Window & Door Replacement in Southwest Florida
New windows and doors do three jobs in a Florida home: storm protection, energy efficiency, and curb appeal. DeWitt handles the complete replacement—measurement, removal, installation, and the trim and finish work most window companies leave behind—across Estero, Fort Myers, Cape Coral, Bonita Springs, and Naples.
What we replace
- Impact-rated replacement windows sized to existing block openings
- Sliding glass doors and patio sliders—including heavy multi-panel units
- Entry doors and front-door upgrades that change the whole facade
- French doors and lanai doors
- Garage entry and utility doors
- Interior trim, casing, and stucco/drywall returns finished clean
Why replacement matters here
Between hurricane season and summer cooling bills, windows earn their keep in Southwest Florida. Impact-rated glass adds storm protection without shutters, modern frames and low-E glass cut heat gain your AC otherwise fights all day, and new sliders glide instead of grinding on corroded rollers. Replacement in block construction has to be measured and flashed correctly—water intrusion shows up months later if it is not—so we treat the opening, not just the window, as the job.
The finish is where our renovation background shows: interior casings, stucco returns, caulk lines, and paint are part of the scope, so the new window looks built-in, not swapped-in.
One team, complete scope
As a licensed general contractor (CBC1268482) with electrical and plumbing in-house, we fold window and door replacement into larger remodels or run it standalone—either way, with permits, inspections, and one point of contact.
Frequently asked questions
Do I need impact windows, or are shutters enough?
Both meet code when properly rated. Impact glass protects without any action before a storm and adds everyday benefits—noise reduction, security, UV filtering—while shutters cost less up front. We will walk through the honest trade-offs for your home and budget.
Are permits required for window replacement?
Yes—window and exterior door replacement in Florida requires permits and inspection. We handle both as part of the job.
Can you match my existing openings?
Yes. We measure each opening and order units built to fit, which avoids unnecessary block cutting and keeps the install clean.
Do new windows really lower cooling costs?
Modern low-E, insulated units reduce heat gain compared to older single-pane glass—which matters in a climate where AC runs most of the year. Exact savings depend on your home, but the comfort difference near a west-facing window is immediate.
