ᐅ Roof windows – Costs with and without installation

Hello,

we are considering installing two additional skylights in the attic, which is currently not insulated.

I found one from the market leader, a pivot window measuring 78 x 118 cm (31 x 46 inches), costing about €440 at the local large hardware store.
Plus the flashing kit, the total comes to around €510.

I’ve now called two contractors, and both mention roughly "€1200 net" or "around €1500" for supply and installation.

I would have expected installing skylights to take about 4 hours? Hourly rate €60? That would total roughly €750.

Where am I mistaken? Have I forgotten something?

Best regards,
Simon

Building supply store materials are rarely used for installations. Additionally, profit is also made on purchasing.

It's similar to my car repair shop. If I buy new tires online, the installation costs $40 per wheel. If he orders them through his dealer, it costs $25.

- Profit/loss
- Ordering, coordinating, and inspecting the installation site also cost money
- "Non-productive" employees still need to be paid
- The workload situation in the construction industry

Also, the question is whether it can really be done within 4 hours. Does the roof need to be stripped and re-covered? Do rafters and beams need to be added? (I assume so.) All of this takes a lot of time.
Depending on the scope of work, the price is reasonable.
Installing only the window, without having to do anything else, should cost around €1000-1300.

Hardware store products → Products from the market leader. Therefore, I assume they get even better prices. Or do they all calculate based on the recommended retail prices?

I would have now included profit, overhead costs, and ordering in the hourly rate; is €60 per hour (about $64) too low as an assumption?

The roof does not need to be removed, only an opening created. Someone mentioned that would be around €120 (about $128). No rafters or beams will be added; the window fits between them.

€1000 (about $1065) would still be within the range of my rough estimate.

In 2017, an Elux unit was installed here for 850 plus tax, so it cost just over 1000. Even if the business is small, it brings in more work... that’s why the window won’t end up on the invoice for 510, but rather for 810, bet?
