How to Compare Siding Quotes in BC Without Getting Burned

Three quotes for the same house, spread so widely they seem to describe different planets: every Lower Mainland homeowner who has priced a re-side knows the moment. The instinct is to average, or to suspect the high one of greed and the low one of corner-cutting, and both instincts misread what is actually on the pages. Quotes diverge because scopes diverge, and the skill of comparing them, which this guide teaches, is the skill of making scopes comparable before letting prices compete. It extends our siding guide for BC buildings and pairs with how to choose a siding contractor: that guide picks the people, this one reads their paperwork.

Why quotes genuinely differ

Start generously: most quote spread is not villainy, it is unshared assumptions. One contractor assumed your existing weather barrier is serviceable; another priced replacing it. One saw your pre-rainscreen era house and priced building the cavity; another priced boards-for-boards. One carries disposal at Metro Vancouver's real transfer rates; another lumps it into a number that will grow later. One prices James Hardie by name; another prices "fiber cement," which may mean anything, and one priced the trim package your elevation drawings imply while another priced the minimum.

Each assumption is defensible alone. Unstated, together, they produce quotes that cannot be compared, and homeowners comparing them anyway are choosing between fictions. The fix is not more quotes; it is normalization.

The normalization method

Take your quotes and build the comparison table yourself, or make each bidder help. The rows that matter, drawn from the nine cost factors every legitimate quote is built from:

Scope of removal: full tear-off to sheathing, or over-clad? Disposal included, at what assumption? Any quote proposing installation over existing cladding is describing a different project entirely, and our wall-drying science guide explains why we decline that project.

The assembly: weather-resistive barrier, replaced or assumed? Rainscreen strapping, included or absent? Flashing scope at openings, named or waved at? This cluster is where the quality of your next thirty years lives, and where low bids most often got low.

Hidden damage handling: the rot question. Explicit unit pricing with photo documentation, a stated allowance, or silence? Silence is not zero; it is a decision deferred to the moment you have least leverage, mid-project with your walls open.

Product, by name: manufacturer, line, profile, finish. "Or equivalent" is a flag to resolve now, not at delivery. Factory finish versus site paint changes both price and decades, per the ColorPlus math.

The labour picture: who installs, employees or a subcontracted unknown, and what documentation habits come with them, stage photos, foreman checks, the practices that make installation quality inspectable.

The paper: deposit and draw schedule, workmanship warranty in years and terms, manufacturer warranty compliance, WorkSafeBC and liability coverage, and, where scope triggers it, the permit question answered rather than ignored.

An hour with that table converts three incomparable numbers into a real decision, and it routinely reorders the bids: the "expensive" quote that included the assembly is suddenly the value, and the cheap one is cheap the way a car without brakes is.

Reading the darker patterns

Most contractors quote honestly. The patterns below are the minority worth recognizing on sight. The mobilization special: a price valid only if you sign today, urgency is a sales tool, not a construction constraint, and real quotes survive a week of thought. The front-loaded draw schedule: most of the money before most of the work, which inverts your leverage exactly when discoveries might need negotiating. The vague allowance: "contingency as required" with no unit pricing, a blank cheque wearing a scope's clothing. The scope written thin: two lines for a whole-house re-side, everything else "as discussed," memories of discussions do not survive disputes; paper does. And the quote that will not name its product or its crew. None of these is illegal; all of them shift risk quietly toward you, and pricing that risk back into the comparison is exactly what the normalization table does.

The five questions that separate bids

Ask each bidder the same five, and take notes. What happens behind the boards on my house, specifically? (Fluency here predicts everything.) How do you handle what tear-off reveals, and can I see an example of how you documented it on a past job? What would you cut from this quote if I needed the price lower, and what would you refuse to cut? (The refusal list is the integrity test; the right answers include the assembly and the flashing.) Who exactly is on my wall, and who checks their work? What does your warranty cover in year six, not year one? The answers convert paper into people, and they surface the difference between a price and a practice. We answer all five before clients ask, in the quote document itself, because a bid that anticipates scrutiny is telling you how the project will run.

Weighing price against everything else

With scopes normalized and questions answered, the final weighing is honest arithmetic plus honest self-knowledge. Arithmetic: the spread between bids, divided by the decades the wall will serve, is usually small money per year, and the items that created the spread, assembly, documentation, warranty, are precisely the ones that determine whether those decades arrive. Self-knowledge: your tolerance for risk and for project management. The lowest normalized bid with thin practices is a project you will be managing; the fuller bid is one you will be watching. Some owners happily trade oversight labour for dollars; most, in our experience, only think they will enjoy it until the first rainy week with walls open.

And one genuinely underrated tiebreaker: responsiveness during quoting predicts responsiveness during warranty. The bidder who took two weeks to answer a scope question will take longer when the question is a callback.

