Sliding Glass Door Replacement Cost Estimator

This prices a new sliding glass door, not a repair. Start with the size of the opening, say whether the address needs impact-rated glazing, and it gives you the typical range before measuring, built from the replacement figures published on the pricing page.

Before you use it, the honest framing: replacement is the last resort in this trade, not the first. A door that drags, jumps, will not lock, or has fogged glass is nearly always a few hundred dollars of parts away from working properly again, and the repair cost estimator is the tool for that. Replacement is right when the frame has failed rather than the hardware: a sill corroded through so water is going into the wall, a jamb that has separated, or an opening racked far enough that nothing sits square. It is also the right call when a homeowner wants impact-rated glazing on an oceanfront opening that never had it.

What each answer changes

  • Opening size is the biggest driver. The published range covers a standard 6 to 8 foot two-panel unit. Three- and four-panel doors are quoted rather than listed, because more panels bring more weight, more frame, and sometimes a header that has to be looked at. The multipliers here are for budgeting.
  • Glazing is where the coast shows up in the price. Under the 2021 South Carolina codes, exterior glazing in the wind-borne debris region has to pass the Large Missile Test of ASTM E1886 and ASTM E1996 or be protected by an approved covering, and impact-rated laminated units cost roughly double their non-impact equivalents. That is not an upsell, it is the code, and the permit and impact glass page explains how the region is defined and who decides for your address.
  • Permit does not move the number, and that is deliberate. What the answer changes is which office issues the permit and sets its fee: Horry County Code Enforcement for unincorporated addresses like Socastee and Longs, the city for Myrtle Beach and North Myrtle Beach, and Georgetown County or the town for Pawleys Island.

Send the estimate through the form and it comes to us; we measure the rough opening, confirm which side of the debris line the address sits on, and put a firm number in writing. If it turns out the frame is fine and the hardware is the problem, we say that instead, and it will cost you a fraction of what is on this page.

Estimator

What will a new sliding glass door cost?

Three questions. The range starts from the published price for a standard two-panel replacement and adjusts for the size of the opening and whether the coastal code requires impact-rated glazing.

Estimated installed range Typical Myrtle Beach pricing, before anyone visits

The permit answer does not change the estimate, because the fee is passed through at cost and shown as its own line on the quote rather than marked up. What it changes is which office the permit is filed with, and how long the job takes to start.

Send this estimate to the quote form

An estimate, not a quote. A replacement is only priced properly after the rough opening is measured, and three- and four-panel units are always quoted rather than taken off a table.

Frequently Asked Questions

Where do these replacement numbers come from?

The pricing page: $1,500 to $4,000 for a standard 6 to 8 foot two-panel replacement including removal of the old frame, flashing, setting, foam, and trim, and $3,000 to $6,000 for an impact-rated unit. The impact option adds exactly the difference between those two published ranges, so a standard two-panel impact door lands at $3,000 to $6,000 and nowhere else.

Why do three- and four-panel doors show a multiplier instead of a price?

Because the pricing page leaves them to a quote rather than publishing a range. More panels mean more glass, more frame, more weight, and often a structural header conversation. The multipliers here are a planning figure to help you budget, and the real number comes after the opening is measured.

Does the permit fee get marked up?

No. Where a permit applies, the fee is passed through at cost and shown separately on the quote. Horry County prices alterations from its adopted fee schedule and municipalities set their own, so the honest thing is to show you the actual receipt rather than bury a guess in the price.

Should I repair instead of replacing?

Usually, yes. Rollers, a track cap, a lock, and a glass unit together cost a fraction of a new door, and a 1980s aluminum slider with a sound frame can be made to glide again for a few hundred dollars. Replacement earns its money when the frame itself is gone: sill corroded through, jamb separated, or the opening racked.
