Before appointing an interior company, ask for the warranty and after-sales process in writing. Confirm what work is covered, what is excluded, when coverage starts and ends, who receives a defect report, what evidence is needed, how the issue is assessed, what remedy may apply, and how supplier warranties are handled. Never rely on the word “warranty” alone.
Terms vary by provider, product, scope, and agreement. Do not assume any duration, remedy, response time, or coverage unless it is written. This is general information, not legal advice.
Warranty, After-Sales Service, and Supplier Support Are Different
These terms are often blended in sales conversations, but they answer different questions.
| Term | Practical meaning | What to request |
|---|---|---|
| Company warranty | A written promise connected to specified work or supplied items | Coverage, duration, exclusions, remedy, conditions, and responsible party |
| After-sales service | The process for questions, inspections, adjustments, complaints, and follow-up after handover | Contact route, reporting format, acknowledgement, assessment, status updates, and closure |
| Supplier or manufacturer warranty | Separate terms issued for a branded product, appliance, fitting, or hardware item | Card or document, invoice, model, serial number, registration needs, and claim route |
| Snag correction | Completion of an item recorded during handover | Numbered snag list, owner, action, target, evidence, and closure record |
| Paid maintenance | Service outside free correction or warranty scope | Visit fee, labour, materials, approval process, and quotation |
A handover snag, supplier product problem, and new cabinet request are different cases. Classify the request so the right party can respond.
Use the interior design handover checklist for Bangladesh to document the starting condition and any open snag items.
What Should a Written Interior Warranty Explain?
A warranty should be specific enough to apply consistently. Ask for plain answers before accepting the proposal.
Covered scope
Identify each covered room, component, material, or service. “Full interior warranty” is unclear without defined categories such as cabinetry, installation, specified hardware, finishes, countertops, glass, or service interfaces.
Identify who supplied and installed each component. Client products, developer work, building services, and another contractor’s work may have different responsibility.
Start point and duration
Ask what starts and ends the stated period. It might use handover, installation, invoice, or another defined milestone. Different components may have different periods.
There is no universal duration in this guide. Rely on the provider’s written offer and supplier terms.
Available response or remedy
Terms should state the response after confirming coverage, such as inspection, adjustment, repair, component replacement, or supplier referral. Do not assume a replacement or refund when the document promises something different.
Conditions and exclusions
Ask for exclusions beside the coverage. Distinguish workmanship concerns from wear, accidental damage, misuse, unsuitable cleaning, overloading, alteration, pests, external moisture, building movement, utility issues, or client-supplied item failure.
These are examples, not universal exclusions.
Build a Coverage Matrix Before You Sign
Turn sales language into a table and ask the provider to complete it.
| Item or work | Supplied by | Installed by | Company coverage | Supplier coverage | Exclusions or care conditions | Claim contact |
|---|---|---|---|---|---|---|
| Wardrobe carcass and fronts | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
| Hinges and drawer runners | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
| Countertop | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
| Decorative lighting | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
| Basin or sink fitting | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
| Paint or wall finish | To confirm | To confirm | To confirm in writing | If applicable | To confirm | Named contact |
This matrix reveals gaps when design, fabrication, services, and client purchases involve different parties.

What After-Sales Process Should You Ask For?
After-sales support needs a pathway, not only a phone number. ISO 10002 guides open and accessible complaints handling. Residential projects benefit from the same discipline.
Ask whether the provider’s process includes:
- One contact channel for service reports.
- Acknowledgement of receipt.
- A case or reference number.
- Classification as snag, warranty, supplier issue, maintenance, or new work.
- Evidence review and a site inspection when needed.
- A written decision linked to the terms.
- Approval before paid work or changed scope.
- Status updates through closure.
- A note recording what was done.
Ask the company to state acknowledgement, inspection, update, and resolution targets, including how access, parts, suppliers, or building permission may affect them.
How to Report a Possible Defect Clearly
Describe the symptom without guessing the cause. “Wardrobe door catches the lower panel” is more useful than “bad workmanship everywhere.”
Include:
- Name, project address, and contact details.
