When is a mounting partner a better fit than own fitters?

At Dietsche MontageProfis, we repeatedly see the same thinking error in practice: many companies calculate headcount first, not capacity utilization. This is where the decision tips, because a team that is fully loaded in January can be too small in midsummer. Contrary to the assumption, the question is not first how many fitters you want, but what load you can really carry over the year.

When is a mounting partner better suited than own fitters?

A mounting partner is particularly suitable when orders vary strongly over the year, when geographic reach is more important than proximity to your own plant, or when additional capacity is needed on a point-by-point basis. This typically applies to manufacturers who deliver nationwide but do not want to maintain equally large installation teams at every location. Also when several construction sites start at short notice, external installation is often the cleaner solution.

Which criteria should you check in this order?

1. Check base load over twelve months, because it covers fixed costs.
2. Evaluate order fluctuations and peaks, so you do not optimize for the wrong month.
3. Calculate geographic distance, because around 50 km of travel time often also entails overnight stays.
4. Clarify required qualifications, e.g., aerial platforms, forklift or fire protection.
5. Assess product proximity and liability, especially with delicate connections, tight deadlines, and clear responsibility on site.

Hire as many fitters as you can sustain in January; everything beyond that you should get from the partner.

From my experience, distance is often underestimated. An extra trip not only costs travel but also travel time, a half to a full lost installation day, and for larger distances an overnight stay. That is why a seemingly small delay can quickly become expensive if using an external team.

From what load is permanent employment worthwhile?

The concrete threshold depends on the product and region, but as a practical rule: own fitters only pay off cleanly when base load is stable over twelve months. A kitchen manufacturer with around 300 kitchens per year would in our example come to about four fitters as base load. In peak months, eight to ten are needed, and this is where the difference between base load and peak becomes evident.

What hardly anyone has on the radar: not the peak alone makes the model expensive, but the wrong distribution of the load. If you staff for the peak, you pay too much in the weaker months. If you staff only the base load, you push deadlines and pull subcontracts like tilers, painters, final cleaning and handover of keys later.

For whom are own fitters the better choice?

Own fitters are especially worthwhile for carpentry shops and manufacturers who require a high degree of product knowledge and whose construction sites are closely tied to the plant location. This is often the case with interior finishing, kitchen installation, door installation and similar series with a lot of repetition. The more closely product, planning and installation mesh, the more a fixed team pays off.

• Base load is stable over twelve months.
• Installations are usually within short travel distance.
• Products are complex and repeat often.
• Liability and quality assurance should remain internal.

When is an external partner clearly the better solution?

A mounting partner is the better choice when workload fluctuates strongly over the year, when nationwide coverage is required, or when many fitters are needed at short notice. At Dietsche MontageProfis we work nationwide with around 400 fitters at four locations, precisely for such cases. This is especially helpful when a project needs a lot of personnel in a short time or when specific qualifications are missing on site.

In our experience, the partner is not a stopgap but often the more economically clean structure. A concrete peak case is, for example, a store renovation overnight or a multi-family house with 40 kitchens in two weeks. In such situations, speed is more important than an internal team designed for years.

Where is the biggest mistake in the decision?

The most expensive mistake is a second trip. It costs travel, travel time and half to a full lost installation day; with distance, an overnight stay is often added. It gets even trickier if a qualification proof is missing, because then the team may stand still or the construction management may deny access.

Frequently asked questions

For carpentry shops, kitchen, door and window manufacturers, the order of operations is therefore clear: first calculate base load and fluctuations, then check distance and qualifications, finally determine liability and contract form. Those who follow this sequence cleanly avoid costly misplacements and do not push jobs to the wrong reason.
