A homeowner's guide to siding replacement in the Triangle

What new siding costs in Raleigh, Durham, Cary and Chapel Hill, how the materials compare, when North Carolina requires a license or a permit, and the state code rules that keep water out of the wall behind the siding. It also covers the lead paint rules for houses built before 1978. Every rule and price links to the page it came from.

What siding replacement costs in the Triangle

The figures below come from Angi's local cost figures and from national cost guides. They are guide figures. The size of your house, the material and what is found under the old siding set the real price, so get written quotes for your own house.

Local figures

Angi's local range for a siding job runs from $5,420 to $15,240 in Raleigh and Cary, $7,055 to $16,953 in Durham, and $6,993 to $16,888 in Chapel Hill (Angi, Raleigh; Angi, Cary; Angi, Durham; Angi, Chapel Hill). Raleigh and Cary return identical figures, so read them as one regional number.

National guides

• Angi (updated October 9, 2026): about $11,590 on average, with most projects between $5,559 and $17,728 for materials and installation (Angi). Vinyl or engineered wood runs $3 to $12 per square foot, and premium materials can pass $30 (Angi).
• HomeGuide (October 29, 2025): $4 to $13 per square foot installed, or $10,000 to $32,500 for a 2,500-square-foot home (HomeGuide).
• Fixr (updated January 23, 2026): $14,500 on average for a 2,000-square-foot home, with most homeowners spending $8,500 to $20,000 (Fixr).
• HomeAdvisor (updated June 20, 2026) gives the same $5,559 to $17,728 range as Angi, and says removing and replacing siding takes seven to 14 days (HomeAdvisor).

By material

The lifespans are HomeGuide's national estimates (HomeGuide). This guide found no Triangle-specific data on how long each material lasts here.

What adds to the price

Angi says to budget $150 to $1,500 for old siding removal and permits, depending on location, and to expect surprises: "hidden water damage, rot, or structural repairs that may be uncovered once the old siding is removed" (Angi). Labor alone runs about $1 to $4 per square foot (Angi). Ask each bidder how they will price rotten sheathing or framing found during the job, before you sign.

Licenses: who may install siding in North Carolina

North Carolina requires a general contractor license only when a job costs $40,000 or more (G.S. 87-1; NC contractor board). Most siding jobs come in below that. At $40,000 or more, the license class that covers houses is the Residential classification, which covers "all construction and demolition activity pertaining to the construction of residential units" built to the state's residential code (NC contractor board, classes). Any licensee can be looked up on the board's public search (License search).

Lead paint on houses built before 1978

Painted siding on a house built before 1978 brings in a separate state certification, whatever the price. North Carolina requires certification for paid renovation that disturbs lead-based paint in housing built before 1978 (NC lead program), and the firm you hire "must be a North Carolina certified renovation firm" (NC lead FAQ). The federal rule's exemption for minor repair stops at 20 square feet of painted surface outside (40 CFR 745.83), and taking off the siding of a whole house disturbs far more than that.

Before work starts, the firm must give you the EPA pamphlet "The Lead-Safe Certified Guide to Renovate Right," and you can check a firm's certification in the state's public database (NC lead FAQ; NC lead program).

Permits in Raleigh, Durham, Cary and Chapel Hill

The state rule

State law says no building permit is needed for work "costing forty thousand dollars ($40,000) or less" on a single-family home unless it falls under one of the listed exceptions (G.S. 160D-1110). The first exception is load-bearing work, and the same sentence then exempts "replacement of windows, doors, exterior siding" (G.S. 160D-1110). So under state law, re-siding a house for $40,000 or less needs no permit, as long as the work is done to the state code (G.S. 160D-1110). If rotten wall framing has to be replaced, that is usually load-bearing work, and it needs a permit.

Raleigh

Raleigh lists "siding, windows, doors" among the projects that require a permit but no plans (Raleigh, how to get a permit). Its residential permits page says work costing $40,000 or less can still need a permit when it involves load-bearing structures (Raleigh, residential permits). Neither page explains how the list fits with the state carve-out for siding, so ask the City before you count on skipping a permit.

Durham

Durham's City-County Building & Safety Department says a building permit is "required for any project that includes load bearing work or any project exceeding $40K in market value" (Durham Building & Safety). The page does not mention siding.