A worked comparison: three real-shaped bids

Abstractions land better with numbers-shaped stories, so here is a composite from our estimating files, three bids for the same 1980s Coquitlam two-storey, spread wide enough to alarm its owners. Bid A, the low one, priced "siding replacement, fiber cement" in four lines: no tear-off language, no barrier scope, product unnamed, rot unmentioned, one-third deposit. Bid B, mid-range, itemized tear-off and disposal, named the product line, priced rainscreen strapping, and carried rot as "if found, discussed on site," no units. Bid C, the high one, itemized everything B did plus barrier replacement, flashing scope by opening count, unit-priced rot repair with photo documentation, stage photography, and a five-year workmanship warranty in the contract body. Normalized, the mystery dissolved: A was not cheaper, it was smaller, a different project wearing the same address; B and C described the same wall with different risk allocations, and C's premium over B, divided across the decades the wall would serve, amounted to insurance priced below its value. The owners chose C, then used A's number in exactly the right way: as a reminder of what silence costs. The pattern repeats weekly across the region, and the table, not the gut, is what reads it.

After you choose: making the quote the contract

Comparison's last step is conversion: the winning quote becomes the working agreement, and three habits protect the transition. First, merge the answers in: everything clarified during the five questions, crew identity, rot units, stage-photo commitment, gets written into the contract text or an addendum, per the paper-beats-memory rule, because the quote that won on practices should bind on them. Second, fix the change mechanism: how discoveries get priced, documented and approved mid-project, photo, unit price, written sign-off before proceeding, so the tear-off surprises that are normal on older homes arrive into a process rather than a negotiation. Third, align the payment schedule to milestones you can see: deposit at signing sized to materials, draws at visible stages, tear-off complete, assembly reviewed, cladding per elevation, holdback at walkthrough, the structure that keeps everyone's incentives pointed at completion. A contractor comfortable with all three conversions is confirming everything the comparison suggested; resistance at this stage is the last exit before commitment, and worth taking seriously precisely because it is cheap now and expensive later.

Common questions while comparing

"Two bidders disagree about what my wall needs. Who is right?" Often both are describing defensible approaches to an unknown, which is why evidence beats debate: ask each to explain what they observed and what they assume, and where the disagreement is about hidden conditions, the investigation-first method settles it better than argument. A small exploratory opening costs less than choosing wrong.

"Is it rude to share one quote with another contractor?" Sharing scope details to normalize comparisons is fair and common; asking someone to simply undercut a number invites exactly the corner-cutting this guide warns about. Compare scopes openly, let pricing follow.

"How much should the deposit be?" Enough to secure materials, not enough to fund someone else's project. Deposits sized to real procurement, with draws following visible milestones, are the healthy pattern, and front-loaded schedules deserve direct questions.

"What if the lowest bidder is a friend or family?" The comparison table gets more important, not less, precisely because the relationship makes mid-project disagreements harder. Put the scope, the change process and the warranty in writing exactly as you would with a stranger, and the friendship survives the project.

What we put in our own quotes, and why

Since this guide asks a lot of bidders, fairness requires showing our own paper. A Mega Siding quote states: the measured scope by elevation, tear-off and disposal explicitly, the assembly work named layer by layer, barrier, strapping, flashings by opening, the product by manufacturer, line, profile and finish, hidden-damage handling with unit pricing and a photo-documentation commitment, access and staging, the crew and foreman, the schedule with weather buffers, the payment milestones, and the workmanship warranty terms in the document body rather than a brochure. Where scope triggers them, permit responsibilities appear too, with who files what.

We write them that way for a self-interested reason worth admitting: detailed quotes prevent the disputes that destroy projects and reputations. A homeowner who can see what they are buying does not discover it mid-project; a crew working to a written scope does not improvise; and a change that arrives with a unit price and a photograph is a decision rather than an argument. The documentation habits that run through everything we publish start here, on the page before the wall.

The corollary for readers comparing anyone's quotes: this level of detail is achievable, so its absence is a choice. Ask for it. Bidders who can produce it will; bidders who cannot have told you something useful.

The comparison in one page

Print this if it helps. Normalize six rows across every bid: removal and disposal, assembly layers, hidden-damage handling, product by name, crew and documentation, and paper (warranty, payments, permits). Ask five identical questions and note who is fluent. Divide any remaining spread by the decades the wall will serve. Then choose the bid whose refusal list, the things they will not cut, matches the things that actually keep water out.

Key takeaways

• Quote spread is scope spread: normalize removal, assembly, hidden-damage handling, product names, labour and paper before comparing any dollars.
• Silence is not savings: unmentioned rot handling, disposal or flashing scope is deferred cost with worse leverage attached.
• Five identical questions asked of every bidder expose the difference between a price and a practice.
• Divide bid spreads by decades of service before judging them large, and let the refusal list, what a contractor will not cut, reveal integrity.
• The quote that anticipates your scrutiny is the preview of the project that will not need it.

And a closing reassurance for owners who find this process intimidating: you do not need construction expertise to run it. Every step above is reading, asking and comparing, skills you already have. The contractors worth hiring will help you do it, because a client who understands what they bought is a client who stays satisfied through the project and recommends the crew afterward.
