Frequently asked questions
What diameter holes do you drill for ventilation?
Ventilation and extraction holes are usually drilled between Ø100 and Ø250 mm, sized to the duct or fan. We confirm the exact diameter from your system.
Can you drill through a façade and at a slight slope?
Yes. We drill through external walls and façades, including basement walls for ventilation, and where needed we angle the hole slightly downward to the outside so rainwater cannot run in. We can also drill in awkward, hard-to-reach spots.
Will dust damage the finished interior?
No. We drill with water cooling, so concrete dust is contained and the hole comes out clean and round straight away. The method is safe for rooms with finished decor, and we tidy up afterwards.
How quickly can you come, and is the survey free?
We usually reach sites across Riga and Latvia within 1–2 working days. The site visit and quote are free, and the price is based on the number of holes, the diameter and the wall thickness.
