How much does the complete renovation of the house cost?

How much does it cost to renovate a house? When it comes to the cost breakdown to modernize a single-family home, many aspects come into play. There is therefore both a cost calculator for the renovation of an old building and a renovation calculator for the single-family home. With the help of our free online calculators, you can calculate the costs of façade insulation or find out what costs the renovation of the windows entails. You can estimate the painting costs and calculate the new heating system in the cost calculator. With the renovation calculators online, you can not only find out the renovation costs, but also consider them as an energy-saving calculator for the house.

House renovation: Use the cost calculator and create a cost estimate for the renovation of an old building

Would you like to modernize your house and are wondering what costs a house renovation entails? This consideration is justified, because the renovation costs for an old building extend to several areas. The façade renovation causes costs just as much as window modernization causes costs. In the course of the renovation of the building envelope, these two aspects absolutely belong together. Because with insulated walls with old, leaky windows, these become cold bridges. Moisture and mold could be the result. In addition, the renovation of the old building incurs costs relating to the equipment with a suitable heating system and the final painting work.

So that you can calculate the modernization costs in advance, we offer you our Efficiency House Online Renovation Calculators tailored to the trades. With them, you can quickly and easily calculate the renovation costs in advance. Calculate the energy savings through insulation online free of charge with our façade configurator. Or use our practical window cost calculator. You can also find out the painting costs with the painting costs online calculator. Finally, with our heating calculator, you will get an overview of the costs that a heating renovation incurs.

Calculate insulation and façade renovation

If you want to renovate the façade of your house, insulation is a significant component and cost factor. The background to this is the high energy requirements set by the Building Energy Act (GEG). The GEG merges the former Energy Saving Ordinance (EnEV) and the former Renewable Energy Heat Act (EEWärmeG). The requirements of the GEG are designed to equip both renovated old buildings and new buildings with more renewable energies. However, their optimal efficiency is usually tied to a high insulation standard of the respective house. For this reason, good insulation is part of façade modernisation.

The background to this is also that if you are renovating an old building to make it more energy-efficient, you can only reduce the costs with a subsidy from the BEG (Federal Funding for Efficient Buildings) if a certain energy-efficient building standard is achieved. In order to save energy and heating costs, the heat generated should be kept inside the rooms by a building envelope that is as airtight as possible. With the help of good external insulation, up to 20 percent of heating costs can be saved.

If you want to know the cost per m² for a façade renovation, you should first be clear about what exactly the façade of a house actually is. From an energy point of view, the façade is all the outer walls of the house – except for the roof, basement and foundation. As a rule, external insulation is used in the renovation of old buildings. If there is a listed building, however, interior insulation may also be appropriate. For this reason, our façade renovation cost calculator offers a choice of external insulation composite systems (ETICS) as external insulation and blown-in insulation as interior insulation. This allows you to calculate the exterior wall insulation and generally get an overview of the costs for façade renovation.

The abbreviation ETICS refers to a multi-layer construction that is attached to facades for insulation. All ingredients used are precisely matched to each other. The ETICS panels are glued or dowelled on the façade. When renovating old buildings, it is usually recommended to use dowels, as you often do not know the adhesive removal values of the old wall surface. The insulation layer of the ETICS can consist of the following materials, for example: rock wool, mineral wool, polystyrene rigid foam or cork boards. The plaster applied to the outside of the ETICS, the final coating, can be mineral plaster, silicate plaster, synthetic resin plaster or silicone resin plaster. If you are planning to insulate your house with ETICS, you will learn in the renovation calculator that this is a cheap option for insulating your old building. With ETICS, you can therefore significantly reduce renovation costs.

Blown-in insulation is used in the renovation of old buildings and subsequent insulation when the masonry has an air layer. Here there is a cavity between the inner supporting shell and the outer facing shell. Loosely poured insulation material is filled into this space during blow-in insulation. This can be polystyrene or granules made of rock wool, for example. The great advantage of blown-in insulation is that the dimensions of the insulated surfaces can remain unchanged – and that the external appearance of the house is preserved. This is particularly relevant for buildings that are listed buildings. In the calculation of the renovation, blown-in insulation also gives a good picture: The façade renovation costs per m² are even lower with blow-in insulation than with EIFS.

Use our calculator as an exterior insulation cost calculator for energy-efficient renovation! This way you can find out the current prices for façade renovation conveniently online and free of charge. Are you already in talks with a craft company and have received a cost estimate? Then use our façade insulation calculator to check whether the costs for the façade renovation of your single-family home are within limits! If not, we will be happy to look for façade builders in your area who offer the same service at a better price.

Old Building Renovation Costs: Use Your Computer and Find Out Prices

Would you like to insulate the façade of your old building? Then you should find out in good time about the costs of façade renovation in an old building. When calculating the costs, it is first important to know what type of house it is. This is because the costs for façade insulation in an apartment building are higher than in a single-family house due to larger areas. For this reason, our "renovation calculator for old buildings" first asks what kind of home the modernization is. The modernization costs depend on what you enter in the renovation configurator. Our house insulation cost calculator therefore shows you various options for insulating the old building, including the prices incurred.

