Frequently asked questions

Most roller shutter installations take one to two hours per window, so a standard home with two or three windows can typically be completed in a single day. Installation time varies depending on the size of the opening, whether scaffolding is needed, and any electrical work required for motorised shutters. Our team will give you an estimated timeframe when you book your appointment. For more on what a professional installation involves, see our guide to roller shutter installation.

Yes — roller shutters are one of the most effective ways to regulate temperature in an Australian home. When closed, they create a thermal barrier between the window and the interior, reducing heat transfer in summer and retaining warmth in winter. DHE Group's roller shutters use foam-filled aluminium slats that provide additional insulation, which can meaningfully reduce your reliance on air conditioning and lower your energy bills over time. Learn more in our article on how roller shutters reduce heat, or find out why your house gets so hot on sunny days.

Roller shutters can reduce external noise levels by up to 50%, making them a popular choice for homes near busy roads, flight paths, or noisy neighbourhoods. The degree of noise reduction depends on the slat type — foam-filled slats perform better acoustically than hollow profiles. It's worth noting that roller shutters reduce noise through windows specifically; sound can still enter through rooflines, doors, or other openings, so they work best as part of a broader approach to acoustic comfort. Read our in-depth guide on how roller shutters help with noise.

For most Australian homeowners, roller shutters are a strong investment. They improve security, reduce heat and noise, provide privacy, and can increase the resale value of a property. The ongoing energy savings from reduced air conditioning use also help offset the upfront cost over time. Whether they're worth it for your situation depends on your priorities — if security, privacy, or temperature control are important to you, roller shutters typically deliver excellent long-term value. See our overview of the benefits of residential roller shutters and how they can increase your home value.

Roller shutters are most commonly made from aluminium, which offers the best combination of strength, light weight, and corrosion resistance. DHE Group manufactures its shutters using marine-grade, rust-free aluminium with a powder-coated finish that resists fading, UV damage, and harsh weather conditions. Some shutters use foam-filled slats for improved thermal and acoustic performance. Steel shutters exist but are heavier and less common for residential applications in Australia. For a full breakdown of what's available, see our guide to types of roller shutters in Australia.

Well-maintained roller shutters typically last 15 to 20 years or more. Lifespan depends on the quality of the materials, exposure to coastal or harsh environments, and how regularly the shutters are serviced. Aluminium shutters with a quality powder-coat finish are particularly durable. Lubricating the guides annually and cleaning the slats every few months will significantly extend the life of your shutters. DHE Group's roller shutters are backed by a manufacturer's warranty — see our warranty and repairs page for details, or read our roller shutter maintenance guide.

Yes, roller shutters can be retrofitted to virtually any window or door opening. For existing buildings, surface-mounted headboxes and guide channels are fixed to the wall above and beside the opening, meaning no structural alterations are required. In most cases, a professional retrofit can be completed in a single visit. DHE Group handles retrofit installations regularly across Adelaide and South Australia — we'll assess the opening during your free measure and advise on the best fitting method for your home. Contact us to arrange a time.

Manual roller shutters are operated by hand using a strap, crank, or push-up mechanism. They are simpler, lower cost, and require no electrical installation. Motorised roller shutters use an electric motor and can be controlled via a wall switch, remote control, or smart home system. Motorised operation is more convenient — particularly for larger or higher openings — and is the preferred option for most homeowners today. DHE Group offers both manual and motorised options, and existing manual shutters can often be retrofitted with a motor at a later stage. Learn more in our article on battery-operated roller shutters and choosing the right roller shutter motor.

Cleaning roller shutters is straightforward. With the shutter fully closed, rinse the slats down with a garden hose to remove loose dust and debris. Then wipe the slats with a soft cloth or sponge and a mild, non-abrasive cleaning solution, working vertically up and down (not side to side, which can catch on slat edges). Rinse thoroughly and allow to dry before opening. Aim to clean your shutters every three to four months, or more frequently if you live near the coast or in a dusty environment. For step-by-step instructions, read our full guide on how to clean roller shutters.

Rattling is usually caused by one of three things: loose guide channels, worn bottom bar seals, or insufficient lubrication. Start by lubricating the guides with a silicone-based spray. Check that the guide channels are still firmly fixed to the wall and tighten any loose screws. If the bottom bar seal is worn or missing, it can allow the shutter to move in the wind — a replacement seal is an inexpensive fix. If rattling persists after these steps, contact DHE Group for a service or warranty inspection.

If your roller shutters are not opening or closing correctly, start with these checks. For electric shutters, confirm that the power supply is active — look for indicator lights on the motor control unit and try switching off and back on at the wall. If the shutter feels stiff or stuck, the guides may be dry or obstructed; clear any debris and apply a silicone-based lubricant. For shutters that only close partway, check that the proximity sensors are aligned and clean — dirty sensors are a common cause of partial closure. If the motor is overheating from extended use, allow it to rest before trying again. If these steps don't resolve the issue, submit a request via our warranty and repairs page.

