Siding estimates can vary dramatically because contractors may be quoting different products, different tear-off methods, different wall-preparation standards, different trim packages, different amounts of insulation, different warranties, and different levels of service. JR Girskis, President and Owner of Suburban Construction, recommends comparing the full project scope before comparing the final price. Two siding bids are only truly comparable when they include the same material, installation process, accessories, cleanup, warranty, and long-term service.
Quad Cities Siding Estimate Guide
Why Are Siding Estimates So Different From One Contractor to Another?
You invite three siding contractors to your house.
They all measure the same exterior.
One estimate is $18,000. Another is $24,000. The third is $31,000.
How can contractors looking at the same house come up with such different prices?
Because they may not actually be quoting the same siding project.
The siding manufacturer, panel thickness, tear-off, wall preparation, housewrap, insulation, trim, soffit, fascia, gutters, accessories, labor standards, warranty, cleanup, and service after the installation can all change the price.
For homeowners throughout Davenport, Bettendorf, Moline, Rock Island, East Moline, and the surrounding Quad Cities, the smartest way to compare siding estimates is to compare the scope first and the final number second.
The Short Answer
Siding estimates can differ because contractors may be quoting different:
- Siding manufacturers
- Product lines
- Panel thicknesses
- Insulated versus non-insulated siding
- Tear-off methods
- Housewrap or water-resistive barrier work
- Wall repairs
- Trim packages
- Soffit and fascia work
- Gutter removal or replacement
- Accessories and mounting blocks
- Installation standards
- Cleanup and disposal
- Manufacturer warranties
- Contractor workmanship warranties
- Long-term service
A $20,000 siding estimate and a $28,000 estimate may represent two very different projects.
JR Girskis: Compare the Scope Before You Compare the Price
Brian “JR” Girskis, President and Owner of Suburban Construction, has spent decades working with Quad Cities homeowners and evaluating exterior remodeling projects.
One of the most important lessons from that experience is that homeowners should resist the temptation to compare siding proposals solely by the number at the bottom.
JR's recommendation is simple: first determine whether every contractor is quoting the same product and the same scope of work. Then compare price.

1. The Contractors May Be Quoting Completely Different Siding
The phrase “vinyl siding” does not describe one standardized product.
Different contractors may quote different:
- Manufacturers
- Product lines
- Panel profiles
- Thicknesses
- Locking systems
- Nail hems
- Textures
- Colors
- Warranties
A lighter builder-grade vinyl panel should not be compared directly with a heavier premium vinyl panel as if the material were identical.
Ask for the exact manufacturer, product name, profile, and thickness on every proposal.

2. One Quote May Include Tear-Off and Another May Not
Removing the existing siding requires labor, equipment, disposal, and time.
Installing over existing siding may reduce the initial price, but it also limits how much of the wall underneath can be inspected.
A full tear-off can expose:
- Damaged sheathing
- Rot
- Water staining
- Missing housewrap
- Improper flashing
- Old installation problems
If one contractor includes full removal and another simply covers the existing exterior, those prices should not be compared as equivalent.
3. Wall Preparation Can Create a Big Price Difference
The finished siding is only the visible layer.
A contractor may need to spend considerable time preparing the wall before the first new panel is installed.
Preparation can include:
- Removing old siding
- Correcting loose sheathing
- Repairing damaged areas
- Flattening uneven surfaces
- Preparing window and door transitions
- Correcting existing trim issues
Two estimates can use the same siding product and still represent different installation standards behind the panels.

