New windows and doors improve comfort, cut energy bills and add long-term value to your home. Sightline Windows & Doors Clewiston pairs proven product lines with our own installing crews for lasting performance - and a price we put in writing.
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.

Meet the Clewiston Team Behind Sightline Windows & Doors Clewiston
Every window and door we install in Clewiston passes through the hands of the same crew that’s been working this territory since we opened here. We’re not a dispatch service pulling from a pool. When you call (863) 509-1135, you’re reaching people who know which way the afternoon storms track across Hendry County, who’ve measured openings in the historic homes near Sugarland Highway and the newer construction off West Ventura, and who treat the Haven Standard as a working document, not a poster on the wall.
Our People

Sonia Raman, Owner
I started Sightline in 2012 because I’d watched too many homeowners in South Florida get a verbal price that ballooned once the crew was halfway through the job. That still makes me tired. My background is in commercial glazing specification - I spent years reading shop drawings for impact-rated assemblies before I ever ordered my first truck. These days I split my time between measuring jobs in Clewiston, reviewing every written quote before it leaves our office, and checking the photo records from completed installations against the scope documents. I keep a framing square on my desk that I inherited from a glazier in Miami who taught me that the measurement and the quote should never be two different conversations. When I’m not on a job site, I’m usually fishing the canals near Lake Okeechobee, badly.
Marcus T., Lead Technician
Marcus has been installing windows and doors in Hendry and Glades counties for fourteen years, and he still catches things other people miss - a subtle rake in a header, a sill pan that won’t drain the way the manufacturer drew it. He’s NAMI-certified for impact product installation and handles our PGT and CGI lines on jobs where the wind-load calculations matter, which in Clewiston means most of them. Marcus is the one who trains our apprentices on how to read a sightline measurement without guessing, and he’s got a running bet with the supply house that he can identify any window manufacturer’s corner profile by touch alone. He hasn’t lost yet. On weekends he restores vintage air-cooled Volkswagens, slowly.
Dolores V., Senior Installer
Dolores came to us from a high-end custom home builder in Naples, where she specialized in geometric and architectural window installations - the kind of openings that make most crews nervous. She runs our custom and specialty window work, including the ES Windows and ECO Window Systems lines with their more complex glazing sequences. Her particular skill is retrofitting older Clewiston homes where the original openings weren’t built to modern standards, figuring out how to get a contemporary impact-rated unit into a frame that predates the current Florida Building Code by decades. Dolores speaks Spanish with our Spanish-speaking homeowners and prefers to explain the installation sequence in person rather than hand them a brochure. She has three rescue dogs and a vegetable garden that the afternoon sun has mostly defeated.
James K., Service Coordinator
James answers the phones and schedules the work, which sounds simple until you try doing it while a homeowner in Clewiston is describing a leaking sliding door and a contractor is waiting on a jamb extension measurement. He’s been with us since 2019 and knows every product line we carry well enough to spot when a competitor’s quote has specified the wrong performance grade for a given exposure. James handles the measured survey appointments, makes sure the written price document matches what Sonia approved, and coordinates with our manufacturers on lead times for custom orders from ViewLux or Therma-Tru. He grew up in LaBelle and still drives back for his mother’s cooking on Sundays. He will not disclose what she makes.
Elena R., Apprentice Installer
Elena joined us in 2023 after completing the construction technology program at Florida SouthWestern State College. She’s working through her NAMI installer certification under Marcus’s supervision and has already taken point on several standard replacement window jobs in the newer Clewiston subdivisions. Her eye for level and plumb is unusually good for someone early in their career, and she’s developed a particular competence with our CWS and Mr-Glass product lines. Elena documents every job with the photo record we require under Haven Clause 5, and she’s been known to take extra shots of details she wants to ask Marcus about later. She lives in Moore Haven and commutes across the county line every morning, usually with a large coffee and a podcast about true crime that the rest of us have asked her to stop describing at lunch.
Before
AfterOne Standard, Every Job
Sightline Windows & Doors Clewiston operates independently under the Haven Standard that governs every installation across our network. That standard isn’t abstract for us. Haven Clause 1 means the written price you receive before any work starts is the price you pay - Sonia reviews every quote personally, and the measurement document becomes the scope document. Haven Clause 3 means the technician who arrives at your door in Clewiston is background-checked, uniformed, and identifiable by license number; no substitutions, no surprises. Haven Clause 5 means Elena photographs every stage, and you keep that record along with your warranty documentation.
We’ve installed more than 18,000 windows and doors since 2012, and the ones we’ve done in Clewiston - from the impact-rated retrofits near the historic district to the energy-efficient packages in newer construction off Santa Barbara Boulevard - share one trait with every other job. The homeowner knew the price before anyone picked up a tool, and they had evidence of what was done after the last screw went in. That’s not a courtesy we extend when things go well. It’s the operating system. If you want to talk through what your particular opening needs, call (863) 509-1135. A live person answers, even at odd hours, and we’ll schedule a measured survey you can keep and compare.
