Professional installation service: what is included?

A professional installation service assembles the delivered structure as agreed. Foundations, consents, connections, excavation and extra services are not automatically included. This guide outlines the usual scope, site preparation and key checks before you proceed.

Professional installation at a glance

A professional installation service assembles a delivered structure correctly using the intended instructions. What matters is not the word “installation”, but the confirmed scope. For a greenhouse, pergola or outdoor sauna, foundations, unloading, electrical work, sealing, accessory fitting and site clearance may be arranged differently.

Before ordering, consider three separate areas: product delivery, site preparation and installation itself. Find guidance on ordering and receiving goods under Shopping and delivery. For greenhouses, you can also enquire about a dedicated greenhouse installation service .

Project area	Typical responsibility	Confirm before ordering
Product and configuration	Customer and seller	Model, orientation, options and accessories
Base and site	Usually the customer	Foundation, level, access and working space
Installation	Appointed installation team	Components and tasks included exactly
Connections and consents	Separate trades or the owner, depending on project	Local requirements and interfaces
Handover	Customer and installation team	Inspection, outstanding items and records

What professional installation usually means

Professional installation normally means qualified installers assemble, align and secure the structure named in the order from the delivered components, within the agreed scope. The selected product, installation instructions, prepared site and written quotation provide the basis.

The service is not a blanket undertaking of the whole building project. An installation team can work only on a suitable, accessible site made available on time. If a foundation is unfinished, the surface falls outside agreed tolerances, or components cannot be safely moved to the location, proper installation may not be possible.

Product reviews can help with selection, but they do not replace assessment of the individual project scope. The greenhouse reviews page offers further guidance. The documents confirmed for the specific order always prevail.

Tasks that may be part of installation

Depending on the quotation, installation may include sorting delivered components, building the base frame, fitting structural profiles, placing specified wall and roof elements, and installing included doors, windows or controls. Fixing to a prepared base may also be included where the base, fixing method and responsibility have been clearly agreed in advance.

• Check the supplied components for obvious discrepancies that could affect installation
• Assemble the main structure specified in the order
• Align and connect the structure according to the installation instructions
• Fit expressly included original accessories
• Function-check moving mechanical components
• Carry out a joint visual inspection at handover

For greenhouses, tasks depend in part on glazing type, roof design and accessories. The guide to polycarbonate for greenhouses covers technical aspects of sheet materials. For larger or more architectural installations, such as an orangery, interface planning should begin particularly early. See the orangery greenhouse guide.

What is not automatically included

Services beyond product assembly must be agreed expressly. Creating a foundation, in particular, is not automatically part of an installation service. The same applies to demolition, excavation, drainage, paving, wall openings, roof connections to existing buildings or adapting unsuitable existing surfaces.

• Planning and construction of foundations or slabs
• Excavation, ground levelling, tree removal and root clearance
• Applying for or checking official consents
• Structural assessment of existing patios, roofs or timber decks
• Electrical, water, wastewater, heating and network connections
• Additional cranes, lifting equipment or specialist transport
• Installation of unconfirmed third-party products
• Landscaping, interior furnishing, planting beds or sauna accessories outside the order
• Disposal of old structures, excavated material or third-party packaging

For pergolas, plan the foundation separately. The pergola foundation guide explains the essentials. In New Zealand, building-consent exemptions and resource-consent requirements are separate questions. Whether a structure needs approval depends on its actual design and use, site, foundations, services, boundary conditions and district plan. The consent guide for greenhouses and pergolas provides initial guidance; check the current project-specific requirements with the relevant council before work begins.

Installation sequence and timing

1. Choose the right product and configuration

Dimensions, door positions, roof design, opening elements, attached side and accessories affect the site and installation. Measure the available area at several points before ordering. Doors, roof overhangs, maintenance access and intended use all need space. See the greenhouses and conservatories section for an overview of designs.

