Okonnaya kompaniya RS

Okonnaya kompaniya RS holds place 1 in the Saint Petersburg ranking with 9.9 out of 10 (calculated 14.10.2026). It reaches the maximum on four of the five criteria. Its installation warranty is long enough to hit the top of the scale, which is what separates it from the rest of the table.

Methodology

Why this score

  • Customer reviews. Ratings come from its listings on 2GIS and Yandex Maps, adjusted for the number of votes.
  • Price transparency. The price list states the unit it uses: per square metre or per opening.
  • Warranty. The website promises ten years on installation work, and that figure went into the formula.
  • Years in business. The legal entity was entered in Russia's state business register in spring 2017.
  • Response to criticism. Every author of a low rating over the past year got a reply on 2GIS. All companies are scored the same way, see the methodology.

What the company does

The menu of okna-remont-spb.ru covers PVC windows with installation, aluminium and timber frames, repair of any system and insect screens. Balconies have a section of their own: warm and cold glazing, finishing, insulation and soundproofing. Sliding portal doors and country-house projects are described separately. The profile catalogue lists Melke (from Lite 60 up to Centum), Alutech and SIAL aluminium systems. The company also runs an industry podcast with dealer interviews and talks with hardware makers.

Warranty and years in business

A separate page gives a twenty-year commitment on the profile itself. The home page names 2010 as the start of operations. Prices on 8 October 2026: a PVC unit from RUB 13,250 per m² without installation, a warm balcony with work included from RUB 34,675 per opening.

Nearby places
