When planning a home renovation, one of the most important decisions you’ll make is how your contract is structured. Will you go with a fixed price or a variable price contract? This choice can dramatically affect your renovation experience, both financially and emotionally. Let’s break it down and explore why a fixed price contract is the best choice for a stress-free, on-time, and on-budget renovation.
Why Fixed Price Contracts Are the Best Choice
A fixed price contract ensures your renovation runs smoothly, is completed on time, and most importantly, stays on budget. With a fixed price agreement, you know upfront exactly what your renovation will cost. There are no surprises, no hidden fees, and no stressful mid-project cost blowouts. Everything is outlined before work begins, providing you with peace of mind throughout the entire process.
In contrast, variable cost contracts immediately put you at a disadvantage. Instead of focusing on the progress and excitement of your project, the conversation between you and the builder often revolves around one thing: money. With a variable cost agreement, it’s almost guaranteed that costs will exceed the initial estimate, creating tension and disappointment along the way.
The Risk of Variable Cost Contracts: Money Worries Throughout the Build
With a variable cost contract, there’s a constant worry that costs will go up—and they usually do. This uncertainty turns the renovation into an uncomfortable experience. Conversations with your builder will often centre around unplanned expenses, leaving you feeling uncertain and frustrated. This stress can dampen the entire renovation experience for both you and the builder. The excitement of seeing your vision come to life is overshadowed by the worry of how much it’s going to cost in the end.
Professional Builders Use Systems to Guarantee Fixed Price Contracts
Not all builders are equipped to offer fixed price contracts. Professional builders, like those at Swanson Constructions, have the right systems in place. We use advanced estimating software, employ a highly skilled team, and have years of experience to confidently offer and honour fixed price contracts. This level of expertise means we can anticipate costs accurately, giving you a reliable budget from the outset.
On the other hand, cost-plus or variable price builders often “wing it.” Without the proper systems, they are unable to fix the price because they can’t accurately estimate the project’s costs. This lack of planning often leads to surprise expenses, and unfortunately, you’re the one who ends up paying for it.
Timelines: Fixed Price Contracts Keep the Project Moving
A big myth in construction is that fixed price contracts slow down the project. In reality, it’s the variable price contracts that causes delays. Why? Because every change in cost requires approval from you, the client. This leads to back-and-forth conversations, pay disputes, and prolonged decision-making—adding weeks, or even months, to the project timeline.
With a fixed price contract, everything is agreed upon before construction begins. There’s no need for ongoing cost approvals, which means the project moves forward without unnecessary delays.
Addressing Variable Cost Items Like Earthworks and Rubbish Removal
You might be wondering: Why are certain costs, like earthworks or rubbish removal, not fixed?”
At Swanson Constructions, we specialise in renovations and extensions, and while we can confidently estimate labour and material costs, some things are harder to predict. For example, earthworks depend on soil conditions, and rubbish removal can vary depending on the volume of debris generated during the project. These factors can’t always be accurately measured upfront.
That’s why we take great care to utilise soil reports and experienced earthwork teams to provide the best possible estimate for these items. Typically, a 5% margin of error is expected, which is fair for both you and us. This approach ensures you won’t be hit with extreme surprises while keeping the budget flexible enough to cover the unpredictable.
Variable Costs from Client Selections: Plan Ahead to Stay on Budget
Another source of variable costs comes from changes in client selections. It’s completely normal not to have everything finalised before the build begins. However, we strongly recommend locking in your choices as early as possible. This helps ensure that your selections are available at the best prices, and it gives us time to stay within the allowance budgets set in your fixed price contract.
Planning ahead reduces last-minute decisions, price hikes, and delays. The more organised you are, the smoother your renovation will be.
Conclusion
If you’re planning a renovation, a fixed price contract is the only way to ensure the project runs smoothly, stays on time, and remains on budget. Variable cost contracts might sound flexible, but they come with hidden risks—mainly cost blowouts and unnecessary stress.
At Swanson Constructions, we have the experience, systems, and team to offer you a clear, fixed price contract with no surprises. Let’s work together to make your renovation experience enjoyable, transparent, and worry-free.
