Buying New Carpet Tips

Buying carpet tips matter more than most people realise. The wrong choice will not last, and it can leave you disappointed with your home for years. Whether you’re an Auckland homeowner, landlord, or property manager, this guide will help you choose carpet that suits your household, your budget, and your health.

To make a confident choice, you’ll want to weigh up carpet type, fibre, pile, underlay, and warranty before you sign anything. Furthermore, if anyone in your home has asthma or allergies, a few extra checks are worth doing first. Below, we’ve pulled together our best buying carpet tips, built on 35 years of hands-on experience in Auckland homes.

Quick checklist before you buy:

• Check the carpet’s performance rating, fibre type, and any health or allergen considerations.
• Confirm the pile density and twist match how the room will be used.
• Ask what the warranty actually covers, and what voids it.
• Choose a reputable, established carpet dealer.
• Budget for quality underlay — it’s not optional.

Buying Carpet Tips For Asthma Allergies Sufferers

As a severe asthmatic myself, this is a subject I take personally. My name is Graeme Stephens of Steam ‘n’ Dry. With 35 years in the carpeting industry, I’ve worked alongside the Asthma Society and hard-flooring specialists, and I’ve followed guidance such as the Higher Standards for Indoor Air Quality and New Zealand’s Carpet Cleaning Standards. Combined with feedback from carpet manufacturers and my own experience, here’s what I’ve found:

1. Hard flooring can suit asthmatics, provided it’s vacuumed and mopped regularly. Unlike carpet, hard floors don’t trap dust, mites, germs, and pollen deep within a pile — these particles rest on the surface instead. However, walking across a hard floor can still stir allergens back into the air. Therefore, hard flooring isn’t automatically the safer option; it depends on how well it’s maintained.
2. Wool carpet is often marketed as allergy-friendly, but my own experience says otherwise. As natural wool fibres break down, they release fine lint into the air. When you walk across wool carpet, this lint and any trapped allergens are disturbed and released, which can trigger inflammation and wheezing in sensitive people.

This lines up with wider research. Studies on house dust mite allergen (Der p 1) in New Zealand homes have found that carpeted floors carry significantly higher allergen levels than hard flooring, and that allergen levels drop sharply after carpet removal or regular deep cleaning. New Zealand’s climate — mild and often humid — happens to suit dust mites particularly well, which is one reason floor coverings matter more here than in drier climates.

Wool Carpet and Asthma

Wool carpet retains moisture after a weekly vacuum, and as a natural fibre, it’s often the first thing in a home to develop mould. Wool is also porous, so it holds onto dirt and pollen more readily. When you walk on it, these particles can be released into the air.

As a result, we don’t recommend wool carpet for households where someone has asthma or a respiratory allergy. Alongside weekly vacuuming, we recommend truck-mounted hot steam cleaning above 70°C every three months to remove and kill dust mites and allergens.

Synthetic Carpet (Polypropylene)

Polypropylene is the most common synthetic carpet fibre in Auckland homes. It’s impermeable and hard-wearing, and it doesn’t let dust and allergens sink into the fibre itself. Because of this, allergens tend to sit on the surface and are released each time you step on the carpet — though this is manageable with regular weekly vacuuming. Six-monthly truck-mount hot steam cleaning above 70°C helps keep dust mites and allergens under control.

Solution-Dyed Nylon Carpet

Solution-dyed nylon is similar to polypropylene, but softer and more full-bodied — a solid option for asthmatics. There can be a minor adjustment period in the first month for some sensitive individuals, though in my own experience with a new nylon carpet, I noticed no adverse reaction, despite being prone to allergies. Pair it with regular vacuuming and truck-mount hot steam cleaning for the best results.

Common Misconceptions When Buying Carpet

“Wool carpet is naturally hypoallergenic.” This belief exists because wool is marketed as a natural, chemical-free fibre — which sounds inherently healthier. In reality, wool sheds fine particles as it breaks down and holds moisture more than synthetic fibres, making it a food source for mould in humid Auckland homes. For allergy-prone households, this matters more than the “natural fibre” label suggests. A professional carpet dealer or cleaner should discuss fibre type against your household’s health needs, not just style.

“New carpet smell means it’s fresh and clean.” People assume a strong new-carpet smell is simply a sign of a new product doing its job. Technically, that smell comes from volatile organic compounds (VOCs) — such as formaldehyde and styrene — off-gassing from the fibres, backing, and adhesives. Emissions are highest in the first 48 to 72 hours after installation. For Auckland families with young children, pregnant occupants, or asthma sufferers, it’s worth choosing carpet labelled low-VOC or Green Label Plus certified, and ventilating the room thoroughly for several days after laying.

“Replacing carpet with hard flooring always helps allergies.” This misconception exists because carpet fibres visibly trap dust, so removing carpet feels like an obvious fix. However, hard floors let allergens settle on the surface and become airborne again with every footstep, unless they’re mopped and vacuumed consistently. Meanwhile, a well-maintained, correctly chosen carpet with regular professional hot steam cleaning can perform just as well for many households. The right approach depends on your cleaning routine, not just the flooring type.