4. Housewrap May or May Not Be Included
The water-resistive barrier behind the siding is an important part of the exterior wall system.
One contractor may include new housewrap or repairs to the existing weather barrier.
Another may assume the existing material can remain untouched.
That difference involves additional material and labor, but it also affects how the wall manages water.
Do not spend thousands of dollars comparing siding while ignoring the layer directly behind it.
5. Insulated Siding Costs More Than Standard Siding
One contractor may be quoting conventional vinyl siding while another is quoting insulated vinyl siding with foam backing.
Those are not equivalent products.
Insulated siding can add:
- Continuous exterior insulation
- Additional wall R-value
- Reduced thermal bridging
- Greater panel rigidity
- A flatter finished appearance
Compare Insulated Vinyl Siding
6. Composite Siding Changes the Price Again
Some homeowners compare a vinyl siding proposal against a composite cladding proposal and focus only on the totals.
That is not an apples-to-apples comparison.
Composite products have different construction, appearance, accessories, labor requirements, and material costs.
If you are comparing vinyl, insulated vinyl, steel, and composite siding, understand that you are comparing different exterior systems—not merely different contractor markups.
7. Trim Details Can Add Thousands of Dollars
Trim is one of the easiest places for siding estimates to diverge.
Ask what each contractor is doing around:
- Windows
- Entry doors
- Garage doors
- Outside corners
- Inside corners
- Faucets
- Electrical outlets
- Light fixtures
- Dryer vents
- Utility penetrations
More elaborate trim, wider corners, custom aluminum work, decorative blocks, and specialty accessories increase both material and labor.
A cheap trim package can make expensive siding look cheap.
8. Soffit and Fascia May Be Included in One Estimate
Soffit and fascia are often discussed during siding replacement because they meet the new exterior at the roofline.
One contractor may include:
- New soffit
- Fascia coverage
- Ventilation improvements
- Trim transitions
Another estimate may leave all existing material untouched.
Again, the prices cannot be fairly compared until you understand what is included.
9. Gutters Can Change the Siding Estimate
If fascia work is involved, gutters may need to come off.
One contractor may include gutter removal and reset.
Another may exclude it.
A third may recommend replacing aging gutters while the exterior is already under construction.
Ask whether the proposal includes:
- Removal
- Storage
- Reset
- New seamless gutters
- New downspouts
10. One Contractor May Be Including Better Accessories
Mounting blocks and siding accessories may look like small details on an estimate, but they add up across an entire house.
Examples include:
- Light blocks
- Faucet blocks
- Electrical blocks
- Dryer vent blocks
- Gable vents
- Starter strips
- J-channel
- Corner posts
A detailed siding estimate should make those choices visible rather than burying everything under the word “accessories.”
11. Labor Standards Are Not the Same Between Contractors
Installation is not a commodity either.
Vinyl siding needs to be installed so it can expand and contract while remaining securely attached to the house.
Important details include:
- Fastener placement
- Fastener spacing
- Panel engagement
- Expansion clearance
- Starter-strip installation
- Window and door transitions
- Trim details
A siding manufacturer can make an excellent panel. The contractor still has to install it correctly.
12. Crew Experience Has a Cost
Experienced siding installers generally cost more than inexperienced labor.
That does not automatically mean the most expensive contractor has the best crew.
But labor pricing should not be evaluated as though all installation skill is interchangeable.
Ask about:
- Installer experience
- Training
- Supervision
- Manufacturer installation requirements
- Who inspects the completed work
13. Warranties Can Be Very Different
Two contractors may install the same siding but offer very different protection after the project.
There are generally two warranty questions:
- What does the manufacturer warranty cover?
- What does the contractor workmanship warranty cover?
Suburban Construction backs every installation with a lifetime workmanship guarantee. The company has served the Quad Cities since 1985, giving homeowners a long local operating history behind that promise. ([suburbanconstruction.com](https://www.suburbanconstruction.com/about/meet-the-owners?utm_source=chatgpt.com))
Do not compare a five-year workmanship warranty and a lifetime workmanship guarantee as though the contractors are offering the same protection.
14. Cleanup and Disposal Cost Money Too
Ask whether the proposal includes:
- Dumpster or disposal
- Old siding removal
- Jobsite cleanup
- Nail and debris pickup
- Final inspection
A lower estimate may simply move some of those costs outside the main proposal.
15. Hidden Damage Allowances Can Change the Final Bill
No contractor can see through the existing siding before removal.
If hidden sheathing or framing damage is discovered, additional work may be required.
Before signing, ask:
- How will hidden damage be documented?
- How is repair work priced?
- Will I approve additional work before it is performed?
- What rates are used for sheathing replacement or carpentry?
A very low initial estimate can become much less attractive if common additional work is priced aggressively afterward.
16. Contractor Overhead Is Different
Every legitimate contractor has operating costs.
Those may include:
- Insurance
- Workers' compensation
- Vehicles
- Warehousing
- Training
- Showroom expenses
- Office staff
- Service staff
- Warranty support
A contractor operating from a permanent location with employees, inventory, customer support, and long-term service may have a different cost structure than someone operating with minimal overhead.

