Fast, Reliable Window Replacement Across Pittman
Window replacement in Pittman typically runs $700-$1,400 per opening for a standard insert on a wood-frame home, and $1,200-$2,600 per opening when full frame replacement is required because the rough opening has rotted or the size must change. Most Pittman jobs involve acreage properties, Lake County permits, and septic setback rules that urban window companies never have to think about. TruePane Windows & Doors has navigated those constraints on rural lots throughout the St. Johns River corridor for years, and a live person answers when you call (813) 320-9346.
We measure every opening twice, check the rough framing before we quote, and put the permit path in writing so you know whether your windows can be upsized or must stay exactly as they are. If you live off Lake Norris Road, in the Paisley area, or anywhere along County Road 42, we know the haul distances, the drainage patterns, and the county sign-off requirements that shape your project.
Why TruePane Windows & Doors Is Pittman’s Preferred Window Replacement Company
Pittman is unincorporated Lake County, and that changes how window work gets done. There is no city building department to call. Every permit moves through Lake County, and on acreage parcels the health department gets a say when a window opening faces a septic drainfield. We know that before we write your quote, not after the old sash is pulled. Dale Kessler founded TruePane in 2008 on a rule he still keeps on the whiteboard: if the pane is not true, the job is not done. That rule fits Pittman, where a fogged 1968 jalousie window is rarely just a glass swap once the rough opening is exposed.
We stand behind the work. Every job carries the Done Right Promise and The Keystone Standard: both manufacturer warranty layers registered in writing, durations stated, before our truck leaves your driveway. No arguing about what is covered. No fine print that covers neither. When a homeowner off Lake Norris Road calls about a binding sash or a sill that has gone soft from river humidity, they get a background-checked, uniformed technician who measures twice and quotes manufacturer lines side by side on paper.
TruePane is an authorized installer for more than a dozen manufacturer lines, including, PGT, and CGI. That matters in Pittman because rural homes often need specific frame depths, custom jamb extensions, or impact-rated glazing that a single-brand shop cannot supply. We bring the right window for the opening, not whichever unit is on the truck.
Our Window Replacement Services in Pittman
Full Frame Replacement
Most older Pittman homes need full frame replacement, not an insert. The original windows are frequently single-pane aluminum or jalousie units set into wood rough openings that have absorbed decades of St. Johns River corridor humidity. Once the old sash comes out, we often find sill rot, separated jambs, or openings that were patched with foam and caulk instead of properly flashed. Full frame replacement for a Pittman wood-frame home typically runs $1,200-$2,600 per opening, including new framing lumber, butyl tape flashing, and a fusion-welded frame that meets Lake County wind-load requirements.
On a job off Lake Norris Road, our crew pulled a 1968 single-pane awning and found the rough opening so rotted the jamb had separated from the king stud. We reframed with pressure-treated lumber, flashed the sill with butyl tape, and set a Simonton insulated glass unit with low-E glass and argon fill. The homeowner’s fogged, rattling sash is now a sealed, energy-rated window that will not leak when summer thunderstorms roll through.

Storm Window Replacement
Pittman sits inland, but northeast Florida’s hurricane track exposure still puts design wind-speed requirements on every window opening under Florida Building Code. Many of the original windows on Pittman’s 1960s and 1970s rural homes carry no wind rating at all. Storm window replacement in Pittman usually falls between $900 and $1,800 per opening when the existing frame is sound and the opening will accept a rated unit. When the frame is compromised, we recommend full frame replacement with impact-rated or high-design-pressure glazing so the permit passes the first time.

Energy-Efficient Upgrade
Relative humidity along the St. Johns River corridor runs above 80 percent even in winter. That persistent moisture kills seals in cheap insulated glass units and drives condensation into old aluminum frames. An energy-efficient upgrade in Pittman typically runs $750-$1,500 per window for a low-E, argon-filled insert, assuming the rough opening is dry and the frame is structurally intact. Homeowners with older single-pane units see the biggest jump in comfort: sealed frames stop the drafts, and low-E coatings cut the solar gain that makes west-facing rooms brutal in July and August.

