Frequently Asked Questions
Customer Questions We Hear Most Often
What kind of problems does FOUR WALLS solve?
We solve issues like roof and terrace leakage, basement seepage, wall dampness, tank leakage, bathroom / toilet seepage, structural cracks, and peeling paint. We also provide epoxy flooring, grouting and annual maintenance contracts for buildings.
How do I book a site visit or inspection?
You can Call / WhatsApp us at +91 9903915562 or fill the contact form on our website with your location and problem details. Our team will contact you to schedule a convenient time for inspection.
Is the site inspection free?
For nearby areas around Batanagar, Maheshtala and parts of Kolkata, basic inspection is usually free or adjusted in the work order. For far locations or detailed technical inspections, a small visit charge may apply – which we inform you clearly in advance.
How do you decide which waterproofing system to use?
We first inspect the site, understand the source of leakage and check the condition of the surface. Based on this, we choose from PU coatings, latex systems, membranes, grouting or cementitious products. We don’t believe in “one product for all” – we choose what suits your problem best.
Do you provide warranty on your work?
Yes. We provide job-specific warranty / guarantee depending on the type of work and materials used. Warranty details are clearly mentioned in our quotation and work order before starting the job.
Testimonial
We offer expert bespoke bath room fitting service, including major project
Every year our top-floor flat used to leak in the monsoon. FOUR WALLS inspected the terrace, suggested a proper waterproofing system and completed the work neatly. This year, even with heavy rain, there was no leakage or dampness. Very satisfied with their work and behaviour.
Banerjee
We had serious dampness in our bedroom and living room walls. The team from FOUR WALLS explained the cause clearly, did the repairs and waterproofing step by step and finished on time. They also guided us on when to paint. Now the walls are dry and clean, and the damp smell is gone.
Mukherjee
As a housing society, we struggled with terrace leakage and tank seepage for years. FOUR WALLS handled roof waterproofing, tank treatment and some structural repairs for us. Their quotation was transparent and the work was well supervised. Members are happy that seepage to top floors has stopped.
Maheshtala
We contacted FOUR WALLS for STP waterproofing and epoxy flooring in our small industrial unit. They planned the work around our production schedule and executed it professionally. The epoxy floor is easy to clean and the treated areas have stayed dry. We will surely work with them again.
