Question 1

Is this a quote?

Accepted Answer

No. It's an indicative online estimate. Only a company, usually after a visit, can provide a binding priced quote.

Question 2

How is the price calculated?

Accepted Answer

Each answer triggers cost rules: quantity (m², metres, units), materials, quality level, preparation work, region and building age. Base prices come from sourced, dated Swiss market references.

Question 3

Why a range instead of a single price?

Accepted Answer

Real prices depend on the company, hidden building conditions and finishes. The range honestly reflects that uncertainty.

Question 4

Why is the range sometimes wide?

Accepted Answer

The less precise information we have, the wider the range and the lower the confidence. Answering "I don't know" is allowed but widens the result.

Question 5

Is VAT included?

Accepted Answer

Amounts are shown in CHF including VAT.

Question 6

Why ask for the postcode and construction period?

Accepted Answer

Prices vary by region, and older buildings often need extra work (code compliance, asbestos, uneven surfaces).

Question 7

Can I estimate several jobs?

Accepted Answer

Yes, by running one estimate per type of work, which keeps each calculation clear.

Question 8

Are there grants for my project?

Accepted Answer

Energy works (insulation, windows, heat pumps, solar) may qualify for the Buildings Programme and cantonal or municipal grants. Our city pages list known grants with sources.

Question 9

Must I apply before starting work?

Accepted Answer

In most cantons yes: the application must be filed and approved before work begins.

Question 10

Do I need a building permit?

Accepted Answer

It depends on the work and the municipality. Facades, roofs, solar, outdoor heat pumps or listed buildings often require a notice or permit.

Question 11

Are renovation costs tax-deductible?

Accepted Answer

Maintenance and energy-saving investments are generally deductible from taxable income; rules vary by canton.

Question 12

How are companies selected?

Accepted Answer

Active companies from the commercial register near your postcode whose website mentions the relevant trade. They are neither partners nor official recommendations.

Question 13

How many quotes should I get?

Accepted Answer

Ideally three comparable quotes based on the same description of works.

Question 14
