A siding company is part sales organization, part construction company. Full replacements are large, considered purchases with long decision cycles, and the margin on each one depends on measuring accurately, ordering the right material, and handling surprises behind the old siding fairly. Repairs and storm work keep cash moving between the big jobs.
How a siding business makes money
Full replacements. The core revenue for most siding companies. Large tickets, usually sold through an in-home estimate, often with financing.
Repairs. Damaged panels, storm damage, and small sections. Lower tickets, but quick to sell and a source of future replacement leads. Color and profile matching is the hard part.
Storm and insurance work. Hail and wind damage bring bursts of demand. Insurance work requires careful documentation, and the rules on what a contractor may do in a claim differ by state, so check yours before you take it on.
Trim, soffit and fascia. Often sold with siding, sometimes on their own. Pairs naturally with gutter work; see the gutter hub.
Many siding companies also sell roofing or windows. The roofing hub covers the roofing side.
Running the day
Siding work splits between the office and sales side and the production side.
On the sales side, speed matters. Respond to new leads within minutes, book the estimate, and follow up on a schedule after the proposal goes out. A homeowner collecting three quotes will often pick the contractor who explained the options clearly and stayed in touch.
On the production side, the sequence is materials, then crew. Confirm the delivery date before you lock in the crew start date, and coordinate the dumpster. During the job, photograph progress, and document any change order in writing with photos before the work is done.
Crews working on ladders, lifts and scaffolding need fall protection and setup time built into the schedule. OSHA publishes guidance on fall protection.
Pricing your work
- Measure carefully. Walls in squares, openings, inside and outside corners, starter, J-channel and trim in linear feet. Use the same method every time, or use measurement reports.
- Apply a waste factor based on the home's complexity, then refine it from your own job data.
- Price materials by line. Siding, trim, soffit, fascia, house wrap, fasteners and accessories, each at your cost plus markup.
- Price labor per square from your installer or subcontractor cost, plus supervision.
- Add tear-off, disposal and permits as their own lines.
- Add overhead and margin. Remember a 40% margin needs about a 67% markup. The markup and margin calculator helps, and the labor rate calculator sets your in-house labor rate.
- Offer options, such as vinyl and fiber cement, or siding only and siding with new trim and soffit. See good, better, best estimates.
The siding estimate template shows a square-based replacement estimate. In TradesWork, proposals with material options show a monthly payment for each, which helps on large replacement tickets.
Marketing that works for siding contractors
Fast lead response. Most siding leads come from search, referrals and lead services. The first contractor to respond and book an appointment has an advantage.
Job site presence. Yard signs and neighbor postcards around active jobs generate local leads, especially in neighborhoods with homes of similar age.
Before-and-after photos. Exterior work photographs well. Use real job photos on your website and Google Business Profile.
Reviews and referrals. Large purchases lean heavily on reviews. Ask every customer, and reward referrals.
Storm response. After a storm, being organized and honest about documentation matters more than being first.
Managing materials and crews
Material mistakes are the most common margin leak in siding. Three habits help. First, have someone other than the salesperson check the takeoff before ordering on larger jobs. Second, confirm color, profile and quantities with the supplier in writing, and check the delivery against the order before the crew starts. Third, track leftover and returned material on every job, so your waste factor reflects reality.
If you use subcontracted installers, put scope, quality standards, cleanup expectations and pay per square in a written agreement, and verify their insurance. Schedule them only after material delivery is confirmed.
Choosing software
For a siding contractor, consider:
- Lead management and follow-up for long sales cycles.
- Proposals with options, financing display and e-signature.
- Measurement integration if you rely on aerial reports.
- Job costing that compares estimated and actual material and labor.
- Crew and subcontractor scheduling for multi-day jobs.
- Photo documentation for change orders and insurance work.
Exterior-focused CRMs such as AccuLynx and JobNimbus are common for replacement-heavy companies; Jobber and Projul are used by smaller and multi-trade shops. TradesWork fits lead response, option proposals, multi-day crew jobs, photos, payment and job profit reporting today. It does not connect to measurement services, financing lenders or supplier ordering yet, so replacement-heavy companies that depend on those should weigh it. The software buyer's guide can help structure the comparison.
