Sliding glass door replacement is one of those jobs where the quotes homeowners collect can be wildly different, and the reason is usually that they are not comparing the same door. Here is what goes into a replacement quote in Tampa Bay, what drives the number, and how to tell whether you need a new door at all.
The short answer
A replacement is quoted by the opening, after someone measures it and looks at the sill. The door you choose, the condition of the opening and whether the glass is standard, low-E or impact rated are the three things that move the number the most. Hurricane impact sliding doors sit at the top because the glass, frame and anchoring are all heavier. We give a written, flat quote after a free in-home measure, and that number is final.
What you are actually paying for
A replacement quote has five parts, and the door itself is only one of them.
The door. A 6-foot two-panel aluminum door with clear tempered glass is the simplest unit and the most common in older Tampa homes. Eight-foot-tall doors, three and four-panel doors, vinyl frames and low-E insulated glass all step the job up. Laminated impact glass in a reinforced frame is the top of the ladder.
The opening. A door that fits into a clean, square, dry opening is a one-day job. A rotted wood buck, a cracked slab at the sill, or an opening that is out of square by an inch adds carpentry before the new door can go in. This is the surprise that shows up on install day when nobody measured properly, so make sure whoever quotes you actually pulls the trim and looks.
The permit. Replacing an exterior door is permitted work in Hillsborough, Pinellas and Pasco. A legitimate quote includes the permit fee and the inspection visit. If a quote skips the permit to come in cheaper, that is a problem for you, not the installer, when you sell the house or file an insurance claim.
The install. Removal and haul-away of the old door, flashing the opening, setting the sill level, anchoring to the manufacturer pattern, sealing the perimeter against wind-driven rain, and adjusting the rollers and lock. Cheap installs skip the flashing. You find out the first summer.
The extras. Custom frame colors, keyed handle sets, heavy-duty rollers, and condo-specified design pressures each add a little.
Standard, low-E or impact?
If your lanai already has shutters you are happy to use, a standard aluminum or vinyl door is the sensible choice and the simplest quote.
If the door faces west and the room bakes every afternoon, low-E insulated glass is worth the step up. It reflects heat, cuts glare and helps the air conditioner keep up in August.
If you are tired of putting up shutters every time a storm turns toward the Gulf, or your insurance carrier is asking about opening protection, go straight to an impact sliding door. It costs more up front, but it protects the house every day, cuts noise, and usually earns a wind mitigation credit once every opening is rated.
When you do not need a new door
This is the part most door companies skip. If the frame and sill are sound, the door almost never needs replacing. Doors that are heavy, grinding or off the track need new rollers, a flat-priced single-visit job. A fogged or cracked panel needs glass replacement, quoted per panel. A lock that will not catch is a small repair, not a new door.
Replace the door when the frame is corroded through, the sill leaks every storm, the glass is fogged in more than one panel, or you want impact glass. Otherwise, repair it and keep the difference.
What to ask before you sign
- Is the permit and inspection included?
- What is the Florida Product Approval number for the door?
- Will you flash the opening, and how?
- What is the warranty on labor, separate from the manufacturer warranty?
- Did you measure the rough opening or just the old door?
