Doors & Windows Estimating in Houston
Precise schedules for commercial doors, hardware, storefront, and curtain wall systems. Tailored to Harris County requirements.
The "Divisions 8" package (Doors and Windows) is one of the most complex scopes in commercial construction - with intricate hardware sets, ADA compliance requirements, fire-rating implications, and glazing performance specifications all packed into a single scope - and in Texas it carries one regional variable most national estimating templates skip entirely: the Texas Department of Insurance Windstorm Insurance Program's wind-load requirements for glazing systems in the 14 coastal counties and catastrophe area.
For commercial projects in windstorm territory, glazing has to meet specific wind resistance ratings, and the framing systems that carry it have to be designed to match. An estimate that prices standard commercial storefront in a coastal Texas county and discovers the TDI requirement later is looking at a scope and cost change on every opening.
Scopes We Estimate
Doors, Frames, and Hardware (DFH)
Hollow metal doors and frames, solid core wood doors, and specialty doors (coiling overhead, acoustic, lead-lined). We dissect complex hardware sets (closers, panics, electrified hardware) to ensure every component is priced - not an allowance for "Hardware Set #1" but the individual hinges, lockset, closer, kickplate, and stops that set actually requires, so purchasing matches the installation scope.
Commercial Glazing and Storefront
Aluminum storefront systems, curtain walls, operable windows, and interior glass partitions. We calculate the square footage of glass (by type: Low-E, tempered, laminated) and the linear footage of aluminum framing, with glazing type and performance requirements confirmed against the spec before pricing.
Texas Windstorm Requirements
For projects in the Texas Department of Insurance (TDI) catastrophe area, we identify impact-resistant glazing requirements and the heavy-duty framing systems required to meet TDI wind load specifications - and price them explicitly rather than assuming standard commercial storefront applies statewide.
Software and Standards
Doors and glazing takeoffs are built in Bluebeam and Planswift, with hardware sets priced component by component and glazing systems sized against manufacturer specification data. Texas Department of Insurance windstorm requirements are confirmed for the project's county before pricing coastal glazing scope.
Building in Houston: What Changes the Estimate
Houston Construction Market Overview
As the largest city in Texas and the energy capital of the world, Houston's construction market is massive and diverse. From sprawling suburban residential developments in Cypress and Katy to high-rise commercial towers downtown and massive industrial complexes along the Houston Ship Channel, estimating in Houston requires deep local knowledge.
Our Houston estimates account for critical local factors: expansive "gumbo" clay soils that dictate heavy foundation engineering, Gulf Coast windstorm and hurricane resistance requirements (TWIA), and the unique logistical challenges of building in a sprawling, flood-prone metropolitan area.
Houston & Harris County Permitting
The City of Houston is famous for having no formal zoning laws, but that doesn't mean building is a free-for-all. Deed restrictions act as de facto zoning, and the City of Houston Public Works department enforces strict commercial and residential building codes. Our estimates can include allowances for Harris County floodplain management permits, City of Houston impact fees, and the often-lengthy Houston plan review process.
Our Process for Houston Projects
Meticulous review of the architectural door schedule, window schedule, and hardware groups.
Verifying counts on the floor plans and measuring dimensions for all glazing systems.
Breaking down curtain wall and storefront into glass area and linear framing.
Applying material costs and installation labor based on the complexity of the systems.
Frequently Asked Questions
Do you break down hardware sets?
Yes. We don't just estimate a "Hardware Set #1" allowance. We list out the hinges, lockset, closer, kickplate, and stops required for that set to ensure accurate purchasing.
Can you estimate automated entrances?
Yes. We estimate automatic sliding doors, ADA operators, and the associated sensors and controls.
Do you estimate residential windows?
Yes, for custom homes or multi-family projects, we provide complete window schedules detailing size, operation (single hung, casement), and glazing specs.
Do your Houston estimates account for hurricane requirements?
Yes. For projects in Houston and Harris County, we estimate the required wind-rated assemblies, impact-resistant glazing, and enhanced structural tie-downs required by Gulf Coast building codes and the Texas Windstorm Insurance Association (TWIA).
How do you handle Houston's soil conditions in estimates?
Houston's expansive clay soil requires specialized foundations, typically heavily engineered post-tension slabs or drilled builder's piers. We never estimate Houston foundations using standard national averages; we always use the specific structural design or historical local data for soil remediation and foundation work.
