What happens at a survey, and why a fixed price needs one

The calculator gives you a budget, not a price

The budget calculator on the homepage does one thing: it takes a floor area and a specification level and applies published average rates to them. That is genuinely useful. If you are deciding whether a shell in Sliema is within reach, or working out whether to put a deposit down on something larger, an average is the right tool — it tells you the order of magnitude and it does it in thirty seconds.

What it cannot do is commit anyone to a number. An average rate is, by definition, built from properties that are not yours. It does not know that your ceilings are 3.4 metres and every wall finish costs more as a result, or that the previous owner's shell was left with services stubbed in the wrong corner, or that your block has a lift too small for a bath and a stairwell that turns twice.

The survey is the step that replaces the average with the actual property. That is the whole of it. Not a sales visit, not a design consultation — a measured inspection whose output is a price that can be fixed because it is based on something real.

What is actually being measured

Measurement comes first because almost every trade is quantified off it. A tape and a laser go round the whole property and produce:

• Floor areas, room by room, not the gross area on the deed. Deed areas often include structure, shafts and shared elements you will never tile.
• Wall areas and ceiling heights. Malta's older stock and many new shells have generous heights, which is pleasant to live in and quietly expensive to plaster, paint and heat or cool.
• Aperture openings — every door and window reveal, measured as a hole in a wall rather than as a product, because what fits is decided by the opening.
• Level differences. Shells are frequently poured with steps and falls that the finished floor has to absorb, resolve or make a feature of.
• Wet area extents, so waterproofing and tiling are priced against the surfaces that exist rather than a nominal bathroom.

Squareness and plumb get checked at the same time. A room that is 40 mm out over its length is not a problem in itself; it becomes one when a fitted kitchen or a large-format tile has to meet it.

What is being looked at

Alongside the measuring, the survey reads the condition and the services.

Substrates. What is under the finish decides the finish. Bare blockwork, an existing plaster of unknown quality, a slab with laitance on it and a screed that sounds hollow when tapped are four different starting points with four different costs, and only one of them is what the calculator assumed.

Services as built, not as drawn. Where the water enters, where the drainage exits and at what level, where the meter and consumer unit sit, what the incoming supply can carry, and whether soil pipe runs constrain where a bathroom can actually go. Moving a soil connection is one of the reliably expensive decisions in a finishing project, and it is usually discovered rather than planned.

Moisture and the envelope. Roof and terrace waterproofing, parapet junctions, and any sign that water has been getting in. Damp found before the plastering is an item on a schedule; damp found after it is a rework.

Access and logistics. How material gets in and waste gets out. Street width, parking and loading restrictions, staircase width and turns, lift dimensions and whether the lift may be used for materials at all, and whether hoisting from the street or a balcony is required. In Gozo, every delivery and every trade visit crosses on the ferry, which changes how work is sequenced rather than whether it can be done.

What the building permits. If it is an apartment, the condominium deed and rules bind the works — hours, use of common parts, hoisting, anything touching the facade or the roof. Separately, the Planning Authority governs permits, and whether your intended works need one has to be established before a price can be fixed rather than after.

Scope across trades. The services page lists 22 trades and project types, and part of the survey is establishing which of them your property actually calls for and in what order. A shell that needs partitioning, screeds, first-fix and full aperture supply is a different project from one where the developer left plastered walls and a screed down.

What moves the number, and in which direction

Honestly: both ways.

Nobody can tell you in advance which side your property lands on, and anyone who tells you the survey will bring the price down is selling rather than surveying. What the survey guarantees is that the figure is about your building.

Why the fixed price depends on it

A fixed price transfers risk. Whoever gives it is agreeing to absorb the difference between what was assumed and what is found, which is only a reasonable thing to agree to once someone has looked. Without a survey, the only defensible options are a range, a price with a long list of exclusions, or a number that will be revised the first time a wall is opened. Buyers arriving from the UK or elsewhere in the EU are often used to a market where the property is sold finished and the unknowns are structural rather than everything from the plaster inwards; in Malta, where shell form is the normal way property changes hands, the unknowns are the project.

So the sequence is: use the calculator to find out whether the project is plausible and roughly what scale of money is involved. Then have the property surveyed to find out what it costs. The first is an average with your dimensions typed into it. The second is your building, measured.
