You do not need to be an engineer to keep an eye on the quality of your home. Knowing what good work looks like at each stage helps you ask the right questions, spot problems early and work confidently with your builder. Most defects that trouble homeowners for years, such as leaks, cracks and damp walls, start with small mistakes during construction. This guide walks you through the key quality checks at every stage.
Before work begins
- Confirm the approved drawings are on site and match the sanctioned plan.
- Check that the site is marked correctly with the setbacks and orientation shown in the plan.
- Verify that materials on site match the agreed brands and grades. Our materials guide explains what to look for.
Stage 1: excavation and foundation
- Depth and size: Footings should be excavated to the depth and size shown in the structural drawings, and the bottom should reach firm strata as per the soil report. See our soil testing guide.
- PCC bed: A levelled plain cement concrete bed should be laid before placing reinforcement.
- Reinforcement: Bar size, spacing and cover blocks should match the drawings. Bars should not touch the soil.
- Anti-termite treatment: Should be done at the right stage, before the foundation and plinth filling.
Stage 2: plinth and columns
- Plinth beam level: Should be level and at the height shown in the drawings.
- Column alignment: Columns should be vertical and in a straight line. A plumb bob check is simple and effective.
- Column reinforcement: Check bar count, ties at the specified spacing and lap lengths.
- Plinth filling: Should be compacted in layers.
Stage 3: RCC beams and slabs
This is the most critical stage for the structure.
- Shuttering: Should be strong, level and leak-proof, with proper props.
- Reinforcement: Check bar sizes, spacing, cover blocks and extra bars at supports.
- Electrical conduits: Should be placed before concreting, as per the electrical layout.
- Concrete grade: Should match the specified grade, usually M20 or M25 for homes.
- Cube tests: Concrete samples should be taken for cube testing to confirm strength.
- Curing: Slabs must be kept wet for the specified period.
Our guide to RCC slab casting and curing covers this stage in detail.
Stage 4: masonry
- Blocks or bricks: Should be of the agreed type and quality. See AAC blocks vs red bricks vs concrete blocks.
- Mortar: Joints should be uniform and fully filled.
- Alignment: Walls should be straight and plumb.
- Lintels: Should be provided over all doors and windows.
- Curing: Masonry should be cured properly.
Stage 5: plumbing and electrical rough-in
- Plumbing pipes should be pressure-tested before they are concealed.
- Bathroom floors should have proper slopes towards the drains.
- Electrical conduits and boxes should match the layout, with separate circuits for heavy loads such as air conditioners and geysers.
- Wire gauges should match the specification. See our electrical and plumbing materials guide.
Stage 6: waterproofing
- Bathrooms, balconies, terraces and sunken areas should be waterproofed with the specified system.
- A pond test, keeping water on the treated surface for 24 to 48 hours, confirms there are no leaks before tiling.
Read our waterproofing guide for more.
Stage 7: plastering
- Plaster should be even, without hollow sounds when tapped.
- Corners and edges should be straight.
- Curing should be done for the recommended period to prevent cracks.
Stage 8: flooring and tiling
- Tiles should be level, with uniform joints and no hollow sounds.
- Bathroom and balcony floors should slope towards the drains.
- Skirting should be neatly finished.
Stage 9: doors, windows, paint and fittings
- Doors and windows should open and close smoothly, with proper locks and seals.
- Paint should be even, without patches or drips.
- Electrical switches, sockets and fittings should work correctly, with proper earthing.
- Sanitaryware should be fixed firmly without leaks.
Simple tools that help on site visits
You can check a surprising amount with a few inexpensive tools. A measuring tape confirms room sizes, door widths and setbacks against the drawings. A spirit level shows whether floors, platforms and window sills are level. A plumb bob, or a smartphone level app, shows whether walls and columns are vertical. A torch helps you look into ducts and under sinks for leaks. A coin or the handle of a screwdriver lets you tap tiles and plaster to listen for hollow sounds. Take photos and short videos on every visit, with the date, so you have a record of each stage.
How often should you visit?
Weekly visits are ideal during the structural stage, especially on slab days, and every one or two weeks during finishing. Try to be on site for key milestones: foundation reinforcement, each slab pour, waterproofing pond tests and the final walkthrough. If you cannot visit often, ask your builder for photo updates and a short call with the site engineer after each milestone. Good builders welcome informed owners, because they catch issues early and avoid disputes later.
Questions to ask your site engineer
- Has this stage been checked against the drawings?
- What are the cube test results for the last slab?
- How long will this element be cured?
- Has the plumbing been pressure-tested?
- When is the waterproofing pond test scheduled?
Snag list before handover
Walk through the home with your builder and note every defect: chipped tiles, paint touch-ups, leaking taps, loose fittings. A professional builder fixes these before handover. Make sure your warranty documents are in hand. See our warranty details.

Frequently asked questions
How can I check construction quality without technical knowledge?
Use a stage-by-stage checklist, compare materials with the agreed brands, ask for cube test results, watch curing and check alignment and levels with simple tools like a plumb bob and spirit level.
What is a cube test in construction?
Concrete samples are cast into cubes and tested for compressive strength after 7 and 28 days to confirm the concrete meets the specified grade.
When should I do a final inspection?
Before handover. Walk through every room with your builder, prepare a snag list and make sure all items are fixed before final payment.
