    74 Questions

    Installing a new electrical power point in Singapore generally ranges from $80 to $150 per socket. The final cost depends on whether it is a single or double socket, and if the wiring can be tapped from an existing point nearby or requires running completely new casing from the DB box.

    Frequent electrical tripping is usually caused by an overloaded circuit (running too many high-power appliances simultaneously), a short circuit (damaged internal wiring or faulty appliances), or a ground fault. An electrician will use insulation resistance testers to isolate the source of the trip.

    Yes, under Singapore law, any electrical wiring work—including replacing or installing light fixtures, switches, and water heaters—must be performed or supervised by an Energy Market Authority (EMA) Licensed Electrical Worker (LEW) to ensure safety and insurance compliance.

    While simple modifications look easy, DIY electrical work is highly discouraged due to fire risks and fatal shock hazards. Faulty DIY installations can void home insurance policies in Singapore and violate local building safety regulations.

    If your property is more than 20-30 years old, experiences frequent power trips, has visible sparks at sockets, or contains old black/green rubber cables rather than modern PVC-insulated ones, a complete or partial rewiring is highly recommended to handle modern power loads.

    First, check if your neighbors still have power to determine if it is a neighborhood blackout. If it's isolated to your home, check your DB box. If flipping the RCCB switch back up results in an immediate trip again, leave it down and call an emergency troubleshooting electrician right away.

    Absolutely. All cables, circuit breakers, switches, and sockets used during our installations carry the Enterprise Singapore SAFETY Mark and strictly follow the SS 638 code of practice guidelines.

    Most standard power trip diagnostic and fix sessions take between 30 to 90 minutes. Our technician will test individual circuits to locate the faulty line or appliance and repair or isolate it safely.

    For typical residential use in Singapore, routine aircon servicing is recommended once every 3 to 4 months. If you run your aircon daily or overnight, regular maintenance keeps filters clear, helps lower your electricity bills, and prevents sudden water dripping issues.

    Warm air usually points to a few common culprits: clogged air filters restricting flow, a dirty condenser unit outside, a faulty capacitor, or a slow refrigerant gas leak. Our diagnostic checks quickly isolate the exact source of the cooling failure.

    A chemical wash is performed while the unit remains attached to the wall, flushing out the main coils and tray. A chemical overhaul involves completely dismantling the entire indoor unit from the wall to safely treat every hidden component and drain pipe individually, fixing deep slime clogs completely.

    Water leaking is typically caused by a blocked condensation drainage pipe. Over time, dust, bacteria, and slime form a thick jelly inside the narrow pipe, creating a backup. A professional drainage vacuum or flush clears this out instantly.

    No. Refrigerant gas operates in a closed loop and does not get 'consumed.' You only need a gas top-up if there is an active leak in your copper pipe system. We check pressure levels first before suggesting a top-up.

    We strictly use high-quality installation materials suitable for Singapore's humid climate. This includes durable Gauge 22 copper piping, premium Class 1 insulation to minimize condensation issues, and high-quality 3C40 electrical wiring.

    Top reliable choices for local homes include Daikin, Mitsubishi Electric (Starmex), Panasonic, and Samsung. They are highly efficient, handle constant tropical humidity effectively, and replacement parts are readily available.

    A blinking or flashing timer light indicates that the system's internal self-diagnostics have detected an error. This can relate to a fan motor failure, electronic PCB bugs, or low gas pressures. Turning the main isolator switch off and on resets the system, but persistent blinking requires diagnostic testing.

    Clearing a standard toilet bowl or kitchen sink floor choke typically costs between $80 to $150. If the blockage is deeper within the main drainage pipe stack and requires specialized heavy-duty mechanized rotary equipment, prices can adjust upwards transparently.

    Locate your property's main water control valve (usually found near your sub-meter outside an HDB flat or under the sink in condos) and turn it clockwise completely to shut off the water supply. This stops the flooding instantly while you wait for an emergency plumber.

    A continuously running toilet is typically caused by a worn-out rubber flapper valve, a misaligned float ball, or a faulty fill valve inside the water cistern. This allows water to constantly seep into the bowl, which can quietly increase your monthly water bill.

    For basic maintenance like replacing a tap, installing a shower spray, or clearing minor sink blockages, a handyman or proficient plumber is perfectly acceptable. However, major modifications to water service pipes or sanitary discharge systems require a PUB Licensed Plumber by law.

