A house renovation is worth it if you save costs in the long term and increase the value of your house. Here, however, the right schedule is crucial so that you make full use of funding and do not exceed your budget.

State renovations make house renovations really attractive. In particular, energetic renovations receive grants and cheap loans. But you can also get financial support if you want to convert your home to suit your age or invest in burglary protection. To do this, however, you must first consider and plan a few things. Because only those who prepare everything exactly before submitting an application will actually receive support.

House renovation: How to create your plan

The order in which you approach your house renovation is not irrelevant. With the renovation you want to solve problems and not put new stones in your way. So first get an overview of the current state of your house. The later costs and financing options depend on where you need to renovate, where you can repair yourself and where an additional investment, in the medium and long term, will really save you money. It is therefore advisable to consult an energy consultant right from the start. Most funding programs require such a consultant anyway, so you save time and money if you have him on board and don't just rely on architects and specialist companies. The energy consultant not only creates a timetable for you, but also takes over the tedious paperwork for applications.

Checklist for your home renovation

Always consider the seasonal and regional weather conditions when making appointments. Basically: you renovate from the outside in. So you start with the roof and then work your way up to the interior.

  1. Roof renovation: roof insulation, loft conversion, roof covering
  2. Cellar renovation: cellar ceiling insulation, window replacement
  3. Exterior wall: exterior wall insulation, exterior painting, windows and doors
  4. Electrical and heating systems
  5. Interior design

You can do some of this yourself. Plant technology should be left to professionals. Those who are skilled in the art can do a lot themselves in the areas of insulation work, flooring and interior fittings. With experience and appropriate equipment, an exterior painting is also possible. Here you can save a lot of costs.

Refurbish the roof

You will encounter the subject of insulation in several places when renovating a house. It is a central component of most renovations, since energy-saving measures are regulated in many construction projects with the Energy Saving Ordinance (EnEV). But this is exactly where you can reduce your costs in the long term and receive numerous funding opportunities. It is therefore not surprising that the first step in renovating a house is roof insulation. If you re-cover your roof anyway, rafter insulation is worthwhile. It is a little more expensive than an intermediate or sub-rafter insulation, but it is also a lot more effective. If you decide on a cheaper option, you can also do the insulation yourself. An energy saving of on average five to seven percent is only possible if implemented properly. Please note that you only qualify for some grants if the insulation is accompanied by an expert.

When it comes to loft conversions, you can do a few things yourself, such as cladding or laying the floor covering. If you want to use the roof as a living space, here are some guidelines to follow (escape routes, fire protection). You should hire professionals for electrical and heating installations. The same applies to the roof covering. The easiest way to save money is on the material. Clay and slate are expensive. Concrete, bitumen or metal are cheaper.

Refurbish basement

You can also save a lot when renovating the basement. Because non-insulated basement ceilings let the living rooms cool down more quickly. With effective basement ceiling insulation, you will therefore save some heating costs. Your budget planning for the basement depends on the material used and the thickness of the insulation layer. If the basement is divided into many small rooms, you will have to plan more time for the house renovation because you work on a smaller area.

Refurbish facade

The most effective thermal protection measure is external wall insulation. You can save 20 percent of the energy costs. But here too, an expert must be on board if you want to apply for grants. If the facade insulation is slopped, moisture damage can occur in the interior. So if you have no experience with this, you should leave the insulation to professionals. On the other hand, painting the facade is feasible - even if not everyone can achieve clean, even painting. You also need a scaffold that you can borrow from specialist companies. Also plan cleaning repairs - also a possible do-it-yourself job. When it comes to paint, you can choose between inexpensive lime or plastic emulsion paint and resistant silicate and siloxane paint.

Heating system and electrical installation

If you want to replace your old heating system with a modern condensing boiler, subsidies are available for various systems. You can save up to 30 percent of the energy costs here, but you have to plan an average of between 5, 000 and 10, 000 euros. Depending on the system, you may have to install a heating pump, replace the radiator or isolate the pipes. Electrical installations cost around 100 euros per square meter. If you are flirting with a smart home, installing a smart home control is often a little more complex. However, there are also systems that you can easily put into operation yourself.

Financing your home renovation

Equity, debt, funding - with these three pillars you finance your home renovation. Usually nothing works without equity. You usually only get loans if you have equity or collateral such as building society contracts. You can also use private loans to meet your starting requirements. Alternatively, you can also get cheap loans from the state's credit institutions. Compare all of the options before committing to a worse deal for convenience.

Grants for your home renovation

Both KfW (Kreditanstalt für Wiederaufbau) and BAFA (Federal Office of Economics and Export Control) offer various grants for house renovations. In particular, the energetic house renovation is supported here. But there are also funding programs for age-appropriate conversions and burglary protection. So you can benefit multiple times. You even get grants for your energy consultant. The following generally applies to KfW and BAFA: First make sure that the planning is correct. Only when you have all the supporting documents do you apply for funding. If this is approved, work can begin. KfW and BAFA funding can often be combined.

KfW and BAFA grants for house renovations
