Siding Contractor Software in California

Siding jobs don't fit neatly in generic contractor software. You've got full wraps, partial replacements, color matching trim, and HOAs that take three weeks to approve a sample. ExteriorPro lets you bid by square footage, track what material's going on what elevation, keep the approval paperwork attached to the project, and hand the crew a clean scope on install day. No more rebuilding the estimate from memory because the customer changed the J-channel color.

Whether it's a full wrap in California suburbs or a partial replacement after hail, ExteriorPro keeps the scope, the material by elevation, and the install week on one screen.

California's siding market is stucco first, and everything else second. The stucco tract house from the 1950s through the 1990s is the state's house, and the trade is patching it, re-coating it, and replacing the wood trim that the sun and the termites finish first. Fiber cement has most of the market where siding goes on, because it does not burn, does not rot, and takes the ultraviolet, and the fire code is now the reason it sells. In a fire hazard severity zone the exterior wall has to resist flame and embers, and since January 1, 2026 those rules sit in the state's new Wildland-Urban Interface Code. The Palisades and Eaton fires of January 7, 2025 destroyed 16,246 structures and killed 31 people. The Camp Fire of November 8, 2018 destroyed 18,804 structures in Paradise, and the rebuild there leans to fiber cement and stucco.

The contract law is strict. Any home improvement contract carries a down payment of no more than $1,000 or 10 percent of the price, whichever is less, in 12-point bold, and no payment for work not yet done. The homeowner has three business days to cancel, five at 65 or older, and seven business days for repair after a declared disaster. After an emergency, the price of repair services cannot rise more than 10 percent for 180 days. California has no deductible statute of its own, so siding on a claim runs on the general insurance fraud rules.

A siding company is licensed by the Contractors State License Board, with four years of experience, two exams, and a $25,000 bond, and since January 1, 2025 anything over $1,000 needs the license. Working without one is a misdemeanor. The salesperson registers with the board too.

The houses are the market. The median California house dates from 1976 and fewer than one in ten from before 1940, so the work is the stucco, the plywood, and the hardboard of the 1960s through 1980s in the San Fernando Valley, the Inland Empire, Sacramento, and the East Bay. Downtown Los Angeles gets about 14 inches of rain a year and Sacramento 18, so rot is a coastal and a Sierra problem, and sun is everyone's. The state lost about 54,000 people in the year to January 1, 2026 and still added 115,165 homes. The growth is in Mountain House, Lathrop, Menifee, Roseville, and Clovis.

Every trade, one price

Roofing, siding, windows, and gutters are all included at one price per location — so a crew that adds a second trade doesn't change what they pay.
