On-site inspection on request
Real cases. Documented results.
Each project is different. The approach is always the same: identify the real cause, define the right fix, and control the execution until the result is stable.
Mold returning despite repeated treatments
Situation
Ground-floor apartment in an older building in Sofia. Bedroom with limited ventilation.
Problem
The mold kept coming back. Several treatments had been done — each time it looked fixed, but only temporarily. Health symptoms started to appear. The real cause had never been addressed.
What changed
We stopped treating the surface. Instead, we identified the actual source — moisture combined with structural weak points — and rebuilt the affected areas accordingly.
Result
No visible recurrence after remediation. Stable indoor climate. For the first time, the problem was addressed at its source — not covered.
Property losing value due to hidden structural issues
Situation
Holiday apartment in Bansko, unused for several years.
Problem
Outdated surfaces were obvious — but the bigger issue was hidden: wear, inefficiencies, and structural weaknesses that made the property unattractive for rental.
What changed
We didn't just renovate visually. We reworked the apartment from a usability and longevity perspective — layout, materials, and functional details.
Result
Significantly higher rental appeal. Stronger pricing potential. A property that works again — not just looks better.
Moisture damaging the building from inside
Situation
Older single-family house without modern sealing systems.
Problem
Moisture rising through multiple walls. Damaged plaster, persistent damp air, declining living quality. This was not a cosmetic issue — it was structural.
What changed
We identified the exact source of moisture and implemented proper sealing solutions before restoring affected areas.
Result
Dry walls. Stable indoor conditions. Long-term protection of the building — not temporary repair.
Constant noise affecting daily life
Situation
Apartment located directly on a high-traffic road in Burgas.
Problem
Continuous noise — especially at night and during work hours. Home office almost impossible.
What changed
We developed a targeted sound protection solution — combining wall and window adjustments to reduce external noise effectively.
Result
Noticeably quieter environment. Usable living and working space again. Significant improvement in quality of life.
Property not usable due to multiple issues
Situation
Rental apartment in Varna, vacant for a longer period.
Problem
Combination of moisture, mold, and general deterioration. The apartment was not rentable in its condition.
What changed
We approached the project as a system — removing root causes of moisture, eliminating mold, and fully restoring the property.
Result
Fully functional, rentable apartment. Improved property value and long-term usability restored.
If your property has a recurring moisture, mold, renovation, noise or value-risk problem, we can assess the situation and define a practical solution path.