    Slow drainage in floor traps is almost always caused by an accumulation of tangled hair, soap scum, and body oils binding together inside the U-bend trap. Regular cleaning helps, but a deep mechanical flush removes the hardened buildup completely.

    Key indicators include sudden unexplainable spikes in your PUB water bill, peeling paint or damp water patches forming on walls, moldy smells, or the sound of running water when all taps are closed. You can verify by checking if your water meter dials spin while no appliances are running.

    Yes, we use durable, high-quality replacement parts compliant with Singapore standard requirements, including corrosion-proof PVC pipes, premium brass valves, and high-tensile stainless steel braided hoses.

    Yes, we offer installation-only services. If you have purchased your own toilet bowl, water heater, or designer faucet from a retail outlet, our plumbers will carry out the secure installation and testing perfectly.

    Our full T&C process covers hardware stability, line connectivity, and storage verification. For fiber, we provide an OTDR optical power reading report verifying decibel loss limits. For CCTV, we run video signal integrity audits, test local motion alert schedules, and perform remote mobile-app connectivity checkouts.

    Yes. During our commissioning step, we bridge your Network Video Recorder (NVR) with your router. This lets you securely monitor live video feeds, review past timeline logs, and get immediate motion alerts on your smartphone or desktop from anywhere via encrypted cloud apps.

    Wireless security cameras are susceptible to local signal interference, crowded Wi-Fi networks, and dropouts across concrete walls. Wired networks provide stable bandwidth, prevent wireless security exploits, and guarantee zero frames are dropped when logging records to your storage drives.

    This depends entirely on your system parameters: how many cameras you have, the resolution, and the size of your storage drive. Typically, a standard configuration delivers 14 to 30 days of storage data. Once storage fills up, the system automatically loops and replaces the oldest records.

    An Optical Time-Domain Reflectometer (OTDR) is an diagnostic system that injects light pulses into a fiber line. It measures how much light reflects back to discover connection quality, map internal line distance, and locate pinpoint physical faults or poor splices that cause packet loss.

    Yes, Singapore has guidelines under the Personal Data Protection Act (PDPA). Security cameras must point strictly within your property boundaries. For HDB estates, external cameras must not face directly into neighboring flats without permission or town council approval letters.

    Fiber optic cores are glass components that cannot be repaired with regular tape or wire nuts. If a break occurs, our team locates the damage, cuts back the line, and uses precision fusion splicers to rejoin the microscopic glass fibers cleanly, keeping signal loss to a minimum.

    Yes, we can include an Uninterruptible Power Supply (UPS) battery backup system inside your network rack during commissioning. This ensures your server switch, NVR recorder, and essential cameras keep operating cleanly during sudden power cuts or trips.

    Yes. Modern click-lock luxury vinyl flooring can be installed overlay style over flat, existing tiles without hacking. However, the floor lines must be clean and structurally sound. Any broken tiles or deep grout joints are leveled using specialized subfloor compounds before installation.

    For a standard 3-room or 4-room HDB flat, professional overlay flooring installation typically takes 1 to 2 days. The click-lock system is efficient, requires no toxic wet glues, and you can comfortably walk on the floor immediately after completion.

    Cabinet doors usually sag or pop open because the internal spring tensions inside the hinges have worn down or the screw anchor points in the chipboard have stripped. Our carpenters replace these with heavy-duty soft-close hydraulic hinges to fix the alignment cleanly.

    Solid wood parquet flooring usually benefits from a deep sand and varnishing process every 7 to 10 years, depending on foot traffic and direct sunlight exposure. This completely removes surface oxidation, deep scratches, and localized pet stains.

    Solid wood (like parquet) is natural timber that offers exceptional luxury and can be repeatedly restored but is vulnerable to water spills and termites. Engineered vinyl flooring (SPC) is a composite stone-plastic mix that is 100% waterproof, highly scratch-resistant, and ideal for humid Singapore settings.

    Yes. If an under-sink area gets waterlogged and swells, we can remove the damaged base section, structural supports, and rotted laminate, replacing them with moisture-proof Marine Plywood panels to restore structural integrity.

    Yes. If your HDB entrance door faces an escape route or elevator lobby, it must strictly be a certified fire-rated door. Replacing it requires submitting an application to HDB through a licensed vendor. Standard internal bedroom doors do not require these official permits.

