Window & Door Replacement in Harris & Surrounding Counties

Energy-efficient windows and durable entry, patio, and interior doors installed with proper flashing and sealing for Houston heat and storms.


Window & Door Replacement

Comfort, Efficiency, and Security in Every Opening

Window and door replacement improves comfort, energy efficiency, security, and curb appeal all at once. In the Houston area, old or poorly sealed windows let in intense summer heat, humidity, and drafts, while worn exterior doors can stick, leak during storms, and compromise security. Even high-quality products underperform when flashing, insulation, and sealing are not installed correctly. Oakmont Construction Group replaces windows and doors for homeowners in Harris & Surrounding Counties, including energy-efficient replacement windows, entry doors, patio and sliding doors, and interior doors. We focus on proper flashing integration with siding and brick, careful insulation and air sealing around frames, and clean interior and exterior trim. With more than 23 years of experience, our locally owned team helps you compare styles, materials, and glass options suited to Texas heat, communicates dependably, cleans up thoroughly, and backs our workmanship with a limited one-year warranty.

Openings Sealed Against Heat and Rain

Window and Door Installations That Perform as Promised

Even premium windows and doors fail when installed poorly. These practices help every opening we replace stay sealed, efficient, and attractive.

Flashing Integrated With Your Exterior

Windows and doors must work with the brick, siding, or stucco around them. We integrate flashing properly with your existing exterior, directing Gulf Coast rain away from openings and protecting framing and interior walls. It helps every project finish strong.

Gaps Insulated and Sealed

Drafts and heat gain often come through gaps around frames rather than the glass itself. We insulate and seal these gaps carefully, improving comfort and helping your air conditioning work less during long Houston summers.

Glass Options for Texas Sun

Low-E coatings and insulated glass reduce heat gain and fading from intense sunlight. We explain glass and frame options clearly, helping you choose windows that balance comfort, efficiency, appearance, and budget for your home. That care extends to every corner.

Doors Hung Plumb and Square

Entry, patio, and interior doors are installed level, plumb, and properly shimmed, so they swing smoothly, latch securely, and seal tightly against weather. Precise installation prevents sticking, gaps, and premature wear on hardware. Our process was built around this.

Security Considered at Every Entry

Exterior doors and patio doors affect home security. We recommend sturdy door options and install quality locksets and reinforced strike plates where appropriate, helping your family feel safer every time you lock up. That is a commitment we keep.

Trim Finished Inside and Out

New windows and doors should look like they belong. We finish interior casings and exterior trim neatly, caulk joints cleanly, and leave every opening polished, so the upgrade improves both performance and appearance immediately. It reflects decades of hands-on experience.

Common questions

Frequently Asked Questions

New windows and doors raise questions about efficiency and installation. Here are answers for homeowners in Harris & Surrounding Counties

  • How do I know if my windows need replacement?

    Drafts, condensation between panes, difficulty opening or closing, rotting frames, fading furniture, and rising energy bills are common signs. An evaluation helps determine whether repair or full replacement makes the most sense. Your satisfaction comes first.

  • What is low-E glass?

    Low-E glass has a thin coating that reflects heat, helping keep homes cooler in Houston summers while reducing ultraviolet rays that fade floors, furniture, and artwork. It is a popular upgrade for Texas homes. We confirm before starting.

  • Can new windows lower my energy bills?

    Energy-efficient windows with quality installation can reduce heat gain and drafts, which may help lower cooling costs. Actual savings depend on your home, existing windows, and overall insulation and HVAC efficiency. We discuss this upfront.

  • Are impact-resistant windows worth it?

    Impact-resistant windows and doors provide added protection during severe storms and can improve security and noise reduction. They cost more than standard units, and we help you weigh benefits against your budget. We tailor every recommendation.

  • Will installation damage my siding or brick?

    Some surrounding material may need adjustment during installation. Because we also handle siding and exterior work, we repair surrounding surfaces properly, integrating flashing and trim so openings stay weather-tight and attractive. We keep recommendations realistic.
