Bright sunroom additions that bring in Galveston light while controlling heat, humidity, drainage, and coastal exposure. Licensed Galveston contractors. Coastal-grade planning. Free estimates.
A sunroom should give you light without turning into a hot glass box. In Galveston, that balance depends on window selection, shade, insulation, air movement, waterproofing, and how the addition connects to the existing home.
We plan sunrooms as real living spaces, not afterthoughts. That means structure, foundation, roof tie-in, HVAC, electrical, flooring, and permitting are considered together.
Whether you want a reading room, breakfast space, rental-friendly sitting area, or flexible family room, we shape the sunroom around comfort first.
This page is part of our home additions service family. If your project touches more than one room or area, we can connect it with the right neighborhood page, budget range, and construction sequence.

Sunroom additions may trigger elevation, floodplain, drainage, or site-plan review depending on the property.
For older homes, we keep proportions, roof forms, and exterior details respectful of the original structure.
We plan orientation, shade, glass, and airflow so the room stays pleasant in summer conditions.
We keep the process simple, documented, and easy to follow.
We inspect the space, listen to your goals, and identify early code, moisture, access, or structural concerns.
You get a written scope with practical options, allowances, and material direction before making decisions.
We help choose finishes, fixtures, and details that fit your budget and coastal maintenance needs.
Our team protects the home, coordinates trades, communicates progress, and handles inspection timing when needed.