- Handover date and invoice, BOQ, or item reference.
- Room and exact location.
- Date you first noticed the issue.
- What happens under normal use.
- Wide and close photographs.
- A video when movement, sound, leakage, or intermittent operation matters.
- Any immediate safety concern or loss of essential use.
- Relevant care or usage history.
- The requested response, such as warranty assessment.
Keep originals and send copies through the agreed channel. Before dismantling or commissioning another repair, ask how it may affect assessment. For electrical danger, leakage, smoke, heat, or exposed wiring, stop unsafe use and contact a competent professional.
Understand Maintenance Obligations
A warranty does not remove the need for care. Ask about:
- Safe cleaners for laminate, veneer, paint, stone, glass, metal, and fabric.
- Prompt drying of water near board edges, joints, sinks, and vanity units.
- Ventilation and moisture management during humid or monsoon periods.
- Intended loads for shelves, rails, drawers, and wall-mounted units.
- Care of moving hardware and whom to contact for adjustment.
- Protection from weather, heat, and unsuitable chemicals.
- Access for plumbing, electrical, air-conditioning, and building services.
If verbal advice conflicts with a supplier manual, request written clarification. Use a competent person for technical maintenance.
Keep Supplier Warranties Separate and Usable
Hardware, appliances, lights, and fittings may have supplier terms. Company support and supplier warranty can overlap in communication but remain different documents.
Collect the warranty terms, purchase record, model, serial number, supplier contact, service route, and specified registration or installation evidence. Match identifiers to installed items.
Ask who contacts the supplier. The company may coordinate a claim or give documents to the homeowner. Record responsibility before appointment and at handover.
Questions to Ask Before Appointing an Interior Company
Use these questions with the broader questions to ask before hiring an interior design company.
- Can I read the full warranty terms before signing or paying an advance?
- Which design, fabrication, installation, and supplied product categories are covered?
- Which items are excluded, client-supplied, or covered only by a supplier?
- What event starts each coverage period, and what date ends it?
- What maintenance and care conditions must the household follow?
- Who receives a service report, and which channels create an official record?
- When should I expect acknowledgement, inspection, status updates, and a decision?
- Is there a visit charge or transport charge for a non-covered issue?
- How is paid maintenance quoted and approved?
- Who coordinates supplier warranty claims?
- What happens if the original product or finish is unavailable?
- How are recurring concerns escalated inside the company?
- Will I receive a written closure note after service?
- What documents, invoices, photos, or serial details should I retain?
- Can open snag items remain on a separate list instead of being mixed with later warranty cases?
Compare answers with the interior design timeline in Bangladesh. Reserve time for inspection and snag closure before after-sales support begins.
After-Sales Red Flags
Pause at undefined “lifetime service” or “complete warranty” claims. Other warnings include contradictory wording, no reporting channel or exclusions, missing supplier papers, no receipts, blank handover forms, or unapproved paid work.
Read the full guide to interior design company red flags in Bangladesh before choosing a team. A strong portfolio does not replace service clarity.
Records and Consumer Support in Bangladesh
Keep agreements, BOQs, drawings, variations, receipts, invoices, handover records, snag lists, terms, care instructions, photos, videos, and correspondence together.
For official complaint information, check Bangladesh’s National Consumer Rights Protection Directorate. Its procedure says complaints should be written and accompanied by the purchase receipt. It also publishes current hotline and online routes.
Legal questions depend on current law and individual facts. Consult the Directorate or a qualified adviser.
Frequently Asked Questions
Does every interior company in Bangladesh offer the same warranty?
No. Scope, duration, exclusions, process, and supplier coordination vary. Compare written terms, not headlines.
Is after-sales service the same as free repair?
No. It describes support. Whether service is free depends on the warranty, supplier terms, and confirmed cause.
Should a snag item become a warranty claim?
Not automatically. Keep a handover snag on its agreed list until closure instead of mixing it into a later service case.
What if the cause is unclear?
Report the symptom, limit damage where safe, and request assessment. Moisture, electrical, or structural concerns may need a relevant specialist.