“A thicker, higher pile always means better quality.” Buyers often assume height equals value, since a plush carpet feels more luxurious underfoot. In fact, pile height and pile twist are two separate things — twist determines durability and performance, while height is mostly a style choice. A high-pile carpet in a busy hallway will flatten and wear out faster than a well-twisted, lower-pile carpet, regardless of how premium it initially feels. For high-traffic Auckland homes, ask about twist level, not just pile depth.

“Any underlay will do, since it’s hidden anyway.” Because underlay isn’t seen once the carpet is laid, it’s easy to assume it doesn’t matter much. However, underlay grade directly affects how long your carpet lasts and how it feels underfoot. Thin or cheap underlay compresses quickly, shortens your carpet’s life, and can even damage the carpet backing over time. Match your underlay grade to your carpet grade, not your budget alone.

Expert Advice for Choosing the Right Carpet

Carpet Pile Twist

Look closely at the pile twist in the yarn. The number of twists in each pile fibre affects both performance and density. Pile density is separate from pile height — height alone tells you nothing about how the carpet will perform.

As a rule, more spring in a carpet hides footprints better. Therefore, look for a well-twisted, crimped texture rather than judging a carpet purely on how plush it looks in the showroom.

Fibre Stain Protection

Good stain-protected carpets, with soil protection and a static guard, should perform well for at least three years. Most homeowners only clean their carpets once a year, though heavy-traffic areas may need cleaning twice a year. Look for carpets with built-in stain protection, soil guard, and static protection when you buy.

Choose a Reputable Carpet Dealer

Always buy from an established, quality-focused carpet dealer with a wide range and a genuine customer service track record. Just as importantly, make sure the dealer stands behind what they sell.

Underlay and Sub-Floor Preparation

Don’t skimp on underlay — it’s not visible, but it’s essential. Cheap underlay won’t hold up under your new carpet and will shorten its life, while underlay that’s too thin can fall apart and damage the carpet itself.

Prepare your sub-floor properly before laying, too. Better-grade carpeting generally needs a better underlay class to perform as intended and protect your investment.

Professional Carpet Laying

Have your new carpet laid by a professional for the best carpet laying result. Your dealer may have an in-house installation crew, or they can recommend a trusted installer.

Choosing Colour, Texture, and Style

Colour and texture change how a room feels, and lighting conditions will shift how the carpet looks throughout the day. A soft, smooth-surfaced fibre pile suits a formal dining room, while an oriental fibre pile weave gives a more traditional or commercial look.

A more lustrous fibre brightens a room, but it will also show footprints and vacuum marks more easily. If you like that polished look, ask for a lustre fibre — if not, tell your sales rep you’d prefer a less lustrous pile.

For a textured, sculptured look, you can combine different pile heights or colours, or choose a carpet carved into the pile surface for added dimension.

High-Traffic Areas

Low-loop pile carpet is an excellent choice for high-traffic areas, such as hallways and offices. It’s highly durable, resists wear, and is easier to clean than higher-pile carpet. Chunky wool Berber carpets use a level loop pile for a popular, textured look, and their hard-wearing nature hides soiling and staining well — though few carpets outperform a good loop-pile fibre for durability.

A high-pile carpet, by contrast, isn’t well suited to heavy foot traffic. These longer fibres flatten and become harder to clean over time.

You Get What You Pay For

As with most things, a cheap carpet is usually a lower-quality carpet. It might look like a reasonable price at the time, but you may end up replacing it in 3 years instead of 25. Take your time and shop carefully.

Carpet Guarantees and Warranties

Always check what the warranty actually covers before you buy:

• Does it cover just the carpet, or the installation too?
• What voids the warranty?
• What isn’t covered?

Getting clear answers to these questions now will save you disappointment later.

Frequently Asked Questions

Is wool or synthetic carpet better for someone with asthma? For most asthma and allergy sufferers, synthetic fibres like polypropylene or solution-dyed nylon tend to perform better than wool. Wool sheds fine particles and holds moisture, which can worsen symptoms, while nonporous synthetics keep more allergens on the surface where regular vacuuming and hot steam cleaning can remove them.

How long does new carpet smell last, and is it safe? New carpet smell comes from VOCs off-gassing from the fibres, backing, and adhesives, and it’s typically strongest in the first 48 to 72 hours. Ventilating the room well for several days and choosing low-VOC or Green Label Plus certified carpet will reduce both the smell and the VOC exposure.

How often should I get my new carpet professionally cleaned? Most homes should have carpet professionally cleaned once a year, or twice a year in heavy-traffic areas. Households managing asthma or allergies often benefit from truck-mounted hot steam cleaning above 70°C every three to six months, depending on fibre type.

Is thicker carpet always better quality? No. Pile height is a style choice, while pile twist determines how well a carpet performs and wears over time. A well-twisted, lower-pile carpet will often outlast a thick, loosely twisted one in a busy hallway or living room.

Do I really need good-quality underlay, or can I save money there? Quality underlay is worth the investment. Cheap or overly thin underlay compresses quickly, shortens your carpet’s lifespan, and can even damage the carpet backing — costing you more in the long run through earlier replacement.
