Our Professional Waterproofing Services in Kolkata
Roof & Terrace Waterproofing
Terrace and roof leakage is one of the biggest issues in the city. We provide roof treatment for water leakage in Kolkata using suitable membranes, coatings, and treatments based on your slab condition and usage. The result: fewer seepage complaints in top-floor rooms and a structure that’s much better protected.
Bathroom & Toilet Waterproofing
Bathrooms are constant water zones. We treat floors, joints, corners, and pipe areas with proper waterproofing systems before tiling or re-tiling. This helps stop leakage to the flat below or adjacent walls, and prevents damp patches from reappearing beside bathrooms.
Balcony & Chhajja Waterproofing
Balconies, chhajjas, and projections collect a lot of rainwater and often leak into internal walls. Our waterproofing services in Kolkata focus on correct slopes, joint sealing, and surface protection for these exposed areas so your living room and bedrooms stay dry.
Wall & External Surface Waterproofing
If your external walls or boundary walls are letting in moisture, we perform waterproofing with suitable coatings and treatments. This is especially important for walls facing heavy rain or in contact with neighbouring buildings.
Foundation & Ground-Contact Waterproofing (Where Applicable)
In some properties, lower floors and basements face moisture from the ground. We assess these areas and suggest appropriate waterproofing solutions—helpful for selected independent houses or structures with basements.
Repair of Existing Waterproofing Failures
Already did waterproofing once but leakage returned? We inspect the current system, identify the failure points, and then recommend either repair or a full redo, depending on the condition. Our goal is to move you away from constant band-aid fixes.
Steps to Your Dream Space
Turning Your Vision into Reality with the best interior designing company in kolkata
01
Site Visit & Problem Identification
We start with a detailed site visit. Our team checks visible damp patches, peeling paint, ceiling stains, cracks, and ponding areas on roofs or terraces. We also consider age of building, previous repairs, and internal layouts to understand where water might be travelling.
02
Root Cause Analysis
Instead of only coating the visible area, we try to identify the source: is it a cracked slab, open joint, poor slope, plumbing leak, or old failing system? This step is what separates the best waterproofing contractors in Kolkata from basic patching services.
03
Solution Planning & Costing
Based on the issue and area, we recommend suitable treatments and explain them in simple language—no confusing jargon. We also give clarity on roof waterproofing cost in Kolkata, bathroom waterproofing costs, and what is realistically needed so you can make informed decisions.
04
Surface Preparation
We clean the surface thoroughly, remove loose material, and repair cracks and joints. In some cases, we may need to chisel out damaged areas or open up specific lines before treating them. A properly prepared surface is essential for any Calcutta waterproofing company claiming long-term results.
5
Application of Waterproofing System
Once the surface is ready, we apply the chosen system—coating, membrane, chemical treatment, or combination—following correct coverage, overlap, and curing practices. Our application is methodical so the system performs as intended and does not fail due to shortcuts.
6
Testing, Finishing & Handover
Where possible, we test the treated area (like controlled water ponding on terraces) to check performance. Finally, we complete any protective screed, tiling, or finishing layers and leave the surface neat and ready for use or further interior work.
Why Choose RK Interior Designer as Your Waterproofing Contractors in Kolkata?
1. Interiors + Waterproofing Under One Roof
We’re not only a waterproofing company in Kolkata—we’re an interior design and execution team. That means we coordinate waterproofing with tiles, paint, carpentry, and electrical, ensuring finishing layers don’t undo the protection or hide unresolved issues.
2. Practical Experience with Kolkata Buildings
From old Calcutta houses to new high-rises, we’ve seen how water travels through roofs, beams, chhajjas, and walls in our climate. That local experience helps us provide waterproofing services in Kolkata that actually work on real structures, not just in brochures.
3. Focus on Source, Not Just Stains
Instead of only scraping and repainting damp patches, we look for where the water is entering—roof cracks, balcony edges, faulty slopes, pipe joints. This approach is why clients often see us as one of the best waterproofing contractors in Kolkata for long-term relief.
4. Transparent Guidance on Scope & Cost
We explain what really needs waterproofing and where basic repair is enough. You get clarity on treatment area, method, and cost instead of vague promises. When you ask about roof waterproofing cost in Kolkata, we talk in terms of your actual site condition, not random rates.
5. Coordination with Other Trades
Because waterproofing sits between civil work and finishing, we ensure correct sequencing with masonry, plumbing, tiling, and painting. This coordination reduces rework and avoids damage to freshly done work—an advantage you rarely get when you hire disconnected teams.
FAQ
Waterproofing in Kolkata
1. Do you only do roof waterproofing, or bathrooms and balconies too?
We handle all of them—roofs, terraces, balconies, bathrooms, external walls and selected ground-contact areas, as part of our waterproofing services in Kolkata.
2. How do I know if I need waterproofing or just repainting?
If you see dampness, bubbles, or repeated peeling in the same spot, repainting alone won’t help. Waterproofing is needed when water is entering the structure, not just staining the surface.
3. How long does waterproofing work usually last?
It depends on the system used, building condition, and maintenance. During our visit, we’ll tell you what to realistically expect for your specific site.
4. Can you work in stages if my budget is limited?
Yes. We can prioritise the most critical areas first—like roof treatment for water leakage in Kolkata flats or severe bathroom leakage—and plan less urgent work for later.
5. Is waterproofing very messy?
Some dust and noise is expected for repair and prep, but we try to keep the area as contained and clean as possible. Our aim is to fix the problem without turning your home into a permanent construction site.
