What the work looks like in the app
Real screens from a sample apartment estimate, with made-up client details.
The app is in Polish today, so the screens below are Polish. An English version is in preparation.
You describe the job, AI sets up the project
Enter what needs doing: m² of flooded rooms, the drying time, drying under the floor, meters of damp wall or m² of mold. AI sets the items and the quantities, and you see the amounts straight away.
- Every parameter AI set is marked
- Click it and correct it before the estimate goes to the client
Labor with working time
Each item is a rate with equipment and agents, and each category has an amount and the number of crew workdays. You decide whether the client sees the time. Drying, walls and mold, and removal are in separate categories. Items you repeat can be saved in your own library (in PRO for companies) and added to your next project.
You decide what the client sees
Choose what goes into the estimate and which details to show: items, completion time, price notes. The PDF goes out with your company's details.
Sharing and export
Access for a chosen person: read, edit or admin. The public read-only link is in PRO for companies. Export to PDF and XLS, and a company account can also upload its own price list from an .xlsx file.

What the calculator gives a drying company
Net starting prices and 8% VAT, since drying is renovation work in a residential building. Commercial premises and non-residential buildings usually have 23%—check the rate with your accountant; you change the rate and every price.
Drying per m² and week
Condensation dehumidifiers, heaters, measurements and servicing per m² of floor and each week of work. With no time in the description, the template uses 2 weeks.
Subfloor drying
Water under the screed or in the insulation: holes in the floor, turbines and dehumidifiers: a start-up fee and a price per m², with the holes plugged.
Damp walls
Crystalline injection against rising damp per lin. m of wall (wall up to 40 cm; for a thicker one you change the rate) and breaking off damp plaster down to the wall per m².
Mold and odor
Mold removal from walls or ceilings with an agent per m², without breaking off or painting, and ozone treatment of an apartment or house up to 60 m² as a service.
Moisture report
The inspection and on-site moisture measurement is priced at 0. A moisture measurement of the walls and floor with a report, e.g. for an insurer or the building manager, is an optional item you add.
Bulk bag removal
Debris and wet materials in a bulk bag (approx. 1 m³) with pickup, per unit.
Sample jobs
Typical jobs and how the calculator sets them up. You set your own prices.
16 m² room after a flood, a week of drying
The template works out condensation drying for 16 m² of floor for one week.
50 m² apartment flooded from the one above
With no time in the description: the template works out drying for 50 m² for 2 weeks, ozone treatment and a moisture measurement with a report.
Subfloor drying of a bathroom and hallway
After a plumbing failure: the template works out subfloor drying of 30 m² with the holes plugged.
Damp basement walls
30 lin. m of injection, breaking off 40 m² of plaster and 20 m² of mold removal: the template works out each job separately and the removal of 2 bulk bags.
60 m² for 3 weeks and 12 m² under the floor
After a major flood: the template works out drying for 60 m² for 3 weeks and subfloor drying for 12 m².

Works with the other tools
Data moves with one click. Each tool also works on its own, and nothing is saved without your say-so.
Contract and estimate with the project data
Open the document generator from the project menu. Client, address, scope and amounts are already in. Send the contract to the client to sign online, and after the job prepare an acceptance report, plus an addendum when the scope changes.
Open
Acceptance report after the job
Below the contract in the generator, choose a work acceptance report or a contract addendum. The parties, address and contract date carry over on their own, and the client signs the report on the screen.
- Chrome extension
A product from a shop straight into the estimate
The Chrome extension takes what the shop gives—usually the name, photo and price—from the shop page into the project and room you choose. Whatever the shop does not give, you select on the page and say what it is—a name, a price, a dimension, a color, a finish, a material, a catalog number, the manufacturer or the supplier. In October 2026 we checked it on 24 Polish online shops; it is not limited to selected partners.
Open - Document generator
A QR code on the contract from the generator
The PDF ends with a QR code. Your client checks with a phone that the PDF file is the same document as the printout.

Questions about quoting drying
How is drying after a flood worked out?
Per m² of floor of the rooms being dried and per week of dehumidifier work. The default is 2 weeks. Drying the screed from below (subfloor drying) is a separate item: a start-up fee and a price per m².
Is there a moisture report for the insurer?
Yes, a moisture measurement of the walls and floor with a report is an optional item. The full damage quote for the insurer comes from the damage assessment calculator.
What about a damp basement wall?
Crystalline injection against damp per lin. m of wall (wall up to 40 cm), breaking off damp plaster and mold removal per m², bulk bag removal per unit.
How long does drying after a flood take?
Usually 1–3 weeks. You set the time after measuring the moisture. Without a time in the description, the template counts 2 weeks.
Is there ozone treatment after a flood?
Yes. Ozone treatment of an apartment or a house up to 60 m² is a service per unit.
