Everything went according to the plan. We are happy with the quality of the dormer. I would definitely suggest ABM Tilburg if you are considering a dormer.

These are true professionals who oversee everything down to the last detail. From design to construction of the dormer window and the final installation, everything was perfectly organized and executed. Communication with everyone involved was also excellent. In all the renovation work we've done in recent years, they've been head and shoulders above the rest in terms of service! Thanks to the entire team.

We had a dormer window installed at the rear of our house, spanning the entire width, through ABM. During the measurements, we received expert advice and they were truly cooperative. The quote needed to be adjusted, which was no problem at all. ABM responded promptly. On delivery day, the work was carried out efficiently. Two pipes on the roof had to be removed and a roof tile was to be placed in their place. This was done perfectly. When the dormer window was installed, there was still a pipe on the other side of the roof, but it was now crooked. A worker moved the pipe higher up on the roof and replaced it with a roof tile. This was effortless and there were no additional costs. The dormer window was installed in just under 4.5 hours, and the workers left the attic neat and tidy. We are very satisfied and highly recommend ABM Dormers. The insect screens were also neatly installed.

From attic to full-fledged room! After reading the great reviews here, I contacted ABM in May of this year. We were able to quickly schedule an appointment for Jan's advice and measurements for the dormer. Because we had some doubts about our roof structure, we hired a structural engineer to make the necessary calculations. This meant it took a little longer than expected, but patience is rewarded. The structure was modified (at our request) and the dormer installed. The installation and structural modifications went incredibly quickly and smoothly. It was completed in just one day by hard workers Stefan and Wesley. All the debris was removed through the roof, and there was no mess in the house—perfect! It was also great that Jan came by several times on the day of installation to discuss everything. Last but not least, the price. Incredibly reasonable! We are very satisfied with the price-quality ratio. In these times when prices are skyrocketing, this is certainly important! Thanks, guys!
