Choosing a reliable builder starts with three checks: is the company active in the register, does it have the competence required for this work, and can it describe the work in writing. If all three are in order, compare at least three quotes based on the same job description and agree everything in writing.
A good price request answers four questions: what needs to be done, where, when, and what condition it's currently in. Add measurements or the number of rooms, a couple of clear photos, and note what matters to you (deadline, materials, dust-free work). You don't need to propose a price yourself.
Compare quotes line by line, not by total sum: scope of work, materials, preparation, waste removal, VAT, start date, duration, and warranty. If two quotes differ significantly, the reason is almost always scope or assumptions — ask for clarification before deciding.
The price of tiling work is mostly affected by the surface area and pattern complexity, tile size, condition of the base surface, need for waterproofing, and the number of cuts and details. Before ordering, check the levelness and moisture of the base surface and whether the old covering has been removed.
Changing an electrical installation, panel work, adding new circuits, and connections to the permanent installation must be ordered from a competent electrician. Safety and later verifiability matter more than the price difference — always ask for proof of competence and a written overview of the work.
In case of a leak, first shut off the water (the apartment's shutoff valves or the riser shutoff), limit the damage, notify neighbours and the building manager, and photograph the situation before cleaning up. Only then order the repair — documentation is needed both for the repair and for insurance.
Extra costs almost always come from three sources: conditions revealed once things are opened up, client-side changes during the work, and side jobs left out of the quote. You can keep them under control with a precise job description, a written change-order process, and a reasonable reserve.
Acceptance means systematically reviewing the work in daylight, recording defects in writing with a deadline, and receiving documents: warranty, user manuals, a list of change orders, and the final invoice. Don't confirm acceptance until the list of defects has been agreed.
