Why 280 days of wood drying instead of the standard 30-60 days?

280 days of chamber drying isn't marketing—it's a technological necessity. In the first stage, timber sawn into 'frize' strips and air-stacked in piles with spacers is conditioned in ventilated workshops. That way we reduce moisture by 25–30% from the initial value as gently as possible. The second stage takes place in a vacuum-convective chamber with thermo-humidity treatment developed by our in-house engineering team. It is essentially the same natural process, scaled to an industrial workflow. Frize strips on trolleys with spacers enter the drying chamber. Hot air is the drying medium. Wood temperature is raised to +55 °C, then vacuum is applied with internal pressure reduced to 0.8 atm. Together, these conditions bring sap to a boil for 10–15 minutes per cycle. The cycle runs 48 times per day and continues until the wood reaches 9±1% moisture.

How do you work with clients and confidentiality?

100% of projects under NDA—this isn't optional, it's standard. We don't publish addresses, client names, or floor plan details without written permission. Photography only with client consent, often prohibited entirely. Our team signs personal non-disclosure agreements. For clients from public spheres (politics, business, culture), we can operate through structured legal entities without revealing the ultimate beneficiary. Payment possible via escrow accounts with bank guarantees from top-10 institutions.

Is the 25-year warranty real or just marketing?

Real, but conditional. The warranty covers structural integrity when the temperature-humidity regime (18-24°C, 40-60% humidity) and operating conditions are met.

What's the point of a comprehensive solution: floor + walls + furniture from the same wood?

First, aesthetics: unified grain pattern, tone, and transition from floor to panels, panels to kitchen facades creates a sense of cohesive space, as if the interior is 'carved' from a single block. Second, technology: using one timber batch, we guarantee identical reaction to humidity and temperature—floor and panels 'breathe' synchronously, no deformations at joints. Third, logistics: one supplier, one installation cycle, unified warranty. For clients: one call, design project with all technical nodes, one contract, one responsibility.

Can you restore 19th-century parquet in cultural heritage sites?

Yes, it's one of our core competencies. We've worked in the Kremlin (Red Square), Vaganova Ballet Academy, dozens of estates and mansions. Process: complete documentation (photos, measurements, species analysis, identification of historical installation techniques), then dismantling damaged areas while preserving 80-90% of the original, restoring lost planks by matching timber species, grain, and grade. Finishing layer restoration with application of protective coating (lacquer or oil) to extend service life.

Can you sand engineered board?

Yes — engineered board sanding works while the wear lamella remains. Below it is the stabilizing layer: sanding into it ruins the floor. We measure lamella thickness before work and state how many cycles remain.

How is engineered board restoration different from solid parquet sanding?

Same steps (diagnosis, sanding, filling, finish), but engineered board has less thickness reserve than solid. If the lamella is spent, we recommend replacement rather than forcing another pass.

When is parquet sanding enough vs full replacement?

Sanding works while the wear layer allows (usually 5–7 cycles on solid; fewer on engineered). If boards are destroyed or detached over ~30% of the area — replacement. Survey on request in Moscow and beyond.

What is included in turnkey parquet sanding?

Diagnosis, coating removal, leveling, filling, optional toning, Saicos/Osmo oil or Loba lacquer, polish and care guide — local or full floor, solid or engineered.

Do you restore solid furniture, kitchens and doors?

Yes — kitchen fronts, solid furniture, doors, stairs and panels: joints, missing parts, toning and finish matched to the interior.

Where can I request wood restoration?

Showroom Casa Ricca Expo, Rublyovskoye sh. 52A, pavilion 323, Moscow. Site visits in Moscow/region; larger projects across Russia. Quote: contacts#quote.

How is home restoration different from listed buildings?

Home work is sanding and wood repair without heritage status. Listed buildings are a separate page: archives, approvals, documentation.

What is Cardinal Hall's single-batch wood concept?

One wood lot for the entire interior — floor, doors, kitchen, stairs — identical tone for decades.
