How to start a siding business that sells well and installs clean

Siding is a trade where the sale can take a month and the install takes days. A homeowner looks at samples, argues with a spouse about colors, waits on an HOA or an insurance adjuster, and then expects your crew to strip the old cladding and re-side the house within the week without trampling the shrubs. Companies that last get good at both halves: measuring and selling carefully up front, and running a safe, tidy install after the contract is signed. This guide walks through the work, how licensing and certification usually work, insurance and bonds, equipment, a pricing approach, finding first customers through channels you own, and how the seasons change from one region to the next.

This is general information from people who also run service companies. Use it as a starting point, and get legal, tax and insurance questions answered by a professional where you work. Licensing and permit rules are set by states, counties and cities and they change, so confirm each point with the agency responsible for it.

What does a siding company actually do?

Residential siding revenue usually falls into five kinds of work:

• Full re-siding. Removing old vinyl, aluminum, wood or composite and putting up new cladding, typically with new house wrap, corners, trim and soffit. These are the largest tickets with the longest sales cycle.
• Repairs. Panels the wind pulled loose, a course cracked by a stone from the mower, woodpecker holes, a section that melted beside the grill. Small tickets and quick decisions, and a chance to meet an owner who may want the whole house re-sided later.
• Storm and insurance work. Wind and hail damage on a home with an open claim, which brings an adjuster, a written scope of loss and a slower payment schedule into the job.
• Soffit, fascia and trim. Wrapping rotted wood trim in aluminum coil, replacing vented soffit, and capping window and door casings, either with a siding job or on their own.
• New construction. Siding new homes and additions as a subcontractor to builders. The volume can be steady, but the builder controls the schedule and the payment terms, and you sell to one buyer instead of many homeowners.

Choose your materials early. Fiber cement, vinyl and insulated vinyl, engineered wood, metal and natural wood each call for different tools, cutting methods and fastening details, and each manufacturer publishes its own installation instructions. A crew that hangs vinyl well is not automatically ready for fiber cement, which is heavier, throws silica dust when cut, and comes primed for paint or with a factory finish. Consider starting with one material plus repair work, and add a second material after the crew has finished a number of houses.

Do you need a license to install siding?

Usually some license, registration or permit applies, and which one depends on where the house sits. According to the Small Business Administration's licensing page, your business activities and your location set which licenses and permits apply to you at the state, county and city level. Construction is on its list of activities often regulated locally. Siding contractors tend to meet one of these setups:

• A state contractor license that covers residential exterior work, sometimes with an exam, proof of experience or financial requirements.
• A home improvement license or registration aimed at work on existing homes.
• No state license for siding, but a city or county contractor registration and a permit for re-siding.
• Separate licenses for work you may add later, such as roofing, windows or anything electrical.

Maryland shows the home improvement model. The Maryland Home Improvement Commission says only MHIC licensed contractors may contract with homeowners for home improvement work, and its page on what counts as home improvement lists siding under exterior work. We will not summarize other states here because the rules differ and get amended. Begin at our state startup directory, read your state licensing agency's definitions and exemptions, and ask the local building department whether re-siding needs a permit and an inspection. If you plan to follow storms into other states, look up each state's licensing and door-to-door sales rules before your crew arrives.

Storm work brings insurance claims, and claim handling is regulated too. The Texas Department of Insurance says state law there prohibits acting as a public adjuster, or advertising to adjust claims, if you provide or may provide contracting services on the property. Photograph the damage, write your estimate and stay out of claim negotiation unless your own state's rules plainly allow it.

Which certifications should a siding installer get?

Three kinds of credentials come up for siding companies: a federal lead-safe requirement, an industry installer certification, and programs run by manufacturers.

EPA lead-safe certification. A house built before 1978 may have painted wood clapboard or painted trim under its current siding. According to the EPA's lead renovation (RRP) program page, certification applies when you are paid for a job that disturbs paint on a house, preschool or child care building put up before 1978, and it covers every firm, a one-person sole proprietorship included. Workers have to be certified renovators or be trained on the job by one. EPA runs the program in most of the country, and its page lists 15 jurisdictions authorized to run their own. The small-job exemption is narrow. The definitions in 40 CFR 745.83 cap exterior minor repair and maintenance at 20 square feet of disturbed paint, and they exclude any job that demolishes painted surfaces, so pulling off painted wood siding does not qualify however small the patch. The pamphlet rule in 40 CFR 745.84 applies too: within the 60 days before work begins, hand the owner EPA's lead pamphlet and collect a written acknowledgment, or mail it and keep a certificate of mailing dated 7 or more days before you start. Have the firm certified and a certified renovator on the crew before you sell your first older house.

