Bay windows, bow windows, or specialty architectural shapes
Historic homes with non-standard opening sizes
Unique design requirements like arched or circular windows
Matching existing custom windows in older homes
Commercial-grade windows for residential applications
Multi-panel configurations for panoramic views

Frequently Asked Questions
Custom windows typically take 4-6 weeks from measurement to installation — that's manufacturing time plus scheduling. We measure precisely on day one, then your Andersen or Simonton windows are built to your exact specifications. Once they arrive, installation usually takes 1-2 days depending on how many windows you're replacing. We'll give you a clear timeline upfront, no surprises.
Custom windows run about 15-30% more than standard sizes. The exact difference depends on your specific needs — unusual shapes, specialty glass, or historic trim work all factor in. We price everything transparently: materials, labor, and any structural modifications needed. No hidden fees, no surprise add-ons. We'll show you options in both standard and custom so you can make the choice that fits your home and budget.
Yes, we work with Houston's historic homes regularly — from Heights bungalows to River Oaks estates. Our installers know how to match original profiles, maintain architectural integrity, and meet preservation guidelines when needed. Both Andersen and Simonton offer extensive custom options for grid patterns, trim styles, and hardware finishes. We'll take detailed measurements and photos to ensure your new windows honor your home's character.
Both manufacturers stand behind their custom windows with comprehensive warranties. Andersen offers their Owner-2-Owner warranty that transfers if you sell. Simonton provides lifetime coverage on vinyl components. The specifics vary by product line, but custom windows carry the same protection as standard sizes. We'll explain the warranty details for your specific windows — in plain English, not legal jargon.
We handle all measurements ourselves — it's too important to leave to chance. Our installers measure the rough opening, existing frame dimensions, sill angle, and wall thickness. For historic homes, we also document trim profiles and any unique architectural details. This precision work happens during your free consultation. You don't need to climb any ladders or figure out a tape measure. That's what we're here for.
