4 Helpful Reasons Why Your Contractor Estimates Are All Over the Place

One of the most common questions that homeowners looking to remodel ask is: I have estimates from three different contractors for the same project. Why are their prices so different? Understandably, this is a mystery to most people. We don’t expect the same blender or microwave to cost vastly different amounts at three different stores. Why should the cost of the same remodeling project vary so much? Sometimes, the difference in contractor estimates can cause significant stress for a homeowner. They feel like the low bid must be “missing something” and the high bid must be gouging them. Often, people will just pick the middle one because they don’t know what else to do.

At GreatBuildz, a free service that connects homeowners in Los Angeles, Orange County, Ventura & San Diego with reliable general contractors, we hear from lots of homeowners confused about this very issue.

Here are the main four reasons why contractor estimates vary so greatly.

The Contractor’s Desire to Win the Job

If a contractor is having a slow period, they want more jobs to keep their crews busy. They are likely to be more ‘aggressive’ on pricing potential projects in order to win the bid. Alternatively, if a contractor is inundated with jobs they will often bid on the high side. The contractor is essentially saying, “I’m too busy for this job right now so I’m bidding high because I don’t need it. If the homeowner wants to pay this high of a price, I’ll find a way to do the job because it will be very profitable.”

Contractor’s Overhead/Costs Impact On Contractor Estimates

There are many types of contractors in the world of construction. They range from a one-man operation to large corporate organizations with hundreds of staff. Some work from a high-rent corporate office and some work out of their home. Some contractors spend hundreds of thousands each year on advertising and some rely on word of mouth referrals. As you can imagine, their ‘overhead’ costs will greatly affect how much profit they expect to make on each job and that will be reflected in your project bid/estimate.

Contractor’s Assessment of the Project

Although you know what you want to be remodeled and try to convey that clearly to each prospective contractor, they each have their own ‘understanding’ of what the project will require. Since materials, like kitchen cabinets, can vary widely in price, a contractor’s assumption of the materials to be used can greatly affect their bid. Some contractors like to be very thorough and include the costs of potential unknown issues (for example repairing ceilings that aren’t perfectly level) and therefore their bid might be high.

Others will include only the bare minimum required for the job, and their bid will likely be on the low side. However, they are likely to request ‘change orders’ or ‘extras charges’ during the job for any unforeseen issues, driving the total costs up. While it’s extremely hard to know exactly what is ‘included’ in the contractor estimates, a homeowner can get more accurate bids by doing a few things.

– Providing a clear written scope which is as detailed as you can make it.
– Providing approximate cost expectations (allowances) for each major material included in the project.
– Asking the contractor specific questions about what is/isn’t included in the job and what types of items will require a change order.

Another difference is that some contractors have their own construction workers (crew) on staff and other contractors will retain multiple sub-contractors to complete each project. Since each sub-contractor is another company, they will each require their own profit margin for each job, adding to the total cost for the homeowner. This is an important question to ask when considering a contractor: Will you be using your own crew or sub-contractors to perform the work?”

Although hiring a contractor with their own crew is often cheaper, it is important to make sure that their staff is experienced doing each type of work required on the project, whether it be plumbing, electrical, tiling etc. The worst scenario is the contractor doesn’t have an experienced tile guy and uses their carpenter to install tile. Trust me, it will turn out terrible.

The Other “Stuff”

When a contractor comes to your house, you are judging them on their appearance, personality and communication skills. It’s human nature. Well guess what… they are judging you too. They are judging whether you will be a good client to work for. Are you organized? Do you have a clear written description of the renovation or are you constantly changing your mind on what you want? Do you have realistic expectations about time and money? And this one may surprise you, but some are judging your house and neighborhood.

If you live in a fancy house or a fancy neighborhood that’s a really good sign you can afford an expensive remodel. The point here is you need to be organized and prepared before you meet contractors so that you can tell them the exact renovation you require and your approximate budget. The more you know about your remodel and budget when you meet a contractor, the more likely you’ll get the most accurate estimate back. It is also important to know how to spot a dishonest contractor so that you are not taken advantage of when the estimate arrives.
