FAQs

Yes. If you find the same greenhouse for less at a legitimate US retailer, we'll do our best to match it. The comparison has to be the total price you'd actually pay, including tax, shipping and any fees, and we'll need the competitor's written quote or a link to the listing.

Please read the full Price Match Guarantee rules before you send a request. And be careful with websites whose prices look too good to be true.

Sometimes. Manufacturers update their prices, freight costs move, and we run sales and brand discounts throughout the year. The price at checkout, or on your written quote, is the price you pay. If you're watching a model, check Today's Deals or ask us whether a promotion is coming up.

As a rule, only one discount applies per order. Price matches also can't be combined with other promotions.

We only collect sales tax on orders delivered in Georgia. Other states may require you to pay use tax on your own, so check your state's rules.

Most greenhouses can be ordered directly on our website through secure checkout. For custom setups, multiple add-ons or larger projects, we can email you an itemized quote or invoice, so check your spam folder if it doesn't show up. You can also use our Request a Quote form.

We're an online store and don't have a walk-in showroom. Our greenhouses ship directly from the manufacturer's warehouse to you. We're glad to send extra photos or videos, a frame color sample when one is available, or walk you through a model over the phone. Our Photo/Video Gallery is a good place to start.

Shipping is free on most greenhouses delivered in the continental United States. The product page shows any exceptions. Delivery to Alaska, Hawaii, Puerto Rico and remote areas has to be quoted separately, and these orders usually go through a freight forwarder that you arrange.

We don't ship to Canada. For other international destinations, we can sometimes deliver to a US freight forwarder you choose. Contact us before ordering.

It depends on whether the model is in stock in the US:

• In stock: usually a few business days to process and pack, then about 5–7 business days in transit.
• Built to order or shipped from Europe: often 8–12 weeks and sometimes longer, depending on the factory and ocean freight.
• Custom colors or custom designs: typically 14–16 weeks.

If you need your greenhouse by a certain date, tell us before you order. We'll check current availability with the manufacturer and give you an honest estimate.

Yes. Before a large greenhouse leaves the warehouse, we contact you to make sure your site and foundation are ready, so it doesn't sit outside waiting. If you need delivery held until a certain week, just let us know.

Larger greenhouses come by freight truck on pallets (these can be long and heavy), and small items ship by regular parcel. After your order ships, the freight company calls you to schedule a delivery window, and an adult needs to be there to sign.

• Delivery is curbside. The driver can't carry it into your backyard or garage.
• Have two or three helpers ready. For the largest kits, a forklift or tractor makes unloading much easier.
• Tell us ahead of time about narrow roads, steep driveways, low wires or gated communities, since a full-size truck may not fit.

See our Shipping Information page for more details.

You'll get a tracking number by email when your order ships. Use our Order Tracking page or the carrier's site. Freight tracking can take up to 24 hours to update after an order ships. Once your shipment reaches the local terminal, the carrier calls to set up delivery.

Inspect every box before you sign. Count the boxes, and if anything is missing or damaged, write "DAMAGED" or the number of missing boxes on both copies of the delivery receipt, and have the driver sign both. Take photos before you open anything, then contact us within 4 days of delivery. We'll handle it with the manufacturer.

Yes. Every greenhouse needs a solid, level and square foundation. It keeps the frame true so the glass, doors and vents fit properly, and it anchors the greenhouse against wind. Common options include:

• A concrete slab or footing, which is recommended for glass greenhouses and required by many manufacturers
• A short masonry or concrete knee (pony) wall, which some models can sit on
• A pressure-treated timber or steel base frame, used for some smaller and polycarbonate models

Most kits come with an aluminum or steel base frame, but the slab or footing itself is not included. Each model's assembly manual has its exact foundation size. Try our Foundation Calculator and our foundation guide.

Choose a level, well-drained spot that gets as much sun as possible, especially in winter. Stay clear of overhanging trees and places where snow drifts or slides off a roof. Leave about 2 feet of working room around the foundation for assembly and cleaning. Call 811 to check for buried lines before digging, and think ahead about running water and power.

It depends on where you live and how big your greenhouse is. Check with your city or county building department, and with your HOA if you have one, before you order. Many of our product pages include structural engineering and permit documents that you can hand to your inspector. If you can't find them, email us and we'll send what the manufacturer has available.

No. Our greenhouses ship as complete kits with the frame, glazing, hardware and step-by-step instructions. Many brands also have assembly videos.

Many of our customers do it themselves. You'll want to be handy with a drill and a level, and you'll need at least two people, sometimes three. As a rough guide, a small or mid-size greenhouse takes about one to three days, while large and commercial models take longer. Typical tools include a tape measure, level, square, drill, screwdrivers, wrenches or sockets, a step ladder, gloves and safety glasses.