Lubricating your roller shutters once a year is the single most effective maintenance step you can take. Use a silicone-based lubricant spray. Apply the lubricant to the plastic clips at the top of each guide channel and along the inside of the tracks. Open and close the shutter a few times after application to distribute the lubricant evenly. Regular lubrication prevents sticking, rattling, and premature wear on the motor or winding mechanism. Our full roller shutter maintenance guide covers this and other servicing steps in detail.

Yes — roller shutters are widely used across both residential and commercial applications. For homes, they provide security, privacy, temperature control, and noise reduction. For commercial properties, they offer high-security protection for shopfronts, warehouses, and office windows, and are built to handle more frequent operation cycles. DHE Group installs roller shutters for both domestic and commercial clients across Adelaide and South Australia.

PVC outdoor blinds are made from a solid, clear or tinted vinyl that provides full weather protection — blocking wind, rain, and cold while keeping your outdoor area usable year-round. Mesh blinds are made from an open-weave fabric that filters sunlight and reduces glare without completely blocking airflow or your view. PVC is the better choice for enclosed entertaining areas or cold-climate use; mesh suits patios where ventilation and a more open feel are preferred. DHE Group supplies both — our team can help you choose based on your space, orientation, and how you use the area. See our comparison of mesh vs PVC outdoor blinds.

PVC outdoor blinds can effectively stop rain and significantly reduce wind penetration, making them a popular choice for enclosed patios and alfresco areas. Track-guided systems provide the best wind resistance, as the fabric is held firmly in side channels rather than hanging free. Mesh blinds filter wind but will not stop rain. For maximum protection in exposed or high-wind locations, we recommend a track-guided PVC system. Read our detailed article on whether outdoor blinds can stop rain and wind, or see how they perform in windy conditions.

Yes — outdoor blinds are one of the most effective ways to reduce heat entering your home through windows and outdoor living areas. By blocking or filtering sunlight before it reaches the glass, they prevent heat from building up inside, which can significantly reduce your air conditioning load in summer. Mesh blinds filter UV and reduce glare while allowing airflow; PVC blinds provide a stronger thermal barrier. For tips on managing summer heat, see our article on beating the summer heat with outdoor blinds and why houses get so hot on sunny days.

PVC outdoor blinds are highly water-resistant and will handle rain effectively when the blind is fully closed and the side edges are secured. They are not fully waterproof at the joins between panels or at the top pelmet in heavy, driven rain, but they provide excellent protection for most weather conditions. Mesh outdoor blinds are not designed to stop rain — water passes through the open weave. If full weather protection is your goal, a PVC blind with a track-guided system is the recommended option. Our article on the waterproof qualities of outdoor blinds explains this in more detail.

Outdoor blinds extend the usable area of your home by transforming an open patio, deck, or alfresco into a sheltered, comfortable space year-round. Key benefits include sun and UV protection, wind and rain reduction, improved privacy, reduced glare, and lower indoor temperatures in summer. They also protect outdoor furniture from fading and weather damage. For entertaining areas, outdoor blinds can effectively add a new room to your home without the cost of a full enclosure. Read our full overview of the reasons outdoor roller blinds are a must for any home and the major advantages of installing outdoor blinds.

Yes — PVC outdoor blinds are particularly effective in winter, keeping cold winds out and retaining warmth in your outdoor entertaining area. Many Adelaide homeowners use them to get year-round use from their alfresco spaces by closing the blinds on cold or wet days and opening them up when the weather is fine. Mesh blinds are less suitable as a winter solution since they allow cold air to pass through. See our article on outdoor cafe blinds for winter and how to make your patio cosy in winter for ideas.

Manual outdoor blinds are operated by hand using a strap, spring roller, or crank mechanism. They are straightforward to use, require no electrical installation, and are typically lower in cost. Motorised outdoor blinds are controlled by a wall switch, remote, or smart home system and are ideal for larger or harder-to-reach blinds, or when you want to operate multiple blinds simultaneously. At DHE Group we offer both options — our team will advise which is more practical for your space during your free measure and quote. Get in touch to book yours.

To clean outdoor blinds, lower them to the fully closed position and hose them down to remove loose dust and debris. For tougher marks, use a soft cloth or sponge with a mild detergent diluted in warm water, working from top to bottom. Avoid abrasive cleaners or high-pressure washing, which can damage the fabric surface or stitching. Rinse thoroughly and allow to dry fully before rolling up to prevent mould or mildew forming in the rolled section. Aim to clean your blinds every two to three months. Our guide on how to clean outdoor blinds covers this step by step.

In most cases, outdoor blinds installed on an existing structure such as a patio, pergola, or verandah do not require council approval in South Australia. However, rules can vary depending on your local council, whether your property is heritage-listed, or if the structure itself requires approval. We recommend checking with your local council before proceeding if you have any uncertainty. DHE Group can advise on typical installation requirements during your free measure and quote — contact us to arrange a time.