VSI Certified Installer. The Polymeric Exterior Products Association runs the VSI Certified Installer Program for vinyl siding. Its page says you take a class from a VSI Certified Trainer, online or in person, then pass an exam on vinyl siding installation. Applicants need one year of industry experience, or two consecutive semesters of an approved installer curriculum at an accredited school, and the certification is valid for five years before recertification. For a new company, it is a concrete way to show homeowners that your installers learned the published method.

Manufacturer programs. Some manufacturers run contractor programs of their own. The James Hardie FAQ, for example, says members of its ALLIANCE program receive extensive training on installing its products and are licensed and insured. The same FAQ lists what it takes to join, including a state license, liability insurance of $1,000,000 per occurrence, workers' compensation insurance, a satisfactory credit report and a background check with at least six past clients, so plan to apply once you have finished houses and customers to point to. Ask the brands and supply houses you plan to buy from what their programs require and what they offer installers.

Old siding shingles. The EPA's asbestos overview lists roofing and siding shingles among the places asbestos may be found, and says exposure may occur only when the material is disturbed or damaged. When a house has old cement-type shingles, have the material tested before anyone cuts or pulls it, check your state's asbestos rules, and price abatement as its own line or hand it to a qualified abatement contractor.

What safety rules apply on a siding crew?

Once you hire, OSHA rules apply. Some states enforce them through their own OSHA-approved State Plans, which OSHA requires to be at least as effective as its own program. Three standards matter on most siding jobs:

• Scaffolds. Under 29 CFR 1926.451, fall protection is required for each employee working from a scaffold higher than 10 feet over a lower level, and erecting, moving, dismantling or altering it must happen under the supervision of a competent person qualified in that work.
• Pump jacks. Pump jack scaffolds are a siding staple, and 29 CFR 1926.452(j) sets rules for them: metal brackets with two positive gripping mechanisms, poles braced at the bottom, top and other points as needed, and no using the workbench as a scaffold platform.
• Silica. Cutting fiber cement makes respirable silica dust. Table 1 of OSHA's construction silica standard has an entry for handheld power saws with blades of 8 inches or less cutting fiber-cement board. It applies to outdoor cutting only and calls for a saw with a commercially available dust collection system whose dust collector delivers the tool maker's recommended air flow and has a filter of 99% or greater efficiency, with no respirator required. Cut indoors, or skip those controls, and the standard's exposure assessment rules apply instead. Employers it covers also need a written exposure control plan.

Put scaffold setup, bracing and dust collection time into every estimate. They are part of the job, and a crew that skips them to finish early puts the whole company at risk. Our job site safety basics covers training records and daily habits.

What insurance and bonds does a siding contractor need?

Tell your agent exactly what you do: wall heights, scaffolds and pump jacks, subcontracted crews, pre-1978 homes, and any roofing or window work, because each one changes the coverage conversation. The core policies:

• General liability. The NAIC's summary of commercial general liability includes injuries you cause to others and harm to property that isn't yours. On a siding job, think of a dropped panel through a window or a stray nail in a driveway tire, and ask your agent how the policy treats water damage after a tear-off.
• Workers' compensation. Required of employers in nearly every state, according to the NAIC. If you plan to use subcontracted install crews, how you classify them has tax and insurance consequences; our guide to employees vs independent contractors explains the tests.
• Commercial auto. Per the NAIC, a commercial auto policy may also extend to rented vehicles and to employees' own cars used for company business.
• Tools and equipment. Brakes, pump jacks and scaffold planks on a trailer are worth insuring separately.

Ask your licensing agency and city whether a license or permit bond is part of registering. Commercial and public projects may ask for bid, payment and performance bonds. The SBA surety bond program guarantees bid, performance and payment bonds for small businesses that qualify, on contracts worth as much as $9 million ($14 million when the contract is federal). The same page says SBA does not guarantee commercial bonds, the kind government agencies require so that a business follows laws and regulations. See our surety bonds guide and our contractor insurance guide for certificates and additional insured requests, and collect a certificate of insurance from every sub before they set foot on a job.

What equipment and vehicles does a siding company need?

Buy for the material and the jobs you can book this season. Rent lifts and extra scaffold until the schedule proves you need your own.