Insert Window Replacement
When the existing frame is square, dry, and free of rot, an insert replacement is the most economical route. Insert window replacement in Pittman generally runs $700-$1,400 per opening, and most jobs finish in a single visit. We measure every opening twice before ordering so the jamb depth matches and we are not doing a second trip because a flange was ordered wrong. That matters on rural lots where a return trip means another long haul from the material yard.

Trusted Brands We Service in Pittman
We carry and install Simonton, PGT, and Ply Gem, and we quote side by side on paper so you see exactly what you are buying, line by line. For Pittman homes with septic setback constraints that prevent enlarging an opening, we often recommend Simonton’s fusion-welded vinyl frames because they let us hit wind-load ratings without changing the rough opening size. For homeowners who want coastal-grade protection despite being inland, PGT impact units are a common upgrade. Our team pulls the specs against your Lake County permit requirements before recommending a line, so you are not paying for a rating you do not need or missing one the county requires.
Common Window Replacement Problems We See in Pittman Homes
- Septic setbacks block window upsizing. Lake County requires a health department sign-off when an enlarged window opening falls on the side of the home facing a septic drainfield. If the setback does not allow the larger opening, the window must stay the exact same size. We check that before we quote, not after the old window is pulled.
- Rotted rough openings behind decades-old caulk patches. Original jalousie and single-pane awning windows on Pittman’s 1960s and 1970s homes were often foamed and caulked rather than replaced. Once the sash is out, the rough opening frequently shows sill rot and separated jambs that turn a window swap into a framing job.
- Open-lot grading pushes sheet flow under doors and into window rough openings. Slab homes on graded acreage let rainwater run toward the foundation. Over the years, that water weeps into the rough opening and rots the sill from the inside, where it stays hidden until the old window is pulled.
- Long material hauls make mistakes expensive. Pittman is a long drive from Winter Garden and Mount Dora material yards. A mis-ordered jamb depth or a missing roll of flashing tape can add a full day to a rural replacement. We check the order twice before the crew leaves, and we bring our own equipment so the job is not waiting on a rental yard.

What moves the number in Pittman more than anything is the condition of the rough opening and whether Lake County setbacks allow the opening to change size.

We scope the framing, the permit path, the drainage, and the haul before we give you a written, line-item quote, so the number you sign is the number you pay.

FAQs - Window Replacement in Pittman
Yes. Pittman is unincorporated, so all window replacement permits go through Lake County, not a city building department. If the replacement changes the rough opening size, and that opening faces a septic drainfield, the county health department must sign off before the permit issues. If the setback will not allow the larger opening, the window must stay the same size. We check the setback and the permit path before we quote, so you know whether your window can be upsized or must remain as-built. Call (813) 320-9346 for an exact assessment on your parcel.
Because decades of St. Johns River corridor humidity rot the wood rough openings behind the original single-pane or jalousie windows. Once the old sash is pulled, we regularly find sill rot, separated jambs, and openings patched with foam and caulk rather than properly flashed. A full frame replacement rebuilds the opening with pressure-treated lumber and butyl-tape flashing before the new unit is set, which is the only way to meet Lake County wind-load requirements on those older openings.
Yes. Florida Building Code design wind-speed requirements apply throughout northeast Florida, not just on the coast. Older Pittman homes often carry no wind rating on their original windows, so upgrading to an impact-rated or high-design-pressure unit is legal, permitted, and often the best way to satisfy the code review. The county permit office cares about wind-load compliance, not flood zone designation, for window openings. Call (813) 320-9346 and we will pull the spec for your opening.
If the fog is between the two panes of an insulated glass unit, the seal has failed and the unit will not clear up on its own. That is a replacement, not a repair. In Pittman’s high-humidity climate, seal failure moves fast once it starts: the fog gets heavier each season, condensation creeps into the frame, and the wood or composite around the unit absorbs moisture. A rattling sash or a sill that feels soft at the corner usually means the opening itself is failing too. Our team will inspect the unit and the rough opening and tell you whether a sash swap is enough or the whole frame needs to come out. Estimates are free.
We serve all of Pittman, from the Lake Norris Road acreage to the parcels along County Road 42 and into Paisley, and our crews bring their own scaffolding, saws, and flashing materials. We do not rent equipment at the job site, and we check every order twice before the crew leaves because a forgotten roll of butyl tape on a rural lot means a long second trip. The haul distance from the material yards is priced into the quote up front, so there is no surprise travel line item on the bill.
