Siding installation: a guide for pros
What customers ask, how to win the job, and what to put on your profile.
Offering siding installation
Siding installation is a full-wall project where the barrier, the flashing and the trim decide whether the new cladding keeps water out. Your win is a clear scope that covers the hidden layers, not only the panel line.
What customers ask
- What material is best for my climate and the way my walls face?
- Will the new siding stop water from getting into my walls?
- Do I have to remove the old siding?
- How will you handle the trim and the windows?
- What warranty do I get on the siding and on the labor?
- Does the old siding or paint have to be tested before it comes off?
How to win the job
- On the first call, ask which material they want, which walls show damage, and how old the house is, so you know what to check before you quote.
- Bring samples of the siding profile, the trim and the weather barrier to the visit, and show how the flashing goes at a window.
- Probe the old siding, trim and sheathing at a few points on the site visit, and photograph any moisture stains you find.
- Put the weather barrier, flashing, trim count, sheathing repair and fastener plan in the quote as separate lines, not hidden inside the siding line.
- Explain how the new siding is fastened and why the nailing matters for that material, in plain words the homeowner can follow.
- Agree on the removal and disposal plan in writing, including protection for landscaping and windows.
- Send a closeout packet with the product names, color codes, warranty papers and a photo log of the wall before the panels went on.
What to put on your profile
- Photos of finished siding jobs that show corners, trim, window flashing and roofline detail
- Siding materials you install, with the profiles and finishes available
- Whether you do sheathing repair, house wrap replacement and full trim packages
- Service area and whether you handle the full exterior, such as gutters and soffit, in one project
Follow-up that helps the customer
- Offer gutter and downspout work after siding, since the new cladding changes where water runs at the eave.
- Suggest a sealant and paint check on the trim after the first year, to keep joints in good condition.
- Recommend a soffit and fascia review if the old boards show rot once the siding is off.
Licenses and permits
Siding installation is commonly licensed exterior or general contractor work, and a permit is often required for a full exterior change. Check your state and local licensing and building office requirements before you bid.
Questions
Do I need a permit to re-side a house?
Often, yes, for a full exterior change. Confirm with the local building office and put the responsibility for the permit in the contract.
What if the old siding contains hazardous materials?
Test before you remove it, following the rules where the house is. Do not disturb suspect material without a plan for handling and disposal, and put the testing in the quote.
How do I handle rot found in the sheathing?
Stop, photograph the area, and send a priced change order. Repair the sheathing and flashing before the new siding goes on.