2. Request and review the installation scope

The quotation should identify the product, site, included accessories and visible exclusions. Check whether fixing, unloading, packaging disposal and travel are covered. Confirm verbal expectations in writing before approval. Contact customer service or the contact page with questions.

3. Check local project requirements

Before starting, check boundary conditions, district-plan rules, service routes, drainage and any required approvals. Rental properties, unit-title homes or shared areas may require additional permission. Confirm the applicable requirements for the property and project with the relevant local authority or other responsible party.

4. Prepare a sound base and work site

The base must suit the specific product, meet its dimensions, be level and be ready in time. For fresh concrete, allow for the required construction and curing conditions. The installation team should not be obstructed by earthworks, paving or foundation work by other trades.

5. Coordinate delivery and storage of components

Provide a safe, dry and accessible storage area. Do not place long profiles, glass or panels where they block accessways or may be damaged. Inspect the delivery using the supplied guidance and report visible issues promptly. For New Zealand deliveries, see the delivery information and confirm the delivery terms, importer, GST and clearance responsibilities before ordering.

6. Carry out a final readiness check

Shortly before the appointment, recheck access, working space, base and component stock. Tell the installation team about underground services, delicate surfaces, restricted access and other trades. Keep pets and uninvolved people away from the work area.

7. Install the structure

Installers assemble the agreed components in a technically appropriate order. Keep the area clear while work is underway. Last-minute changes to location or configuration can require further checks, additional parts or an amended order, and should not be improvised during installation.

8. Inspect the work and hand over

At handover, inspect the installed areas together. Test doors, windows, louvres and other moving parts within their intended function. Record visible outstanding items clearly. Keep order documents, installation information and guarantee information.

Site-readiness checklist

• The final model, accessories and orientation are confirmed.
• The installation location is clearly marked and matches the plan.
• Local requirements and any necessary approvals have been checked.
• The foundation or installation surface is finished, accessible and suitable.
• Underground and concealed services are known and marked.
• Access, gate widths, steps, slopes and transport routes have been advised.
• Delivered components are stored safely and close enough to the installation site.
• Adequate work space is clear of furniture, plants and building materials.
• Other trades working in parallel will not obstruct installation.
• An authorised contact person can be reached.
• Electrical work should be handled by a licensed electrician, and water connections by an appropriately qualified tradesperson.
• Special conditions were reported in writing before the appointment.

If an item cannot be met, do not leave it unresolved until installation day. Early coordination allows technical assessment and helps avoid unnecessary travel or interruptions.

Product type changes the installation plan

Greenhouse: Glazing, vents, doors, gutters and interior accessories determine the installation steps. Consider later use when choosing the position. The guide to greenhouse temperature and humidity offers climate and ventilation advice.

Pergola: For a wall-mounted installation, assess the existing façade, connection heights and suitable fixing options as well. The comparison wall-mounted or freestanding pergola helps with the initial choice. Check size and space requirements using the pergola size guide . The pages on bioclimatic or classic pergolas and is a bioclimatic pergola worthwhile?

Outdoor sauna: Alongside a load-bearing base, plan the transport route, ventilation, drainage and interfaces with technical equipment. Models such as the Elma S outdoor sauna, the HC150 barrel sauna or the HCF 225 barrel sauna may have different planning requirements. The product documentation for the selected model is therefore decisive. Find more models under sauna. Ask a licensed electrician to assess any heater or electrical supply, including installation, protection, equipment suitability and certification requirements.

Changes, delays and work outside the quotation

An installation quotation is based on known conditions. If the model, site, access or base changes, check whether the price, materials and timing still apply. Additional work should begin only after written confirmation.

Typical causes of delay include an unfinished installation surface, missing components, blocked access, unreported steps or narrow points, and building work happening at the same time. Conditions that prevent safe transport or assembly may also require a pause. The response depends on the order and circumstances at the site.

