Tu prévois rénover ta cuisine, finir ton basement, ou refaire ta salle de bain à Desjardins? Tu vas recevoir des soumissions d’entrepreneurs. Certaines vont être forfaitaires — un prix global pour tout le projet. D’autres vont être détaillées — chaque poste de dépense listé séparément.
The question you're probably asking yourself: which one is best for me?
It's an important decision. The type of bid you accept determines how your budget will be managed, how contingencies will be handled, and whether you'll end up with extras of 5,000 $ or 10,000 $ mid-project.
In Desjardins and the Lévis region, where many homes are 25, 30, 40 or more years old, unforeseen renovation problems are common. Outdated plumbing, non-compliant electricity, hidden structures behind the walls - you often discover things once you've started work.
The real question is not «which bid costs less up front», but «which bid best protects me against overruns and disputes».
Why bidding makes all the difference in home renovation
The type of bid you sign determines who assumes the project risks. In a lump-sum bid, the contractor assumes the risks (in theory). In a detailed bid, you and the contractor share the risks transparently.
But in practice, it's much more complex than that. And unfortunately, a lot of owners get caught out because they don't fully understand the nuances.
In Quebec, we have laws and protective bodies - the Régie du bâtiment du Québec (RBQ) and the Office de la protection du consommateur (OPC). These organizations require detailed, written contracts for all jobs over 2,000 $. But that doesn't stop problems.
Quebec figures: overruns, conflicts and complaints
This is enormous. This means that one project in three costs more than expected.
Average overruns vary between 10 and 30 % of the initial budget, depending on the complexity of the project and the condition of the house. On a 30,000 $ project, this could mean 3,000 $ to 9,000 $ over budget.
Approximately 25 % of complaints filed with the OPC concerning renovation contractors are related to unclear bids, unjustified extras, or work not included in the original contract (reasonable estimate based on OPC public reports).
Most of these disputes could have been avoided with a clear, detailed quote from the outset.
Why Desjardins and Lévis are more at risk
Desjardins, like many areas of Lévis, has a high proportion of houses built before 1980. These homes have charm, they're well located, but they often hide surprises.
When you open a wall to renovate a kitchen, you may discover: lead or galvanized steel plumbing that needs to be replaced, electricity with aluminum wires or non-compliant wiring, non-existent or asbestos-contaminated insulation, structure weakened by humidity or insects.
These discoveries aren't visible until you open the walls. Even the best contractor can't predict them at 100 %.
Notre climat québécois aggrave aussi les choses. Les cycles de gel-dégel causent des fissures, de l’humidité s’infiltre, les matériaux vieillissent plus vite. Une maison de 30 ans au Quebec a souvent subi plus de stress qu’une maison de 50 ans en Californie.
That's why the type of quote you choose makes all the difference. You need a contract that takes these realities into account and protects you when the unexpected happens.
Flat-rate bidding: real advantages... and hidden limits
A lump-sum quote, also known as a fixed price or all-inclusive, is a lump sum for the entire project. The contractor tells you, «I'll redo your entire kitchen for 25,000 $, period.»
Sounds reassuring. You know exactly how much you're going to pay. No surprises, no overruns. In theory.
What a package bid really protects
In ideal situations, a fixed-price quote can work well.
Simple, predictable projects: If you're building a wooden patio on flat ground, Or if you're installing a new floor in a room with no structural problems whatsoever, the lump-sum approach may be appropriate. Everything is visible, so there's little risk of unforeseen circumstances.
Standardized projects: Some specialized contractors offer standardized packages - for example, a complete kitchen with precise cabinetry, quartz countertops, and appliances of specific brands. If you want exactly what's in the package, it can work.
Apparent budget predictability: The main advantage of a flat rate is that you think you know exactly how much you're going to pay. It helps with budgeting, getting a loan and planning.
But beware: this predictability is often illusory.
Common risks at Desjardins
Here are the problems we regularly see with lump-sum bids on our projects at Desjardins and elsewhere in Lévis.
Excluded work not specified: A lump-sum quote will often say «complete kitchen renovation for 25,000 $», but in the fine print or in the exclusions, you'll discover that it doesn't include: plumbing if pipes need to be moved, electricity if the panel needs to be brought up to standard, correction of structural problems, removal of the old floor if it's glued vinyl, painting the walls, and so on.
Result: you sign for 25,000 $, but end up paying 30,000 $ or 32,000 $ because there were lots of things not included.
Extras at 10-20 % of initial budget: In our experience, lump-sum projects on older homes generate an average of 10 to 20 % in extras over the initial price (a reasonable estimate). Sometimes more, if the contractor really underestimated or if there are a lot of unforeseen circumstances.
Reduced quality to keep the price down: Some lump-sum contractors will cut corners to meet their price. They use less expensive materials than expected, they skip invisible steps (insulation, ventilation), or they do things by halves.
Why? Because every dollar they spend goes straight to their bottom line. So they have an incentive to go fast and cheap.
Disputes and conflicts: When something unexpected happens - for example, you open the wall and discover mold - the flat-rate contractor will often say «that's not included, it's an extra». You think it's included in the overall price. Conflict.
These disputes can spoil the atmosphere on the site, delay work, and end up in complaints to the OPC or even in court.

Detailed quotation: the best protection for the owner?
A detailed quote is a document that lists each expense item separately: demolition, plumbing, electricity, cabinets, countertops, flooring, paint, labor, etc.
