Finishing to Handover in House Construction 2026 | Painting, Fixtures & Final Tips
The sun was gently setting over the construction site. Contractor Kaka was sitting on his old plastic chair, sipping tea with a cigarette in his hand. Engineer Babu walked in smiling, carrying samples of finishing materials.
Kaka: (blowing out smoke with a big smile) Hey Babu, now it’s time for the “makeup” of the house! The structure is strong, but now we have to make it look beautiful. The clients have already started saying, “Kaka, please do the painting and tiles properly. We want to take nice photos!”
Babu: (smiling) Exactly, Kaka. This is the final part – House Construction Process 2026, Part 4, covering Finishing to Handover. I’ll explain the planning and technical aspects, and you can share the practical on-site tips, common mistakes, and how to avoid them.
Kaka: Perfect, Babu. I’ve been doing this for 26 years. Making the structure strong is not enough. If you become careless during finishing, you’ll end up doing repairs again and again. Come on, let’s complete the last four steps today.
In this part, we cover the final four steps out of the total 16 steps:
- Step 13: Painting & Exterior Finishing
- Step 14: Doors, Windows, Woodwork & Railing
- Step 15: Final Electrical, Plumbing Fixtures & Testing
- Step 16: Cleaning, Final Quality Check & Handover
Step 13: Painting & Exterior Finishing – Finishing to Handover
Babu: Kaka, many people think painting is just decoration, but it actually acts like the “skin” of the house. It protects the RCC structure and bricks from moisture. According to NBC 2025 (Nepal Building Code), exterior walls must use high-quality weather-resistant and anti-fungal paint to prevent flaking and fading.
Technical Aspects on Finishing to Handover:
- Surface Preparation: Fill all hairline cracks with wall putty before painting.
- Importance of Primer: Never apply paint directly. Always use 1 coat of primer followed by 2 coats of paint.
- Paint Selection:
- Interior: Premium washable emulsion (e.g., Royale, Velvet)
- Exterior: Dust-proof and weatherproof paint (Asian Paints Apex Ultima, Dulux Weathershield, or Berger Weathercoat)
- Area Calculation: For a 1500 sq.ft house, you may need to paint 3500–4200 sq.ft (walls + ceiling, minus doors and windows).
💡 Pro Tip: Use our House Paint Calculator 2026 on Nirman Sutra Tools to know exactly how many liters of paint you need and how much it will cost.
Kaka: (smiling while taking a puff) Babu, you gave the bookish knowledge, now let me share real experience. Many people are in a hurry. They start painting while the plaster is still damp. The cement inside is still reacting, which causes bubbles and peeling later.
Kaka’s Practical Tips on Finishing to Handover:
- Wait at least 21 to 28 days after plastering before painting. The wall must be completely dry.
- Moisture Test: Stick clear plastic on the wall with tape for 24 hours. If you see water droplets inside, the wall is still wet.
- Choose light colors for Kathmandu — dark colors get dirty quickly due to dust.
- Apply extra waterproof coating on the terrace, parapet walls, and window sills.
- Tell the painters: “Don’t make the paint too thin by adding extra water. Use the roller properly so there are no streaks.”
Step 15: Final Electrical, Plumbing Fixtures & Testing
Babu: Kaka, after all the rough-in work (concealed pipes and wiring) is done, it’s time for final fixtures. We install switches, lights, taps, and showers. But installation alone is not enough — proper testing as per NBC and electrical safety standards is mandatory.
Technical Checklist on Finishing to Handover:
- Electrical: Use modular switches (Legrand, Anchor, GM, or Goldmedal).
- Lighting: Energy-saving LED panels and decorative lights.
- Plumbing Fixtures: Choose durable brands like Jaquar, Cera, Kohler, or Grohe.
- Earthing Resistance: Must be below 1 Ohm for safety.
- Pressure Test: Test plumbing pipes at 1.5 times normal pressure to check for leaks.
💡 Tip: Use our Electrical & Plumbing Cost Estimator on NirmanSutra Tools for accurate budgeting.
Kaka: (seriously) Babu, I personally sit with the workers during this stage. Once, fixtures were installed in a hurry and later a concealed pipe started leaking, damaging expensive tiles. We had to break everything again. So I follow strict rules:
Kaka’s Pro Rules on Finishing to Handover:
- Never install tiles before doing a hydraulic pressure test on all concealed pipes.
- Complete earthing test before installing switches and expensive devices.
- Run water for 24 hours after installing all taps, showers, and toilets to check joints.
- Do inverter and solar wiring at the very end.
- Use separate heavy-duty wires and MCBs for AC and geyser points.
Step 16: Final Cleaning, Quality Check & Handover
Kaka: (happily wiping sweat from his forehead) Babu, after many months of hard work, the house is finally standing tall. Now only the last job remains — cleaning every corner and handing over the keys to the client.
Babu: Yes, Kaka. Before handing over, we must complete the Technical Handover process. The owner should not only get the house but also all technical documents for future maintenance.
Technical Checklist for Finishing to Handover:
- As-Built Drawing (actual wiring and plumbing layout)
- Structural Stability Certificate
- Electrical and Plumbing Test Reports
- Warranty cards of all materials
- Final cost summary
Kaka’s Practical Finishing to Handover Process:
- 3-Step Cleaning: First remove big debris, second acid clean tiles and glass, third fine dusting.
- Disinfect and clean the water tank properly.
- Do final touch-up painting where needed.
- Give full training to the owner — how to operate everything.
- Check all doors, windows, hinges, and locks.
Babu: Perfectly said, Kaka. When an engineer’s brain and a contractor’s hands work together, a simple structure turns into a safe and beautiful dream home.
Conclusion