• A truck and a lockable enclosed trailer, plus a dump trailer or a dumpster rental for each tear-off.
• Extension ladders, ladder jacks, pump jacks with poles and planks, or frame scaffold for tall walls.
• Fall protection gear and the training to use it.
• A portable bending brake for aluminum trim coil, and coil stock in the colors you sell most.
• Vinyl tools: a siding removal (zip) tool, snap-lock punch, nail slot punch, tin snips and a saw blade suited to vinyl.
• Fiber cement tools: shears, and a saw with a dust collection system that meets the silica standard's Table 1 controls.
• Coil nailers, a compressor and hoses, levels, chalk lines and a long tape.
• A moisture meter for checking sheathing after tear-off.
• Plastic sheeting, tape and a HEPA vacuum for lead-safe jobs.
• Magnetic sweepers, every job, before the crew leaves the yard.

Material usually comes from a supply house or lumberyard and is delivered to the driveway. Open trade accounts early, ask about lead times and return terms on special-order colors, and keep a running list of what each crew uses per house. A missing box of outside corners can idle a crew for half a day.

How should a new siding company price jobs?

Before the first estimate, settle three things. First, your measuring method: a full re-side is quoted from a takeoff of every wall, and the panels are only one line of it, because trim, openings, tear-off and height setup each carry their own labor. Second, your contract terms: a per-sheet price for rotted sheathing found after tear-off, a deposit that covers special-order material, and how long the quote holds. Third, a repair minimum that pays for the truck, the ladder and the color hunt on a one-panel job. Our siding pricing guide works through a full estimate line by line, and how to price service jobs covers the labor burden and overhead math underneath it.

When you sign a re-siding contract at the homeowner's kitchen table, a federal rule comes with it. The FTC's guide to the Cooling-Off Rule explains that when a sale of $25 or more happens in the buyer's home, the buyer may cancel for a full refund through the third business day after the sale, up to midnight, and the seller has to explain that right when the sale is made and leave two copies of a cancellation form behind. Exceptions apply, and state home solicitation laws can pile on more requirements. Have a local attorney review your contract once, before the first signature, and consider waiting out the cancellation period before ordering a custom color.

How do you get your first siding customers?

Lead marketplaces sell home improvement requests, and a siding estimate is expensive to chase: an evening of measuring, samples, a written quote. Networx's help center says each lead on its pay-per-lead plan can reach up to 4 contractors in total. Angi's annual report for 2025 counts match fees from pros as revenue even when the pro never performs the requested service. Local Services Ads from Google bill by the valid lead, and Google's help page says lead prices vary with your location, the type of job and lead, and your bidding mode. Some owners use them to fill a first season. When the budget stops, so do the requests.

Channels you own keep producing after you stop paying for them:

• A website that sells the look. A page for each material you install, a repair page, a storm damage page, and a gallery of houses you have sided, labeled with the product color and the town. Our websites for contractors are built around those pages.
• A Google Business Profile with finished elevations in the photos, every service listed and your service area set.
• A phone that never goes to voicemail after a windstorm. At a new company the person who answers the phone is often the one on the pump jack. An AI receptionist picks up while you are on the wall, sends an exposed-sheathing call to you right away by your rules, and puts estimate requests into your calendar.
• Trades that see the walls first. Roofers, gutter and window installers, painters, home inspectors and listing agents all find damaged siding before the owner calls anyone. See partnerships with agents and property managers for ways to open those conversations.
• The street you just sided. With the owner's permission, a yard sign during the install and a short letter to nearby houses afterward.
• Your own records. A CRM that keeps elevation measurements, product line and color name on each address. Those records are your future repair work and your referral list.

See our page for siding contractors for the site pages, call rules and job records we set up in this trade.

How seasonal is siding work across the US?

• Northern states: the install season runs roughly spring through fall, and winter is for selling, measuring and booking. Vinyl can go up in the cold with adjustments; the PEPA installation manual calls for a 1/4 inch gap at corner posts and channels, widened to 3/8 inch when you install below 40°F. Caulk, sealant and paint for fiber cement have their own temperature limits printed on the label.
• Hail country: one storm can damage siding on every house in a subdivision, followed by weeks of inspections, claims and installs.
• Hurricane coasts: wind repairs and emergency covers bunch up around each storm, inside the Atlantic season that NOAA's National Hurricane Center sets at June 1 through November 30.
• Warm, dry regions: installs can run most of the year, with summer heat shortening crew hours.

Plan cash around your region's slow stretch (our seasonal cash flow guide shows the math). Use the quiet months to photograph finished houses, follow up on unsigned estimates and meet the roofers and inspectors who will send you spring work.

Trades next door to this one have their own guides: starting a roofing business and starting a painting business. Every guide in this series sits on the start a company hub.
