Before choosing a construction company, you must be well informed.
Ask for documentation from the companies you have selected and possibly visit a house or control apartment. Also take the time you need to visit at least five reference addresses of construction sites and customers who have built with this company.
Finally, you will be able to carry out an in-depth analysis of at least three companies and request their specifications, an offer and a contract. First read the specifications carefully. Most construction companies have quality specifications, but there are also many incomplete or even incorrect specifications.
Check carefully what is included in the price offer and what is not. Who is responsible for levelling the building land or evacuating the excavated soil? Who pays for water and electricity consumption during the work? What about the security coordinator’s fee? Practical, the “Might as well know” checklist (chapter “Specifications”) will be of great help to you in this case.
Another way to avoid supplements is to thoroughly examine and discuss in advance (absolutely!) the solution chosen for the foundations and the desired finish and put everything in writing.
In any case, do so before making a firm decision about distribution, materials, execution and finishing.
The more your choices are definitively decided in advance, the fewer financial surprises you will have afterwards.