Cary

Cary's no-permit list covers "non-structural cosmetic building elements" and roof coverings with the same materials, and does not name siding (Cary, permits). Ask Cary's permits office if you are unsure; its page invites the question (Cary, permits).

Chapel Hill

Chapel Hill's residential permits page says "any building, construction, alteration, remodeling work with structural components requires a building permit," and does not mention siding (Chapel Hill, permits).

Historic districts

In a local historic district, new siding needs its own approval. Raleigh requires a Certificate of Appropriateness from the Raleigh Historic Development Commission for homes in a historic district or designated as a landmark (Raleigh, how to get a permit). Durham lists "Replacement of siding, doors, or windows" among the changes that can need one, whether or not the change can be seen from the street (Durham COA). Ask the town's preservation staff before you choose a material.

The short answer

Re-siding for $40,000 or less needs no permit under state law (G.S. 160D-1110). Raleigh lists siding as permit work anyway (Raleigh, how to get a permit), and Durham, Cary and Chapel Hill do not name it (Durham Building & Safety; Cary, permits; Chapel Hill, permits). Structural repairs found during the job need a permit everywhere. North Carolina's Attorney General warns that a builder who asks you to take out the permits yourself may not be licensed (NC Attorney General).

State code rules for new siding

The 2018 North Carolina codes are the ones in effect (State Fire Marshal, codes). Most of the code's rules for siding are about keeping water out of the wall behind it (NC Residential Code, ch. 7).

The water barrier and drainage

The code wants a water-resistant barrier behind the siding and "a means of draining to the exterior water that enters the assembly" (NC Residential Code, ch. 7). The minimum barrier is one layer of No. 15 asphalt felt, or another approved water-resistive barrier, over the studs or sheathing of every exterior wall (NC Residential Code, ch. 7). It is lapped at least 2 inches where an upper course covers a lower one, and at least 6 inches at joints (NC Residential Code, ch. 7). When the old siding comes off, ask the crew to show you the barrier before the new siding goes on.

Flashing

Flashing has to be installed "shingle-fashion" to keep water out of the wall and off the framing (NC Residential Code, ch. 7). The code names the places that need it, including window and door openings, where a porch, deck or stairs attach to the house, and where a wall meets a roof (NC Residential Code, ch. 7). Ask which of these your house has and how each will be flashed.

Vinyl siding

Vinyl siding must be certified and labeled as meeting ASTM D3679, and it must be installed following the manufacturer's instructions (NC Residential Code, ch. 7). Ask for the product name, so you can check its label and its installation guide.

Fiber cement siding

Fiber-cement lap siding must meet ASTM C1186, be lapped at least 1 1/4 inches, and have its end joints protected with caulk, an H-shaped joint cover or a strip of flashing behind the joint (NC Residential Code, ch. 7).

Wind

Siding, its backing and its fasteners have to resist the design wind load for the house (NC Residential Code, ch. 7). Wake, Durham, Orange and Chatham counties are not on the state's county wind list, so they fall under "counties not listed" at 115 mph; neighboring Johnston and Harnett are at 120 (NC Residential Code, ch. 3).

Wood close to the ground

Wood siding and sheathing less than 6 inches from the ground must be naturally decay-resistant wood or preservative-treated wood (NC Residential Code, ch. 3). If your new siding will run close to the soil or mulch, ask what the bottom course is made of.

Hiring: questions to ask and red flags

• Was the house built before 1978? If so, ask for the firm's North Carolina renovation certification and check it in the state database (NC lead program; NC lead FAQ).
• Ask what water barrier goes behind the siding, and how windows, doors, decks and roof lines will be flashed (NC Residential Code, ch. 7).
• Ask for the exact product, and for the maker's installation instructions the crew will follow (NC Residential Code, ch. 7).
• Get a written price for rot repair found under the old siding before work starts (Angi).
• Ask who handles any permit or historic-district approval. A builder who wants you to pull the permit yourself may not be licensed (NC Attorney General).
• A demand for everything up front or cash only is a warning sign (FTC).
• If you sign at home, the FTC's Cooling-Off Rule gives you until midnight of the third business day to cancel many sales, even when you invited the salesperson (FTC Cooling-Off Rule).
