Cost of Living & Pricing
Leiden is a historic Randstad canal city in South Holland, home to the oldest university in the Netherlands and the Leiden Bio Science Park — dense, monumental and highly sought-after. Labour runs at the Dutch norm (roughly €40–€90/hr incl. BTW depending on trade), and bilingual Dutch/English service is common.
Licensing & Regulations
The Netherlands has no national licensing for most trades, but recognised-installer schemes (InstallQ) and Gastec QA cover gas and water work, F-gas certification covers refrigerants, and an omgevingsvergunning is required for structural changes; KvK registration is standard.
Seasonal Demand
Demand in Leiden follows the Dutch maritime pattern: renovation and exterior work peak in spring and summer (April–August), while the wet climate keeps exterior paint and facade cycles tighter than drier regions. Autumn and winter storms drive emergency roofing, window and water-ingress callouts, and the energy-transition retrofit wave (heat pumps, insulation, glazing) runs year-round across the older stock.

Frequently asked questions
How long do new windows last?
Vinyl windows: 20–40 years. Wood windows: 30+ years with regular maintenance (painting/staining every 3–5 years). Fiberglass: 30–50 years. Aluminum: 20–25 years. The weakest point is the seal between panes — when it fails (foggy glass), the window needs replacement. Quality brands like Andersen, Pella, and Marvin last longer than budget options.
Are new windows worth the investment?
Yes for most homes — new windows reduce heating and cooling bills 10–25%, return 60–70% at resale, eliminate drafts and condensation, and reduce outside noise 25–50%. They're especially worth it if your current windows are single-pane, have failed seals (foggy), or don't operate properly. The payback period on energy savings alone is 8–15 years.
