How to Compare Siding Replacement Quotes in the Lower Mainland

Two siding quotes can name the same product and still cover very different work. One may include removal, repairs behind the panels and new flashing; another may leave those items to be priced later. For Richmond and Lower Mainland homeowners, comparing the scope first makes the total price much more useful.

Before choosing a colour or accepting a proposal, ask each contractor to describe what will happen to the whole wall assembly. This checklist helps you identify missing details without needing to become a siding installer.

1. Confirm which walls and components are included

Start with a marked-up photograph or a written list of the elevations being worked on. Does the price cover the whole house, one wall, the garage or only damaged sections? Ask how the work will finish where new siding meets material that remains.

The product description should identify the manufacturer, product line, profile, finish and colour. Corner boards, window trim, starter pieces and other accessories should also be clear. “Supply and install siding” leaves too much room for different interpretations.

If you are comparing a repair with full replacement, request separate scopes. Ask about matching limitations: a new panel or fresh finish may look different beside weathered siding, even when the product name is the same.

2. Separate removal from repairs to the wall beneath

Ask whether the existing cladding will be removed and disposed of, and what can be assessed before that work starts. A surface inspection cannot establish the condition of every concealed section of sheathing or framing.

The quote should explain how unexpected damage will be handled. Useful questions include:

• Will the contractor provide photographs before covering the wall again?
• Which repairs are included, and which are additional?
• Are there agreed unit rates, allowances or a written change-order process?
• Who approves extra work, and how will any schedule change be communicated?

An allowance is a budget provision, not confirmation that every possible repair is covered. Ask what happens if the work exceeds it.

3. Ask how the wall will manage water

New siding is only one part of rain protection. BC Housing’s cladding maintenance bulletin explains that rainscreen walls use an outer cladding layer, a membrane behind it and an air space that supports drainage and drying. The visible finish does not tell you whether those concealed components are in good condition.

Ask the contractor to identify the existing wall arrangement and describe the proposed membrane and drainage details. If a rainscreen cavity is included, the scope should explain how it will be formed and how water will leave it. If components will be retained, ask what will be checked before they are covered.

This is a discussion about the proposed assembly, not a request for a generic promise that the wall will be “fully sealed.” Where the existing construction or moisture damage is complex, ask whether a building enclosure consultant should be involved.

4. Make flashing and transitions explicit

Windows, doors, vents, roof intersections and adjoining decks deserve specific attention. BC Housing’s rainscreen research highlights the importance of these connections: even a rainscreen wall can develop local moisture problems when details allow water to enter and remain trapped.

Ask which flashings will be replaced, which will remain and how they will connect with the wall membrane. Clarify responsibility for removing and reinstalling downspouts, lights, hose connections and other items attached to the wall. Any specialist work should be identified before construction starts.

For the selected siding, request installation to the applicable manufacturer instructions. James Hardie’s technical documentation library, for example, includes product installation and clearance guidance. The relevant details depend on the actual product and installation; a general internet diagram is not a substitute for that specification.

5. Compare finishing, access and cleanup

Make a separate list of items that can be easy to overlook:

• Scaffolding, lift access and protection of landscaping or nearby surfaces.
• Removal and reinstatement of attached components.
• Trim painting, cut-edge treatment and touch-ups where applicable.
• Fascia, soffit and gutter work: included, optional or excluded.
• Debris removal, final cleanup and a walkthrough.
• Payment stages, taxes, estimated timing and weather-related scheduling.

Ask how exposed work areas will be protected during construction. Get product warranty information and any installation warranty terms in writing, including exclusions and who to contact with a concern.

Common questions

Does the lowest quote automatically mean corners are being cut?

No. Access, scope and product choices can explain price differences. Ask contractors to resolve missing details before comparing totals. A lower price is easier to assess when you know exactly what it includes.

Should I replace my gutters at the same time?

Not automatically. Ask whether they need to come off for access and whether they can be reinstalled. Coordinate any planned gutter or fascia work so the responsibilities are clear. Our North Vancouver gutter replacement project shows an example of adjoining exterior components.
