Panel-house refurbishment
Series-aware refurbishment of Estonia’s panel stock — khrushchyovka, brezhnevka, Series 111, and modern prefab.
Approach
Panel-house refurbishment starts with identifying the series. Each series — khrushchyovka, brezhnevka, 111, 1-464A, or modern prefab — sets its own limits: which partitions may come out, how thick insulation can go, which joints fail first.
We do not apply a "standard solution" before the building is walked. Facade insulation system, riser replacement sequence, and balcony glazing detail all follow the specific building’s condition — not a catalogue.
Workflow
Six stages for a panel-building refurbishment.
Series and condition identification
Site walk, series confirmation, load-bearing-panel diagram, moisture and wall-condition record.
Technical quote
A series-specific technical note is attached to the quote — the client sees clearly what the series allows and what it does not.
Disciplined strip-out
Partitions removed only after load-bearing verification. Sanitary units stripped in sequence so risers are not cross-damaged.
Facade works
Insulation (ETICS or ventilated), joint sealing, window replacement in batched lots.
Interior works
Interior fit-out, drywall, floor substrate and install, plumbing, electrical.
Documented handover
Condition report (e.g. new façade U-value), warranty, series-specific maintenance guide.
Technical standards
Outcome on panel stock is driven by technical discipline — not brand names.
Joint sealants
Two-component polyurethane systems rated for Estonia’s -30…+35 °C range without cracking.
Facade insulation
EPS or mineral wool per fire class and building height; A2-class required above eight floors.
Interior moisture barrier
End walls and wet-room backs receive a moisture barrier before tiling — not "if budget allows".
Window install standard
RAL install with three-layer sealing (inner vapour, central thermal, outer wind). Straight PU foam does not qualify.
What you receive at handover
- Series-specific technical report (before/after)
- Facade insulation system specification with U-value
- Window and door install protocol (RAL protocol)
- Joint-seal photo archive by stage
- As-built drawings for utilities (heating, water, ventilation)
- Twelve-month written warranty plus five-year facade system warranty
