General Contractor in Houston, TX | Reddit & LinkedIn

Houston general contractor cost depends on the project. A kitchen remodel managed by a GC runs $32,000 to $68,000 in 2026, a whole-home remodel runs $48,000 to $145,000, and a room addition runs $180 to $320 per square foot. These ranges come from 2025 to 2026 quote data inside the ContractShield Work Order Marketplace.

A general contractor markup in Houston typically lands at 15 to 22% of total project cost. That markup covers scheduling, trade coordination, permit handling with the City of Houston, supervision, and warranty. Pros bidding inside ContractShield must show the markup line on every quote, so you can see what you pay for management versus materials and labor.

A Houston general contractor runs the project end to end. They pull permits under their license, hire and schedule subcontractors, order materials, manage inspections with Harris County, and keep the build on timeline. On a remodel, the GC also handles demolition sequencing and protects the parts of your home that stay in place.

The value of a GC shows up most on multi-trade jobs. A bathroom remodel touches plumbing, electrical, tile, and drywall. Coordinating those trades yourself means four schedules and four points of failure. A GC absorbs that coordination so you have one accountable party.

• Confirm the GC holds the correct City of Houston registration for your project size.
• Ask whether your project needs a structural engineer stamp before bidding.
• Request two recent Harris County references for similar scope.

Median quote send time for Houston general contractor contractors on ContractShield is about 25 minutes from site arrival to a signable estimate — walk the job, drop photos, set labor and materials, apply your markup, and tap send. An AI draft of labor, materials, and markup is ready in under a minute. Speed-to-quote is the single biggest driver of close rate, and a quote that lands the same day beats one a client waits two days for.

Once the client accepts, the project workspace takes over. Tasks, photos, time tracking, progress payments, and change orders all live in one place, so you run the whole job from the truck instead of chasing email threads and texts.

Compare bids on scope, not just the bottom line. A low Houston GC bid often hides thin allowances for tile, fixtures, and cabinetry that balloon into change orders later. ContractShield normalizes bids into the same line-item format, so you can see allowance amounts, labor, and markup side by side.

Also compare timelines and payment schedules. A GC who front-loads a large deposit carries more risk for you than one who ties payments to completed milestones. Texas does not cap residential deposits by statute, so the payment schedule is your main protection.

Per-lead platforms sell the same general contracting lead to four or five shops, charge $20 to $50 a pop, and most of those leads never close. ContractShield flips that math. You build a line-item general contracting bid — labor, materials, and markup — in about 25 minutes, with an AI draft ready in under a minute, then send a clean quote your client can accept on their phone.

From there the whole job runs in one workspace: tasks, photos, time tracking, change orders, and milestone payments. You only pay when you get paid — a flat 2% per job, 1% client and 1% contractor, capped at $250 per job. No seat fees, no per-lead charges, ever.
