CHANGE FROM PREVIOUS

On the basic metrics alone, the score was 78.3 and the rank 1. The score is now 71.2 and rank 2 (▼ 1 place). The difference comes from buying motives: they measure what the buyer asks before deciding.

AI SUMMARY · AI ALGORITHM · 20.8.2026

Consti on yksi Suomen suurimmista linjasaneerausurakoitsijoista, ja sen putkiremonttisivut ovat poikkeuksellisen läpinäkyvät: kerrostalon hintahaarukka 500-1200 euroa/m2, menetelmävaihtoehdot, asuntokohtainen kesto 4-12 viikkoa sekä RALA-pätevyys ja referenssit kerrotaan avoimesti. Suurin puute on operoivan yhtiön Y-tunnuksen puuttuminen sivustolta ja se, ettei erillistä työn takuuaikaa ilmoiteta.

Strengths

  • The price range for a block-of-flats pipe renovation is stated openly online: a price estimate of 500-1200 euros per apartment square metre, and the factors affecting the price (size, structures, scope of bathrooms) are itemised
  • Menetelmävalikoima kuvattu kattavasti: perinteinen linjasaneeraus, hybridiremontti, kevytremontti ja viemareiden sukitus, ja asuntokohtainen kesto 4-12 viikkoa kerrottu
  • Laadunvarmistus todennettavissa: RALA-pätevyys, Luotettava Kumppani ja Avainlippu esillä, yli 500 toteutettua putkiremonttia ja julkiset referenssit

Areas to improve

  • The operating company or Business ID is not stated on the website, although the contracting partner's company is essential information for the housing company
  • Putkiston käyttöikä (jopa 50 vuotta) kerrotaan, mutta erillistä työn takuuaikaa vuosina ei mainita
  • There is no FAQ section or chat support
