Rs. 12-28 per sq.ft

House painting cost in Chennai commonly ranges from about Rs. 12 to Rs. 28 per sq.ft under Seal & Cool's indicative service pricing, depending on wall condition and paint quality. The figure can include very different levels of scraping, putty, primer, coats, protection, and cleanup, so a useful quote must describe the complete paint system.

What is included in a professional painting estimate

The estimate should identify measured area, surface condition, preparation, putty requirement, primer, paint brand and product line, number of coats, colour changes, masking, access, and cleanup.

A repaint over a sound similar colour needs less work than a wall with dampness, peeling layers, cracks, or a major colour change. These conditions should be inspected before a fixed price is offered.

  • Measurement and wall-condition assessment
  • Scraping, sanding, crack filling, and putty
  • Primer and specified finish coats
  • Masking, furniture protection, access, and cleanup

Interior versus exterior painting costs

Interior painting focuses on finish, washability, occupied-room protection, and controlled drying. Exterior work needs weather-resistant preparation, access equipment, crack treatment, and a system suitable for sunlight and Chennai monsoon exposure.

Exterior elevations may cost more when scaffolding, height safety, difficult access, or extensive plaster repair is required. Ask contractors to separate these items from the paint rate.

  • Interior: protection, smoothness, colour, and washability
  • Exterior: access, cracks, weather resistance, and safety
  • Ceilings, doors, grills, and woodwork priced separately
  • Damp-wall treatment assessed before repainting

Why surface preparation controls paint life

New paint bonds to the layer beneath it. If loose paint, chalking, dust, dampness, or weak putty remains, the finish can peel even when the topcoat is premium.

Water entry should be repaired before painting. Anti-damp products may support a suitable system, but they cannot replace correction of an active terrace, plumbing, bathroom, or exterior leak.

  • Remove loose and incompatible layers
  • Repair the source of dampness first
  • Allow repaired surfaces to dry
  • Use compatible filler, putty, primer, and topcoat

How to compare house painting quotations

Compare the same measured area and product specification. One quote may include wall putty and primer while another includes only two finish coats, making the total prices misleading.

Confirm paint ownership, colour approval, furniture movement, daily cleanup, touch-up policy, timeline, and final inspection. These details affect both cost and the experience of painting an occupied home.

  • Match area, preparation, and coat count
  • Confirm exact product line, not only brand
  • List exclusions such as repairs, height access, and woodwork
  • Agree on colour samples, cleanup, and final touch-ups

Need this handled on site?

We inspect the problem before quoting. That keeps the repair scope, materials, and timing aligned with the actual condition of the slab or roof.

Frequently Asked Questions

What is the house painting cost per sq ft in Chennai?

Seal & Cool's indicative range is about Rs. 12 to Rs. 28 per sq.ft depending on wall condition, preparation, putty, primer, paint quality, and coat count.

Does painting cost include putty and primer?

Not always. Ask for scraping, crack filling, putty, primer, finish coats, labour, protection, and cleanup to be stated separately or clearly included.

Can damp walls be painted directly?

No. The moisture source should be diagnosed and repaired, and the wall allowed to dry before a compatible paint system is applied.

How many coats are needed for house painting?

The requirement depends on substrate, old colour, new colour, primer, product coverage, and finish expectations. The contractor should specify the system after inspection.
