Three bids arrive for the same building. One is thin and cheap. One is thick and expensive. One sits in the middle. Boards and owners compare the totals first. The totals are the only figures that look comparable. They almost never are. Three contractors have priced three different jobs. Nothing on the cover page says so.
Scope is what separates them. A bid assuming sound framing will always beat a bid that assumes otherwise. The cheaper figure is not a better deal. It is a different guess about what sits under the surface. Decks & Balcony builds estimates the other way around, starting from an on-site assessment rather than a square-foot count. The full range of services is laid out at Deck And Balcony. Reading a bid well means finding the assumptions before signing, not after demolition starts.
Start with the license, not the price
Verification takes a few minutes and settles several questions at once. Any California contractor working on this scale should pass all of it without hesitation.
- Confirm the CSLB license number, its status and its classification.
- Check that the license belongs to the company on the letterhead. People leave, and licenses sometimes stay behind.
- Ask for a current certificate of insurance sent directly by the carrier.
- Confirm bonding, and confirm workers’ compensation coverage for the crew that will actually be on site.
- Ask who holds the license and whether that person visits the property.
- For structural work, ask whether a licensed structural engineer is involved and at what point.
A contractor who treats these as routine is used to commercial work. One who treats them as an insult is not. Documents should arrive promptly, not after three reminders.
What “repair the balcony” leaves out
The phrase covers everything and specifies nothing. A useful line item names the assembly, the extent and the finish. Replace joists as required is not a scope. It is a placeholder. Replace joists in the outer third of each balcony above a stated moisture reading, then rebuild the deck to the detail shown – that is a scope. The second version can be checked. The first cannot.
Watch for the words that carry risk quietly. As needed. If necessary. Where accessible. Each one moves a decision out of the contract and onto the job site. Job-site decisions get priced at job-site rates.
Quantities deserve the same attention. A bid should say how many balconies, how many stair landings and how much walkway it covers. Counts drift when nobody writes them down. So does the definition of an element: railings, deck surface and framing are three separate things, and closing one does not close the others.
Allowances and the part nobody can see
Honest estimating on older buildings involves some uncertainty. Nobody knows the condition of every joist before the surface comes off. The difference between contractors is how they handle that.
A weak bid ignores the unknown and issues change orders later. A strong bid names it. It states what was assumed. It sets an allowance for concealed damage. And it defines the unit rate that applies if more turns up. The owner then sees the exposure in advance rather than in week three.
Ask one question of every bidder: what happens if the framing is worse than expected. The answer separates the estimators from the salespeople.
One contract or several
Splitting the work looks cheaper on paper. It rarely finishes cheaper. Every handoff between trades creates a joint that belongs to nobody. Joints are where balconies fail.
- The demolition crew leaves, and the carpenter inherits a substrate they did not inspect.
- The carpenter finishes, and the coating contractor finds the slope wrong.
- The coating contractor seals the deck, and the railing crew drills through it.
- Something leaks, and each firm points at the one before it.
- The manufacturer voids the material warranty because installation deviated from spec.
- The owner ends up managing a dispute rather than a building.
Keeping repair, membrane, surface and railings under one licensed crew removes those seams. It also puts a single warranty on the result. D&B backs its workmanship for two years. The membrane systems carry the manufacturer’s term on top of that, commonly ten to twenty-five years.
Timelines that mean something
Duration estimates should be tied to units, not to the whole property. A typical single-balcony repair, covering joist replacement, surface restoration and waterproofing, runs one to three days. A full balcony reconstruction runs five to ten. Multiply by the count, add mobilization, add weather, and the schedule starts to look realistic.
Phasing belongs in the bid as well. Occupied buildings cannot lose every balcony at once. A credible proposal states how many units each phase affects. It also states how residents get notified and how much warning they receive.
Emergency response is worth asking about separately. Something will need attention outside the schedule at some point. Established clients generally see a twenty-four hour response, and new properties forty-eight.
The line items bids forget
Some costs are real and rarely written down. They surface later as extras, which is how a low bid becomes a mid-priced one.
Staging is the usual example. Lifts need somewhere to sit, and that somewhere is often resident parking. Debris removal is another. Demolished framing and old coating leave the site in a container, and the container needs a permitted spot. Protection matters too: vehicles, landscaping and finished surfaces below the work all need covering.
Working hours belong in the bid as well. Noise rules differ by city, and associations often add their own. A schedule built on ten-hour days may not survive contact with the CC&Rs.
What the paperwork should include
The end of the job matters as much as the middle. Ask what arrives with the final invoice. As-built documentation belongs in the property file. So do photographs of the concealed work, taken before it was closed up. Product data for the installed system belongs there too, along with warranty registration.
That file has a long life. Rental buildings with three or more units are inspected under SB 721 every six years. Association-managed condominiums fall under SB 326 every nine. Staff turns over across those intervals. The next inspector reads records, not memories.
Comparing like with like
The practical fix is simple. Send every bidder the same written scope, or ask each of them to state their assumptions in writing. Then the numbers become comparable, and the cheapest one may still win on merit.
One more efficiency is worth knowing. Combining the inspection and the resulting repairs in one contract typically saves fifteen to twenty-five percent. The reason is dull but real: the assessment work does not get done twice. D&B provides a free on-site consultation with no obligation. A detailed written estimate follows within five business days. That estimate is built to be read line by line. Every bid deserves the same treatment.
