Summary
[Installation company] provides a well-specified quote for dry-construction underfloor heating in Fermacell for € 2.790 incl. VAT, with a strong Google reputation and recognised professional competence. There are, however, points of attention: the Chamber of Commerce (KVK) number is missing, the liability exclusion for milling work is too broad, the text contains an unclear € 500 item that does not appear in the specification table, and the 18-month warranty period is shorter than the industry standard. Have these points clarified and recorded before signing.
The quote from [Installation company] is transparent on price and the company has an excellent reputation, but there are two risk findings you must address before signing. The most serious risk is the broad liability exclusion for drilling and milling work: ask [Installation company] to limit it and to confirm that a KLIC (utility-line) notification will be filed. In addition, the unclear € 500 item for 'cement filler' should be clarified in writing — this could mean the actual price is € 3.290 instead of € 2.790. Also resolve the missing Chamber of Commerce number and the shorter 18-month warranty period before agreeing.
