- Specify the main door as four parts: shutter, frame, hinges and lock; each can be the weak link.
- Shutter: 35–45 mm solid teak or engineered solid-core with veneer; seal all six faces.
- Engineered veneered doors cost ₹25,000–70,000; solid teak ₹40,000–1.5 lakh+ (Bengaluru, Oct 2026, before GST, frame extra).
- Use four ball-bearing hinges and a multi-point or mortise lock; digital locks need a mechanical override.
- In flats, a safety grille door adds airflow and security; check society rules.
The main door sets the first impression of a home and carries most of its security. It also faces the harshest conditions of any internal-facing door: corridor drafts, sun on villas, monsoon humidity and daily slamming. A main door that warps after one rainy season is a common complaint, and it almost always comes from the wrong material, an unsealed edge or a weak frame. This page is part of the doors guide.
Main door materials
| Construction | How it is made | Pros | Cons | Indicative ₹ (shutter) |
|---|---|---|---|---|
| Solid teak | Frame-and-panel or solid boards | Most durable, carvable, repairable | Expensive; quality varies by source and seasoning | ₹40,000–1.5L+ |
| Solid-core engineered with teak veneer | Timber or LVL core, hardwood lipping, veneer faces | Stable, flat, premium look | Veneer can be damaged by deep knocks | ₹25,000–70,000 |
| Solid-core flush with laminate | Block-board style core, laminate faces | Low maintenance, many designs | Plainer look | ₹12,000–30,000 |
| Steel-wood security door | Steel frame and skin, wood or laminate finish | High security, often fire-rated options | Heavy; fewer styles | ₹35,000–1.2L |
Indicative Bengaluru prices, October 2026, before GST, for a single main door shutter about 1050 × 2100 mm. Frame, hardware, polish and fitting are extra. Compare constructions in flush vs solid wood doors.
Size and proportion
- Flats: usually about 1000–1050 mm wide by 2100 mm high; a 2400 mm tall door looks noticeably more generous if the lintel allows.
- Villas and independent houses: 1200 mm single doors, or double doors 1500–1800 mm wide, often with a fixed side panel.
- Thickness: 35 mm minimum, 40–45 mm for tall or double doors.
Security: lock, hinges and frame
- Lock: a mortise lock with a deadbolt, or a multi-point lock that throws bolts at several heights. Digital locks should have a mechanical override and a multi-point body.
- Hinges: four heavy-duty stainless steel ball-bearing hinges for doors over about 40 kg; consider security (dog) bolts on the hinge side.
- Frame: seasoned hardwood or steel, anchored into the wall; a weak frame is the easiest point to force.
- Extras: a door viewer or video doorbell, a door closer, and a safety chain.
Weather and warping
Doors warp when one face absorbs moisture faster than the other. Seal all six faces (including the top and bottom edges) before hanging, leave even gaps of 2–3 mm, and protect exposed doors with a canopy or recess. For villa entrances facing west or south, choose engineered or steel-wood construction, or a teak door with a UV-resistant exterior finish, and re-coat it every few years.
Style options
- Modern: flush veneer with vertical grooves, a full-height pull handle, concealed hinges.
- Contemporary Indian: teak with brass inlay lines or a carved central panel.
- Traditional: carved teak with brass studs, sometimes with a kalash or floral motif.
- Double doors: for villas and wide openings; consider one fixed leaf with bolts.
Safety doors for apartments
A second door outside the main door, either a powder-coated steel grille or a mesh door, lets air in while the main door is open and adds a layer of security. Choose one with a proper lock rather than a padlock, and confirm the society allows it in the corridor.
Vastu and tradition
Many families consider the direction and design of the main door important in vastu; traditional guidance is covered in main door vastu. Practical points overlap: a well-lit entrance, a door that opens fully without obstruction and a clean threshold.
Worked example: a 3 BHK apartment main door in Bengaluru
| Part | Specification | Indicative cost |
|---|---|---|
| Shutter | 40 mm engineered solid-core, teak veneer, vertical grooves, PU finish all faces, 1050 × 2100 mm | ₹35,000–55,000 |
| Frame | Seasoned sal or teak, 125 × 65 mm, anchored | ₹9,000–18,000 |
| Hinges | 4 × stainless steel ball-bearing, heavy | ₹2,000–4,000 |
| Lock | Digital lock with mechanical override and multi-point mortise body | ₹15,000–35,000 |
| Handle and extras | Pull handle, closer, video doorbell | ₹6,000–18,000 |
| Fitting | Hanging, alignment, lock fitting | ₹2,500–5,000 |
| Total | Before GST | ₹69,500–1.35 lakh |
Indicative Bengaluru prices, October 2026. A laminated flush shutter with a good mechanical mortise lock brings the total to roughly ₹30,000–55,000.
