1. Choose your installer
The unit is half the job - the install is the other half. Our own background-checked crews measure, set, seal and insulate every opening, and they know the lines we quote inside and out because they install them every week.
2. Select the right products
Compare styles, materials and glass packages side by side until the fit is right for your rooms, your budget and your goals. The product-line comparison below is the place to start.
3. Prepare your home for install
Before install day we walk you through a short checklist - furniture pulled back, treatments down, a clear path to each opening - so install day is watch-it-happen, not scramble.

Windows & Doors Before & After in Clewiston, FL
Photos don’t hedge. A frame out of square, a seal blown, a sightline that won’t close - these show up in an image whether the salesperson admits them or not. Below are recent jobs we’ve completed in and around Clewiston, documented the way we document every job: measured survey in the customer’s hand, written price before we start, photo record when we’re done. Sonia Raman, Owner.
Recent Transformations

Impact Window Replacement - Single Pane to PGT WinGuard in a 1982 Clewiston Home
The homeowner had been taping plastic sheeting to the interior frames every hurricane season since 2017. The original aluminum single-pane units were factory-installed when the house was built on the west side of Clewiston, and the frames had corroded through at the sill in three locations. We measured every opening with a laser sightline tool - the customer kept that survey - and specified PGT WinGuard vinyl impact-rated units with low-E glazing and a 0.30 U-factor. The written price was $8,400 for twelve openings, and that number didn’t move. We pulled the permits through Hendry County, passed inspection on the first visit, and the photo record shows the tape and sheeting are now in the garage where they belong.
Sliding Glass Door Replacement - Rotted Sill and Inoperable Lock in Harlem Heights Area
The sill was punky halfway across the span, and the lockset had been non-functional for two years - the homeowner was using a dowel rod in the track for security. In the Harlem Heights area just east of Clewiston, that combination of moisture intrusion and failed hardware is common in doors installed before 2005. We specified a CWS impact-rated vinyl sliding patio door with a composite sill cap and multi-point locking hardware. The measured survey showed the rough opening had settled 3/8 inch out of level, which we documented in the photo record and corrected with a tapered sill pan. Written price: $3,850. No change order. The dowel rod is now kindling.
Energy-Efficient Window Installation - New Construction in Pioneer Plantation
This was a new build in Pioneer Plantation, south of Clewiston proper, where the afternoon sun hits the west elevation hard enough to make the framing lumber sweat. The builder had specified minimum-code windows; we talked through what that actually costs in cooling load over ten years. We upgraded the spec to ECO Window Systems vinyl double-hung units with a 0.25 U-factor and 0.20 SHGC - numbers that matter when your AC runs eight months a year. The measured survey went to the homeowner and the builder before we ordered. Written price for nineteen openings: $11,200. The photo record includes a thermal image showing the frame temperature differential after installation. Haven Clause 1, 4, and 5, all in one job.
Impact Garage Door Installation - Non-Rated Door Failing Wind-Borne Debris Code
The existing door was a 1990s-era non-rated steel panel that had taken a direct hit from a landscape timber during Hurricane Irma. The homeowner’s insurance renewal was being held up because the door no longer met the wind-borne debris code for Hendry County. We specified a Mr-Glass impact-rated garage door with a reinforced 14-gauge track and wind-load certification label - the inspector needs to see that sticker, and we photograph it as part of the standard documentation. The measured survey included the headroom and sideroom dimensions, which were tight at 4 inches and 3.5 inches respectively. Written price: $4,600 including track modification. Permits pulled, inspection passed, photo record delivered. The insurance underwriter got what they needed.
Custom Geometric Window - Gable End Triangle in a Lakeport Area Home
The original triangle window in the gable end had failed at the seal, and the previous contractor had removed it and boarded the opening with plywood - for eleven months. In the Lakeport area northwest of Clewiston, that kind of temporary solution tends to become permanent. We measured the rough opening with a digital angle gauge because the pitch was non-standard at 8/12, not the 6/12 the homeowner had been told. The custom PGT impact-rated geometric window was fabricated to the measured sightline, not to a standard template, with low-E glazing matched to the adjacent rectangular units. Written price: $2,400. The photo record shows the plywood in the “before” and the glazing certificate in the “after.” The homeowner said the room finally looked finished. We didn’t argue.
Front Door Replacement - Security and Energy Loss in Downtown Clewiston
The door was a builder-grade hollow-core steel unit installed in a downtown Clewiston home built during the 2004 boom. The weatherstrip had compressed to nothing, the bottom sweep was missing, and the single-pane sidelight transmitted heat like a toaster oven. We specified a Therma-Tru fiberglass entry door with an insulated polyurethane core, multi-point locking hardware, and a matching impact-rated sidelight with low-E glazing. The measured survey caught that the rough opening was 1/2 inch out of plumb - common in that vintage of construction - which we documented and corrected with a composite jamb liner. Written price: $3,200. The photo record includes a blower-door reading showing the air leakage reduction. The homeowner keeps the measured survey in their file with the warranty. We suggest that.
