide walk through local lead premiums for two cities where more than 70% of housing predates 1978.
Hiring the Right Contractor: 6 Questions to Ask
- Is your firm EPA Lead-Safe Certified? Ask for the firm certification number and verify on the EPA RRP locator.
- Which stripping method do you recommend, and why? A pro who only knows one method may be the wrong fit for your substrate.
- How will you contain dust and waste? Look for 6-mil plastic, HEPA vacuums, and clear disposal logs.
- What is the per-square-foot price, including disposal? Get a flat number, not a daily rate.
- What is your warranty on the prep and primer system? One to three years on prep is typical.
- Can I see a recent comparable project? A photo of a home with the same siding type, age, and number of stories tells you more than testimonials.
After Stripping: What Comes Next
Bare wood, masonry, or metal cannot stay exposed. UV and moisture damage start within 7 to 14 days. Apply a stain-blocking primer such as Zinsser Cover-Stain or Sherwin-Williams Multi-Purpose Latex within two weeks of stripping. Then plan two finish coats per the 2026 complete exterior paint cost guide. If your project includes interior surfaces too, our whole-house painting cost guide bundles strip, prime, and finish into a single budget. For more inspiration on what colors hold up best post-strip, HGTV's popular exterior paint colors guide walks through palettes that read well on freshly-stripped wood and brick.

Frequently Asked Questions
1. Is it always cheaper to paint over old paint than to strip it?
On a square-foot basis, painting over is roughly half the cost of stripping. But paint applied over a failed substrate will fail again within 2 to 4 years, which means a full repaint at $3,500 to $7,500 inside the warranty window. Strip-and-repaint runs more upfront but lasts 12 to 15 years with quality acrylic finishes.
2. Can I strip paint myself if I am pretty sure there is no lead?
Yes, if your home was built in 1978 or later, DIY strip work is unrestricted federally. Always wear an N100 respirator, eye protection, and chemical-resistant gloves, and contain runoff with plastic sheeting. Pre-1978 owner-occupants are exempt from EPA RRP firm rules but should still test paint chips with a 3M LeadCheck swab ($14) before starting.
3. How long does chemical stripper need to dwell?
Dwell time depends on the product and paint layers. Citristrip: 30 minutes to 24 hours. Smart Strip Pro: 3 to 24 hours. Klean-Strip Premium: 15 to 60 minutes. More layers, thicker coats, and cooler weather all extend dwell. Test a small section before committing to a full panel.
4. Can I sandblast wood siding?
Conventional sandblasting raises wood grain and gouges softer growth rings within seconds. Soft media blasting (baking soda, walnut shells, dustless vapor abrasive) can be done on wood at very low pressure (35 to 45 PSI), but the surface still needs heavy sanding afterward. For most wood, chemical or infrared methods produce a better post-strip finish.
5. What is the EPA RRP rule and does it apply to me?
The EPA Renovation, Repair and Painting Rule (40 CFR Part 745) requires lead-safe work practices when paid contractors disturb more than 20 sq ft of exterior or 6 sq ft of interior painted surface in housing built before 1978. It applies to all paid renovation work, including stripping. Owner-occupied DIY is exempt federally, though several states (MA, MD, RI, VT, NJ) impose their own lead-safe requirements on DIY too.
6. How do I dispose of lead paint scrapings legally?
Bag scrapings in double 6-mil contractor bags, label them as "lead-containing waste," and arrange transport to a permitted hazardous-waste TSDF. Your state environmental agency maintains a current list of approved facilities. Expect $400 to $1,200 per 55-gallon drum plus pickup fees in 2026. Never mix lead waste with regular construction debris in a curbside roll-off.
7. Does stripping damage historic siding?
Done correctly, stripping restores rather than damages historic millwork. Chemical strippers preserve original tool marks, decorative profiles, and shadow lines that disappear under each layer of repaint. Avoid heat methods on resin-rich woods like pine, which can scorch, and avoid blasting on softwood altogether. Historic-property tax credits often require documented stripping rather than overcoating.
8. How long does a full exterior strip take?
A two-person professional crew strips roughly 200 to 350 sq ft per day on wood with chemical methods, or 400 to 700 sq ft per day with infrared. A typical 1,500 sq ft surface strip plus prep runs 5 to 10 working days. Add 2 to 4 days for lead containment setup and teardown. DIY single-person timing typically doubles those numbers.
Bottom Line: 2026 Paint Stripping Cost Cheat Sheet
- Method choice drives 60% of cost. Chemical and scraping at $1.50 to $3.50; heat at $2.00 to $4.00; blasting at $4.00 to $8.00.
- Lead paint adds $0.75 to $2.00 per sq ft. Pre-1978 homes trigger EPA RRP, certified firms only.
- Disposal is non-trivial. Non-lead waste is roll-off friendly; lead waste is hazardous-waste-only at $400 to $1,200 per drum.
- DIY breaks even at $1,000 of saved labor. Best on single-story, lead-free, two-paint-layer homes.
- Always test the new color first. Upload a photo to our free AI preview before you commit to the strip.