Digital locks: what to check
- Mechanical override: a physical key for flat batteries or electronic faults.
- Lock body: a mortise or multi-point body, not just an electronic latch.
- Door thickness range: confirm it fits your shutter (often 40–80 mm).
- Access methods: PIN, fingerprint, card, app; choose what the family will actually use.
- Emergency power: an external terminal (often USB-C or 9 V) to power the lock if batteries die.
- Privacy and data: for app-connected locks, check where access logs are stored.
- Installation: by the brand's trained installer; poor cutting weakens the door.
Main door finishes compared
| Finish | Look | Durability | Upkeep |
|---|---|---|---|
| PU on teak or veneer | Rich grain, matt to gloss | Good; UV-resistant grades for sun | Re-coat outer face every 3–5 years if exposed |
| Melamine polish | Classic wood | Moderate; yellows in sun | Re-polish more often |
| Laminate | Wood, solid colours, textures | Very good | Wipe clean |
| Oil finish | Natural, matt | Moderate | Re-oil yearly |
| Paint / duco | Solid colour, modern | Good indoors | Touch up chips |
Design details that make a difference
- Full-height pull handle (1200–1800 mm) in brass, bronze or black: a strong modern statement.
- Matching cladding: extending the door veneer onto the wall around it makes a flat entrance feel grand.
- Name plate and lighting: a warm wall light or downlight at the entrance for safety and welcome.
- Threshold: a granite or marble sill protects the floor and marks the entrance.
- Toran and rangoli space: leave a clear wall above and floor in front for festive decoration.
Common mistakes
- Thin (30–32 mm) shutters on heavy main doors; they warp and the lock loosens.
- Unsealed top and bottom edges: moisture enters where nobody sees.
- A good lock in a weak frame.
- Digital locks with no mechanical override.
- Ignoring society or fire rules for the corridor face.
Before you decide
- What is the clear opening, and can it be made taller?
- Does the door face weather (villa) or a corridor (flat)?
- Do building or fire rules apply to the corridor face?
- Which lock will the family actually use daily, and is there a mechanical backup?
- Are frame, hinges, lock and finish all written into one quote?
Plan the main door with the foyer behind it: a shoe cabinet, a bench and a mirror make the entrance work from the inside. See shoe rack design.

Frequently asked questions
Which way should a main door open?
Most flats have main doors opening inward, which keeps the corridor clear and puts the hinges inside, out of reach. Check the building's fire and corridor rules before changing the swing.
Can a main door be double in an apartment?
Yes, if the opening is wide enough, often 1500 mm or more. A common solution is one wide active leaf and one narrow fixed leaf with flush bolts, which looks grand but opens like a single door.
How thick should a main door be?
At least 35 mm; 40–45 mm for tall, heavy or double doors. Thicker shutters stay straighter, hold locks better and insulate sound.
Is a fire-rated main door needed in an apartment?
Many high-rise buildings specify fire-rated entrance doors under fire safety rules. Check your building's approved plans and the association before replacing the door.
Teak or engineered wood for a main door in Bengaluru?
Both work in Bengaluru's mild climate. Engineered solid-core with teak veneer is more stable and cheaper; solid teak is more prestigious and repairable. For villa doors facing strong sun or rain, engineered or steel-wood doors with a good exterior finish hold up best.
Which wood is best for a main door?
Teak is the benchmark: stable, durable and naturally resistant to termites and weather. Sal is a strong, cheaper alternative for frames. Engineered solid-core doors with teak veneer give a similar look with better stability and lower cost, and are common in apartments.
What is the ideal size of a main door in a flat?
Typically about 1000–1050 mm wide and 2100 mm high (around 3′6″ × 7′), with a shutter 35–40 mm thick. Many builders fix the opening, so measure it; a taller door (2400 mm) looks grander where the ceiling allows.
Are digital door locks safe?
Good digital locks are as secure as quality mechanical locks when installed properly, and add features such as PIN codes, fingerprints and access logs. Choose one with a mechanical key override, a low-battery warning and a multi-point mortise body, and keep the batteries changed.
Do I need a safety door in an apartment?
A grille safety door or steel-wood security door adds ventilation and security, and many families like to open the main door without opening the home. Check society rules on what can be fitted in the common corridor.
How do I maintain a wooden main door?
Polish or PU-coat all six faces, including the top and bottom edges, before fitting. Re-coat the outer face every 2–4 years if it faces sun or rain, keep a canopy or recess over exposed doors, and oil hinges and locks yearly.