Yes — outdoor blinds are one of the most popular additions to pergolas and decks. They can be mounted to timber, steel, aluminium, brick, or concrete structures, and custom-made to fit virtually any opening size. Installing blinds on a pergola or deck transforms it from a seasonal space into a year-round outdoor room, protected from sun, wind, and rain. DHE Group supplies and installs outdoor blinds for patios, pergolas, and decks across Adelaide and South Australia. Find inspiration in our article on combining outdoor blinds with your pergola, or browse the full outdoor blinds range.

DHE Group offers plantation shutters in two materials. Imported PVC is the most popular choice — moisture-resistant, durable, easy to clean, and suitable for any room including bathrooms and kitchens. Aluminium plantation shutters are the most durable option and are particularly suited to external applications and high-traffic commercial environments. Our team can walk you through the differences and help you choose the right option for your home during your free measure and quote — get in touch to book yours.

For most Australian homeowners, plantation shutters are considered one of the best long-term window treatment investments. They are durable (lasting 15 to 25 years with proper care), require minimal maintenance, provide excellent light and privacy control, improve thermal insulation, and add to the resale value of a property. Unlike curtains or blinds, plantation shutters are often noted by real estate agents as a premium feature. The higher upfront cost compared to blinds is offset by their longevity and the value they add. Read our article on the 6 benefits of plantation shutters and whether plantation shutters are still in style.

High-quality plantation shutters typically last between 15 and 25 years or more, depending on the material and environment. PVC shutters are extremely durable and can last 20 to 30 years with minimal maintenance, making them an excellent long-term investment. Aluminium shutters offer exceptional longevity, particularly in external or high-traffic applications. Regular cleaning is the main upkeep required to keep either material looking its best. DHE Group's plantation shutters come with a manufacturer's warranty — contact us for details when booking your quote.

Yes — plantation shutters are one of the better-insulating window treatments available. When the louvres are closed, they create an air pocket between the shutter and the glass that helps retain heat in winter and block heat in summer, reducing your reliance on heating and cooling systems. Both PVC and aluminium shutters insulate well, with PVC providing the added benefit of moisture resistance for wet areas. Read about how window treatments improve energy efficiency and the full range of plantation shutter benefits.

The main difference is the width of the louvres (slats). Traditional shutters typically feature narrow louvres of 25–50mm, giving a more colonial or heritage look. Plantation shutters have wider louvres — typically 63mm, 76mm, or 89mm — which allow more light in when open, give better views to the outside, and create a cleaner, more contemporary appearance. Plantation shutters also feature adjustable louvres that can be tilted to precisely control light and privacy without opening the full panel, which traditional solid-panel shutters do not offer.

Yes — plantation shutters can be fitted over sliding doors using bi-fold or sliding panel configurations that glide along a top track, allowing full access to the door without needing to remove the shutters. This is one of the most popular applications for plantation shutters in Australian homes. DHE Group offers purpose-built solutions for sliding door openings — see our guide to plantation shutters for sliding doors or our complete guide to bi-fold plantation shutters.

Yes — PVC plantation shutters are an excellent choice for bathrooms. They are moisture-resistant, will not warp, swell, or crack in humid conditions, and are easy to wipe clean — making them far more practical in wet environments than fabric-based window treatments. Aluminium plantation shutters are also suitable for bathrooms, particularly for external-facing windows. DHE Group's PVC and aluminium plantation shutters are both well-suited to high-humidity environments. Read our article on plantation shutters in bathrooms for more detail.

Plantation shutters provide excellent light control but are not a full blackout solution in the way block-out roller blinds are. When the louvres are fully closed, they significantly reduce light and UV coming through the window. However, some light will filter in through the gaps between louvres and around the panel frame. For rooms requiring complete darkness — such as bedrooms or home theatres — plantation shutters work well when combined with a block-out blind or curtain behind them. Read our article on whether plantation shutters are blackout and how to achieve the best light control for your bedroom.

Plantation shutters are one of the easiest window treatments to maintain. For regular cleaning, use a microfibre cloth or feather duster to wipe each louvre individually — work from top to bottom with the louvres tilted open to access both sides. For a deeper clean, dampen the cloth with warm water and a small amount of mild detergent. Avoid soaking the slats or using abrasive cleaners, particularly on timber shutters. PVC shutters can handle more moisture and are quicker to clean. A quick dust every one to two weeks keeps them looking their best. See our full guide on how to clean plantation shutters at home.

From the time you approve your quote, most DHE plantation shutter orders are installed within 3–8 weeks. Imported PVC shutters usually take 6–8 weeks. Aluminium lead times vary by project — our team will confirm your specific timeframe when you receive your quote.

Yes — plantation shutters are widely regarded by Australian real estate agents as a premium feature that can increase a property's appeal and market value. Unlike curtains or blinds, they are typically included as a fixture when a home is sold, and buyers perceive them as a quality upgrade. Their timeless aesthetic suits a wide range of home styles, and their durability means they are unlikely to need replacing before a sale.
