Installation of doors and portals


Stable door and portal installation: accurate opening geometry, even gaps and smooth hardware.

Urgent:8(800)550-2336

WarrantyTerms and coverage are set out in the contract: up to 25 years on in-house manufactured items and up to 2 years on installation — subject to proper operating conditions.


Principle 1: Substrate and datum "zero"

Every installation starts with assessing substrate density and flatness and establishing datum zero. Without this, stable junctions and correct node behavior are impossible.

Principle 2: Moisture under control

We control substrate and material moisture before work begins. This reduces the risk of deformation, squeaks and joint opening after handover.

Principle 3: Specification for the project

We choose installation technology by project type and loads: operation sequence, adhesive type, layering, moisture barrier and finish protection.

Principle 4: Handover with a care regime

After installation we check geometry and junctions, provide operating guidelines and perform service adjustments when needed.


Installation of doors and portals

Preparation and climate

Before work we check humidity and temperature, finish floor condition and substrate stability. Balanced climate for wood reduces seasonal size change and twist risk.

Opening geometry

We check plumb, level and diagonals, measure width and height at several points, relate to finished floor level. Deviations are resolved with a technical compensation plan.

Frame and portal

We set the frame in the design plane with rigid fixing of key points, then assemble portal and architraves with a consistent profile rhythm. Junctions to wall, skirting and floor stay visually continuous.

Leaf and hardware

We hang the leaf, fit locks, hinges, closers and magnetic latches with staged adjustment. Even working gaps, correct rebate and predictable movement without sticking.

Post-installation check

We test opening and closing, locks and handles, architrave fit and perimeter joints. We hand over care notes and seasonal service adjustment guidance.


  • Unified frame and portal geometry by level and diagonals.
  • Even working gaps around the leaf.
  • Correct lock, latch, closer and hinge action without force.
  • Stable junctions to floor, wall and skirting without visible steps.
  • Operating regime and service adjustment after handover.

WarrantyTerms and coverage are set out in the contract: up to 25 years on in-house manufactured items and up to 2 years on installation — subject to proper operating conditions.

Installation FAQ

Subfloor, moisture, method, supervision

What is included in turnkey parquet installation?

Subfloor prep (≤2 mm / 2 m), acclimation, laying by method sheet, sanding, oil or lacquer, skirtings. Indoor humidity 40–60%. Moscow region and Russia-wide.

Do you install third-party products?

Priority is Cardinal Hall manufacture for geometry and joints. Third-party after compatibility audit.

Which parquet laying methods do you use?

Traditional (plywood + PU), modern (silane, no plywood), historic (joists) and artistic (modules/pattern) — locked in the project method sheet.

Do one crew install kitchens, doors, stairs and panels?

Yes — one crew covers parquet, kitchens, doors, stairs and boiserie with shared junctions and contract deadlines.

Where do I book survey and installation?

Showroom Casa Ricca Expo, Rublyovskoye sh. 52A, pavilion 323, Moscow. Quote: contacts#quote. Install across Russia and abroad by schedule.

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

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

How long does Cardinal Hall dry timber?

280 days of chamber and thermobaric drying. 6–8% moisture, ±0.5 mm geometry.

What warranty does Cardinal Hall offer?

25 years on products, 2 years on installation.
