A strata council in Burnaby got three quotes for the same building envelope renovation. The lowest came in at $480,000. The highest at $890,000. Same building, same scope, same site walkthrough.
That gap is not unusual. We see it every month. The strata renovation contractor BC market is one of the most quote-spread segments in construction, and most council members never find out why until the project is already a year late or $200,000 over budget.
Ten years of strata work teaches you to read these quotes a different way. The cheapest one is almost never the right one, and the most expensive one is not always padded.
## The 40% spread, explained
A strata renovation is not a simple line item. Three contractors looking at the same building can each price five different things and call all of them “envelope renovation.”
One quotes a coat of paint and minor crack repair. Cheap. Fast. Wrong.
Another quotes full rainscreen rebuild with new sheathing, drainage, paper, and stucco over rainscreen. Expensive. Slow. Right for a 1990s leaky condo era building.
The third quotes something in between, with disclaimers in fine print about what gets pulled apart only after demolition reveals the actual substrate condition.
The cheapest quote almost always assumes the substrate is fine. The most expensive almost always assumes it is not. The truth is usually somewhere between, but you cannot know until walls open up.
This is the first source of variance: scope assumption.
## Where the variance lives
After scope, the next big variance is detailing at penetrations. Every window, deck ledger, hose bib, dryer vent, and pipe sleeve is a place where water can enter the wall. A contractor who flashes every penetration with new pan flashings, head flashings, and self-adhered membrane is doing work the cheaper contractor is not. The detailing labor on a 50-unit building is real money. We have seen $80,000 quote differences hinge on this line item alone.
Then rainscreen depth. BC code requires a drainage cavity behind cladding for stucco and most modern claddings. Cavity depth ranges from 10mm strapping to 19mm strapping or more. The deeper cavity dries faster. The shallower one is cheaper to install. Contractors hide this in the spec sheet.
Then warranty terms. A contractor offering a 2-year workmanship warranty is structurally different from one offering 10 years. The 10-year contractor priced in the cost of coming back to fix something six years from now. The 2-year contractor did not.
Insurance and bonding. WCB clearance, builder’s risk insurance, performance bonds, and labor and material bonds add 3 to 6% to a quote. Strata councils are usually required to confirm these per their bylaws. Quotes from contractors who skip the bond cost less and put the strata corporation directly at risk if the contractor fails mid-project.
Project management overhead for occupied buildings. Strata buildings have residents living through the work. Phasing around occupants, daily site cleanups, controlled noise hours, balcony access coordination, these are real labor lines. Some contractors price them. Some bury them. Some never price them and run into trouble at month four when residents start filing complaints.
Mobilization and access. Scaffolding cost on a 6-story building can run $40,000 to $90,000 depending on duration and complexity. Swing stage versus tube and clamp versus mast climbers all price differently. Quote A and Quote B can differ by $50,000 on access strategy alone.
Add these up and you arrive at the 40% spread without anyone padding their margins.
## The mistake councils make
Strata councils almost always pick the middle quote.
It feels safe. Not the cheapest, not the most expensive, must be reasonable. This logic is wrong roughly half the time, because the middle quote is often a cheap quote with a bit of padding from a contractor who is hoping to make it up later in change orders.
The right quote is the one that aligns with the scope your building actually needs. That is a different question than “which one falls in the middle.”
We have inherited too many half-finished projects where the original middle-quote contractor disappeared at month six. The strata then hires a second contractor at premium rates to finish what the first one started. The total cost ends up 60% above the highest original quote.
## How to make quotes apples-to-apples
Before signing anything, run every quote through this filter. We do this for free for any strata council that asks.
Scope match. Side-by-side, line by line, what is each contractor including? Sheathing replacement allowance? Window flashing details? Trim replacement? Painting? Sealants? If three quotes do not list the same items, they are not comparable. Ask each contractor to revise to a uniform scope.
Allowance levels. Most strata renovations have allowances for unknown conditions. Sheathing replacement allowance might be 10% in one quote and 30% in another. Demand identical allowance percentages so the bottom-line comparison is fair.
Substrate testing. A contractor who has done test cuts and moisture readings on your building before quoting has more accurate numbers than one who eyeballed the exterior. Ask if test cuts were performed.
Reference projects. Three projects of similar scope, completed in the last three years, with strata council references you can call. If a contractor cannot produce this, they are not strata-experienced.
Schedule realism. A contractor promising to complete a 50-unit envelope rebuild in four months in BC weather is either dreaming or planning to leave the work unfinished. Ask for a Gantt chart or a detailed schedule with weather contingency.
## BC-specific factors that move quotes
Depreciation reports under the BC Strata Property Act now drive most renovation timing. If your depreciation report flagged building envelope concerns at year 25, lenders, insurers, and prospective buyers all know. Contractors price knowing the strata is under pressure to move, which sometimes tightens schedules and sometimes inflates bids.
Step Code is starting to apply to major renovations in some BC municipalities. If your renovation triggers a Step Code threshold, insulation upgrades become part of scope. That adds $20 to $40 per square foot and changes the assembly. Ask each contractor whether Step Code applies to your project.
Leaky condo era buildings. Anything constructed in BC between 1985 and 2000 has a higher probability of envelope failure than buildings before or after. Quotes for these should assume substrate damage until proven otherwise. A contractor quoting clean substrate on a 1992 condo without test cuts is not being honest with you.
Coastal exposure. A building two blocks from English Bay sees more weather than one in central Burnaby. Contractors who have not worked this gradient often underprice the coastal job.
## Why MV Construction does this work
Ten years on Lower Mainland strata exteriors. WCB-covered crews, fully licensed, insured, and bonded. We carry builder’s risk and performance bonds on every strata project. References available from councils we have worked with on rebuilds ranging from 18 to 240 units.
Every quote we issue is itemized line by line. Every penetration detail is named. Every allowance is named with a percentage. Councils that compare our quote against two others side by side usually find that our middle-of-the-pack pricing actually bought more scope than the cheaper option.
## What to do next
If your strata is collecting quotes for an envelope or full exterior renovation, send us all three quotes you already have. We will review them at no charge and produce a one-page comparison showing where the variance lives. You decide what to do with that.
