How to choose a home addition contractor in Utah County

Why addition bids come back so far apart

When three bids on the same addition are thousands of dollars apart, it almost never means one builder is generous and another is greedy. It means they are not bidding the same job. The low number usually left things out: the panel upgrade, the frost footings, the engineer for a second story, the real cost of matching old siding, or a proper cushion for what an older house is hiding. The high number often has all of it in there.

So the cheapest bid is frequently the most expensive one, once the change orders land. The job costs what the job costs. The only question is whether you find out now, on paper, or later, halfway through, when you have no leverage left.

The questions that expose a real addition builder

You do not need to know construction to sort the good from the risky. You need a few pointed questions.

How will you tie the new roof into the old one? This is where additions leak, and it is the clearest tell. A builder who has done it has a plain, confident answer. A vague one is a warning.

What is not in this price? Ask it directly. A real builder will tell you what they excluded and why. Silence here is where the change orders come from.

Is this one contract, or a stack of subs I manage? On an addition the concrete crew, the framers, the roofer, and the plumber all have to hand off cleanly. Find out who owns that. If the answer is that you coordinate the trades, the risk just moved to you.

Who prices the job, who runs it, and who do I call at 4 p.m.? If those are three different people and none of them is the owner, you will feel it when a decision is needed on site.

Can I see additions you have built, not just remodels? Building past the walls you have is a different animal from a kitchen refresh. You want the crew that treats the addition as the main event.

The red flags to walk away from

A few things should end the conversation. A price that is only ever spoken, never written line by line, is not a bid, it is a hope. A number that sits far below everyone else is not a deal, it is a scope that is missing. A contractor who asks you to pull the permit yourself is asking you to carry the liability that should be theirs, and in Utah pulling a permit for work you are not licensed to do is its own problem. And a builder who cannot show you a single addition should not learn on yours.

The floor: license and insurance

A Utah contractor license and real, current insurance are the floor, not the ceiling. They keep you from the worst outcomes, but they do not make someone good at additions. Check them, then keep going. The builder you want clears the floor easily and then answers the harder questions above without flinching.

How to read a bid

Line the bids up against each other and look at what each one includes, not just the total at the bottom. If one is far cheaper, find the line the others have that it does not. Make each builder price the same scope, so you are comparing the same job. We wrote the short version of this as a checklist on our home additions page, and if you are still deciding whether to build up or out, see second story or build out. When you want a bid you can actually read, that is how we work.
