Top! Very professional, excellent planning and execution. And very responsive whenever something needs to get fixed. We are extremely happy with our "dakopbouw" and recommended them to many people already. Great people too.

Very satisfied with Slappendel Bouw! Work: two-bedroom extension approximately 30 m² + all-round insulation + roof insulation / new facade. Timeframe: 95% completed in 6 weeks and only 4 to 5 days open, top performance. We were even able to stay. Reliable, friendly, knowledgeable, neat, and cheerful! + A shed was installed a year earlier, everything was to our satisfaction.

Top-quality workmanship! Our extension was installed exactly to our specifications. They were very helpful and provided personalized advice. Everything was communicated in a friendly manner. We were kept well-informed throughout the entire process, and everything went according to plan. Friendly and helpful craftsmen! Highly recommended! Thanks, Daan and your team, for your excellent work!

Very satisfied! Had two dormers installed. They were reinforced. After a few years, the corner profile became loose. Slappendel ultimately replaced what needed to be done without any problems. I would recommend them.
