Henk (and his wife) installed a new Velux window for us, complete with a sunshade, blackout blind, and mosquito screen (all Velux), as well as a screen for an existing Velux window. Very satisfied with the result and the entire process. The price was good, and everything was cleaned up very neatly (and the old window was removed). Highly recommended! Last year (in our previous home), they also installed three Velux windows and removed the old ones. That's why we hired them again this time.

Recently, Henk and his colleague Geert installed a skylight in our bathroom. They did a great job and delivered top-notch work; these professionals are highly recommended. Thanks, gentlemen.

Henk en Geert samen 8 Velux dakramen bij ons geplaatst. Het was mooi weer om dat te doen, sneeuw, wind en regen :-) We zijn zeer tevreden er wordt goed overlegt en Henk heeft echt de kennis van dakramen. Beide zijn zeer toegankelijk en ze werken netjes.

5-star rating for the 5-star workmanship; new Velux skylights installed. Henk is not only knowledgeable, but also hardworking, tidy, friendly, and honest. He also responds quickly, keeps you informed when needed, and thinks along with you. I'm extremely satisfied! Groningen, 2 Velux skylights
