FAQ

Questions B2B buyers usually ask first.

Baida Housing is not designed to compete for the lowest quotation. Many low-cost expandable houses reduce price by using thinner panels, basic flooring, simple windows, weak sealing, or lower-grade exterior materials. These choices may look acceptable before shipment, but they often create problems after installation. Baida focuses on upgraded materials, better door and window systems, stronger flooring options, improved wall panels, and more detailed project communication, so B2B buyers can reduce after-sales risk and protect their market reputation.

We focus on the problems buyers often report with low-cost expandable homes: thin wall panels, poor flooring feel, water leakage, moisture risk, mold concerns, weak door and window performance, and rust or aging of exterior parts. Baida improves these areas through material selection, R&D-led product upgrades, better sealing details, upgraded floor and wall options, and stricter configuration control before production.

Baida Housing offers upgraded door and window options for buyers who care about comfort, sealing, insulation, and long-term use. Depending on the project configuration, options include micro-ventilated casement windows, integrated window screen systems, heavy lifting sliding doors, triple insulating glass, thermal break profiles, EPDM sealing strips, and aluminum profiles. These details help improve air sealing, sound reduction, thermal performance, and daily usability.

Waterproofing is not solved by one material alone. It depends on the roof joints, folding connection areas, door and window sealing, bathroom waterproofing, drainage direction, wall system, foundation, and correct installation. Baida pays attention to sealing details, door and window systems, bathroom components, wall material selection, and installation communication before shipment. For humid, rainy, or coastal markets, we recommend confirming the climate, drainage conditions, and usage scenario before production.

Baida Housing offers standard PVC flooring and upgraded SPC stone plastic flooring options. For buyers targeting higher-end markets, SPC flooring can provide a more premium surface feel, better appearance, and improved long-term durability compared with basic flooring options. Flooring selection should be confirmed based on the target market, budget, usage intensity, and buyer expectations.

Baida Housing can provide different wall and interior panel options according to the project level, including bamboo and wood fiber panels, anti-collision integrated panels, WPC wall panels, metal carved panels, and other project-based material options. These choices help buyers balance appearance, insulation, moisture resistance, surface durability, and cost. We recommend choosing wall materials based on climate, target customer group, and expected service life, not only on the lowest price.

Yes. Baida Housing supports customization for layout, exterior materials, wall panels, flooring, doors, windows, bathroom, lighting, electrical configuration, and interior finish level. However, we do not recommend customization based only on appearance. Before production, we review the buyer’s market, climate, project use, quantity, shipping method, and installation plan, so the final configuration is practical for production, delivery, installation, and long-term use.

Baida Housing expandable houses can be configured for different climates, but the right configuration must be confirmed before production. For rainy or humid areas, buyers should pay attention to waterproofing, ventilation, wall materials, flooring, and drainage. For coastal areas, exterior material and anti-corrosion details are important. For cold markets, insulation, windows, flooring, and heating planning should be reviewed carefully. Baida can recommend suitable upgrades based on the destination market and application.

To provide an accurate quotation, please share the destination country or port, intended use, required size, layout, quantity, wall and insulation preference, flooring option, door and window requirements, bathroom and kitchen needs, electrical standard, plumbing and drainage requirements, interior finish level, trade term, and site installation conditions. A low quotation without clear specifications is risky because it may not include the materials and details your project actually needs.

Baida Housing can provide installation guidance, product specifications, configuration confirmation, project communication, and remote support according to the order scope. Local permits, zoning approval, utility connection approval, and occupancy requirements are controlled by local authorities and should be confirmed by the buyer, local contractor, architect, or engineer. For B2B buyers, we recommend confirming warranty scope, inspection process, spare parts, and installation responsibility before shipment.
