Ask three siding contractors to price the same colonial in Troy and you may get three very different numbers. That doesn’t mean anyone is cheating you. Siding jobs vary more than most people expect, because so much of the work is in the details you can’t see from the street. This guide explains what drives the price, so you can read an estimate with confidence. We don’t publish price ranges, because they go out of date and every house is different; a contractor who has measured your home is the only one who can give you a real number.
How siding is priced
Contractors measure walls in squares, where one square is 100 square feet of wall. They add a waste factor for cuts around windows, doors and gables, then price the siding, the labor, the trim and accessories, and the tear-off and disposal. Trim work, including window and door surrounds, corner posts, soffit and fascia, is often priced separately by the linear foot.
| Cost driver | Why it changes the price |
|---|---|
| Wall area (squares) | More wall means more material and labor |
| Number of stories | Second- and third-story walls need ladders, staging or lifts |
| Material and grade | Standard vinyl, premium vinyl, insulated vinyl, fiber cement and engineered wood all differ |
| Tear-off | Removing aluminum, wood or old vinyl adds labor and dumpster fees |
| Sheathing repairs | Rot or missing sheathing found during tear-off must be fixed |
| Openings | Each window and door needs flashing, J-channel or trim |
| Trim, soffit and fascia | Wrapping or replacing trim adds labor and material |
| House shape | Gables, dormers, bump-outs and bays mean more cuts and waste |
| Access | Tight lots, decks, landscaping and steep yards slow the work |
| Season and schedule | Busy seasons and post-storm demand affect availability |
Material choice is the biggest lever
Material changes the price more than anything else you control. Standard vinyl is the most economical; premium and insulated vinyl cost more but stay straighter and resist cold-weather cracking better. Fiber cement costs more for both material and labor because it’s heavy, needs careful cutting and is usually painted. Our guides to vinyl siding and fiber cement compare them in detail.
The hidden part: what’s behind the old siding
Many Oakland County homes have siding over siding: aluminum over wood, vinyl over aluminum. Until it comes off, nobody knows exactly what’s underneath. That’s why good estimates include a unit price for sheathing repairs, so you know in advance what each replaced sheet will cost if rot turns up. It protects you from surprise change orders, and it protects the contractor from guessing.
House wrap, window flashing, kick-out flashing and new soffit vents aren’t glamorous, but they’re what keep a wall dry. Make sure every estimate says whether they’re included.

- Manufacturer and workmanship warranties in writing
- Michigan license number and proof of insurance
Ways to keep the cost reasonable
Get estimates outside the busiest weeks if you can. Combine siding with trim and gutter work so you pay for setup once. Choose a mid-grade product that suits the house rather than the most expensive line. And fix problems like clogged gutters and failed caulk early, so a repair job doesn’t turn into a replacement. Finally, remember that the cheapest estimate isn’t always the lowest cost over time. Siding that’s installed with proper wrap and flashing and a sensible product grade will need fewer repairs, hold its color longer and add more to the home’s value when you sell.