For each item, you see the quantity, the unit price, and the total. You understand exactly where your money is going.
What RBQ and OPC recommend
The Régie du bâtiment du Québec and the Office de la protection du consommateur strongly recommend detailed quotes for all renovation projects.
Quebec law requires that all renovation contracts over 2,000 $ be in writing, and include: a detailed description of the work to be done, the materials to be used (with brands and models if possible), the total price and payment terms, the work schedule, and any warranties offered.
A lump-sum contract can meet these requirements, but it's much more difficult than a detailed contract. How can you describe all the work in detail if you just give a global price?
Quebec courts and the OPC generally rule in favor of the consumer when the contract is vague or incomplete. But that means months of litigation, stress, and often unfinished work in the meantime.
It's best to have a clear quote right from the start.
How a detailed quote reduces overruns
With a detailed quotation, budget overruns are much rarer and much better controlled.
Complete transparency: You know exactly what you're paying for each item. If the contractor offers you cabinets at 8,000 $ and you find the same ones elsewhere at 6,500 $, you can discuss it.
Written and justified adjustments: If something unforeseen happens - for example, we discover that the plumbing needs to be redone - the contractor writes you an addition to the contract detailing the extra work and the price. You can compare this price with other bids or negotiate. Everything is documented.
Fewer arguments: In our experience, projects with detailed bids generate 10 to 15 % of disputes and complaints compared to lump-sum projects (a reasonable estimate). Why is this? Because everything is clear from the outset. There are fewer gray areas.
Real budget control: With a detailed quote, you can prioritize. If your budget is tight, you may decide to keep your old countertops for another year and invest in plumbing and electricity. With a package deal, it's all or nothing.
Quebec climate and unforeseen events: the decisive advantage
In our Quebec climate, with our older homes having endured 30, 40, 50 years of freeze-thaw, humidity and aging, unforeseen events are almost guaranteed on major renovation projects.
A detailed quotation allows you to manage these unforeseen events transparently and fairly. The contractor shows you exactly what he's discovered, what needs to be done to correct it, and how much it costs.
You can make an informed decision: do I correct it right away, do I postpone part of the work, do I look for cheaper alternatives?
With a fixed price, you don't have that flexibility. It's often a case of «pay the extra or I won't continue».
Detailed quote vs. fixed price - a clear comparison
Here's a table summarizing the important differences between the two types of tender:
| Criteria | Flat-rate | Detailed |
| Transparency | Low - overall price without details | High - every item listed |
| Predictability | Apparent, but often illusory | Real if well documented |
| Managing the unexpected | Frequent disputes over extras | Documented and justified additions |
| Budgetary control | Limited - all or nothing | Excellent - can be prioritized |
| RBQ/OPC compliance | Difficult to comply with | Easy to comply with |
| Litigation risk | High (25 % of complaints) | Low (10-15 % of complaints) |
| Quality of work | Variable - incentive to cut | Best - every position visible |
| Recommended for | Simple, standardized projects | Complex projects, old houses |

Myths and facts about renovation tenders
There are a lot of misconceptions about submissions. Here's what's true and what's not.
Myth: «A detailed quote is always more expensive than a fixed-price quote».»
False. The final cost depends on what's included, not on the type of bid. A lump-sum quote that seems low at first may end up costing more than a detailed quote once all the extras are added in.
Myth: «If I sign a package deal, I can't have any extras».»
Absolutely not true. Almost all package deals include exclusions and extra work clauses. You'll still get extras if problems are discovered.
Myth: «Contractors prefer flat rates because they charge more».»
Not necessarily. Some contractors prefer package deals because they're easier to sell. Others prefer itemized plans because they protect everyone better.
At SRQ, we prefer itemized billing because we want our customers to understand exactly what they're paying for.
Reality check: «A clear quote protects both contractor and customer».»
True. When everything is documented, there are fewer disputes, less stress, and a better working relationship. It's a win-win situation.
FAQ - Renovation quotes in Desjardins
Lump-sum or detailed quotation: which is safer?
For the vast majority of renovation projects, especially on older homes, the detailed quote is much safer. It protects you from unwarranted extras and gives you real control over your budget.
Lump-sum contracts can work for very simple, predictable projects, but they are the exception.
Does a detailed quote cost more?
No. The type of bid doesn't change the actual cost of the work. What does change is transparency and the way contingencies are handled.
A detailed quote can even save you money by allowing you to prioritize and adjust according to your budget.
What does the RBQ say about extras?
The RBQ requires that all extra work be documented in writing and approved by the customer before it is carried out. A contractor can't just do extra work and present you with a surprise bill at the end.
If a contractor refuses to document extras in writing, it's a red flag.
Can you combine flat-rate and detailed pricing?
Yes, some contractors offer hybrid bids: an overall price for the project, but with a detailed breakdown of expense items.
It's better than a pure flat rate, but still less flexible than a truly detailed line-by-line quote.
What to do in the event of a bid dispute?
First, document everything: contract, bid, e-mail exchanges, photos, invoices. Then, try to settle out of court with the contractor.
If that doesn't work, you can file a complaint with the OPC or the RBQ. In serious cases, you can go to small claims court (up to 15,000 $) or consult a lawyer.
Should I always compare 3 quotes?
This is highly recommended, especially for large projects. Three bids allow you to compare prices, approaches and quality of communication between contractors.
But don't just compare price. Also look at the clarity of the quote, the warranties offered, the RBQ license, and the references.
