How to Choose a General Contractor

Choosing the wrong general contractor is one of the most expensive mistakes a homeowner can make. The difference between a smooth remodel and a months-long dispute often comes down to what you check before anyone picks up a tool. Here is how to sort the contractors worth trusting from the ones you will regret.

What’s Happening

A finished backyard cottage with a small covered porch

When you search “how to choose a general contractor,” you are almost always standing at the beginning of a real project – a bathroom gut, a whole-home remodel, or a structural job that needs a licensed crew and a real plan. The question usually surfaces right after you have gotten one wildly low bid, one impossibly high one, and you are now wondering what a fair number actually looks like and who you can trust inside your home.

That instinct to pause and research before signing anything is correct. The general contracting industry has a well-documented problem with verbal promises, bids that grow after work starts, and crews where nobody can tell you who, exactly, is showing up at your door. The steps below will help you cut through the noise and identify a contractor who prices honestly, stands behind the work, and sends people you actually feel comfortable letting in.

Why It Happens

Bids That Seem Too Low

A bid that undercuts everyone else by 30 or 40 percent is almost never good news. Low bids typically signal one of three things: the contractor plans to use cheaper materials than specified, they intend to add change orders once demolition has started and walking away feels too costly, or they simply are not accounting for the full scope of work. If a number feels too good to be true, ask the contractor to itemize every line – labor, materials, permits, and disposal. A contractor who cannot or will not do that is showing you something important.

No Written Contract Before Work Starts

Verbal agreements in construction almost always benefit the contractor, not the homeowner. If a contractor asks you to sign a work authorization or pay a deposit before producing a written price with line items, stop there. A legitimate contractor gives you a written price before any work begins – not after the walls are open. If the paperwork comes late, the price tends to climb.

Vague or Missing Guarantee Terms

Most contractors say some version of “we guarantee our work.” Ask them to put it in writing and describe exactly what is covered, what is excluded, and for how long. A guarantee that cannot be written down in plain sentences is not a guarantee – it is a talking point. Gaps in workmanship coverage typically surface at the twelve-month mark, which is exactly when most verbal promises expire by convenient coincidence.

Uncertainty About Who Is Actually Coming to Your Home

A general contractor coordinates multiple trades – framers, plumbers, electricians, tile setters. That means strangers coming through your door over days or weeks. If you ask “who exactly will be in my home and when?” and the answer is vague, that is a real gap. A contractor who cannot tell you the names and backgrounds of the people they send is one you cannot adequately evaluate on safety alone, which matters especially if you are home during the work or if children or older family members are present.

What to Do Right Now

  • Write down your scope before you call anyone. A clear description of what you want – which rooms, what changes, any structural work – protects you in every conversation. Vague scope is how costs grow after signatures.
  • Ask every candidate for a written, itemized price before you agree to anything. Not a ballpark. Not a range. A written document with line items for labor, materials, permits, and any subcontractor costs. If a contractor resists this step, move on.
  • Ask specifically about the guarantee – in writing. What is covered, what is not, and for how many months or years after completion. Make sure it addresses workmanship, not just materials.
  • Find out who will be in your home, by name. Ask whether technicians and subcontractors are background-checked and whether you will be notified before each visit. This is not an unusual request – a contractor who treats it like one is telling you something.
  • Do not let urgency override this process. A contractor who tells you the price is only good for 48 hours, or that another customer is about to take your slot, is using pressure tactics to stop you from reading carefully. A project worth tens of thousands of dollars deserves a few days of due diligence.

How We Fix It

When you contact your local Mason Remodeling team, the first step is a conversation about scope – not a sales pitch. We want to understand exactly what you are trying to accomplish before we put anything in writing.

From there, we produce a written price before any work starts. That is not a promotion or a special offer; it is how we operate on every project, every time, under the Threshold Standard. The document covers labor, materials, and the project timeline so you know what you are agreeing to.

Every technician on your project is background-checked and identity-verified. Before anyone arrives at your door, you receive their name and photo. They show a photo ID badge on arrival. They arrive in a clean, marked uniform. This applies to crew members on General Contracting projects and on every Home Remodeling engagement we take on.

Every completed project is backed by our 365-Day Done Right Promise: if the work is not right within a year of completion, we come back and make it right at no cost to you. Coverage terms are stated plainly in writing – what is covered, what is not, and for how long. Call (803) 680-2547 to schedule your free written estimate.