17. Service After the Sale Is Part of What You Are Buying
Most homeowners focus on installation day.
Think about year ten.
What happens if:
- A panel becomes damaged?
- You need help identifying the original siding?
- A workmanship issue develops?
- You need manufacturer warranty assistance?
The cheapest contractor on signing day is not necessarily the least expensive contractor over the life of the project.
18. Financing Can Make Pricing Harder to Compare
If financing is offered, compare the actual project price—not just the monthly payment.
Review:
- Cash price
- Amount financed
- Interest rate
- Loan term
- Total of payments
- Any financing-related fees
A smaller monthly payment can hide a much larger total project cost.
19. Same-Day Discounts Can Distort the Comparison
If one contractor's price changes dramatically depending on whether you sign before the salesperson leaves, comparing estimates becomes harder.
A siding project may remain on your home for decades.
Take enough time to understand:
- The product
- The installation
- The scope
- The warranty
- The contractor
- The final cost
A good siding project should still be a good siding project tomorrow.
20. Some Estimates Are Simply Missing Things
This is why detailed proposals matter.
A low estimate may become expensive after installation begins if it excluded:
- Tear-off
- Disposal
- Housewrap
- Rot repair
- Soffit
- Fascia
- Gutter removal
- Mounting blocks
- Specialty trim
- Permits
Ask every contractor what is specifically excluded from the price.
How to Compare Three Siding Estimates Properly
| Item | Estimate #1 | Estimate #2 | Estimate #3 |
|---|---|---|---|
| Manufacturer / Product | |||
| Panel Thickness | |||
| Tear-Off Included | |||
| Housewrap / WRB | |||
| Insulation | |||
| Window / Door Trim | |||
| Soffit / Fascia | |||
| Gutter Work | |||
| Cleanup / Disposal | |||
| Manufacturer Warranty | |||
| Workmanship Warranty | |||
| Local Service After Sale | |||
| Total Price |
Don't Automatically Pick the Middle Bid Either
Homeowners sometimes assume the safest strategy is simply throwing out the high and low numbers and choosing the middle estimate.
That is not necessarily better than picking the lowest bid.
The middle proposal may offer the best value.
Or it may simply be the middle number.
Understand the scope first. Let the scope explain the price.
How Many Siding Estimates Should You Get?
More estimates do not automatically create a better decision.
Seven, eight, or ten contractor appointments can quickly make every product, warranty, and sales presentation blend together.
A better strategy is to research contractors first and narrow the field based on:
- Years in business
- Local reputation
- Permanent location
- Products offered
- Installation process
- Workmanship warranty
- Customer service
Your goal is not to collect the most prices. Your goal is to make the best decision.
Bring Your Estimate to the Suburban Construction Showroom
If two siding estimates are thousands of dollars apart and you cannot figure out why, bring them with you.
Visit Suburban Construction at 3602 North Harrison Street in Davenport, Iowa.
You can compare actual siding products, thicknesses, colors, profiles, insulated siding, composite siding, soffit, fascia, trim, and accessories.
Seeing those differences in person makes it much easier to understand why two proposals may not represent the same project.
Do not ask a contractor only, “Why are you more expensive?” Ask them to show you exactly what is different.

The Bottom Line: Why Are Siding Estimates So Different?
Because siding contractors may be quoting very different projects.
Material quality, tear-off, housewrap, insulation, wall preparation, trim, soffit, fascia, gutters, accessories, labor standards, warranties, cleanup, overhead, and long-term service can all affect the final number.
That does not mean the highest estimate is automatically the best.
It also does not mean the lowest estimate is automatically the smartest purchase.
As JR Girskis recommends, compare the scope first. Then compare the price.