Tips: read the whole manual before you start, sort the parts first, don't install glass in high wind, and don't leave a half-glazed greenhouse overnight in bad weather.

Yes. We keep a list of assembly crews that our past customers have used, including teams that travel nationwide. These crews are independent and not affiliated with Mulberry Greenhouses, so contact a few for quotes. If you don't see someone near you, email us and we'll share any other local contacts we have.

Both work well. It depends on your goals:

• Tempered safety glass (usually 4mm) is crystal clear, looks beautiful and lasts for decades.
• Twin-wall polycarbonate (usually 4–10mm) diffuses light, insulates better than single glass and stands up well to hail and impact.
• Hybrid models pair glass walls with a polycarbonate roof, so you get the look and the strength.
• Insulated double-pane glass with a thermally broken frame is the choice for serious year-round growing in cold climates.

Most growers wish they'd gone one size bigger. Think about how you'll use it, from seed starting and overwintering to growing vegetables year-round. Plan for benches, aisles and room to grow. Our Greenhouse Size Calculator can help, or tell us how you plan to use it and we'll suggest a few models.

Yes, with the right setup. In cold climates you'll need supplemental heat, and insulated or polycarbonate models hold heat best. In warm climates, focus on ventilation and shading. Our Heater Calculator and Fan Calculator will help you size the equipment.

Many of our greenhouses come with automatic vent openers. These use a wax-filled cylinder that expands as the greenhouse warms and opens the vent, with no electricity needed. Louver windows and extra roof vents are often available as upgrades.

Yes, especially on cool mornings. Greenhouses aren't airtight, so a little condensation and the occasional drip are normal. Good airflow, venting on sunny days and a small circulation fan keep it under control.

It varies by model, size and glazing, so there isn't one answer. Many product pages include the manufacturer's structural certification with the rated snow and wind loads. Our Snow and Wind Load Calculator shows what your area typically needs.

If your area requires a higher rating than a model is certified for, ask us before you buy. Some models can be reinforced with rafter inserts or extra bracing, but not every greenhouse can be certified to every load.

Yes. Gently brush off heavy or wet snow, and never let ice build up. Snow ratings usually assume the greenhouse is closed and heated, so an unheated greenhouse needs clearing more often. Clearing the roof also lets sunlight in to warm the inside.

No. Shades and blinds are made to block summer sun and heat. For frost protection, use a greenhouse heater.

Often, yes. Several of our brands can change door placement, add extra doors or vents, or make the frame in a custom color. Custom orders take longer (usually 14–16 weeks), cost more than standard models, and can't be returned. Some designs have limits. For example, some smaller models can't move the door to the long side. Start with our Custom Greenhouses page.

Many models can. You or your contractor build the wall, then add a drop door kit so the door reaches down to the ground. Some models aren't compatible with knee walls, so ask us before you build.

We carry shelving and benches, heaters, fans, louver and shutter vents, automatic openers, shade cloths, door kits and low thresholds, tie-down kits, flooring, watering systems and grow lights. Browse our accessories, or ask which ones fit your model. Accessories are model-specific, so please confirm compatibility with us first.

Returns must be approved by us first. Each manufacturer has its own return policy, so we check with them before a return can be accepted. Here's what to expect:

• Return requests must be made within 30 days of delivery. Items must be unused, unassembled and in their original packaging.
• Approved returns have a 25% restocking fee.
• You pay the return shipping, and original shipping isn't refunded.
• Custom and made-to-order items can't be returned.
• Cancelling before your order ships has a 2.6% fee. Orders cancelled after shipping are charged the 25% fee plus shipping both ways. If you refuse an undamaged delivery, shipping both ways will be charged.

Freight for a greenhouse can cost thousands of dollars each way, so please call us at 678-408-8222 before you order if you're unsure about anything. See our Refund Policy for full details.

Just let us know. Email info@mulberrygreenhouses.com or call 678-408-8222 with your order number and a photo if you can. We'll notify the manufacturer, and they'll contact you directly with the next steps.

Every greenhouse comes with the manufacturer's limited warranty. Coverage and length vary by brand and by part (frame, glazing, accessories). Many premium aluminum greenhouses have frame warranties of 10 years or more. The warranty document is on the product page when available. Keep your order confirmation, because you'll need proof of purchase for a claim.

Very little upkeep is needed. Wash the glass or polycarbonate with mild soap and water. Avoid abrasive cleaners on polycarbonate. Clear leaves from the gutters, lubricate the sliding door tracks now and then, and re-tighten bolts after the first season. Cedar frames can be oiled to keep their color.
