How to Choose a House Construction Company in Bangalore: 10 Things to Check Before You Sign

Every construction company in Bengaluru will tell you they use quality materials, deliver on time and treat your home like their own. The brochures are close to identical. So are the websites.

The differences only appear in the answers to specific questions, and most homeowners never ask them, because they do not know which questions matter. Here are ten that do.

Take this list to your next three meetings. The answers will separate the firms faster than any amount of brochure reading.

1. Are the people on my site your employees, or subcontracted?

This is the first question and the most revealing, because it decides who is accountable when something goes wrong.

A company with its own masons, engineers and site managers carries one team through your project from foundation to handover. The person who cast your columns is still around when the plastering starts. Mistakes get owned because there is nobody else to hand them to.

A company that subcontracts each stage passes your house between crews every few months. The tiling contractor blames the plastering contractor, who has already been paid and left. You end up mediating between people you never hired.

Both models exist. The second is far more common and considerably cheaper to run. Just know which one you are buying.

Ask them: “If I visit in month four and again in month eight, will I see the same site engineer?”

2. What concrete grade are you using, and where?

A straightforward technical question with a revealing answer.

A good builder will tell you immediately: plain cement concrete for the bed, M20 or M25 for reinforced work, and it is specified element by element in the structural drawing. They will show you the drawing.

A weaker one will say “best quality” or “standard grade”. Those are not grades. If the person quoting for your house cannot name the concrete grade, they are not the person who will be checking it on site either.

Ask them: “Can I see the structural drawing with the grades marked?”

3. Where are the cap prices?

This is the single most useful thing you can look for in a quotation, and most quotations do not have it.

“Premium vitrified tiles” means nothing. It could be ₹45 per square foot or ₹130. Same phrase, entirely different floor.

A quotation with cap prices states a maximum rate against each item: flooring capped per square foot, sanitaryware capped per toilet, kitchen countertop capped per square foot, main door capped per shutter. You know precisely what standard you are buying, and if you want better, you know exactly what the upgrade costs.

Without caps, the specification is whatever the builder decides it is on the day, and you will not find out until the material arrives.

Ask them: “Can you give me the quotation with a maximum cap price against every finish item?”

4. What is excluded?

Every builder writes an appealing inclusions list. The exclusions are where the arguments start.

Commonly excluded and commonly forgotten: soil filling and compaction, borewell, sump beyond a stated capacity, compound wall, gates, landscaping, electricity and water connection deposits, and approval fees.

None of these are unreasonable to exclude. All of them cost money. If they are not written down, you will be having that conversation at the worst possible moment, halfway through a build, with no leverage.

Ask them: “Please send me the exclusions list in writing before I sign.”

5. What happens if material prices rise?

Steel and cement move. A contract that pretends otherwise is either priced with a large cushion, or it is going to produce an awkward conversation in month six.

The professional answer is a written escalation clause: what triggers it, how it is calculated, and what cap applies. The unprofessional answer is a shrug and “we will adjust if needed”, which means they will adjust, and you will have no basis to argue.

A fixed-price contract with a clearly defined scope is better still. But the scope has to be genuinely defined, which brings you back to cap prices.

Ask them: “Is this a fixed price? If material costs rise 15%, what happens to my quote?”

6. Can I see a concrete cube test report?

Concrete samples are cast on the day of a pour and crushed in a lab at 7 and 28 days to confirm the mix reached its designed strength. It is standard practice on well-run sites and skipped on many residential projects.

A builder who tests routinely will produce a report without hesitation, probably from a project running right now. One who does not will explain why it is unnecessary for houses.

It is not unnecessary. It is the only objective evidence that the concrete holding up your home is what you paid for.

Ask them: “Do you cube-test every pour, and will those reports be handed to me at the end?”

7. Can I visit a site you’re building right now?

Not a finished house. Finished houses all look good, which is why they are the only ones you get shown.

A live site tells you everything a showcase cannot. Is reinforcement covered and off the ground, or rusting in a corner? Are materials stacked properly or scattered? Is the site tidy when work stops for the day? Is anyone visibly supervising? Are workers wearing any safety equipment at all?

Twenty minutes on an active site is worth more than an hour of presentations. A builder confident in their work will offer this before you ask.

Ask them: “Which of your current sites can I walk around this week?”

8. How is the payment schedule structured?

Payments should be tied to completed stages of work, verified before release. Foundation complete, ground floor slab cast, first floor slab cast, blockwork complete, and so on.

Payments tied to calendar dates remove your only meaningful leverage. If money arrives whether or not work has progressed, there is no commercial reason to keep to the programme.

Also check the advance. A modest booking advance is normal. A demand for a large share of the contract value before anything happens on site is a warning worth taking seriously.

Ask them: “Is every payment linked to a stage I can physically inspect before I release it?”

9. Who handles the BBMP approvals?

Plan sanction requires A-Khata and, since July 2025, an e-Khata as well. Applications need AutoCAD drawings signed by a COA-registered architect, and with complete documents the process typically takes 30 to 45 working days. Our step-by-step guide to building a house in Bangalore covers the full approval sequence.

Turnkey firms usually handle this. Labour contractors usually do not. The gap between those two assumptions is where projects lose two months, because each side believed the other was dealing with it.

Settle it in writing, along with who pays the fees.

Ask them: “Is plan sanction inside your scope, and are the approval fees inside your quote?”

10. Can I speak to a client whose project didn’t go smoothly?

Any builder can give you three delighted customers. That tells you they have completed at least three good projects.

Ask instead for someone whose project hit a problem. Every builder has one — a design change midway, a site issue, a delay. What matters is what happened next.

A confident firm will give you that number, because the recovery is a better story than an untroubled build. A firm that cannot produce a single client who had an issue is either very new or not being straight with you.

Ask them: “Is there a client whose project ran into difficulty who’d be willing to speak to me?”

The answers, side by side

If you only remember six of the ten, remember these.

Two more things worth checking

How long have they actually been building?

Years in business and number of projects completed are easy to verify and hard to fake at scale. Ask for the number, then ask to see two or three from the earliest years. Houses built eight years ago reveal considerably more about construction quality than houses handed over last month. Walking through a firm’s completed projects is a fair place to start.

What happens after handover?

Ask about the defects liability period, how long it runs, what it covers, and who you call. A builder who disappears at handover was never selling you a home, only a transaction.

Frequently asked questions

How do I verify a construction company in Bangalore is genuine?

Check GST and company registration, ask for completed project addresses you can visit, speak to at least two past clients directly, and visit a site currently under construction. Documents are easy to produce; a live site is not.

Should I choose the lowest quote?

Rarely. The lowest quote is usually the least specified, and the difference tends to reappear later as escalations, when you have no leverage. Compare specifications item by item before comparing totals.

What is the difference between a labour contractor and a turnkey construction company?

A labour contractor supplies labour while you buy materials and manage the project. A turnkey company handles design, approvals, materials, execution and handover against an agreed specification, so accountability sits with one party.

How much advance should I pay?

A modest booking advance is standard practice. Everything after that should be linked to verified stages of completed work rather than dates.

What should a construction quotation include?

Cap prices against every finish item, named brands and grades for structural materials, a written exclusions list, a stage-linked payment schedule, and a clear position on price escalation.
