How we work

What to send us so the quotation is accurate the first time

Most of the back and forth on a quotation is us asking for something you could have sent in the first message.

What to send us so the quotation is accurate the first time

Get a quotation for the whole outdoor project

You can ask about a single service or roofing, decking and blinds together. Use the same scope when comparing quotations so differences in materials, supporting work or accessories do not disappear behind a single total.

On a small screen, scroll the table sideways to compare each option.

Compare outdoor zip blind installers on the same scope

For a Singapore balcony, compare the named blind system, each measured opening, fabric, operation, fixing work and aftercare before comparing the total. Exterior Design supplies and installs ZipNice. You can ask us about blinds for one balcony without adding a roof or decking.

If you are considering an alternative to Ziptrak, ask for ZipNice by name in our quotation. Ziptrak is a separate brand; a quote described only as “zip blinds” does not identify either system. Compare the actual proposed components and installation rather than assuming different brands have the same performance or warranty. Our Ziptrak and ZipNice comparison worksheet sets two quotations side by side.

On a small screen, scroll the table sideways to compare each item.

A checklist for comparing zip blind quotations
CompareAsk each installerWhat you can check with Exterior Design
Named system and openingsWhich system and model are quoted? Are the width, drop and number of bays listed separately?We supply and install ZipNice. Send an overall balcony photo and a photo of each opening; rough dimensions help start the discussion.
Fabric and viewWhat is the fabric code, colour and openness? Compare a sample in the light conditions where you will use it.Our ZipNice options include 1% openness and 0% blackout. See the fabric choices and specifications.
Operation and electrical workIs it manual or motorised? If motorised, which motor, controls and electrical work are included?Both operation types are available. Watch an installed blind moving. Confirm the components for your own quotation.
Fixings and existing coverWhat will the headbox and tracks fix to? Are uneven returns, the floor, access and any supporting work included?Show the top fixing area, side returns and floor. A blind screens the side of a space; an uncovered patio may need overhead shelter considered separately.
Weather limitsWhich test or operating guidance applies to the quoted system and panel size? What should you do during strong winds?Zip blinds are fabric screens, not sealed windows. Some spray can enter during heavy rain. Ask for operating precautions for the selected installation.
Installation evidenceCan you see installed work with a similar opening layout and observe the system operating?Browse our blind installation photographs and the operating video. Photographs show the layout; they do not establish a tested wind rating or a warranty.
Full price and aftercareAre installation, access, electrical work, removal where needed and applicable tax clear? Which fabric, motor, frame, labour and servicing items does the written warranty cover?We confirm the scope before the final quotation. Request itemised inclusions and exclusions, written coverage and any servicing charges for the proposed system.

Match the decision to the space

Prepare a blinds quotation brief → Include the openings, photographs and operation you prefer. Final dimensions and installation details are confirmed before the work is agreed.

Four photographs

Standing inside the space looking out. This shows us the opening, the sightline you are protecting and what is already overhead.

Standing outside looking back at the space. This shows the elevation, the fixing points and what the finished system has to sit against.

Straight up at whatever is overhead. Slab, existing roof, open sky. This decides whether a blind needs a roof first.

The edges. Where the space stops: the parapet, the wall return, the glazing threshold. Almost every awkward detail on a job lives at an edge.

Three measurements

Width of each opening, corner to corner.

Height from floor to whatever the system fixes to.

Depth of the space from the building out.

A tape measure and rough numbers are fine. We measure properly on site before anything is made; these are for telling you a realistic range before either of us spends a site visit on it.

Three answers

What is the space unusable for, and when. Sun at four in the afternoon and rain in a squall are different problems with different answers.

Landed or condominium. If it is a condominium, check what your estate actually requires before installation; the condominium checks below show what to ask.

Do you need to keep the view. On blinds this decides the fabric openness. It is the specification people most often discover too late.

Condominium checks before installation

What to check depends on your estate and on what you are installing: a blind, a balcony screen or a new overhead cover. These are general rules, checked on 31 October 2026. They do not confirm that a product, supplier or particular installation is approved.

External changes. Exterior walls can be common property. BCA condo-owner guidance says altering external building features, or adding something that affects the building’s appearance, needs agreement from your estate’s management corporation (MCST) and any relevant agency approvals. Check your estate’s restrictions before work starts.

Balcony blinds and screens. URA balcony guidance says balcony blinds can be allowed without URA planning permission, and sets separate criteria for balcony screens, including opening or retracting fully and allowing natural airflow even when closed. Proposals should follow the MCST’s design guidelines. Ask which approved design applies to the system and fabric you are considering.

New overhead cover. URA open-sided-cover notes say no URA submission is required to install open-sided covers over balconies, private enclosed spaces or private roof terraces in strata residential developments. Owners must still obtain MCST consent and meet any applicable building-control and fire-safety requirements. The note is limited to those covers, areas and developments.

Ask your management which fabric, finish and fixing requirements and which permissions apply to your unit, and send any written requirements with your quotation brief.

What you get back

A recommendation of which system we would actually put there, including when that is the cheaper one or none of ours.

An initial discussion of scope and cost where the photographs and information are sufficient. The measured installation details are confirmed before the final work is agreed.

A written quotation naming the material, the finish, the frame and the warranty terms. We do not publish numbers we cannot stand behind, so anything not yet confirmed is written as pending rather than guessed.

Questions

Questions we get on this one.

If yours is not here, send it on WhatsApp. We answer with what we know and say so when we do not.

Do I need a site visit before getting a price?
Photos and rough dimensions can help us discuss an initial scope and, where the information is sufficient, an indicative cost. A final quotation depends on the selected systems and confirmed site details.
Will you tell me if I do not need what I asked for?
Yes. Recommending the cheaper system, or none of ours, costs us one job and saves the relationship. It is the whole reason the fit checks on our product pages list where each system is the wrong choice.
How do I send the photos?
WhatsApp is fastest, on +65 8129 9381. Send the four photographs in one message with the measurements and we will come back with a recommendation.
Can I get one quotation for roofing, decking and blinds?
Yes. Include all the services you want considered and tell us which existing elements you want to retain. The written scope should identify the chosen systems, materials and installation work for each part.
Why can quotations for the same-sized space differ?
The quoted board, panel, fabric, frame, motor, fixing work, access and finishing may differ even when the area is similar. Compare the itemised scope, inclusions, exclusions and written terms before comparing the totals.

One photo is all it takes.

Tell us your property type and rough dimensions and we will tell you which system actually suits the space, and what it should cost.