    Wood and vinyl expand and contract slightly with temperature shifts. We always leave a tiny, strategic 3-5mm expansion gap along the walls. This gap is neatly concealed using matching skirting boards or flexible, high-quality waterproof silicone caulking.

    Generally, simple lightweight drywall partitions do not require formal HDB permits as long as they do not load structural pillars or modify emergency exit floor plans. However, you must ensure that your new room configuration still maintains adequate natural ventilation and lighting entry inside the flat.

    Standard plasterboard alone cannot hold heavy hanging furniture. If you plan to hang heavy objects like a TV console or kitchen storage cabinet, you must inform us beforehand. Our installers will reinforce the internal framework with thick plywood backings or extra metal studs to distribute the load safely.

    A standard partition consists of a hollow metal track system faced with 9mm or 12mm plasterboards on both sides. A soundproof partition upgrades this by filling the hollow inner cavity with dense, sound-damping Rockwool acoustic insulation materials, and often uses thicker acoustic boards to reduce decibel leaks significantly.

    Repairing a localized patch of water damage typically takes a few hours over 1 to 2 days. On day one, we cut out the rotted damp sections, secure the framing, and apply the initial structural plaster compound. We return on day two to execute a fine sand and coat it with a stain-blocking paint sealer.

    Cracks occur due to natural structural micro-vibrations or cheap jointing materials. We prevent this by layering high-tensile fiberglass mesh tape along every single board joint before applying multi-layered skim compounds. This distributes surface stresses cleanly and eliminates joint cracking completely.

    We strictly use specialized Moisture-Resistant Gypsum Boards (commonly called green boards) inside high-humidity environments like bathrooms. These are embedded with silicone wax cores that stop water absorption, prevent sagging, and inhibit mold development.

    Yes. One of the main benefits of a false ceiling or cove light box is the open internal layout space it provides. It allows electricians to safely route wiring loops and cut precise custom holes for downlights or linear LED extrusion profiles wherever you prefer.

    A standard residential drywall partition measures roughly 75mm to 100mm in total thickness. This layout uses a internal 50mm or 75mm galvanized structural steel track frame, finished with a layer of 12.5mm gypsum boards secured neatly on each side.

    Painting a typical 4-room HDB flat normally takes 2 to 3 days. Day one focuses heavily on moving furniture, wrapping items, scraping old layers, and patching wall flaws. The subsequent days are dedicated to sealer layout and applying the dual finishing topcoats.

    Skim coating involves applying a thin layer of plaster paste across concrete walls to hide structural waves, rough patches, or deep nail holes. If your walls look bumpy under downlights, show coarse sand textures, or have numerous pitting holes, a full plaster skim coat is needed before painting.

    Flaking occurs when persistent moisture and steam from hot showers weaken the paint's bond with the plaster below. Over time, alkali salts leach out of the concrete, turning the paint powdery. We fix this by scraping it bare, laying an oil-based anti-alkali sealer, and applying moisture-proof paint.

    Yes, skipping the sealer is the leading cause of paint failure. A sealer acts as an adhesion bridge that binds chalky wall residues, neutralizes concrete alkalinity, and prevents the porous wall from unevenly absorbing the final topcoat colors.

    Absolutely. We offer premium eco-friendly paint ranges like Nippon Paint Odour-less All-in-1 or Dulux Wash & Wear. These formulations feature near-zero Volatile Organic Compounds (VOCs), emit zero toxic chemical odors, and allow you to sleep in the rooms comfortably on the same day.

    We do not simply paint over mold, as it will rot through the new layer. Our team sprays the area with specialized anti-fungal washes to destroy active root spores. Once sterilized and completely dry, we seal the surface with a specialized stain-blocking primer before applying anti-mould paint.

    We take care of the heavy lifting. Our team shifts large furniture pieces to the center of each room and seals them completely using clean, protective plastic drop rolls. We only ask that you put away small, fragile valuables and clothes beforehand.

    Matte finishes reflect no light, making them exceptional at hiding wall plaster flaws, though they are harder to scrub clean. Satin or eggshell finishes provide a soft pearl sheen that balances washability with smooth looks. Gloss or enamel paints are shiny, highly durable, and ideal for timber doors or iron gates.

    Polyurethane (PU) injection grouting involves drilling small holes into the underside of a leaking concrete ceiling and inserting mechanical packers. Hydrophobic PU chemical resin is then pumped in under high pressure. When it meets moisture, it expands up to 20 times its volume into a dense, flexible rubber seal that blocks all water pathways.

