Tips for requesting your aluminum carpentry quote with Reformia
The average price of aluminum carpentry can vary considerably from one element to another. A simple sliding window without a blind can cost from 100 € onwards, but with thermal break and wood-effect finish, the cost can reach 400 €.

1. When looking for aluminum carpentry for doors and windows, you should first weigh your priorities. It's important to decide whether you prefer design to be a priority, if what matters most is that the doors and windows let in plenty of light, or if you're looking for models most suitable for thermal and sound insulation.

2. Once priorities are clear, they should be specified in the quote. Currently, aluminum finishes and profiles are enormous in variety, and any guidance will be helpful so that the aluminum carpentry company in charge of the project can correctly understand what is needed.

3. It's important to find out if there are any types of assistance available to replace the aluminum carpentry in your home. Sometimes there are subsidies that help improve the energy efficiency of homes, and modernizing aluminum carpentry may be included in them.

Steps to replace aluminum windows without major work
The average price of aluminum carpentry can vary considerably from one element to another. A simple sliding window without a blind can cost from 100 € onwards, but with thermal break and wood-effect finish, the cost can reach 400 €.

1. If the priority is to install a new aluminum window with minimal work, you should choose easy-to-install models. It's advisable to ask the contracted technician for advice on this.
Aluminum carpentry offers easy-to-install window models that minimize structural work. For basic budgets between 100 € and 200 €, it's advisable to consult with the technician about which window type best suits your home, considering material, size, and insulation features.

2. The next step will be for the contracted installer to remove the old windows without causing any damage to the frame or walls.
The installer must carefully remove existing windows without damaging the frame or walls. This work is crucial in any aluminum carpentry budget, as poor removal can affect total costs and generate additional repair expenses.

3. Next, the new windows are installed in the opening, where the new window must fit properly and level.
New windows are installed in the existing opening, ensuring they are perfectly level. In standard services between 250 € and 350 €, precise placement is included to guarantee optimal aluminum carpentry performance.

4. The technician must add thermal insulation to promote better insulation, mainly to be applied at the joints.
The technician applies thermal insulation material to the joints and edges of the new window. This step is essential in premium budgets (400 € – 600 €) and significantly improves your home's thermal and acoustic insulation.
What can change your final price
Even similar projects can end with different budgets. These are the factors that most often push costs up or down.
Profile type and thermal break system
Basic profiles without thermal break are more economical, while thermal break systems (TBS) can increase the price by 50-100%. Wood-look finishes or special colors also significantly increase the cost.
Element complexity and accessories
A simple sliding window costs less than a system with integrated blinds, special handles, or security locks. The addition of insect screens, weatherstripping, or motorized systems notably increases the budget.
Dimensions and quantity of elements
Pricing is typically calculated per unit or per square meter. Larger projects usually benefit from volume discounts, while small or custom pieces may incur surcharges for manufacturing.
Need for construction work and removal of old elements
If removal of old carpentry, adjustment of openings, or minor masonry work is required, these are billed as additional services and can double the total project cost.

The average price of aluminum carpentry can vary considerably from one element to another. A simple sliding window without a blind can cost from 100 € onwards, but with thermal break and wood-effect finish, the cost can reach 400 €.
On the other hand, the notable price difference between simple aluminum profiles and those with thermal break must be taken into account. And, in addition to that, you'll need to consider issues such as the opening system for doors, the quality of the aluminum, or whether it's combined with others, such as glass.
These are all matters that should be taken into account when choosing aluminum carpentry, as, for example, in outdoor spaces thermal break ensures good insulation, while indoors combining with other materials provides distinction.
- A sliding window of 100x120 cm costs from 100 € onwards. If it's tilt-and-turn, the price can rise to 200 € and with thermal break the price will rise above 350 €.
- A simple aluminum door can cost around 250 €. Combined with glass and in a more refined design, the price can double.
- An aluminum broom cabinet would cost from 200 € onwards. In the case of garden furniture or a tool cabinet, the price can reach 500 €, depending on the dimensions.
- Closing a terrace of medium dimensions with aluminum structure can cost around 4,500 €. In the case of a porch, the price will exceed 5,000 €.