Principle: a change affecting the structure, fixing, safety or working time is not a minor adjustment. It requires technical and commercial clarification.

After installation: use, care and maintenance

After handover, use the structure only as intended. Keep doors, tracks, drainage paths and moving elements clean. Regularly inspect visible connections, seals and components for unusual changes. Unauthorised drilling, additions or alterations can affect the structure.

For aluminium structures, the guide to caring for your aluminium greenhouse provides practical guidance. For greenhouses, the gardening fit-out begins after structural handover and is not part of installation. For ideas, see the guide to growing lettuce in a greenhouse.

How to assess the service before buying

A reliable quotation does more than state a price. It defines the service clearly and identifies prerequisites. Do not compare quotations solely by the total amount.

1. Product scope: Is the exact model and its accessories named?
2. Site scope: Have the address, access and installation location been considered?
3. Preparatory work: Are the foundation and site readiness clearly described?
4. Interfaces: Is responsibility for fixing, connections and sealing clear?
5. Exclusions: Are excluded tasks identifiable?
6. Handover: Will there be a joint inspection and a contact person?

Frequently asked questions

Is the foundation included in professional installation?

Usually not automatically. Building a foundation is a separate construction service. It is included only when expressly described in the quotation. Dimensions, construction and suitability must match the chosen product and local ground conditions.

Does the installation service include consents?

Checking and obtaining official or private approvals is usually the owner’s responsibility unless agreed otherwise. New Zealand building-consent exemptions do not remove Building Code duties or possible district-plan resource-consent requirements. Confirm the current local rules for the specific property and project.

Can installation be carried out on an existing patio or timber deck?

Possibly, but not without a suitability assessment. Load capacity, construction, level, drainage and fixing options must suit the product. The installation team does not replace a structural assessment of an existing structure.

Are electrical and water connections included?

Not automatically. These are separate interfaces and must be expressly agreed and completed to applicable local requirements. Plan necessary work with appropriately qualified professionals. WorkSafe’s homeowner electrical pathway does not extend to saunas.

Will the team install accessories from other suppliers?

Only where this has been assessed and confirmed in writing beforehand. Third-party accessories may need different fixings or be incompatible with the structure. Deciding this on installation day is unsuitable.

Can I change the greenhouse position on installation day?

A seemingly small move can affect the foundation, orientation, access, boundaries and service routes. Assess changes before work starts. If the new location is not prepared, installation may need to be postponed or quoted again.

How long does professional installation take?

Timing depends on product type, configuration, accessories, access, site condition and scope of work. A reliable estimate is possible only once these details are known. A non-binding standard figure is not enough for scheduling.

What happens if the site is not ready?

The installation team checks whether work can proceed safely and correctly. Where there are significant discrepancies, installation may be paused, partly completed or rescheduled. Any resulting consequences depend on the agreed order.

Do I need to be present during installation?

Continuous attendance is not always necessary. However, an authorised person should be reachable and able to complete handover. Access, location and special requests must be clearly agreed beforehand.

Are greenhouse interior layout and planting included?

No, unless expressly agreed as an additional service. Beds, tables, irrigation, growing medium and planting relate to later use, not normal structural installation.

Is site cleaning included?

Normal work-area tidiness differs from full site cleaning and disposal. The quotation should state whether product packaging will be removed. Third-party waste, excavated material and old components are normally excluded.

Who do I contact about a problem after handover?

Document the relevant area with a clear description and suitable photos. Keep order and installation details available, then contact the responsible team through Bloomcabin contact options . Do not make changes before clarification that could make assessment harder.

Final principle on scope

Professional installation is easiest to plan when product, site and responsibilities fit together. Do not rely on a general service label. The written quotation, confirmed configuration, installation-ready site and clearly defined interfaces are what matter.

Ask about anything needed for the project that is not expressly listed as included before approval. This simple rule protects the customer and installation team from misunderstandings and supports an orderly build and traceable handover.
