Phase 1: Technical visit and initial assessment

Everything starts with a site visit. A Constroleum technician visits the property, evaluates its structural condition, existing installations, layout possibilities and areas of concern (damp, cracks, installations to be replaced). If the client cannot be present, we coordinate the visit with the real estate agent or a representative and present the full findings by video call.

Result of this phase: initial technical report and preliminary cost estimate within 48 hours.

Phase 2: Project and detailed budget

Once interest is confirmed, we prepare a detailed budget broken down by trade: demolition, installations, finishes, joinery, sanitary ware, kitchen, painting. Each item includes the cost of materials and labour. The budget is accompanied by a weekly construction schedule.

"The budget signed with Constroleum is the final price. We do not apply additional charges for management, coordination or ordinary construction contingencies. We only invoice modifications expressly approved by the client in writing."

Phase 3: Permit processing

Once the budget is approved and the contract signed, we begin processing the necessary permits. In the most common case — full renovation of an apartment without modifying the façade or structure — the prior notification process (egyszerű bejelentés) is completed in 10–15 days.

Phase 4: Construction execution — typical workflow

Phase 5: Quality control and handover

Before calling the client for the handover visit, we carry out an internal quality control check on all items: we verify that all installations are working, review finishes and correct any defects found. The handover is documented with a photographic checklist signed by both parties.

Phase 6: After-sales and warranty

Our relationship with the client does not end at handover. We are available throughout the warranty period to resolve any incident. We offer an annual technical review of the property on request — especially useful for owners who do not reside in Budapest.
