I love this App ! ### 5/5 — Piece of mind and an information advantage. *2026-07-09* This app doesn’t just help you understand the full problem you may be facing with a home repair. It also helps you understand the true cost of the repair. It’s better than a generic query on the internet because it’s basing the costs on your specific problem which you film, photograph and describe. Then it puts you directly in touch with contractors. It also stores your documents related to the repair so you can refer to everything on one place. Truly a useful application. ### 5/5 — Incredible *2026-07-09* Used this on a repair I needed done and it helped immensely. Saved me a ton of time figuring out what needs to be done, who to call, and what it should cost. Invaluable tool. Can’t believe it took until 2026 for something like this to exist. ## Frequently asked questions about Grainwork ### How does Grainwork estimate repair costs?
