Central Florida's heat, humidity, and storm season are harder on windows than almost anywhere else. Here's what homeowners in our area tell us they noticed first.
Fogged or Cloudy Glass
That permanent haze between the panes means the insulating seal has failed, and no amount of cleaning fixes it. The window has to go.
Rooms That Stay Hot
Single-pane windows offer almost no thermal resistance. If your AC runs constantly and certain rooms still feel hot, old windows are often the reason.
Drafts, Leaks, or Moisture
Feeling air movement around a closed window, or finding water on the sill after rain, means the seal is gone. In Florida, that also invites mold.
Worried About Storm Season
Older windows weren't built to today's wind and water standards. If your windows rattle when a storm rolls through, it may be time to upgrade.
Road Noise Inside the House
Modern dual-pane windows significantly reduce outside noise. If you live near a busy road, you'll notice the difference the day they go in.
Sticky, Drafty, or Hard-to-Open Doors
Sliding glass doors that are difficult to operate, or that no longer seal properly, are both energy wasters and security concerns worth addressing.
The Colonial Difference
When you call Colonial, you talk to the owner. When we come to your home, the owner is there. That's how we've done business for 30 years, and we're not changing.
Deal Directly With the Owner
No salespeople. No call centers. No commissioned reps. You get honest, straightforward pricing from the person who stands behind every job.
Consistent, Trusted Installation Crew
Tom works with the same experienced crew he's relied on for years, familiar faces who know the work, personally overseen on every job. That's why quality stays consistent.
Lower Overhead, Better Price
No showroom. No giant office. No layers of management. We pass those savings on to you with competitive pricing you won't find from big-box companies.
I'm proud that Colonial Industries is a family owned business. We've worked hard to earn the business of each and every customer, one window, one sliding door at a time. It's an honor to be trusted by so many Florida homeowners, and it's why we've had such a great track record for 30 years.
A Family Business Built on Trust
Colonial Window & Door was built on a simple idea: treat every homeowner the way you'd want your own family treated. Tom Davy has spent 30 years proving that principle works, earning an A+ BBB rating and a reputation for 5-star service from homeowners across Central Florida.
When you call Colonial, you're talking to the owner, not a salesperson. Tom handles every estimate personally, works with the same trusted installation crew he's relied on for years, and oversees every job from start to finish.
