Frequently asked questions about waterproofing

It depends on the area, the condition of the surface, the system and access. We don't price from photos alone because the cause decides the treatment. After the inspection you get a written, itemised quotation, so you can see exactly what you're paying for.

Yes. We visit, diagnose the problem and give you a written quotation, with no obligation to go ahead.

Quotes usually differ in what's included: surface preparation, crack and junction repairs, the system and its thickness, and testing. Ask every contractor to itemise these — ours always are.

For simple jobs we can give a rough range from photos, but a firm price needs an inspection. Leaks often start somewhere other than where they show up.

Payment terms are set out in your quote before work starts. Larger jobs are usually paid in stages as the work is completed.

We look at the problem area and everything around it: the surface above, junctions, outlets, plumbing and the room below. We take moisture readings and, where needed, run flood or pressure tests. Then we explain the cause in plain language.

Most home inspections take under an hour. Larger or commercial properties take longer and may need a second visit for testing.

Yes, or someone who can give us access and tell us when the problem appears — for example, only in heavy rain or only when the shower is used.

Clear access to the affected areas, and any photos or videos of the leak when it was active. If the problem is in a flat below or above yours, let the neighbours know we may ask to look.

Small repairs can be done in a day. Most terraces and bathrooms in a flat or bungalow take a few days to a week, including curing and testing. Your quotation includes a schedule.

Surface preparation can be noisy and dusty for a day or two. We protect floors and furniture, contain dust where we can, and clean up every day.

Almost always. Terrace and outside work doesn't affect your living space. A bathroom may be out of use for several days, so we'll plan around that with you.

Some repairs, like injection grouting, work in wet conditions. Most coatings need a dry surface, so in the monsoon we work in dry spells and protect the area if rain arrives. The best time to waterproof a terrace or external wall is between October and May.

There isn't one best system. PU membranes suit exposed terraces, crystalline treatments suit basements under water pressure, and epoxy grout suits bathroom joints. We recommend based on the surface, its exposure and how it's used.

Professional-grade systems from established manufacturers. Your quotation names the exact product for each part of the job, and we can share its technical data sheet.

No. Waterproof paints help on vertical walls, but terraces, bathrooms and basements need membranes or treatments designed for standing water or water pressure.

For indoor work we favour low-odour, water-based systems. Where a solvent-based product is needed, we ventilate the area and tell you how long to keep it clear.

Keep the outlets and drains clear, sweep away debris and plant growth, and avoid dragging heavy objects or drilling into the surface. A quick check every May, before the monsoon, catches problems early.

Once a year is sensible, ideally between March and May, before the monsoon. Large commercial roofs benefit from an inspection twice a year.

Yes, but talk to us first. Mounts and pipes need to be detailed so they don't puncture the membrane — drilling straight through is one of the most common causes of new terrace leaks.

Avoid acid-based cleaners on grout and sealants, and wire brushes or pressure washers on coatings. Mild detergent and a soft brush are enough.

Call, send a WhatsApp message or fill in the form on this site. Tell us what's happening and where, and we'll arrange a time that suits you.

We call you back and agree a visit time that suits you. Active leaks get the earliest slot we have.

Yes. Call us for urgent leaks. We'll talk you through immediate steps to limit damage and arrange the earliest visit we can.

We work across Mumbai, Thane and Navi Mumbai — the areas are listed on our Service Areas page. If you're nearby but not listed, ask us.

Between October and May, when surfaces are dry and coatings can cure properly. March to May is the busiest time of year for waterproofing in Mumbai, so book your inspection early rather than waiting for the first leak of the monsoon.

Yes. We inspect the terrace, external walls, tanks or common areas, explain the findings to the committee and give a written proposal, with the work phased so residents aren't disrupted.

Yes. We handle offices, shops, hotels, hospitals, housing societies, warehouses and factories, with method statements and safety documentation.
