Steel or Wood?
See the real 10-year cost.

Wood looks cheaper on day one. In a salt-air coastal climate, that changes fast. Move the slider and see how the two totals actually compare.

Choosing between a steel door and a wood door is one of the most common decisions homeowners in Kanyakumari and Tirunelveli face when building or renovating. Wood has always felt like the traditional, familiar choice — but the coastal humidity and termite pressure in this region change the maths considerably once you look past the upfront price tag.

This page breaks down the real cost difference over time, not just the sticker price, so you can compare steel and wood doors the way they actually perform in a coastal home.

Common questions

Is a steel door cheaper than a wood door in the long run?

In most coastal homes, yes. Wood usually costs less upfront, but recurring polish, termite treatment and humidity repair mean steel typically becomes the cheaper option within 8 to 10 years.

Do steel doors rust in coastal areas like Kanyakumari?

Powder-coated steel doors are treated specifically for salt-air exposure and resist rusting far better than untreated metal. Periodic repainting every few years maintains this protection.

How often does a wood door need termite treatment?

In humid coastal regions, wood doors typically need termite treatment every 2 to 3 years, along with periodic polishing and occasional repair for moisture-related warping.

What is the average cost of a steel door in Kanyakumari and Tirunelveli?

Mid-range steel doors typically start around ₹18,000 per door installed, varying by size and design. RIDGE offers exact quotes based on door dimensions and site requirements.
