Therma-Tru Impact Windows & Doors in Columbus: What to Know First
TruePane Windows & Doors installs, replaces, and services Therma-Tru impact windows and doors throughout Columbus as an independent Therma-Tru service provider. Most Therma-Tru impact jobs in Columbus take one to two days on site, and we quote fixed pricing in writing before any work begins so there are no surprise line items on the bill. If you own a Therma-Tru entry door or window system and it is binding, leaking, or simply not closing the way it used to, call (888) 635-0804 and a live person will pick up.
How Therma-Tru Products Fail - and How We Fix Them
Therma-Tru builds a solid door, but every product line has its weak points. Here is what we actually see on Therma-Tru impact windows and doors in Columbus homes, and what we do about it.
- Seal failure on Therma-Tru Classic-Craft and Fiber-Classic impact glass. Columbus swings from humid summers to dry, cold winters, and that cycle stresses the seal around insulated glass units. The tell-tale sign is fog or condensation between the panes that will not wipe off, and the fix is a new sealed unit, not a tube of caulk around the sash. We replace the IGU and re-glaze the sash so the door or window keeps its impact rating.
- Sill rot and corner seal failure on Therma-Tru entry systems. Even fiberglass doors sit on a sill that takes standing water from Columbus rain and snowmelt. When the corner seal on the bottom rail of an impact door fails, water wicks up into the frame and rots the sub-sill before you ever see it inside. We pull the door, replace the rotted sub-sill with pressure-treated stock, re-flash the opening, and reset the door so water sheds away from the threshold instead of under it.
- Hinge sag on heavy Therma-Tru impact doors. Impact-rated glass is heavier than standard glass, and a Therma-Tru door with impact glazing puts real strain on its hinges and frame anchor points. The symptom is a door that rubs the latch side in July and swings open on its own in January because the rough opening has shifted with the frost line. We re-shim and re-anchor the frame, then re-hang the slab so the reveal is consistent top to bottom. A window that fits right shouldn’t need caulk to do the work the frame was supposed to do.
- Weatherstripping compression on Therma-Tru sliding patio doors. The sweep and jamb seals on Therma-Tru impact sliders compress over time, and once they lose their spring, the door drafts and water finds its way past during a hard Columbus storm. We stock OEM-profile weatherstripping for most Therma-Tru slider lines and replace the full run, not just the piece that looks worn.
- Failed multipoint lock assemblies on Therma-Tru entry doors. The multipoint lock on a Therma-Tru impact door is a good system until one roller or hook gets out of alignment, and then the whole assembly binds and the deadbolt will not throw. We see this often on doors installed by crews that did not re-check the strike alignment after the first season of settling. We rebuild or replace the lock assembly, align the strikes, and test the throw until it runs smooth.
Our Therma-Tru Impact Windows & Doors Process
Here is how a Therma-Tru job runs when you call TruePane Windows & Doors in Columbus, from first call to final walkthrough.
- 1
Call and diagnosis. You call (888) 635-0804 and describe what you are seeing. A live person answers and schedules your appointment. We ask about the door or window model, the year it was installed, and exactly where the problem shows up.
- 2
On-site measurement and inspection. A background-checked, uniformed technician shows up when we say. We measure every opening twice, inspect the frame, the rough opening, the weatherstripping, and the glass. We look at the exposure, the sill, the flashing, and how the sun hits the elevation.
- 3
Written quote side by side. We quote OEM Therma-Tru parts and quality aftermarket alternatives on paper, side by side, with the difference stated plain. You see exactly what you are paying for, and the price we write is the price on the bill.
- 4
The work itself. We pull the old unit or repair in place as needed. For replacement, we set the frame level and square, shim it tight, anchor it, flash it, and insulate the reveal. For impact glass, we re-glaze with the correct sealant and verify the rating label is preserved on any replacement sash.
- 5
Testing and adjustment. We cycle the door or window repeatedly, check the reveals, throw the locks, and run water on the exterior. If the pane is not true, the job is not done.
- 6
Warranty registration and cleanup. Both manufacturer warranty layers are registered in writing before the truck leaves the driveway. That is The Keystone Standard, and it applies to every Therma-Tru job. We haul the old unit, sweep the floor, and walk you through what we did.
What Therma-Tru Impact Windows & Doors Costs in Columbus
Pricing for Therma-Tru impact windows and doors in Columbus breaks down like this, and while every job is quoted after we see the opening, these numbers will give you an honest place to start.
- Glass-only replacement for a Therma-Tru impact door or window: $400-$900 per insulated unit, depending on size and whether it is low-E impact-rated glass.
- Weatherstripping and seal replacement on a Therma-Tru entry or slider: $150-$400, including the OEM-profile material.
- Multipoint lock repair or replacement: $250-$550, depending on the assembly and whether new strikes need to be routed.
- Full-frame impact window replacement (Therma-Tru compatible): $900-$2,200 per opening installed, depending on size, frame material, and the impact rating required.
- New Therma-Tru impact entry door, fully installed: $3,500-$7,500, including frame, sill, hardware, and finish work.
What moves the price: the condition of the rough opening, whether we find rot once the old unit comes out, the size of the glass, and whether the opening needs re-flashing. We quote fixed prices up front, and we do not change the number after the work starts unless you approve a change in scope.

Why Columbus Homeowners Call TruePane Windows & Doors for Therma-Tru Work
We have been serving Columbus since Dale Kessler opened the shop in 2008, and the rule on the whiteboard has not changed: if the pane is not true, the job is not done. Dale grew up in Clintonville, learned glazing and rough framing at Columbus State, and has been setting windows and doors in central Ohio for close to three decades. That is the difference between a crew that has seen a Therma-Tru frame twist in a Columbus winter and one that is reading the manual on your front step.
Every Therma-Tru job is covered by the Done Right Promise. If it is not done right, we make it right, with no paperwork fights and no fine print that covers neither. We also carry and service PGT, CGI, CWS, and ES Windows brand impact products, so if your Therma-Tru unit is beyond reasonable repair, we can quote you a comparable impact-rated replacement with the same warranty registration standard. A live person answers the phone 24 hours a day, 7 days a week. We will be there when we say.
FAQs
It depends on who does the work and what parts they use. Therma-Tru’s warranty can be voided by unauthorized modifications, so we register both manufacturer warranty layers in writing on every job and use OEM or warranty-compatible parts. That is the only way to keep your coverage intact.
Most Therma-Tru repairs are completed in a single visit, and a full entry door replacement typically takes one day. Larger multi-opening jobs are quoted with a written schedule before we start.
Usually the rollers are worn or the track has settled out of level, especially in Columbus where frost heave and summer humidity work on the framing. We adjust or replace the rollers, re-level the track, and lubricate the run so the door moves like it should.
Yes. When a job in Columbus requires a permit, we pull it, schedule the inspection, and make sure it passes. That is a square deal, and it is part of every quote we write.
