Forget What You Saw on TV. Here's What a Houston Home Remodel Actually Costs.

If you've ever watched a kitchen renovation unfold on television with a $45,000 budget for a complete teardown and rebuild, Troy Ziller, Greymark's Estimator, has something to say about that. He's been estimating construction projects for more than 30 years and doesn't mince words about what renovation shows get wrong. "Remodeling shows on TV are fun to watch," Troy says, "but the pricing they mention is a running joke amongst people in the construction industry who aren't being subsidized by a television network." The gap between what people see on screen and what a project actually costs shapes almost every first conversation Greymark has with a new client.

This post is the honest version of that conversation. What actually drives the cost of a home remodel, what gets overlooked until someone who knows construction walks through the door, and how Greymark's process produces a number you can plan around with real confidence.

What Troy Looks at First

Before a number can mean anything, someone has to actually look at the house. When Troy does, the first things he's assessing are structural requirements at the foundation and framing level, HVAC demands, and finish levels. Those three factors, more than any individual selection or feature, set the floor for what a project is going to cost.

From there, he looks for what homeowners almost never think to budget for, the items that surface consistently enough on major projects that he expects them. "Think engineering, soils reports, multiple surveys for inspectors, code compliance issues, the cost of living somewhere else during construction, movers, and storage of personal items," Troy says. That last part, the logistics of not living in your house while a significant remodel is underway, is one of the most commonly overlooked line items in any project's real cost.

Chelsea Gartner, Greymark's Interior Designer, frames the variability plainly. "We can give a ballpark overall number based on previous and similar projects," Chelsea says, "but it is all dependent on materials, unforeseen conditions, and timeline." That's not a disclaimer. That's the honest description of how remodel costs work before a project is fully designed and understood.

For reference, Greymark typically sees these starting points across project types in Houston, drawn from Remodeling Magazine's Cost vs. Value report and comparable completed projects: primary bathrooms at $70,000 and up, kitchens at $100,000 and up not including appliances, whole house renovations at $250,000 and up, and additions at $75,000 and up for a 50 square foot addition. These are starting points, not ceilings.

The Open Concept Reality Check

One of the most common requests Greymark hears is opening up a floor plan. The image is appealing — walls come down, light floods through, the kitchen connects to the living space the way it always should have. What's less visible in that picture is what's actually in and around those walls.

Troy is direct about what that involves. Not all walls are load-bearing, and removing a non-bearing wall carries a relatively straightforward cost of rerouting any plumbing or electrical running through it. The more significant situation is a load-bearing wall. "If the removed wall is bearing," Troy explains, "then we look at if the beam can be hidden in an attic. Some beams or the studs supporting them will be noticeable in the living space." That structural solution, and whether it disappears into the ceiling or becomes a visible element, has design and cost implications that only become clear once someone who knows what they're looking at has actually walked the space.

This is precisely why Greymark's design and build process starts with a measurement appointment and site evaluation before design begins. The floor plan has to account for what's actually in the building.

Why Estimates Can Look So Different, and What Change Orders Actually Are

When a homeowner gathers multiple bids on the same project and finds numbers that don't resemble each other, the explanation is almost always scope, not price gouging or charity. Kelly Kirk, Owner + President of Greymark Design + Build, puts it directly. "Without fully fleshed out design and structural plans, it's hard to say exactly what is happening and everyone is guessing," Kelly says. "Sometimes it could be quality differences, what is or isn't included, who pays for the tile, whether project management is included, what level of finishes."

Troy adds the contractor's perspective. Bids vary when different firms have different understandings of the required scope. "Often it's a misunderstanding of the required scope of work," he says. "We supply the bidders with our understanding of the required work prior to bidding, but our professional tradesmen may ask for a process that will either help decrease the cost or see a requirement that will add a cost that we didn't anticipate." The number reflects the assumptions built into it, and different firms make different assumptions. The July 7 post on why Greymark doesn't give free quotes goes deeper on this.

A change order is what happens when those assumptions meet reality. In plain terms, Troy describes it as additional work required when a homeowner requests something beyond the original scope, or when unforeseen conditions surface during construction that require repair or modification before work can continue. Water damage, pest damage, a plumbing line in an unexpected location — these are the things no bid can account for because they're invisible until walls open up. "We do our best to look for problematic items during the initial site visits and estimating phase," Troy says, "but unfortunately, we can't see through walls or other finishes without destructive means."

Jorge Arreola, Greymark's Building Designer, describes what the team does to minimize them. "At Greymark, we don't like surprises, and we definitely don't like surprise change orders," Jorge says. "While no remodel can eliminate every unforeseen condition, especially when we're working with an existing home, we do everything we can during design to identify issues early and minimize their impact."

Trade Day: Where the Number Gets Real

One of the most distinctive parts of Greymark's estimating process is Trade Day, and it's worth understanding what actually happens. Once the design is set, Greymark invites all of its bidding trade partners to walk the site together, with the new home design and full scope of work in hand, so every trade can see the existing conditions they'll be working with and flag anything that wasn't caught in earlier walkthroughs.

"This helps our trades provide us an accurate estimate," Troy explains. "Bidding a remodel sight-unseen is not recommended and often leads bidders to adding too much contingency to their estimates. This is a different type of construction than new builds where you can bid purely from blueprints." That distinction matters. A new construction site is a blank canvas. An existing home is a set of conditions and history that only reveals itself once you're standing in it.

Trade Day is the point in the Greymark process where cost accuracy sharpens meaningfully before it's locked in the fixed-price contract.

Why Design-Build Changes the Estimation Equation

When a homeowner hires an architect separately from a contractor, the contractor receives plans and bids from them without having been part of the design conversation. Troy has been on the other end of that process and describes what it looks like. "For a homeowner to provide a contractor with fully detailed plans for a general contractor to bid from is rather expensive," Troy says, "so often all GC's get is a very incomplete set of plans of only a few pages. This forces the estimators to create allowance buckets in their bids that have to be worked out when information is finally provided. Architects are not designers and they won't provide finish selections or details required to get an accurate bid."

Within Greymark's model, Troy is part of the design process from the beginning. That means he understands what the homeowner is trying to accomplish before anyone puts a number to it, and the design accounts for what can realistically be built within the client's investment. The cost conversation and the design conversation happen together, not sequentially.

The result is a progressive accuracy model: a historical approximation at the start of the process, narrowing to within approximately 20 percent after design takes shape, to within approximately 15 percent after selections are made, and a fixed price established in writing before demo begins. By the time a client signs the construction contract, there are no allowance buckets left to negotiate.

The Conversation Has to Start Somewhere

The cost question is almost always the first real question, and it's a fair one to ask early. What it can't be answered with is a number pulled from a television budget or a rough estimate from a contractor who hasn't seen your house. It gets answered through a process, and that process starts with a conversation.
