Why TruePane Windows & Doors Is Longwood’s Preferred Window Replacement Company

TruePane has been installing and replacing windows in Central Florida since 2008 under the founding rule Dale Kessler still keeps on the whiteboard: if the pane is not true, the job is not done. That rule carries extra weight in Longwood, where the housing stock runs from 1870s wood-frame historic homes to 1990s concrete-block split-levels and each one demands a different set of skills, materials, and paperwork. We’re not a franchise operation with a rotating crew. Our technicians are background-checked, uniformed, and trained in-house, and a live person answers our phone 24 hours a day, 7 days a week. When a Longwood homeowner calls at 6 a.m. or 10 p.m., they get a person, not a voicemail tree. That matters to the folks who live here, and frankly, it should matter to you as well.

Every job we complete in Longwood is covered by the Done Right Promise, which means if the install is not right, we fix it without paperwork fights or fine print. Before the truck leaves your driveway in Longwood, both manufacturer warranty layers are registered in writing under our Keystone Standard, and the durations are stated plainly on your paperwork. That’s not a marketing promise. It’s how we’ve done business for over four decades, and it’s why Longwood homeowners keep our number.

Our Window Replacement Services in Longwood

Historic Window Restoration

Longwood’s National Register-listed Historic District changes the rules for window replacement. Wood-frame homes dating to the 1870s and 1880s fall under Florida SHPO historic-preservation review, and standard off-the-shelf double-hung replacement windows simply do not pass muster. The original true-divided-light profiles and narrow-rail muntins on those windows were built to a dimension that modern mass-produced units abandoned decades ago. We source custom-milled sashes, jamb extensions, and casing profiles that match the original millwork, and we coordinate directly with your preservation architect before ordering. This is a Longwood-specific specialty. Homeowners in Lake Mary or Casselberry don’t carry this same preservation burden, and a contractor who treats a West Church Avenue Victorian like a Wekiva Springs Road ranch will cost you months and money. We won’t.

Full Frame Replacement

Full frame replacement is the correct call when the existing window frame is rotted, out of square, or when you’re changing window styles or sizes in a Longwood home. This is especially common in the 1970s through 1990s concrete-block subdivisions along SR 434 and Wekiva Springs Road, where original aluminum frames have oxidized and warped after 30 to 50 years of Florida sun and rain. We remove the old frame down to the rough opening, address any water damage we find in the surrounding framing, and set the new window square and true. Full frame work in Longwood runs $1,100 to $2,300 per opening depending on size, frame material, and whether impact glazing is required. We measure every opening twice and quote manufacturer lines side by side on paper, so you see exactly what you’re paying for before any order is placed.

Insert Window Replacement

For homes with structurally sound frames, an insert replacement is the faster and more economical route. This approach sets a new energy-efficient window unit inside the existing frame, which typically avoids disturbing interior trim and exterior siding. It works well for many 1980s and 1990s Longwood homes where the frame itself is still solid but the glass is fogged, the balance system failed, or the weatherstripping has turned to powder. Insert replacement in Longwood generally runs $650 to $1,450 per window installed. Most insert jobs in Longwood are completed in a single visit, provided the windows are in stock or short-lead. We’ll tell you honestly whether your house is a candidate for inserts or needs full frame replacement before we quote either one.

Storm Window Replacement

Longwood sits outside the High-Velocity Hurricane Zone, but every replacement window still must carry Florida Product Approval, and the permit process is non-negotiable. Homeowners moving into older homes sometimes discover the previous owner installed non-compliant windows without a permit, and that becomes their problem at the next storm or sale. We install code-compliant storm windows and impact-rated units from manufacturers like PGT and CGI, and we pull the permits and schedule the inspections. If you’re in a 1980s home on the north side of Longwood near the Wekiva River basin, the combination of afternoon thunderstorms and high humidity means your existing storm protection gets tested every summer. We make sure what’s on your house actually meets the current Florida Building Code, not just what passed in 1985.

Energy-Efficient Upgrade

Replacing single-pane aluminum sliders with Low-E, argon-filled insulated glass units is the single biggest energy improvement most Longwood homeowners can make to their existing house. Longwood gets 50-plus inches of rain a year, intense UV exposure, and dramatic thermal cycling between the heat of afternoon and the cooler overnight hours. That combination degrades dual-pane seals and aluminum frame finishes faster than in drier Sun Belt cities like Phoenix. An energy-efficient upgrade typically runs $550 to $1,150 per window for inserts in Longwood, and the difference in cooling loads is measurable. We quote manufacturer lines from ECO Window Systems and ES Windows side by side, with the U-factor and SHGC ratings printed on the quote so you can compare actual performance, not just price.

Trusted Brands We Service in Longwood

TruePane is an authorized installer for more than a dozen manufacturer lines, and we regularly work with CGI, ES Windows, ECO Window Systems, and CWS on Longwood projects. When a Longwood homeowner has a warranty claim or needs a matching sash for a specific product line, we can usually order replacement components faster than a general contractor who only touches two brands a year. We stock common replacement hardware and insulated glass unit parts locally, which means when a 1980s aluminum slider loses its latch or a 2000s double-pane develops a fogged seal, we’re not waiting a week for parts from a distribution warehouse in another state. We also register both manufacturer warranty layers in writing on every single job, so if something fails in year two or year ten, you have a documented path to resolution, not a phone number nobody answers.

Common Window Replacement Problems We See in Longwood Homes

• Oxidized aluminum frames on 1970s-1990s ranch homes. The original aluminum sliders along Wekiva Springs Road and the SR 434 corridor expand and contract with every hot afternoon and cool night. After 30 to 40 years, the frames warp, the tracks bind, and the latch hardware simply stops aligning. The glass is fine. The frame is done.
• Seal failure and fogged glass in dual-pane units. Longwood’s UV intensity and annual rainfall are hard on insulated glass units. Argon-filled windows that should hold a U-factor around 0.30 degrade toward single-pane performance within 10 to 15 years in this climate. Once the seal fails, the only permanent fix is replacing the IGU or the entire sash.
• Historic District replacements that stall mid-project. This is a Longwood-specific problem. A homeowner starts what looks like a straightforward double-hung replacement, then discovers the home falls within the National Register boundary. Standard replacement frames lack the narrow-rail, true-divided-light profile and jamb depth required by SHPO review. The project stops. We see this often enough that we now check the historic boundary map on every quote east of Ronald Reagan Boulevard.
• Permit surprises on non-compliant replacement windows. Longwood falls under full Florida Product Approval requirements even though it’s outside the High-Velocity Hurricane Zone. Homeowners sometimes discover past replacements were done without permits or with non-approved products, which becomes a liability at sale time or when an inspector gets involved. We handle the permit pull and inspection scheduling on every job, so there’s no discovery waiting for you.

Pricing for Window Replacement in Longwood, FL

Why Our Customers in Longwood Trust Us

We recently replaced a fogged, seal-failed insulated glass unit in a 1920s Craftsman on West Church Avenue inside the Historic District. The homeowner had already talked to two other companies that quoted standard replacement sashes. Neither would fit the original true-divided-light muntin profile. Our team matched the original muntin dimensions, custom-milled jamb extensions to preserve the narrow-rail double-hung look, and coordinated directly with the homeowner’s preservation architect before ordering from Marvin. The fixed written quote held through the three-week custom order lead time. No surprises when the sashes arrived, no change order halfway through. That’s the kind of work this district demands, and frankly, it’s the kind of work we like doing. Dale Kessler started this company on the principle that out-of-true installs and voided warranties are problems worth fixing permanently. We’ve kept that standard since 2008, and we bring it to every Longwood job, historic district or not.
