Meet the Owner
Raul Maravilla
Owner & Founder, Window Specialists of Houston
I started Window Specialists of Houston after spending over a decade working in the construction and home improvement industry across the greater Houston area. I saw firsthand how many homeowners were being sold cheap, underperforming windows by companies that cared more about volume than quality — and I knew there was a better way.
My mission has always been simple: bring Houston homeowners the best window and door products on the market, installed by people who take real pride in their craft. Every job we take on, I treat it like it's my own home. That standard hasn't changed since day one.
“I built this company on the belief that every Houston homeowner deserves premium windows at a fair price — installed right the first time.”
The Brands We Trust
We carry only the top-performing window and door brands on the market — chosen for their energy efficiency, durability, and warranty coverage.
See the Transformation
The difference is undeniable. Our installations don't just improve your home's energy efficiency — they completely transform its curb appeal.

Why Houston Homeowners Choose Us
Expert Installation
Our certified installers have decades of combined experience. Every window and door is installed to manufacturer specs — no shortcuts, no callbacks.
Top-Tier Brands Only
We don't carry budget brands. Every product in our lineup is among the highest-rated in the industry — chosen for performance, durability, and warranty coverage.
Houston-Local Experts
We know Houston's climate, building codes, and neighborhoods. Our recommendations are tailored to what actually performs here — not generic advice.
Backed by Warranty
Our installations are covered by both manufacturer warranties and our own workmanship guarantee. You're protected long after the job is done.
Zero Pressure. Ever.
We believe in educating homeowners, not pressuring them. You'll get honest recommendations, transparent pricing, and all the time you need to decide — no pushy sales tactics, no artificial deadlines.
Proper Flashing on Every Install
Every window and door we install includes a complete flashing system — properly sealed and integrated with your home's water barrier. It's the detail most contractors skip, and the one that prevents costly water damage down the road.
What Our Customers Say
Don't take our word for it. Here's what Houston homeowners have to say about their experience with Window Specialists of Houston.
“Absolutely thrilled with our new Anlin windows. The crew was professional, clean, and finished the whole house in one day. Our energy bill dropped noticeably the very next month. Highly recommend!”