    Not necessarily. If the structural concrete slab is sound and the leak is primarily due to compromised tile grout lines, our no-hacking chemical waterproofing treatment can solve it. We apply a deep-penetrating water-repellent compound that infuses into the pores of the floor substrate to create a subsurface hydrophobic shield.

    Depending on the repair methodology used, professional residential waterproofing warranties generally range from 1 year to 5 years. For instance, targeted PU injection grouting typically comes with a 1 to 2-year warranty, while full-hacking bathroom or roof membrane replacements often include up to a 5-year coverage period.

    Under HDB's co-management policy, responsibility for an inter-floor leak is shared equally between the upper-floor and lower-floor flat owners. Both neighbors must cooperatively arrange for inspection and split the repair costs, unless the leak originates from an external wall or public pipe infrastructure.

    Active water leaks typically display expanding watermarks, blistered paint, or visible dripping, and the concrete stays damp to the touch. High humidity usually causes surface-level dark mold spots without structural bubbling. We use precise electronic moisture meters to verify subsurface dampness levels.

    Waterproofing failures are mostly caused by house structural settling, micro-vibrations, or natural material aging. As a building settles, micro-cracks form in the concrete floor slab. If the old chemical or screed membrane lacks sufficient elastomeric flexibility, it ruptures along those stress lines, letting water pass.

    Outdoor membrane applications require a completely dry substrate to bond properly. If it rains onto exposed concrete, moisture gets trapped inside the pores, leading to blistering later. While we schedule outdoor roof projects around fair weather windows, internal fixes like PU grouting can be safely executed anytime.

    A water ponding test involves blocking floor drainage outlets in a newly waterproofed area, filling the floor with roughly 25-50mm of water, and leaving it submerged for 24 to 48 hours. This structural test verifies that the newly applied membrane is completely free of pinholes or weak seams before final tiling begins.

    Most standard commercial tenancy agreements require you to return the empty space back to a clean 'bare shell' state. This means removing all temporary drywall dividers, partitions, built‑in floor carpets, cabinetry, and custom electrical fixtures while painting everything back to building white.

    Yes. Any structural remodeling that involves hacking down brick or concrete walls, removing wall tiles, or altering floor screeds requires a formal hacking permit approved by HDB. Simple dismantling of timber wardrobes or kitchen cabinets can be executed without permits.

    A standard 1,000 square foot commercial office footprint typically requires 3 to 5 days to completely restore. Larger spaces or units containing heavy brick masonry works, extensive ceiling grids, or complex mechanical layout systems may require 1 to 2 weeks of field time.

    Yes. We operate alongside Licensed Electrical Workers (LEW) and fire safety specialists to safely terminate custom wiring, loop smoke detectors back to standard setups, and adjust fire sprinkler heights according to Singapore Civil Defence Force fire safety regulations.

    Most commercial buildings and condominiums restrict noisy operations (like pneumatic tile or concrete drill hacking) strictly to weekdays between 9:00 AM and 5:00 PM. Noisy tasks are completely banned on weekends and public holidays to protect surrounding neighbors.

    We manage the entire haulage phase. Debris is sorted on‑site, packed tightly into heavy‑duty disposal bags, and transported via open‑top lorries or roll‑on bins directly to NEA‑authorized recycling and waste management facilities. We provide disposal invoice logs if required by your building management.

    Most HDB town councils provide free removal for up to 3 bulky items per household each month. However, this service excludes heavy custom built‑in woodwork, kitchen cabinets, full‑size wardrobes, electronic waste, or items from commercial properties. They also require you to move the items down to the void deck yourself.

    No, you don't have to lift a finger. Our crew carries specialized power tools, impact drivers, and crowbars to dismantle large wardrobes, bed frames, and study setups safely on‑site within minutes.

    Our pricing is transparent and depends on two things: the total volume your items take up inside our standard 10‑foot or 14‑foot lorries, and how complex the dismantling work is. We offer upfront quotes based on pictures sent via WhatsApp, covering labor, transit, and official dumping taxes.

    Our standard 10‑foot canopy lorries are selected specifically to clear the 2.1‑meter height limits common in underground condo loading zones and HDB multi‑storey structures. If an entry is unusually low, our crew unloads at designated surface areas and uses rolling trolleys.
