ᐅ Window supplier does not deliver the agreed roller shutter box

Hello, we are currently in a new build project that was supposed to be delivered as a turnkey house. Unfortunately, we had major difficulties with the construction company and parted ways during the building process.

Now to the main issue. We received a quote from a window company, which we accepted. The company initially took rough measurements and then re-measured after the brickwork was done.

Our dissatisfaction started already at delivery. The windows were dragged directly over the concrete without any protection and simply placed against the masonry. Additionally, as laypersons, we noticed that the installation was improper. The windows were partially foamed only at the edge of the masonry with Styrofoam strips within the insulation layer, and no other fastenings were installed. Furthermore, all the external roller shutter boxes were 5cm (2 inches) too low in height and 10cm (4 inches) too shallow in depth, not matching the measurements from the quote. The internal and external sealing is also inadequate. We commissioned an inspector from the Association of Private Homeowners to review the defects and confirm them to the window installer again. Meanwhile, the windows are already sagging around the mid-rail area because they are not fastened to the lintel as required.

Unfortunately, we have already paid for half of the windows. Additionally, we have already sent the window installer a formal defect notification, but I do not expect the windows to be installed properly. Also, all 37 roller shutter boxes would need to be replaced.

Our lawyer says this will probably end up in court, and we will likely need to proceed with a judicial evidence preservation procedure. Moreover, a private expert report is usually rejected by the court. Of course, we cannot wait months for a court-appointed expert to inspect the matter. What options do we have, and what advice would you give us?

We are already under considerable time pressure due to delays caused by the first contractor.

Unfortunately, it is now almost standard for windows to be installed by non-professionals. Hiring trainees or inexperienced workers for the installation can save a lot on labor costs. Skilled professionals are so scarce that this was a major reason for my decision to leave the window industry.

How did things turn out for you?
We had trouble elsewhere. That’s why I asked about the termination above, which situation you had, and about the construction manager. Did you hire a new one? If not, be prepared for a work stoppage; you will get a deadline from the building authority to appoint a new construction manager.

Do you have an independent construction consultant?

Did you have the termination handled through a lawyer?

With the windows, it was “only” the wrong panes. Because of the energy subsidy program (KfW), we had to recalculate whether this could be compensated elsewhere. We ended up doing that with the roof windows and had to pay significantly more.

We left the window installer alone; he was just a poor subcontractor and nothing could have been gained from him. We followed our lawyer’s advice and got tips from other homeowners to avoid unnecessary purchases at first and to expect unplanned additional expenses.

How can it be ensured nowadays that windows are still installed properly?

Hello, I always thought I was the only one who messed up like this. Among other things, we had problems with the windows. The general contractor ordered them from Poland and had them installed by his own people, who are anything but specialists. They installed and “sealed” 28 windows in 2 days. The windows themselves, including the external roller shutters, are fine—nothing to complain about. Except that the patio doors are 5cm (2 inches) too short. Well, after the first complaint about the sealing, sealing tapes were stuffed from the outside between the reveal and the frame on the already installed windows. After the second complaint, everything was scraped out again and completely sprayed with foam from inside and outside. Complained again. Final deadline was set, and a three-layer sealing was demanded. We begged a local window fitter to take on the work, but he was very reluctant because of the warranty issues for the windows and shutters, although he eventually did it.

Costs for windows: €18,000; installation and sealing #1: supposedly €10,000; sealing #2: €3,000; sealing #3: €5,000; and the 4th and final one was just under €7,000. The 4th sealing also took 7 working days with 3 workers.

It’s difficult. There is no official standard (DIN) for window installation, only guidelines. You would already have to make sure the construction contract states something like: Installation and sealing according to the guidelines of the Institute for Window Technology Rosenheim or sealing with three-layer sealing tape. But who has dealt with that at the time?

If I were to build again (I'm still in the middle of it): Check reference projects during installation!

Our windows were also installed only "suboptimally" and need to be reworked (doors are excellent, a different supplier was responsible). We expect feedback from the window manufacturer next week.

You can’t see it anymore once the plaster is applied; then all the poor workmanship is hidden. They tried the same with us, but fortunately I had photos. You either notice it after 2 years by mold or better yet beforehand with a blower door test.