Old building insulation is retrofitted thermal insulation. There are various options here, which have already proven themselves many times over in practice. On the one hand, you can start with roof insulation: Depending on the building situation and use, new insulation is installed between, on or under the rafters. When it comes to façade insulation, a thermal insulation composite system (ETICS) is suitable for the façade. In this case, the façade insulation is relatively easy to calculate. For a wooden or slate façade, a curtain wall with thermal insulation, cladding and rear ventilation can be useful. If you want to calculate the costs for such a façade renovation, it will be more challenging, as this process must be very individually tailored to your house.

Since insulation work is also an energy-efficient upgrade of your old building, the insulation of the building envelope with exterior walls, roof surfaces, floor ceilings or even curtain walls is eligible for funding in the BEG. With the help of generous government subsidies, your cost breakdown for the renovation of the old building can be adjusted in your favour.

Our renovation calculator for the old building will help you determine the costs for the façade renovation of the old building. Our calculator also shows you what your house renovation costs per square metre of façade.

Window calculator – calculate window costs easily

Windows are a central part of the energy-efficient renovation of a house. How well they seal building openings and thus protect the house from heat loss depends on the tightness of the windows and the quality of their installation. The material of which the window frames are made plays a subordinate role: due to the constant weather influences, windows usually have to be replaced after about 20 to 30 years. In any case, new state-of-the-art windows help to improve the insulating effect and thus the insulation standard of a house. Tight windows help to reduce energy costs immediately – because the heat is not simply lost.

You can find out what costs you have to expect for windows when renovating an old building in our window energy calculator - the program can quickly calculate the window price free of charge. Find out the cost of new windows for your entire house! The number of windows is relevant as well as their size and design. Our renovation calculator for window renewal therefore asks for all these points for your property. The calculation for your house renovation is completed by the result of our online calculator by the relevant cost item of the window renovation. Keep in mind that window modernization is also eligible for funding with the BEG – the state subsidies significantly reduce your cost burden for new windows.

Use our modernization cost calculator to calculate the costs for your new windows. With tight windows, energy consumption decreases and with it heating costs significantly. With the help of window modernization, you reduce costs in the long term – and also make a valuable contribution to the energy transition. In coordination with the insulation of the entire house, new windows ensure an optimised living climate.

Calculate painting costs: How high are the painting costs per square meter?

The painting of buildings, both inside and outside, fulfils both aesthetic and functional tasks. This is because a suitable exterior paint protects against the weather and thus contributes to the insulation standard of a building. The costs for exterior painting on the house, also known as painting costs, depend not least on the type and quality of the paint. It should be taken into account, for example, that lime paint is cheaper than silicate paint – but also less resistant. When calculating your painting costs, in addition to the type of paint, the painting costs per square meter are also important. Because whether painting costs for 70 square meters or 50 square meters are incurred in individual rooms of a house already makes a difference - the painting costs for an entire house are consequently even higher. This is due to the increasing amount of paint and also the higher number of man-hours required for a larger wall area.

When calculating the painting costs to have your façade painted, you should take into account not only the aesthetic aspect and weather protection, but also the fact that these costs are also part of the energy-efficient renovation. This is because a façade renovation that serves to save energy includes plastering work and painting in the last step. It is no coincidence that the Federal Funding for Efficient Buildings (BEG) co-subsidises painting costs as a so-called "environmental measure". If you now calculate the painting costs online and subtract the percentage BEG subsidy from the investment amount, you will see that the painting costs per m2 decrease significantly. Of course, this is also the case if your painting costs include wallpapering and the removal of the old wallpaper beforehand.

Use our modernization calculator for the house to calculate the upcoming painting costs. If you know the costs for painting and plastering in addition to the costs for other trades, you are already a good deal closer to the answer to the question of how much a house renovation costs.

Heating calculator: Calculate heating online

Building heating systems account for a large proportion of climate-damaging CO2 emissions. If you now activate a heating calculator, you can just as well speak of an "energy saving calculator for heating". If you ask yourself how much a complete renovation costs, you will quickly realize that a new heating system accounts for a significant part of the costs - that is, the renovation costs per square meter increase with the amount of the heating investment. The fact that heating systems are so cost-intensive is due to the strict requirements of the GEG (Building Energy Act), whose requirements are based on the strict government requirements for achieving climate targets.

With the heating calculator for your house, you can find out which heating system is suitable for your house based on your information - and what costs you will have to pay. As a general rule, renewable energies are more expensive to purchase, but ensure long-term savings in heating costs. However, with the price result for heat pumps and the like from the heating calculator online, which may seem frightening at first glance, you should not forget the high BEG subsidies. The generous calculation of the BEG heating subsidy for renewables clearly shows the state goal: because they make the purchase of a new heating system attractive through large savings.

Use our heating calculator online and use the free tool to calculate what investments your modernisation concept for a single-family home will entail. The same applies to heating in the semi-detached house or apartment building: Because you calculate your renovation costs in advance – for the house including heating – your cost breakdown for the renovation has hand and foot right from the start. They know the upcoming expenses and can therefore concentrate on funding in addition to planning. Apply for BEG funding from BAFA or KfW. One application is enough to receive a handsome subsidy for the modernization of heating systems to heat pumps or pellet heating systems.
