Do you provide free quotations?

Yes. All quotations are free and issued in writing before any work begins. We break down costs clearly — labour, materials, and any additional items — so you know exactly what you are paying for. We do not start work until you have approved the quote in writing.

Can RumahPro handle plumbing, electrical, and renovation together?

Yes — this is one of our key advantages. Most small renovation firms subcontract either plumbing or electrical work, which adds coordination time and cost. RumahPro handles MEP (mechanical, electrical, plumbing) works in-house alongside carpentry, tiling, painting, and full renovation scope. One contractor for the full job.

How long does a typical bathroom or kitchen renovation take?

A full bathroom renovation typically takes 7 to 14 working days depending on scope, tile selection, and fixture availability. A kitchen renovation typically takes 10 to 21 working days. We provide a project timeline alongside the quotation so you know when to expect completion before work starts.

Is RumahPro a licensed and insured contractor?

Our tradespeople hold the relevant certifications for electrical and plumbing works. Renovation projects are covered under contractor insurance. We will provide documentation upon request during the quotation process.

Waterproofing & Leakage Repair in KL & Selangor — Diagnose First, Then Fix Properly

Name: RumahPro
Telephone: +6011-6999-2619

A leaking roof or bathroom does not just cause damage to the surface you can see. Water tracking through your building structure for months has usually caused significantly more damage than the visible stain on the ceiling suggests.

Waterproofing & Leakage Repair in KL & Selangor — Diagnose First, Then Fix Properly

The most common waterproofing failure in Malaysia is not the original installation — it is the repair. A sealant applied to the surface of an active leak, without identifying where the water is actually entering, will fail within one or two monsoon seasons. The water finds a new path. The stain returns. The cycle repeats.

RumahPro's approach to leakage repair starts with diagnosis — finding where the water is actually entering, not just where it is appearing. The repair is only specified after we understand the source.

Roof Leakage Detection & Repair

Roof leaks in Malaysian homes are commonly caused by cracked or displaced roof tiles, failed roof membrane on flat roof sections, blocked or damaged flashings at wall junctions, and failed waterproofing at parapet walls and roof penetrations.

We inspect the roof systematically — exterior surface, drainage paths, flashing condition, and interior soffit — before specifying any repair. Temporary patches without addressing the root cause are not a service we offer.

Balcony & Terrace Waterproofing

Balconies and terraces in KL and Selangor condos and landed homes are a common source of water ingress into the unit below. The junction between the balcony slab and the building wall is the most frequent failure point. We apply appropriate membrane systems, extend waterproofing up the wall to the correct height, and address drain sump sealing and door threshold details commonly missed in surface-only repairs.

Wall Seepage — External & Internal

Expansion Joint Sealing

Expansion joints in concrete structures — at floor-to-wall junctions and at structural movement joints — are a common leakage path as the original sealant ages and loses flexibility. We re-seal expansion joints using sealant systems specified for the movement and exposure conditions.

Frequently Asked Questions

My ceiling is stained but the roof looks intact. Where is the water coming from? expand_more

A ceiling stain directly below an intact roof area usually indicates one of three sources: a leaking pipe inside the ceiling void, a leaking bathroom from the unit above, or water tracking laterally from a nearby penetration. We carry out a systematic diagnosis to identify the true source before opening any ceiling or recommending repair work.

Can waterproofing be applied without hacking existing tiles? expand_more

For some above-ground applications such as balconies and external walls, surface-applied waterproofing can be effective without hacking. For bathroom floors, a surface application over existing tiles cannot reliably seal the tile-to-drain and tile-to-wall junctions — which are the most common failure points. For active bathroom leakage, hacking and full reapplication is almost always the correct long-term solution.

How long does waterproofing last? expand_more

Quality membrane waterproofing systems applied correctly to a properly prepared substrate typically have a service life of 10 to 15 years. The most common reasons for early failure are: application to a damp substrate, incorrect membrane thickness, inadequate coverage at junctions, and mechanical damage during subsequent construction activity.

My downstairs neighbour is complaining about water from my bathroom. What should I do? expand_more

Stop using the bathroom where possible and contact us for an urgent assessment. Active leakage to a lower unit can escalate into a formal management complaint. A proper written diagnosis and repair scope demonstrates to building management that you are addressing the issue responsibly.
