What you can expect from ProMont Alu.

We are ProMont Alu from Krefeld. We build your aluminium garden room with our own team. After the free site survey you receive a fixed price and six written promises.

What you should know beforehand

We are not the cheapest. Instead you get a team that stays the same from the site survey to the installation, a fixed price that is written into the contract, and a contact person who answers the phone. If the lowest price matters most to you, we are probably not the right choice. If you want a room you would never want to be without, we would be glad to talk to you both.

Six promises, in writing in the contract

What we promise you is set out in black and white in your contract. For each promise we tell you why it exists.

  1. 1On schedule: installation in 5 working daysNobody should have a building site in their garden for longer than necessary, so we plan for a date to stay a date.Or the installation is free. We count the total of installation days, not consecutive days (e.g. the roof first, awnings later after delivery). Exceptions: weather, delays on the client side, defective parts, force majeure (AGB § 8).
  2. 2Watertightness: 5 yearsA roof that drips is not a room. That is why we promise you the repair and the deadline in writing.Water through the roof, gutter joint or silicone seal: free repair within 72 hours of your report. Exceptions under AGB § 17 (blocked gutters, uneven wall after our notice, third-party damage, lack of maintenance).
  3. 3Fixed price after the site surveyYou should know the price before we build, and it stays that way.Not a cent more. If we miscalculate, we bear the difference. Valid for 30 days from the offer.
  4. 410 years on the structureYour garden room should still stand safely in ten years.Load-bearing aluminium structure free from material and manufacturing defects. Free repair or replacement (AGB § 17 (4)).
  5. 55-year colour guaranteeYour garden room should look the same years later as on the day of handover.Powder coating without visible colour change under normal care. Manufacturer’s guarantee; 2 years on the coast and by swimming pools.
  6. 6Your personal project managerAfter you sign, you should never be left on your own. You know whom to call.One person, one number, for the entire guarantee period. Reply usually within 24 hours.

Payment in three steps: 20 % on order, 40 % when the installation date is fixed, 40 % only after completion and handover (AGB § 5). The last instalment stays with you until everything is finished.

Frequently asked questions

Will the price you quote us stay the same?

After the free site survey you receive a fixed price that is written into the contract exactly as quoted. Not a cent more: if we miscalculate, we bear the difference. Only extra work that you request yourself after signing is charged separately, and only with your consent (AGB § 4 and § 17).

How long will we have a building site in the garden?

We guarantee installation in no more than 5 working days, otherwise the installation is free. We count the total of installation days. In our reference projects installation took 1 day (patio roof) to 2 days (conservatory, Cube). Exceptions: weather, delays on the client side, defective parts, force majeure (AGB § 8).

What happens if it leaks?

5-year watertightness guarantee from handover: if water comes through the roof, gutter joint or silicone seal, we repair it free of charge within 72 hours of your report. Under AGB § 17 the exclusions include blocked gutters, third-party damage, lack of maintenance and designs that are ventilated by construction, such as unheated conservatories.

When do we pay, and how much?

In three instalments: 20 % when you place the order, 40 % when the installation date is bindingly fixed and 40 % only after completion and handover (AGB § 5). Until you have accepted the work, the last instalment stays with you.

Who comes to build the garden room?

Our own installation team. No subcontractors, neither for the site survey nor for the installation. You also have Olja as your dedicated contact: one person, one number, for the entire guarantee period.

Do we need planning permission?

In NRW, patio roofs up to 30 m² floor area and 4.50 m depth usually do not need a building permit. Side walls or sliding doors can change that. The building authority makes the binding decision, and obtaining it is the owner’s responsibility (AGB § 10). We go through your situation during the site survey.

Glass or polycarbonate: which suits us?

Laminated safety glass is clearer, more durable and quieter in the rain. Polycarbonate is lighter and cheaper. The right choice depends on orientation, sunlight and budget. We bring samples of both to the site survey so you can see the difference.

Can we add glass walls later?

Yes. The structures are modular: you can start with the roof and add glass sliding doors, screens, an awning or lighting later. We plan for this during the site survey. Side walls can, however, change the planning permission question.

Which cities does ProMont Alu work in?

We are based in Krefeld and install throughout NRW. Reference projects include Krefeld, Neuss, Düsseldorf, Cologne, Grevenbroich, Erkelenz, Bergheim, Bonn, Königswinter, Troisdorf, Dorsten and Recklinghausen.

How does the site survey at our home work?

The site survey is free and takes about 45 minutes at your home. We measure precisely, check the wall and ground, bring profile and glass samples and answer your questions. Afterwards you receive the fixed price. No sales pitch, you sign nothing. It is best if you are both there, because it is your shared room.

Where does the material come from?

We install aluminium systems from the manufacturer Deponti with powder coating, for example in RAL 7024 graphite grey. Profiles, glass and accessories are made to measure after your site survey.

How long does the colour last?

5-year colour guarantee from handover: under normal care the powder coating shows no visible colour change. This is a manufacturer’s guarantee that we pass on to you. Near the coast, at harbours and directly by a swimming pool it applies for two years. We ourselves give a ten-year guarantee on the load-bearing structure.

How long is the fixed price valid?

The fixed price in the offer after the site survey is valid for 30 days.
