Carpentry & Joinery – Projects and Qualified Teams

Carpentry and joinery covers all high-quality timber work in interior fit-out: interior doors with frames, fitted furniture (kitchens, wardrobes, cloakrooms), wooden stairs, solid wood floors, wooden acoustic ceilings, wall panelling, casings, and bespoke furniture to measure. Unlike framing carpentry (load-bearing, roof structures), the joiner works to millimetre precision on visible interior fit-out. Materials range from solid wood (oak, ash, walnut) through veneers to premium board materials (multiplex, MDF, coated chipboard). CNC prefabrication with on-site installation is now standard. Example Germany: VOB/C DIN 18334 'Carpentry and timber work' and DIN 18355 'Joinery' apply, plus fire and acoustic requirements per component.

How long does fitted kitchen installation take?

How much does carpentry cost as subcontracted work?: Example Germany: interior door with frame installed 350–800 € (standard) up to 1,500 € (premium). Fitted wardrobe 600–1,500 €/lm of front. Custom wooden stairs 4,000–12,000 €. Acoustic ceiling 80–250 €/m². Joiner hourly rate 45–75 €/h. In Poland 30–40 % below.
Which door classes are distinguished?: Example Germany: apartment entrance doors with acoustic rating Rw ≥ 32 dB, fire-rated T30/T60/T90 (DIN 4102), smoke-control RS, security RC1–RC4. Public buildings often require combinations (T30-RS-acoustic). Standard height 198.5/211 cm, width 73.5–98.5 cm.
Which wood species and board materials are standard?: Oak and beech in residential, ash and maple in modern interiors, walnut and cherry in premium furniture, larch outdoors. Boards: laminated chipboard (standard), MDF (paintable and veneerable), multiplex (very stable), thin plywood (light, formable).
Which fire and acoustic requirements apply?: Example Germany: apartment entrance doors per DIN 4109 (min. Rw ≥ 27 dB, typically 32 dB). T30 doors in apartment-block stairwells mandatory. Solid wood floors must meet fire class (Cfl-s1 per DIN EN 13501-1). Acoustic ceilings have defined α values.
What are the most common defects?: Warping of wood components from poor storage or climate, sticking doors from uneven masonry and poor adjustment, visible gaps from solid wood shrinkage, poor lacquer finish from high humidity, dimensional errors from prefabrication without precise survey.
How long does fitted kitchen installation take?: Standard L or U-shape with 6–8 lm of cabinets and appliances: 2–3 days for two-person team incl. water/power connections (by trade specialist). Solid wood or bespoke: 4–6 days. Survey and prefab 4–8 weeks before installation.
