Windows And Doors Care & Finishing

Wooden windows and doors offer a warm and inviting ambiance all year round. They help maintain a comfortable indoor climate while protecting the premises from external noise and weather conditions. Wooden units are superior to other designs because of their natural thermal insulation properties. From an environmental standpoint, wood is the ideal material for producing window and door structures.

Some benefits of wooden windows and doors include:

  • Durability and excellent protection
  • Versatility in terms of design and decoration
  • Promotion of a healthy indoor environment
  • Energy and cost savings
  • Positive eco-balance

Wood is subject to constant stress from environmental factors like sun, wind, moisture, and temperature changes, as well as potential damage from fungus and mold. To protect your wooden windows and doors from these factors and extend their lifespan, it’s essential to properly treat and care for their surfaces.

It’s important to remember that interior doors also require careful treatment. With constant opening, closing, and accidental contact, door finishes can become dirty and scratched. Therefore, it’s necessary to care for interior doors to maintain their appearance. Although the process is similar to caring for windows, there are some unique considerations depending on the type of door.

What do you need to pay attention to when installing wooden windows?

Proper installation of windows and doors requires careful consideration to avoid damaging the coating. Here are some important points to keep in mind:

  • Protect the window surface from contact with plaster, mortar, and screed. The optimal solution is to use special lighthouse plaster strips with a protective film attached.
  • If plaster strips are not part of the window installation process, then the protective film must be attached with adhesive tape. Only use special tape for this purpose, and ensure that the tape remains in contact with the window surface for no more than 2 weeks. After 2 weeks, remove the tape carefully and avoid using sharp objects that could damage the coating.
  • To prevent condensation from forming on the inside of the window during installation and finishing work, it's important to set the "slot ventilation" mode of the fittings. This will allow proper air circulation and prevent moisture buildup.

    It's also important to ventilate the room to prevent damage to paintwork and wood caused by building moisture. During construction work in the winter, it's recommended to combine room heating with ventilation to prevent moisture buildup. Additionally, when plastering and laying the screed, make sure to ventilate the room several times a day.


Wood is a timeless classic, especially when it comes to doors. They are durable, but require selective care and are not compatible with harsh detergents, brushes, and hard sponges. However, there are special detergents made specifically for wood that work well.

Another effective, albeit old-fashioned, method of cleaning is to use alcohol. To do this, make a water-alcohol solution in a 9:1 ratio.

If the door’s coating has lost its aesthetic appearance, you will need to gently sand the affected area. Then, apply wax to the surface and buff it in until a uniform shine appears.


Harsh abrasive cleaners are not suitable for cleaning veneer doors. Even soft products with solvents can cause scratches and damage to the surface. The best way to care for interior veneer doors is to wipe them regularly with a soft cloth to remove dirt and dust. Occasional cleaning with a mild detergent is also recommended.

To restore minor defects and enhance the shine of the door, a polish containing wax can be used. This helps to improve the barrier function of the coating, fills in microcracks, and gives the doors a fresh appearance.


In terms of maintenance, a PVC interior door is the most convenient option. Cleaning its surface requires only warm water and a soft cloth with a mild detergent. However, abrasive cleaners should be avoided.

For repairing damages, a special putty paste can be used to fill in chips and cracks. For minor scratches, a regular stationery proofreader can be used as well.


Caring for interior doors with a laminated coating requires avoiding harsh chemicals and abrasive agents. Instead, a water-alcohol solution is a good cleaning agent. For minor imperfections, a wax pencil can be used to hide cracks by filling them when heated. However, the cracks are not completely fixed, but they become less visible. Overall, caring for interior doors is not complicated, as long as one follows the rules. Additionally, it’s important to remember that doors need regular adjustment and lubrication to function correctly.
