Sliding vs. French patio doors
Sliding doors are popular in newer Alpharetta and Forsyth subdivisions because they save space. French doors offer a classic look for historic intown homes but require precise alignment of the astragal and hinges to seal properly against Georgia storms.

Pricing, sources & disclosures+
Pricing source & methodology
Any dollar figures or price ranges shown on DoorGuide are educational reference points, not quotes. National typical mid-range bands are drawn from publicly available door installation cost research and adjusted for regional construction costs using a city-cost-index methodology. Ranges reflect professionally installed projects from licensed door installers, including standard frame prep and removal of the old door, not DIY, material-only, or handyman scopes. Actual pricing depends on door size and type, material tier, frame or sill condition, glass and hardware add-ons, and the installer you choose.

Estimates, not quotes
DoorGuide does not perform site visits, measure your openings, or inspect your framing. Any ranges, timelines, or scope descriptions are general guidance to help you compare materials and options before talking to an installer. A binding price requires an in-home measurement and assessment by a licensed professional.
Financing & APR disclosure
Door financing offers are typically advertised as a monthly payment. The figures that determine the true cost are the annual percentage rate (APR), term length, total interest, and any promotional-period terms (e.g., 0% APR for an introductory window that reverts to a higher rate). Always request the Truth-in-Lending disclosure in writing before signing. DoorGuide does not originate loans, broker credit, or make credit decisions. Financing is offered by third-party lenders subject to credit approval and applicable state law.
Licensing & warranty
Door installation is regulated at the state and local level, and some scopes (e.g., structural frame repair, egress or fire-rated door requirements) may require additional permits or licensed trades. Confirm that any installer you hire carries the appropriate licensing and insurance, and provides a written labor + materials warranty before work begins. Requirements differ by state and municipality.
Advertising & matching disclosure
DoorGuide is a free homeowner-education tool. When you complete the guided experience and opt in, we may match you with a vetted local door provider and may receive a referral or revenue-share fee from that provider if a project moves forward. Matching is optional and is never a condition of using the guide or viewing your door profile. DoorGuide is not an installer and does not perform door installation work.
